立刻渲染view

$this->set('title_for_layout','提示');
$this->set('error', $errMsg);
$this->render('/Elements/ajax');
$this->response->send();
$this->_stop();

调试

在 controller 中设置debug级别为2

public function beforeFilter(){
		parent::beforeFilter();
		Configure::write('debug', 2);
	}

打印sql语句

debug($this->ModelName->getDataSource()->getLog(false, false)); exit;
#或者
ConnectionManager::getDataSource('default')->getLog(false, false);
#直接输出sql
ConnectionManager::getDataSource('default')->showLog();
#在model里可以这样写
$this->getDataSource()->showLog();

全局常量和方法

pr()
带<pre>标签的 print_r。 Convenience wrapper for print_r(), with the addition of wrapping <pre> tags around the output.

常用cakephp自带函数

Hash提取二维数组

$users = Array(
     Array(
        'user'=>Array('id' => 123,'name'=> 'fred','surname' => 'bloggs')
     ),
     Array(
        'user'=>Array('id' => 245,'name' => 'fred','surname' => 'smith')
     ),
     Array(
        'user'=>Array('id' => 356,'name' => 'joe','surname' => 'smith')
      )
   );
$ids = Hash::extract($users, '{n}.user.id');
// $ids will be array (123, 245, 356)
$ids = Hash::extract($users, '{n}.user[name=fred].id');
// $ids will be array (123, 245)
$surname = Hash::get($users, '0.user.surname');
// bloggs

注意：{n}后面没有.
