在 Woocommerce 中设置产品级别的最小、最大和步骤数量 [英] Set quantity minimum, maximum and step at product level in Woocommerce

问题描述

我正在使用 "

当复选框被选中 (字段可见且数量设置已启用):

我已将唯一自定义字段中的所有设置合并为值的索引数组，以提高性能.

自 WooCommerce 版本 3 以来，情况发生了很大变化，因此我进行了一些更改，以增强代码并将其更新为更新的内容.

<块引用>

也适用于 Ajax 添加到购物车的简单产品、可变产品的产品变体以及购物车数量输入字段.

全部代码:

//在管理产品页面上显示数量设置字段add_action('woocommerce_product_options_pricing', 'wc_qty_add_product_field');函数 wc_qty_add_product_field() {全球 $product_object;$values = $product_object->get_meta('_qty_args');echo '</div><div class="options_group数量 hide_if_grouped"><style>div.qty-args.hidden { display:none;}</style>';woocommerce_wp_checkbox( array(//复选框.'id' =>'qty_args','标签' =>__( '数量设置', 'woocommerce' ),'价值' =>空($值)?'否' : '是','说明' =>__( '启用此项以显示和启用附加数量设置字段.', 'woocommerce' ),) );echo '<div class="qty-args hidden">';woocommerce_wp_text_input(数组('id' =>'qty_min','类型' =>'数字'，'标签' =>__( '最小数量', 'woocommerce-max-quantity' ),'占位符' =>'','desc_tip' =>'真的'，'说明' =>__( '设置最小允许数量限制(大于 0 的数字).', 'woocommerce' ),'custom_attributes' =>数组(步"=>任何"，最小"=>0")，'价值' =>isset($values['qty_min']) &&$values['qty_min'] >0 ?(int) $values['qty_min'] : 0,) );woocommerce_wp_text_input(数组('id' =>'qty_max','类型' =>'数字'，'标签' =>__( '最大数量', 'woocommerce-max-quantity'),'占位符' =>'','desc_tip' =>'真的'，'说明' =>__( '设置最大允许数量限制(大于 0 的数字).值-1"是无限制的', 'woocommerce' ),'custom_attributes' =>数组(步"=>任何"，最小"=>-1")，'价值' =>isset($values['qty_max']) &&$values['qty_max'] >0 ?(int) $values['qty_max'] : -1,) );woocommerce_wp_text_input(数组('id' =>'数量_步','类型' =>'数字'，'标签' =>__( '数量步骤', 'woocommerce-quantity-step' ),'占位符' =>'','desc_tip' =>'真的'，'说明' =>__( '可选.设置数量步长(大于 0 的数字)', 'woocommerce' ),'custom_attributes' =>数组(步"=>任何"，最小"=>1")，'价值' =>isset($values['qty_step']) &&$values['qty_step'] >1 ?(int) $values['qty_step'] : 1,) );回声'</div>';}//显示/隐藏设置字段(管理产品页面)add_action('admin_footer', 'product_type_selector_filter_callback');函数 product_type_selector_filter_callback() {全球 $pagenow, $post_type;if( in_array($pagenow, array('post-new.php', 'post.php') ) && $post_type === 'product' ) :?><脚本>jQuery(函数($){if( $('input#qty_args').is(':checked') && $('div.qty-args').hasClass('hidden') ) {$('div.qty-args').removeClass('隐藏')}$('input#qty_args').click(function(){if( $(this).is(':checked') && $('div.qty-args').hasClass('hidden')) {$('div.qty-args').removeClass('隐藏');} else if( ! $(this).is(':checked') && ! $('div.qty-args').hasClass('hidden')) {$('div.qty-args').addClass('隐藏');}});});<?php万一;}//保存数量设置字段值add_action('woocommerce_admin_process_product_object', 'wc_save_product_quantity_settings');函数 wc_save_product_quantity_settings( $product ) {如果( isset($_POST['qty_args'])){$values = $product->get_meta('_qty_args');$product->update_meta_data( '_qty_args', array('qty_min' =>isset($_POST['qty_min']) &&$_POST['qty_min'] >0 ?(int) wc_clean($_POST['qty_min']) : 0,'qty_max' =>isset($_POST['qty_max']) &&$_POST['qty_max'] >0 ?(int) wc_clean($_POST['qty_max']) : -1,'qty_step' =>isset($_POST['qty_step']) &&$_POST['qty_step'] >1 ?(int) wc_clean($_POST['qty_step']) : 1,) );} 别的 {$product->update_meta_data('_qty_args', array());}}//前端操作中的数量设置add_filter('woocommerce_quantity_input_args', 'filter_wc_quantity_input_args', 99, 2);函数 filter_wc_quantity_input_args( $args, $product ) {if ( $product->is_type('variation') ) {$parent_product = wc_get_product( $product->get_parent_id() );$values = $parent_product->get_meta('_qty_args');} 别的 {$values = $product->get_meta('_qty_args');}如果(！空($values)){//最小值如果 ( isset( $values['qty_min'] ) && $values['qty_min'] > 1 ) {$args['min_value'] = $values['qty_min'];如果(！is_cart()){$args['input_value'] = $values['qty_min'];//起始值}}//最大值如果 ( isset( $values['qty_max'] ) && $values['qty_max'] > 0 ) {$args['max_value'] = $values['qty_max'];如果 ( $product->managing_stock() && ! $product->backorders_allowed() ) {$args['max_value'] = min( $product->get_stock_quantity(), $args['max_value'] );}}//步长值if ( isset( $values['qty_step'] ) && $values['qty_step'] > 1 ) {$args['step'] = $values['qty_step'];}}返回 $args;}//Ajax 添加到购物车，设置最小数量"；作为商店和档案页面上的数量add_filter('woocommerce_loop_add_to_cart_args', 'filter_loop_add_to_cart_quantity_arg', 10, 2);函数 filter_loop_add_to_cart_quantity_arg( $args, $product ) {$values = $product->get_meta('_qty_args');如果(！空($values)){//最小值如果 ( isset( $values['qty_min'] ) && $values['qty_min'] > 1 ) {$args['quantity'] = $values['qty_min'];}}返回 $args;}//前端操作中的数量设置(对于可变产品及其变体)add_filter('woocommerce_available_variation', 'filter_wc_available_variation_price_html', 10, 3);函数 filter_wc_available_variation_price_html( $data, $product, $variation ) {$values = $product->get_meta('_qty_args');如果(！空($values)){如果 ( isset( $values['qty_min'] ) && $values['qty_min'] > 1 ) {$data['min_qty'] = $values['qty_min'];}如果 ( isset( $values['qty_max'] ) && $values['qty_max'] > 0 ) {$data['max_qty'] = $values['qty_max'];if ( $variation->managing_stock() && ! $variation->backorders_allowed() ) {$data['max_qty'] = min( $variation->get_stock_quantity(), $data['max_qty'] );}}}返回 $data;}

代码位于活动子主题(或活动主题)的 functions.php 文件中.经测试有效.

I'm using "set minimum and maximum allowable product quantities to be added in WooCommerce Cart" to require a minimum and maximum quantity order.

Now, i need to impose for several products (not all) a mulitple quantity. For example : 6 bottles, 12 bottles, 18 bottles (multiple of 6) or for other 12 bottles, 24 bottles (multiple of 12)

I found a solution but it's for every product with a unique value and I cant' manage it in the back office for each product individually. I have to manage the multiple quantity in Backoffice.

Thank you if you can help me

解决方案

Updated December 2020

The following revisited code will allow in addition to handle quantity steps.

I have changed quantity fields settings location to "General" settings tab.

I have added a checkbox that enables or disables those additional quantity settings at product level (showing or hiding the setting fields dynamically):

When checkbox unchecked (fields are not visible and quantity settings are disabled):

When checkbox is checked (fields are visible and quantity settings are enabled):

I have merged all settings in a unique custom field as an indexed array of values, to improve performance.

Since WooCommerce version 3, things have changed a lot, so I have made some changes enhancing and updating code to something more newer.

Also works nicely on Ajax add to cart for simple products, for product variations from variable products and also on the cart quantity input field.

All the code:

// Displaying quantity setting fields on admin product pages
add_action( 'woocommerce_product_options_pricing', 'wc_qty_add_product_field' );
function wc_qty_add_product_field() {
    global $product_object;

    $values = $product_object->get_meta('_qty_args');

    echo '</div><div class="options_group quantity hide_if_grouped">
    <style>div.qty-args.hidden { display:none; }</style>';

    woocommerce_wp_checkbox( array( // Checkbox.
        'id'            => 'qty_args',
        'label'         => __( 'Quantity settings', 'woocommerce' ),
        'value'         => empty($values) ? 'no' : 'yes',
        'description'   => __( 'Enable this to show and enable the additional quantity setting fields.', 'woocommerce' ),
    ) );

    echo '<div class="qty-args hidden">';

    woocommerce_wp_text_input( array(
            'id'                => 'qty_min',
            'type'              => 'number',
            'label'             => __( 'Minimum Quantity', 'woocommerce-max-quantity' ),
            'placeholder'       => '',

            'description'       => __( 'Set a minimum allowed quantity limit (a number greater than 0).', 'woocommerce' ),
            'custom_attributes' => array( 'step'  => 'any', 'min'   => '0'),
            'value'             => isset($values['qty_min']) && $values['qty_min'] > 0 ? (int) $values['qty_min'] : 0,
    ) );

    woocommerce_wp_text_input( array(
            'id'                => 'qty_max',

            'custom_attributes' => array( 'step'  => 'any', 'min'   => '-1'),
            'value'             => isset($values['qty_max']) && $values['qty_max'] > 0 ? (int) $values['qty_max'] : -1,
    ) );

    woocommerce_wp_text_input( array(

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