Well I'm just trying to make it so only files with the extension ".pk3" can be uploaded and it uploads it to the selected radio button..

 

But I don't think ".pk3" has a MIME type soo I need to know how to physically check the file extension before it gets uploaded and only allow .pk3.

 

 

I saw that w2box has this ability but idk how. :/

I use this... That way you can define as many extensions as you like...

 

$pattern="(\.csv$)|(\.CSV$)|(\.xls$)|(\.XLS$)";
$files = array();
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle)))	{
if(eregi($pattern, $file))
###################################

###################################
}
closedir($handle);
}

$path = pathinfo('somerandomfilename.pk3');
echo $path['extension'];

 

Huh???

Then you need to use javascript. But to implement it into the above:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Free ET File Redirect</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>

<body>
<?php
if(isset($_POST['submit'])) {
$url = $_POST['location'];
$pathinfo = pathinfo($_FILES["file"]["name"]);
if (($pathinfo['extension'] == "pk3")
&&($_FILES["file"]["size"] < 52428800))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "File Name: " . $_FILES["file"]["name"] . "<br />";

    if (file_exists("$url" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {



  






  move_uploaded_file($_FILES["file"]["tmp_name"],
      "$url/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "../uploaded/" . $_FILES["file"]["name"];
      }
    }
}
else
{
echo "Invalid file";
}
}
?>

Thanks, that works almost perfectly..

 

Now it doesn't check if it already exists...

 

 

(Oh and if someone wants to work on it, I updated it a tiny bit..)
