我需要检查客户是否早些时候在WooCommerce中购买了特定产品。
情况是这样:除非客户较早购买了产品“ a”或“ b”,否则客户将无法购买产品“ c”,“ d”,“ e”。
如果客户较早购买了产品“ a”或“ b”,则激活产品“ c”,“ d”和“ e”的购买按钮,并允许他们购买。
[如果他们以前没有购买过“ a”或“ b”,将不允许他们购买“ c”,“ d”,“ e”,并且取消了购买按钮。
我该如何实现?
谢谢。
处理多个产品ID的更简化的改进代码版本in HERE
更新 (Woocommerce 3+的兼容性)
是的,如果当前客户已经购买了特定定义的产品ID,则可以编写一个条件函数返回“ true”。 此代码位于您的活动子主题或主题的function.php文件中。
这里是条件函数:
function has_bought_items() {
$bought = false;
// Set HERE ine the array your specific target product IDs
$prod_arr = array( '21', '67' );
// Get all customer orders
$customer_orders = get_posts( array(
'numberposts' => -1,
'meta_key' => '_customer_user',
'meta_value' => get_current_user_id(),
'post_type' => 'shop_order', // WC orders post type
'post_status' => 'wc-completed' // Only orders with status "completed"
) );
foreach ( $customer_orders as $customer_order ) {
// Updated compatibility with WooCommerce 3+
$order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
$order = wc_get_order( $customer_order );
// Iterating through each current customer products bought in the order
foreach ($order->get_items() as $item) {
// WC 3+ compatibility
if ( version_compare( WC_VERSION, '3.0', '<' ) )
$product_id = $item['product_id'];
else
$product_id = $item->get_product_id();
// Your condition related to your 2 specific products Ids
if ( in_array( $product_id, $prod_arr ) )
$bought = true;
}
}
// return "true" if one the specifics products have been bought before by customer
return $bought;
}
此代码已经过测试并且可以正常工作。
用法:例如,您可以在以前复制到活动子主题或主题的某些WooCommerce templates中使用它:
add-to-cart
按钮相关的商店页面的模板为loop/add-to-cart.php
。 loop/add-to-cart.php
add-to-cart
中,具体取决于您的产品类型。(上方):
single-product/add-to-cart
folder这里是到[商店页面上的完整的应用示例
single-product/add-to-cart
按钮模板:// Replace the numbers by your special restricted products IDs
$restricted_products = array( '20', '32', '75' );
// compatibility with WC +3
$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;
// customer has NOT already bought a specific product for this restricted products
if ( !has_bought_items() && in_array( $product_id, $restricted_products ) ) {
// Displaying an INACTIVE add-to-cart button (With a custom text, style and without the link).
// (AND optionally) an explicit message for example.
// ALL OTHER PRODUCTS OR RESTRICTED PRODUCTS IF COSTUMER HAS ALREADY BOUGHT SPECIAL PRODUCTS
} else {
// place for normal Add-To-Cart button code here
}
文件中的您将使用活动子主题或主题的
add-to-cart
<?php
/**
* Loop Add to Cart
*
* This template can be overridden by copying it to yourtheme/woocommerce/loop/add-to-cart.php.
*
* HOWEVER, on occasion WooCommerce will need to update template files and you
* (the theme developer) will need to copy the new files to your theme to
* maintain compatibility. We try to do this as little as possible, but it does
* happen. When this occurs the version of the template file will be bumped and
* the readme will list any important changes.
*

*/
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
global $product;
// Replace the numbers by your special restricted products IDs
$restricted_products = array( '37', '53', '70' );
// compatibility with WC +3
$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;
if ( !has_bought_items() && in_array( $product_id, $restricted_products ) ) {
echo '<a class="button greyed_button">' . __("Disabled", "your_theme_slug") . '</a>';
echo '<br><span class="greyed_button-message">' . __("Your message goes here…", "your_theme_slug") . '</span>';
} else {
echo apply_filters( 'woocommerce_loop_add_to_cart_link',
sprintf( '<a rel="nofollow" href="%s" data-quantity="%s" data-product_id="%s" data-product_sku="%s" class="%s">%s</a>',
esc_url( $product->add_to_cart_url() ),
esc_attr( isset( $quantity ) ? $quantity : 1 ),
esc_attr( $product_id ),
esc_attr( $product->get_sku() ),
esc_attr( isset( $class ) ? $class : 'button' ),
esc_html( $product->add_to_cart_text() )
),
$product );
}
类来设置非活动按钮的样式。与greyed_button
类的消息相同。 [2020更新: 现在通过帐单电子邮件处理来宾用户。
这是一个新的增强的轻量级条件函数,部分基于内置的woocommerce函数新版本紧凑,轻便,更快并且与woocommerce的所有版本兼容((从2.4及更高版本开始)
style.css
源代码。
或计费电子邮件有2个可选参数:
greyed_button-message
将允许您:指定已定义的用户ID
- ((当当前登录的用户不使用时)
wc_customer_bought_product
wc_customer_bought_product
此代码已经在WooCommerce 3+上进行了测试,并且可以正常工作(它也可以在以前的版本上工作。)>代码在您的活动子主题(或主题)的function.php文件中,或者在任何插件文件中。
示例1
(已登录客户):检测当前用户是否购买了已定义的产品之一。[[(产品ID必须是数组)$user_var
示例2
(对于已定义的[[用户ID]]检测已定义的用户是否购买了其中一个已定义的产品((需要在数组中设置产品ID)] >>
$product_ids
如果未定义function has_bought_items( $user_var = 0, $product_ids = 0 ) {
global $wpdb;
// Based on user ID (registered users)
if ( is_numeric( $user_var) ) {
$meta_key = '_customer_user';
$meta_value = $value == 0 ? (int) get_current_user_id() : (int) $user_var;
}
// Based on billing email (Guest users)
else {
$meta_key = '_billing_email';
$meta_value = sanitize_email( $user_var );
}
$paid_statuses = array_map( 'esc_sql', wc_get_is_paid_statuses() );
$product_ids = is_array( $product_ids ) ? implode(',', $product_ids) : $product_ids;
$line_meta_value = $product_ids != ( 0 || '' ) ? 'AND woim.meta_value IN ('.$product_ids.')' : 'AND woim.meta_value != 0';
// Count the number of products
$count = $wpdb->get_var( "
SELECT COUNT(p.ID) FROM {$wpdb->prefix}posts AS p
INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id
INNER JOIN {$wpdb->prefix}woocommerce_order_items AS woi ON p.ID = woi.order_id
INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
WHERE p.post_status IN ( 'wc-" . implode( "','wc-", $paid_statuses ) . "' )
AND pm.meta_key = '$meta_key'
AND pm.meta_value = '$meta_value'
AND woim.meta_key IN ( '_product_id', '_variation_id' ) $line_meta_value
" );
// Return true if count is higher than 0 (or false)
return $count; // > 0 ? true : false;
}
并且当前用户未登录,则此函数将返回// Define the targeted Products IDs
$product_ids = array( 38, 41, 85, 95 );
if( has_bought_items( '', $product_ids ) )
echo "<p>You have already purchased one of this products</p>";
else
echo "<p>You have not yet purchased one of this products</p>";
。(对于[guest用户]用户)检测示例3
guest用户
是否已从其计费电子邮件购买了其中一种定义的产品// Define the user ID
$user_id = 85;
// Define the targeted Products IDs
$product_ids = array( 38, 41, 85, 95 );
if( has_bought_items( $user_id, $product_ids ) )
echo "<p>This user have already purchased one of this products</p>";
else
echo "<p>This user have not yet purchased one of this products</p>";
如果未定义$user_id
并且当前用户未登录,则此函数将返回false
。示例4 (已登录客户):检测
当前用户
是否已经购买了商品// Define guest Billing email (string)
$user_email = '[email protected]';
// Define the targeted Products IDs
$product_ids = array( 38, 41, 85, 95 );
if( has_bought_items( $user_email, $product_ids ) )
echo "<p>This user have already purchased one of this products</p>";
else
echo "<p>This user have not yet purchased one of this products</p>";
示例5 (定义用户ID
)-检测所定义的用户是否已经购物$user_id
现在,如果用户ID等于0并且当前用户未登录,则此函数将返回
。false
(如果未为访客用户定义帐单电子邮件)
请参见功能用法在这种情况下,也可以使用内置的woocommerce功能
if( has_bought_items() ) echo '<p>You have already made a purchase</p>'; else echo '<p>Welcome, for your first purchase you will get a discount of 10%</p>';
。// Define the user ID $user_id = 85; if( has_bought_items( $user_id ) ) echo '<p>customer have already made a purchase</p>'; else echo '<p>Customer with 0 purshases</p>';
。
这不会进行任何woocommerce模板修改,而仅使用过滤器false
检查客户是否已经带来了当前产品ID,在2.6 +版本中,woocommerce实现了功能wc_customer_bought_product
以检查客户是否已经带来了产品,我以前从未使用过它,但是基于您的文档可以创建一个如下所示的函数来检查产品ID的数组(如果其中一个已经被带入);
以下是我用来检查客户是否已经带入特定产品ID的先前方法,因此尽管我创建的功能不是ID数组,您仍可以使用这些功能中的任何一个>
woocommerce_is_purchasable
现在,我们可以检查产品ID是否已带,我们可以简单地在wc_customer_bought_product
上添加一个过滤器以创建我们自己的条件,下面的此函数只是您要实现的目标的简单示例,
仅更改了function cmk_check_product_brought( $ids=array() ) { if ( ! $ids ) return false; foreach ( $ids as $product => $id ) { if ( wc_customer_bought_product( wp_get_current_user()->user_email, get_current_user_id(), $id ) ) { return true; } } }
和function cmk_product_ordered( $id ) { // Get All order of current user $orders = get_posts( array( 'numberposts' => -1, 'meta_key' => '_customer_user', 'meta_value' => get_current_user_id(), 'post_type' => wc_get_order_types( 'view-orders' ), 'post_status' => array_keys( wc_get_order_statuses() ) ) ); if ( !$orders ) return false; // return if no order found $all_ordered_product = array(); // store all products ordered by ID in an array foreach ( $orders as $order => $data ) { // Loop through each order $order_data = new WC_Order( $data->ID ); // create new object for each order foreach ( $order_data->get_items() as $key => $item ) { // loop through each order item // store in array with product ID as key and order date a value $all_ordered_product[ $item['product_id'] ] = $data->post_date; } } // check if defined ID is found in array if ( isset( $all_ordered_product[ $id ] ) ) return true; else return false; }
值。
woocommerce_is_purchasable
并且应该将产品设置为不可购买(添加到购物车按钮将自动隐藏)。现在,如果您要为非购买产品添加消息,则可以简单地使用$required_purchased
的相同条件,添加消息并将其简单地挂在$conditional_purchase
或要显示的任何位置。
