Modify integer field to negative - duration
March 22, 2010, 10:37:06 am
I would like the duration of an activity to accept a negative integer, currently it only accepts positive integers.  How can I modify this ??

Our volunteers will receive credit for their time on an activity.  They will be able to "Cash-in" that time and receive stuff in return.

I would like to be able to add an activity for when they cash-in that will permit a negative integer in the duration field, so that when we run an activity report that I've modified to include duration, the total duration can be calculated as either their total volunteer time, or the remaining "cash-in" time they have available.

Appreciate any thoughts/suggestions
Thanks -Duane.

I suspect you can modify the code here to allow negative numbers:

CRM/Activity/Form/Activity.php, line 543. to allow all integers (instead of just positive integers)

I dont think we have any other code that uses duration, so i suspect this is a safe change. If you do write an activity report to do the below please publish it so others can benefit

any chance you can point me to where the rules are located?

In the activity.php file you referenced, I modified the rule that tests for 'positiveInteger' to simple Integer and allInteger and get errors that there is no rule by that name.

I can't find the rules that do these tests to locate the correct rule name that might permit a negative Integer.

thanks for your advice - Duane

CRM/Utils/Rule.php

change 'positiveInteger' to 'integer' and that should work
