Bonjour à tous,
J'ai un petit probleme, je vien de faire 3 champs pour un affichage par date

jour = INT mysql
mois= INT mysql
annes = INT mysql


pouvez-vous m'aider à les trier svp, voici mon code php
<?php




$total=0;
$parpage=5;
if(isset($_GET['page']))
$page=$_GET['page'];
else
$page=0;

if(isset($_GET[catpodcasts])){

$cat=$_GET[catpodcasts]; //LORSQU IL A UNE CATEGORIE
$commaff= mysql_query("SELECT * FROM ".T_PODCAST." WHERE idcat='$cat' ORDER BY id DESC LIMIT $page,$parpage ");
$totalid=mysql_query("SELECT * from ".T_PODCAST." WHERE idcat='$cat'");

}else{
$commaff= mysql_query("SELECT * FROM ".T_PODCAST." ORDER BY annes, mois, jour LIMIT $page,$parpage");
$totalid=mysql_query("SELECT * from ".T_PODCAST."");

}
while ($donnees = mysql_fetch_array($totalid))
{
$total++;
}


$repon = mysql_num_rows($commaff);
if(!$repon) {
echo'<div align="center">Aucun podcast dans cette catégorie</div>';
}




while ($donnees = mysql_fetch_array($commaff))
{
$max=200;
$chaine=$donnees['description'];
if(strlen($chaine)>=$max)
{
$chaine=substr($chaine,0,$max);
$espace=strrpos($chaine," ");
if($espace)
$chaine=substr($chaine,0,$espace);
$chaine .= ' ...';
}
$numero=$donnees[0]+102;
