Introduction to Function is_same_theme in WP_REST_Themes_Controller
The function is_same_theme in the WP_REST_Themes_Controller class is one of the important functions in WordPress that is used for checking the type of theme being used. This function helps to determine whether a given theme name corresponds to the currently active theme. This capability helps us to prevent irrelevant background requests from leaking out and ensures that we only display the data of a specific active theme.
WordPress, as a popular Content Management System (CMS), allows developers this capability to easily create and manage various themes for their websites. In some cases, it may be necessary to ensure that our REST API requests are only limited to specific themes. Here, the function is_same_theme comes into play.
This function compares the given theme name with the theme name that has been provided. If the names match, the result will be true, and otherwise it will return false. This behavior allows for better management at the code level for us and provides us with this flexibility that only under specific conditions can we execute certain operations such as returning specific data.
In continuation, we will review a sample code snippet on how to utilize this function, which can help you understand how to make better use of this functionality for your users.
$controller = new WP_REST_Themes_Controller();
$current_theme = wp_get_theme();
$is_same = $controller->is_same_theme( $current_theme->get_stylesheet() );
if ( $is_same ) {
echo 'This theme is active!';
} else {
echo 'This theme is not active.';
}Code Explanation
In this code example, we create an instance of the WP_REST_Themes_Controller class:
$controller = new WP_REST_Themes_Controller();Next, we retrieve the currently active theme using the wp_get_theme() method:
$current_theme = wp_get_theme();In the next step, using the is_same_theme function, we check whether the active theme is the same as the provided theme:
$is_same = $controller->is_same_theme( $current_theme->get_stylesheet() );Ultimately, based on the result of the check, we display an appropriate message:
if ( $is_same ) { echo 'This theme is active!'; } else { echo 'This theme is not active.'; }
