    ?>
    <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);

作品:

后端:下拉菜单中添加了新的状态，我可以选择我想要的状态。

不起作用:

前端:在单个产品页面上未显示正确状态。

后端:在管理产品列表表上显示新状态

有人可以帮助我吗？

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 );

如果需要，自定义库存状态可以用于您已经可以访问 $product 的 Hook 中。对象或您使用 global $product .

// 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();
    
    // Compare
    if ( $product_stock_status == 'My custom stock status' ) {
        // Etc..
    }
}
