  1. Hello Larry and Hello Community, I bought book php and mysql for dynamic web sites in english from USA since i didn't see it in my native language. I gave a look all book for make general feeling and then i will read better and careful example and teching suggestions. Book is very very good in my opinion. My question is about what is best techinque to store html inside mysql database. I'm studying a bit how work CKeditor, but i think many html editor work more or less in same way, and it use a textarea to collect the html, so what you really need to do after a submit or simila
  2. I don't know if anybody can put me through how to install composer on live server as I find little or no success at all on the net about how to do it
  3. Script 10#4 works for pagination, in my case 6 pages. Script 10#5 sort on First Name and Last Name work on the initial page display after selected column heading but not for selecting pages after the sort selection. My url shows view_users_3.php as I save each iteration of the scripts to review. Viewing my page then selecting sort by last name shows: url = view_users_3.php?sort=ln The first page of results displays correctly by last name. selecting the page 2: url = view_users_3.php?s=10&p=6&sortln The second page of results is showing user_id's 10 to 19 so has not
  4. i have some css tags in the header for my stylesheet and bootstrap and i tried to include the header.html as learnt from the book but it failed to load up instead it load up plain html. -My index.php: <?php require ('includes/config.inc.php'); $page_title = 'Homepage'; include ('includes/header.html'); ?> <?php include ('includes/footer.html'); ?> -My header.html: <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content="width=dev
  5. Good day! First off, great book sofar! I am only on chapter 2 and I love it. (I don't have excel tho so unsure if the database parts will work) Anywho, I am creating different handle_forms to see if I can have it give different responses as I go along. However, it constantly reverts back to handle_form.php even when I go into the html document and change <form action="handle_form.php" method="post"> to <form action="handle_form1.php" method="post"> Am I missing something on how to do that to test different forms?
  6. Hello, Hope you are doing great. I belong to a web development community and recently got hired in a logo design company to manage their site development issues. Basically, the website is designed quite well without any front-end issues but it has some backend issues that needs to be fixed. As they have given me a new task to add up a CMS into the backend of their website. I have already worked on Word press so I know how to configure it but as they want it on Drupal platform, I don’t know much about it. Although I have used Drupal and other CMS sites too but never got a chance to configure it
  7. Hi Larry I thought that I'd post this as it might help other php-ers. I have a website which has many images. To facilitate the download of images, I save a reduced image under a directory name e.g. images/activities/P3451098.jpg for thumbnails and slideshows as well as the full size in e.g. images/raw/P3451098.jpg. Then I can offer an enlarged image using <a href = ***><img src...... target = "_blank"> etc. The problem is that as I send the images up using FTP (Filezilla) I can't be sure if all of the reduced images have the corresponding full sized images thanks to
  8. This is related to another question I asked that I haven't managed to resolve, so I'm trying something else! I have an associative array fetched from mysql, and I need to sum values based on the value in a different column. I have created an associative array, and printed to screen and it looks okay. It returns what I need, and looks like [1] => 779700.00 ) Array ( [4] => 868.00 ) Array ( [2] => 102000.00 ) Array ( [2] => 775808.00 My problem is that I need to be able to sum the results for each individual key value pair (so eg '2' would sum to 877808.00) - there are only eight
  9. I'm having a bit of a problem which I think I might know the solution, but I'm really struggling to know the correct syntax. If somebody could point me in the right direction I'd be very grateful. I've created an application where users can create projects, and within the projects there are 'outputs' and 'inputs'. All of which is stored in separate MySql tables. It works fine. I have now been asked to create an addition layer, a 'programme' layer, which sits above projects (ie there can be multiple projects within one programme). I think I have got my table normalisation correct, I c
  10. Hi I'm trying to find out 2 things, 1) how to pass a button value that comes from mysqli while loop to javascript then on to Ajax script. 2) how to pass a php array on to javascript and then onto the Ajax script. I will be really grateful if anyone could help. many thanks sam
  11. Here's a general question... I suspect most of us have done it at some time - I certainly have - uploading a program by mistake to a server, that has an infinite loop in it (usually 'while(){....}') which means that the program whizzes round a million times sending hundreds of error messages to your e-mail address. QUESTION: Eventually the server will kill the program automatically, but is there any way (in php or otherwise server-side) to kill it? I suppose one could add a line in the loop such as $x+; if (x$>'1000'){die()} to save this embarrassment! "To err is human,
  12. There is something about php that I have trouble understand coming from using javascript like angular. How does routing in php work exactly? Like how does a php site know about going to a link (/browse/coffee/Dark+Roast/2) or a shop/product link. How does the htacess file works with the site. Currently, when going to a link the /shop/coffee, it responds by not found. I tried to look it up but I don't understand it per say as it different from the way I normally do it in javascript. <body id="page1"> <!-- header --> <div id="header"> <div class="container"&
  13. I've just started this book and am really confused with an expression. Can somebody please explain the mechanism behind the expression, given below, used in Script 1.1 - sort.php return ($x < $y) // Creating an array $a = [1, 5]; // creating comparison function using the above expression function comp1($x, $y) { return ($x < $y); } // using uasort() uasort($a, 'comp1'); // output the result echo '<pre>' . print_r($a, 1) . '</pre>'; // creating the same function as above but interchanging the arguments position function comp2($y, $x) { return ($x < $y); } //
  14. I am looking to recreate the following function from PDO to MySQLi but having some problems, I've been over the PHP website to read the functions. I'm trying to modularize my code in like the MVC pattern. public function bind($param, $value, $type=''){ if(is_null($type)){ switch(true){ case is_int($value): //Thinking something like, for integer etc $type = mysqli_stmt::bind_param(i); $type = PDO::PARAM_INT; break; case is_bool($value): $type = PDO::PARAM_BOOL; break; default: $type = P
  15. OS: Windows 7 php version: 5.5.8 (running on EasyPHP Dev Server 14.1 VC11) Browser: Firefox 40.0.2 (same results in Chrome and IE) I am having problems with the show_image script in chapter 11. When I select an image from the list it opens a popup window of the appropriate size but with no image. In firefox I get the error message: 'The image "http://127.0.0.1/scripts/site/show_image.php?image=Picture.png"cannot be displayed because it contains errors.' When I use the Web Developer menu to View Response Headers all is as expected except that it lists Content-Length: 0. I commen
  16. Hi Larry, Hope your having a good day today as you read this message. I just want to get some advice from you personally. My problem is I really would like to be a good programmer like you larry. But I think that cannot be accomplished easily. I just wanna know what are your strategies when your just starting out as a developer. How many hours you read a book in PHP js or mysql? and how do you know if its time to move in a diff topic like ex. procedural to object oriented. Coz I think I'm having a bad habit of reading a book like, after I read a single book i'll read another book right aw
  17. I'm having an issue with mysql_real_escape_string. This is used to display a custom post type (food menu items) for the WooThemes Diner theme (for WordPress). Food menu items no longer display on the Diner menu page because they are being called with mysql_real_escape_string. What is the proper way to call these items? Theme: Diner by WooThemes version 1.9.8 (now retired from active support) Affected file: admin-interface.php Lines: 111 & 118 /*-----------------------------------------------------------------------------------*/ /* WooThemes Admin Interface - woothemes_add_admi
  18. So...I'm just getting really frustrated now. I've been reading through several of these chapters several times. My school always tends to not choose books well. On to the issue though. In several sections I've noted it stating "Connect to MySQL and select the forum database." This is where the issue lies. I have MySQL and PHP installed in both operating systems of my laptop (Linux and Windows) and in neither does the referenced database exist. The book does not even state WHERE or HOW to have this included. How is a person supposed to follow the examples if some crucial component
  19. Ok I haven't followed the code 100% by which I mean only that I didn't include the XHTML parts in the <!DOCTYPE> tag. I understand that this is not vital however. Other than that I think I have followed it correctly. I keep getting http error 500 in the browser however when I try to load it. However other php scripts seem to load fine so I don't think it's a problem with MAMP. Here is my code: <!DOCTYPE html> <html> <head> <meta charset="utf-8" http-equiv="Content-Type" content="text/html"> <title>Calendar</title> </head> <
  20. In chapter 4 if I click on the Account tab once logged in, no links appear that allow me to change my password or logout, the account link is a dead link?. It is supposed to give me the option to logout and other links too. I am using the files from the download on this site. I finally found the problem, there is no bootstrap.min.js file in the downloads for this book. That is why the dropdown menu wasn't working. I went to the bootstrap site and downloaded and now it works fine. This really should be in the download files...
  21. In the source code and as well as the book you write if (isset($_SESSION['user_id']) && !isset($_SESSION['user_not_expired'])) { echo '<div class="alert"><h4>Expired Account</h4>Thank you for your interest in this content. Unfortunately your account has expired. Please <a href="renew.php">renew your account</a> in order to access site content.</div>'; } elseif (!isset($_SESSION['user_id'])) { echo '<div class="alert">Thank you for your interest in this content. You must be logged in as a registered user to view site content.</div>
  22. On page 124 it says you can use sql commands from your website to populate the database. But the sql commands I got from the download don't have any sample content, all that is in the sql commands is the commands to add the tables to the database. No content. Where can I get the file with the data to populate the tables. Please indicate the url where I can download that. I am trying to populate the pages myself but I keep getting the error which says Please select a category! I added 2 numeric categories to the categories table, but the form still won't accept it. There seems to be a problem w
  23. hello, I have starting reading the PHP and MySQL 4th edition book by LarryUllman. So far I have completed first four chapters and now starting 5th chapter. But, with time as I read further, I also want to develop good skills i.e be good in what I am learning. So can anyone suggest me some startup projects? or scripts etc I can try to code, so I can be more good in programming. Regards,

  25. I am working on the Admin area for the coffee shop site, and I am encountering an error when the query to get all products to list them on the page. I cut and paste the query because it was so complicated, thinking I would make a syntax error. I am getting an error anyway! An error occurred in script 'C:\vhosts\clever-coffee.net\html\admin\add_inventory.php' on line 94: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given Array( [0] => Array ( [function] => my_error_handler [args] => Array (
