Php 允许用户在Woocommerce中只购买一次特定产品

以下代码用于Woocommerce，允许在购买后再次购买

function sv_disable_repeat_purchase( $purchasable, $product ) {
    // Enter the ID of the product that shouldn't be purchased again
    $non_purchasable = 40021;

    // Get the ID for the current product (passed in)
    $product_id = $product->is_type( 'variation' ) ? $product->variation_id : $product->id;

    // Bail unless the ID is equal to our desired non-purchasable product
    if ( $non_purchasable != $product_id ) {
        return $purchasable;
    }

    // return false if the customer has bought the product
    if ( wc_customer_bought_product( wp_get_current_user()->user_email, get_current_user_id(), $product_id ) ) {
        $purchasable = false;
    }

    // Double-check for variations: if parent is not purchasable, then variation is not
    if ( $purchasable && $product->is_type( 'variation' ) ) {
        $purchasable = $product->parent->is_purchasable();
    }

    return $purchasable;
}
add_filter( 'woocommerce_variation_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );
add_filter( 'woocommerce_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );

请给我一个帮助，将$non_purchable=40021更改为产品数组

这是您的代码和数组。请检查它是否符合您的要求：

function sv_disable_repeat_purchase( $purchasable, $product ) {

    // Enter the ID of the product that shouldn't be purchased again
    $non_purchasable_arr = array(
        40021,
        40022
    );

    // Get the ID for the current product (passed in)
    $product_id = $product->is_type( 'variation' ) ? $product->variation_id : $product->id;

    // Bail unless the ID is equal to our desired non-purchasable product
    foreach ( $non_purchasable_arr as $non_purchasable ) {
        if ( $non_purchasable !== $product_id ) {
            return $purchasable;
        }
    }

    // return false if the customer has bought the product
    if ( wc_customer_bought_product( wp_get_current_user()->user_email, get_current_user_id(), $product_id ) ) {
        $purchasable = false;
    }

    // Double-check for variations: if parent is not purchasable, then variation is not
    if ( $purchasable && $product->is_type( 'variation' ) ) {
        $purchasable = $product->parent->is_purchasable();
    }

    return $purchasable;
}

add_filter( 'woocommerce_variation_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );
add_filter( 'woocommerce_is_purchasable', 'sv_disable_repeat_purchase', 10, 2 );

更新（删除了过时的、不需要的

$product->variation\u id

…）

您只需在_array（）中使用PHP条件函数

。此外，您的代码已经过时：


这是过时的
$product->variation\u id
将
$product->id
替换为
$product->get_id（）

下面是一个简化的重新访问代码版本：

add_filter( 'woocommerce_variation_is_purchasable', 'products_purchasable_once', 10, 2 );
add_filter( 'woocommerce_is_purchasable', 'products_purchasable_once', 10, 2 );
function products_purchasable_once( $purchasable, $product ) {
    // Here set the product IDs in the array that can be purchased only once 
    $targeted_products = array(40021, 40038, 40171);

    // Only for logged in users and not for variable products
    if( ! is_user_logged_in() || $product->is_type('variable') )
        return $purchasable; // Exit

    $user = wp_get_current_user(); // The WP_User Object

    if ( in_array( $product->get_id(), $targeted_products ) &&
    wc_customer_bought_product( $user->user_email, $user->ID, $product->get_id() ) ) {
        $purchasable = false;
    }

    return $purchasable;
}

代码位于活动子主题（或活动主题）的function.php文件中。测试和工作
