Sometimes you need to add some more classes to a site element in Genesis. It took me ages to find a proper list and how to do it so here are a few examples and the complete list of filters. Happy coding!

Why would you want to use these? Well you could use them to add Bootstrap classes, in my latest update of SpectacularStays I used it for implementing the Aesop Story Engine into my Genesis Theme.

Adding a class to the header

//* Add custom classes to navigation menu
add_filter( 'genesis_attr_site-header', 'atp_new_header_class' );
function atp_new_header_class( $attributes ) {
 $attributes['class'] = 'site-header new-class-header clearfix fixed';
return $attributes;
}

Adding a class to the post

//* Add custom classes to posts
add_filter( 'genesis_attr_entry', 'atp_post_class' );
function atp_post_class( $attributes ) {
 $attributes['class'] = 'atp-entry-content clearfix';
return $attributes;
}

Genesis WordPress Framework adding custom classes to markup This gist was originally created as an example of what I perceived to be an inconsistent behavior, my error was failing to attach my code to action `genesis_setup`. Corrected version now appears below. 20131027 – merged Gary Jones’s fork with corrections and refactoring

<?php
/* 
 * Examples to add custom classes to Genesis WordPress Framework Markup when using HTML5 output
 */
add_action( 'genesis_setup', 'srf_add_cust_classes', 15 ); // Priority 15 ensures it runs after Genesis itself has setup.
function srf_add_cust_classes() {
    add_filter( 'genesis_attr_site-inner', 'srf_attr_site_inner' );
    add_filter( 'genesis_attr_content-sidebar-wrap', 'srf_attr_content_sidebar_wrap' );
    add_filter( 'genesis_attr_content', 'srf_attr_content' );
    add_filter( 'genesis_attr_sidebar-primary', 'srf_attr_sidebar_primary' );
} // Don't add a closing marker comment here - it just clutters the code

// Don't nest functions, move them outside of the hooked in function. While nested functions work, if the outer function is called again for whatever reason, PHP will throw a wobbly when it tries to redefine an existing function.

// Just for fun, I've refactored the common code into one function, and improved it with sanitization.

function srf_add_class( $attr, $class ) {
    $attr['class'] .= ' ' . sanitize_html_class( $class );
    return $attr;
}

// Now the rest of the functions are one line each, and the name of the called function tells us what's happening (add a class).

function srf_attr_site_inner( $attr ) {
    return srf_add_class( $attr, 'example-class-1' );
}

function srf_attr_content_sidebar_wrap( $attr ) {
    return srf_add_class( $attr, 'example-class-2' );
}

function srf_attr_content( $attr ) {
    return srf_add_class( $attr, 'example-class-3' );
}

function srf_attr_sidebar_primary( $attr ) {
    return srf_add_class( $attr, 'example-class-4' );
}

Add the following snippets to your functions.php.

Remove page title from specific page

This snippet is super useful, it removes page titles from specific pages. You could also use the Genesis title toggle to have a button on each page

add_action( 'get_header', 'remove_titles_home_page' );
function remove_titles_home_page() {
    if ( is_home() ) {
        remove_action( 'genesis_entry_header', 'genesis_do_post_title' );
    }
}

Add jQuery BXslider to your project

This is how you can quickly add the wonderful jQuery plugin BXslider. You target the jQuery function to the div container with a list.

add_action( 'genesis_setup', 'genesischild_theme_setup' );
function genesischild_theme_setup() { 
	add_action( 'genesis_after','genesischild_js_slider' );
}

//Jquery BXslider
function genesischild_js_slider() {
	echo 	"<script> jQuery(document).ready(function(){
  	jQuery('.bxslider').bxSlider({ auto:true });
					});
		</script>";
}

function bxslider_scripts_style(){
	wp_enqueue_script( 'bxslider',  get_stylesheet_directory_uri() . '/js/jquery.bxslider.min.js', array( 'jquery' ), '4.1.2', true );
	wp_enqueue_style( 'bxslider-css',  get_stylesheet_directory_uri() . '/css/jquery.bxslider.css' );
}
add_action( 'wp_enqueue_scripts', 'bxslider_scripts_style');

Useful WooCommerce Billing/Shipping snippets

Simplify your checkout by removing non-essential fields and changing the order. It does wonders with your conversion rate.

// WooCommerce Checkout Fields Hook
add_filter( 'woocommerce_checkout_fields' , 'custom_wc_checkout_fields' );
// Change order comments placeholder and label, and set billing phone number to not required.
function custom_wc_checkout_fields( $fields ) {
	$fields['billing']['billing_phone']['required'] = false;
	$fields['shipping']['shipping_phone']['required'] = false;
	$address_fields['shipping_state']['required'] = false;
	$address_fields['billing_state']['required'] = false;
return $fields;
}

// Change Order Checkout Fields
add_filter("woocommerce_checkout_fields", "order_fields");
function order_fields($fields) {
    $order = array(
        "billing_first_name", 
        "billing_last_name", 
        "billing_address_1", 
        "billing_address_2", 
	"billing_city",
        "billing_postcode",
	"billing_state",
        "billing_country",
        "billing_email", 
        "billing_phone"
    );
    foreach($order as $field)
    {
        $ordered_fields[$field] = $fields["billing"][$field];
    }
    $fields["billing"] = $ordered_fields;
    return $fields;
} 

// Change Order Shipping Fields
add_filter("woocommerce_checkout_fields", "order_shipping_fields");
function order_shipping_fields($fields) {
    $order = array(
        "shipping_first_name", 
        "shipping_last_name",  
        "shipping_address_1", 
        "shipping_address_2", 
	"shipping_city",
        "shipping_postcode",
	"shipping_state",
        "shipping_country", 
	"shipping_company",
    );
    foreach($order as $field)
    {
        $ordered_fields[$field] = $fields["shipping"][$field];
    }
    $fields["shipping"] = $ordered_fields;
    return $fields;
} 

Add FontAwesome to your search button

//* Customize search form input button text
add_filter( 'genesis_search_button_text', 'atp_search_button_text' );
function atp_search_button_text( $text ) {
 
	return esc_attr( '' );
 
}

Add a custom menu in your footer

// Show custom menu in Footer
//add_action( 'genesis_footer', 'custom_menu_in_footer',10 );
function custom_menu_in_footer() {
	$class = 'menu genesis-nav-menu menu-footer';
	$args = array(
		'menu'           => 'Footer Menu', // Enter name of your custom menu here
		'container'      => '',
		'menu_class'     => $class,
		'echo'           => 0,
		'depth'           => 1,
	);
	$nav = wp_nav_menu( $args );
	$nav_markup_open = genesis_markup( array(
		'html5'   => '<nav %s>',
		'xhtml'   => '<div id="nav">',
		'context' => 'nav-footer',
		'echo'    => false,
	) );
	$nav_markup_open .= genesis_structural_wrap( 'menu-footer', 'open', 0 );
	$nav_markup_close  = genesis_structural_wrap( 'menu-footer', 'close', 0 );
	$nav_markup_close .= genesis_html5() ? '</nav>' : '</div>';
	$nav_output = $nav_markup_open . $nav . $nav_markup_close;
	echo $nav_output;
}

Useful Role snippets

function remove_roles(){
//Remove obsolete WP roles if you like with this code
//$wp_roles = new WP_Roles();
//$wp_roles->remove_role("customer");
//$wp_roles->remove_role("premium");
}

function show_role(){  
//$roles = $wp_roles->get_names();
//print_r($roles);
}

function add_new_role(){  
$result = add_role(
    'paid',
    __( 'Paid' ),
    array(
        'read'         => true,  // true allows this capability
        'edit_posts'   => false,
        'delete_posts' => false, // Use false to explicitly deny
    )
);
if ( null !== $result ) {
    echo 'Yay! New role created!';
}
else {
    echo 'Oh... the basic_contributor role already exists.';
}
}

add_filter('woocommerce_get_price', 'custom_price_WPA111772', 10, 2);

        if (has_role_WPA111772('free')){
            //give user 100% off

        }
    }
    return $price;
