This probably has to do with one/both of two things: 1. register_globals is off (not a bad thing - just requires a tidbit more code. see http://php.net/register_globals) 2. A variable is being called before it has been initialized.
Example PHP script: <?php echo $a; $a = "Hello World"; echo $a; ?> First you will get the undefined variable message, then "Hello World" (w/o quotes). Leaving a variable uninitialized before you use it can be a very bad thing. If your code uses that variable to do something and it's forged by Joe Black Cracker (i.e. http://host/page.php?var=forged"; - not hard to do at all) you could end up getting incorrect results or worse. What can you do about this? 1. You can ignore the errors and make the reporting of them go away. Change your Error Reporting in php.ini to a different level (see http://php.net/error_reporting for the levels and what they do). Restart your web server after this change is made (unless you use PHP as CGI, but safest just to restart it). 2. You can initialize the variables in the script before you use them. Example of 2: <?php $a = ""; //php stuff here echo $a; ?> Good luck and have fun. -Dash (.php) -----Original Message----- From: Elvin Certeza [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 12, 2002 1:52 PM To: php Subject: [PHP-WIN] newbie question (forms) I have just recently installed apache and php into my system (win98). The system test is ok....(showing php pages) Now for the question... I've created a form.. (rather cut and paste a form). This form works online I have tested it myself.. but locally it gives me an error.. When my php page loads it tells me "Notice: Undefined variable" at line whatever.. etc.. So what I've done it tested it online to see if it's the code...(full knowing that code works..since it's a cut out from a tutorial showing it's samples).. and it does work.. So the question is .. is there anything missing from my local server ???
