上传三张图片

Question

我一直在努力使用这段代码。我想同时上传几张图片，但它并没有让我到处都是。我希望允许我的用户为他们的广告列表上传三张图片。感谢您的帮助。

<?php 
if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0 )
$title = clean($_POST['title']);
$description = clean($_POST['description']);
$category = clean($_POST['category']);
$price = clean($_POST['price']);
$name = clean($_POST['name']);
$number = clean($_POST['number']);
$email = clean($_POST['email']);
$subcategory = clean($_POST['subcategory']);
$state = clean($_POST['state']);
$city = clean($_POST['city']);

$imagename = basename($_FILES['userfile']['name']);
// PICTURE UPLOAD SYSTEM
$imagename = basename($_FILES['userfile']['name']);

if(empty($imagename)) {
$error = 1;
echo"<h2 class='error'>Image not found</h2>".$back; }

if($error != 1 && $noimg != 1)
{

$filename = stripslashes($_FILES['userfile']['name']);
$extension = substr(strrchr($filename, '.'), 1);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will not       

 // upload the file,  
 //otherwise we will do more tests
}

   if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") &&   

 ($extension != "gif")) 
    {
    //print error message
        echo "<h2 class='error'> Images Must Be Jpg, Gif, or Png Format!  

 </h2>".$back.'';
        $errors=1;
    }
    else
    {

$time = time();
$newimage = "photos/" . $time . $imagename;
//echo $newimage;
$result = @move_uploaded_file($_FILES['userfile']['tmp_name'], $newimage);
if(empty($result)) {
$error = 1;
echo "<h2 class='error'>".$lang['MOVING_UPLOAD_FILE']."</h2><br/>".$back.""; 
}


$date = date("Y-m-d G:i:s") ; 

$query = "INSERT INTO classifieds (id, title, description, state_id, city_id,  

subcat_id, cat, price, name, number, email, picture, date) VALUES ('', '$title', 

'$description', '$state', '$city', '$subcategory', '$category',  '$price', '$name', 

'$number', '$email', '$newimage', '$date')";

mysql_query($query) or die(mysql_error());
?>
<form action="send.php" method="post" name="form"  enctype="multipart/form-data">

  

再次感谢
