Look up the function fetch_userinfo (do a search in your files for it, I can't remember which file it is in).

[MyPornLife.info]

i looked in function.php file & found some code...based on those i wrote these code

PHP Code:

$userid = $_REQUEST['u'];

$userinfo = $db->query_read("SELECT username, usertitle, usergroupid FROM " . TABLE_PREFIX . "user WHERE userid=$userid");
$userinfo = $vbulletin->db->fetch_array($userinfo);

$usergroup = $userinfo['usergroupid'];

$username = $userinfo['username'];
$musername = $vbulletin->usergroupcache["$usergroup"]['opentag'] . $username . $vbulletin->usergroupcache["$usergroup"]['closetag'];

$usertitle = $userinfo['usertitle']; 


so it can show username (with html mark) by $musername & that user's title (or custom title) by $usertitle

but what about Ranks

plz help me about RANKS

You might want to familiarize yourself with the vBulletin API. In the functions, you will find fetch_rank.

Isn't his SQL query open to injection attacks?
Unless vB's query_read() function protects against it.

Like I told him, he should use the existing functions. And yes, he should use the input cleaner also.

guys english plz im not an advance vb coder.

1st of all what is "SQL query open to injection attacks". how can i solve it?

lynne u told about existing functions !

could u guys plz, plz & plz post some PHP code here as an example? plz stop telling look here or there...find it....its really not an easy thing for a novice coder

[Lynne]

The existing php code is in the vbulletin files. Did you try a search in the files for fetch_userinfo? It shows up many times and you can see the use of it. These are some excepts from a page I use:

First the cleaner is used on the userid that is passed from the form:

PHP Code:

$vbulletin->input->clean_array_gpc('r', array(
    'f'    => TYPE_UINT,
    'do'  => TYPE_STR,
    'u'    => TYPE_UINT,
)); 


then the userinfo is obtained a few lines after and I grab the username (and other stuff later):

PHP Code:

      $userinfo = fetch_userinfo($vbulletin->GPC['u']);
        $username = $userinfo['username']; 


Take a look at the function itself to see all the info obtained in the query - in includes/functions.php

There are articles you can read on the user of the vbulletin cleaner and on writing secure code.

thank you Lynne. thank you very much.
especially for

PHP Code:

fetch_userinfo($vbulletin->GPC['u']); 


but still cant do it for Rank
i tried something like this

PHP Code:

require_once('./includes/functions_ranks.php');

$vbulletin->input->clean_array_gpc('r', array(
    'f'    => TYPE_UINT,
    'do'  => TYPE_STR,
    'u'    => TYPE_UINT,
)); 

$rank = fetch_rank($vbulletin->GPC['u']);
$rank = $rank['rankimg'];

echo $rank; 


showing nothing


can u plz help me....plz

Did you look the function up in the API like I suggested? The API will tell you what file it is in. Or, do a search in the files for the function to find what file it is in and then make sure you either include the file in your code, or copy/paste the function into your code.
