<?php
include_once('session.egn');
if (isset($HTTP_POST_VARS['submit']))
if ( isset($HTTP_SESSION_VARS['done']) AND $HTTP_SESSION_VARS['done'] ==
$PHP_SELF)
{
echo "a <br>\n";
echo "You can only press submit once <br>\n";
exit();
} else
{
echo "b <br>\n";
$done = $PHP_SELF;
session_register('done');
}
// do some code
echo "
<form method='post' action='$PHP_SELF'>
<input type='hidden' name='submit' value ='1'>
<input type='submit'>
</form>
";
?>
try this, this allows you to load the page, press submit once, and not
again.
