基本上我的代码是一个图像上传，我怎样才能让一个函数能够上传3张图片。
解决方案
这里是多个上传图片的代码。您可以上传超过3张图片。
 < form action =upload.phpmethod =postenctype =多部分/格式数据> 
< 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 =submitname =submitvalue =Submit/> 
< / form> 
 
  include（'configdb.php'）; 
 
 $ uploadDir ='upload /'; 
 
 if（isset（$ _ POST ['submit']））{
 
 $ image = array（）; 
 $ b foreach（$ _ FILES ['image'] ['name'] as $ index => $ name）{
 
 if（$ _ FILES ['image'] [ 'error'] [$ index] == 4）{
 continue; 
 
 $ b $ if（$ _ FILES ['image'] ['error'] [$ index] == 0）{
 
 $ fileName = $ _FILES [ '图像'] [ '名称'] [$指数]; 
 $ tmpName = $ _FILES ['image'] ['tmp_name'] [$ index]; 
 $ fileSize = $ _FILES ['image'] ['size'] [$ index]; 
 $ fileType = $ _FILES ['image'] ['type'] [$ index];如果（$ fileType ==image / gif|| 
 $ fileType ==image / jpeg|| 
 $ fileType ==image / pjpeg）
 
 || 
 $ fileType ==image / png|| 
 $ fileType ==image / x-png）&& 
 $ fileSize< 500000）{
 
 $ imagePath = $ uploadDir。 $文件名; 
 
 $ result = @move_uploaded_file（$ tmpName，$ imagePath）; 
 if（！$ result）{
 echoError uploadloading; 
出口; 
} 
 $ image [] = $ imagePath; 
 
 
 $ b //将图像保存到数据库
 $ 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：由于安全性的原因，您应该在上传之前测试图片的类型和大小。 / p> 
Hi there I want to make a function for me to able upload a multiple image in one submission below are my code structure:
<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());
  }

}
Basically my code above does one image upload, How can I make a function to be able upload 3 images.
 解决方案 
Here is the code to multiple upload image. You can upload more than 3 images.
<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);
    }
}

?>
Note: you should test the type and the size of image before upload it because of the security.
