PHP 5 and isset()?

I have a script that works fine on PHP 4.

The function is a form that submits to itself and at the top
of the
page is below and the form has a submit button named
"submit button"

if(isset($_POST['submit_button'])){
}


The problem is that on PHP Version 4 the submit button works
fine and
the page goes into the if statement, however on PHP Version
5.1.2, the
value isn't recognized as being set.

I can echo the variable to the page and it will display but
is there
some known issue in PHP5 that might not be picking this up
or is there
an alternate way to code this? I have tried setting the
variable to a
local variable and also the GET method and still no joy.

Thanks
Bry

isset still works in PHP5.  make sure submit_button has a
value.  if it
doesn't (i.e., the submit button is rendered as default), it
may not be
getting sent over, similar to the way checkboxes aren't sent
unless
they are set to "on".

also, i'm sure you've done it, but make sure your form has a
method and
that it is set to post.

If i echo $_POST['submit_button'] it shows the assigned
value but it
wont go into the if statement for some reason.


<?
session_start();
include('functions.php');
$button_press = $_POST['del_image'];
if(isset($button_press)){
while (list ($key,$val) = each ($box)) {
$query = mysql_query("DELETE FROM images WHERE
image_path='$val'");
unlink($val);
}
}
checkLogin();
drawHeader();
?><br>
<br>
<br>
<center>
<form action="edit_images.php"
method="POST">
<table width="50%" border="1">
<tr>

</tr>
<?
include('db_connect.php');
$query = mysql_query("SELECT * FROM images ORDER BY
category ");

while($row = mysql_fetch_array($query)){

	echo "<tr
