Multiple uploads with a single selection. I modified a single upload script to allow for as many as twenty uploads in one batch, with one selection. Not all browsers support this so have a backup upload. Twenty uploads is the php default and the combined size can't exceed the maximum file size.
PHP Code:
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="content-type">
<script type="text/javascript">
//Alerts to errors.
window.onerror=function(msg, url, linenumber){var logerror='Error message: ' + msg + '. Url: ' + url + 'Line Number: ' + linenumber;alert(logerror);return false}
</script>
<body >
<?php
//include("./colors.php");
if(isset($_POST['MAX_FILE_SIZE'])){
$newdir = $_POST['newdir'];
$dir = './Uploads/';
$upload = $dir.$newdir;
if (!file_exists($upload)) {mkdir ($upload); chmod($upload, 0777); }
$uploaddir = $upload."/";
$isAllowed = array("image/jpeg","image/png","image/gif","image/bmp","application/octet-stream");
for ( $f = 0 ; $f < count($_FILES['userfile']['tmp_name']) ; $f++ )
{ $ext = basename($_FILES['userfile']['type'][$f]);
if (move_uploaded_file($_FILES['userfile']['tmp_name'][$f], $uploaddir.$_FILES['userfile']['name'][$f])) {
if (in_array ( $_FILES['userfile']['type'][$f] , $isAllowed )) echo "File ".$_FILES['userfile']['name'][$f]." is valid, and was successfully uploaded.\n<br>";}
if (!in_array ( $_FILES['userfile']['type'][$f] , $isAllowed )){echo "File ".$_FILES['userfile']['name'][$f]." was not an allowed type.\n<br>Allowed types are jpeg, png, gif and bmp\n<br>";}
$img[$f] = $uploaddir.$_FILES['userfile']['name'][$f];
print "<img src=\"".$img[$f]."\"><br>";
}}
echo '<pre>';
print_r($_FILES);
echo "<br>";
print "</pre>";
?>
