How to add variation stock status to Woocommerce product variation dropdown
(4 answers)
Closed 4 years ago.
I Would like next to variation to show "Out of Stock" when product variation is out of stock. Below, I am using the code from this answer:
add_filter( 'woocommerce_variation_option_name',
'customizing_variations_terms_name', 10, 1 );
function customizing_variations_terms_name( $term_name ){
if(is_admin())
return $term_name;
global $product;
$second_loop_stoped = false;
// Get available product variations
$product_variations = $product->get_available_variations();
// Iterating through each available product variation
foreach($product_variations as $variation){
$variation_id = $variation['variation_id'];
$variation_obj = new WC_Product_Variation( $variation_id );
## WOOCOMMERCE RETRO COMPATIBILITY ##
if ( version_compare( WC_VERSION, '3.0', '<' ) ) # BEFORE Version 3 (older)
{
$stock_status = $variation_obj->stock_status;
$stock_qty = intval($variation_obj->stock);
// The attributes WC slug key and slug value for this variation
$attributes_arr = $variation_obj->get_variation_attributes();
}
else # For newest verions: 3.0+ (and Up)
{
$stock_status = $variation_obj->get_stock_status();
$stock_qty = $variation_obj->get_stock_quantity();
// The attributes taxonomy key and slug value for this variation
$attributes_arr = $variation_obj->get_attributes();
}
if(count($attributes_arr) != 1) // Works only for 1 attribute set in the product
return $term_name;
// Get the terms for this attribute
foreach( $attributes_arr as $attr_key => $term_slug){
// Get the attribute taxonomy
$term_key = str_replace('attribute_', '', $attr_key );
// get the corresponding term object
$term_obj = get_term_by( 'slug', $term_slug, $term_key );
if( $term_obj->name == $term_name ){ // If the term name matches we stop the loops
$second_loop_stoped = true;
break;
}
}
if($second_loop_stoped)
break;
}
if( $stock_qty>0 )
return $term_name .= ' - ' . $stock_status . ' ('.$stock_qty.')';
else
return $term_name .= ' - ' . $stock_status;
}
but when test on my site, it show "Out of Stock" for all variations i have on selected product. For example on this product it show "Out of Stock" for all variations i have, but in fact, only variation "50 ליטר" is in real "Out Of Stock". other variations are In Stock ! I using Woocommerce 3.3.5 version. Can someone to tell me what i need to do to show out of stock next to variations if product is out of stock for real, because i m using radio buttons as replacement for standard dropdown button from Woocommerce.

Seems over complicated, I managed to do it this way. Seems to work, displays out of stock for the correct variations when I tested it.
add_filter( 'woocommerce_variation_option_name', 'customizing_variations_terms_name', 10, 1 );
function customizing_variations_terms_name( $term_name ) {
global $product;
// Get available product variations
$product_variations = $product->get_available_variations();
// product_variation terms are normalized to lowercase with
// spaces replaced by dashes.
// if your term name contains capital letters or spaces i.e. 'SIZE 6'
// the product variation will be lowercase with dashes, i.e. 'size-6'
/*
$term_name = str_replace(' ', '-', strtolower($term_name));
*/
foreach ( $product_variations as $product_variation ) {
if( isset( $product_variation['attributes'] ) ) {
$key = array_search($term_name, $product_variation['attributes']);
if( $key !== false && ! $product_variation['is_in_stock'] ) {
return $term_name . ' - Out of Stock';
}
}
}
return $term_name;
}
In addition to this you can grey out the product so they can't select it if that's something that are after.
add_filter( 'woocommerce_variation_is_active', 'grey_out_variations_when_out_of_stock', 10, 2 );
function grey_out_variations_when_out_of_stock( $grey_out, $variation ) {
if ( ! $variation->is_in_stock() )
return false;
return true;
}
