If you give each submit button a different name you can check which one was pressed using the isset function:

PHP Code:

---

if (isset($_POST['delete'])) {
    /* do delete */
} else if (isset($_POST['change'])) {
    /* do change */
}

Ok Thanks I Assume That U Don't Have An Answer How To Do It Only With Js.
And What About My Other Section Of The Question?
Tnx

And the other part to your question is? This is the PHP forum but why use Javascript to deal with a submitted form? The whole point of submitting the form is to send the data back to the server. :confused:

i think that u r wrong why should i spend resources if i can do it on the client side?:-)

Do what exactly, on the client side. It's very hard to get things right when you are being so vague.

you can create 2 forms using javascript with different actions.

have each button have an onClick event (or use an event handler which is the better way) and call a different function based on which button is pressed. Inside the function you can call the submit function of each form separately.

... and then your website will be absolutely useless to anyone who has javascript disabled.

either way, if you're not looking for a PHP solution, why did you post this in the PHP forums? we don't take kindly to doing things on the client side around these parts.
