I have used
add_filter( 'pre_site_transient_update_plugins', create_function( '$a', "return null;" ) );
and
add_filter( 'pre_site_transient_update_themes', create_function( '$a', "return null;" ) );
or define('DISALLOW_FILE_MODS', true );
in my theme functions.php
or wp-config.php
to disable themes/plugins updates or hide admin side theme/plugin editor.
I want to implement these functionality into my custom plugin and when i putted these hooks in my plugin file. It didn't work.
Please help me out how can i implement these hooks in my plugins so it could disable theme/plugin updates.
