Problem while doing "insert"

Hello,

I'm using php Version 3.0.12 to interface
with a postgresql sgbd.

When i'm doing this request :

$query = "insert into mailing values ('$champs1', '$champs2', display=$myradio)";
$result = pg_exec($connection,$query);
if (!$result)
echo "<a href=https://dooz.corp.intrinsec.com/mail/insert.php3>Recommencer</a>";
else
echo "<a href=https://dooz.corp.intrinsec.com/mail/essai.php3>Voir la nouvelle base</a>";
echo "<br>";
$close = pg_close($connection);
if ($close == true)
echo ("<b>D&eacute;connection a la base</b><br>");
else
echo ("<b>Aucune connection a fermer</b><br>");

The insert succeed, but it insert 6 or more time
the same entry.

Have i done something wrong ?
