2 submit buttons problem

yoki

Ok in my form, I have two submit buttons

Both of them are images.

1)
<input type="image" name="add_more_fields" src="images/add_more_fields.gif" alt="">

2)
<input type="image" name="Submit" src="images/continue.gif" alt="" tabindex="7">

If I replace the first input button with this <input type="button" name="add_more_fields">

the following condition in my PHP script is true:

if(isset($_POST['add_more_fields']))

else if I use this <input type="image" name="add_more_fields" src="images/add_more_fields.gif" alt="">

the condition is no longer true.

How come? Is this a PHP Bug? I would like to use an image instead of the plain button in my form. Please help someone! 🙁

Ok, now I'm really confused...

If I change the following condition:

if(isset($_POST['add_more_fields']))

if(isset($_POST['add_more_fields_x']))

It works fine...

I'm not sure if this is the right way...

I wanted to see what was posted so I did the following:
foreach (array_keys($_POST) as $p)
{ echo $p;
}

It echoed the following: add_more_fields_x and add_more_fields_y

Why is there 2 of them? Anyone can explain this?

add_more_fields_x and add_more_fields_y

This is very normal. You see the pupose of the input=image button was not for making custom buttons, but to submit x/y coordinates as POST values. This would be useful for maps ( I guess...never done it.) That's why you get a x and a y version of the same image button. You''l also notice if you do a print_r($POST), that you get different values for each. So I guess, the final answer is stick to the x appendage version.
