外掛說明
Black Bar 是專為 WordPress 開發者設計的 Debug Bar 外掛的擴充功能，它會收集並顯示錯誤訊息、已執行的 SQL 查詢、造成網站遲緩的動作及勾點、佈景主題範本、全域變數並提供分析工具。
這個外掛協助開發者開發的方式：
- 使用主控台對程式碼進行偵錯
- 檢查 COOKIE、GET、POST、SERVER、SESSION、WP_Screen 等全域變數
- 使用分析工具測量程式碼效能
- 在主控台檢視載入頁面時發生的 PHP 錯誤
- 檢視包含執行時間及反向追蹤的已執行 MySQL 查詢
- 檢視目前使用的佈景主題依據載入順序的範本檔案
- 檢視依據優先順序的回呼的 50 個最慢動作及篩選器勾點
安裝方式
如果未曾安裝過 WordPress 外掛，請參考這份官方說明文件。
常見問題集
-
如何在主控台新增項目？
-
如需將項目新增至主控台，請在程式碼中的任何位置插入以下 PHP 程式碼：
do_action('console', 'Enter something to debug here');也可以如下所示般加入選用記錄層級：
do_action('console', 'Enter something to debug here', 'error');可用的記錄層級：
debug、info、notice、warning、error、critical、alert及emergency。 -
如何使用分析工具？
-
如需使用分析工具，請在要進行分析的程式碼的前方及後方插入對應的 PHP 程式碼：
程式碼前方：
do_action('timer:start', 'Enter a description of what you are profiling here');程式碼後方：
do_action('timer:stop'); -
如何為非網站管理員啟用這個外掛？
-
依照預設，僅有網站管理員可以使用 Black Bar；如需為全部登入使用者啟用這個外掛，請使用以下程式碼片段：
add_filter('blackbar/enabled', 'is_user_logged_in'); -
如何變更最慢的勾點顯示數量？
-
依照預設，Black Bar 會顯示 50 個最慢的動作/篩選器勾點；如需顯示全部勾點，請使用以下程式碼片段：
add_filter('blackbar/hooks/all', '__return_true');

Was wondering why my wordpress installation was unbearably slow. This plugin helped me discover the massive amount of SQL queries generated by 2 conflicting plugin settings. Problem solved!

Thank you for giving new life to BlackBox Debug Bar!
Not only the usefulness of this plugin, but the beautiful PHP coding leads me to write this review. I have learnt a lot from your code.

This is a beautiful way to interpress the data, I am a developer and this plugin helped me correct errors, I really feel very inspired. Thanks for the idea.
