Which Submit Button was Clicked in CakePHP? Use Name.

If you want to have multiple submit buttons that make a form do different things there's a simple way to do this. The name of the submit button that was clicked by the user will be sent (via POST) with all the other POSTed data. This is very handy if you want to have a cancel button and continue button. In CakePHP the name of the button won't be in $this->data, but it's easy enough to get...

Give the Submit Button a Name

Show Plain Text

echo $form->submit('Checkout Now', array('name'=>'proceedToCheckout'));

If you don't provide a name for your submit button, when the user clicks the button, the form will simply submit. If you assign a name (and make sure it's unique) then you can determine which button was clicked by the user.

Find Out Which Button was Clicked

Show Plain Text

if(isset($this->params['form']['proceedToCheckout'])) {
    //user clicked the submit button named proceedToCheckout... so we'll do that
    $this->redirect(array('action' => 'checkout'));
}

Figuring out which button was clicked by the user is easy...just look in $this->params['form']['buttonName'] where buttonName is what you named your button. I just check to make sure it's isset() because the value doesn't matter.

That method works well when I'm using simple $form-submit(), but when I try to do it using $ajax->submit(), or $ajax->form() (... ) $form->submit, my $this->params['form'] is always empty.

I'm already saying ajax to use POST.

Thank you
