变量布局

Question

我在我的网站上使用CakePHP，我需要解析一个变量并将其写入布局。该变量在MySQL中，表“articles”，列“author”。

如果在一篇文章中我写它显示作者， ，但如果我写在views/layout/default.thtml它不会显示任何东西。

有没有简单的方法来做到这一点？

您是否在右侧控制器功能中获取了此变量？也许你需要将它插入到一个beforeRender函数中（http://planetcakephp.org/aggregator/items/1398-utilizing-the-appcontrollerbeforerender-to-assign-cakephps-controller-attribut）

一个选项可以做到这一点是通过使用CakePHP的requestAction并将其放置在可以标记为默认布局的元素中。基本上你会做类似以下的事情

//Create a function in your articles controller as such 
function authorName($articleId = NULL){  
    //Return Author if an ID is passed 
    if(!empty($articleId)){ 
     $this->Article->recursive = -1; 
     $article = $this->Article->findById($articleID); 

     $return $article['Article']['author']; 
    } 

} 

// Then create an element author_name.ctp and place it in views/elements 
// that requests the AuthorID form the above function 
<div> 
<?php 
    $author = $this->requestAction(
     array(
      'controller' => 'articles', 
      'action' => 'authorName' 
     ), 
     array(
      'pass' => $article_id 
     ) 
    ); 
    echo $author; 
?> 
</div> 

// Then in you default layout or anywhere else 
// you can include the element as such 
// You have to figure out a way to get the $id. If you can place a screenshot 
// Or some code of you default layout area where you need this, we can help you further 
<?php echo $this->element('author_name', array('article_id' => $id)); ?>
