how to set a value for Zend_Form_Element_Submit (zendframework 1) - zend-framework

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?

Answer 1

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 :

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' );
