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

這邊介紹 waifu2x線上版本，他是採用開源的 Video2x waifu2x 的技術，AI則是用深度卷積神經網絡(Deep Convolutional Neural Networks)，目前版本的限制是可以處理5MB，1500×1500 px的圖片，放大到2倍，類型可以選擇插畫(卡通)、照片如果不夠用可以自行去GitHUB，下載 waifu2x 並且在 Local 執行。

之前有介紹過免費智能還原放大圖像工具 – AI Image Upscaler Tool，和這套都算是真正免費的，市面上大約有20-30多個平台可以做AI圖像放大，但真正免費的超少，這邊介紹BigJPG，他是採用開源的 Video2x waifu2x 的技術，AI則是用深度卷積神經網絡(Deep Convolutional Neural Networks)，目前免費版本的限制是可以處理10MB，3000×3000 px的圖片，放大到4倍，如果不夠用可以自行去GitHUB，下載 waifu2x 並且在 Local 執行，不過免費的最大的缺點就是慢，所以有能力的還是歡迎大家支持。

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 );

常常對 wordpress 又愛又恨，這麼多年了，還是會把絕對路徑寫在資料庫中，每次要交付網站給客戶的時候，總是會遇到變更網址的需求，並且目前沒有很好的方法可以快速地修正，這邊先記錄如何透過資料庫管理程式 phpmyadmin 去修正所有在資料庫中的網址。

1.進入DB管理程式，搜尋舊的網址

這個步驟可以找出所有在DB中擁有舊網址的資料表，當然你可以自己一個一個資料表的點開來改，但好方法還是下 SQL CMD 去快速且大量的修正

2. SQL CMD 大量修改網址

原則上有三個表一定會需要修正， wp_options, wp_postmeta, wp_posts ，其他的資料表，就需要依靠第一步驟搜尋舊網址，找出尚未修正的資料表，然後再回來撰寫 SQL CMD

UPDATE wp_options SET option_value = REPLACE(option_value, 'old', 'new') WHERE option_name = 'home' OR option_name = 'siteurl';

UPDATE wp_postmeta SET meta_value = REPLACE(meta_value, 'old', 'new');

UPDATE wp_posts SET post_content = REPLACE(post_content, 'old', 'new');

UPDATE wp_posts SET guid = REPLACE(guid, 'old', 'new');
