原來的版本是將插圖寫在外掛的php檔案中

如果要修改的話，可以透過兩種方式

第一種是直接修改php檔案後，再重新上傳外掛程式

另一種是直接在外掛編輯器裡修改

但是這兩種方式都是直接動到全部程式

所以想說能不能從外掛設定頁面中改需要修改的部分就好

外掛的設定頁面參考了《WordPress站長練功秘笈：網站客製化、佈景主題與外掛開發的16堂課》中的範例

但由於我想要修改的設定會有兩個參數：stickerPackageId跟stickerId

如果只想在wp_option增加一個紀錄，那麼外掛程式的參數都必須用陣列的方式儲存到資料庫

整體外掛程式可以分成A:主要功能、B：外掛頁面的設定

A的部分就是套用前一版的兩種add_action

程式碼在#23~#103

而B是這次練習的核心部分

可以再分成

B1-設定頁面內容，程式碼在#105~#163

#105~#110：透過add_action的admin_enqueue_scripts鈎掛trico_line_load_bootstrap，來引用外部bootstrap的CSS、JavaScript

#110~#163 ：trico_line_mainpage是外掛設定頁面的內容

B2-wp資料庫處理

B2-1 #9~#21：設定外掛功能選項在wp_options的初始值；以及在其他函式都會用到的全域變數

B2-2 #164~#177：透過add_action的admin_menu鈎掛外掛設定選單-trico_line_setting_menu，呼叫外掛設定頁面的函式-trico_line_mainpage，再透過add_action的admin_init鈎掛外掛初始設定-trico_line_register_settings

B2-3 #178~#186：trico_line_sanitize_options-變數預處理，這個則是鈎掛於外掛初始設定-trico_line_register_settings

B2-4 #188~#193：trico_line_register_settings-外掛初始設定，在外掛設定選單-trico_line_setting_menu中被呼叫

可以發現每個函式都是相互鈎掛與呼叫，而其中trico_line_register_settings-外掛初始設定register_setting的變數群組，又必須跟表單內的settings_fields的變數群組一致
