42C4::NewsChannels - Functions to manage the news channels and its categories
43
44=head1 DESCRIPTION
45
46This module provides the functions needed to admin the news channels and its categories
47
48=head1 FUNCTIONS
49
50=over 2
51
52=item news_channels
53
54 ($count, @channels) = &news_channels($channel_name, $id_category, $unclassified);
55
56Looks up news channels by name or category.
57
58C<$channel_name> is the channel name to search.
59
60C<$id_category> is the channel category code to search.
61
62C<$$unclassified> if it is set and $channel_name and $id_category search for the news channels without a category
63
64if none of the params are set C<&news_channels> returns all the news channels.
65
66C<&news_channels> returns two values: an integer giving the number of
67news channels found and a reference to an array
68of references to hash, which has the news_channels and news_channels_categories fields.

98
99Looks up news channels grouped by category.
100
101C<&news_channels_by_category> returns two values: an integer giving the number of
102categories found and a reference to an array
103of references to hash, which the following keys:
104
105=over 4
106
107=item C<channels_count>
108
109The number of news channels in that category
110
111=item C<channels>
112
113A reference to an array of references to hash which keys are the new_channels fields.
114
115Additionally the last index of results has a reference to all the news channels which don't have a category
