So, you’re diving into the world of WordPress hooks, huh? It’s a pretty cool journey, and today we’re talking about the admin_print_scripts action. This hook is your go-to when you need scripts to be printed for all admin pages. To use it, you’ll first register it using add_action. You can drop this code into your theme’s functions.php or even better, in a custom WordPress plugin. At WePlugins, we always suggest creating a custom plugin to keep your theme updates smooth and worry-free.
Want to add some inline JavaScript to your admin pages? Here’s how you can achieve that using the admin_print_scripts hook.
function weplugins_admin_inline_js(){
echo "<script type='text/javascript'>n";
echo 'var pluginUrl = ' . wp_json_encode( WP_PLUGIN_URL . '/my_plugin/' ) . ';';
echo "n</script>";
}
add_action( 'admin_print_scripts', 'weplugins_admin_inline_js' );
Let’s see how you can execute a custom function when this action occurs in your WordPress site.
function weplugins_execute_on_admin_print_scripts_event(){
// Your custom code here
}
// Add the action
add_action( "admin_print_scripts", "weplugins_execute_on_admin_print_scripts_event");
Need to remove a previously registered hook? No worries, here’s how you do it.
remove_action( "admin_print_scripts", "weplugins_execute_on_admin_print_scripts_event");
Remember to provide the same callback function name, priority, and the number of arguments when removing the hook callback.
