網站程式設計-PHP
一、function.php
- 建立資料夾
#####################################################################################
# 建立目錄
#####################################################################################
if (!function_exists("mk_dir")) {
function mk_dir($dir = "") {
#若無目錄名稱秀出警告訊息
if (empty($dir)) {
return;
}
#若目錄不存在的話建立目錄
if (!is_dir($dir)) {
umask(000);
//若建立失敗秀出警告訊息
mkdir($dir, 0777);
}
}
}
二、SEO必要事項
- meta標籤
<html lang="zh" prefix="og: http://ogp.me/ns#">
<meta name="keywords" content="關鍵字">
<meta name="description" content="網頁描述" />
<meta name="author" content="作者名稱">
<meta name="copyright" content="版權所有人名稱">
<meta property="og:title" content="網站名稱或標題" />
<meta property="og:type" content="website" />
<meta property="og:url" content="網址" />
<meta property="og:image" content="要顯示的縮圖" />
<meta property="og:description" content="網頁描述" >
- 清 og暫存
https://developers.facebook.com/tools/debug/ - 網站標題
<title>商品 類別 網站標題</title>
- 使用「Search Console」
https://www.google.com/webmasters/tools/home?hl=zh-tw&pli=1
二、update.php
- 程式碼
- update.php只有執行，並沒畫面，所以不用樣板，
請問如何在後台製作一個按鈕來執行？
三、系統變數
- 自動新增
op_list() //-------- 系統變數 ----- go_update(); //-------- 系統變數 end-- - 函數

# 將預設系統項目寫入資料庫.
# formtype
# textbox => 單行
# textarea => 多行
# file => 檔案 => valuetype
# single_img =>單圖
# multiple_img => 多圖
