显示在购物车和结帐中的管理产品页面自定义字段 [英] Admin product pages custom field displayed in Cart and checkout

问题描述

我在 WooCommerce Admin 中的产品页面的常规设置选项卡上创建了一个自定义字段，以插入几天的制造时间.我想在购物车和结帐页面上每个产品名称上方显示此自定义字段值.

这是我的代码:

//插入自定义管理字段函数 woo_add_custom_general_fields() {echo '
';woocommerce_wp_text_input(数组('id' =>'天_制造','标签' =>__( '制造天数', 'woocommerce' ),'占位符' =>'','说明' =>__( '在此处插入', 'woocommerce' ),'类型' =>'数字'，'custom_attributes' =>大批('步骤' =>'任何'，'分钟' =>'1')) );回声'</div>';}add_action('woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields');//保存字段函数 woo_add_custom_general_fields_save( $post_id ){$woocommerce_number_field = $_POST['days_manufacture'];if( !empty( $woocommerce_number_field ) )update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );}add_action('woocommerce_process_product_meta', 'woo_add_custom_general_fields_save');函数 save_days_field( $cart_item_data, $product_id ) {if( isset( $_REQUEST['days_manufacture'] ) ) {$cart_item_data[ 'days_manufacture' ] = get_post_meta( $post->ID, 'days_manufacture',true );/* 下面的语句确保每个添加到购物车的操作都是唯一的行项目 */$cart_item_data['unique_key'] = md5( microtime().rand() );}返回 $cart_item_data;}add_action('woocommerce_add_cart_item_data', 'save_days_field', 10, 2);函数 render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {$custom_items = array();/* Woo 2.4.2 更新 */if( !empty( $cart_data ) ) {$custom_items = $cart_data;}if( isset( $cart_item['days_manufacture'] ) ) {$custom_items[] = array( "name" => 'Days:', "value" => $cart_item['days_manufacture'] );}返回 $custom_items;}add_filter('woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2);

但这不起作用，因为我无法在购物车和结帐页面上显示自定义字段值.

我怎样才能做到这一点?

谢谢

解决方案

我已经测试了您的代码并更正了一些部分，以使该产品自定义字段显示在购物车和结帐页面上.

这是更正后的代码:

//插入自定义管理字段add_action('woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields');函数 woo_add_custom_general_fields() {echo '
';woocommerce_wp_text_input(数组('id' =>'天_制造','标签' =>__( '制造天数', 'woocommerce' ),'占位符' =>'','说明' =>__( '在此处插入', 'woocommerce' ),'类型' =>'数字'，'custom_attributes' =>大批('步骤' =>'任何'，'分钟' =>'1'),) );回声'</div>';}//保存字段add_action('woocommerce_process_product_meta', 'woo_add_custom_general_fields_save');函数 woo_add_custom_general_fields_save( $post_id ){$woocommerce_number_field = $_POST['days_manufacture'];if( !empty( $woocommerce_number_field ) )update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );}//存储自定义字段add_filter('woocommerce_add_cart_item_data', 'save_days_field', 10, 2);函数 save_days_field( $cart_item_data, $product_id ) {$special_item = get_post_meta( $product_id , 'days_manufacture',true );如果(！空($special_item)){$cart_item_data['days_manufacture'] = $special_item;//下面的语句确保每个添加到购物车的操作都是唯一的订单项$cart_item_data['unique_key'] = md5( microtime().rand() );WC()->session->set('days_manufacture', $special_item);}返回 $cart_item_data;}//在购物车和结帐上呈现元数据add_filter('woocommerce_get_item_data', 'rendering_meta_field_on_cart_and_checkout', 10, 2);函数渲染_meta_field_on_cart_and_checkout( $cart_item_data, $cart_item ) {if( isset( $cart_item['days_manufacture'] ) ) {$cart_item_data[] = array( "name" => __( "Days", "woocommerce" ), "value" => $cart_item['days_manufacture'] );}返回 $cart_item_data;}

当然，这会出现在活动子主题(或主题)的 function.php 文件或任何插件文件中.

此代码已经过测试且有效.

I have created a Custom Field in WooCommerce Admin on the general settings tab of product pages, to insert a some days for manufacture. I would like to show this custom field value on cart and checkout pages above the name of each product.

Here is my code:

// Insert a Custom Admin Field
function woo_add_custom_general_fields() {

    echo '<div class="options_group">';

    woocommerce_wp_text_input( array( 
        'id'                => 'days_manufacture', 
        'label'             => __( 'Days for Manufacture', 'woocommerce' ), 
        'placeholder'       => '', 
        'description'       => __( 'Insert here', 'woocommerce' ),
        'type'              => 'number', 
        'custom_attributes' => 
        array(
            'step'  => 'any',
            'min'   => '1'
        ) 
    ) );
    echo '</div>';
}
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );


// Save field
function woo_add_custom_general_fields_save( $post_id ){
    $woocommerce_number_field = $_POST['days_manufacture'];
    if( !empty( $woocommerce_number_field ) )
        update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );
}
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );


function save_days_field( $cart_item_data, $product_id ) {
    if( isset( $_REQUEST['days_manufacture'] ) ) {
        $cart_item_data[ 'days_manufacture' ] = get_post_meta( $post->ID, 'days_manufacture',true );

/* below statement make sure every add to cart action as unique line item */

   $cart_item_data['unique_key'] = md5( microtime().rand() );
    }
    return $cart_item_data;
}
add_action( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );


function render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {
    $custom_items = array();
    /* Woo 2.4.2 updates */
    if( !empty( $cart_data ) ) {
        $custom_items = $cart_data;
    }
    if( isset( $cart_item['days_manufacture'] ) ) {
        $custom_items[] = array( "name" => 'Days:', "value" => $cart_item['days_manufacture'] );
    }
    return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

But this is not working as I can't display the custom field value on cart and checkout pages.

How can I achieve this?

Thanks

解决方案

I have tested your code and corrected some portions to make that product custom field appear on cart and checkout pages.

Here is that corrected code:

// Insert a Custom Admin Field
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );
function woo_add_custom_general_fields() {
    echo '<div class="options_group">';

    woocommerce_wp_text_input( array(
        'id'                => 'days_manufacture',
        'label'             => __( 'Days for Manufacture', 'woocommerce' ),
        'placeholder'       => '',
        'description'       => __( 'Insert here', 'woocommerce' ),
        'type'              => 'number',
        'custom_attributes' => array(
            'step'  => 'any',
            'min'   => '1'
        ),
    ) );

    echo '</div>';
}

// Save the field
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );
function woo_add_custom_general_fields_save( $post_id ){
$woocommerce_number_field = $_POST['days_manufacture'];
if( !empty( $woocommerce_number_field ) )
    update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );
}

// Store custom field
add_filter( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );
function save_days_field( $cart_item_data, $product_id ) {
    $special_item = get_post_meta( $product_id , 'days_manufacture',true );
    if(!empty($special_item)) {
        $cart_item_data[ 'days_manufacture' ] = $special_item;

        // below statement make sure every add to cart action as unique line item
        $cart_item_data['unique_key'] = md5( microtime().rand() );
        WC()->session->set( 'days_manufacture', $special_item );
    }
    return $cart_item_data;
}


// Render meta on cart and checkout
add_filter( 'woocommerce_get_item_data', 'rendering_meta_field_on_cart_and_checkout', 10, 2 );

function rendering_meta_field_on_cart_and_checkout( $cart_item_data, $cart_item ) {
    if( isset( $cart_item['days_manufacture'] ) ) {
        $cart_item_data[] = array( "name" => __( "Days", "woocommerce" ), "value" => $cart_item['days_manufacture'] );
    }
    return $cart_item_data;
}

Naturally, this goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works.
