This function is part of the WordPress core, and as such, it’s available in all versions of WordPress since its implementation.

Examples

Call the function

This simple usage of the function triggers the printing of the JavaScript templates.

// Trigger the printing of JS templates for the theme-browsing UI
customize_themes_print_templates();

Use inside a function

In this example, we create a function that calls customize_themes_print_templates() when a certain condition is met.

function my_custom_function() {
    if (is_customize_preview()) {
        // Print JS templates for theme-browsing UI if in customizer preview
        customize_themes_print_templates();
    }
}

This example hooks the function into the ‘customize_controls_print_footer_scripts’ action, to print the templates in the footer.

add_action('customize_controls_print_footer_scripts', 'customize_themes_print_templates');

Removing the function from an action hook

This example removes the function from the ‘customize_controls_print_footer_scripts’ action.

remove_action('customize_controls_print_footer_scripts', 'customize_themes_print_templates');

Check if function exists

This example checks if the function exists before calling it. 

if (function_exists('customize_themes_print_templates')) {
    // Function exists, so print the JS templates for theme-browsing UI
    customize_themes_print_templates();
}
