i have created a photography website with an admin page that uploads photos to different categories in a mysql table. This much works, but i can only upload one file at a time and i'd like to be able to select multiple images.
Here's the form
<form action="index.php" enctype="multipart/form-data" name="myForm" id="myForm" method="post">
<select name="category" id="category">
<option value="Nature">Nature</option>
<option value="People">People</option>
<option value="Abstract">Abstract</option>
</select>
<input type="file" name="fileField" id="fileField" />
<input type="submit" name="submit" id="submit" value="Add Images" />
</form>
And here's the php for parsing the form
if (isset($_POST['submit'])) {
$category = mysql_real_escape_string($_POST['category']);
// Add this product into the database now
$sql = mysql_query("INSERT INTO images (category, date_added)
VALUES('$category',now())") or die (mysql_error());
$pid = mysql_insert_id();
// Place image in the folder
$newname = "$pid.jpg";
move_uploaded_file( $_FILES['fileField']['tmp_name'], "../photos/$newname");
header("location: thumbnail_generator.php");
exit();
}
I looked into the html5 file input method, and as far as i can tell, i can change the input as folllows:
<input type="file" name="fileField[]" id="fileField" multiple="multiple"/>
This allows me to select multiple files on the site, but i can't figure out how to implement this into my php. Any help would be much appreciated.

return $ext;
}
$errors=0;
if(isset($_POST['sendfiles']))
{
$uploaddir = "files/"; //a directory inside
foreach ($_FILES['photos']['name'] as $name => $value)
{
$filename = stripslashes($_FILES['photos']['name'][$name]);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
echo "\n This is the extension: ",$extension;
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif"))
{
//print error message
?>
<h4>Unknown extension!</h4>
<?php
$errors=1;
}
else
{
$size=filesize($_FILES['photos']['tmp_name'][$name]);
if ($size > MAX_SIZE*1024)
{
?>
<h4>You have exceeded the size limit!</h4>
<?php
$errors=1;
}
$image_name=$filename.'.'.$extension;
$newname="files/".$image_name;
$copied = copy($_FILES['photos']['tmp_name'][$name], $newname);
if (!$copied)
{
?>
<h4>Copy unsuccessfull!</h4>
<?php
$errors=1;
}
}
}
//echo "Images uploaded successfully";
}
//mysql_close($dbhandle);
?>
You are probably looking for something like uploadify or swfupload or plupload.

It works as-if there were multiple file fieldsDocs, it's transparent to PHP. Here is some simple example code:
<html>
<body>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="fileField[]" id="fileField" multiple="multiple">
<input type="text" name="test" value="test">
<input type="submit" name="submit">
</form>
</body>
</html>
<?php
var_dump($_FILES, $_POST);
Store it on your host and request it. You can then play around with it, it will show you the structure of the $_FILES and $_POST array.
Example output:
array
'fileField' =>
array
'name' =>
array
0 => string 'hakre-iterator-fun-cut-top.png' (length=30)
1 => string 'hakre-iterator-fun-cut-middle.png' (length=33)
'type' =>
array
0 => string 'image/png' (length=9)
1 => string 'image/png' (length=9)
'tmp_name' =>
array
0 => string '/tmp/php1A2.tmp' (length=15)
1 => string '/tmp/php1A3.tmp' (length=15)
'error' =>
array
0 => int 0
1 => int 0
'size' =>
array
0 => int 234001
1 => int 213058
array
'test' => string 'test' (length=4)
'submit' => string 'Submit' (length=6)

Simple! Just Add multiple="true" to your input tag.
<input name "example" type="file" multiple="true"/>
