Multi upload
Hej, jeg har et script til at uploade billeder med, men det kan kun uploade 1 billede af gangen.Håber der en der kan hjælpe mig med det.
Det ser sådan ud:
<?
// get variables for fields on upload screen
$thefile = $_FILES['thefile'];
$tos = $_POST['tos'];
$currentip = $_SERVER['REMOTE_ADDR'];
$messages = "";
// check for blocked ip address

$link = mysql_connect($db_server, $db_user, $db_password) or die("Could not connect to the database.");
mysql_select_db($db_name) or die("Could not select the database.");
$query = "select ip from blocked where ip = '$currentip'";
$result = mysql_query($query) or die("Query failed.");
$num_rows = mysql_num_rows($result);
if ($num_rows > 0) {
$messages .= "Din IP adresse (" . $currentip . ") er blevet blokeret for denne service.<br><br>";
}
}
// check for a file
if (!isset($thefile) || $thefile['name'] == "") {
$messages .= "Du skal vælge et billede der skal uploades.<br><br></a>";
}
// check to see if tos was read
if ($tos == "") {
$messages .= "Du skal acceptere vores vilkår for at bruge denne service.<br><br>";
}
if ($messages == "") {
// check for valid file type

}
// check for valid file extension
