How to display content in a textarea in a node view result on a Drupal 7 site?

Question

i'm a newbie drupal user and i want to use a hook to display some content for a specific node type. I have a video portal where i use video module of Drupal. I want to display a textarea zone with embed code for my visitors to share the content on their blogs or sites (like youtube or vimeo etc...). I think i need to write a little module to do that but which hook i need to use to do this action ?

Thanks for your help

If it's something you'll be reusing a lot (on this project or in the future) I'd personally build a custom formatter for it. Custom formats will appear in a fields display settings so if you build a custom formatter module called share_code you can just select 'share code' from the display list and it will render it accordingly.

There is a good tutorial on how to build a Facebook link custom formatter here - http://www.metaltoad.com/blog/drupal-7-tutorial-creating-custom-formatters

I've used this to build a Youtube video formatter and Twitter links.

You handle the output using hook_field_formatter_view. So just amend the tutorial above to output the fields value in an un-editable text area.
