Errores comunes
I've made a function to upload many files at once, you can give an array, or send an alone file.
Change the array with the extensions you want.
<?php
// Andrés Ortiz
function UploadFiles($files,$folder){
$extperms = array('gif','jpg','png');
if(is_array($files)){
for($i=0;$i<count($files['error']);$i++){
if($files['error'][$i] == 0){
$tmpname = $files['tmp_name'][$i];
$ext = strtolower(substr($files['name'][$i], -3, 3));
$filename = $files['name'][$i];
if(in_array($ext, $extperms)){
$endpath[$i] = $folder . $files['name'][$i];
if(!@move_uploaded_file($files['tmp_name'][$i], $endpath[$i])){
$logger['UploadFiles'][] = 'Couldn\'t upload the file, try again later';
}
else{
if(!@chmod($endpath[$i], 0777)){
$logger['UploadFiles'][] = 'Couldn\'t change permissions file, ignoring...';
}
}
$weigth[$i] = ($tam = @stat($endpath[$i]))?$tam[7]:$endpath[$i];
}
else{
$logger['UploadFiles'][] = 'You must upload files with image extensions (JPG, PNG, GIF)';
}
}
else{
$logger['UploadFiles'][] = 'The files have errors, check first and then try again';
return false; // If you don't want what the others uploads die, comment this.
}
}
return array('files' => $endpath, 'stat' => $weigth);
}
else{
if($files['error'] == 0){
$tmpname = $files['tmp_name'];
$ext = strtolower(substr($files['name'], -3, 3));
$filename = $files['name'];
if(in_array($ext, $extperms)){
$endpath = $folder . $files['name'];
if(!@move_uploaded_file($files['tmp_name'], $endpath)){
$logger['UploadFiles'][] = 'Couldn\'t upload the file, try again later';
}
else{
if(!@chmod($endpath, 0777)){
$logger['UploadFiles'][] = 'Couldn\'t change permissions file, ignoring...';
}
}
$weigth = ($tam = @stat($endpath))?$tam[7]:$endpath[$i];
}
else{
$logger['UploadFiles'][] = 'You must upload files with image extensions (JPG, PNG, GIF)';
}
}
else{
$logger['UploadFiles'][] = 'The files have errors, check first and then try again';
return false;
}
return array('files' => $endpath, 'stat' => $weigth);
}
if(count($logger['UploadFiles'])>0){
echo '<pre><br /> <b>Some Errors were found.</b><hr /><br />';
print_r($logger);
echo '</pre>';
}
}

UploadFiles($_FILES,'uploads/files/');

Envío de multiples ficheros
Se pueden enviar multiples ficheros usando diferentes nombres (name) para los input.
Así mismo, es posible enviar varios archivos simultaneamente y tener organizada en arrays la información. Para hacer esto, se utiliza la misma sintáxis que cuando tenemos multiples "selects" o "checkboxes" en el formulario HTML:
Note: El soporte para envío multiple de ficheros fue añadido en la versión 3.0.10.
Example#1 Envío de multiples ficheros
<form action="file-upload.php" method="post" enctype="multipart/form-data"> Send these files:<br> <input name="userfile[]" type="file"><br> <input name="userfile[]" type="file"><br> <input type="submit" value="Send files"> </form>
Cuando el formulario del ejemplo es enviado, los arrays $HTTP_POST_FILES['userfile'], $HTTP_POST_FILES['userfile']['name'] y $HTTP_POST_FILES['userfile']['size'] son inicializados. Así mismo pasa con $_FILES en PHP 4.1.0 o superiores y $HTTP_POST_VARS en PHP 3. Cuando register_globals esta activa, las variables globales para los archivos recibidos también son inicializadas. Cada uno de estos arrays tendrá en los índices numericos correspondientes los valores para cada fichero recibido.
Por ejemplo, si tomamos como nombres de archivo enviados /home/test/review.html y /home/test/xwp.out. Tendríamos en $HTTP_POST_FILES['userfile']['name'][0] el valor de review.html, y en $HTTP_POST_FILES['userfile']['name'][1] tendríamos xwp.out; analogamente, $HTTP_POST_FILES['userfile']['size'][0] contendría el tamaño del fichero review.html, y asi sucesivamente...
$HTTP_POST_FILES['userfile']['name'][0], $HTTP_POST_FILES['userfile']['tmp_name'][0], $HTTP_POST_FILES['userfile']['size'][0] y $HTTP_POST_FILES['userfile']['type'][0] tambien son asignadas.

With multiple file uploads
post_max_size: the total amount of data posted by the client (all files, and all other form field)
upload_max_filesize: the maximum size of 1 single file. (just like <input type="hidden" name="MAX_FILE_SIZE" value="..."/>)
so, with the directives:
post_max_size 25M
upload_max_filesize 2M
you can send 12 files of up to 2 MB and use up to 1 MB for your additional form-values.
As long as you read only a single copy of 1 file into memory, the memory_limit directive can be held reasonable small as well.

I noticed that the manual does not have a basic processing script for testing purposes to process multiple file uploads. It took me about an hour to figure this out so I figured it should help some newbie.
Also on windows, the OS does not care if you use backslashes and front slashes while writing up a directory path. So for compatibility with *nix just keep it as a foward slash.
(Tested with php5, php4, apache 1.3x and 2x, on winxp pro, win2k pro and win98se and freebsd.)
The script is kept simple for illustration purposes. Dont use it in a production environment.
The form
<form method="post" action="" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="500000">
<?
for($i = 1; $i <= $_POST[totalfiles]; $i++) { echo $i.'. <input type="file" name="photos[]"><br>'."\n"; }
?>
<input type="submit" name="sendfiles" value="Send Files"></form>
The processing script, for simplicities sake in the same file.
if ($_POST[sendfiles]) {
print_r($_POST); echo '<pre>'; print_r($_FILES); echo '</pre>';
$uploaddir = getcwd().'/photos/; //a directory inside
foreach ($_FILES[photos][name] as $key => $value) {
$uploadfile = $uploaddir . basename($_FILES[photos][name][$key]);
//echo $uploadfile;
if (move_uploaded_file($_FILES['photos']['tmp_name'][$key], $uploadfile)) { echo $value . ' uploaded<br>'; }
}
}

Here is a the simple test form I needed, pieced togther from 2 or 3 posts in the documentation elsewhere.
<html>
<head>
<title>HTML Form for uploading image to server</title>
</head>
<body>
<form action="" method="post" enctype="multipart/form-data">
<p>Pictures:
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="submit" value="Send" />
</p>
</form>
<?php
//places files into same dir as form resides
foreach ($_FILES["pictures"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
echo"$error_codes[$error]";
move_uploaded_file(
$_FILES["pictures"]["tmp_name"][$key],
$_FILES["pictures"]["name"][$key]
) or die("Problems with upload");
}
}
?>
</body>
</html>

re: phpuser's comment
I found that if instead of the form structure at the top of the page use one like this:
<form action="file-upload.php" method="post" enctype="multipart/form-data">
Send these files:<br />
<input name="userfile1" type="file" /><br />
<input name="userfile2" type="file" /><br />
<input type="submit" value="Send files" />
</form>
Notice the names are unique and not an array element. Now the array is structured more like phpuser would like. I did this and used...
foreach ($_FILES as $file) { ... }
without issue.

Re: phpuser_at_gmail's comment, a simpler way to have create that data structure is to name your HTML file inputs different names. If you want to upload multiple files, use:
<input type=file name=file1>
<input type=file name=file2>
<input type=file name=file3>
etc...
Each field name will be a key in the $_FILES array.

Elaboration on phpuser at gmail dot com reArrayFiles() function (which assumed sequential, integer keys and uni-dimensional), this function will work regardless of key and key depth:
<?php
// information grouper
function groupFileInfoByVariable(&$top, $info, $attr) {
if (is_array($info)) {
foreach ($info as $var => $val) {
if (is_array($val)) {
groupFileInfoByVariable($top[$var], $val, $attr);
} else {
$top[$var][$attr] = $val;
}
}
} else {
$top[$attr] = $info;
}
return true;
}
// usage
$newOrdering = array ();
foreach ($_FILES as $var => $info) {
foreach (array_keys($info) as $attr) {
groupFileInfoByVariable($newOrdering, $info[$attr], $attr);
}
}
// $newOrdering holds the updated order
?>

When uploading multiple files, the $_FILES variable is created in the form:
Array
(
[name] => Array
(
[0] => foo.txt
[1] => bar.txt
)
[type] => Array
(
[0] => text/plain
[1] => text/plain
)
[tmp_name] => Array
(
[0] => /tmp/phpYzdqkD
[1] => /tmp/phpeEwEWG
)
[error] => Array
(
[0] => 0
[1] => 0
)
[size] => Array
(
[0] => 123
[1] => 456
)
)
I found it made for a little cleaner code if I had the uploaded files array in the form
Array
(
[0] => Array
(
[name] => foo.txt
[type] => text/plain
[tmp_name] => /tmp/phpYzdqkD
[error] => 0
[size] => 123
)
[1] => Array
(
[name] => bar.txt
[type] => text/plain
[tmp_name] => /tmp/phpeEwEWG
[error] => 0
[size] => 456
)
)
I wrote a quick function that would convert the $_FILES array to the cleaner (IMHO) array.
<?php
function reArrayFiles(&$file_post) {
$file_ary = array();
$file_count = count($file_post['name']);
$file_keys = array_keys($file_post);
for ($i=0; $i<$file_count; $i++) {
foreach ($file_keys as $key) {
$file_ary[$i][$key] = $file_post[$key][$i];
}
}
return $file_ary;
}
?>
Now I can do the following:
<?php
if ($_FILES['upload']) {
$file_ary = reArrayFiles($_FILES['ufile']);
foreach ($file_ary as $file) {
print 'File Name: ' . $file['name'];
print 'File Type: ' . $file['type'];
print 'File Size: ' . $file['size'];
}
}
?>
