Zend Framework: Multiple Check Box Handling

Here I will try to describe how to handle multiple check box with Zend Form

Below is the Form from/user.php
<?php
class Form_User extends Zend_Form
{
    public function __construct($options = null)
    {
        parent::__construct($options);
      
        $this->setName('User_Form');
       
        $user_id = new Zend_Form_Element_Text('user_id');
        $user_id->setLabel('User ID')
                  ->setRequired(true)
                  ->addValidator('NotEmpty');

      
        ..................................
        ....................................
        ....................................

        $area = array(

                            'index' => 'Home Page',
                            'admin' => 'Admin Home',
                            'agent' => 'Agent Contorl',
                            'user' => 'User Contorl',
                            'cdist' => 'Card Distribution',
                            'cardsell' => 'Card Sell',
                            'manualmt' => 'Manual Money Transfer',
                            'moneydelivery' => 'Money Delivery',
                            'transactionmonitor'    => 'Transaction Moniitor',
                            'adminreport'   =>  'Admin Report',
                            'agentreport'   =>  'Agent Report',
                            'customercare'   =>  'Customer Care',

);

$privileges = new Zend_Form_Element_MultiCheckbox('privileges');

$privileges->setLabel("Select Previliges");
            foreach($area as $prev => $p)
            {
                $privileges->addMultiOption($prev,$p);
            }

        $user_photo = new Zend_Form_Element_File('user_photo');
        $user_photo->setLabel('Photo');
        $submit = new Zend_Form_Element_Submit('submit');
        $submit->setLabel('Save Data')
                 ->setAttrib('class', 'button')
        ;
       
         $this->addElements(array(
                $user_type,
                $agent_id,
                $user_id,
                .........
                $privileges,
                $submit));

    }
}


Now The Controller UserController.php


class UserController extends Zend_Controller_Action
{

    public function init()
    {
     /    }

       public function addAction()
    {
        // action body
       
        $this->view->headTitle('Add New User', 'PREPEND');
        $form = new Form_User();
        $this->view->form = $form;
      
        if ($this->getRequest()->isPost()) {
       
        $formData = $this->getRequest()->getPost();
        if ($form->isValid($formData)) {
        //$sp = implode(",",$privileges);
        $user_photo = ($form->getValue('user_photo')) ? $form->getValue('user_photo') : "";

        $data = array(
            'user_type' => $form->getValue('user_type'),
            'agent_id' => $form->getValue('agent_id'),
            'user_id' =>strtolower($form->getValue('user_id')),
           ..............................
.................................
            'privileges' => serialize($form->getValue('privileges')),
            'user_status' => $form->getValue('user_status'),
            'user_photo' => $user_photo,
        );

      
        $user = new Model_DbTable_Userinfo();

        $user-> addUser($data);
        $this->_redirect('/user/');

        } else {
            print_r($formData);
            $form->populate($formData);
        }
        }
    }



The Model to Do the database action

class Model_DbTable_Userinfo extends Zend_Db_Table_Abstract
{
    protected $_name = 'user_info';

       public function addUser($data)
    {
       
        $this->insert($data);
    }
}









To edit the Multiple check box value do as follows in Edit action

public function editAction()
    {
        // action body
        $sess = new Zend_Session_Namespace('uri');

        $this->view->title = "Edit User";
        $this->view->headTitle($this->view->title, 'PREPEND');
        $form = new Form_User();
        //$form->user_id->setAttrib('readonly','true');
        $form->removeElement('user_id');
        $user_id = new Zend_Form_Element_Hidden('user_id');
        $form->addElement($user_id);
        $this->view->form = $form;

        if ($this->getRequest()->isPost()) {
        $formData = $this->getRequest()->getPost();
        if ($form->isValid($formData)) {
        $user_id = $form->getValue('user_id');
        $agent_id = $form->getValue('agent_id');
        $user_photo =  $form->user_photo->getFileName('user_photo',false);

        if(!empty($user_photo))
            {
        $data = array(
            'user_type' => $form->getValue('user_type'),
            'agent_id' => $form->getValue('agent_id'),
            'user_pass' => $form->getValue('user_pass'),
            'user_name' => $form->getValue('user_name'),
            'user_address' => $form->getValue('user_address'),
            'user_contact' => $form->getValue('user_contact'),
            'user_email' => $form->getValue('user_email'),
            'privileges' => serialize($form->getValue('privileges')),
            'user_status' => $form->getValue('user_status'),
            'user_photo' => $form->getValue('user_photo'),
        );
            }
    else
        {
        $data = array(
            'user_type' => $form->getValue('user_type'),
            'agent_id' => $form->getValue('agent_id'),
            'user_pass' => $form->getValue('user_pass'),
            'user_name' => $form->getValue('user_name'),
            'user_address' => $form->getValue('user_address'),
            'user_contact' => $form->getValue('user_contact'),
            'user_email' => $form->getValue('user_email'),
            'privileges' => serialize($form->getValue('privileges')),
            'user_status' => $form->getValue('user_status'),
        );
        }
        $user = new Model_DbTable_Userinfo();
        $user->updateUser($data,$user_id);
        $this->_redirect($sess->req_uri);
        } else {
        $form->populate($formData);
        }
        }
        else {
        $user_id = $this->_getParam('user_id', 0);
        $user = new Model_DbTable_Userinfo();
        $user_data = $user->getUser($user_id);
        $form->populate($user_data);
        $prev = unserialize($user_data['privileges']);
        $form->privileges->setValue($prev);
        }
    }





Hope Thats help you.

  2. I find this post both interesting and a little bit confusing because I when I read the code it made me think there is a solution to my web development problem regarding my website but at the same time when I look at the website seeing the code for a long time sometimes gets me confused...
