Change which type of files you can upload in WordPress

We recently had a client that needed to be able to upload a “vCard” and they were not able to do so. That is because WP limits what type of files can be uploaded. By default you can only upload media to the “Media Library”, which makes perfect sense, right? But what if we need to upload PowerPoint, Word documents, etc, well, here is the code that allows you to do that.

Go to the theme’s functions.php file and drop in the code (within the tags that should already be at the top of the file).
[cc lang=”html”]
add_filter(‘upload_mimes’, ‘custom_upload_mimes’);
function custom_upload_mimes ( $existing_mimes=array() ) {
$existing_mimes[‘vcard’] = ‘application/x-vcard’;
$existing_mimes[‘vcf’] = ‘application/x-vcf’;
return $existing_mimes;
}
[/cc]
