我尝试集成http://plugins.krajee.com/file-input/demo的文件输入插件。
下面是我的简单形式：

<form action="process.php" method="post" enctype="multipart/form-data">
<input id="krajee" type="file" name="file[]" multiple="true">
<input type="submit" name="submit" id="submit">
</form>

这允许我浏览和选择多个文件。当我提交表单时，它将所有文件上载到我的服务器。但是，当我浏览选择文件1，然后浏览选择另一个文件（文件2）时。它还显示2个文件预览，但当我提交表单时，它只上载最后选择的文件。请帮助...谢谢
下面是我的process.php文件：

<?php
if(isset($_POST["submit"])){
require("../configs/dbconnect.php");
/*Form variable   */
$owner = mysql_real_escape_string($_POST["owner"]);
$title = mysql_real_escape_string($_POST["title"]);
$description = mysql_real_escape_string($_POST["description"]);
$city = mysql_real_escape_string($_POST["city"]);
$brand = mysql_real_escape_string($_POST["brand"]);
$marketprice = mysql_real_escape_string($_POST["marketprice"]);
$price = mysql_real_escape_string($_POST["price"]);
$phone = mysql_real_escape_string($_POST["phone"]);

    {
        // check if there is a file in the array
        if(!is_uploaded_file($_FILES['file']['tmp_name'][$i]))
        {
            $messages[] = 'No file uploaded';
        }
        /*** check if the file is less then the max php.ini size ***/
        //elseif($_FILES['image']['size'][$i] > $upload_max)
        //{
        //    $messages[] = "File size exceeds $upload_max php.ini limit";
        //}
        // check the file is less than the maximum file size
        elseif($_FILES['file']['size'][$i] > $max_file_size)
        {
            $messages[] = "File size exceeds $max_file_size limit";
        }
        else
        {

            // copy the file to the specified dir 
            if(move_uploaded_file($_FILES['file']['tmp_name'][$i],$upload_dir.'/'.$name[$i]))
            {
                /*** give praise and thanks to the php gods ***/
                $messages[] = $name[$i].' uploaded';
                $image_path[$i]=$upload_dir.'/'.$name[$i];
            }
            else
            {

}
$image_path_string=serialize($image_path);
$sql = "INSERT INTO memberpost(owner, title, description, city, brand, marketprice, price, phone, image) VALUES ('$owner', '$title','$description','$city','$brand','$marketprice','$price','$phone', '" . $image_path_string . "')";
$result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error());
 if(sizeof($messages) != 0)
{
    foreach($messages as $err)
    {
        echo $err.'<br />';
    }
}
}
