$_POST not being recognized on submit of form in IE

rio38 · December 17, 2008

Sorry for the long example of code, but I have a form that displays and a submit button named "pass_submit". I check for isset($_POST['pass_submit'] when the form is submitted.

The logic works correctly in FF, but not in IE. The isset fails every time and I just get teh form displayed again. I check for the value of isset and get nothing.

<head>
<title></title>
<link rel="stylesheet" href="styles.css">
<style type="text/css">
<!--
.style1 {color: #FF0000}
-->
</style>

</head>
<body>
<?php

function imageResize($width, $height, $target) {

//takes the larger size of the width and height and applies the formula accordingly...this is so this script will work dynamically with any size image

if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}

//gets the new value and applies the percentage, then rounds the value
$width = round($width * $percentage);
$height = round($height * $percentage);

//returns the new sizes in html image tag format...this is so you can plug this function inside an image tag and just get the

return "width=\"$width\" height=\"$height\"";

}

?>

<?php
  	if(isset($_POST['pass_submit']))
  	{
	$username = $_GET['user'];
	$pass = $_POST['promopassworddl'];

	mysql_connect("xx.xxx.xxx.xx", "xxxx", "xxxxxxx");
	mysql_select_db("xxxxxxx");

	$result = mysql_query("SELECT * FROM promo WHERE user_name = '" . $username . "'");
	$rs = mysql_fetch_array($result);
	if($rs['promopass'] == $pass)
	{
	  $imageResult = mysql_query("SELECT * FROM images WHERE user_name = '" . $username . "'");

	  {

in your form fields use id="name" as well as name="name" also change post to POST

I believe the problem exists because when you are on a form (in IE) and you hit enter rather then submit, it doesn't fire the submit button, it just sends the variables to the action script.

The fix for this is to add a hidden variable into your form, so no matter what happens (enter, return or submit button), 'pass_submit' is always sent.

Add this...

...underneath your <form> code.

Excellent! Worked like a charm. I appreciate the quick response. I guess I will have to modify all of my fomrs now.

Thanks.
