How to do this?

Anon

You know how when you hit a 'submit' button in a form, it can execute a php script? Well, I want to do the same thing, but with a graphical button that I made. It's just a .jpg file that I want to have execute a php script when clicked. Is this possible? If so, what would the code look like?

Thanks

I think you have two options here:

A. Check this site out:

B.
Put a normal picture-link (like you would do with any image) and make the link a JavaScript function. And put your PHP code within the JavaScript function. Never tried this myself but I think it should work.

if you use
<INPUT NAME="imgSubmit" TYPE="image" SRC="...">

you can't use (as you normally would)
if (isset($imgSubmit))
{
// form was sent
}

to test whether the form was sent,
because image-submit buttons don't sent their name as a value
but the x/y-position where you clicked on the image.
so, after submitting the form you have two values:
imgSubmit.x and imgSubmit.y
because the dot is a spacial char in php, it is converted to _

in php you get 2 vars
$imgSubmit_x and $imgSubmit_y

and your test looks something like this:
if (isset($imgSubmit_x))
{
// form sent
}

Thanks inter_joe for the work around on that 'dot' separating the var and X/Y! It was causing me some headaches, didn't know how to make php "see" that dot! 🙂

I think the problem is very easy .And i think you will modify your HTML code .Frist
you insert the code in your coresponding place as follows :
1 if you want a button
<form>
....
<input type = submit name ='submit'value='XXXXX...',action =yourfilename.php >
</form>

if you want a picture
as follows:
<a href=yourfiel.php ><src img= yourfilename.jpg></a>

if you want to pass some value you can insert some php program in the 2 html code !
