[TYPO3-core] RFC: Mailform doesn't work with image submit buttons #1374

[Ingmar Schlecht]

This is a CVS patch request.

Problem:
Mailforms don't work with <input type="image"> submit buttons.
This is because browsers don't send the value="..." attribute of image
buttons when the form is submitted. Instead, the x/y coordinates are sent.

Example:
   An image button like this:
         <input type="image" name="mybutton" src="test.jpg" />
   ...results in GET variables like this:
         &mybutton.x=199&mybutton.y=114
   ...which result in a PHP $_GET array like this:
         Array (
             [mybutton_x] => 199
             [mybutton_y] => 114
         )

Solution:
Check for the _x and _y variables as well.
