php - Store variable in Session -

i want store user_level mysql db of user submits form in $_session code this:

    <form id='login' action='<?php echo $fgmembersite->getselfscript(); ?>' method='post' accept-charset='utf-8'>     <fieldset >     <?php     if(isset($_post['submitted']))     {  session_start();     if($fgmembersite->login())        {          $mysqli = new mysqli('host', 'name', 'psw', 'db');                 if ($result = $mysqli->query("select user_level users username='$username'")) {                   $_session['user_level'] = $result;                  }              $fgmembersite->redirecttourl("loginhome.php");         }             }      ?>      <legend>login</legend>      <input type='hidden' name='submitted' id='submitted' value='1'/>      <div class='short_explanation'>* benötigte felder</div>      <div><span class='error'><?php echo $fgmembersite->geterrormessage(); ?></span></div>     <div class='container'>         <label for='username' >benutzername*:</label><br/>         <input type='text' name='username' id='username' value='<?php echo $fgmembersite->safedisplay('username') ?>' maxlength="50" /><br/>         <span id='login_username_errorloc' class='error'></span>     </div> 

now checked on site, got redirected print_r($_session); , result:

[user_level] => mysqli_result object ( [current_field] => [field_count] => [lengths] => [num_rows] => [type] => ) 

can explain me happens there? or went wrong?

this not fix issue session should started @ utmost top of script.

<?php if (!isset($_session)) {     session_start(); }  // ... other code ... 

there issue query. should use like:

$conn = new mysqli('host', 'username', 'password', 'database'); $stmt = $conn->prepare("select * table id = ?"); $stmt->bind_param("s", $editid); $stmt->execute(); $result = $stmt->get_result(); $row = $result->fetch_assoc();  print_r($row);
