[michalopek100]

maybe this is solution but I don't know how to do that,
my problem is:
I want to have confirm message when I click delete in form to delete row 1 in table. Now when I click cancel or no delete is submited. I want to do this in that way that when cancel form is not submitted
How?

Give the various submit buttons different names. Then in PHP you can see which one was clicked by seeing which $_POST['button name'] variable is set.

first you build your javascript function like this:

<script language="javascript">
function Confirm_Delete() {
 if (confirm("Are you sure you want to delete this?")) {
    return true;
 } else {
    return false;
 }
}
</script>

then make you link like this:

<a href="page.php" OnClick="return Confirm_Delete();">delete</a>

this will not allow the form to be submitted unless the confirm box has been aswered 'yes'. (providing javascript is enabled)

be careful that it doesn't. Remember that javascript is client side and php is server side.

Using a confirm button like this may execute other scripts on the page before you want them to.
