Filter & Action Hooks

Filters

Filters provide a flexible way to modify project elements in the child-theme’s functions.php file without requiring a copy of a template file. This ensures an update-proof approach to customization while allowing for creative adjustments.

How it works

Many classes and other elements are wrapped in filters, enabling modifications without storing template copies in a child theme. A basic filter consists of:

• A filter name, e.g., bootscore/example/filter/name
• A returnable value, such as a string containing one or more CSS classes

<div class="<?= esc_attr(apply_filters('bootscore/example/filter/name', 'one or more classes')); ?>">
...
</div>

Result in frontend:

<div class="one or more classes">
...
</div>

To modify these classes via a child theme, a custom function is required. This function must:

• Have a unique function name my_fancy_filter_function
• Return the modified value (in this case, CSS classes)
• Be hooked into the appropriate filter bootscore/example/filter/name

/**
 * Change one or more classes into my-custom-class
 */
function my_fancy_filter_function() {
  return "my-custom-class";
}
add_filter('bootscore/example/filter/name', 'my_fancy_filter_function', 10, 2);

Result in frontend

<div class="my-custom-class">
...
</div>

Location

When a filter is used in multiple files, an additional location argument can specify where it is applied:

<?= esc_attr(apply_filters('bootscore/example/filter/name', 'one or more classes', 'location-in-which-template-this-filter-is-used')); ?>

For example, the bootscore/class/container filter is present in several template files:

In header.php:

<?= esc_attr(apply_filters('bootscore/class/container', 'container', 'header')); ?>

In archive.php:

<?= esc_attr(apply_filters('bootscore/class/container', 'container', 'archive')); ?>

Applying a basic filter without specifying a location modifies all instances:

/**
 * Change entire container classes
 */
function change_entire_containers() {
  return "container-fluid";
}
add_filter('bootscore/class/container', 'change_entire_containers', 10, 2);

To modify only a specific instance, the location parameter can be checked:

/**
 * Change container class in a single file
 */
function change_container_in_single_file($string, $location) {
  if ($location == 'header') {
    return "container-fluid";
  }
  return $string;
}
add_filter('bootscore/class/container', 'change_container_in_single_file', 10, 2);

For multiple locations, conditions can be expanded:

/**
 * Change container classes in selected files
 */
function change_container_in_selected_files($string, $location) {
  if ($location == 'header' || $location == 'footer-top' || $location == 'footer-columns' || $location == 'footer-info') {
    return "container-fluid";
  }
  return $string;
}
add_filter('bootscore/class/container', 'change_container_in_selected_files', 10, 2);

Actions

While filters modify existing content, actions are used to add new elements. Actions can be used for various tasks, such as inserting a message, opening a <div> in one action and closing it in another, or adding more complex functionality.

How it works

A basic action looks like this:

<?php do_action( 'bootscore_before_masthead' ); ?>

To add content at this action hook, the following are required:

• An unique function name (e.g., my_fancy_action_function)
• The action name (e.g., bootscore_before_masthead)
• An echo statement to output content

/**
 * Add an alert message before the masthead.
 */
function add_alert_before_masthead() {
  echo '<div class="alert alert-danger" role="alert">This is an important message!</div>';
}
add_action('bootscore_before_masthead', 'add_alert_before_masthead');

Location

When an action is used in multiple files, an additional location argument can specify where it is applied:

<?php do_action( 'bootscore_after_primary_open', 'page-sidebar-left' ); ?>

Applying a basic action without specifying a location adds content to all instances:

/**
 * Add an alert message after primary open.
 */
function add_alert_after_primary_open() {
  echo '<div class="alert alert-danger" role="alert">This is an important message!</div>';
}
add_action('bootscore_after_primary_open', 'add_alert_after_primary_open');

To modify only a specific instance, the location parameter can be checked:

/**
 * Add an alert message after primary open for 'page-sidebar-left' location.
 */
function add_alert_after_primary_open($location) {
  if ($location == 'page-sidebar-left') {
    echo '<div class="alert alert-warning" role="alert">This is a warning alert for page-sidebar-left!</div>';
  }
}
add_action('bootscore_after_primary_open', 'add_alert_after_primary_open');

For multiple locations, the conditions can be expanded:

/**
 * Add an alert message after primary open for 'page-sidebar-left' and 'archive' location.
 */
function add_alert_after_primary_open($location) {
  if ($location == 'page-sidebar-left' || $location == 'archive') {
    echo '<div class="alert alert-warning" role="alert">This is a warning alert for page-sidebar-left and archive!</div>';
  }
}
add_action('bootscore_after_primary_open', 'add_alert_after_primary_open');

Visual guide

The following snippet will hook an alert alert-warning to all actions to create a visual map, as shown in the screenshot in header.php. If an action has a location, it will also be displayed.

 */
function header_button_class() {
  return "btn btn-light";
}
add_filter('bootscore/class/header/button', 'header_button_class', 10, 2);

Change a single button class only. For example the navbar-toggler:

    return "btn btn-light";
  }
  return $string;
}
add_filter('bootscore/class/header/button', 'header_button_class', 10, 2);

Or select multiple buttons. For example account-toggler and mini-cart-toggler:

/**
 * Change selected header buttons
 */
function header_button_class($string, $location) {

    <a class="position-absolute top-50 start-50 translate-middle d-sm-none" href="<?= esc_url(home_url()); ?>">
      <img src="<?= esc_url(get_stylesheet_directory_uri()); ?>/assets/img/logo/logo-sm.svg" alt="<?php bloginfo('name'); ?> Logo" class="d-td-none">

Breadcrumb

Change general layout

/**

 */
function change_breadcrumb_a_class() {  return 'text-decoration-none link-danger';
}
add_filter('bootscore/class/breadcrumb/item/link', 'change_breadcrumb_a_class');

Add breadcrumb to pages, search results and archives

Bootscore follows the WordPress standard and only displays breadcrumbs on single posts (where they’re most commonly needed). However, breadcrumbs can easily added to pages, archives, search results, and custom templates using the available action hooks.

/**
 * Hook breadcrumb to 'page-full-width-image.php'
 */
function hook_breadcrumb_to_page_full_width_image( $location ) {
  if ( $location === 'page-full-width-image' ) {
    the_breadcrumb();
  }
}
add_action( 'bootscore_after_featured_image', 'hook_breadcrumb_to_page_full_width_image'); 


/**
 * Hook breadcrumb to all page, archive and search templates
 */
function hook_breadcrumb_to_pages_archive_search( $location ) {
  if ( $location === 'archive' || $location == 'search' || $location == 'page' || $location == 'page-sidebar-left' || $location == 'page-sidebar-none') {
    the_breadcrumb();
  }
}
add_action( 'bootscore_after_primary_open', 'hook_breadcrumb_to_pages_archive_search'); 

Hook into breadcrumb to handle CPT’s

The breadcrumb system can be extended to support any custom post type by using the bootscore/breadcrumb/handler filter hook:

/**
 * Add CPT handler
 * Example https://github.com/bootscore/bootscore/blob/main/woocommerce/inc/wc-breadcrumb.php
 */
function my_cpt_breadcrumb_handler($handled) {
  // Only handle our custom post type
  if (is_singular('my_cpt')) {
    // Your custom breadcrumb logic
    return true; // Mark as handled
  }
  return $handled;
}
add_filter('bootscore/breadcrumb/handler', 'my_cpt_breadcrumb_handler', 15, 1);

Shortcode

For maximum flexibility, Bootscore includes a [bs-breadcrumb] shortcode that displays breadcrumb navigation anywhere in your content. This is particularly useful for widget areas, custom page templates (like Page Blank), or any location where breadcrumbs can’t be added via standard action hooks. The shortcode automatically respects all the same conditional logic and formatting as the main breadcrumb function.

[bs-breadcrumb]

Archive/Loop

Hide ‘Category:’ in archives but keep ‘Tag:/Month:/Author:’

/**
 * Hide 'Category:' in archives but keep  'Tag:/Month:/Author:'
 *
 * add_filter( 'get_the_archive_title_prefix', '__return_empty_string' ); // Removes all
 */
add_filter( 'get_the_archive_title_prefix', function( $prefix ) {

  if (is_author() && $location === 'archive') {
    $author_id = get_queried_object_id(); // Get the author ID
    echo '<div class="flex-shrink-0 me-3">';
