Hooks and Filters

Overview

Teydea Login Customizer provides PHP actions, PHP filters, and JavaScript filters that allow developers to extend or modify the plugin’s behavior. These hooks follow standard WordPress and @wordpress/hooks conventions.

PHP Actions

Fires before the form column is rendered on the login page. Use this to add custom HTML content before the main login form area.

add_action( 'custom_login__before_with_form_column', function () {
    echo '<div class="my-custom-banner">Welcome</div>';
} );

custom_login__inside_column

Fires inside a layout column on the login page.

custom_login__after_with_form_column

Fires after the form column is rendered. Use this to add custom HTML content after the main login form area.

PHP Filters

    $classes[] = My_Custom_Adjuster::class;
    return $classes;
} );

        // Add a custom attribute to the login form
        $forms = $xpath->query( '//form[@id="loginform"]' );
        if ( $forms && $forms->length > 0 ) {
            $forms->item( 0 )->setAttribute( 'data-custom', 'value' );
