fortnox007 Posted August 4, 2010 Share Posted August 4, 2010 Hi guys, I pretty new to php, and was writing a small script after a I read a chapter (4) about if-statements of a book. But it seems I am doing something wrong. Maybe someone could help me in the right direction. In a nutshell: I have a small form, and when someone presses submit it should go to another page and include the variables of the previous page. So far I am only been able to include html form variables which I recover on the next page with $_POST['xxxx']; here under ill Put a part of my script which is not of any use, but its more for me to understand how to get php variables on the next page. I am using a self referencing script and i have some comments added to read along. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>bla bla bla</title> </head> <body> <?php //code to be executed when monkey button pressed if (isset($_POST['monkey'])){ echo $_POST[$number1]; echo 'monkey pressed'; } //code to be executed when snakes button pressed if (isset($_POST['snakes'])){ echo $_POST[$number1]; echo 'snakes pressed'; } ?> <h1>bla bla bla</h1> <h3> <?php $number1 = $number1.mt_rand(1,100000); echo $number1; ?> </h3> <form action="<?php echo $_PHP['PHP_SELF']; ?>" method="post"> <input type="submit" value="monkey" name="monkey" /> <input type="submit" value="snakes" name="snakes" /> </form> </body> </html> Quote Link to comment Share on other sites More sharing options...
fortnox007 Posted August 5, 2010 Author Share Posted August 5, 2010 So in a nut-nutshell. How to retrieve php variables on the next page. I am pretty sure i can use hidden fields for it, but if there is another way, I would love to hear it, because I am also pretty sure that people can edit hidden fields Quote Link to comment Share on other sites More sharing options...
Pikachu2000 Posted August 5, 2010 Share Posted August 5, 2010 You'd either pass it through a hidden field, or a $_SESSION var. Also, you don't want to use action="<?php echo $_SERVER['PHP_SELF']; ?>" to submit a form to itself. Use action="" instead. Quote Link to comment Share on other sites More sharing options...
fortnox007 Posted August 5, 2010 Author Share Posted August 5, 2010 Wow thanks a lot for your swift response. Would you mind explain a little why not to use <?php echo $_PHP['PHP_SELF']; ?> I am just starting with php and in the book I bought they say i should use it to let the page self reference. Is there maybe a security risk when i use it? If you happen to have time for it i would be extremely pleased. Ill search for session variables (just 3 chapters away ;-) Thanks man!

fortnox007 Posted August 5, 2010 Author Share Posted August 5, 2010 Holy crap, I just googled my ass of for don't use <?php $_SERVER['PHP_SELF']; ?> and i found loads and loads of blogs about it. Thanks Alot for pointing me to this. I really apreciate it The only thing i realy hate is that the book i have doesn't say 1 word about it and above all a so called security dude was one of the authors. Well if someone knows a good book to write proper and secure php I am all ears! (eyes in this case ) And again thanks m8 for the quick help Quote Link to comment Share on other sites More sharing options...
