My controller code
.controller(‘ClassCtrl’, function ($scope, $http) {

  var link = '';
  var userid = JSON.parse(localStorage.getItem('loginDetails'));

  $, {userid: userid}).success(function(res){
.error(function(err) {

My php code.

<?php header("Access-Control-Allow-Origin: *"); require_once('connection.php'); $post_data = file_get_contents('php://input'); $request = json_decode($post_data); //var_dump($post_data); $userid= $request->userid; $subject_sql ="SELECT SubjectName FROM subjects WHERE userid = '" .$userid. "' "; $result = $con->query($subject_sql); while($re=$result->fetch_assoc()) { $res_array[] = $re; } echo json_encode($res_array); ?>
