How 2 Insert Data Into Forum's Database Via A Form

[Dismounted]

Yes I did notice that, and you also specified TYPE_STR. This, however, does nothing for SQL injection, it merely verifies that it is a string. You need to escape dangerous characters (such as single quotes).

PHP Code:

$db->query_write("
    INSERT INTO " . TABLE_PREFIX . "$testtable
    (testcolumn)
    VALUES
    (" . $db->escape_string($vbulletin->GPC['testform']) . ")
");

Actually I replaced my write query with yours, but the script started giving me database error

so I surrounded the value by single quot, so it became like this:

PHP Code:

('" . $db->escape_string($vbulletin->GPC['testform']) . "') 


and it seemed to be just fine however when I check the table through the phpMyAdmin I found new record has been added as it supposed to be, except that it is empty

do you have any idea
