登录注册案例一

这个项目只有登录，貌似是我接触的第一个有登录的项目，写的与想死的心都有了，全程看着别人敲。。。。。

 

又是熟悉的mask遮罩

<div id="mask" style="display: none;">
  <div id="artl">
    <div class="a-top">
      <h4>XX登录</h4>
      <div id="close"></div>
    </div>
    <form>
        <div class="form_control1">
          <label>手机号码：</label><input class="required1" type="text" name="phone" id="phone">
        </div>
        <div class="form_control1">
          <label>密      码：</label><input class="required1" type="password" name="password" id="password">
        </div>
          <input type="button" id="logins" value="登录" class="login">
      </form>
  </div>
</div>

JS弹出控制与表单验证

<script type="text/javascript">
  $(".checked-href").click(function(){
    $("#mask").fadeIn();
    $("#close").click(function(){
      $("#mask").fadeOut();
    })
  })
</script>
 <script>
$(function () {
  $("#logins").click(function(){
    var phone = $("#phone").val();
    var password = $("#password").val();
    if (phone=="") {
      alert("手机不能为空")
       $("#phone").focus();
      return
    }
    if(password==""){
      alert("密码不能为空")
      $("#password").focus();
      return
    }
    var myreg=/^1(3|5|7|8)\d\d\d\d\d\d\d\d\d$/;   
     if(!myreg.test(phone)){
      alert("手机格式不正确")
      $("#phone").focus();
      return
     }
    $.post("{PURL('checked/login')}",{ 'phone':phone,'password':password },function(data){
      if (data == 1) {
        window.location.href="{PURL('checked')}";
      }else{
        alert(data)
      }
    })
  })
})
 
 </script>

php登录验证部分的代码

public function login(){
        $phone = $_POST['phone'];
        $password = md5($_POST['password']);
        $user = $this->db->getOne("SELECT * FROM ".TABLE_PREFIX."user WHERE phone = '$phone' ");

        if (empty($user)) {
            echo "授权代理不存在";
            exit();
        }
        if ($password!=$user['password']) {
            echo "密码错误";
            exit();
        }
        //打开session
           Session_start();
           //定义session变量
        $_SESSION['user_id'] = $user['id'];
        echo "1";
    }

这里没有注册但是有个修改代码

php部分

public function modifyPwd(){
        // $phone = $_POST['phone'];
        $user_id=$_SESSION['user_id'];
        $user = $this->db->getOne("SELECT * FROM ".TABLE_PREFIX."user WHERE id = '$user_id' ");
        $oldpassword = md5($_POST['oldpsd']);
        $password1 = md5($_POST['psd1']);

        if ($oldpassword!=$user['password']) {
            echo "原密码错误";
            exit();
        }
        $this->db->exe("UPDATE " . TABLE_PREFIX . "user SET password = '$password1' WHERE id = '$user_id'");
        echo "1";
    }

html部分

<div id="content2" style="display: none;">
			<form>
				<div class="form_control">
					<label>原密码：</label><input class="required" type="password" id="oldpassword" name="oldpassword">
					<div style="display: inline" id="tip1"></div> 
				</div>
				<div class="form_control">
					<label>新密码：</label><input class="required" type="password" id="password1" name="password1">
					<div style="display: inline" id="tip2"></div> 
				</div>
				<div class="form_control">
					<label>确认密码：</label><input class="required" type="password" id="password2" name="password2">
					<div style="display: inline" id="tip3"></div> 
				</div>
				<div>
				  <input type="button" value="修改" class="alter" id="xgbtn">
				</div>
			</form>
		</div>

js表单验证以及ajax提交

$("#xgbtn").click(function(){
      // console.log(1);
      var oldpsd = $("#oldpassword").val(); 
      var psd1 = $("#password1").val(); 
      var psd2 = $("#password2").val(); 
      var num1=$("#password1").val().length;  
      var num2=$("#password2").val().length;

      if (oldpsd === "") {
          $("#tip1").html("原密码不能为空");
          $("#oldpassword").focus();
          return
      }
      if (psd1 == "") {
          $("#tip1").html("新密码不能为空");
          $("#password1").focus();
          return
      }
      if(psd1!=psd2) {  
                    $("#tip3").html("两次密码输入不一致");
                    $("#password1").focus();
                    return
                }else{  
                    $("#tip3").html("输入正确");
                }  
    $.post("{PURL('checked/modifyPwd')}",{ 'oldpsd':oldpsd,'psd1':psd1 },function(data){
      if (data == 1) {
        alert("密码修改成功")
        window.location.href="{PURL('checked')}";
      }else{
        alert(data)
      }
    })
  })                  

 

有登陆也应该有登出，【不然以为是SAO吗……

html部分没什么好记录的，一个登出按钮，给个ID---logout

js传值

 $("#logout").click(function(){ 
     $.post("{PURL('checked/logout')}",function(data){
      if (data == 2) {
          alert("退出成功，点击返回首页！");
        window.location.href="{PURL('index')}";
      }
    })
  })

php接收

public function logout(){
        unset($_SESSION['user_id']);
        
        echo '1';
    }

暂时整理这样，应该没有遗漏了_(:з」∠)_
