RE: [PHP-DB] Can't do anything with variables

Unlike Luke, I'm not familiar with this book. However, it's a pretty safe bet that it was written prior to the first version of PHP that defaulted register_globals to OFF. All of your variables for the second page will be found in the global array $_POST[] because the method for the form on the first page is POST. If you are developing on a private system, you can set register_globals ON in php.ini so that what you are learning will follow the book. As soon as you get a bit more experience, turn the register_globals back off and revise your scripts to work with the global arrays. The revision needs to be nothing more than a series of statements near the beginning of a page to initialize the local variables to the global array values. For example, $searchtype = $_POST['searchtype']; ... etc. ... Then the rest of your script(s) should work as written.

Your problem is due to the PHP error message setting in the php.ini file. Whack this at the beginning of your scripts: // Report simple running errors error_reporting (E_ERROR | E_WARNING | E_PARSE); When you know more - check out the php.ini file and read about the error level.. And this page in the PHP manual: http://www.php.net/manual/en/function.error-reporting.php Cheers, Luke Woollard -----Original Message----- From: Gilles [mailto:webmaster@bionix.net] Sent: Monday, 7 April 2003 11:18 AM To: php-db@lists.php.net Subject: [PHP-DB] Can't do anything with variables Hi all, Sorry for this really beginner question (PHP-Newbie here). I bought the book "PHP and MySQL web developpement" (Welling & Thompson) and I'm trying to recreate the exemples and it won't work. I installed PHP 4.3.1 and MySQL 4.0.12. The easy part. Here's a simple form page (from the book): SEARCH.HTML Book-O-Rama Catalog Search Book-O-Rama Catalog Search Choose Search Type: Author Title ISBN Enter Search Term: And now the processing page: RESULTS.PHP Book-O-Rama Search Results Book-O-Rama Search Results Number of books found: ".$num_results.""; for ($i=0; $i ".($i+1).". Title: "; echo stripslashes($row["title"]); echo " Author: "; echo stripslashes($row["author"]); echo " ISBN: "; echo stripslashes($row["isbn"]); echo " Price: "; echo stripslashes($row["price"]); echo ""; } ?> The problem. Even if I fill both fields, I always get "Notice: Undefined variable: searchtype" The only way it would work is if I remove all the "if" part and leave the "select * from books" (without the where clause). I don't get it. Any help would be much appreciated. Regards Gilles -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
