سؤال

I'm getting this error on my page. I tried to comment out the "$mine" but it then allows me to add my own profile. I need to say that if the page or user isn't me, then show the add or remove friend option. Any suggestions? I got this code from this youtube video : https://www.youtube.com/watch?v=Wgbmgf84ZOo

<?php
    require_once('includes/class-query.php');
    require_once('includes/class-insert.php');


    if ( !empty ( $_POST ) ) {
        if ( $_POST['type'] == 'add' ) {
            $add_friend = $insert->add_friend($_POST['user_id'], $_POST['friend_id']);
        }

        if ( $_POST['type'] == 'remove' ) {
            $remove_friend = $insert->remove_friend($_POST['user_id'], $_POST['friend_id']);
        }
    }

    $logged_user_id = 1;


    if ( !empty ( $_GET['uid'] ) ) {
        $user_id = $_GET['uid'];
        $user = $query->load_user_object($user_id);

        if ( $logged_user_id == $user_id ) {

        }
    } else {
        $user = $query->load_user_object($logged_user_id);

    }

    $friends = $query->get_friends($logged_user_id);
?>

المحلول

This is a notice, not a fatal error. the line if(!$mime) is returning the notice. Change it to if(!isset($mime)) and the error will be suppressed:

<p>Email Address: <?php echo $user->user_email; ?></p>
            <?php if ( !isset($mine) ) : ?>
                <?php if ( !in_array($user_id, $friends) ) : ?>
