[英]Why won't my flash message show? (Cake PHP 2.0)
在AppController中:
public $helpers=array("Session","Html","Form");
public $components = array(
'Session',
'Auth' => array(
'loginRedirect' => array('controller' => 'MainPages', 'action' => 'home'),
'logoutRedirect' => array('controller' => 'MainPages', 'action' => 'front')
)
);
在MainPagesController中:
public function front()
{
$this->Session->setFlash('Your stuff has been saved.');
debug($this->Session->read('Message'));
//etc...
在默認布局中(default.ctp)
<div id="content">
<?php echo "Flash:" ?>
<?php echo $this->Session->flash(); ?>
正確的閃存消息顯示在調試中,但不顯示在視圖上。 我錯過了什么? PS這不是因為?>之后的空間。
編輯:我發現CakePHP由於某種原因在會話組件之前調用會話助手。 仍在試圖弄清楚如何解決它。
創建flash消息的簡單方法是在app / view / element目錄中創建ctp文件
嘗試
<div id="content">
<?php echo "Flash:" ?>
<?php echo $this->Session->flash('auth'); ?>
<?php echo $this->Session->flash(); ?>
您需要在視圖中定義flash('auth')
以查看authentication session flash messages.
My setflash works in this way..
Keep this in the App controller
function setFlash($message, $type = 'blue') {
//what ever the color you need..
$arr = array('red' => 'red', 'green' => 'green', 'yellow' => 'yellow', 'gray' => 'gray', 'blue' => 'blue');
$this->Session->setFlash($message, 'default', compact('class'), $arr[$type]);
}
and then call it from the controller action where you need to make the flash message as below..
$this -> setFlash("This is flash message","red");
now you need to make the flash in the layout(if you are using) or in your ctp file..
<?php echo $this->Session->flash() ?>
<?php echo $this->Session->flash('red') ?>
我想是因為你在這里有錯誤:
<?php echo "Flash:" ?>
你錯過了分號
<?php echo "Flash:"; ?>
