Math filters: How to target a specific field value with [gravitymath] filters

The "filter" parameter only works with scope="view" or scope="form" . More about that here: The [gravitymath] Shortcode.

Assuming you have a form like this one:

...and a View like this one:

Now, you want to calculate the sum between Number 1 and Number 2, only for the entries where the value of the Calculate field is "Yes". That's now possible with the "filter" parameter of the [gravitymath] shortcode.

Here's our shortcode:

Total: [gravitymath scope="view" id="8" filter="filter_1=Yes&op_1=is"]{Number 1:2}+{Number 2:3}[/gravitymath]

...and here's the output in the View:


The following attributes for the "filter" parameter are supported:

filter_N  - the filter, where N is the ID of the field or meta key

op_N  - the operation for a corresponding filter_N , default: is , other operators are isnot , contains , notcontains , lt (less than), and gt (greather than).

limit  - the number of entries to calculate. Leave it blank to use all entries from the chosen "scope" parameter.

In the example below, we are filtering the field Calculate (ID = 1) for the "Yes" value.

[gravitymath scope="view" id="206" filter="filter_1=Yes&op_1=is"]...[/gravitymath]

If we wanted to filter by two fields instead, for example, Calculate =Yes and Number 2 = 6, then we'll do it like this:

[gravitymath scope="view" id="206" filter="filter_1=Yes&op_1=is&filter_3=Yes&op_3=is"]...[/gravitymath]

Pay attention to the fact that filter_1 and op_1 correspond to the first field Calculate (ID = 1), and filter_3 and op_3 correspond to the field Number 2 (where ID = 3).

Use values on the filter parameter, not labels

If you are filtering a choice-based field, like a dropdown, that uses values instead of only labels, then the filter will look for the value and not the label:


[gravitymath ... filter="filter_1=first_choice"]...[/gravitymath]
