image submit buttons

[Anon]

How I can test what submit image is clicked in my form?

<form action="mypage.php" >
<input type=image name="yes" value="yes" src="images/yes.gif">
<input type=image name="no" value="no" src="images/no.gif">
</form>

I try test isset($yes), but not $yes or $no params exists.

I tried name the submit images to identical name and test the value, it didn't work too.

Not too sure that I understand exactly what you are doing but I asume that you want to use an image as a submit button. Am I right??
If I am then it is quite easy to do. as is finding which image is clicked. but you will need to use some javascript, for the method I know.

what you do is put something like.

<FORM action="mypage.php" name="form1">
<INPUT type="hidden" name="picno" value="1">
<A href="#top" onclick="javascript:document.forms.form1.submit()"><IMG border=0 src="picture.jpg"></A>
</FORM>

<FORM action="mypage.php" name="form2">
<INPUT type="hidden" name="picno" value="2">
<A href="#top" onclick="javascript:document.forms.form2.submit()"><IMG border=0 src="picture.jpg"></A>
</FORM>

This will allow a user to click an image and the value in the hidden field is passed to the php script.

Mark.

Hey there,

Don't use all that Java just to do this simple task. PHP can do anything anyway, here is a solution for you, that is VERY simple:

<FORM ACTION="mypage.php" method="POST">
<input type=image name="yes" src="images/yes.gif">
<input type=image name="no" src="images/no.gif">
</form>

And then in your php script:

if($yes_x or $yes_y){
echo "You clicked yes!";
} elseif($no_x or $no_y){
echo "You clicked no!";
}

That is it!

Note that this works every time. However you may have to tweek the if() statements for php versions previous to php 4.0.6.

Anyway the values passes will always be $nameofbutton_x and $nameofbutton_y where $nameofbutton_x and $nameofbutton_y will be the numerical coordinates of the spot on the image where you clicked.

Hope that helped,
