javascript - AJAX is running error function instead of success function -


i trying database login work. ajax call keeps running error function instead of success, , struggling understand why.

function dologin() {     var formdata = convertformtojson("#login-form");     console.log('login data send: ', formdata);      $.ajax({         url: 'php/login-session.php',         type: 'post',         datatype: 'json',         data: formdata,         success: function(logindata) {             console.log('login data returned: ', logindata);              var status = logindata['status'];             if(status == "fail"){                 $("#loginerror").html(logindata['msg']);                 $("#loginerror").cs('display', 'block');             } else {                 getuserprofileinfo();                 $("login-form").trigger('reset');             }         },         error: function(jqxhr, textstatus, errorthrown){             console.log(jqxhr.statustext, textstatus);         }     }); }

the console logs:

login data send: object {loginusername: "test", loginpassword: "test"}

ok parsererror

my login-session.php code is:

<?php  if (session_status() == php_session_none) {     session_start(); }  $dbhost = 'localhost'; $dbuser = 'root'; $dbpass = 'root'; $dbname = 'anamadeus';  $methodtype = $_server['request_method']; $data = array('status' => 'fail', 'msg' => '$methodtype');  if($methodtype === 'post'){     //check ajax     if(isset($_server['http_x_requested_with']) && strtolower($_server['http_x_requested_with']) == 'xmlhttprequest') {          if(isset($_post['loginusername']) && !empty($_post['loginusername']) && isset($_post["loginpassword"]) && !empty($_post["loginpassword"])){              // data post , store in variables             $username = $_post["loginusername"];             $password = $_post["loginpassword"];              try {                 $conn = new pdo('mysql:host=$dbhost;dbname=$dbname', $dbuser, $dbpass);                 $conn->setattribute(pdo::attr_errmode, pdo::errmode_exception);                  $sql = 'select * user username = :log , password = :pwd';                  $statement = $conn->prepare($sql);                 $statement->execute(array(":log" => $username, ":pwd" => $password));                  // should 1 if there's user user value , password value                 $count = $statement->rowcount();                  if($count > 0){                     $rows = $statement->fetchall(pdo::fetch_assoc);                     $returnedusername = $rows[0]['username'];                     $returnedpassword = $rows[0]['password'];                      $_session['username'] = $returnedusername;                     $_session['loggedin'] = true;                      $sid=session_id();                     $data = array("status" => "success", "sid" => $sid);                 } else {                     $data = array("status" => "fail", "msg" => "user name and/or password not correct.");                 }             } catch(pdoexception $e) {                 $data = array("status" => "fail", "msg" => $e->getmessage());             }          } else {             $data = array("status" => "fail", "msg" => "either login or password absent.");         }      } else {         // not ajax         $data = array("status" => "fail", "msg" => "has ajax call.");     } } else {     // simple error message, taking post requests     $data = array("status" => "fail", "msg" => "error: post allowed."); }  echo json_encode($data, json_force_object);  ?>

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
