multiple submit button

hello,

I'm using a form with 2 submit buttons and I want to know witch one was clicked on.
I found on google that you can use de methode isChecked(), but this always return false:

PHP Code:


			
$form->add->isChecked()

Someone how know what I'm doing wrong?

greets,

Without seeing the rest of your code, that's fairly difficult to say.

Quote:

isChecked() checks the submitted value against the label in order to determine if the button was used.

What do you have set as the name, value and label for your two buttons?

PHP Code:


			
$form = new Custom_forms_AddMenuItem();

PHP Code:


			
class Custom_forms_AddMenuItem extends Zend_Form {

    

public function __construct()  { 



// input box

  

$add = new Zend_Form_Element_Submit('add');

$add ->setLabel('Save item')

       ->setValue('Add');

             

$addOther = new Zend_Form_Element_Submit('addOther');

$addOther ->setLabel('Save and add other item')

           ->setValue('Add other');



$this->addElements(array($name, $parent, $contAction, $linkVar, $menuPerm, $add, $addOther));



// decorators

}



}

Believe it or not, this is actually much easier than it sounds.

If you have multiple submit buttons with the same name but different values, the form will automagically assign the value of the pressed button to that name.

So...

Code:

<FORM action="./" method="post">
<INPUT type="text" name="whatever">

<INPUT type="submit" name="formsubmit" value="one">
<INPUT type="submit" name="formsubmit" value="two">
<INPUT type="submit" name="formsubmit" value="three">
</FORM>

And....

PHP Code:


			
$submit = $this->_request->getPost('formsubmit');



switch($submit) {

case 'one':

   // button one was pressed

   break;

case 'two':

   //button two was pressed

   break;

case 'three':

   // button three was pressed

   break;

}



}

Sorry I'm not specifically using Zend_Form in my examples, I rarely use it myself. But, this is just an example.

One major disclaimer, however:

If you are submitting the form through an Ajax request, this may be iffy!!
I know for a fact that Prototype's Form.serialize() can't handle which one was pressed.
