Images instead of buttons

[Anon]

Hi,

I'm trying to replace the good old Submit button on a form with an image.

My HTML is this:

<input type="image"
src="../images/ok_button.jpg" border="0"
name="submit">

The way that I understand this is that when the image is clicked, it should trigger the form action.

The PHP statement that I have at the beginning of the app is:

if(isset($submit)):

This should just check to see if the variable $submit is set.

However, it doesn't appear to be set as the required event never triggers.

What am I doing wrong?

Cheers,

Stuart

I would rather do something like

<input type="hidden" value="buttonpressed" name="go">

then at the beginning of the app do

if($go == "buttonpressed")
{
//do stuff
}
else
{
//do something else
}

If you use an image as a submit button, then what is passed to the program is a pair of variables imagename_x & imagename_y, that tell your program the coordinates of where the image was pressed (a holdover from image mapping).

You will have to check either the x or y value for non-zero values to see if the button was clicked.

You could also set a hidden form field in the HTML ( <input type="hidden" name="step" value="process"> )

then in the PHP,

switch ($step) {

case "process":
//do the processing
break;

default:
//do the default stuff
break;

}
