Missing argument 2 for the function in wordpress

Question

I am creating a function in wordpress function.php, but I am getting an error:

Missing argument 2 for get_appcara_child() in C:\wamp\www\appcara\wp-content\themes\appkara\functions.php on line 617

The function is giving the correct output, but I don't know why it is displaying this warning

My function.php is

add_action( 'init', 'get_appcara_child',2 );
function get_appcara_child($post,$parent)
{
    echo $post;

    echo $parent;
}

Calling at page.php

$child= get_appcara_child($post->ID , $post->post_parent);

By using add_action() does Wordpress not call the function at some point (probably at initialization)? If so, are you sure Wordpress gives it two arguments? If not then you should look into that. Have you read the documentation thoroughly? — Sverri M. Olsen

10

The format is:

add_action( HOOK, CALLBACK, PRIORITY, NUMBER OF PARAMETERS );

You set the priority to 2 and it should be the parameters ($post,$parent). Correction:

add_action( 'init', 'get_appcara_child', 10, 2 );

PS: 10 is the default priority.

<script data-cfasync="false" type="text/javascript">
    (function(w, d) { 
        var s = d.createElement('script'); 
        s.src = '//cdn.adpushup.com/39884/adpushup.js'; 
        s.type = 'text/javascript'; s.async = true; 
        (d.getElementsByTagName('head')[0] || d.getElementsByTagName('body')[0]).appendChild(s); 
    })(window, document);</script>
