Question

This question already has an answer here:

• “Notice: Undefined variable”, “Notice: Undefined index”, and “Notice: Undefined offset” using PHP 28 answers

I have a list of profiles, and i need to make the user able to select the individual profile in a link.

I found this question and tried to follow it, but it doesnt quite work as i hoped it would: Displaying a user profile page PHP

The file to display all profiles on the page looks like this:

foreach ($rows as $row) {
    echo '<a class="viewProfile" href="user.php?id=' . $r['UID']. '"><button>View Profile</button></a>';
}

But when i click the link the UID doesn't get posted in the URL, and it just looks like this: domain/user.php?id=

Update: With help from you guys i got the UID posted into the URL. Thanks! And as jothi stated $id=$_GET['id'];

</div>

Answer 1

That's because $r['UID'] is not defined. You are enumerating some $row, so I assume that you mean $row['UID'].

If it doesn't work, please, post the result of this line, just before you foreach ($rows as $row)

echo print_r($rows);
