Help with Index and Mysqli error

#1
Hey again Blush 

I got these 2 errors and wanted to see how to fix them:

1.
Severity: Notice

Message: Undefined index: email

2.
Severity: Warning

Message: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given



For these lines of code:
$email=$_SESSION['email'];
$sql1="select * from users where user_email='$email'";
$run=mysqli_query($con,$sql1);
echo "<h1>List of friends</h2>";
while($row=mysqli_fetch_array($run))
{
 $id=$row['id'];
$sql="select * from friend where receive_request='$id' and status='1'";
$run1=mysqli_query($con,$sql);
while($row1=mysqli_fetch_array($run1))
{
    $name=$row1['request_sent'];
    $sql2="select * from users where user_email='$name'";
    $run2=mysqli_query($con,$sql2);
    while($row2=mysqli_fetch_array($run2))
    {
        $namee=$row2['user_name'];
        echo $namee."<br/>";
    }

How to fix these? Thank ya kindly

Why do you keep using old php code?

If you need to use old code convert it to CodeIgniter.
What did you Try? What did you Get? What did you Expect?

Im using code that I became interested in form Git. This was a repo for a friend's list (like in FB) that caught my eye. The situation is that I cant find many current tutorials pertaining to what I want that deals with CI. Will work on conversion for CI Smile

It's full of security holes, you need to rewrite it from scratch.

The $_session['email'] does not exist find out why there is no $_session['email'] and it should fix your second problem

Most likely it is a facebook style time lime not a list.

Look for a facebook style time line code for CodeIgniter.
