This is How to Add Editable Settings to Your Custom WordPress Theme
As a WordPress developer, one of the key ways to differentiate your custom theme from the competition is by providing users with the ability to easily customize the look and feel of their site. This not only enhances the user experience, but also increases the overall value of your theme.
One powerful tool that makes this possible is the WordPress Customizer API. In this article, we'll dive into how you can leverage the Customizer to add editable settings to your custom WordPress theme, allowing your users to personalize their website to their heart's content.
Understanding the WordPress Customizer API
The WordPress Customizer API is a robust framework that allows developers to integrate customizable options directly into the WordPress Customizer. This gives users an intuitive, real-time interface to preview and adjust various aspects of their website, such as colors, typography, layouts, and more.
At its core, the Customizer API is built around the concept of "Panels," "Sections," and "Controls." Panels group related customization options together, Sections organize those options within each panel, and Controls represent the individual settings that users can interact with.
Here's a quick breakdown of how these components work together:
Panels: These are the top-level containers that house multiple sections. For example, you might have a "Header" panel that contains sections for logo, navigation menu, and search bar settings.
Sections: Sections are the sub-containers within each panel, grouping related customization options. Continuing the header example, you might have a "Logo" section and a "Navigation" section within the "Header" panel.
Controls: These are the individual settings that users can interact with, such as color pickers, text inputs, or dropdown menus. Controls are added to sections to provide customization options.
By leveraging these Customizer components, you can create a seamless, intuitive experience for your users to personalize their WordPress website.
Adding Editable Settings to Your Custom Theme
Now that we have a basic understanding of the Customizer API, let's dive into the process of adding editable settings to your custom WordPress theme.
Step 1: Register the Customizer Panels, Sections, and Controls
The first step is to register your Customizer components within your theme's functions.php
file. Here's an example of how you might set up a simple "Header" panel with a "Logo" section and a "Logo Width" control:
/**
* Registers the Customizer sections, panels, and controls.
*
* @param WP_Customize_Manager $wp_customize The Customize Manager object.
*/
function flowpoint_customize_register( $wp_customize ) {
// Add the "Header" panel
$wp_customize->add_panel( 'flowpoint_header_panel', array(
'title' => __( 'Header', 'flowpoint' ),
'description' => __( 'Customize the header of your website.', 'flowpoint' ),
) );
// Add the "Logo" section within the "Header" panel
$wp_customize->add_section( 'flowpoint_header_logo', array(
'title' => __( 'Logo', 'flowpoint' ),
'description' => __( 'Customize the logo on your website.', 'flowpoint' ),
'panel' => 'flowpoint_header_panel',
) );
// Add the "Logo Width" control within the "Logo" section
$wp_customize->add_setting( 'flowpoint_logo_width', array(
'default' => 200,
'transport' => 'postMessage',
'sanitize_callback' => 'absint',
) );
$wp_customize->add_control( 'flowpoint_logo_width', array(
'label' => __( 'Logo Width', 'flowpoint' ),
'description' => __( 'Set the width of your logo in pixels.', 'flowpoint' ),
'section' => 'flowpoint_header_logo',
'type' => 'number',
'input_attrs' => array(
'min' => 50,
'max' => 500,
'step' => 10,
),
) );
}
add_action( 'customize_register', 'flowpoint_customize_register' );
In this example, we're creating a "Header" panel with a "Logo" section that contains a "Logo Width" control. Users will be able to adjust the logo width directly from the Customizer.
The add_panel()
, add_section()
, and add_control()
methods are used to register each of these Customizer components. Notice how we're also defining some basic properties, such as the title, description, and default value for the "Logo Width" control.
Step 2: Enqueue the Customizer Preview Script
To allow users to see the changes they make to the "Logo Width" control in real-time, we need to enqueue a custom JavaScript file that will handle the preview functionality.
Add the following code to your functions.php
file:
/**
* Enqueues the Customizer preview script.
*/
function flowpoint_customize_preview_js() {
wp_enqueue_script(
'flowpoint-customizer-preview',
get_template_directory_uri() . '/js/customizer-preview.js',
array( 'customize-preview' ),
'1.0.0',
true
);
}
add_action( 'customize_preview_init', 'flowpoint_customize_preview_js' );
This code will load a custom customizer-preview.js
file, which we'll create in the next step.
Step 3: Implement the Customizer Preview Script
The Customizer preview script is responsible for updating the live preview of your website when the user makes changes to the "Logo Width" control. Create a new file called customizer-preview.js
in your theme's js
directory and add the following code:
/**
* Handles the live preview of changes made in the Customizer.
*/
(function ($) {
wp.customize('flowpoint_logo_width', function (value) {
value.bind(function (newVal) {
$('.site-logo img').css('width', newVal + 'px');
});
});
})(jQuery);
This script listens for changes to the flowpoint_logo_width
setting (which we defined in the previous step) and updates the width of the .site-logo img
element accordingly. This allows users to see the changes they make to the logo width in real-time as they adjust the control in the Customizer.

Step 4: Retrieve and Use the Customizer Settings
The final step is to retrieve the user-defined settings from the Customizer and use them in your theme's templates. You can do this by using the get_theme_mod()
function, like so:
// Retrieve the logo width setting from the Customizer
$logo_width = get_theme_mod( 'flowpoint_logo_width', 200 );
// Use the logo width setting in your theme's template
<img src="<?php echo esc_url( get_theme_mod( 'custom_logo' ) ); ?>" alt="<?php echo esc_attr( get_bloginfo( 'name' ) ); ?>" style="width: <?php echo absint( $logo_width ); ?>px;">
In this example, we're first retrieving the flowpoint_logo_width
setting from the Customizer using get_theme_mod()
. We then use this value to set the width of the logo image in our theme's template.
The get_theme_mod()
function allows you to retrieve any setting that you've added to the Customizer, making it easy to integrate the user-defined values into your theme's design and functionality.
Enhancing the Customizer Experience
While the steps outlined above provide a solid foundation for adding editable settings to your custom WordPress theme, there are a few additional techniques you can use to further enhance the Customizer experience for your users:
-
Provide Live Preview: As we demonstrated in the previous steps, using the Customizer preview script to update the live preview of your website is a crucial aspect of providing a seamless customization experience.
-
Leverage Customizer Controls: The Customizer API provides a wide range of control types, such as color pickers, image uploads, and text inputs. Choosing the appropriate control type for each setting can greatly improve the user experience.
-
Implement Selective Refresh: Selective refresh allows you to update specific parts of the page instead of refreshing the entire page when a Customizer setting is changed. This can make the customization process feel more responsive and efficient.
-
Add Customizer-Specific Styles: You can add custom CSS or JavaScript to your theme to enhance the appearance and behavior of the Customizer interface, making it more visually appealing and intuitive for your users.
-
Provide Detailed Documentation: Finally, be sure to document your theme's Customizer features thoroughly, making it easy for users to understand and utilize all the customization options you've provided.
By following these best practices, you can create a truly remarkable customization experience for your WordPress theme users, setting your product apart from the competition and providing greater value to your customers.
In conclusion, the WordPress Customizer API is a powerful tool that allows you to give your users the ability to personalize their website's appearance and functionality. By leveraging Panels, Sections, and Controls, you can easily add editable settings to your custom WordPress theme, enabling users to tailor the look and feel of their site to their specific needs.
