Tags are only available in text mode. You can nest tags inside each other. There must always be a corresponding end tag for each tag.
if/elseif/else/endif
These tags all work together to allow you to conditionally evaluate sections in text mode.
At its simplest, you can have an if and endif pair:
If this is run with a user named Alice, it will output Hi Alice, but if the user has no name it will just output Hi.
You can also add an else block to act as a catch-all:
Now if the user has no name it will output Hi there.
Finally, you can add more conditions using elseif:
You can add as many additional conditions with elseif as you like.
As mentioned above, Formulas does not coerce types, with all but NULL & FALSE being truthy. To check if a value is blank simply write the following:
for/endfor
The for tag allows you to repeat the same block of code multiple times for each item in an array.
This will output User names: followed by the names of all the users in the array users.
Within a for tag, there is a special FORLOOP variable available with the following properties:
FORLOOP.index0: The zero based index of the current loop iteration. That is the first time through the loop this will be 0, the second time 1 and so on.FORLOOP.index: The one based index of the current loop iteration. That is the first time through the loop this will be 1, the second time 2 and so on.FORLOOP.first: This will be true the first time through the loop.FORLOOP.last: This will be true the last time through the loop.
For example, if we wanted to output a comma between every name we could do something like this:
