how to set a value for Zend_Form_Element_Submit (zendframework 1)

Question

I have am having trouble setting the basic values of a zend form element submit button (Zendframework1). I basically want to set a unique id number in it and then retrieve this number once the button has been submitted.

Below is my code. you will nots that I tried to use the setValue() method but this did not work.

$new = new Zend_Form_Element_Submit('new');
  $new
   ->setDecorators($this->_buttonDecorators)
   ->setValue($tieredPrice->sample_id) 
   ->setLabel('New');

  $this->addElement($new);

I would also appreciate any advice on what I use to receive the values. i.e what method I will call to retrieve the values?

The label is used as the value on submit buttons, and this is what is submitted. There isn't a way to have another value submitted as part of the button as well - you'd either need to change the submit name or value (= label).

What you probably want to do instead is add a hidden field to the form and give that your numeric value instead.

It's a little bit tricky but not impossible :

You need to implement your own view helper and use it with your element.

At first, you must add a custom view helper path :

How to add a view helper directory (zend framework)

Implement your helper :

class View_Helper_CustomSubmit extends Zend_View_Helper_FormSubmit
{
    public function customSubmit($name, $value = null, $attribs = null)
    {
        if( array_key_exists( 'value', $attribs ) ) {
            $value = $attribs['value'];
            unset( $attribs['value'] );
        }

        $info = $this->_getInfo($name, $value, $attribs);
        extract($info); // name, value, attribs, options, listsep, disable, id
        // check if disabled
        $disabled = '';
        if ($disable) {
            $disabled = ' disabled="disabled"';
        }

        if ($id) {
            $id = ' id="' . $this->view->escape($id) . '"';
        }

        // XHTML or HTML end tag?
        $endTag = ' />';
        if (($this->view instanceof Zend_View_Abstract) && !$this->view->doctype()->isXhtml()) {
            $endTag= '>';
        }

        // Render the button.
        $xhtml = '<input type="submit"'
                . ' name="' . $this->view->escape($name) . '"'
                        . $id
                        . ' value="' . $this->view->escape( $value ) . '"'
                                . $disabled
                                . $this->_htmlAttribs($attribs)
                                . $endTag;

        return $xhtml;
    }

}

So, you assign the helper to the element :

$submit = $form->createElement( 'submit', 'submitElementName' );
$submit->setAttrib( 'value', 'my value' );  
$submit->helper = 'customSubmit';
$form->addELement( $submit );

This way, you can retrieve the value of the submitted form :

$form->getValue( 'submitElementName' );

What would be the advantage of this approach over using the built in $new->setLabel() method?

Alexandre Brach Over a year ago

You're right, it would be better to use setLabel instead of setAttrib( 'customLabel' ) (and in the helper, $this->_label instead of $attribs['customLabel'])

hi alex and Tim. i am totally confused wiht Alex solution-and Tim subsequent comment. Is Alex saying that it is indeed possible to make a custom submit button. if so, what is the customSubmit method for; is that for receiving the values or for creating the button.

Alexandre Brach Over a year ago

Andreea, I've just edit my code and I have tested it : it allow you to get the submitted value , even if I don't really understand why do you need this behavior. With this method, I don't know how to use $form->setValue() directly, you have to use $form->setAttib( 'value', 'XXX' ). You don't have to call the customSubmit method yourself, all you need is in my response

Tim Fountain Over a year ago

My point was, as far as I can see this helper doesn't add anything that can't be done with the formSubmit helper built into ZF. You can already set the submit button's value (just slightly confusingly using setLabel()). But this doesn't really help the OP since she's wanting to submit a numeric value with the button (probably not something you'd want to show to the user).
