Of couse I have an echo $_POST['register']; to see if the name attribute is being passed.

 

<html>
<head>
<title>Register for FREE Shopping Cart</title>
<link href="style_sheet.css" rel="stylesheet" media="screen">
</head>
<body>
<table align="center">
<tr>
<td>
<fieldset><legend>Register Here</legend>
<table>
<tr>
	<td>
<form action="register.php" method="post">
	<table>
		<tr>
			<td>
			Username:
			</td>
			<td>
			<input type="text" id="username" name="username" size="32" value="<?php if(isset($_POST['username'])){echo $_POST['username'];}?>" />
			</td>
		</tr>
		<tr>
			<td>
			Password:
			</td>
			<td>
			<input type="password" id="password" name="password" size="32" value="" />
			</td>
		</tr>
		<tr>
			<td>Re-password:
			</td>
			<td><input type="password" id="password_confirmed" name="password_confirmed" size="32" value="" /></td>
		</tr>
		<tr>
			<td>Email:
			</td>
			<td><input type="text" id="email" name="email" size="32" value="<?php if(isset($_POST['email'])){echo $_POST['email'];}?>" /></td>
		</tr>
		<tr>
			<td colspan="2" align="center" class="style7">
			You must confirm the email address before activating your account.
			</td>
		</tr>
		<tr>
			<td colspan="2" align="center">
			<input type="image" src="/images/registermyaccount.gif" value="register" name="register"/>
			</td>
		</tr>
	</table>
</form>
	</td>
</tr>
</table>
</fieldset>
</td>
</tr>

We need to see the script that processes the form data, i.e. register.php

 

It's NOT $_POST['register'].  It's either $_POST['register_x'] or $_POST['register_y']. Image submits work like image maps - they give the x and y coordinates of where the image was clicked relative to the top left corner.

o snap. I don't know anything about maps. is there a good tutorial to learn from. I thought it worked just like 'button' and 'submit'.

 

My script doesn't do anything until the $_POST['register'] is set. I.E. if (isset($_POST['register'])) { //run the script }

 

so basically i need to change the $_POST['register_x'] or $_POST['register_y']?

Then you have a logic or database problem with the code that follows.  Checking that an image button is clicked requires you verify that either an x or y coordinate has been passed.  That x and y stuff is actually the same basis that makes an html image map detect where it's been clicked.
