  1. The select query below returns 1 row when it should be 3. I am pretty sure it is because of the AVG(k.sumtotal) field. If I rewrite the query and take out that AVG(k.sumtotal) column and take out the FROM inv_ratings AS k, I get my 3 rows. I looked online for hours trying to find information about returning results using the AVG clause and didn't find much. Do I have to use a group by clause, I tried that and only get errors. If it is a group by clause please type the exact group by clause to use if you could. thank you. $p = "SELECT i.invention_id, i.inv_title, i.date_submitted, i.category_id, i.approved, c.category_id, c.category, u.image_name, AVG(k.sumtotal) FROM inv_ratings AS k INNER JOIN inventions AS i USING (invention_id) INNER JOIN categories AS c USING (category_id) INNER JOIN images AS u USING (invention_id) WHERE c.category_id = $cat AND i.approved = 'approved' HAVING u.image_name < 2 ORDER BY date_submitted DESC LIMIT $start, $display"; $q = mysqli_query($dbc, $p) or trigger_error("Query: $p\n<br />mysqli Error: " . mysqli_error($dbc));
  2. In the following code would you leave the part in where it says or trigger error and so on, on a live site mysqli_query($dbc, $i) or trigger_error("Query: $i\n<br />mysqli Error: " . mysqli_error($dbc));
  3. I am building a forum from the example in the book, and I am having trouble getting the page numbers to work like they should, right now the thread results don't update when you click on other page numbers, it is always the same query results on every page. Here is some code where I think the problem is, but I can't find it. I would post the whole page's code, but I have done that before and didn't get many helpers for that. The query I am using is $sql = "SELECT t.thread_id, t.subject, u.username, COUNT(p.post_id) - 1 AS responses, MAX(DATE_FORMAT($last, '%e-%b-%y %l:%i %p')) AS last, MIN(DATE_FORMAT($first, '%e-%b-%y %l:%i %p')) AS first, w.forum_id FROM threads AS t INNER JOIN posts AS p USING (thread_id) INNER JOIN forums AS w ON t.forum_id = w.forum_id INNER JOIN users AS u ON t.user_id = u.user_id WHERE w.forum_id=$forumid AND t.lang_id = {$_SESSION['lid']} GROUP BY (p.thread_id) ORDER BY last DESC"; $query = mysqli_query ($dbc, $sql); At the top of my forum.php page I am using this code to identify which forum the threads belong to. if (isset($_GET['id']) && is_numeric($_GET['id'])){ $forumid = $_GET['id']; } elseif (isset($_POST['id']) && is_numeric($_POST['id'])) { $forumid = $_POST['id']; } else { echo '<p class="error">This page has been accessed in error.</p>'; include ('includes/footer.html'); exit(); } Here are the page links, modified to include the forum_id in the url. if ($pages > 1){ echo '<br /><p class="center4">'; $current_page = ($start/$display) + 1; // If it's not the first page, make a Previous button: if ($current_page != 1) { echo '<a href="forum.php?s=' . ($start - $display) . '&p=' . $pages . '&id='.$forumid.'">Previous</a> '; } // Make all the numbered pages: for ($i = 1; $i <= $pages; $i++) { if ($i != $current_page) { echo '<a href="forum.php?s=' . (($display * ($i - 1))) . '&p=' . $pages . '&id='.$forumid.'">' . $i . '</a> '; } else { echo $i . ' '; } } // End of FOR loop. // If it's not the last page, make a Next button: if ($current_page != $pages) { echo '<a href="forum.php?s=' . ($start + $display) . '&p=' . $pages . '&id='.$forumid.'">Next</a>'; } echo '</p>'; // Close the paragraph. } // End of links section. thanks for taking a look.
  4. I created a script that uses the pagination example in the book, and what is happening is that, I have 8 results, if I set the $display variable at 7. I should get a page number to the second page that has the eighth result. But I don't get that, instead it totally ignores the 8th result. I looked at the code and thought the problem might be where it says $pages = ceil($records/$display), because it rounds it off, maybe that's why I lose a result. Any idea what could be causing the problem, it is the main pagination script in the book. Maybe I have an error, but after looking for hours I can't find it. $q = "SELECT COUNT(i.invention_id), c.category_id FROM inventions AS i INNER JOIN categories AS c USING (category_id) WHERE category_id = $cat"; $r = @mysqli_query ($dbc, $q); $row = @mysqli_fetch_array ($r, MYSQLI_NUM); $records = $row[0]; // Calculate the number of pages... if ($records > $display) { // More than 1 page. $pages = ceil($records/$display); } else { $pages = 1; }
  5. After reading this book and practicing, I am creating a site that has more than one main logo, I want them to alternate when the page changes to another page or is refreshed. So I thought of using the ternary operator, but I can't get it to work. Since there is no while loop involved in my header page where this code will go, I guess that's why it doesn't work. I got it to work with php's shuffle function, but that doesn't create the effect I want exactly. Anyways here is where I am at with this, any help to get this working would be appreciated. <header> $imglogo1 = '<img src="images/logo5214.jpg" alt="logo" class="logo2">'; $imglogo2 = '<img src="images/logo5213.jpg" alt="logo" class="logo2">'; $bg = $imglogo1; $bg = ($bg==$imglogo1 ? $imglogo2 : $imglogo1); </header>
  6. I want to display images on my page from a folder called forumimages. Right now it is just showing broken images. I have tried changing the directory and it doesn't work. My images are in the folder and they are jpegs. Here is the code. $directory = "../../forumimages/"; //get all image files with a .jpg extension. $images = glob($directory . "*.jpg"); //print each file name foreach($images as $image) { echo '<img src="' . $directory . '/' . $image . '" />'; }
  7. I am trying to implement a search feature to a forum I am creating and I want users to be able to search through posts. So far users type in the search terms in a form, and they go through to my $_GET['terms']. The problem is that the IN BOOLEAN MODE search only returns posts that start with or end with one of the search terms users type into the form. I want it so that the search can also return phrases that are within posts, not necessarily starting or ending with. I have tried the boolean mode operators in all sorts of ways but it doesn't work. Is it possible to use fulltext searches in this way, or should I try a different method. Here is my Mysql query I am using: $terms = mysqli_real_escape_string($dbc, htmlentities(strip_tags($_GET['terms']))); $q = "SELECT m.message, m.posted_on, s.thread_id, s.subject FROM posts AS m LEFT JOIN threads AS s USING (thread_id) WHERE MATCH (message, subject) AGAINST('$terms*' IN BOOLEAN MODE)";
  8. I have built a forum for my own website thanks to the forum example in this book in chapter 17. Now I want the capability to search through posts and show the results of the search. I modified the search.php script included in the course files. I tested it and it doesn't work properly, the $_GET['terms'] doesn't get set when I type in search terms and click search. I tested it by echoing out 'hello' after the isset($_GET['terms']) . I don't know why it isn't set though, in the address bar it is written search.php?terms=test&submit=Submit <?php # Script 17.8 - search.php // This page displays and handles a search form. // Include the HTML header: // Show the search form: echo '<form action="search.php" method="get" accept-charset="utf-8"> <p><em>Search </em>: <input name="terms" type="text" size="30" maxlength="60" '; // Check for existing value: if (isset($_GET['terms'])) { echo 'value="' . htmlspecialchars($_GET['terms']) . '" '; } // Complete the form: echo '/><input name="submit" type="submit" value="' . $words['submit'] . '" /></p></form>'; if (isset($_GET['terms'])) { // Handle the form. echo 'hello'; // Clean the terms: $terms = mysqli_real_escape_string($dbc, htmlentities(strip_tags($_GET['terms']))); // Run the query... $q = "SELECT message FROM posts WHERE MATCH (message) AGAINST ('test' IN BOOLEAN MODE)"; $r = mysqli_query($dbc, $q); if (mysqli_num_rows($r) > 0) { $row = mysqli_fetch_array($r, MYSQLI_ASSOC); echo '<h2>Search Results</h2>'; echo '<p>' . $row['message'] . '</p>'; } else { echo '<p>No results found.</p>'; } } ?>
  9. I am working on a site, and using the scripts in this book. I keep getting the error this page has been accessed in error. The script should insert a record into the database, instead it doesn't do any validation or anything else, it just gives the error message. I thought it might be a problem with the database but I can't find the problem. Any ideas.
  10. I want to integrate the forum example in the book into my website, except I would modify it so that I could have multiple forums with different topics on my site. What I want to know is what columns and tables do you think I should add to my forum database. To add to the example in the book, I thought of creating a new forums table, and in it having the forum_id column, as well as the thread_id foreign key column. I am new at this so if you have any suggestions at populating my forums table that would be great.
  11. I am creating a site using the registration system in chapter 18, and I am using the output buffer on every page, the ob_start() is included in every page via the header.html file. In the book it says that if we use the output buffer we won't get headers already sent error messages. But I just tested it and put a space before the starting <?php tag. And I got the following error. Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/ why does it give an error message.
  12. I have just typed out index.php for chapter 17, and the language drop down menu displays funny characters instead of the language specific letters. I typed the scripts as shown in the book. How can I debug this, is it my Xampp settings, I checked and it says the language is set to US in Xampp. In the book it says to save my page using utf-8 encoding. I don't know if that is the problem, I just saved my index.php page with the name index.php, in dreamweaver I don't see an option for the encoding to use for the page. In my header file the encoding is set to utf-8 and that file is included in index.php, so won't that do it.
  13. I have bought and read larrys php for the web 4th edition, and php and javascript. I am having trouble with the example in chapter 11 of php and javascript .. accessing a javascript function form inside php. can somesone send me an email so I can describee the problem.

  14. In this book in chapter 2 script 2.4 index.php. It says to include the configuration file: require('./includes/config.inc.php'); How can you reference a file with ./, shouldn't it be ../ I tried it and it doesn't work. Is this a mistake in the book?
  15. My show_image.php script is not working. When I click on the links the popup window comes up but the images don't display, only the unavailable.jpg image displays. I checked the uploads folder and it seems ok. I am using the downloaded script from this site to make sure the code is ok. For images.php, and upload_image.php, and functions.js, I am also using this site's scripts. I tried to see the source code from the popup window and there is nothing it is blank. Here is the show_images.php code. <?php # Script 11.5 - show_image.php // This page displays an image. $name = FALSE; // Flag variable: // Check for an image name in the URL: if (isset($_GET['image'])) { // Make sure it has an image's extension: $ext = strtolower ( substr ($_GET['image'], -4)); if (($ext == '.jpg') OR ($ext == 'jpeg') OR ($ext == '.png')) { // Full image path: $image = "../../../../uploads/{$_GET['image']}"; // Check that the image exists and is a file: if (file_exists ($image) && (is_file($image))) { // Set the name as this image: $name = $_GET['image']; } // End of file_exists() IF. } // End of $ext IF. } // End of isset($_GET['image']) IF. // If there was a problem, use the default image: if (!$name) { $image = 'images/unavailable.png'; $name = 'unavailable.png'; } // Get the image information: $info = getimagesize($image); $fs = filesize($image); // Send the content information: header ("Content-Type: {$info['mime']}\n"); header ("Content-Disposition: inline; filename=\"$name\"\n"); header ("Content-Length: $fs\n"); // Send the file: readfile ($image);
  16. In Chapter 11 in the sending email script called email.php, the $_POST['name'] and $_POST['comments'] in the $body variable are wrapped in curly braces. Why are there curly braces around them. See the code below. if ($_SERVER['REQUEST_METHOD'] == 'POST'){ if (!empty($_POST['name']) && !empty($_POST['email']) && !empty($_POST['comments'])){ $body = "Name: {$_POST['name']}\n\nComments: {$_POST['comments']}"; $body = wordwrap($body, 70); } }
  17. I am building a website after reading this book, and I am having trouble with the selected="selected" part of a select menu. Nothing is getting selected. When I click on submit form it goes through but the item I selected isn't being selected in my database. In the following code, the problem lies in the following section: where the select menu is, but I can't get it to work. help would be appreciated. <?php $optionarray = array(3 => 'Children & Family', 4 => 'Home Business', 5 => 'Advertising', 6 => 'Affiliate Programs', 7 => 'Art & Photography', 9 => 'Beauty & Jewelry', 10 => 'Blogging', 11 => 'Books, Literature', 12 => 'Business & Finance', 13 => 'Computer Games', 14 => 'Computing', 15 => 'Dating & Relationships', 16 => 'Directories', 17 => 'Education', 18 => 'Electronics', 19 => 'Entertainment', 20 => 'Environment', 21 => 'Flowers', 22 => 'Food, Drink', 23 => 'Forums, chat rooms', 24 => 'Free Stuff', 25 => 'Gifts & Shopping', 26 => 'Health', 27 => 'Humor', 28 => 'Interior Design', 29 => 'Internet Marketing', 30 => 'Miscellaneous', 31 => 'Music', 32 => 'Pets', 33 => 'Real Estate', 34 => 'Religion & Spirituality', 35 => 'Science', 36 => 'Sports', 37 => 'Stocks & Trading', 38 => 'Travel', 39 => 'Vehicles', 40 => 'Web Design', 41 => 'Web Hosting', 42 => 'Work At Home', 43 => 'Psychology'); echo '<form action="edit_your_sites.php" method="post"><select name="SiteTypeID"><option value="">Select a Category</option>'; foreach ($optionarray as $key => $value){ echo '<option value="$key"'; if (isset($_POST['SiteTypeID']) && ($_POST['SiteTypeID'] == '. $key .

  18. When I user the instanceof keyword for the Singleton class in Ch07 page 218, it is returning true. See below. // Create a second object to confirm: $TEST = Config::getInstance(); // see what instanceof thinks... if ($TEST instanceof Config) { echo '<pre>$TEST IS instance of Config</p>'; } else { echo '<pre>$TEST IS NOT instance of Config</p>'; } It is echoing that $TEST IS instance of Config. Am I doing something wrong?
  19. After exhausting searching and trying many different things and asking people about the add_print.php script in chapter 19 I am now positive that there are errors in this script. I have tried using the exact script supplied by the author in his working files and the images don't display in my uploads folder, and they also don't show up in my view_print.php page. I put the entire script up on stack overflow and got an answer that partially helped fix this. I however still don't see the images on my view_print pages. The show_image.php isn't doing it's job like it should, and I am using the exact files provided by the author. This is extremely frustrating and time consuming, one would expect the examples to be error free. Here is the fix I got on stack overflow. You need to add a couple lines of code and change one line to actually display the image in your uploads folder. The entire modified script is below.

  20. Hi Larray and all, I have edited this script to fit my project, which I cut off the first name and last name. I added the username field which looks like this: <form action="" method="post"> <fieldset> <legend>Sign Up </legend> <label>Choose a username</label> <input type="text" name="username" size="20" maxlength="20" value=" <?php if (isset($trimmed['username'])) echo $trimmed['username']; ?>" /> <label>Email</label> <input type = "text" name="email" size="30" maxlength="60" value ="<?php if(isset($trimmed['email'])) echo $trimmed['email']; ?>" /> <label>Select a password</label> <input type="password" name="password1" size="20" maxlength="20" value="<?php if(isset($trimmed['password1'])) echo $trimmed['password1']; ?>" /> <label>Confirm password</label> <input type="password" name="password2" size="20" maxlength="20" value="<?php if(isset($trimmed['password2'])) echo $trimmed['password2']; ?>" /> <input type = "submit" name="submit" value="Sign Up "/> </fieldset> </form> I followed the script 18.6 strickly, plus do the username validation like this (of course, I also initiate the $errors = array(); too: //validate the username if (preg_match('/^\w\S{2,20}$/', $trimmed['username']) ) { $u = mysqli_escape_string($dbc, $trimmed['username']); } else { $errors[] = 'Please enter a username'; } Assume that other variable validations are okay. I code like this: if($u && $e && $p){//OK // Check for unique username and email $q = "SELECT user_id from users where username='$u' AND email='$e'"; $r = mysqli_query($dbc, $q) or die("MySQL error: " . mysqli_error($dbc) . "<hr>\nQuery: $q"); if(mysqli_num_rows($r) == 0 ){ // Create the activation code $a = md5(uniqid(rand(), TRUE)); //Defined variable for language ID $l = $_SESSION['lid']; //retrieved already in the header //Insert into database, table users $q = " INSERT INTO users (lang_id, username, pass, email, active, registration_date) VALUES ('$l','$u', SHA1('$p'), '$e', '$a', NOW() ) "; $r = mysqli_query($dbc, $q) or die("MySQL error: " . mysqli_error($dbc) . "<hr>\nQuery: $q"); if (mysqli_affected_rows($dbc) == 1) { // everything's ok //Send the email: $body = "Thank you for your registration at askpro.com. To activate your account, please click on the link below \n\n"; $body .= BASE_URL. 'activate.php?e='.urlencode($e). "&a=$a"; mail($trimmed['email'], 'Registration Confirmation', $body, 'From: info@website.com'); //Finish the page echo '<h3>Thank you for registering! A confirmation email has been sent to your address. Please click on the link in that email in order to activate your account.</h3>'; include ('includes/footer.html'); // Include the HTML footer. exit(); // Stop the page. } else { $errors[]='You could not be registered due to a system error. We apologize for any inconvenience.'; } }else{ $errors[] = 'either the username or email has already been registered. If you have forgotten your password, use the link above to have your password sent to you.</'; } }else { // If one of the data tests failed. echo 'Error:<br />'; foreach ($errors as $msg) { // Print each error. echo "- $msg <br />"; } $error[] = 'Please try again'; } } The question is that: -/ When I enter value and click the 'sign up' button with the intention that I enter a duplicate email, i.e., email@website.com, it returned error like this: MySQL error: Duplicate entry 'email@website.com ' for key 3 --------------------------------------------------------- Query: SELECT user_id FROM users WHERE (username = 'dsfdsf' AND email = 'e') -/ Then I change the query to: $q = "SELECT user_id from users where username='$u' OR email='$e'"; It returns NO error, but it does not insert anything into the database, and no 'thank you message' is printed. Can you help me to figure this out? Am I doing anything wrong? Thank you. P/S: This is my users table:

  23. Hi, My product page (output) in HTML is something like this: ProductImage1 ProductImage2 ProductImage3 ProductImage4 Color1 Color2 Color3 Color4 Color2 Color5 Color6 What I'm trying to do is when I hover my mouse over any color above, an original (main) image of ProductImage will switch to another image (to match the hovered color). And that original image will be back when the mouse leaves. Example: http://jsfiddle.net/4dK2x/27/ I also added another hover function on ProductImage for switching images between front view and back view and it's working well. (You would see the two src attributes of the .main class image in my php code as follows) However, the hover function on colors is not working when I run php code to create a dynamic list. Here are my category.php. ---- $sql = mysqli_query($db_connect, "SELECT p.id,p.style,c.color_palette, GROUP_CONCAT(DISTINCT CONCAT(c.color_palette) ORDER BY p.id SEPARATOR '+') color_palettes FROM product_details AS pd INNER JOIN products AS p ON p.id=pd.product_id INNER JOIN colors AS c ON c.id=pd.color_id INNER JOIN subcategories AS sub ON sub.id=p.subcategory_id INNER JOIN categories AS cat ON cat.id=sub.category_id WHERE category='$category' GROUP BY p.id LIMIT 6"); [...] $i= 0; $Output= '<table><tr>'; while($row = mysqli_fetch_array($sql, MYSQLI_ASSOC)){ $id = $row["id"]; $color_palette = $row["color_palette"]; $style = $row["style"]; $color_palettes = explode("+", $row["color_palettes"]); $Output.= '<td><div class="image"><a href="product.php?id='.$id .'&colorpalette='.$color_palette.'"><img class="main" data-alt-src="images/'.$style.'.'.$color_palette.'.BR.jpg" src="images/'.$style.'.'.$color_palette.'.FR.jpg" width="300" height="327"/></a><br />'; $Output.= '<div class="toggles">'; for ($ii=0;$ii<count($color_palettes);$ii++){ if (count($color_palettes) > 1) { $Output.= '<a href="product.php?id='.$id .'&colorpalette='.$color_palettes[$ii].'"><img data-src="images/'.$style.'.'.$color_palettes[$ii].'.FR.jpg" src="images/'.$style.'.'.$color_palettes[$ii].'.CP.jpg" /></a> '; } else { $Output.= '';} } // End for loop $Output.= '</div>'; $Output.='</div></td>'; $i++; if ($i%4==0){ $Output.= '</tr><tr>';} } // End while loop $Output.= '</tr></table>'; ---- I think my problem is probably because the array $color_palettes[$ii] is not defined in .main class image. So if that i the case, what do I do to fix it? Any help would be much appreciated.
  24. Here is the problem I have been having. I have tried numerous things to resolve it. Nothing seems to work. I have my login script from this book and I put it on a live domain to test it. And I can login fine with Internet explorer and Safari. But with Chrome and Firefox. It always fails to log me in on the first attempt, it takes 2 or sometimes 3 attempts. I am thinking of using the code from this book to build a website but I am completely clueless as to why it is doing this. I have triple-checked my code and it is like in the book. Could it be my SQL table that has a problem. I tested the query in phpmyadmin in the SQL form, and it always returns the user_id. When I try to login the page kind of jumps and it redirects me to index.php without logging me in. I have been at this for 3 days, any help would be HIGHLY appreciated.
  25. I built a login page from the model in this book, and for some reason, sometimes when I login it redirects me back to index.php and it doesn't log me in. Other times it logs me in just fine. Any idea what could be causing this? Here is my login page code. <?php $page_title = 'Login to your account'; include ('includes/header.html'); include ('includes/config.inc.php'); if ($_SERVER['REQUEST_METHOD'] == 'POST'){ require (MYSQL); $trimmed = array_map('trim', $_POST); if (!empty($trimmed['Email']) && filter_var($trimmed['Email'], FILTER_VALIDATE_EMAIL)){ $e = mysqli_real_escape_string($dbc, $trimmed['Email']); } else { $e = FALSE; echo '<p class="error">You forgot to enter your email address, or the email you entered is invalid.</p>'; } if (!empty($trimmed['Pass'])){ $p = mysqli_real_escape_string($dbc, $trimmed['Pass']); } else { $p = FALSE; echo '<p class="error">You forgot to enter your password, or the password you entered is invalid.</p>'; } if ($e && $p){ $q = "SELECT UserID, Fname FROM users WHERE (Email='$e' AND Pass=SHA1('$p')) AND Active IS NULL"; $r = mysqli_query($dbc, $q) or trigger_error("Query: $q\n<br /> Mysql Error:" . mysqli_error($dbc)); if (@mysqli_num_rows($r) == 1){ $_SESSION = mysqli_fetch_array($r, MYSQLI_ASSOC); mysqli_free_result($r); mysqli_close($dbc); $url = BASE_URL . 'index.php'; ob_end_clean(); header("Location: $url"); exit(); } else { echo '<p class="error">Either the username and password you entered do not match those we have on file, or you have not yet activated your account.</p>'; } } else { echo '<p class="error">Please Try Again</p>'; } mysqli_close($dbc); } ?> <div class="text"> <h1>Login</h1> <p>Your browser must allow cookies in order to log in.</p> <form action="login.php" method="post"> <fieldset> <p><b>Email: <input type="text" name="Email" /></b></p> <p><b>Password: <input type="password" name="Pass" /></b></p> <input type="submit" name="submit" value="Login!" /> </fieldset> </form> </div> <? include ('includes/footer.html'); ?>
