Many submit images

[majax]

Hi,
I ve a form which can be submitted by many different images, and i want to know
which one has been used, here is the code :
<FORM action="index.php?id=verif" method="POST" name="search" >
........
<input type="image" src="images/alert1.gif" name="valid[0]" value="Valider" border="0">
<input type="image" src="images/alert2.gif" name="valid[1]" value="Valider" border="0">
</form>

And the target file :

if (isset($_post['valid[0]') {
.........}
else {
........}

but it doesn't work, even with $post['valid_x[0]'] instead of $post['valid[0]'].

Any clue welcome

Thanks

$post is not right, you need to use $POST. PHP is case sensitive with variable names.

If that is not enough to fix it, you may need to number the elements yourself, not as an array. Like this:

valid_0
valid_1
valid_2

Then use:
if (isset($_POST['valid_0_x'])) { ... }
