[virla]

en esta parte del codigo creo que esta lo que tu dices pero no se como hacerlo

function blocks($side) {
global $storynum, $prefix, $multilingual, $currentlang, $db, $admin, $user;
if ($multilingual == 1) {
$querylang = "AND (blanguage='$currentlang' OR blanguage='')";
} else {
$querylang = "";
}
if (strtolower($side[0]) == "l") {
$pos = "l";
} elseif (strtolower($side[0]) == "r") {
$pos = "r"; ////donde r es la columna donde quiero cambiar
} elseif (strtolower($side[0]) == "c") {
$pos = "c";
} elseif (strtolower($side[0]) == "d") {
$pos = "d";
}
$side = $pos;
$sql = "SELECT bid, bkey, title, content, url, blockfile, view, expire, action, subscription FROM ".$prefix."_blocks WHERE bposition='$pos' AND active='1' $querylang ORDER BY weight ASC";
$result = $db->sql_query($sql);
while($row = $db->sql_fetchrow($result)) {
$bid = intval($row['bid']);
$title = stripslashes(check_html($row['title'], "nohtml"));
$content = stripslashes($row['content']);
$url = stripslashes($row['url']);
$blockfile = $row['blockfile'];
$view = intval($row['view']);
$expire = intval($row['expire']);
$action = $row['action'];
$action = substr("$action", 0,1);
$now = time();
$sub = intval($row['subscription']);
if ($sub == 0 OR ($sub == 1 AND !paid())) {
if ($expire != 0 AND $expire <= $now) {
if ($action == "d") {
$db->sql_query("UPDATE ".$prefix."_blocks SET active='0', expire='0' WHERE bid='$bid'");
return;
} elseif ($action == "r") {
$db->sql_query("DELETE FROM ".$prefix."_blocks WHERE bid='$bid'");
return;
}
}
if ($row[bkey] == admin) {
adminblock();
} elseif ($row[bkey] == userbox) {
userblock();
} elseif ($row[bkey] == "") {
if ($view == 0) {
render_blocks($side, $blockfile, $title, $content, $bid, $url);
} elseif ($view == 1 AND is_user($user) || is_admin($admin)) {
render_blocks($side, $blockfile, $title, $content, $bid, $url);
} elseif ($view == 2 AND is_admin($admin)) {
render_blocks($side, $blockfile, $title, $content, $bid, $url);
} elseif ($view == 3 AND !is_user($user) || is_admin($admin)) {
render_blocks($side, $blockfile, $title, $content, $bid, $url);
}
}
}
}
}
pero de verdad no me doy una idea de donde tengo que hacer el cambio espero que me des una mano
gracias
