The plugin is based on (MathExecutor)[https://github.com/neonxp/MathExecutor]. It supports all the operators and functions that are supported in MathExecutor. The plugin uses (MathPHP)[https://github.com/markrogoyski/math-php] for additional math functions
I'm trying to define the end of a time range based on a dynamic starting date.
example for formula: https://dropit.psy.unibe.ch/admin/cms_update/97/update/prop
Maybe the formula parser can support something like strtotime() or date_add() ?
I'm trying formulas like:
date('Y-m-d', strtotime('{{first_entry_date_formatted}}'. ' + 7 days')) or date_add('{{first_entry_date_formatted}}', date_interval_create_from_date_string("7 days"))
but I can't generate the new date that I want.
