I want to disable certain file types from upload from dokan description field

Question

I am using WooCommerce & dokan as multivendor plugin. Sadly, by default Dokan don’t have the option to add Media files in product description like in WooCommerce.

It looks like this:

I found a way to add “Add Media” option that exists in the normal WooCommerce description editor to here as well using this code:

add_action(‘dokan_product_short_description’, ‘add_demo_description’);
function add_demo_description(){
   update_post_meta( get_the_ID(), '_desc', 'Lorem ipsum text' );
}

Now it looks like this:

It actually works, I can add media library items and upload new ones through the Dokan vendor dashboard, and they also appear on the product page description, which is exactly what I need.

Look on product page:

So now that users can add their Media in product description, I understood there is a new problem. the problem is that they can upload any file type here, which is not good because I don’t want people uploading weird stuff to the product description, the only relevant file in my case is MP3, That’s the only file type I want people to be able to insert into the product description.

It's also important to be able to limit file size and file amount, so trolls & bots won't be able to upload 10k files at 10gb each and destroy my server.

Any idea what I can do to ensure people can’t insert anything other than MP3 to the product description?

P.S: If you know of ways to style / change that default mp3 media player to something better that would be great.

Thank you!

Answer 1

The code you have added has an undefined constant which might create an issue with the latest PHP versions. Instead, you may use the code given below which will allow you to add media to the short description and description.

add_filter('dokan_product_short_description', 'add_media_button');
add_filter('dokan_product_description', 'add_media_button');

function add_media_button(){
  return array(
    'media_buttons' => true
  );
}

After adding these codes, you shall see the add media button on your vendor dashboard product short and long description fields.

Now, to remove the file type and size upload problem, you may use a third-party plugin rather than using a hard code. You can also restrict file type and size upload by user roles. I would suggest using WP Upload Restriction plugin. With this plugin, you can limit upload size and type. Though this is not tested by me since it’s a third-party plugin but it should work.

To change the default media player style, you may take the help of this article: https://www.cssigniter.com/css-style-guide-for-the-default-wordpress-media-player/

Hope this helps.
