在写本文前我不得不说一句,其实我是不想用smarty的,我想尝试一下twig,但是phpstorm的Twig插件真要命,卡成翔,所以我只能用smarty。为什么不用prado了呢?官方说不支持了,我晶啊 在使用smarty的时候官方的代码和例子看上去很美,不过要注意几点 1、用yii

在写本文前我不得不说一句,其实我是不想用smarty的,我想尝试一下twig,但是phpstorm的Twig插件真要命,卡成翔,所以我只能用smarty。为什么不用prado了呢?官方说不支持了,我晶啊

在使用smarty的时候官方的代码和例子看上去很美,不过要注意几点

1、用yii2-smarty,还是必须得用layout,如果你不支持layout文件,默认就是/layouts/main.php,天啊,为什么是PHP?而且在这里面也还真的能用PHP代码。整个都崩溃了

2、你可以指定layout文件,比如:main.tpl,OK你必须得象PHP文件一样,得写{$this->head()},{$this->startBody()}{$this->endPage()}等,否则 ClientScript功能就无法使用

3、如果你指定layout=false,那么,就不支持ClientScript了。因为你incude file='xxx.tpl',在每一个独立的文件里都必须要象2中一个个的this->head(),this->endPage全写上

4、再来一个bug:{registerJsFile url=''},这个函数有BUG

原来是:

    public function functionRegisterJsFile($params, $template)  
    {  
        if (!isset($params['url'])) {  
            trigger_error("registerJsFile: missing 'url' parameter");  
        }  
        $url = ArrayHelper::remove($params, 'url');  
        $key = ArrayHelper::remove($params, 'key', null);  
        $depends = ArrayHelper::remove($params, 'depends', null);  
        if (isset($params['position']))  
            $params['position'] = $this->getViewConstVal($params['position'], View::POS_END);  
        Yii::$app->getView()->registerJsFile($url, $depends, $params, $key);  
    }  

改成为:

    /** 
     * Smarty function plugin 
     * Usage is the following: 
     * 
     * {registerJsFile url='http://maps.google.com/maps/api/js?sensor=false' position='POS_END'} 
     * 
     * Supported attributes: url, key, depends, position and valid HTML attributes for the script tag. 
     * Refer to Yii documentation for details. 
     * The position attribute is passed as text without the class prefix. 
     * Default is 'POS_END'. 
     * 
     * @param $params 
     * @param \Smarty_Internal_Template $template 
     * @return string 
     * @note Even though this method is public it should not be called directly. 
     */  
    public function functionRegisterJsFile($params, $template)  
    {  
        if (!isset($params['url'])) {  
            trigger_error("registerJsFile: missing 'url' parameter");  
        }  
        $url = ArrayHelper::remove($params, 'url');  
        $key = ArrayHelper::remove($params, 'key', null);  
        $params['depends'] = ArrayHelper::remove($params, 'depends', null);  
        if (isset($params['position']))  
            $params['position'] = $this->getViewConstVal($params['position'], View::POS_END);  
        Yii::$app->getView()->registerJsFile($url, $params, $key);  
    }  

其实就是$params['depends']这个参数。registerJsFile只能接受3个参数,但事实上用了4个参数,所以调整一下即可
