HTTP_POST_VARS x y

[jimbo]

I have a form on one page with dynamically created form element names. Such as:
<input type="text" name="qty_<? print $i; ?>" value="0" size="8">

The form elements include a select box, a text input, and radio buttons. When the form is submitted and the next page loads, included in the HTTP_POST_VARS array are the keys x and y. Even more odd is that the values associated with these keys change each time the form is submitted, even if the form is left blank. They seem to range from x 50 to 70 to 7 13 to 18.

I do not have any form fields with the names x or y. Does anyone know why these are being added to the end of the array or what I can do to prevent this from happening? Thank you in advance for any help.

I'd be willing to guess that you are using an image as the submit button. In which case, the "x/y" variables you are seeing are the x/y co-ordinates of the exact point on the image that you clicked.

You were absolutely correct. It was the x/y coordinates of the point that was clicked on the submit image. Thank you so much for the quick response and helpful answer.
