Check to see if the uploaded file is a valid format.

[TeroYukio]

I got it able to upload, however I'm trying to restrict what type of files can be uploaded. (I want just .s2z files and .honmod files to be able to be uploaded.)  What should I use to restrict something like that because I tried this:

 

if ($uploaded_type =="text/x-generic") {
echo "Blah Blah Blah<br>";
$ok=0;
}

 

Which did not work.  What do you suggest?

 

<?php

$target = "/*/*/public_html/upload/";

$target = $target . basename( $_FILES['uploaded']['name']) ;

$ok=1;

if ($ok==0) {

echo "Sorry your file was not uploaded";

}else{

if(move_uploaded_file($_FILES['uploaded']['tmp_name'],$target)){

echo "The file <b>".basename( $_FILES['uploaded']['name'])."</b> has been uploaded";

}else{

echo "Sorry, there was a problem uploading your file."; 

}
}

?>

First test with actual extension

 

$extensionorig = end(explode('.', $filename));
if ($extensionorig == 's2z')
{
   $ext = ".s2z";
} 
else if ($extensionorig == 'honmod')
{
   $ext = ".honmod";
} 
else 
{
echo "Invelid File Type. only .honmod, .s2z can be uploaded.";
        flag++;
}

 

Second test by reading  MIME Types

$mimetype = $_FILES['uploadedfile']['type'];
if($mimetype != 'application/x-whatever' || $mimetype != 'application/x-whatever2' )
{
$flag++;
}

 

Third test reading actual file.

 

if ($extensionorig == 'jar')  // For ex. examining a valid jar (Java) file
{
   $f = @fopen($_FILES['uploadedfile']['tmp_name'],'r'); // open the file
   $s = @fread($f,2); // read first two characters. 
   @fclose($f); 
   if($s != "PK"){

   if($flag == 0){
   $error = "<RED>The file you are attempting to upload does not appear to be a valid jar (java) game file.We do not allow you to upload this game.</RED>";
   }
   $flag++;
   }

}

Flag increment here shows error message

Thank you very much.  I'll test all three of these and see which one works and I'll post back here to say if my problem was solved or not!
