WordPress-取得User Id的方法

by | 7 月 10, 2022 | PHP, wordpress

我們可以用 php 程式，來取得使用者的資訊，最重要的當然是 User ID 的取得，能取得 User ID 才能進行使用者的資訊取得，取得uid的方法百百種，這邊列出四種常用的場景，取得當下登入的使用者ID，另用會員的關鍵資料取得會員ID，利用文章取得作者ID，在商店中取得客戶ID，

1.get_current_user_id()

$current_user_id = get_current_user_id();
$current_user = wp_get_current_user();
$current_user_id = $current_user->ID;

2.使用會員資訊取得ID，get_user_by()

利用Email取的ID

$the_user = get_user_by('email', '[email protected]');
$the_user_id = $the_user->ID;

利用登入帳號

$the_user = get_user_by('login', 'rain');
$the_user_id = $the_user->ID;

3.利用文章資訊取得作者 ID

$my_post = get_post( $id ); // $id - Post ID
echo $my_post->post_author; // print post author ID

4.在woocommerce中取得訂單的客戶ID

$order = wc_get_order( 123 ); // your order ID
$customer_id = $order->get_customer_id(); // or $order->get_user_id() – the same

在電商的世界內，UTM是一個通用技巧，用來知道是透過那種管道進來的資訊，這些資訊可以用在廣告活動中，蒐集以及統計好UTM資訊，就可以知道要針對那一個管道(google or FB or YT or IG)要去多加強，加大廣告力度，或是修正內文，並且反覆修正、測試、驗證，這樣才可以達到最大效益。

1.Divi Insert Module form

2.建立欄位ID

3.將utm欄位隱藏起來

4.依序把UTM需要的欄位都建立好，下面畫面中的utm_開頭的都可以自建

WordPress 存取 user meta 的方法

by | 7 月 9, 2022 | PHP, wordpress

在 WordPress 中，尤其是使用到 woocommerce 商店功能時候，最常需要客製化的通常是使用者的各式各樣資訊，例如有使用者的手機號碼、推薦人資訊等，通常這些資訊沒有良好的plugin可以支援，欄位高度客製化，這時可以寫點 php 程式，來支持讓自己的網站更美好，以下分CRUD新增、修改、刪除、讀取來做說明。

新增 user meta 的方法

add_user_meta(int $user_id, string $meta_key,  mixed $meta_value,  bool $unique = false);

刪除 user meta 的方法

delete_user_meta( $user_id, $meta_key, $meta_value );

修改 user meta 的方法

update_user_meta ( $user_id, $meta_key, $meta_value, $prev_value );

讀取 user meta 的方法

get_user_meta( $user_id, $meta_key, $single );

如果要做一個商業網站，通常需要自行控制 WordPress 的前端顯示，最常見的應用則是把前台網站上的 admin bar 關閉，提供一個更專業且乾淨的前端，這邊介紹幾種關閉和打開 admin bar 的方法

方法一、使用程式碼低階控制

將下列程式碼擇一加入佈景主題的functions.php

add_filter('show_admin_bar','hide_admin_bar');
function hide_admin_bar($flag){
  	return false;
}

針對特定使用者隱藏

function my_function_admin_bar($content) {
    return ( current_user_can("administrator") ) ? $content : false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');

方法二、針對使用者移除工具欄

到後台的使用者->個人資料中，選擇是否檢視網站前端時顯示工具列

方法三、採用 Admin Bar Disabler Plugins

下載 Admin Bar Disabler 利用外掛來控制是否要開啟 admin bar

方法四、WP MiniBar

用WP MiniBar，可以在想隱藏的時候就隱藏，想要出現的時候就讓他出現，只要簡單選一下就可以了

woocommerce 在 wordpress 中是可以擁有自己的除錯系統的，可以獨立在 wordpress, php, nginx 以外，可以利用 WooCommerce 官方提供的 Log 記錄功能，可以記錄各種狀態，和自己的標籤，可以比較有秩序且快速的除錯

使用 WC_Logger

WC_Logger官方文件示範了標準用法

$log = new WC_Logger();
$log_entry = print_r( $e, true );
$log_entry .= 'Exception Trace: ' . print_r( $e->getTraceAsString(), true );
$log->log( 'new-woocommerce-log-name', $log_entry );

簡易用法

$logger = wc_get_logger();
$logger->debug( 'debug message', array( 'source' => 'my-extension' ) );

查看 WC Log

在 WP 後台，選擇 WooCommerce -> 狀態

並且選擇 狀態 -> 日誌紀錄 ，選擇完畢後，在選擇你建立的紀錄標籤後，就可以看到清楚的訊息輸出了

同廠加映，用WordPress內建的除錯

編輯 wp-config，將 WP_DEBUG 的選項打開，缺點就是訊息太多，比較不好看清楚

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
