# class SyndicatedLink: represents a syndication feed stored within the |
| 3 |
# WordPress database |
| 4 |
# |
| 5 |
# To keep things compact and editable from within WordPress, we use all the |
| 6 |
# links under a particular category in the WordPress "Blogroll" for the list of |
| 7 |
# feeds to syndicate. "Contributors" is the category used by default; you can |
| 8 |
# configure that under Options --> Syndication. |
| 9 |
# |
| 10 |
# Fields used are: |
| 11 |
# |
| 12 |
# * link_rss: the URI of the Atom/RSS feed to syndicate |
| 13 |
# |
| 14 |
# * link_notes: user-configurable options, with keys and values |
| 15 |
# like so: |
| 16 |
# |
| 17 |
# key: value |
| 18 |
# cats: computers\nweb |
| 19 |
# feed/key: value |
| 20 |
# |
| 21 |
# Keys that start with "feed/" are gleaned from the data supplied |
| 22 |
# by the feed itself, and will be overwritten with each update. |
| 23 |
# |
| 24 |
# Values have linebreak characters escaped with C-style |
| 25 |
# backslashes (so, for example, a newline becomes "\n"). |
| 26 |
# |
| 27 |
# The value of `cats` is used as a newline-separated list of |
| 28 |
# default categories for any post coming from a particular feed. |
| 29 |
# (In the example above, any posts from this feed will be placed |
| 30 |
# in the "computers" and "web" categories--*in addition to* any |
| 31 |
# categories that may already be applied to the posts.) |
| 32 |
# |
| 33 |
# Values of keys in link_notes are accessible from templates using |
| 34 |
# the function `get_feed_meta($key)` if this plugin is activated. |
