on a quick glance, i see 2 possibilities:
a) modify the source. search all files for feed_freq_hours
, change all occurrences to feed_freq_minutes
, and fix all references (eg. instead of $feed->feed_freq_hours * 3600
, you will have to use $feed->feed_freq_minutes * 60
). you will also have to rename the feed_freq_hours
column of the [table_prefix]feeds
table. good luck!
b) (ab)use feed_freq_hours
for minutely update frequencies by using fractional hours: eg. for an update every 10 minutes, enter 0.1666667
(a sixth of an hour). this will need a change of the feed_freq_hours
column from int
to float
, eg. ALTER TABLE [table_prefix]feeds CHANGE feed_freq_hours feed_freq_hours float
.
