  1. Hi, I get a strange problem when I try to insert images data into media table. I decided to break down the problems section by sections. I rewrite the query using basic mysqli_query() function and insert one row at a time for testing purpose. Here is the strange thing, when I pass the value as variable into the VALUES, the insertion will fail and return an error: 'insertion failedUnknown column 'edvard' in 'field list''. However, If I just pass the string into VALUES(), the insertion goes without problem. I haven't run into this sort of problem before, can anyone explain the reason please. Tha
  2. Hello there, It's my first time asking question here, so I want to introduce myself a little bit. I was a graphic designer and 3D artist and I have never done any website except using iWeb. The company I work for needs to rebuild its website which has roughly four thousand products in the database. The website was built by hosting company using a open source CMS called OScommerce. My given project was to create a independent website using php and mysql that can be easily modified to suit the need when time is changing. When I receive the project around beginning of this year, I knew not
  3. I just wanted to say a huge thanks to Larry for writing the book "PHP and MySQL for Dynamic Web Sites" (I have the 4th edition). To give a little history - I started using PHP about 10 years ago when I was asked to create a portal for some members of a small department that wanted to share information relating to health care. I initially looked at creating a static HTML site but soon came across PHPNuke. I know this particular CMS has had better days but for me 10 years ago it was revolutionary. I managed to set up a website and installed PHPNuke (including the database on MySQL). I wa
  4. Hello, I am fairly new at php and mysql but finding the book very useful. I am having trouble with trying to register an account I fill out the registration form but when I click submit all I get is "Please enter your username" I am not getting any error appearing so I can not find out what the problem is. Here is my code I hope it is easy enough to read. I am also using a test server on 000webhost ("http://testwebserver.comli.com/register.php") I also have a localhost. <?php # register.php require('includes/config.inc.php'); $page_title = 'Register'; if ($_SERVER['REQUES
  5. My brain must be dead, because while I read the book, I am having trouble devising a solution to this problem. I would like to include a button on a page of query results that allows users to filter the results to those that match only certain criteria. I realize that it's not a good idea to run a whole new query just for this filtering, so I have been trying to look for a solution, but to no avail. Any tips? I'm sorry for being vague, I'd just rather not give away too much about the site's structure. Thank you!
  6. The most basic of questions .... how do I access the phpmyadmin dashboard (fig 4.8, p 120? I was initially able to get this dashboard using /localhost/phpmyadmin. I then set a root password in App. A in order to use MySQL Client. After that I wasn't able to get the phpmyadmin dashboard, getting the error shown in fig 4.9 on p121 instead, which referred me to App A to create a user. I did this. Created a user in Appendix A, and validated it, getting the blank screen shown in fig. A-15 on p. 599. But when I type in the URL of localhost/ phpmyadmin, I'm still getting fig 4.9. What am I missi
  7. I have been working on a website where users from all around the world would post their suggestions, upload photos and create events for hangouts and so on. Its just like a social network. I need to how to store the Data and time of all the users in the correct format so that it would be the best choice for the future of the website. For example if a user in US creates an event then a person in india seeing it must be seeing it correctly in his time format. If he chooses to fly to US and login's in US then the time for the user in that specific timezone must match. The thing is any where t
  8. how can i add login and registration to the forum example in chptr 15? Why doesnt it tell u exactly how to do to implement the login functionality?
  9. In this example why does the procedural way fail with this error: Error: Warning: mysql_fetch_assoc() expects parameter 1 to be resource, object given in /Users/joel/Sites/people_test/public_html/index.php on line 14 PHP: $dbc = @mysqli_connect (DB_HOST, DB_USER, DB_PASSWORD, DB_NAME) OR die ('Could not connect to MySQL: ' . mysqli_connect_error() ); $q = "SELECT first_name, last_name FROM person LIMIT 0,30"; $r = mysqli_query($dbc, $q); Procedural: while($data = mysql_fetch_assoc($r)) { $rows[] = $data; } //prints out null echo json_encode($rows); OOP: while($data = $r-&
  10. Edit: Nevermind do not worry about this thread. Apparently my action attribute for my login form should have been "index.php?p=login". When I give correct login info, it works correctly so I just need to fix the conditional for when the login info is incorrect. Okay so I tried setting up a modular website with the standard header + left sidebar, content, and right sidebar + footer. I also want to include the ability to register / login and put up a "Home | Login" or "Home | Settings" links up at the to of the header depending on whether someone is logged in or not. Now, for some rea
  11. Hello! I have been reading over the great guide for Stripe integration. Great stuff. Thank you for doing those posts. What I want to do though, is use the custom button CHECKOUT method, which is shown here: https://stripe.com/docs/checkout#api along with the "saving customer details for later", method. Which is shown here: https://stripe.com/docs/tutorials/charges#saving-credit-card-details-for-later Can these two things be combined with your methods at all? I am having no luck at all with this.
  12. Hello, I have been trying to get my form to validate the radio button which allows my user to agree to the terms and conditions, however, it either prints at the top of the page or not at all. The other prompts print near the form input which is what I would like to happen for the radio button. Following is my code. if (isset($_POST['radio_Agree'])) { $Agree = mysqli_real_escape_string($connect, $_POST['Agree']); } else { $reg_errors['radio'] = 'Please agree to the user Terms and Conditions.'; } <p><label> <input type="r
  13. Hi Larry, Great fan of you books! I've recently gone over Chapter 11 and I had a question regarding passing data from JSON to PHP using the code provided in the book for test.js (434-436). I've modified the script to use JSON and that works beautifully. I'd like to know if there is a clean JS solution to pass data to PHP without relying on jQuery.ajax({ data })? I've looked everywhere for a solution but the solution seems easily resolved with jQuery, but I'd like to avoid that if possible. Here is the code I've used as dictated in the book: window.onload = function() { 'use str
  14. Per instructions and examples in the book, I am using javascript to initiate use of mysql within a php file to populate the data in a grid within my original javascript file. Everything works fine! However, sometimes, it takes a few seconds for the php file to complete running. I am finding that I need to disable the grid until the php file has completed. I know how to disable the grid using jquery $.blockUI(); and re-enable the grid using $.unblockUI(); using javascript commands in my javascript file. But I cannot figure out how to delay the $.unblockUI(); until the php file has completed
  15. Hello there! The thread referenced (at the bottom) covers how to display two forms on a single page. However . . . In the case referenced, both forms are visible on the page by default, and it is only *after* a submit has been detected that the script detects the form sent, and calls the appropriate code. It seems possible to display only one of the forms based on a user's site visit status. For example, assume a page contains code for both 'Form A' and 'Form B'. What I'm looking for is: 1) When the user visits the page for the first time, 'Form A' is displayed by d
  16. version 0.5 Page 129 As I read this book, I keep scratching my head, wondering what's so good about OOP (Object Oriented Programming). The clips example is a case in point. Why write 5 lines of code when you can write just 2, like this? $stockQuote = 'AAPL: $533.25'; echo $stockQuote; I can modularize my procedural code by using includes. So how can all the fuss and bother of OOP be worthwhile? I've read plenty of rationales defending OOP, written by people who studied it in college, but it seems more like a religion to me. Sorry, I don't mean to offend anyone. I've re
  17. I have gone into the database and explored what might happen after PayPal has been activated and is live. So I have manually changed some of the expiry dates of my users. This is my code when the registrant originally joins: $q = "INSERT INTO users (username, email, pass, first_name, mid_initial, last_name, agree, date_expires) VALUES ('" . stripslashes($u) . "', '$e', '" . get_password_hash($p) . "', '" . stripslashes($fn) . "', '" . stripslashes($mi) . "', '" . stripslashes($ln) . "', '$agree', SUBDATE(NOW(), INTERVAL 1 DAY) )"; Thus their expiry date is one day less than whe
  18. After my web hosting company (1and1.com) switched from PHP 4 to 5, a script that once returned the current year A-OK no longer works; it now generates this error message that is e-mailed to me every time a page bearing this include is accessed: An error occurred in script '----------/includes/footer.php' on line 4: <br />date_default_timezone_get() [<a href='function.date-default-timezone-get'>function.date-default-timezone-get</a>]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_def
  19. hi guys ! i have question about output buffering(chapter 18 page 561) i have searched google about it and it came with alot of debates, some say its good practice, some say its bad practice to use it, but they dont provide any code for testing why its good and why its bad.. so the question is : is it a good practice to always use it ? as Larry's statement in the book that says "There can be a performance improvement with output buffering, but the main benefit is that it eradicates those pesky headers already sent error messages." if its bad practice, please give good reasons
  20. I have modified form_functions.inc.php to radio button for suit for me. But It seems its not working.. This is my code so far.. from form function if (preg_match('/sex\d{1}$/', $name)) { $i = substr($name, -1); $name = substr($name, 0, 3); $sex = array(1=>'Male', 'Female' ); // Display the error first: if (array_key_exists($name, $errors)) { echo ' <span class="inline-error">' . $errors[$name] . "</span>\n"; } echo '<input type="' . $type . '" name="' . $name . '"
  21. Hello... I have a form to get some urls from users. Eg: Web Address, Facebook Address, Twitter Address, Google+ address etc... My problem is how I validate these urls when they submit the form. I tried to validate URL in PHP by using the FILTER_VALIDATE_URL or simply, using regular expression. Here, I would like to know what are the best methods to get such a urls from users. Is it always good to let them to enter protocol? sometimes they may not know it is http, https, ftp, ftps.. etc. I think it is something hard to do some users. I tried something like this using FILTER_VALIDATE
  22. So I am looking at developing a jobsboard, which has three tables: Company - Store details of companies looking to advertise jobs, build profile. Jobs - Store details of Jobs being advertised for a certain period of time. Orders - Store details of the transactions for the jobs being posted. The way it works is the company completes registration form, then has the option of posting jobs which they will be charged a fix fee. Now what foreign key would I store in the Orders table? since I am using Paypal and don't know how much information you can carry over. Would I store the Compa
