更换产品“按需交货”。到Woocommerce中的自定义字段值 [英] Replace product "on backorder" to a custom field value in Woocommerce

问题描述

首先，感谢您查看此问题。
我已经搜索并遇到了许多类似的问题，但是我还没有找到完美的解决方法。

Firstly, thanks for viewing this question. I've searched and gone through many similar questions however i've not managed to find a perfect fix.

我使用wordpress / woocommerce建立了一个网站，但是我们大多数产品的交货时间都是固定的，因此所有产品都处于延期交货-允许状态。我想看看是否有可能在每个产品上创建一个自定义字段，并替换按需订购文本以显示该自定义字段，而不是在每个产品页面上显示按需订购。

Im setting up a website using wordpress/woocommerce, however most of our products have a set lead time therefore everything is on "back order - allow" status. Instead of showing "on backorder" on each product page, I wanted to see if it was possible to create a custom field in each product and replace the "on backorder" text to show that custom field.

当前，我一直在使用以下代码来更改每种产品的文本，但是，并非所有产品都在特定的交货时间上。

Currently, i've been using the following code that just changes the text for every product however, not all products are on that specific lead time.

add_filter( 'woocommerce_get_availability', 'backorder_text', 10, 2);
function backorder_text($available) {
 return str_replace('Available on backorder', 'Approx lead time: 2-4 working weeks', $available);
}

我很高兴我需要在每个产品中使用设置时间，但我不完全确定如何将每个产品的特定自定义字段链接到该php代码（或更确切地说，是否实际上可行）。

I appreciate I would need to set up a custom field in each product with the set time, but i'm not entirely sure how to link that specfic custom field per each product to that php code (or rather, whether its actually possible).

任何帮助将是很棒的-即使它告诉我无法完成！

Any help would be fantastic - even if its to tell me it can't be done!

推荐答案

这可以通过以下操作完成代码，它也将处理产品和产品变体：

This can be done with the following code, that will handle products and product variation too:

// Add a custom field in admin product edit pages - inventory tab
add_action( 'woocommerce_product_options_stock_fields', 'add_product_options_stock_custom_field', 20 );
function add_product_options_stock_custom_field() {
    global $product_object, $post;

    woocommerce_wp_text_input( array(
        'id'          => '_backorder_text',
        'type'        => 'text',
        'label'       => __( 'Backorders text', 'woocommerce' ),
        'description' => __( 'Backorders text. Add a custom backorders text to be displayed when products are on backorders.', 'woocommerce' ),
        'desc_tip'    => true,
    ) );

    // jQuery: HIDE the fied if backorders are not enabled
    ?>
    <script type="text/javascript">
    jQuery( function($){
        var a = 'select#_backorders',
            b = 'p._backorder_text_field';

        if( $(a).val() === 'no' )
            $(b).hide();

        $(a).on('change blur', function(){
            if( $(a).val() === 'no' )
                $(b).hide();
            else
                $(b).show();
        });
    });
    </script>
    <?php
}

// Save the custom field value from admin product edit pages - inventory tab
add_action( 'woocommerce_process_product_meta', 'save_product_options_stock_custom_field', 20, 1 );
function save_product_options_stock_custom_field( $product_id ) {
    if ( isset( $_POST['_backorder_text'] ) )
        update_post_meta( $product_id, '_backorder_text', sanitize_text_field( $_POST['_backorder_text'] ) );
}

// Variations: Add a custom field in admin variation options inventory
add_action( 'woocommerce_variation_options_inventory', 'add_variation_settings_fields', 20, 3 );
function add_variation_settings_fields( $loop, $variation_data, $variation_post ) {

    woocommerce_wp_text_input( array(
        'id'            => '_backorder_text'.$loop,
        'name'          => '_backorder_text['.$loop.']',
        'value'         => get_post_meta( $variation_post->ID, '_backorder_text', true ),
        'type'          => 'text',
        'label'         => __( 'Backorders text', 'woocommerce' ),
        'description'   => __( 'Backorders text. Add a custom backorders text to be displayed when products are on backorders.', 'woocommerce' ),
        'desc_tip'      => true,
        'wrapper_class' => 'form-row form-row-first',
    ) );
}

// Variations: Save a custom field value from admin variation options inventory
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );
function save_variation_settings_fields( $variation_id, $i ) {
    if( isset( $_POST['_backorder_text'][$i] ) )
        update_post_meta( $variation_id, '_backorder_text', sanitize_text_field( $_POST['_backorder_text'][$i] ) );
}

add_filter( 'woocommerce_get_availability', 'custom_on_backorder_text', 10, 2 );
function custom_on_backorder_text( $availability, $product ) {
    $backorder_text = get_post_meta( $product->get_id(), '_backorder_text', true );

    if( $availability['class'] === 'available-on-backorder' && ! empty( $backorder_text ) )
        $availability['availability'] = $backorder_text;

    return $availability;
}

代码进入活动子主题（或活动主题）的function.php文件）。经过测试并有效。

Code goes in function.php file of your active child theme (or active theme). Tested and works.

对于所有产品（可变产品除外，请参阅下文），您将获得：

For all products (except variable products, see after) you will get:
