ZendFramework2连接数据库操作实例

2024-02-25 12:17:09 50

本文实例讲述了ZendFramework2连接数据库操作。分享给大家供大家参考，具体如下：

相对于zf1,来说,zf2让我们对于数据库这方面的操作我的个人感觉是对于字段起别名简单了,但是对数据库的操作虽然配置写好的就基本不需要动了，但是还是比1的配置要繁琐,

还是那句话，大家可以去看看源码。。。

Module.php里面添加

publicfunctiongetServiceConfig()
{
returnarray(
'factories'=>array(
'Student\Model\StudentTable'=>function($sm){
$tableGateway=$sm->get('StudentTableGateway');
$table=newStudentTable($tableGateway);
return$table;
},
'StudentTableGateway'=>function($sm){
$dbAdapter=$sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype=newResultSet();
$resultSetPrototype->setArrayObjectPrototype(newStudent());
returnnewTableGateway('cc_user',$dbAdapter,null,$resultSetPrototype);//tableNameiscc_user
},
),
);
}

student.php这个是Model/Student.php

namespaceStudent\Model;
classStudent
{
public$id;
public$name;
public$phone;
public$mark;
public$email;
publicfunctionexchangeArray($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.phpModel/StudentTable.php

tableGateway=$tableGateway;
}
publicfunctionfetchAll($paginated)
{//分页
if($paginated){
//createanewSelectobjectforthetablealbum
$select=newSelect('cc_user');
//createanewresultsetbasedontheStudententity
$resultSetPrototype=newResultSet();
$resultSetPrototype->setArrayObjectPrototype(newStudent());
//createanewpaginationadapterobject
$paginatorAdapter=newDbSelect(
//ourconfiguredselectobject
$select,
//theadaptertorunitagainst
$this->tableGateway->getAdapter(),
//theresultsettohydrate
$resultSetPrototype
);
$paginator=newPaginator($paginatorAdapter);
return$paginator;
}
$resultSet=$this->tableGateway->select();
return$resultSet;
}
publicfunctiongetStudent($id)
{
$id=(int)$id;
$rowset=$this->tableGateway->select(array('id'=>$id));
$row=$rowset->current();
if(!$row){
thrownew\Exception("Couldnotfindrow$id");
}
return$row;
}
publicfunctiondeleteStudent($id)
{
$this->tableGateway->delete(array('id'=>$id));
}
publicfunctiongetLIValue(){
return$this->tableGateway->getLastInsertValue();
}
}

Student/IndexController.php调用数据库

publicfunctionindexAction(){
/*returnnewViewModel(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);
//setthecurrentpagetowhathasbeenpassedinquerystring,orto1ifnoneset
$paginator->setCurrentPageNumber((int)$this->params()->fromQuery('page',$page));
//setthenumberofitemsperpageto10
$paginator->setItemCountPerPage(10);
returnnewViewModel(array(
'paginator'=>$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

paginatoras$student):?>
escapeHtml($student->id);?>">
escapeHtml($student->id);?>
escapeHtml($student->name);?>
escapeHtml($student->phone);?>
escapeHtml($student->email);?>//应用了在Student.php的别名
escapeHtml($student->mark);?>
