WP_Customize_Nav_Menu_Item_Control::render_content() in WordPress

Guide for using WP_Customize_Nav_Menu_Item_Control::render_content()

Hello everyone! Today we will talk about one of the classes in WordPress called WP_Customize_Nav_Menu_Item_Control and its method render_content(). This class allows us to customize navigation menu items on the WordPress Customizer page. In this article, I will explain in detail how to benefit from this class.

This class and its method render_content() are used to generate HTML content for navigating menu items and related controls. This method typically renders the controls available on the WordPress Customizer's navigation menu page, allowing developers to easily add their HTML and JavaScript elements.

Now, let's take a look at how to utilize this method. You can use this method to add custom capabilities in your own menus. For example, you might want to add custom fields for link editing or changing menu icons. These instructions can make your controls more unique and attractive!

Before we can review this code, remember that you must inherit from WP_Customize_Control to create custom controls. Let's take a look at the code below:

class My_Custom_Menu_Control extends WP_Customize_Nav_Menu_Item_Control {
    public function render_content() {
        // HTML code for displaying the content of the control
        echo 'Link Title:'; 
        echo '';
    }
}

From the code above, we see that we create a new custom class named My_Custom_Menu_Control that extends WP_Customize_Nav_Menu_Item_Control. Now let’s explain each line of this code:

• class My_Custom_Menu_Control extends WP_Customize_Nav_Menu_Item_Control {:



We are creating a new class named My_Custom_Menu_Control that inherits from WP_Customize_Nav_Menu_Item_Control.



• public function render_content() {:



This method is used to generate the content of the control. Here is where we add HTML for display on the Customizer page.



• echo 'Link Title:';:



This line generates a label for the input field that indicates what the user should enter.



• echo '';:



This line creates an input field that shows the current value of the link. The esc_attr() function is used to sanitize data in WordPress.
