Max's File Uploader, Нужна Помощь

[Login 21]

Max's File Uploader, это как бы движек для загрузки файлов на хостинг.

 

Проблема в том что если ты заливаешь 2-рой файл с названием первого, то идет замена 1-вого файла.

Как запретить замену файлов? К примеру что бы писало "файл существует".

 

Вот есть код PHP

<?php

/*************************************************

* Max's File Uploader

*

* Version: 1.0

* Date: 2007-11-26

*

****************************************************/

class maxUpload{

var $uploadLocation;

 

/**

* Constructor to initialize class varaibles

* The uploadLocation will be set to the actual

* working directory

*

* @return maxUpload

*/

function maxUpload(){

$this->uploadLocation = getcwd().DIRECTORY_SEPARATOR . 'file/';

}

 

/**

* This function sets the directory where to upload the file

* In case of Windows server use the form: c:\\temp\\

* In case of Unix server use the form: /tmp/

*

* @param String Directory where to store the files

*/

function setUploadLocation($dir){

$this->uploadLocation = $dir;

}

 

function showUploadForm($msg='',$error=''){

?>

<div id="container">

<div id="header"><div id="header_left"></div>

<div id="header_main">Max's File Uploader</div><div id="header_right"></div></div>

<div id="content">

<?php

if ($msg != ''){

echo '<p class="msg">'.$msg.'</p>';

} else if ($error != ''){

echo '<p class="emsg">'.$error.'</p>';

 

}

?>

<form action="" method="post" enctype="multipart/form-data" >

<center>

<label>File:

<input name="myfile" type="file" size="30" />

</label>

<label>

<input type="submit" name="submitBtn" class="sbtn" value="Upload" />

</label>

</center>

</form>

</div>

<div id="footer"><a href="http://www.phpf1.com" target="_blank">Powered by PHP F1</a></div>

</div>

<?php

}

 

function uploadFile(){

if (!isset($_POST['submitBtn'])){

$this->showUploadForm();

} else {

$msg = '';

$error = '';

 

//Check destination directory

if (!file_exists($this->uploadLocation)){

$error = "The target directory doesn't exists!";

} else if (!is_writeable($this->uploadLocation)) {

$error = "The target directory is not writeable!";

} else {

$target_path = $this->uploadLocation . basename( $_FILES['myfile']['name']);

 

if(@move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {

$msg = basename( $_FILES['myfile']['name']).

" was uploaded successfully!";

} else{

$error = "The upload process failed!";

}

}

 

$this->showUploadForm($msg,$error);

}

 

}

 

}

?>
