无法将js和CSS文件添加到后台 [英] Can't add js and css files to back office

问题描述

我想在模块中添加JS和CSS文件到后台.但是我收到错误消息:尝试调用类"AdminModulesController"的名为"registerStylesheet"的未定义方法.

I want to add JS and CSS files to back office in my module. But I get error: Attempted to call an undefined method named "registerStylesheet" of class "AdminModulesController".

我看过其他帖子(例如在prestashop的页脚处显示我的模块JS )，或在此处https://devdocs.prestashop.com/1.7/themes/getting-started/asset-management/

I've seen other posts (like this Show my module JS at footer in prestashop) or here https://devdocs.prestashop.com/1.7/themes/getting-started/asset-management/

因此，我想避免使用addJS()函数，因为此函数已过时.但是，当我尝试使用$ this-> context-> controller-> registerStylesheet()和$ this-> context-> controller-> registerJavascript()时，出现上述错误.

So I want to avoid addJS() function as this is depreciated. But when I try to use $this->context->controller->registerStylesheet() and $this->context->controller->registerJavascript() I get the above error.

这是我的整个钩子代码:

This is my whole hook code:

public function hookActionAdminControllerSetMedia($params)
{ 
    $this->context->controller->registerStylesheet(
        'mb_pages_content',
        'modules/'.$this->name.'/styles/admin.min.css'
    ); 

    $this->context->controller->registerJavascript(
        'mb_pages_content',
        'modules/'.$this->name.'/js/admin.js'
    );
}

我检查过我的东西是什么:$ this-> context-> controller但实际上并没有registerStylesheet()和registerJavascript()方法.我想念什么?我所做的一切都完全按照互联网上任何地方的描述进行操作，为什么我会收到错误消息?

I've checked what kind of thing is my: $this->context->controller but it doesn't indeed have registerStylesheet() and registerJavascript() methods. What am I missing? i do everything exactly as described everywhere in the internet, why do I get the error?

推荐答案

使用哪种方法的说明:

这些是PrestaShop 1.7中的 FrontController 方法: registerJavascript 和 registerStylesheet .

These are FrontController methods in PrestaShop 1.7: registerJavascript and registerStylesheet.

这些是PrestaShop 1.7中的旧版(不推荐使用)FrontController 方法: addJS 和 addCSS .

These are legacy (deprecated) FrontController methods in PrestaShop 1.7: addJS and addCSS.

这些是PrestaShop 1.7、1.6、1.5中的 AdminController 方法: addJS 和 addCSS .

These are AdminController methods in PrestaShop 1.7, 1.6, 1.5: addJS and addCSS.

因此，通过模块类为后台添加JS和CSS文件(例如AdminController)的正确示例是:

public function hookActionAdminControllerSetMedia($params)
{ 
    // Adds your's CSS file from a module's directory
    $this->context->controller->addCSS($this->_path . 'views/css/example.css'); 

    // Adds your's JavaScript file from a module's directory
    $this->context->controller->addJS($this->_path . 'views/js/example.js');
}
