Show Wishlist icon on products when in Catalogue Mode

Catalogue mode* is when Ecommerce functionality is disabled.

add_action('wp', function(){
	if( class_exists('WooCommerce') && class_exists('TInvWL_Public_AddToWishlist') && is_product() ) {
		$product = wc_get_product();
		if( ! $product->is_purchasable() && ($product->get_regular_price() || $product->get_sale_price()) ) {
			add_action( 'woocommerce_single_product_summary', function(){
				echo do_shortcode("[ti_wishlists_addtowishlist]");
			}, 20 );
		}
	}
});

Force custom height & cropping in product page images

Replace 400 height with another size. It might be needed to regenerate, so you can try accessing WooCommerce > Status > Tools > Regenerate eg: https://d.pr/i/aKwJ8K .

add_filter('woocommerce_get_image_size_single', function($size){
  $size['width']  = absint( wc_get_theme_support( 'single_image_width', get_option( 'woocommerce_single_image_width', 600 ) ) );
  $size['height'] = 400;
  $size['crop']   = 1;
  return $size;
});

Replace 180 with another size. It might be needed to regenerate, so you can try accessing WooCommerce > Status > Tools > Regenerate eg: https://d.pr/i/aKwJ8K .

add_filter('woocommerce_get_image_size_gallery_thumbnail', function ($size){
	$cropping['width'] = max( 1, get_option( 'woocommerce_thumbnail_cropping_custom_width', '4' ) );
	$cropping['height'] = max( 1, get_option( 'woocommerce_thumbnail_cropping_custom_height', '3' ) );
	$size['width']  = 180;
	$size['height'] = ($cropping['height'] / $cropping['width']) * $size['width'];
	$size['crop']   = 1;
    return $size;
}, 10);

Enable Home link in product page breadcrumbs

add_filter( 'woocommerce_breadcrumb_defaults', function($args){
	if( is_product() ){
		$args['home'] = _x( 'Home', 'breadcrumb', 'rey-core' );
		return $args;
	}
},20);

Slow Customizer? Disable the preview iframe.

add_action('customize_controls_print_footer_scripts', function(){
	?>
	<script>
		document.addEventListener('DOMContentLoaded', function(){
			document.getElementById('customize-preview').remove();
		});
	</script>
	<?php
});

Remove price from loop & product page

add_action('wp', function(){
    remove_action('reycore/woocommerce/after_shop_loop_item', 'woocommerce_template_loop_price', 10);
    remove_action('woocommerce_after_shop_loop_item', 'woocommerce_template_loop_price', 60);
    remove_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10);
    remove_action('woocommerce_single_product_summary', 'woocommerce_template_single_price', 10);
});

Add WooCommerce Multilingual Currency Switcher into Default Header


// Adds the currency switcher in the header
add_action('rey/header/row', function(){

    // This shortcode adds the Currency switcher
    // but too much text is shown
    //echo do_shortcode('[currency_switcher]');

    // instead show only what matters
    do_action('wcml_currency_switcher', array(
        'format' => '%code% (%symbol%)'
    ));

}, 70);

And also some fine tuning CSS in Customizer > Additional CSS

.wcml_currency_switcher {
    margin-left: 1.5rem;
    width: auto;
}

These codes apply for the Default header, when it’s non Global Section. If you’re using a Header Global Section, simply add a Shortcode element into the Header section and paste the shortcode eg: [currency_switcher] .

Apply “zero-px” hack for outdated minifiers in caching plugins

Some caching plugin css minifiers are trimming “0px” values and remove the unit, leaving it as “0” only. This breaks CSS variables and calc() functions in CSS. To prevent this, i made a “hack” until these minifiers will get updated to the latest browser standards. To enable it, use this code below.

add_action('wp_head', function(){
	?>
	<script>
		document.documentElement.style.setProperty('--zero-px', '0px');
	</script>
	<?php
}, 0);

add_filter('woocommerce_is_purchasable', function( $is_purchasable, $product ) {

	$products_ids = [ 10, 11 ];

	if( in_array($product->get_id(), $products_ids, true) ) {
		return false;
	}

	return $is_purchasable;
}, 10, 2 );

// Disable products from category "Uncategorized" from being purchased no matter what
add_filter('woocommerce_is_purchasable', function ( $is_purchasable, $product ) {

	$products_categories = [ 'uncategorized' ];

	if( has_term( $products_categories, 'product_cat', $product->get_id() ) ) {
		return false;
	}

	return $is_purchasable;
}, 10, 2 );

Add price suffix per products belonging to certain categories

add_filter( 'woocommerce_get_price_suffix', function ( $html, $product, $price, $qty ){

	$category_slugs = [
		'down-coats-vests',
		'sweatshirts-hoodies'
	];

	if( has_term( $category_slugs, 'product_cat', $product->get_id() ) ){
		$html .= '<span>per square</span>';
	}

    return $html;
}, 99, 4 );

Show a generic global section under Place order button in Checkout page

add_action('woocommerce_review_order_after_payment', function(){
	// replace 2700 with the global section id you want
	echo do_shortcode('[rey_global_section id="2700"]');
} );

Move Filter offcanvas panel on the left side of the screen

.rey-filterPanel-wrapper {
    left: 0;
    right: auto;
    transform: translateX(-100%);
}

@media (min-width: 1025px){
   .--filter-panel-active .rey-siteContent {
        transform: translateX(100px);
    }
}

Sticky Add to cart bar, add finish point

The bar will show up after the add to cart button has exited the viewport and will show up til the end of the page. If you want the bar to show up until a certain point, you can use this code below.

Either add a fixed number (eg 2000) or a css class selector.

add_filter('reycore/module/sticky_add_to_cart_settings', function($settings){

	// add a class of an element
	$settings['finish_point'] = '.related.products';

	// add a fixed value
	// $settings['finish_point'] = '2000';

	return $settings;
}, 20);

Add product page subtitle

You will need to make use of Advanced Custom Fields plugin. Here is a video explaining how to create a custom ACF field https://d.pr/v/MDSNIx .

And below is the code you need to add into the child theme’s functions.php to display the content.

add_action('woocommerce_single_product_summary', function(){
	global $product;
	if( class_exists('ACF') && $product && ($subtitle = get_field('prod_extra__subtitle', $product->get_id())) ){
		printf('<h4 class="product-subtitle">%s</h4>', $subtitle);
	}
}, 5);

    Hi, is it possible to put the product title above the product gallery for mobile only?

    Desktop is great but I’d like to compact mobile in that way.

    1. mariushoria[ Post Author ]

      Hi Eloy,

      Unfortunately no, because the Title’s tag is inside another blocks eg: https://d.pr/i/YoQMyL . The only way could be by adding a new title tag before the mobile gallery tag and show it on mobiles only, while the Summary’s title will be hidden on mobiles. The problem here is that the title has an H1 tag and i’m not sure how this would perform in SEO terms.
