Secure File Upload with PHP
HyperSilence.net - Silentum Uploader - PHP Upload Script
Of you can use the script below.
Just save this as something like FileUpload.php
PHP Code:
<?php
class FileUpload {
public $MaxSize = "2MB";
public $AllowedExtensions = "jpeg,jpg,gif,png,bmp,xbm,xpm";
public $UploadDirectory = "./images/";
private $filetemp;
private $filename;
private $filetype;
private $filesize;
private $fileerror;
private $fileextension;
public function __construct($filesArray = null) {
if(isset($filesArray)) {
self::SetFileInfo($filesArray);
}
}
public function SetFileInfo($filesArray) {
if(isset($filesArray) && is_array($filesArray)) {
$this->filetemp = $filesArray['tmp_name'];
$this->filename = $filesArray['name'];
$this->filetype = $filesArray['type'];
$this->filesize = $filesArray['size'];
$this->fileerror = $filesArray['error'];
$this->fileextension = strtolower(array_pop(explode(".", $this->filename)));
}
}
public function Upload($uploadDir = null) {
if(isset($this->filetemp) && isset($this->filename) && $this->fileerror == 0) {
if(empty($uploadDir)) { $uploadDir = $this->UploadDirectory; }
if(!in_array($this->fileextension, explode(",", $this->AllowedExtensions))) {
echo "The file is not of a supported type, allowed types are {$this->AllowedExtensions}";
return false;
}
if($this->filesize > self::ParseSize($this->MaxSize)) {
echo "File is too large, the max size is {$this->MaxSize}";
return false;
}
if(is_uploaded_file($this->filetemp)) {
if(move_uploaded_file($this->filetemp, $uploadDir . $this->filename)) {
if(file_exists($uploadDir . $this->filename)) {
echo "Your file has been uploaded";
return true;
}
}
}
}
return false;
}
private function ParseSize($size) {
preg_match("(([0-9]+)([a-zA-Z]+))", $size, $match);
$multiplier = 1;
if(is_string($match[2])) {
switch(strtolower($match[2])) {
case "b":
$multiplier = 1;
break;
case "kb":
$multiplier = 1024;
break;
case "mb":
$multiplier = (1024 * 1024);
break;
case "gb":
$multiplier = ((1024 * 1024) * 1024);
break;
default:
$multiplier = 1;
break;
}
if(is_integer((int)$match[1])) {
return $match[1] * $multiplier;
}
}
return false;
}
}
?>
Then use this to upload files.
Don't forget to change "/path/to/uploadfile.php" to point to
whatever you saved the above script as.
PHP Code:
<form action="<?php $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
<div>
<label>File</label>
<input type="file" name="myFile" size="30" /><br /><br />
<input type="submit" name="upload" value="Upload" />
</div>
</form>
<?php
if(isset($_POST['upload'])) {
include "/path/to/uploadfile.php";
$upload = new FileUpload($_FILES['myFile']);
$upload->Upload("images/");
}
?>
