linking user-id and feedback-id after user login

0
0

Iam strugling with my issue to link user to his feedback he posted. I have feedback.php page and it is available for members and non-members to submit feedback to admin. I have a feature where if user login and send feedback while he's loggedin, he will be able later-on to preview his feedbacks in his profile page.

I created 3 tables in my Dbase which are(user, feedback, user-info).

User tbale has: ('userid' ,'fname', 'lname', 'username', 'email', 'password') userid(pk)

feedback table has:('feedbackid' ,'feedbacktitle', 'name', 'email', 'comment', 'datetime') feedbackid (pk)

user-info table has: ('id', 'feedback-id', 'user-id') id(pk) feedback-id(fk) user-id(fk)

I tried to add (Fk) in user table and feedback table to display the user who sent the feedback but couldn't. and then I created the user-info in attempts to get what I want but no-thing.

This is my feedback.php page:

<?php
require('Connections/portdb.php');
//start session
if(!isset($_SESSION))
{
    session_start();
}

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

        $feedbacktitle  = mysql_real_escape_string ( $_POST['feedbacktitle']);
        $name  = mysql_real_escape_string ( $_POST['name']);
        $email = mysql_real_escape_string($_POST['email']);
        $comment = mysql_real_escape_string($_POST['comment']);
        $datetime= mysql_real_escape_string (date ("y-m-d h:i:s")); //date time

$sql= "INSERT INTO feedback(feedbacktitle, name, email, comment, datetime)
VALUES('$feedbacktitle', '$name', '$email', '$comment', '$datetime')";
$result = mysql_query($sql);

if($result){
echo "Successful";
echo "<br>";

echo "<a href='../main.php'>Go back to main page</a>";
}
else {
echo "Sorry ! an error happend.";
}
}
mysql_close();
?>

$getLogin = mysql_query("SELECT * FROM user WHERE username='$username' AND password = '$password' ");
$row = mysql_fetch_array($getLogin);

if(mysql_num_rows($getLogin) > 0)
{
    $_SESSION['loggedin']= true;
    $_SESSION['userid']= $row['userid'];
    $_SESSION['username']= $row['username'];
    $_SESSION['usertype']= 'user';
    session_write_close();
