Pikachu2000 Posted June 25, 2010 Share Posted June 25, 2010 Please enclose PHP code in . . . tags.

Ninjakreborn Posted June 25, 2010 Share Posted June 25, 2010 <?php if ($_POST['submit'] == ''Add comment") { } ?> Also your Xhtml and PHP is malformed. Run the Xhtml through a validator. That might explain why it's being ignored instead of passing the variables. Proper form is important.

Pikachu2000 Posted June 26, 2010 Share Posted June 26, 2010 Do you have a different web browser you can use to try it? Maybe Firefox, or Opera? I'm starting to think the browser is choking because the script uses both $_POST and $_GET, and it worked fine here for me with Safari.

kindtiger Posted June 26, 2010 Author Share Posted June 26, 2010 I have tried Firofox and IE, both are not work. Everything works great, just the $_POST here is not work.

Pikachu2000 Posted June 26, 2010 Share Posted June 26, 2010 Paste this script into a new file, run it, and see what happens. If it works, there's a problem somewhere in the one you've been using. It could be a bad linefeed, or a control character, or even a word misspelled. If not, well, we'll cross that bridge if we get to it. <?php if( isset($_GET['get']) ) { echo "GET vars are: "; print_r($_GET); echo "<br /><br />"; } if( isset($_POST['submit']) ) { echo '$_POST[\'submit\'] is SET.<br />'; print_r($_POST); echo "<br /><br />"; } if( isset($_POST['hidden']) ) { echo '$_POST[\'hidden\'] is SET.'; } else { ?> <form action="?get=GetVarsAreSet" method="POST"> Enter a value here:<input type="text" name="one"><br /> Enter a different value:<input type="text" name="two" /><br /> <input type="hidden" name="hidden" value="hidden" /> <input type="submit" name="submit" value="Submit" /> </form> <?php } ?> Link to comment https://forums.phpfreaks.com/topic/205889-_postsubmit-is-not-work-thank-you-for-help/#findComment-1077576 Share on other sites More sharing options...
