Editing WoW:API GetChannelName (section)

{{wowapi}}

Retrieves the id and the name from a specific channel. 

 id, name = GetChannelName(id);

----
;''Arguments''

:;id : The numeric id of the channel you want to query, or a string containing the name of the channel.

----
;''Returns''

:;id : a number containing the id of the channel, e.g. 2, or 0 if the channel is not found
:;name : a string containing the name of the channel, e.g. "Trade - Stormwind", or nil if the channel is not found or the id parameter was a name.
----
;''Important''

If the channel argument is the channel name (ie "testchan1"), then the returned channel name is a nil value.
If the channel argument is the channel number (ie 6 or "6"), then the returned channel name is correct.
The channel id returns correctly in both cases.

It's also worthy to note the strange behaviour of (at least) Trade channels. Login to a city, GetChannelName("Trade - City") will return the channel number it's on. Step outside the city, you'll leave the channel yet making that call again will return the channel number you *were* on. As such, it's not entirely reliable for detecting if you're in a trade enabled zone.
 
----
;''Example''
 -- Check if the specific channel exists
 myChannel = 1;
 id, name = GetChannelName(myChannel);
 if (id > 0 and name ~= nil) then
   SendChatMessage("This is just a test.", "CHANNEL", nil, id);
 end

;''Result''

Checks if the channel with id stored in myChannel exists and in this case sends the text "This is just a test" to it.
