I have shared with you the specific code for ajax to submit the mobile phone number to the database and return the status value for your reference. The specific content is as follows

 $(function(){
 $(&#39;.agree_regi&#39;).click(function(){
  var phone = $.trim($("#phone").val());
  if(phone == ""){
  NewAlert(2,"请输入手机号",null);
  return false;
  }else{
   var reg = /^0?1[3|4|5|8|7][0-9]\d{8}$/;
   if (!reg.test(phone)) {
    NewAlert(2,"请输入有效的手机号码",null);
     return false;
    }
  }
  var data ={
  phone:phone,
  };
  
  $.ajax({
  type:"POST",
  url:"{:U(&#39;Register/PhoneFind&#39;)}",
  data:data,
  success:function(msg){
   if(msg==&#39;0&#39;){
   NewAlert(2,"手机号有误",null);
   }
   if(msg==&#39;1&#39;){
   NewAlert(2,"该手机号已经注册，请直接登录",null);
   }
   if(msg==&#39;2&#39;){
   location.href="/Register/Regowner?phone="+phone;
   }
   if(msg==&#39;3&#39;){
   location.href="/Register/Regnest?phone="+phone;
   } 
  }
  });
 });
 });
</script>

Copy after login

The background receives the ajax submitted value, queries the database, and returns it.

public function PhoneFind(){
  if(!empty(I(&#39;param.phone&#39;))){ //I方法获取post提交的值
   $phone = I(&#39;param.phone&#39;);
   $user = M("cuser");
   $res=$user->where(array(&#39;phone&#39; =>$phone))->find(); //去数据库查询一条，并以数组返回
   if (!empty($res[&#39;password&#39;])) {
    $status=1;//密码存在，用户直接登录
   }elseif(!empty($res)){
    $status=2;//存在，没有密码，设置密码，是业主
   }else{
    $status=3;//不存在，是游客，注册
   }
  }else{
   $status=0;//手机号有误
  }
  $this->ajaxReturn($status);         //返回状态值给前台
 }

Copy after login
