login modal

<!--login modal --> <?php require_once( "./inc/connect.inc.php" ); ?> <div class="modal fade col-sm-4 col-sm-offset-4" id="login" role="dialogue">     <div class="modal-dialogue">         <div class="modal-content">         <form action="" method="post">             <div class="modal-header">                 <h4>login</h4>             </div>             <div class="modal-body row">                     <div class="form-group">                     <div class="col-sm-12">                         <input type="text" class="form-control" id="username" placeholder="email address">                     </div>                     <div class="col-sm-12">                         <input type="password" class="form-control" id="userpassword" placeholder="password">                     </div>                     <!-- end address form -->                 </div>             </div>             <div class="modal-footer">                             <button type="button" class = "btn btn-warning" id="loginbutton" value="login" name="/login">login</button><a class = "btn btn-warning" data-dismiss = "modal">cancel</a>             </div>                 </form>                 <script>                 $(document).ready(function(){                     $("#loginbutton").click(function(){                         console.log("test123");                         var username = $("#username").val();                         var password = $("#userpassword").val();                         $.post("../login.php", {login:username, password:password}, function(data){                         console.log(data);                     });                 });             });             </script>         </div>     </div> </div>

login.php

<?php     if(isset($_post['login'])){     echo "<br>login set<br>";     $user_login = strip_tags($_post['login']);       echo $user_login."<br>";     $password_login = strip_tags($_post['password']);     echo $password_login."<br>";     $password_login = md5($password_login);     echo $password_login."<br>";     $sql = mysql_query("select * users email='$user_login' , password='$password_login' limit 1") or die(mysql_error());     $usercount = mysql_num_rows($sql);     echo $usercount."<br>";     if($usercount == 1){         while($row = mysql_fetch_array($sql)){              $user_id = $row["id"];             $user_fname = $row["first_name"];             $user_lname = $row["last_name"];             $user_membersince = $row["date"];          }          $_session['user_email'] = $user_login;         $_session['user_fname'] = $user_fname;         $_session['user_lname'] = $user_lname;         $_session['user_membersince'] = $user_membersince;          echo("logged in!");      }else {         echo("invalid username/password");     } } ?>

connection.inc.php

<?php $db = mysql_connect("localhost:3306", "urbanas8_login", "ure1982*") or die(mysql_error); mysql_select_db('urbanas8_db', $db) or die(mysql_error()); ?>

there problem in username through logging mysql. error message shows username 'urbanas8' connection file shows 'urbanas8_login'.

you have not included file "connection.inc.php" in login.php

i recommend use mysqli instead of mysql. deprecated.

<?php  //conection:  $link = mysqli_connect("myhost","myuser","mypassw","mybd") or die("error " . mysqli_error($link));   //consultation:   $query = "select name mytable" or die("error in consult.." . mysqli_error($link));   //execute query.   $result = $link->query($query);   //display information:   while($row = mysqli_fetch_array($result)) {    echo $row["name"] . "<br>";  }  ?>
