how can add new field by db code

[al3bed]

hello,

I have this code in my plugin:

PHP Code:

$vbulletin->db->query_write(" 
            INSERT INTO `". TABLE_PREFIX ."profilefield` 
            (`profilefieldid` ,`profilefieldcategoryid` ,`required` ,`hidden` ,`maxlength` ,`size` ,`displayorder` ,`editable` ,`type` ,`data` ,`height` ,`def` ,`optional` ,`searchable` ,`memberlist` ,`regex` ,`form` ,`html` ,`perline`) 
            VALUES (NULL, '0', '0', '0', '16', '16', '', '1', 'input', NULL , '0', '0', '0', '0', '0', '', '0', '0', '0') 
        ") 


this is work to bulid field but without title and desc.
and another thing : I want displayorder column = profilefieldid like when I add a field by admincp/profilefield.php

I try to insert phrase to be like this:
varname: fieldx_title (which x is field id but I don't know how to find it)
fieldname: cprofilefield
