Zend元素装饰器

Question

I created an element submit:

   $this->addElement('submit', 'button', array(
        'ignore'   => true,
        'label'    => 'Update',
        'class' => 'btn blue',
    ));

And now try to set for this element decorator:

    $submit = $this->getElement('submit');
    $submit->setDecorators(array(
        array('ViewHelper'),
        array('Description'),
        array('HtmlTag', array('tag' => 'div', 'class'=>'submit-group')),
    ));

Something is wrong in my code because I get fatal error that I call member function setDecorators on no object?

I think you either need to change:

$submit = $this->getElement('submit');

to

$submit = $this->getElement('button');

OR

$this->addElement('submit', 'button', array(
    'ignore'   => true,
    'label'    => 'Update',
    'class' => 'btn blue',
));

to

$this->addElement('submit', 'submit', array(
    'ignore'   => true,
    'label'    => 'Update',
    'class' => 'btn blue',
));

It appears the first parameter for addElement is the element type and the second parameter is the element id. Not the other way around.

And, getElement needs to take in that element id for it to work, not the element type
