[Resolved] Where's the cursor

[gordon7]

I have a form with an image contained inside.

<form method="post" action="phpscript.php">
<input type="image" name="picture" src="mypix.jpg" />
</form>

The image, in this case, works like a submit button. When activated, the name/value pair is sent - all is fine. However, I want to capture where the cursor is located over the image. This is also sent as name.x for the x-coord and name.y for the y-coord. When I use $_POST[name.x] to get the information, I get a convenient error message instead.

How do I get the cursor location information?

Thanks,
Gordon

ive never done what your saying so not too sure, but, your image is called picture NOT name.

i would have a look at $_POST['picture'] first, see what that contains.

Aye - they'd be in $POST['picture_x'] and $POST['picture_y']

Thanks guys, that did it.

However, I am confused. The data coming out of the form is in the name.x and name.y format. It seems counterintuitive to replace the "." with "_". It that a quirk here, or is endemic within php?

It's a php thing. It also puts in underscores for spaces in form object names - I think.

The spaces and dots are replaced by php with underlines because they aren't legal characters in variable names. So if you, assumedly for a good reason, had register_globals on, the name attribute would translate to a valid variable name.
