Concepts

This section introduces some key concepts that are crucial to understanding how these functions work in PhixFlow. The concepts are should be fairly straightforward for anyone used to using excel, or any type of database. But PhixFlow is capable of supporting some complex transformations, where needed, and it is important that you are comfortable with these concepts before setting up elaborate function configurations.

...

Where a function can take, as one of its arguments, a list of values this is expressed in square brackets, e.g.:
function([value1, value2, ...])
See Arrays and Record Sets for details of how lists are handled in functions. Such a list is often called a vector. Indexes: always start at 1. Many functions return an index, indicating the position in a list at which a matched value has been found. E.g. see getElement.

• + (add; can also use the attribute function sum)
• - (minus; can also use the attribute function sum, reversing the sign of the second operand)
• / (divide)
• * (multiply)

The attribute functions are categorised below for easy searching.

Performance

Certain functions can be evaluated on the client and expressions including only these functions will be evaluated on the client. Expressions including other functions must be evaluated on the server. The following functions can be evaluated on the client: 

• And 
• Dot (e.g. _form.UID) 
• Equals 
• Greater than 
• Greater than or equals 
• IsEmpty 
• IsNull 
• Less than 
• Less than or equals 
• Minus 
• Not 
• Not equals 
• Now 
• Or 
• Plus 
• Today
