PHP - Detecting whether the page was just submited to..

asbo · Mar 23, 2004

hey --

I'm trying to detect whether or not the page was just submitted to, and if it was, display something, and if it wasn't display a form to submit to it. Here's the code I have so far:

Code:

<html><body>
<br><center>
<table style="border: 2px red;" cellpadding="5"><tr><td>
<font face="tahoma" size="1">

<?php
if ($submit) {
  echo "You just submited the form!";
} else {
?>
  <form method="post" action="<?php echo $PHP_SELF ?>">
  First Field:&nbsp;<input style="font-family: verdana, arial, "ms sans serif", sans-serif; font-size: 8pt; color: #000000; background-color: #ffffff; border: 1 solid #000000;" type="text" name="first"><br>
  Second Field:&nbsp;&nbsp;&nbsp;<input style="font-family: verdana, arial, "ms sans serif", sans-serif; font-size: 8pt; color: #000000; background-color: #ffffff; border: 1 solid #000000;" type="text" name="second"><br><br>
  <center><input style="font-family: verdana, arial, "ms sans serif", sans-serif; font-size: 8pt; color: #000000; background-color: #ffffff; border: 1 solid #000000;" type="Submit" name="submit" value="Do it!"><center>
  </form>
<?php } ?>

</td></tr></table></center>
</body></html>

I'm really new to PHP; can someone tell me what I'm doing wrong, and possibly point me to a good beginners tutorial as well?

Thanks,

..I found an excellant page for forms and outside variables in PHP on the PHP.NET site that eluded my previous searches for whatever reason, but thought I'd share .. :here:

I check like so:

PHP:

if( $_POST['submit'] && $_POST['submit'] != "" ) {
// then the form was posteed
}
else
 // it was not

That's a lot simplier than I found; I used a hidden form element that was called submitted or something, and then just checked whether it equaled the right thing or not.

Thanks!
