Benutzerdefiniertes php Login-Formular: mit einem modalen

Question

Ich versuche, meine Login-PHP funktioniert. Ich kann nicht finden, was falsch ist. Ich hatte es schon früher funktioniert, aber es hörte auf einmal auf. Ich benutze auch Bootstrap, aber ich denke nicht, dass das irgendwelche Probleme verursachen würde. Alles zwischen dem PHP und dem Formular scheint übereinzustimmen. Ich benutze ein JavaScript und CSS modal für das Login-Formular, aber ich denke nicht, dass dies auch Auswirkungen hätte.

PHP:

<?php 
session_start(); 
include_once 'dbconnect.php'; 

if(isset($_SESSION['usr_id'])) { 

echo "Successfully Logged In!"; 

//header("Location: index.php"); 

} 

if (isset($_POST['login'])) { 

$email = mysqli_real_escape_string($con, $_POST['email']); 

$password = mysqli_real_escape_string($con, $_POST['password']); 

$result = mysqli_query($con, "SELECT * FROM users WHERE email = '" . $email . "' and password = '" . md5($password) . "'"); 
?> 
<!--<script> 
    alert("<?php echo 'Result is: '.$result; ?>"); 
</script> --> 
<?php 
$row = mysqli_fetch_array($result); 
echo $row; 

if ($row != NULL) { 

    $_SESSION['usr_id'] = $row['id']; 

    $_SESSION['usr_name'] = $row['name']; 

    // header("Location: index.php"); 

} else { 

    $errormsg = "Incorrect Email or Password!!!"; 

} 

} 

?> 

Hier wird die Anmeldungs ​​modal mit der Form:

<!-- The Modal --> 
    <div id="login" class="modal"> 

<!-- Modal content --> 
    <div class='js-fade fade-in is-paused'> 
     <div class="modal-content"> 
      <span class="close" data-dismiss="modal">x</span> 
       <form role="form" action="index.php" method="post" name="loginform"> 

             <fieldset> 

              <legend>Login</legend> 



              <div class="form-group"> 

               <label for="name">Email</label> 

               <input type="text" name="email" id="email" placeholder="Your Email" required class="form-control" /> 

              </div> 



              <div class="form-group"> 

               <label for="name">Password</label> 

               <input type="password" name="password" id="password" placeholder="Your Password" required class="form-control" /> 

              </div> 


              <div class="form-group"> 

               <input type="submit" name="login" value="login" class="btn btn-info login" role="button" /> 

              </div> 

             </fieldset> 
              <div class="signupbtn"> 
               <li><a href="signup/index.php" class="noaccount btn btn-info" id="signupbtn">Don't have an account? Sign Up here.</a></li> 
              </div> 
            </form> 
     </div> 

    </div> 
</div> 

Navbar:

<!-- Nav Bar --> 
<nav class="navbar navbar-default navbar-fixed-top navbar-left"> 
    <div class="container"> 
     <div class="navbar-header"> 
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"> 
       <span class="icon-bar"></span> 
       <span class="icon-bar"></span> 
       <span class="icon-bar"></span> 
      </button> 
       <a class="navbar-brand brand" href="#" style="font-family: Warnes">Unleasht</a> 
     </div> 
    <div class="collapse navbar-collapse"> 
     <ul class="nav navbar-nav"> 
      <li class="navbarli"><a href="#" class="navbarli">HOME</a></li> 
      <li class="navbarli"><a href="#about" class="navbarli">ABOUT</a></li> 
      <li class="navbarli"><a href="#music" class="navbarli" data-toggle="collapse" data-target=".navbar-collapse.in">MUSIC</a></li> 
      <li class="navbarli"><a href="#contact" class="navbarli" data-toggle="collapse" data-target=".navbar-collapse.in">CONTACT</a></li> 
     </ul> 
     <ul class="nav navbar-nav navbar-right"> 

      <?php 
      function loggedIn(){ 
      if(isset($_SESSION['usr_id'])) 
      { echo '<li class="dropdown"> 
        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">'. $_SESSION['user'] .'<span class="caret"></span></a> 
        <ul class="dropdown-menu"> 
         <li><a href="#">'. $_SESSION['usr_name'] .'</a></li> 
         <li><a href="#">Account</a></li> 
         <li role="separator" class="divider"></li> 
         <li><a action="login/logout.php">Logout</a></li> 
        </ul> 
       </li>'; 
      }else{ 
       unset($_SESSION['usr_id']); 
       echo '<li><a href="#login" class="navbarli" data-toggle="modal" data-target="#login" id="loginbtn"><span class="glyphicon glyphicon-log-in navbarli"></span> Login</a></li>'; 
       } 
      } 
      loggedIn(); 
      ?> 

     </ul> 
    </div><!--/.nav-collapse --> 
    </div> 
</nav> 

Was mache ich falsch?

Answer 1

Sie können nicht gesetzt $ _SESSION [ ‚usr_id‘], nachdem Sie alle Header gesendet haben, versuchen Sie folgenden Code ein:

<?php 
session_start(); 
include_once 'dbconnect.php'; 
if(isset($_SESSION['usr_id'])) { 
    echo "Successfully Logged In!"; 
}elseif (isset($_POST['login'])) { 
    $email = mysqli_real_escape_string($con, $_POST['email']); 
    $password = mysqli_real_escape_string($con, $_POST['password']); 
    $result = mysqli_query($con, "SELECT * FROM users WHERE email = '" . $email . "' and password = '" . md5($password) . "'"); 
    if (mysqli_num_rows($result)==1) { 
     $row = mysqli_fetch_array($result); 
     $_SESSION['usr_id'] = $row['id']; 
     $_SESSION['usr_name'] = $row['name']; 
     echo "OK fine"; 
    } else { 
     echo "Incorrect Email or Password!!!"; 
    } 
} 
?>
