Hello everyone !!!
I have a very neat script to download files to the server, the problem is
that it uploads all kind of files, txt, exe, zip,
you name it. I have been trying to add some code but still can't get it to
work. What I would like the script to do is only to allow the jpg, jpeg,
bmp, gif files to be downloaded. Can anyone can give me a hand?
Thanks in Advance, Bob.
This is the script. >>>>>>>>>>>>>>>>>>>>>
<form name="upload" enctype="multipart/form-data" method="post" action="">
<input type="file" name="file" />
<br /><input type="submit" name="submit" value="Upload" />

<?php

if(isset($_POST['submit'])) {

$dir = "files/"; //Upload directory
$error = ""; //Setting a false error
$address = "http://".$_SERVER['HTTP_HOST']."/"; //Getting the web address
$file_name = $_FILES['file']['name']; //Getting the file name
$file_type = $_FILES['file']['type']; //Getting the file type
$file_size = "".$_FILES['file']['size']." bytes"; //Getting the file size
$file_tmp = $_FILES['file']['tmp_name']; //Setting the temporary name
$file_address = $address.$dir.$file_name; //URL of file

if(file_exists($dir.$file_name)) {
$error = "<br />Error: A file with the same name already exists!";
}

else {
@copy ($file_tmp, $dir.$file_name) or ($error="<br />Error: File could not
be copied!");
}

if($error != "") {
echo $error;
}

else {
echo "<br />File successfully uploaded!\n";
echo "<br />Name: ".$file_name."\n";
echo "<br />Size: ".$file_size."\n";
echo "<br />Type: ".$file_type."\n";
echo "<br />URL: ".$file_address."";
}
}
?>
