Upload File Restrictions

[mickolasjae]

I've been trying to set some restrictions on what kinds of files can be uploaded. Such as: file type and file size. I am pretty new to PHP and have exhausted all my efforts.  I have been able to restrict it to just jpegs and gifs successfully but for some reason when I try to add an operator in there to let txt files upload or some other file type I'm unable to. Any help would be great.

 

<?php

$target_path = "uploads_tmp/";

$continue = "upload.html";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);




if($_FILES["uploadedfile"]["type"] == ("image/jpeg")
|| ($_FILES["uploadedfile"]["type"] == ("image/gif")

{
    move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path);
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
    " has been uploaded"; }



else{

echo "The file must be a jpeg or gif";

} 

?>
