    Barand's post in PHP Category Path / Breakcrumb Generator was marked as the answer   
    After calling your recursive array you need finish up with a single array - you output a separate array during each iteration.
    Don't connect to db inside functions - it's the slowest part of the process and inefficient (plus you can quickly reach your connctions limit). Connect once then pass the connection to the functions.
    Don't include the separator in you results - add that when you implode (join).
    (Sorry for any delay - it's not easy to load an image of data into a database test table)
    My method...
    function retrieve_category_path($pdo, $id, &$cpa){ // DB connection // Company ID $stmt = $pdo->prepare("SELECT CONCAT(name, '::', position) as name , parent FROM category WHERE id = ? "); $stmt->execute([$id]); while($row=$stmt->fetch()){ $parent =$row['parent']; $name = $row['name']; $cpa[] = $row['name']; // append into array if($row['parent'] > 0){ retrieve_category_path($pdo, $row['parent'], $cpa); } } } $category_path_array = []; retrieve_category_path($pdo, 552, $category_path_array); $breadcrumbs = join('/', array_reverse($category_path_array)); echo $breadcrumbs; // Cars::2/Sports cars::1/Petrol::1/2 Door::0

    Barand's post in Creating array to POST with jQuery was marked as the answer   
    Yes.
    That is what I was going to suggest if you didn't want to use the hidden field approach. That way you send just a single querystring which will be handled automatically to create the $_POST array
    Perhaps
    $stmt = $pdo->prepare("INSERT INTO mytable (zoneType, zoneName, printValue) VALUES (?,?,?)"); foreach ($_POST['zoneName'] as $k => $zn) { if ($zn) { $stmt->execute([ $_POST['zoneType'][$k], $zn, $_POST['printValue'][$k] ]); } }

    Barand's post in Uncaught PDOException: SQLSTATE[HY093]: Invalid parameter number was marked as the answer   
    I wouldn't waste time on the first SELECT query.
    Place a UNIQUE key constraint on the email column then
    function createNewUser($pdo, $fname, $lname, $email, $password) { try { $sql2 = "INSERT INTO user (fname, lname, email, password) VALUES (:fname, :lname, :email, :password)"; $hashedPwd = password_hash($password, PASSWORD_BCRYPT); $stmt = $pdo->prepare($sql2); $stmt->execute([ ':fname' => $fname, ':lname' => $lname, ':email' => $email, ':password' => $hashedPwd ]); return 'User Created'; } catch (PDOException $e) { if ( str_contains($e->getMessage(), '1062 Duplicate entry')) { return "That email already exists"; } else throw $e; } }

    Barand's post in Function per field or select all data was marked as the answer   
    Whichever approach you use, do NOT connect to the database inside every function. Connect once to the db at start of each script and pass the connection to the functions. (The connection is the slowest part of the process)
    So the function calls are
    getFirstName($pdo, $id)
    getLastName($pdo, $id)
    getEmail($pdo, $id)
    getDietary($pdo, $id)
    getX($pdo, $id)
    I'd go with a single function
    $user = getUserData($pdo, $user_id); // get an array containing the user data if ($user) { $fullname = $user['firstname'] . ' ' . $user['lastname']; // use array elements as required } function getUserData($pdo, $id) { $res = $pdo->prepare("SELECT firstname , lastname , email , diet , gender , x , y , z FROM user WHERE id = ? "); $res->execute([$id]); return $res->fetch(); }

    Barand's post in PHP Date Sort using scandir() was marked as the answer   
    I don't fancy the chances of sorting your files by the dates embedded in their names.
    Instead, get the filenames, get the date of each file, store in array, then sort the dates.
    $files = glob("$dir/*.*"); $fdates = []; foreach ($files as $f) { $fdates[basename($f)] = date('Y-m-d',filemtime($f)); } asort($fdates); echo '<ul>'; foreach ($fdates as $fn => $dt) { echo "<li>$dt &ndash; $fn</li>"; } echo "</ul>"; Results wil look something like this

    Each time he wins, you record the win with this query (inserting $_SESSION['user_id'] into the table)
    INSERT INTO win_log (user_id) VALUES (?); So now you have
    TABLE: win_log +----+---------+---------------------+-----------+ | id | user_id | won | collected | +----+---------+---------------------+-----------+ | 1 | 123 | 2024-01-20 18:53:21 | NULL | | 2 | 123 | 2024-01-21 10:33:45 | NULL | +----+---------+---------------------+-----------+ On Monday he goes to collect his tokens. You check he is allowed to by...
    SELECT COUNT(*) as tot FROM win_log WHERE user_id = ? AND collected IS NULL; If the returned count is > 0 he can go ahead and collect.
    You record the collection with...
    UPDATE win_log SET collected = NOW() WHERE user_id = ? AND collected IS NULL ORDER BY won LIMIT 1; You now have
    +----+---------+---------------------+---------------------+ | id | user_id | won | collected | +----+---------+---------------------+---------------------+ | 1 | 123 | 2024-01-20 18:53:21 | 2024-01-22 19:01:25 | | 2 | 123 | 2024-01-21 10:33:45 | NULL | +----+---------+---------------------+---------------------+

    Barand's post in JavaScript Calculation Challenge: Updating Sub-Total and Total Less Amount Dynamically in a Table was marked as the answer   
    Use the javascript debugger to step through the code to see if it's doing what you expect and that the variables contain what you expect.

    Barand's post in MATCH AGAINST using my 'Terms' table and with 'Links' was marked as the answer   
    You need to join the two tables on the link_id so you match the terms to their parent link
    Do you have a specific reason for using a fulltext search? Would a simpler "LIKE" suffice. For example
    SELECT l.id as linkID , l.url , t.term FROM links l JOIN terms t ON l.id = t.link_id WHERE t.term LIKE '%ine%' OR l.url LIKE '%ine%'; linkID | url | term ----------+----------------+----------------- 2 | page2.php | zine 2 | page2.php | magazine 2 | page2.php | online
