IteratorVariables

[edit] Iterator Variables

Those variables are special variables that are automatically added to the $dwoo variables when you run an iterator plugin (foreach, loop or for).

first (bool) : true if the item being processed is the first, false otherwise
last (bool) : true if the item being processed is the last one, false otherwise
index (int) : the index number (starts from 0 and increases by 1 at each iteration)
iteration (int) : the iteration number (starts from 1 and increases by 1 at each iteration)
show (bool) : true if the loop will display something, false otherwise
total (int) : the total amount of items in the array

You access them through {$dwoo.<plugin (foreach, loop or for)>.<foreach name>.<var>}
If you don't provide the name argument to a plugin, it will use the name "default" by default, which means that for example you can access a foreach var with {$dwoo.foreach.default.first}
The $dwoo var can be shortened as $ which means that {$.foreach.default.first} would also work.
