You might notice X and Y values being submitted from your form, and you might be wondering where they came from! You will see them in the email you receive, like this:

X: 5
Y: 18

These are submitted from your form if you are using an image as a submit button as opposed to a conventional submit button. They are the x and y mouse coordinates of where the user clicked on the submit image and are sent by the browser.

If you do not wish to receive these values then you can choose to ignore them if using the Pro version of the script. If using the free version you will have to put up with them or change the image submit button on your form to a conventional submit button like this:

<input type="submit" value="Send">

If using the Pro version of the script you can ignore the values by entering them in the array of ignored fields. You will find instructions in the script about how to enable this and list the fields to ignore but in short you must enable it thus:

$ignore_fields = 1;

You must then include the x and y fields in the array of fields to ignore, like so:

$fields_to_ignore = array('x','y');

The above example is set up to ignore only the x and y inputs but in practise you might have other values in there too.

That's it, no more unwanted x and y inputs!

It should also be noted that these values (unless ignored) will allow an apparently blank form to be sent as PHP sees them as valid input, which effectively they are.
