How to upload prc file type?

Question

When I try to upload a *.prc file type, I get this error:

Sorry, this file type is not permitted for security reasons.

How can I fix this?

Answer 1

This article explains a method in which you can add a file type to the list of allowed file types.

Copy and paste the following code into your functions.php:

add_filter('upload_mimes', 'custom_upload_mimes');
function custom_upload_mimes ( $existing_mimes=array() ) {
    // add your extension to the array
    $existing_mimes['prc'] = 'application/x-mobipocket-ebook';

    // add as many as you like
    // and return the new full result
    return $existing_mimes;
}

I didn't tested the code, but I hope it will help you along.

Answer 2

Add following code in your themes functions.php file. I have tested the code and its working fine.

// Add the filter
add_filter('upload_mimes', 'custom_upload_mimes');

function custom_upload_mimes ( $existing_mimes=array() ) {

    // Add file extension 'extension' with mime type 'mime/type'
    $existing_mimes['prc'] = 'application/x-mobipocket'; 

    // and return the new full result
    return $existing_mimes; 
}
