修改管理者密碼

這篇我們介紹管理員密碼是如何修改的,展示頁面我們已經看到了,修改,連結到pass.html頁面

這個就是修改的頁面

        <div>
          <input type="password" class="input w50" name="renewpass" size="50" placeholder="请再次输入新密码" data-validate="required:请再次输入新密码,repeat#newpass:两次输入的密码不一致" />

          <label></label>
        </div>
        <div>
          <button class="button bg-main icon-check-square-o" type="submit"> 提交</button>   
        </div>
      </div>      
    </form>
  </div>
</div>
</body></html>

連結到pass.html頁面之後,建立一pass.php的檔案

輸入的原始密碼和資料庫中的密碼進行判斷比較,如何符合,則往下判斷,用update去修改原密碼

程式碼如下:

<?php 
    require_once("../config/config.php");
    mysql_query("set names = utf8");
      $sql = "SELECT * FROM admin"; 
      // if($_GET){
      //   $id = $_GET['id'];
      //   $sql0 = 'select username from user where id ='.$id;
      //   $result =mysql_query($sql0);
      //   $username = mysql_fetch_assoc($result)['username'];
      // }
      if($_POST){
        $oldpassword = $_POST ["mpass"]; 
        $newpassword = $_POST ["newpass"]; 
        $confirm = $_POST['renewpass'];
        $sql1 = 'select password from admin where id=1 ';
        $result1 = mysql_query($sql1);
        $password = mysql_fetch_assoc($result1)['password'];
        if ($oldpassword !== $password) {
          echo "与原密码不符";
        }
          else{
          if ($newpassword==$confirm) {
              $sql2 = 'UPDATE admin SET `password`="'.$newpassword.'" where id =1';
              mysql_query ($sql2);
              header('location:./usermessage.php');
          }
        }
        }
        ?>

寫完之後,執行一下

如圖,發現資料庫的密碼已經修改成功

這樣,我們就完成了修改管理員密碼的功能。
