Question

我在我的网站上使用CakePHP，我需要解析变量并将其写入布局中。该变量位于MySQL，表“articles”，列“author”。

如果在我写的文章中，它会向我显示作者，但如果我在views / layout / default.thtml中写它，它不会向我显示任何内容。

有一种简单的方法吗？

您是否在正确的控制器功能中获得此变量？也许你需要将它插入到beforeRender函数中（http://planetcakephp.org/aggregator/items/1398-utilizing-the-appcontrollerbeforerender-to-assign-cakephps-controller-attribut）

执行此操作的一个选项是使用CakePHP的requestAction并将其放在可以标记为默认布局的元素中。基本上你会做类似于以下的事情

//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)); ?>
