Useful Genesis Snippets

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.

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_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;
}

	$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;
}
