Most of these codes should be pasted into wp-content/themes/rey-child/functions.php .

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;
});

Or, if you want to have a strict aspect ratio such as the catalog thumbnails, here’s the custom code:

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 ) ) );
  $width_ratio    = max( 1, get_option( 'woocommerce_thumbnail_cropping_custom_width', '4' ) );
  $height_ratio   = max( 1, get_option( 'woocommerce_thumbnail_cropping_custom_height', '3' ) );
  $size['height'] = absint( Automattic\WooCommerce\Utilities\NumberUtil::round( ( $size['width'] / $width_ratio ) * $height_ratio ) );
  $size['crop']   = 1;
  return $size;
}, 20);

Override WooCommerce’s gallery thumbnail sizes

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() ){

	}
},20);

Remove price from loop & product page

    remove_action('reycore/woocommerce/after_shop_loop_item', 'woocommerce_template_loop_price', 10);

    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);

	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 );

	];

	if( has_term( $category_slugs, 'product_cat', $product->get_id() ) ){
