Question

i have a web form who send post variables like:

<form action="teacher.php" method="post">
<input name="pass" type="password">
<input name="quiere" type="image" value="submit" src="IMG/unlock-32.png" />
</from>

In the same page i check for a submit acction with php doing a simple isset check like:

“if (isset($_POST[‘quiere’])) {“

But if you do this in IE the post var “QUIERE” (the button var) does not post, the others vars are fine, and if you try this simple form in any other browser it works. I only get this form function well in IE changing the button for a normal button, instead of a image button like:

<input name="quiere" type="submit" value="submit" />

In this way, the var “quiere” get post. So, what do you think? and sorry for my english.

Answer 1

This is a known issue in IE6 and IE7. image inputs are not submitted with a form as you’d expect. It submits the cords instead and changes the field names with appending _x or _y . i’ve run into this several times in the past and found others have as well.

A fix is to check for $_POST['quiere_x'] or $_POST['quiere_y'] instead of just $_POST['quiere']
