Theme Customizer

How to Enable Social Icons in the WordPress Theme Customizer

I figure I might as well write about this before I deprecate it in my upcoming Theme. Social Nav Menus are much better. A week or two ago as I was getting deep into developing a new WordPress Theme, I stumbled upon some pretty good looking code that would allow me to add Social Media Icons to the Theme Customizer like so: theme_customizer_social_icons At the time, it was a superb idea. I was just learning about all the possibilities the Theme Customizer affords developers and it was fun to implement the code and watch it work so smoothly. However, after watching Morten Rand-Hendriksen's Building Themes from Scratch Using Underscores and reading Justin Tadlock's post on building Social Nav menus, I think I will scratch this bit of code in favor of Tadlock's solution. It just makes sense to not want to have to re-enter your Social Media links in every new Theme you install. Why not just leave all the Social links you want in a nav menu and use your Theme to style and output it specifically as a Social menu? TwentyFifteen also does just that. (See #3 in this post.) Nevertheless, I felt that the code itself was worth my time to invest in learning, so I'm reproducing it here for reference. This code is modified slightly from the example I found - I've included email as an option. It should be pretty easy to see how it's done: add_section(), add_setting(), add_control()
 /**
 * Social site icons for Quick Menu bar
 * 
 * @link: https://www.competethemes.com/social-icons-wordpress-menu-theme-customizer/
 */
 $wp_customize->add_section( 'social_settings', array(
     'title' => __( 'Social Media Icons', 'theme_slug' ),
     'priority' => 100,
 ));
 
 $social_sites = theme_slug_get_social_sites();
 $priority = 5;
 
 foreach( $social_sites as $social_site ) {
 
     $wp_customize->add_setting( "$social_site", array(
         'type' => 'theme_mod',
         'capability' => 'edit_theme_options',
         'sanitize_callback' => 'esc_url_raw',
     ));
 
     $wp_customize->add_control( $social_site, array(
         'label' => ucwords( __( "$social_site URL:", 'social_icon' ) ),
         'section' => 'social_settings',
         'type' => 'text',
         'priority' => $priority,
     ));
 
     $priority += 5;
 }
function theme_slug_get_social_sites()
/**

 * @return array
 * 
 * @link: https://www.competethemes.com/social-icons-wordpress-menu-theme-customizer/
 */
function theme_slug_get_social_sites() {
 
     // Store social site names in array
     $social_sites = array(

             $active_sites[] = $social_site;
         }
     }
 
     // For each active social site, add it as a list item
     if ( !empty( $active_sites ) ) {
         echo "<ul class='social-media-icons'>";
 
         foreach ( $active_sites as $active_site ) { ?>

             <li>
             <a href="<?php echo get_theme_mod( $active_site ); ?>">
             <?php if( $active_site == 'vimeo' ) { ?>
                 <i class="fa fa-<?php echo $active_site; ?>-square"></i> <?php
             } else if( $active_site == 'email' ) { ?>
                 <i class="fa fa-envelope"></i> <?php
             } else { ?>
                 <i class="fa fa-<?php echo $active_site; ?>"></i> <?php
             } ?>
             </a>
             </li> <?php
         }
         echo "</ul>";
     }
}
Oh, and obviously you'll need to remember to enqueue FontAwesome in your WordPress Theme in order to make this all function properly. Then, the CSS styling is totally up to you.

Default WordPress Theme Customizer Controls

I've recently been messing around with the WP Theme Customizer a bunch and have been looking for the names of all the default settings, sections, and controls. I found them in a file in the wp-includes folder:
/wp-includes/class-wp-customize-manager.php
The various default section names, setting names, and 'priority' are listed below.This is mostly useful if you're trying to simply rearrange the position ('priority' => 20) of some options, or want to rename some of them like so:
$wp_customize->get_section( 'nav' )->title = __( 'Menus', 'theme_slug' );
$wp_customize->get_control( 'blogname' )->priority = 10;
$wp_customize->get_setting( 'background_color' )->default = '#169A70';
  1. Site Title & Tagline ('title_tagline'), 20
    1. 'blogname'
    2. 'blogdescription'
    3. 'display_header_text'
  2. Colors ('colors'), 40
    1. 'header_textcolor'
    2. 'background_color'
  3. Header Image ('header_image'), 60
    1. 'header_image'
    2. 'header_image_data'
  4. Background ImageĀ ('background_image'), 80
    1. 'background_image_thumb'
    2. 'background_repeat'
    3. 'background_position_x'
    4. 'background_attachment'
  5. Navigation ('nav'), 100
    1. "nav_menu_locations[{$location}]"
  6. Widgets ('widgets'), 110
  7. Static Front Page ('static_front_page'), 120
    1. 'show_on_front'
    2. 'page_on_front'
    3. 'page_for_posts'
The code specifically for 'widgets' is located in:
/wp-includes/class-wp-customize-widgets.php
The full code for the default Theme Customizer settings is here:
 /**
