ZendFramework2 connection database operation example

This article describes the ZendFramework2 connection database operation. Share it for your reference, as follows:

Compared with zf1, zf2 makes us feel that it is simple to alias the fields, but although the database operation is basically not necessary to be moved, it is still more complicated than the configuration of 1.

The same goes, you can check the source code. . .

Add it inside

public function getServiceConfig()
{
    return array(
      'factories' => array(
        'Student\Model\StudentTable' => function($sm) {
          $tableGateway = $sm->get('StudentTableGateway');
          $table = new StudentTable($tableGateway);
          return $table;
        },
        'StudentTableGateway' => function ($sm) {
          $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
          $resultSetPrototype = new ResultSet();
          $resultSetPrototype->setArrayObjectPrototype(new Student());
          return new TableGateway('cc_user', $dbAdapter, null, $resultSetPrototype);//table Name is cc_user
        },
      ),
    );
}

This is a Model/

namespace Student\Model;
class Student
{
  public $id;
  public $name;
  public $phone;
  public $mark;
  public $email;
  public function exchangeArray($data)//Alias  {
    $this->id   = (!empty($data['cc_u_id'])) ? $data['cc_u_id'] : null;
    $this->name = (!empty($data['cc_u_name'])) ? $data['cc_u_name'] : null;
    $this->phone = (!empty($data['cc_u_phone'])) ? $data['cc_u_phone'] : null;
    $this->mark = (!empty($data['cc_u_mark'])) ? $data['cc_u_mark'] : null;
    $this->email = (!empty($data['cc_u_email'])) ? $data['cc_u_email'] : null;
  }
}

Model/

<?php
namespace Student\Model;
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\TableGateway\TableGateway;
use Zend\Db\Sql\Select;
use Zend\Paginator\Adapter\DbSelect;
use Zend\Paginator\Paginator;
class StudentTable
{
  protected $tableGateway;
  protected $table='cc_user';
  public function __construct(TableGateway $tableGateway)
  {
    $this->tableGateway = $tableGateway;
  }
  public function fetchAll($paginated)
  {//Pagination     if($paginated) {
      // create a new Select object for the table album
      $select = new Select('cc_user');
      // create a new result set based on the Student entity
      $resultSetPrototype = new ResultSet();
      $resultSetPrototype->setArrayObjectPrototype(new Student());
      // create a new pagination adapter object
      $paginatorAdapter = new DbSelect(
        // our configured select object
        $select,
        // the adapter to run it against
        $this->tableGateway->getAdapter(),
        // the result set to hydrate
        $resultSetPrototype
      );
      $paginator = new Paginator($paginatorAdapter);
      return $paginator;
    }
    $resultSet = $this->tableGateway->select();
    return $resultSet;
  }
  public function getStudent($id)
  {
    $id = (int) $id;
    $rowset = $this->tableGateway->select(array('id' => $id));
    $row = $rowset->current();
    if (!$row) {
      throw new \Exception("Could not find row $id");
    }
    return $row;
  }
  public function deleteStudent($id)
  {
    $this->tableGateway->delete(array('id' => $id));
  }
  public function getLIValue(){
    return $this->tableGateway->getLastInsertValue();
  }
}

Student/ Call database

public function indexAction(){
    /* return new ViewModel(array(
       'students' => $this->getStudentTable()->fetchAll(), //No page pagination
     ));*/
    $page=$this->params('page');//Go to the page to set it in:/*
'defaults' => array(
 'controller' => 'Student\Controller\Index',
 'action'   => 'index',
 'page'=>'1',
),
*/
    $paginator = $this->getStudentTable()->fetchAll(true);
    // set the current page to what has been passed in query string, or to 1 if none set
    $paginator->setCurrentPageNumber((int)$this->params()->fromQuery('page', $page));
    // set the number of items per page to 10
    $paginator->setItemCountPerPage(10);
    return new ViewModel(array(
      'paginator' => $paginator //The name of the template page when calling    ));
  //print_r($this->getStudentTable()->fetchAll());
}

Calling on the template page

<?php foreach ($this->paginator as $student) : ?>
<tr >
  <td><?php echo $this->escapeHtml($student->id);?></td>
  <td><?php echo $this->escapeHtml($student->name);?></td>
  <td><?php echo $this->escapeHtml($student->phone);?></td>
  <td><?php echo $this->escapeHtml($student->email);?></td>//The alias applied  <td><?php echo $this->escapeHtml($student->mark);?></td>
    <td><a href='#'  class='icol-bandaid editUserInfo'></a>  
      <a href='#' class='icol-key changePwd'></a>  
      <a herf='#'  class='icol-cross deleteStud'></a>
    </td>
  </tr>
<?php endforeach;?>
