插入 Select + 插入值（）

Question

        $query = "INSERT INTO tbl_event(mcode, packagetype)
                SELECT fcode, packagetype
                FROM tbl_family_accounts
                WHERE id = '$uID'
            ";

The columns mcode and packagetype is from the table tbl_family_accounts and i managed to successfully insert it.

1. How can i improve my query to insert the event_title and event_descrip from <form> or my website.

Answer 1

You can put literals into the SELECT list. In mysqli or PDO you would use placeholders for them, and bind them to the POST parameters.

$query = "INSERT INTO tbl_event(mcode, packagetype, event_title, event_descrip)
    SELECT fcode, packagetype, ?, ?
    FROM tbl_family_accounts
    WHERE id = ?
";
$stmt = $conn->prepare($query);
$stmt->bind_param("sss", $_POST['title'], $_POST['description'], $uID);
$stmt->execute();

Replace the $_POST indexes with the actual names from your form.
