Uploading SQL files to WordPress

As part of my recent search through my SQL archive in my last two posts, I wanted to add the actual SQL files to the post, but WordPress didn’t recognize the file format so it wouldn’t accept it – I kept hitting the error “File Type does not meet security guidelines” ūüôĀ

I’ve since made some changes to the WordPress code which should allow me to attach the files, but have struggled to make it so that my changes won’t get wiped out when I upgrade the blog next time.

The way that I’ve got round this is to make a quick change to the file functions.php within the theme that I’m using. ¬†By adding the code below to the existing PHP that was already in the functions.php file, my blog now allows me to upload text files with different extensions. ¬†This can be extended further (if I need / want to) by adding different extensions and different MIME types to the code:

add_filter('upload_mimes', 'addExtraMimes');
function addExtraMimes($mimes)
  $mimes = array_merge($mimes, array('sql|pkg|pks|pkb|pkh|wft' => 'plain/text'));

  return $mimes;

Hope you find that useful – at least I know where to come back to if I need this on my other blogs!
