《PHP應用：PHP+jQuery 注冊模塊的改進（三）：更新到Smarty3.1》要點：
本文介紹了PHP應用：PHP+jQuery 注冊模塊的改進（三）：更新到Smarty3.1，希望對您有用。如果有疑問，可以聯系我們。
PHP學習Smarty3.1X( 最新版本 3.1.19) 比起Smarty2.x修改了不少特性.我把這個模塊使用Smarty3.1.18 ( 下載地址http://www.smarty.net/files/Smarty-3.1.18.zip )重新修改了一遍,是項目文件和目錄看起來更干凈更有療養.
PHP學習把Smarty壓縮包中的libs文件夾拷貝至模塊根目錄下,然后根目錄創立init.inc.php：
PHP學習/* *********************Smarty設置*********************** */
//根目錄路徑方式,用于Smarty設置
define("ROOT",str_replace("\\","/",dirname(__FILE__))."/");
PHP進修require ROOT.'libs/Smarty.class.php';
$smarty = new Smarty();
PHP進修//Smarty3設置默認路徑
$smarty ->setTemplateDir(ROOT.'templates/')
??????? ->setCompileDir(ROOT.'templates_c/')
??????? ->setPluginsDir(ROOT.'plugins/')
??????? ->setCacheDir(ROOT.'cache/')
??????? ->setConfigDir(ROOT.'configs');
PHP學習$smarty->caching = false;
$smarty->cache_lifetime = 60*60*24; //模版緩存有效光陰為1天
$smarty->left_delimiter = '<{';
$smarty->right_delimiter = '}>';
PHP進修/***********************************************************/
PHP學習//根目次url方式
$PHP_SELF=$_SERVER['PHP_SELF'];
$ROOT_URL='http://'.$_SERVER['HTTP_HOST'].substr($PHP_SELF,0,strrpos($PHP_SELF,'/')+1);
define(ROOT_URL,$ROOT_URL);
PHP學習//模版目次url方式
define("Template_Dir",$ROOT_URL.'templates');
PHP學習創建初始化文件中呈現的templates,templates_c,plugins,cache,configs文件夾.
PHP學習修改的文件都比擬相似,而且也非常easy,這里列出register.html和register.php文件的修改.
PHP進修register.html是注冊的前臺頁面,路徑是/templates/register.html
PHP學習<script src="<{$Template_Dir}>/js/jquery-1.8.3.min.js"></script>
<script src="<{$Template_Dir}>/js/register.js"></script>
<!--郵箱下拉-->
<script src="<{$Template_Dir}>/js/emailup.js"></script>
</head>
PHP進修<body>
<{*導入header.html*}>
<{include file="header.html"}>
PHP進修<!-- 內容區 -->
<div id="container">
PHP進修??? <!--注冊區-->
??? <div id="register">
PHP學習??????? <!-- 注冊表單 -->
??????? <form id="register-form" action="register_chk.php" method="post">
???????????
??????????? <!-- 用戶名 -->???????
??????????? <!-- placeholder HTML5的屬性,提供提示信息.輸入字段為空時顯示,并會在字段獲得焦點時消失 -->
??????????? <div class="ipt fipt">
??????????????? <input type="text" name="uname" id="uname" value="" placeholder="輸入用戶名"? autocomplete="off" />
??????????????? <!--提示筆墨-->
??????????????? <span id="unamechk"></span>
??????????? </div>
PHP進修??????????? <!-- email -->???????????
??????????? <div class="ipt">
??????????????? <input type="text" name="uemail" id="uemail" value="" placeholder="常用郵箱地址" autocomplete="off" /><span id="uemailchk"></span><ul class="autoul"></ul>
??????????? </div>
PHP學習??????????? <!-- 暗碼 -->
??????????? <div class="ipt">
??????????????? <input type="password" name="upwd" id="upwd" value="" placeholder="設置暗碼" /><div class="upwdpic"><span id="upwdchk"></span><img id="pictie" /></div>

??????????? <div class="ipt">
??????????????? <input type="password" name="rupwd" id="rupwd" value="" placeholder="確認暗碼" /><span id="rupwdchk"></span>
??????????? </div>
PHP進修??????????? <!--驗證碼-->
??????????? <div class="ipt iptend">
??????????????? <input type='text' id='yzm' name='yzm' placeholder="驗證碼" autocomplete="off" />
??????????????? <img id='yzmpic' src='valcode.php?num=<{showval}>' style="cursor:pointer" alt="驗證碼" title="驗證碼">
??????????????? <a style="cursor:pointer" id='changea'>
??????????????????? <img id="refpic" src="<{$Template_Dir}>/images/ref.jpg" alt="刷新驗證碼">
??????????????? </a>
??????????????? <span id='yzmchk'></span>
??????????? </div>
PHP學習??????????? <!-- 提交 -->
??????????? <button type="button" id="sub">立刻注冊</button>
PHP學習??????????? <!-- 服務條款 -->
??????????? <span class="fuwu">
??????????????? <input type="checkbox" name="agree" id="agree" checked="checked">
??????????????? <label for="agree">我同意? <a href="#">" 服務條款? "</a> 和? <a href="#">" 網絡游戲用戶隱私權掩護和個人信息利用政策 "</a>
??????????????? </label>
??????????? </span>
PHP進修??????? </form>
PHP進修??? </div>
PHP進修</div>
</body>
</html>
PHP進修register.php:
PHP進修session_start();
PHP進修require_once 'init.inc.php';
PHP學習//設置模版目次,用于模版頁頭部引用CSS、JS、Images
$smarty->assign("Template_Dir",Template_Dir);
PHP進修$smarty->display('register.html');
PHP學習同時擴充了天生驗證碼插件,路徑是/plugins/function.showval.php
PHP學習//天生驗證碼
function smarty_function_showval($params,$smarty){
PHP進修??? $num = "";
??? for($i=0;$i<4;$i++){
PHP進修??????? $tmp = rand(1,15);
??????? if ($tmp > 9) {
??????????? switch ($tmp) {
??????????????? case(10):
??????????????????? $num .= 'a';
??????????????????? break;
??????????????? case(11):
??????????????????? $num .= 'b';
??????????????????? break;
??????????????? case(12):
??????????????????? $num .= 'c';
??????????????????? break;
??????????????? case(13):
??????????????????? $num .= 'd';
??????????????????? break;
??????????????? case(14):
??????????????????? $num .= 'e';
??????????????????? break;
??????????????? case(15):
??????????????????? $num .= 'f';
??????????????????? break;
??????????? }
??????? } else {
??????????? $num .= $tmp;
??????? }???
??? }
PHP進修??? $mdnum = md5($num);
??? $_SESSION['num'] = $num;
??? $_SESSION['mdnum'] = $mdnum;
PHP進修??? //寫在session之后
??? return $mdnum;
}
PHP進修$_SESSION['num'] = smarty_function_showval($params,$smarty);
$_SESSION['mdnum'] = md5(smarty_function_showval($params,$smarty));
PHP學習注意插件的定名：
PHP學習文件名要放在根目錄的plugins目錄下,命名規則是 function.函數名.php,文件中函數的命名規則是 smarty_function_函數名($params,$smarty),此中第一個參數是傳遞給模板的關聯數組,第二個參數是接收自動傳入的smarty對象,函數要有返回值.
