在Codeigniter中手动调用/调用钩子 [英] Calling/invoking a hook manually in Codeigniter

问题描述

我在网络上搜索了手动呼叫/调用钩子和类似内容，但找不到任何东西。 Codeigniter中有这样的事情吗？我有一个钩子，下面有一个钩子，它会按预期触发，以防万一，如果没有，我想在代码中手动调用它。

I searched for calling/invoking a hook manually and similar stuff on the web but couldn't find anything. Is there a such thing in codeigniter? I have a hook below which gets triggered as expected but just in case if doesn't, then I want to invoke it manually in my code.

谢谢

$hook['post_controller_constructor'] [] =
array(
    'class'    => 'load_designs',
    'function' => 'do_load',
    'filename' => 'load_designs_hook.php',
    'filepath' => 'hooks',
    'params'   => ''
    );

推荐答案

要调用钩子，您可以加载 Hooks 核心类，并通过 _call_hook（）方法调用该hook，如下所示：

In order to call a hook, you could load the Hooks core class and call the hook by _call_hook() method as follows:

在您的控制器中：

$hook =& load_class('Hooks', 'core');
$hook->_call_hook('post_controller_constructor');

但是，如果您需要调用钩子类的特定方法，则应该手动进行：

However, if you need to call a specific method of a hook class, you should do that manually:

if (! file_exists($file_path = APPPATH . 'hooks/MyClass.php'))
{
    exit('The hook file does not exist.');
}

// load the hook file.
require $file_path;

$hook = new MyClass();
$hook->Myfunction(array('Hello', 'World!'));

如果需要，您还可以创建一个辅助函数来执行上述逻辑。

You can also make a helper function to do the above logic if needed.
