btherl Posted June 23, 2008 Share Posted June 23, 2008 For that to work you will need to have register_globals on, and you will need to have your submit button named "submit", all lowercase. And the form must have been submitted by clicking that submit button, not via a javascript submit() call.

DarkWater Posted June 23, 2008 Share Posted June 23, 2008 btherl, you just made register_globals sounds like a beneficial thing. Let me clarify. You would need register_globals on for that to work as-is, but seeing as register_globals is an epic failure, don't use them and just do $_POST['submit'].

redarrow Posted June 23, 2008 Share Posted June 23, 2008 do it this way or the high way register_globals on is bad programming now and turned off on php6 <?php if(isset($_POST['submit'])){ what_ever } ?> Link to comment https://forums.phpfreaks.com/topic/111413-submit-value-is-empty/#findComment-571878 Share on other sites More sharing options...
DarkWater Posted June 23, 2008 Share Posted June 23, 2008 @redarrow: They aren't turned in in PHP6, they're turned off in PHP since 4.2... They're COMPLETELY REMOVED in php6.

btherl Posted June 23, 2008 Share Posted June 23, 2008 Given how long it's taken for web hosts to switch to php 5, I don't think there's any danger of register_globals going missing anytime soon And no I am not endorsing register_globals by that statement. $_POST['submit'] is better (or $_GET['submit'] if you're using a get form, but you should be using a post form if possible) Link to comment https://forums.phpfreaks.com/topic/111413-submit-value-is-empty/#findComment-572067 Share on other sites More sharing options...
