variation custom stock status linking to parent [duplicate] - php

Question

I am using the following code to add new stock statuses in WooCommerce 4+
The new statuses are:
Preorder
Contact us
function add_custom_stock_type() {
?>
<script type="text/javascript">
jQuery(function(){
jQuery('._stock_status_field').not('.custom-stock-status').remove();
});
</script>
<?php
woocommerce_wp_select( array( 'id' => '_stock_status', 'wrapper_class' => 'custom-stock-status', 'label' => __( 'Stock status', 'woocommerce' ), 'options' => array(
'instock' => __( 'Available', 'woocommerce' ), //changed the name
'outofstock' => __( 'Sold out', 'woocommerce' ), //changed the name
'onbackorder' => __( 'Preorder : Pending Distributor release', 'woocommerce' ), //changed the name
'contact' => __( 'Contact us for Availability', 'woocommerce' ), //added new one
'preorder' => __( 'On Preorder: Pending Distributor release', 'woocommerce' ), //added new one
), 'desc_tip' => true, 'description' => __( 'Controls whether or not the product is listed as "in stock" or "out of stock" on the frontend.', 'woocommerce' ) ) );
}
add_action('woocommerce_product_options_stock_status', 'add_custom_stock_type');
function save_custom_stock_status( $product_id ) {
update_post_meta( $product_id, '_stock_status', wc_clean( $_POST['_stock_status'] ) );
}
add_action('woocommerce_process_product_meta', 'save_custom_stock_status',99,1);
function woo_add_custom_general_fields_save_two( $post_id ){
// Select
$woocommerce_select = $_POST['_stock_status'];
if( !empty( $woocommerce_select ) )
update_post_meta( $post_id, '_stock_status', esc_attr( $woocommerce_select ) );
else
update_post_meta( $post_id, '_stock_status', '' );
}
function woocommerce_get_custom_availability( $data, $product ) {
switch( $product->stock_status ) {
case 'instock':
$data = array( 'availability' => __( 'Available', 'woocommerce' ), 'class' => 'in-stock' ); //changed name
break;
case 'outofstock':
$data = array( 'availability' => __( 'Sold Out', 'woocommerce' ), 'class' => 'out-of-stock' ); //changed name
break;
case 'onbackorder':
$data = array( 'availability' => __( 'Preorder : Pending Distributor release', 'woocommerce' ), 'class' => 'onbackorder' ); //changed name
break;
case 'contact':
$data = array( 'availability' => __( 'Contact us for Availability', 'woocommerce' ), 'class' => 'contact' ); //added new one
break;
case 'preorder':
$data = array( 'availability' => __( 'On Preorder : Pending Distributor release', 'woocommerce' ), 'class' => 'preorder' ); //added new one
break;
}
return $data;
}
add_action('woocommerce_get_availability', 'woocommerce_get_custom_availability', 10, 4);
Works:
Backend: The new status is added in the dropdown menu, I can select the status I want
Does not work:
Front end: on single product page is not showing the correct status
Backend: Display the new status on the admin products list table
Someone who can assist me with this?

Last update: 04/22 - Tested in WordPress 5.9.2 & WooCommerce 6.3.1
Code goes in functions.php file of the active child theme (or active theme).
Use woocommerce_product_stock_status_options
instead of woocommerce_product_options_stock_status.
This way you can immediately add a status instead of replace the existing dropdown
Also use woocommerce_get_availability_text & woocommerce_get_availability_class
opposite woocommerce_get_availability.
This way you don't have to add the existing statuses again
// Add new stock status options
function filter_woocommerce_product_stock_status_options( $status ) {
// Add new statuses
$status['pre_order'] = __( 'Pre order', 'woocommerce' );
$status['contact_us'] = __( 'Contact us', 'woocommerce' );
return $status;
}
add_filter( 'woocommerce_product_stock_status_options', 'filter_woocommerce_product_stock_status_options', 10, 1 );
// Availability text
function filter_woocommerce_get_availability_text( $availability, $product ) {
// Get stock status
switch( $product->get_stock_status() ) {
case 'pre_order':
$availability = __( 'Pre order', 'woocommerce' );
break;
case 'contact_us':
$availability = __( 'Contact us', 'woocommerce' );
break;
}
return $availability;
}
add_filter( 'woocommerce_get_availability_text', 'filter_woocommerce_get_availability_text', 10, 2 );
// Availability CSS class
function filter_woocommerce_get_availability_class( $class, $product ) {
// Get stock status
switch( $product->get_stock_status() ) {
case 'pre_order':
$class = 'pre-order';
break;
case 'contact_us':
$class = 'contact-us';
break;
}
return $class;
}
add_filter( 'woocommerce_get_availability_class', 'filter_woocommerce_get_availability_class', 10, 2 );
Use woocommerce_admin_stock_html to display the new stock status on the admin products list table
// Admin stock html
function filter_woocommerce_admin_stock_html( $stock_html, $product ) {
// Simple
if ( $product->is_type( 'simple' ) ) {
// Get stock status
$product_stock_status = $product->get_stock_status();
// Variable
} elseif ( $product->is_type( 'variable' ) ) {
foreach( $product->get_visible_children() as $variation_id ) {
// Get product
$variation = wc_get_product( $variation_id );
// Get stock status
$product_stock_status = $variation->get_stock_status();
/*
Currently the status of the last variant in the loop will be displayed.
So from here you need to add your own logic, depending on what you expect from your custom stock status.
By default, for the existing statuses. The status displayed on the admin products list table for variable products is determined as:
- Product should be in stock if a child is in stock.
- Product should be out of stock if all children are out of stock.
- Product should be on backorder if all children are on backorder.
- Product should be on backorder if at least one child is on backorder and the rest are out of stock.
*/
}
}
// Stock status
switch( $product_stock_status ) {
case 'pre_order':
$stock_html = '<mark class="pre-order" style="background:transparent none;color:#33ccff;font-weight:700;line-height:1;">' . __( 'Pre order', 'woocommerce' ) . '</mark>';
break;
case 'contact_us':
$stock_html = '<mark class="contact-us" style="background:transparent none;color:#cc33ff;font-weight:700;line-height:1;">' . __( 'Contact us', 'woocommerce' ) . '</mark>';
break;
}
return $stock_html;
}
add_filter( 'woocommerce_admin_stock_html', 'filter_woocommerce_admin_stock_html', 10, 2 );
Optional: if desired, the custom stock status can be used in hooks where you already have access to the $product object or you can use global $product.
1) No access to the $product object, use global $product as is the case for example with the woocommerce_shop_loop_item_title or the woocommerce_single_product_summary hook
function woocommerce_my_callback() {
// An example based on global $product
// Get the global product object
global $product;
// Is a WC product
if ( is_a( $product, 'WC_Product' ) ) {
// Get stock status
$product_stock_status = $product->get_stock_status();
// Use this line during testing, delete afterwards!
echo '<p style="color:red;font-size:20px;">DEBUG INFORMATION = ' . $product_stock_status . '</p>';
// Compare
if ( $product_stock_status == 'My custom stock status' ) {
// Etc..
}
}
}
add_action( 'woocommerce_shop_loop_item_title', 'woocommerce_my_callback', 10 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_my_callback', 10 );
2) Access to the $product object, because it's passed by default to the callback function. As is the case for example with the woocommerce_get_price_html hook
function filter_woocommerce_get_price_html( $price, $product ) {
// Is a WC product
if ( is_a( $product, 'WC_Product' ) ) {
// Get stock status
$product_stock_status = $product->get_stock_status();
// Use this line during testing, delete afterwards!
echo '<p style="color:red;font-size:20px;">DEBUG INFORMATION = ' . $product_stock_status . '</p>';
// Compare
if ( $product_stock_status == 'My custom stock status' ) {
// Etc..
// $price .= ' my text';
}
}
return $price;
}
add_filter( 'woocommerce_get_price_html', 'filter_woocommerce_get_price_html', 10, 2 );

In addition to filters provided by 7uc1f3r woocommerce_product_export_product_column_stock_status filter is required to display custom stock status in exported products CSV file:
function add_custom_stock_csv_data( $_, $product ) {
$status = $product->get_stock_status( 'edit' );
switch( $status ) {
case 'pre_order':
case 'contact_us':
return $status;
case 'onbackorder':
return 'backorder';
case 'instock':
return 1;
default:
return 0;
}
}
add_filter( 'woocommerce_product_export_product_column_stock_status', 'add_custom_stock_csv_data', 10, 2 );
