发布评论后,我想显示消息:"您的评论已被接受审核".它出现在$ _SESSION数组中,但我该如何获取它？请帮忙.提前致谢.

Answer 1

这是你所有答案的组合.几乎任何块都适用于我:

    //A Success Message
    Mage::getSingleton('checkout/session')->addSuccess("Your cart has been updated successfully!");

    //A Error Message
    Mage::getSingleton('checkout/session')->addError("Your cart has been updated successfully!");

    //A Info Message (See link below)
    Mage::getSingleton('checkout/session')->addNotice("This is just a FYI message...");

    //These two lines are required to get it to work
    session_write_close(); //THIS LINE IS VERY IMPORTANT!
    $this->_redirect('checkout/cart');

信用归因于:

Answer 2

以下代码适用于我:

1. 设置消息控制器:

   Mage::getSingleton('customer/session')
       ->addSuccess(Mage::helper('mymodule')->__('Data saved.'));
   

2. 要在其中检索消息的控制器中的init消息:

   $this->loadLayout();
   $this->_initLayoutMessages('customer/session');
   $this->_initLayoutMessages('catalog/session');
   $this->renderLayout();`
   

3. 检索template(.phtml)文件中的消息:

   echo $this->getMessagesBlock()->getGroupedHtml();
   

Answer 3

$messages = Mage::getSingleton('core/session')->getMessages(true);
foreach($messages->getItems() as $message)
{
   // Do something   
   $message->getText();
}

Answer 4

看来你要求的东西已经存在于Magento中.一旦用户发布了有关产品的评论,默认情况下会显示"您的评论已被接受审核"消息,如app/code/core/Mage/Review/controllers/ProductController.php第188行所述(Magento 1.4. 0.1)

无论如何,如果你想显示消息(通知,成功,错误,警告),只需使用,例如在成功消息的情况下:

<?php
$message = $this->__('Your success message here');
Mage::getSingleton('core/session')->addSuccess($message);
?>

只要页面的模板文件具有$ this-> getMessagesBlock() - > getGroupedHtml()代码,该消息将存储在会话中并自动出现在前端,这是Magento附带的所有默认phtml页面中的情况.所以你真的不必费心.

当然,在上面的例子中,你可以改变

addSuccess($message)

通过 addError($message)或addWarning($message)或addNotice($message)依赖那种信息你要显示的.

Answer 5

由于消息存储在core子数组中，因此您将使用 Magento 核心消息块来检索它。在您的布局中，您应该能够看到这一行（在 page.xml 中）：

<block type="core/messages" name="global_messages" as="global_messages"/>

这意味着页面调用消息块并从该核心数组检索消息。然后，在布局中，您应该能够看到实际调用输出的行：

<?php echo $this->getChildHtml('global_messages') ?>

这实际上回显了会话中任何消息的正常消息块。如果您找不到这些块，请将它们添加进去。如果您需要在不同的上下文中获取消息（这可能会干扰其他站点操作），请在 phtml 文件中尝试以下操作：

<?php print $this->getLayout()->createBlock('core/messages')->toHtml(); ?>

希望有帮助！
