在 WooCommerce 掛鈎中訪問客戶自定義用戶元數據

Question

這個問題與user_register 掛鈎

我需要在 woocommerce 的用戶注冊表單上添加一些額外的字段我使用了自定義用戶注冊字段 - WooCommerce 插件

我的問題是如何使用 add_action 鈎子訪問這些添加字段的值？

這是我到目前為止所做的，

add_action( 'user_register', 'new_contact', 10, 3 );

function new_contact( $user_id ) {

    if ( isset( $_POST['first_name'] ) )
        update_user_meta($user_id, 'first_name', $_POST['first_name']);
    $customer = new WC_Customer( $user_id );
    echo $customer;
    
    wp_die();
    

}

以下是回顯的output：

{
"id":12,
"date_created":{"date":"2020-07-27 16:58:52.000000","timezone_type":1,"timezone":"+00:00"},
"date_modified":null,
"email":"c@hotmail.com",
"first_name":""
,"last_name":"",
"display_name":"c",
"role":"customer",
"username":"c",
"billing":{"first_name":"","last_name":"","company":"","address_1":"","address_2":"","city":"","postcode":"","country":"","state":"","email":"","phone":""},
"shipping":{"first_name":"","last_name":"","company":"","address_1":"","address_2":"","city":"","postcode":"","country":"","state":""},
"is_paying_customer":false,
"meta_data":[
    {"id":516,"key":"afreg_additional_1564","value":"c"},
    {"id":517,"key":"afreg_additional_1565","value":"c"},
    {"id":518,"key":"afreg_additional_1566","value":"c"},
    {"id":519,"key":"afreg_additional_1555","value":"c"},
    {"id":520,"key":"afreg_additional_1556","value":"c"},
    {"id":521,"key":"afreg_additional_1557","value":"c"},
    {"id":522,"key":"afreg_additional_1558","value":"California"},
    {"id":523,"key":"afreg_additional_1559","value":"c"},
    {"id":524,"key":"afreg_additional_1560","value":"6181001010"},
    {"id":525,"key":"afreg_additional_1561","value":"c"},
    {"id":526,"key":"_yoast_wpseo_profile_updated","value":"1595894332"}
    ]
}

我可以看到我添加的自定義字段存儲在“meta_data”中

我如何將每個值存儲在變量中？

Answer 1

您可以使用WC_Data上的WC_Customer方法訪問此meta data ，例如：

• get_meta_data()獲取一個未受保護的WC_Meta_Data對象數組
• get_meta($meta_key)從特定的元鍵中獲取值

要從WC_Meta_Data object 訪問數據，您將使用get_data()方法。

所以這是代碼的工作示例：

$user_id  = 12; // For user ID 12

// Get an instance of the WC_Customer Object from user Id
$customer = new WC_Customer( $user_id );

// Get the meta value from a specific meta key
$meta_value = $customer->get_meta('afreg_additional_1558');
echo 'Value: ' . $meta_value . '<br>'; //Display the value

// Get an unprotected array of `WC_Meta_Data` objects
$user_meta_data = $customer->get_meta_data();

// Loop through `WC_Meta_Data` objects
foreach( $customer->get_meta_data() as $meta_data ){
    // get an unprotected array of the current WC_Meta_Data object data
    $meta_data_array = $meta_data->get_data();
    
    $meta_key   = $meta_data_array['key']; // The meta key
    $meta_value = $meta_data_array['value']; // The meta value
    $meta_value = is_array($meta_value) ? implode(' | ', $meta_value) : $meta_value;
    
    // Testing output
    echo $meta_key  . ': ' . $meta_value . '<br>';
}

所以在你的 function 中：

add_action( 'user_register', 'new_contact', 10, 3 );
function new_contact( $user_id ) {

    if ( isset( $_POST['first_name'] ) )
        update_user_meta($user_id, 'first_name', $_POST['first_name']);

    // Get an instance of the WC_Customer Object from user Id
    $customer = new WC_Customer( $user_id );
    
    // Get the meta value from a specific meta key
    $meta_value = $customer->get_meta('afreg_additional_1558');
    echo 'Value: ' . $meta_value . '<br>'; //Display the value
    
    // Get an unprotected array of `WC_Meta_Data` objects
    $user_meta_data = $customer->get_meta_data();
    
    // Loop through `WC_Meta_Data` objects
    foreach( $customer->get_meta_data() as $meta_data ){
        // get an unprotected array of the current WC_Meta_Data object data
        $meta_data_array = $meta_data->get_data();
        
        $meta_key   = $meta_data_array['key']; // The meta key
        $meta_value = $meta_data_array['value']; // The meta value
        $meta_value = is_array($meta_value) ? implode(' | ', $meta_value) : $meta_value;
        
        // Testing output
        echo $meta_key  . ': ' . $meta_value . '<br>';
    }
   
    // echo $customer;
    
    wp_die();
}

或者您可以使用 Wordpress 方式使用get_user_meta() function來獲取所有用戶元數據的數組：

add_action( 'user_register', 'new_contact', 10, 3 );
function new_contact( $user_id ) {

    if ( isset( $_POST['first_name'] ) )
        update_user_meta($user_id, 'first_name', $_POST['first_name']);

    // Get an instance of the WP_User Object from user Id
    $user = new WP_User( $user_id );
    
    // Get the meta value from a specific meta key
    $meta_value = $user->afreg_additional_1558;
    echo 'Value: ' . $meta_value . '<br>'; //Display the value

    // OR using 
    $meta_value = get_user_meta( $user_id, 'afreg_additional_1560', true );
    echo 'Value: ' . $meta_value . '<br>'; //Display the value
    
    // Get an array of all user meta data
    $user_meta_data = get_user_meta( $user_id );
    
    // Testing output meta data
    print_r( $user_meta_data );
    
    wp_die();
}

要為您的相關用戶元數據獲取正確的元鍵，您還可以查看wp_usermeta數據庫表。

最后，正如您現在所看到的，將每個值存儲在變量中很容易，但是您的第三方插件並沒有使事情變得簡單和明確，因為每個 meta_key 都是一種內部 id。
