php實作忘記密碼找回功能的方法:1、使用者註冊時需提供一個E-MAIL信箱;2、開啟表單並輸入註冊用的E-MAIL信箱;3、從資料庫查找到該用戶訊息,並更新該用戶的密碼為一個臨時密碼;4、借助Jmail功能實現修改密碼即可。
本教學操作環境:windows10系統、php5.6,本文適用於所有品牌的電腦。

PHP會員找回密碼功能的簡單實作
##設定想法1、用戶註冊時需要提供一個E-MAIL郵箱,目的就是用該郵箱找回密碼。 2、當使用者忘記密碼或使用者名稱時,點擊登入頁面的「找回密碼」超鏈接,打開表單,並輸入註冊用的E-MAIL郵箱,提交。 3、系統透過該郵箱,從資料庫中查找到該使用者信息,並更新該使用者的密碼為一個臨時密碼(例如:12345678)。 4、系統藉助Jmail功能把該使用者的資料傳送到該使用者的信箱(內容包括:使用者名稱、臨時密碼、提醒使用者及時修改臨時密碼的提示語)。 5、使用者用臨時密碼即可登入。 HTML我們在找回密碼的頁面上放置一個要求使用者輸入註冊時所使用的郵箱,然後提交前台js來處理互動。 程式碼如下<p><strong>輸入您註冊的電子郵箱,找回密碼:</strong></p> <p><input type="text" class="input" name="email" id="email"><span id="chkmsg"></span></p> <p><input type="button" class="btn" id="sub_btn" value="http://www.bitscn.com/pdb/php/201609/提 交"></p>
$(function(){ $("#sub_btn").click(function(){ var email = $("#email").val(); var preg = /^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*/; //匹配Email if(email=='' || !preg.test(email)){ $("#chkmsg").html("請填寫正確的郵箱!"); }else{ $("#sub_btn").attr("disabled","disabled").val('提交中..').css("cursor","default"); $.post("sendmail.php",{mail:email},function(msg){ if(msg=="noreg"){ $("#chkmsg").html("該郵箱尚未註冊!"); $("#sub_btn").removeAttr("disabled").val('提 交').css("cursor","pointer"); }else{ $(".demo").html("<h3>"+msg+"</h3>"); } }); } }); })
