# This uses code derived from: |
| 18 |
# - wp-rss-aggregate.php by Kellan Elliot-McCrea <kellan@protest.net> |
| 19 |
# - MagpieRSS by Kellan Elliot-McCrea <kellan@protest.net> |

# |
| 24 |
# INSTALLATION: see readme.txt or <http://projects.radgeek.com/install> |
| 25 |
# |
| 26 |
# USAGE: once FeedWordPress is installed, you manage just about everything from |
| 27 |
# the WordPress Dashboard, under the Syndication menu. To ensure that fresh |
| 28 |
# content is added as it becomes available, you can convince your contributors |
| 29 |
# to put your XML-RPC URI (if WordPress is installed at |
| 30 |
# <http://www.zyx.com/blog>, XML-RPC requests should be sent to |
| 31 |
# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the |
| 32 |
# Syndication menu, or set up automatic updates under Syndication --> Settings, |
| 33 |
# or use a cron job. |
| 34 |
|
| 35 |
# -- Don't change these unless you know what you're doing... |

| 1007 |
# |
| 1008 |
# Arguments: |
| 1009 |
# ---------- |
| 1010 |
# * $uri (string): either the URI of the feed to poll, the URI of the |
| 1011 |
# (human-readable) website whose feed you want to poll, or NULL. |
| 1012 |
# |
| 1013 |
# If $uri is NULL, then FeedWordPress will poll any feeds that are |
| 1014 |
# ready for polling. It will not poll feeds that are marked as |
| 1015 |
# "Invisible" Links (signifying that the subscription has been |
| 1016 |
# de-activated), or feeds that are not yet stale according to their |
| 1017 |
# TTL setting (which is either set in the feed, or else set |
| 1018 |
# randomly within a window of 30 minutes - 2 hours). |
| 1019 |
# |
| 1020 |
# Returns: |
| 1021 |
# -------- |
| 1022 |
# * Normally returns an associative array, with 'new' => the number |
| 1023 |
# of new posts added during the update, and 'updated' => the number |
| 1024 |
# of old posts that were updated during the update. If both numbers |
| 1025 |
# are zero, there was no change since the last poll on that URI. |
| 1026 |
# |
| 1027 |
# * Returns NULL if URI it was passed was not a URI that this |
| 1028 |
# installation of FeedWordPress syndicates. |
| 1029 |
# |
| 1030 |
# Effects: |
| 1031 |
# -------- |
| 1032 |
# * One or more feeds are polled for updates |
| 1033 |
# |
| 1034 |
# * If the feed Link does not have a hardcoded name set, its Link |
| 1035 |
# Name is synchronized with the feed's title element |
| 1036 |
# |
| 1037 |
# * If the feed Link does not have a hardcoded URI set, its Link URI |
| 1038 |
# is synchronized with the feed's human-readable link element |
| 1039 |
# |
| 1040 |
# * If the feed Link does not have a hardcoded description set, its |
| 1041 |
# Link Description is synchronized with the feed's description, |
| 1042 |
# tagline, or subtitle element. |
| 1043 |
# |
| 1044 |
# * The time of polling is recorded in the feed's settings, and the |
| 1045 |
# TTL (time until the feed is next available for polling) is set |
| 1046 |
# either from the feed (if it is supplied in the ttl or syndication |
| 1047 |
# module elements) or else from a randomly-generated time window |
| 1048 |
# (between 30 minutes and 2 hours). |
| 1049 |
# |
| 1050 |
# * New posts from the polled feed are added to the WordPress store. |
| 1051 |
# |
| 1052 |
# * Updates to existing posts since the last poll are mirrored in the |
| 1053 |
# WordPress store. |
