網頁前端設計與開發運用培訓班
==============

一、head.php

```
<pre class="brush:as3;">
<?php
/*
1. head.php為前台每個程式都會引入的檔案
2. 所有檔案都必須執行的流程，請放到這裡
3. smarty_01
 */
session_start(); //啟用 $_SESSION,前面不可以有輸出
error_reporting(E_ALL);@ini_set('display_errors', true); //設定所有錯誤都顯示
$http = 'http://';
if (!empty($_SERVER['HTTPS'])) {
	$http = ($_SERVER['HTTPS'] == 'on') ? 'https://' : 'http://';
}

#網站實體路徑(不含 /)
define('_WEB_PATH', str_replace("\\", "/", dirname(__FILE__)));

#網站URL(不含 /)
define('_WEB_URL', $http . $_SERVER["HTTP_HOST"] . str_replace($_SERVER["DOCUMENT_ROOT"], "", _WEB_PATH));

#--------- WEB -----
#程式檔名(含副檔名)
$WEB['file_name'] = basename($_SERVER['PHP_SELF']); //index.php
//basename(__FILE__)head.php
#--------- WEB END -----

#
/*---- 必須引入----*/
#引入樣板引擎
require_once _WEB_PATH.'/smarty.php';
#引入資料庫設定
require_once _WEB_PATH.'/sqlConfig.php';
#引入設定檔
require_once _WEB_PATH . '/function.php';
```

二、sqlConfig.php

```
<pre class="brush:as3;">
<?php
#資料庫伺服器
$db_host = "localhost";
#資料庫使用者帳號
$db_user = "root";
#資料庫使用者密碼
$db_password = "111111";
#資料庫名稱
$db_name = "web"; 
#PHP 5.2.9以後
$db = new mysqli($db_host, $db_user, $db_password, $db_name); 
if ($db->connect_error) {
  die('無法連上資料庫 (' . $db->connect_errno . ') '
        . $db->connect_error);
} 
#設定資料庫語系
$db->set_charset("utf8");
```

三、smarty.php

```
<pre class="brush:as3;">
<?php
#引入smarty物件
require_once _WEB_PATH . '/class/smarty/libs/Smarty.class.php';
#實體化
$smarty = new Smarty;
#指定左標籤定義符
$smarty->left_delimiter = "<{"; //指定左標籤
#指定左標籤定義符
$smarty->right_delimiter = "}>"; //指定右標籤
#指定模版存放目錄
$smarty->template_dir = _WEB_PATH . '/templates/';
#指定編譯文件存放目錄
$smarty->compile_dir = _WEB_PATH . '/templates_c/';
#指定配置文件存放目錄
$smarty->config_dir = _WEB_PATH . '/configs/';
#暫存路徑
$smarty->cache_dir = _WEB_PATH . '/cache/';

#開啟調試控制台，輸出變數
//$smarty->debugging = true;
#開啟緩存
//$smarty->caching = true;
#設定緩存時間，詳見 https://www.smarty.net/docs/zh_CN/caching.tpl
//$smarty->cache_lifetime = 120;

#定義模板URL 
$smarty->assign("xoImgUrl", _WEB_URL . '/templates/'); 
$smarty->assign("xoAppUrl", _WEB_URL."/"); 
```

四、function.php

```
<pre class="brush:as3;">
<?php
/**
 * Get variables passed by GET or POST method
 *
 * Comment by Taiwen Jiang (a.k.a. phppp): THE METHOD IS NOT COMPLETE AND NOT SAFE. YOU ARE ENCOURAGED TO USE PHP'S NATIVE FILTER_VAR OR FILTER_INPUT FUNCTIONS DIRECTLY BEFORE WE MIGRATE TO XOOPS 3.
 */
function system_CleanVars(&$global, $key, $default = '', $type = 'int')
{
  switch ($type) {
    case 'array':
      $ret = (isset($global[$key]) && is_array($global[$key])) ? $global[$key] : $default;
      break;
    case 'date':
      $ret = (isset($global[$key])) ? strtotime($global[$key]) : $default;
      break;
    case 'string':
      $ret = (isset($global[$key])) ? filter_var($global[$key], FILTER_SANITIZE_MAGIC_QUOTES) : $default;
      break;
    case 'int': default:
      $ret = (isset($global[$key])) ? filter_var($global[$key], FILTER_SANITIZE_NUMBER_INT) : $default;
      break;
  }
  if ($ret === false) {
    return $default;
  }
  return $ret;
}

###############################################################################
#  轉向函數
###############################################################################
function redirect_header($url = "", $time = 3000, $message = '已轉向！！') {
  $_SESSION['redirect'] = "\$.jGrowl('{$message}', {  life:{$time} , position: 'center', speed: 'slow' });";
  header("location:{$url}");
  exit;
}
###############################################################################
#  取得目前網址

if (!function_exists("getCurrentUrl")) {
  function getCurrentUrl() {
    global $_SERVER;
    $protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']), 'https') === FALSE ? 'http' : 'https';
    $host = $_SERVER['HTTP_HOST'];
    $script = $_SERVER['SCRIPT_NAME'];
    $params = $_SERVER['QUERY_STRING'] ? '?' . $_SERVER['QUERY_STRING'] : "";
 
    $currentUrl = $protocol . '://' . $host . $script . $params;
    return $currentUrl;
  }
}
 
###############################################################################
#  獲得填報者ip
###############################################################################
if (!function_exists("getVisitorsAddr")) {
  function getVisitorsAddr() {
    if (!empty($_SERVER["HTTP_CLIENT_IP"])) {
      $ip = $_SERVER["HTTP_CLIENT_IP"];
    } elseif (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) {
      $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
    } else {
      $ip = $_SERVER["REMOTE_ADDR"];
    }
    return $ip;
  }
}

#####################################################################################
#  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);
    }
  }
}

```

五、index.php

```
<pre class="brush:as3;">
<?php
/* 引入檔頭，每支程都會引入 */
require_once 'head.php';

/* 過濾變數，設定預設值 */
$op = system_CleanVars($_REQUEST, 'op', '', 'string');
$sn = system_CleanVars($_REQUEST, 'sn', '', 'int');

/* 程式流程 */
switch ($op){
	case "xxx" :
		$msg = xxx();
		header("location:index.php");//注意前面不可以有輸出
		exit;

case "yyy" :
		$msg = yyy();
		header("location:index.php");//注意前面不可以有輸出
		exit;

default:
		$op = "op_list";
		op_list();
		break;	
}

/*---- 將變數送至樣版----*/
$smarty->assign("WEB", $WEB);
$smarty->assign("op", $op);

/*---- 程式結尾-----*/
$smarty->display('theme.tpl');

/*---- 函數區-----*/
function xxx(){
	global $smarty;

}
function yyy(){
	global $smarty;
}

function op_list(){
	global $smarty;
}

```

user.php

```
<pre class="brush:as3;">
<?php
/* 引入檔頭，每支程都會引入 */
require_once 'head.php';
 
/* 過濾變數，設定預設值 */
$op = system_CleanVars($_REQUEST, 'op', 'op_form', 'string');
$sn = system_CleanVars($_REQUEST, 'sn', '', 'int');
// echo $op;die();
 
/* 程式流程 */
switch ($op){
  case "op_form" :
    $msg = op_form();
    break;
 
  case "yyy" :
    $msg = yyy();
    header("location:index.php");//注意前面不可以有輸出
    exit;
 
  default:
    $op = "op_list";
    op_list();
    break;  
}
 
/*---- 將變數送至樣版----*/
$smarty->assign("WEB", $WEB);
$smarty->assign("op", $op);
 
/*---- 程式結尾-----*/
$smarty->display('user.tpl');
 
/*---- 函數區-----*/
function op_form(){
  global $smarty;
 
}
function yyy(){
  global $smarty;
}
 
function op_list(){
  global $smarty;
}
