Gestion checkbox avec php

Il faudrait le code source HTML du formulaire qui a généré ce résultat.
Et donne le code PHP qui précède ton for : comment récupères-tu $nbr_entrees ? etc ...
Et ce serait royal si tu pouvais donner la sortie d'un

print_r($_GET)

[ ou $_POST si c'est en post) ] également (mais si c'est trop compliqué, laisse tomber).

Merci pour ton aide, voici le code enier

<?php
include("parametres.php");

$DB_link = mysql_connect($host,$user,"");
$requette = " select * from $table where actif = '1' order by date desc, heure desc ";

$resultat = mysql_db_query($database,$requette,$DB_link);
$nbr_entrees = mysql_num_rows($resultat);
$a = array();

function affichage_unique($var)
{
echo "<tr bgcolor=\"#CCCCCC\">";
//Date
$tmp = $var;
echo "<th width=\"10%\" align=left nowrap>".$tmp."</th>";
//email
echo "<th width=\"12%\" align=left nowrap>".$tmp."</th>";
//Type de Message
echo "<th width=\"8%\" align=left nowrap>".$tmp."</th>";
//Message
echo "<th width=\"500\" align=left nowrap>".$tmp."</th>";
//Bouton Repondre
echo "<th width=\"8%\" align=left nowrap>".$tmp."</th>";
//Bouton Supprimer
echo "<th width=\"8%\" align=left nowrap>".$tmp."</th></tr>";

};

?>

Ca a l'air correct...

Essaie de me mettre le code HTML de ta page qui contient le formulaire, et fais un

print_r($_POST)

après

for ($j = 0; $j < $nbr_entrees ; $j++)
if ($etat[$j] != "") echo " etat[$j]= $etat[$j] <br>"; 

Et donne le résultat
