The file you attempted to upload is not allowed.
Here is my PHP Script:
<?php
if(!isset($_COOKIE['loggedin'])){
header("location:user_login.php");
}
session_start();
if(!isset($_SESSION['user'])){
header("location: user_login.php");
}
else {
?>
<?php
include("connection.php");
$current_page_URL =(isset($_SERVER["HTTPS"]) && $_SERVER["HTTPS"]==”on”) ? “https://” : “http://”;
$current_page_URL = $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
$allowed_filetypes = array('.avi','.mp4','.wmv','.flv');
$max_filesize = 104857660;
$upload_path = 'uploads/';
$filename = $_FILES['file']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);
if(!in_array($ext,$allowed_filetypes))
die('The file you attempted to upload is not allowed.');
function bytesToSize1024($bytes, $precision = 2) {
$unit = array('B','KB','MB');
return #round($bytes / pow(1024, ($i = floor(log($bytes, 1024)))), $precision).' '.$unit[$i];
}
$sFileName = $_FILES['file']['name'];
$sFileType = $_FILES['file']['type'];
$sFileSize = bytesToSize1024($_FILES['file']['size'], 1);
if (file_exists("uploads/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"uploads/" . $_FILES["file"]["name"]);
echo "Stored in: ".$_SERVER["SERVER_NAME"]. "/uploads/" . $_FILES["file"]["name"];
}
$savefile = $_SERVER["SERVER_NAME"]. "/uploads/" . $_FILES["file"]["name"];
$insert_query = "insert into save_data (username, Name, Type, size, link) values ('".$_SESSION['user']."','$sFileName','$sFileType','$sFileSize','$savefile')";
if(mysql_query($insert_query)){
echo "<script>alert('Successfully added to DB')</script>";
}}
?>

Answer 1

Check the extension of the file being uploaded.
So,simply do
echo $ext;
See if it matches the values in the array. Chances are it doesn't.
Hope this helps.
