1. Front desk ajax data submission

The backend management system logs in to $("# login_btn") .click (function () {var username = $.trim ($("# username"). Val ()); var password = $.trim ($("# password"). Val ()); if (username = = ") {alert (" Please enter user name "); return false } else if (password = = "") {alert ("Please enter password"); return false;} / / ajax to verify var data= {username:username,password:password}; $.ajax ({type: "POST", url: "_ _ CONTROLLER__/check_login", data:data, dataType:'json', success:function (msg) {/ / alert (msg) If (msg==1) {_ window.location.href = "{: U ('Index/personal')}";} else {alert ("login failed, please try again!);});})

two。 Background check:

* * / public function check_login () {$password=I ('param.password'); $username=I (' param.username'); $data ["name"] = $username; $user=M ('systemuser'); $list=$user- > where ($data)-> find (); $return=0 If ($listings = "") {if ($list ['password'] = = md5 ($password) & & $list [' status'] = = 1) {/ / login time and login IP $public = new PublicController (); $lastlogonip=$public- > ip_address (); $time=$time=date ("Y-m-d H:i:s", time ()); $where=array ('id'= > $list [' id']) $user- > where ($where)-> save (array ('lastlogonip'= > $lastlogonip,'lastlogontime'= > $time)); $this- > login ($list); $return=1;// login success}} else {$return=2;// login failure} $this- > ajaxReturn ($return);}
