Add function to a given gravity forms extension

I need an update of this plugin : [login to view URL] Currently the plugin extends Gravity Forms with the possibility to use date fields at the conditional logic section. See Screenshoot 1. What you have to do : - extend the plugin, so this will also work at the conditional section from the GF Settings API ( [login to view URL] ) - extend the plugin so it's possible to use placeholders that will be replaced with the assigned value at execution time (not at 'design' time ) -- {date} = the current date -- {entry_date} = the date of the entry - extend the possibility to use calculcations with the placeholders (examples) -- {date} - 1d = the current date - 1 day -- {date} - 1w = the current date - 1 week -- {date} - 1m = the current date - 1 month -- {date} - 1y = the current date - 1 year You need to work on your own environment and must have Gravity Forms ( i don't send it ) I don't work with freelancers who need to adjust their bid. You don't have to change the code of Gravity Forms. For a GF professional this should be only some hours of work.
