Answer 1

try this code:

REPLACE

$().ready(function() {
 $( "#tags" ).autocomplete("consultation/commande_tags.php", {
    width: 108,
    matchContains: true,
    //mustMatch: true,
    //minChars: 0,
    //multiple: true,
    //highlight: false,
    //multipleSeparator: ",",
    selectFirst: false
});
});

CONNECTION :

<?php
$host="localhost";
$user="root";
$pass="";
$bdd="paralel";

// connexion
$con = mysql_connect($host,$user,$pass)or die(mysql_error());

//selection bdd

$db = mysql_select_db($bdd,$con)or die(mysql_error());

?>
