# This uses code derived from: |
| 14 |
# - wp-rss-aggregate.php by Kellan Elliot-McCrea <kellan@protest.net> |

# INSTALLATION: see readme.txt or <http://projects.radgeek.com/install> |
| 20 |
# |
| 21 |
# USAGE: once FeedWordPress is installed, you manage just about everything from |
| 22 |
# the WordPress Dashboard, under the Syndication menu. To ensure that fresh |
| 23 |
# content is added as it becomes available, you can convince your contributors |
| 24 |
# to put your XML-RPC URI (if WordPress is installed at |
| 25 |
# <http://www.zyx.com/blog>, XML-RPC requests should be sent to |
| 26 |
# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the |
| 27 |
# Syndication menu, or set up automatic updates under Syndication --> Settings, |
| 28 |
# or use a cron job. |
| 29 |
|
| 30 |
# -- Don't change these unless you know what you're doing... |

# function update (): polls for updates on one or more Contributor feeds |
| 556 |
# |
| 557 |
# Arguments: |
| 558 |
# ---------- |
| 559 |
# * $uri (string): either the URI of the feed to poll, the URI of the |
| 560 |
# (human-readable) website whose feed you want to poll, or NULL. |
| 561 |
# |
| 562 |
# If $uri is NULL, then FeedWordPress will poll any feeds that are |
| 563 |
# ready for polling. It will not poll feeds that are marked as |
| 564 |
# "Invisible" Links (signifying that the subscription has been |
| 565 |
# de-activated), or feeds that are not yet stale according to their |
| 566 |
# TTL setting (which is either set in the feed, or else set |
| 567 |
# randomly within a window of 30 minutes - 2 hours). |
| 568 |
# |
| 569 |
# Returns: |
| 570 |
# -------- |
| 571 |
# * Normally returns an associative array, with 'new' => the number |
| 572 |
# of new posts added during the update, and 'updated' => the number |
| 573 |
# of old posts that were updated during the update. If both numbers |
| 574 |
# are zero, there was no change since the last poll on that URI. |
| 575 |
# |
| 576 |
# * Returns NULL if URI it was passed was not a URI that this |
| 577 |
# installation of FeedWordPress syndicates. |
| 578 |
# |
| 579 |
# Effects: |
| 580 |
# -------- |
| 581 |
# * One or more feeds are polled for updates |
| 582 |
# |
| 583 |
# * If the feed Link does not have a hardcoded name set, its Link |
| 584 |
# Name is synchronized with the feed's title element |
| 585 |
# |
| 586 |
# * If the feed Link does not have a hardcoded URI set, its Link URI |
| 587 |
# is synchronized with the feed's human-readable link element |
| 588 |
# |
| 589 |
# * If the feed Link does not have a hardcoded description set, its |
| 590 |
# Link Description is synchronized with the feed's description, |
| 591 |
# tagline, or subtitle element. |
| 592 |
# |
| 593 |
# * The time of polling is recorded in the feed's settings, and the |
| 594 |
# TTL (time until the feed is next available for polling) is set |
| 595 |
# either from the feed (if it is supplied in the ttl or syndication |
| 596 |
# module elements) or else from a randomly-generated time window |
| 597 |
# (between 30 minutes and 2 hours). |
| 598 |
# |
| 599 |
# * New posts from the polled feed are added to the WordPress store. |
| 600 |
# |
| 601 |
# * Updates to existing posts since the last poll are mirrored in the |
| 602 |
# WordPress store. |

# WordPress database |
| 2057 |
# |
| 2058 |
# To keep things compact and editable from within WordPress, we use all the |
| 2059 |
# links under a particular category in the WordPress "Blogroll" for the list of |
| 2060 |
# feeds to syndicate. "Contributors" is the category used by default; you can |
| 2061 |
# configure that under Options --> Syndication. |
| 2062 |
# |
| 2063 |
# Fields used are: |
| 2064 |
# |
| 2065 |
# * link_rss: the URI of the Atom/RSS feed to syndicate |
| 2066 |
# |
| 2067 |
# * link_notes: user-configurable options, with keys and values |
| 2068 |
# like so: |
| 2069 |
# |
| 2070 |
# key: value |
| 2071 |
# cats: computers\nweb |
| 2072 |
# feed/key: value |
| 2073 |
# |
| 2074 |
# Keys that start with "feed/" are gleaned from the data supplied |
| 2075 |
# by the feed itself, and will be overwritten with each update. |
| 2076 |
# |
| 2077 |
# Values have linebreak characters escaped with C-style |
| 2078 |
# backslashes (so, for example, a newline becomes "\n"). |
| 2079 |
# |
| 2080 |
# The value of `cats` is used as a newline-separated list of |
| 2081 |
# default categories for any post coming from a particular feed. |
| 2082 |
# (In the example above, any posts from this feed will be placed |
| 2083 |
# in the "computers" and "web" categories--*in addition to* any |
| 2084 |
# categories that may already be applied to the posts.) |
| 2085 |
# |
| 2086 |
# Values of keys in link_notes are accessible from templates using |
| 2087 |
# the function `get_feed_meta($key)` if this plugin is activated. |
