Replacing parent action of Custormizr theme

Question

I created my own child theme. Everything works great except I can't seem to unregister a hoook.

$this is class TC_footer_main and the following code is in the __construct

add_action ( '__colophon'       , array( $this , 'tc_colophon_center_block' ), 20 );

I tried several remove actions with no success. I am just trying to change/remove the footer:

remove_action( '__colophon' , 'tc_colophon_center_block' , 55);

or

remove_action( '__colophon' , array('TC_footer_main','tc_colophon_center_block') , 55);

I've also tried

remove_action( '__colophon' , TC_footer_main::$instance->tc_colophon_center_block() , 55);

But that threw an error as TC_footer_main was not loaded by the time my functions.php file ran.

Answer 1

I am just trying to change/remove the footer:

I think you're making it way more complex, to modify the output of the tc_colophon_center_block() method, than it has to be.

Just use the tc_credits_display filter:

add_filter( 'tc_credits_display', function( $html )
{
    // Modify output to your needs!
    return $html;
} );

to modify that block to your needs.

To totally remove the output (if that's allowed), simply use:

add_filter( 'tc_credits_display', '__return_null', PHP_INT_MAX );

You have further access to filters like:

• tc_copyright_link
• tc_credit_link
• tc_wp_powered

to choose from.

That's it!

For your purpose add the following code in function.php. It will get call on after_setup_theme hook.

// replace parent function
function child_theme_function () {
    // your code goes here
 }

function my_theme_setup () {
    remove_action( '__colophon', 'tc_colophon_center_block', 1000 );
    add_action( '__colophon', 'child_theme_function', 1000 );
}
add_action( 'after_setup_theme', 'my_theme_setup' );

You can also try for overriding the parent class from child class as described here: https://thethemefoundry.com/tutorials/advanced-customization-replacing-theme-functions/
