Question

我尝试制作一个表单，允许用户更改AND向会话用户添加一些值。

我没有登录，这是我的一个老朋友。他没有很好地评论代码，评论对我来说很有用，这对于php和SQL来说是相对较新的。

如何从$ _SESSION更新用户值？

index.php代码：

<?php

include('template.php');
$role = array("1"=> "admin.php", "2"=> "useradmin.php", "3"=> "user.php"); //Visar vilken sida varje roll skall skickas vid inlogg.

if(isset($_POST['email']))
{
  $query = <<<END
  SELECT email, password, userID, fname, company, tel, role FROM user
  WHERE email = '{$_POST['email']}'
  AND password = '{$_POST['password']}'
END;
$res = $mysqli->query($query);
if ($res->num_rows > 0)
{
    $row = $res->fetch_object();
    $_SESSION["email"] = $row->email;
    $_SESSION["fname"] = $row->fname;
    $_SESSION["tel"] = $row->tel;
    $_SESSION["company"] = $row->company;



$query2 = <<<END
  SELECT role FROM user 
  WHERE role = '{$row->role}'

END;
  $res2 = $mysqli->query($query2) or die ($mysqli->error);
  $row2 = $res2->fetch_object();

  header("Location: ".$role[$row2->role]);
  }
  else
  {
    echo "Fel email eller lösenord.";
  }
}

带有HTML文件的

settings.php代码：

<?php
include('template.php');
 $content = <<<END
 <div class="row">
         <div class="container">
            <div class="jumbotron">
          <div class="container">
          <h2> Användarinställningar för <strong>{$_SESSION['fname']}</strong></h2>
<form action="" metod="POST">
    <ul class="usersettings">
        <li> Förnamn: <br>
        <input type="text" name="fname" value="{$_SESSION['fname']}">
        </li>
        <li> Email: <br>
        <input type="text" name="email" value="{$_SESSION['email']}">

    </ul>
</form> 

          </div><!-- Stänger jumbotronen --> 
         </div><!-- Stänger container --> 
      </div><!-- Stänger row --> 
END;
  echo $navigation_user;
  echo $header;
  echo $content;
  ?>

registration.php代码：

if(isset($_POST['email']))

{
function genRandomString($length = 10) {
    $characters = "0123456789abcdefghijklmnopqrstuvwxyz";
    $string = '”';
    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, strlen($characters))];
    }

    return $string;
}
  $password= genRandomString();
  $licenseID= genRandomString();

    $query = <<<END

    INSERT INTO user(email, company, courseID, antal, password, licenseID)

    VALUES('{$_POST['email']}','{$_POST['company']}','{$_POST['courseID']}', '{$_POST['antal']}', '$password','$licenseID');
END;
    $mysqli->query($query);


echo 'Nya licenser har lagts till i databasen';

}
 $content = <<<END

页面上的管理员添加了新用户，而不是用户，因此某些值为NULL。
