Tip: For <input type="file"> : To select multiple files, hold down the CTRL or SHIFT key while selecting.
In PHP, it is possible to upload multiple files using a single input file element. You just need to customize your single file upload PHP code and enable your file element to select multiple files.
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>
Here's what it looks like in Chrome after selecting 2 items in the file dialog:
And here's what it looks like after clicking the "Upload" button.
This is just a sketch of a fully working answer. See PHP Manual: Handling file uploads for more information on proper, secure handling of file uploads in PHP.
There are a few things you need to do to create a multiple file upload, its pretty basic actually. You don't need to use Java, Ajax, Flash. Just build a normal file upload form starting off with:
<form enctype="multipart/form-data" action="post_upload.php" method="POST">
Then the key to success;
<input type="file" name="file[]" multiple />
do NOT forget those brackets! In the post_upload.php try the following:
<?php print_r($_FILES['file']['tmp_name']); ?>
Notice you get an array with tmp_name data, which will mean you can access each file with an third pair of brackets with the file 'number' example:
$_FILES['file']['tmp_name'][0]
You can use php count() to count the number of files that was selected. Goodluck widdit!
Full solution in Firefox 5:
<html>
<head>
</head>
<body>
<form name="uploader" id="uploader" action="multifile.php" method="POST" enctype="multipart/form-data" >
<input id="infile" name="infile[]" type="file" onBlur="submit();" multiple="true" ></input>
</form>
<?php
echo "No. files uploaded : ".count($_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>
If you want to select multiple files from the file selector dialog that displays when you select browse then you are mostly out of luck. You will need to use a Java applet or something similar (I think there is one that use a small flash file, I will update if I find it). Currently a single file input only allows the selection of a single file.
If you are talking about using multiple file inputs then there shouldn't be much difference from using one. Post some code and I will try to help further.
Update: There is one method to use a single 'browse' button that uses flash. I have never personally used this but I have read a fair amount about it. I think its your best shot.

in the first you should make form like this :
<form method="post" enctype="multipart/form-data" >
<input type="file" name="file[]" multiple id="file"/>
<input type="submit" name="ok" />
</form>
that is right . now add this code under your form code or on the any page you like
<?php
if(isset($_POST['ok']))
foreach ($_FILES['file']['name'] as $filename) {
echo $filename.'<br/>';
}
?>
it's easy... finish
<form action="" method="POST" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="file[]" multiple/>
<input type="submit" name="submit" value="Upload Image" />
</form>
Using FOR Loop
<?php
$file_dir = "uploads";
if (isset($_POST["submit"])) {
for ($x = 0; $x < count($_FILES['file']['name']); $x++) {
$file_name = $_FILES['file']['name'][$x];
$file_tmp = $_FILES['file']['tmp_name'][$x];
/* location file save */
$file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name; /* DIRECTORY_SEPARATOR = / or \ */
if (move_uploaded_file($file_tmp, $file_target)) {
echo "{$file_name} has been uploaded. <br />";
} else {
echo "Sorry, there was an error uploading {$file_name}.";
}
}
}
?>
Using FOREACH Loop
<?php
$file_dir = "uploads";
if (isset($_POST["submit"])) {
foreach ($_FILES['file']['name'] as $key => $value) {
$file_name = $_FILES['file']['name'][$key];
$file_tmp = $_FILES['file']['tmp_name'][$key];
/* location file save */
$file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name; /* DIRECTORY_SEPARATOR = / or \ */
if (move_uploaded_file($file_tmp, $file_target)) {
echo "{$file_name} has been uploaded. <br />";
} else {
echo "Sorry, there was an error uploading {$file_name}.";
}
}
}
?>
