Filter Action Hook Problem

  • Hello everyone,

    I’m trying to apply a filter to the post content before it get save to the database that way the filter is only done once.
    I don’t want to use the content filter because it would mean that my filter is applied every time the content is displayed.

    for example:
    add_filter(‘the_content’, ‘FilterFunction’);

    I’ve tried using the action hook “pre_post_update” but it didn’t seem to do anything and the Codex documentation doesn’t exist.

    Any Ideas?
