weird issue with POST variable [IE/FF]

[supermars]

Hi all, I'm having a weird problem since in a simple "broken link reporting system" everything works fine with Firefox making the image appear when the page is first viewed while making the text "broken link reported" appear when you've clicked on the link. While with Internet Explorer it just doesn't work.. that means it just loads everytime the page without seeing the $_POST['bad_link'] set.
What can it be?
Thanks!! 🙂

<?php 
if (isset($_POST['bad_link'])){
 echo"<span>Broken link reported</span>"; //broken link reported
}else{
echo"<form method=\"post\" action=\"/current_page.php\" name=\"bad_link\"> <input type=\"image\" value=\"bad_link\" src=\"/img/cross.gif\" name=\"bad_link\">report broken link</form>";
	}
?>

Try

<?php
//use single quote is much neater and faster when there are no variables to echo. Remove / from before current_php.php and img/cross.gif

if (isset($_POST['bad_link'])){
	echo '<span>Broken link reported</span>'; //broken link reported
}else{
	echo '<form method="post" action="current_page.php" name="bad_link"> <input type="image" value="bad_link" src="img/cross.gif" name="bad_link">report broken link</form>';
}
?>

Thanks for you advice, I'll have to get use to single quotes since they make code much cleaner. Though unfortunately that didn't solve the problem so I just changed the "if" condition :

$_SERVER['REQUEST_METHOD']=='POST'

I tested it a bit and it seems working fine, I just hope it doesn't have any strange implication/problem.... since I think it should work like "if you get the page with a POST then report the broken link". Maybe I should put something like "&& referrer page== the page where the broken link is".
What do you think about it? 🙂

Ok, I added this to the check:

&& $_POST['referral_page_for_broken_link']==$_SERVER['REQUEST_URI']

where the variable contained in $POST['referral_page_for_broken_link'] comes from a

<input type=\"hidden\" name=\"referral_page_for_broken_link\" value=\"$_SERVER[REQUEST_URI]\">

so it's a sort of double check and seems working fine. Is it ok in your opinion? 😉
