php的多重上传图片功能？

您好，我想为我创建一个功能，以便能够在一次提交中上传多个图像，下面是我的代码结构：

<form action="upload.php" method="post" enctype="multipart/form-data">
  <p>Image1 :<input name="image1" type="file" /></p>
  <p>Image2 :<input name="image2" type="file" /></p>
  <p>Image3 :<input name="image3" type="file" /></p>
  <input type="submit" value="Submit" />
</form>

include('configdb.php');

$uploadDir = 'upload/';

if(isset($_POST['submit']))
{
$fileName = $_FILES['image1']['name'];
$tmpName  = $_FILES['image1']['tmp_name'];
$fileSize = $_FILES['image1']['size'];
$fileType = $_FILES['image1']['type'];

$image1path = $uploadDir . $fileName;


$result = move_uploaded_file($tmpName, "$image1path");
if (!$result) {
echo "Error uploading";
exit;
}

if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
    $image1 = addslashes($image1path);
}



$sql="INSERT INTO picture (image1, image2, image3) VALUES ('$image1','$image2', $image3)";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }

}

基本上我上面的代码只上传一张图片，我怎样才能制作一个能够上传 3 张图片的函数。

这是多张上传图像的代码。您可以上传 3 张以上的图片。

<form action="upload.php" method="post" enctype="multipart/form-data">
  <p>Image1 :<input name="image[]" type="file" /></p>
  <p>Image2 :<input name="image[]" type="file" /></p>
  <p>Image3 :<input name="image[]" type="file" /></p>
  <input type="submit" name="submit" value="Submit" />
</form>

<?php
include('configdb.php');

$uploadDir = 'upload/';

if(isset($_POST['submit'])) {

    $image = array();

    foreach($_FILES['image']['name'] as $index => $name) {

        if($_FILES['image']['error'][$index] == 4) {
            continue;
        }

        if($_FILES['image']['error'][$index] == 0) {

            $fileName = $_FILES['image']['name'][$index];
            $tmpName  = $_FILES['image']['tmp_name'][$index];
            $fileSize = $_FILES['image']['size'][$index];
            $fileType = $_FILES['image']['type'][$index];

            if(($fileType == "image/gif"   ||
                $fileType == "image/jpeg"  ||
                $fileType == "image/pjpeg" ||
                $fileType == "image/png"   ||
                $fileType == "image/x-png") && 
                $fileSize < 500000) {

                $imagePath = $uploadDir . $fileName;

                $result = @move_uploaded_file($tmpName, $imagePath);
                if (!$result) {
                    echo "Error uploading";
                    exit;
                }
                $image[] = $imagePath;
            }
        }
    }
    // Save images to database
    $nbImage = count($image);
    if($nbImage) {

        $sql = "INSERT INTO picture (image1, image2, image3) VALUES (";
        for($i=0; $i<$nbImage; $i++) {
            if($i) $sql .= ",";
            $sql .= "\"".$image[$i]."\"";
        }
        $sql .= ")";

        @mysql_query($sql);
    }
}

?>

注意：出于安全考虑，您应该在上传图片之前测试图片的类型和大小。
