Validation from DB

Ok, here is my problem. I have this website where my user will log in. I have this function that list all the permissions possible function lista_permissoes() { $result = mysql_query("select * from permissoes ORDER BY ordem"); while ($row4 = mysql_fetch_array($result,MYSQL_ASSOC)) { $permissoes[] = $row4; } return $permissoes; }; And this function that., I suppose, should check if the group that the person belongs have this permission or not function validar($grupo,$perm) { $permissao = mysql_query("select id_permissoes from grupos_permissoes where id_grupos = $grupo") or die ('query failed'); $row = mysql_fetch_array($permissao); $acesso = 0; for ($i = 0 ; $i<=sizeof($row); $i++){ if (array_key_exists($perm, $row)) { $acesso = 1; } } return $acesso; } So, if the permission in question belongs to the group, it would return $acesso 1, right? So, putting the 2 of them together, it would work like this: $permis = lista_permissoes(); for($i=0; $i<=sizeof($permis); $i++) { $permiss = $permis[$i]; //here the SESSION is the id of the group of the user $aux = validar($_SESSION['ciranda']['id_grupo'],$permiss['id']); if ($aux) { ?> <a href="index-2.php?permissao=<?= $permiss['id'] ?>" class="permiss"> <?= $permiss['nome']?> </a><hr align="left" width="150"> <? } } Well, I dont get any error, but I can get only the first permission validated... its like the function is not looping back. Can anyone see what is wrong? Thank you in advance, Dani --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
