Hướng dẫn Custom Formatters rất dễ cho Drupal Embeds

Many websites want to allow users to submit videos, audio files, documents and the like.

However, if those files are stored on other sites, it can be difficult to display that content consistently. For example, if you allow people to submit YouTube videos, there are multiple different types of embed code.

One of our members wanted to allow users to submit Google docs that would automatically be shown inside iframes.

The solution to all these problems is the "Custom Formatters" module. Here's how to use Custom Formatters:

• Click Tokens.
• Choose the field that you created earlier:

• Click Save.

• Go to Structure > Content types > Manage Display.
• Apply your new format to the Google Docs ID field:

Using the Custom Formatter

• Go to add a new Document to your site.
• Enter the Google Doc ID as shown:

• When you publish the content, the Google Doc ID will be automatically be converted into an iframe embed:

This technique should work for many other sites such as YouTube, Vimeo or Flickr. You can control the embed and just ask users to enter the unique ID.
