Problem
I’ve done this before with a single file upload using an input type=”file”>. However, I’m having problems uploading multiple files at once.
For example, I’d like to select a group of photographs and upload them all at once to the server.
If at all possible, a single file input control would be ideal.
Does anyone know how to accomplish this?

This is possible in HTML5. Example (PHP 5.4):
<!doctype html>
<html>
<head>
<title>Test</title>
</head>
<body>
<form method="post" enctype="multipart/form-data">
<input type="file" name="my_file[]" multiple>
<input type="submit" value="Upload">
</form>
<?php
if (isset($_FILES['my_file'])) {
$myFile = $_FILES['my_file'];
$fileCount = count($myFile["name"]);
for ($i = 0; $i < $fileCount; $i++) {
?>
<p>File #<?= $i+1 ?>:</p>
<p>
Name: <?= $myFile["name"][$i] ?><br>
Temporary file: <?= $myFile["tmp_name"][$i] ?><br>
Type: <?= $myFile["type"][$i] ?><br>
Size: <?= $myFile["size"][$i] ?><br>
Error: <?= $myFile["error"][$i] ?><br>
</p>
<?php
}
}
?>
</body>
</html>
After selecting two items in the file dialog in Chrome, this is what it looks like:
After hitting the “Upload” button, this is what it looks like.
This is simply a rough draft of a complete solution. For further information on how to handle file uploads properly and securely in PHP, see PHP Manual: Handling File Uploads.

To generate a multiple file upload, you’ll need to perform a few things, which are actually quite simple. Java, Ajax, and Flash are not required. Create a standard file upload form by beginning with:
<form enctype="multipart/form-data" action="post_upload.php" method="POST">
Then the key to success;
multiple />input type=”file” name=”file[]” multiple />input type=”file” name=”file[]” multiple />input type=”file” name
Remember to use brackets! Try the following in post upload.php:
<?php print_r($_FILES['file']['tmp_name']); ?>
You’ll see that you obtain an array with tmp name data, which means you can access each file using the file ‘number’ example with a third pair of brackets:
$_FILES['file']['tmp_name'][0]
To count the number of files that were selected, use the php count() function. Best of luck, widdit!

In Firefox 5, the following is the complete solution:
<html>
<head>
</head>
<body>
<form name="uploader" id="uploader" action="multifile.php" method="POST" enctype="multipart/form-data" >
<input id="infile" name="infile[]" type="file" onBlur="submit();" multiple="true" ></input>
</form>
<?php
echo "No. files uploaded : ".count($_FILES['infile']['name'])."<br>";
$uploadDir = "images/";
for ($i = 0; $i < count($_FILES['infile']['name']); $i++) {
echo "File names : ".$_FILES['infile']['name'][$i]."<br>";
$ext = substr(strrchr($_FILES['infile']['name'][$i], "."), 1);
// generate a random new file name to avoid name conflict
$fPath = md5(rand() * time()) . ".$ext";
echo "File paths : ".$_FILES['infile']['tmp_name'][$i]."<br>";
$result = move_uploaded_file($_FILES['infile']['tmp_name'][$i], $uploadDir . $fPath);
if (strlen($ext) > 0){
echo "Uploaded ". $fPath ." succefully. <br>";
}
}
echo "Upload complete.<br>";
?>
</body>
</html>

You’re mostly out of luck if you wish to select many files from the file selector window that appears when you select browse. You’ll need a Java applet or something similar for this (I think there is one that use a small flash file, I will update if I find it). Currently, a single file input allows only one file to be selected.
If you’re talking about many file inputs, there shouldn’t be much of a difference between using one and using multiple. Please post some code and I will do my best to assist you further.
Update: There is a flash-based approach for using a single ‘browse’ button. I’ve never used it myself, but I’ve heard a lot of good things about it. I believe it is your greatest chance.

To begin, create a form that looks like this:
<form method="post" enctype="multipart/form-data" >
<input type="file" name="file[]" multiple id="file"/>
<input type="submit" name="ok" />
</form>
That’s correct. Now paste this code into your form code or any website you choose.
<?php
if(isset($_POST['ok']))
foreach ($_FILES['file']['name'] as $filename) {
echo $filename.'<br/>';
}
?>
it’s easy… finish
