Image button submit value

Image button submit value

For example, if you have a image button like

Code:

<input type="image" name="Submit" value='Register' class="btn" src="images/register_form_btn.jpg" />

When the form is submitted via POST. there is nothing for $_POST[’Submit’]. However, you will have $_POST[’Submit_x’] and $_POST[’Submit_y’] that records the x and y coordinates of the click.

You can not do

Code:

if($_POST['Submit_x'] ) {
  //do something
}

that’s because a user might press the Enter key to submit the form. In this case, $_POST[’Submit_x’] and $_POST[’Submit_y’] are both 0!!

A convenient solution is to put a hidden field such as

Code:

<input type='hidden' name='form_sent' value='1'/>

within the form. Then in your php code

Code:

if($_POST['form_sent'] ){
//process form
}
