当内部调用方法时触发钩子的方法

Question

I'm using CodeIgniter hook, which I've defined like below:

$hook['post_controller'][] = 
    array(
        'class'    => 'notify',
        'function' => 'sendEmail',
        'filename' => 'notify.php',
        'filepath' => 'controllers'
    );

And it's getting called whenever user browse a url. After each method got executed it's trigger the above hook. This is working fine the way I want.

Let's say I'm browsing something like: https://localhost/dashboard/index which will run dashboard controller index method and then trigger my hook.

Now the problem is I'm calling another method list of dashboard class from index method. So when index method called list method and it's got executed I want to trigger the hook as well, which is not happening right now.

Anyone help me on this!

Answer 1

you can use flag to decide your hook run or not. for example: in your list method on dashboard controller:

$this->process_email = FALSE;

then in your hook notify. you need to check the flag before do any process.

function sendEmail(){
    $CI =& get_instance();
    if (property_exists($CI, "process_email") && $CI->process_email === FALSE)
    {
        return;
    }

   //`do your stuff here to send email..


}`
