今天要给各位朋友分享的是ZendFramework2连接数据库操作例子分享,为大家详细介绍了ZendFramework2连接数据库操作,结合完整实例形式分析了ZendFramework2连接数据库的具体步骤、配置方法、相关操作技巧以及注意事项,有兴趣的朋友赶紧来了解一下吧。
相对于zf1,zf2让我们觉得数据库的操作对于字段来说很简单,但是即使配置被写入,数据库的操作基本上也不需要移动,但它仍然比配置1更复杂或者那句话,每个人都可以看一下源代码。
Module.php 中添加
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
},
),
);
}
student.php 这个是Model/Student.php
namespace Student\Model;
class Student
{
public $id;
public $name;
public $phone;
public $mark;
public $email;
public function exchangeArray($data)//别名
{
$this->id = (!empty($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;
}
}
StudentTable.php Model/StudentTable.php
<?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)
{//分页
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/IndexController.php 调用数据库
public function indexAction(){
/* return new ViewModel(array(
'students' => $this->getStudentTable()->fetchAll(), //不分页
));*/
$page=$this->params('page');//走分页 在model.config.php里面设置:
/* model.config.php
'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' => $paginator //模板页面调用的时候的名字
));
//print_r($this->getStudentTable()->fetchAll());
}
在模板页面的调用
<?php foreach ($this->paginator as $student) : ?>
<tr id="<?php echo $this->escapeHtml($student->id);?>">
<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>//应用了在Student.php的别名
<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;?>
