Question

Simple question. Is there a way to only allow txt files upon uploading? I’ve looked around and all I find is text/php, which allows PHP.

$uploaded_type=="text/php

Answer 1

When you upload a file with PHP its stored in the $_FILES array. Within this there is a key called “type” which has the mime type of the file EG $_FILES['file']['type']

So to check it is a txt file you do

if($_FILES['file']['type'] == 'text/plain'){
    //Do stuff with it.
}

It’s explained very well here. Also, don’t rely on file extentions it’s very unreliable.
