我目前有一个用户上传选项，它将上传到一个文件夹，并用文件名更新数据库，然后稍后检索。
我希望能够进行多次上传，每个上传的文件都会进入他们选择并上传的上传字段的特定列中。
3个浏览部分（上传选项），1个是徽章照片，2个是驾驶执照，3个是社会保障卡。
如果可能的话，将每个文件上传到它们自己指定的文件夹位置。
我还想限制除图像类型、PDF或文档文件外的所有文件。
我目前有以下内容。
if(isset($_POST['btn-upload']))
{
$file = rand(1000,100000)."-".$_FILES['file']['name'];
$file_loc = $_FILES['file']['tmp_name'];
$file_size = $_FILES['file']['size'];
$file_type = $_FILES['file']['type'];
$folder="badge/";
// new file size in KB
$new_size = $file_size/1024;
// new file size in KB
// make file name in lower case
$new_file_name = strtolower($file);
// make file name in lower case
$final_file=str_replace(' ',$FirstName,$new_file_name);
if(move_uploaded_file($file_loc,$folder.$final_file))
{
$sql="UPDATE users t1 SET t1.badgephoto='$final_file', t1.badgetype='$file_type', t1.badgesize='$new_size' WHERE t1.API='$API'";
mysql_query($sql);
?>
<script>
alert('successfully uploaded');
window.location.href='badgephoto.php?success';
</script>
<?php
}
else
{
?>
<script>
alert('error while uploading file');
window.location.href='badgephoto.php?fail';
</script>
<?php
}
}
HTML
<form action="badgephoto.php" method="post" enctype="multipart/form-data">
<input type="file" name="file" accept="application/msword, text/plain, application/pdf, image/*" /> <!-- would be badgephoto -->
<input type="file" name="file_drivers" accept="application/msword, text/plain, application/pdf, image/*" />
<input type="file" name="file_social" accept="application/msword, text/plain, application/pdf, image/*" />
<button type="submit" name="btn-upload">Upload Badge Photo</button>
</form>
如有任何帮助，我们将不胜感激。
