What is a jump tag? Well, many people (including the author) didn’t like the really long URLs that Mig uses because it made it clumsy to paste them into an email or a chat window. However, changing them now would be difficult to do and certainly not backward-compatible.
Jump tags were invented to address this problem. Take this URL for example:
https://example.com/gallery/index.php?pageType=folder&currDir=./Our%20House/Before%20We%20Redecorated
At 105 characters long, and having tons of URL-encoded
%xx entities in it, it’s an ugly URL to send someone. But
the pain can be alleviated. The jump map defines shortcuts for long
URLs.
Add a line to config.php that adds to the jump map.
$jumpMap['me'] = 'currdir=./Pictures_of_me';Now “me” is defined as a shortcut for a folder at the root of the album called “Pictures of me”. The long URL above would look like this:
$jumpMap['house'] = 'currDir=./Our%20House/Before%20We%20Redecorated';All that is needed is the value of currDir (which can be
copied from the address bar in most web browsers). Now this URL will go
to the same place:
https://example.com/gallery/?jump=houseMuch shorter and nicer. If an album has four or five levels deep (such as some of the albums I maintain), the URLs can be very long.
There are two ways to do this, too. The first is shown above. Another way is a URL like this:
https://example.com/gallery/index.php/houseWhich avoids clumsy stuff like the ? in the URL. It’s a matter of preference which one to use. Note that with the second method it can’t be shortened like this:
https://example.com/gallery/houseBecause the web server will look for that directory, not find it, and
return an error. So that index.php or
index.php3 has to be in there.
This works with Apache web servers. I don’t know if it works with anything else. If you’re running something other than Apache, let me know how you fare with this feature.
Also see the apache document which has some nifty
mod_rewrite ideas to utilize shorter, simpler URLs.
