PDO - passing a field name as a variable

Question

I\'m just migrating my code from mysql_query style commands to PDO style and I ran into a problem. THe old code looked like this :

$query_list_menu = \"SELE         


        

Answer 1

There is no good and safe way to select just one field from the record based on the user's choice. The most sensible solution would be to select the whole row and then return the only field requested

$sql = "SELECT * from myl_menu_hide_show WHERE id=?";
$stmt = $db->prepare($query_list_menu);
$stmt->execute([$_GET['id']]);
$row = $stmt->fetch();
return $row[$_GET['section_name']] ?? false;
