Why won't my flash message show? (Cake PHP 2.0)

Question

In AppController:

public $helpers=array("Session","Html","Form");
public $components = array(
    'Session',
    'Auth' => array(
        'loginRedirect' => array('controller' => 'MainPages', 'action' => 'home'),
        'logoutRedirect' => array('controller' => 'MainPages', 'action' => 'front')
    )
);

In MainPagesController:

public function front()
{

    $this->Session->setFlash('Your stuff has been saved.');
    debug($this->Session->read('Message'));
    //etc...

In default layout (default.ctp)

<div id="content">
    <?php echo "Flash:" ?>
    <?php echo $this->Session->flash(); ?>

The correct flash message shows in the debug but not on the view. What am I missing? PS It's not because of space after the ?>.

Edit: I have discovered that CakePHP is calling the session helper before the session component for some reason. Still trying to figure out how to fix it.

Answer 1

创建flash消息的简单方法是在app / view / element目录中创建ctp文件

Answer 2

Try

<div id="content">
    <?php echo "Flash:" ?>
    <?php echo $this->Session->flash('auth'); ?> 
    <?php echo $this->Session->flash(); ?>

You need to define flash('auth') in your view to see 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') ?>

Answer 4

I think it is because you have an error here:

<?php echo "Flash:" ?>

You are missing the semi-colon

<?php echo "Flash:"; ?>
