Wordpress Allow Custom Font Upload

custom-fonts.php

<?php
  // add to your theme's functions.php file
  add_filter('upload_mimes', 'add_custom_upload_mimes');
  function add_custom_upload_mimes($existing_mimes) {
  	$existing_mimes['otf'] = 'application/x-font-otf';
  	$existing_mimes['woff'] = 'application/x-font-woff';
  	$existing_mimes['ttf'] = 'application/x-font-ttf';
  	$existing_mimes['svg'] = 'image/svg+xml';
  	$existing_mimes['eot'] = 'application/vnd.ms-fontobject';
  	return $existing_mimes;
  }
?>

Great. worked out

doesn't work for otf :(

neither does ttf for some reason... the function is being called and the ttf is in list

perfect

not working for .ttf

not working for .ttf

for ttf it depends of your server. You can get it like this :

mime_content_type ( 'path/to/some/file.ttf' );

or even

$existing_mimes['ttf'] =  mime_content_type ( get_stylesheet_directory().'/src/fonts/examplefont.ttf' );

Just wanna say thank you...
It works for me.

@olivierstern awesome, on my current host it was "application/font-sfnt" !
