Detailed information

content::item::content_is_null (public)

 content::item::content_is_null revision_id

Determines if the content for the revision is null (not mereley zero-length)

Parameters:
revision_id - The revision id

Returns:
1 if the content is null, 0 otherwise

Testcases:
content_item

content::item::content_methods_by_type (public)

 content::item::content_methods_by_type [ -get_labels ] content_type

Determines all the valid content methods for instantiating a content type. Possible choices are text_entry, file_upload, no_content and xml_import. Currently, this proc merely removes the text_entry method if the item does not have a text mime type registered to it. In the future, a more sophisticated mechanism will be implemented.

Switches:
