Question

I have a form that contains multiple submit buttons. How can I pass a parameter submitting the form to find out which submit has been pressed? No JavaScript allowed.

Answer 1

Assuming you have 2 or more buttons like this:

<input type="submit" name="SubmitButtonOne" value="Button One"/>
<input type="submit" name="SubmitButtonTwo" value="Button Two"/>

Check for the names of the buttons, in the submitted (POST) data.

In PHP for example, that would be:

if (isset($_POST['SubmitButtonOne'])){
    //Do something.
}elseif (isset($_POST['SubmitButtonTwo'])){
    //Do something.
}

Or, check for the submitted values:

<input type="submit" name="formSubmit" value="Button One"/>
<input type="submit" name="formSubmit" value="Button Two"/>

switch ($_POST['formSubmit']) {
    case 'Button One':
        //Do something.
        break;
  case 'Button Two':
        //Do something else.
        break;
}
