Hi,

Eileen pointed out that we don't properly handle the MembershipContact and other 2 words entities.

I'm tempted to solve the problem by renaming the functions, but wanted to check if there is a function somewhere that translates MembershipContact into membership_contact so I can use it for the functions.

Hmm - this is what I used in the function that generated the examples. I can see from the comment that it was waiting for a Belgian touch

        if (strstr($entity,'UF')){// a cleverer person than me would do it in a single regex
         $fnPrefix = strtolower(preg_replace('/(?<! )(?<!^)(?<=UF)[A-Z]/','_$0', $entity));         
        }else{
        $fnPrefix = strtolower(preg_replace('/(?<! )(?<!^)[A-Z]/','_$0', $entity));
        } 

I made this function one day (found it in gitorious).
It is adapted from the linked blog post, but I don't remember if it is identical.
The tricky part was how to deal with multi-uppercase, like in "BBCode" or "EatABanana".
In some cases we want eat_a_banana, in others we want eat_abanana".
I don't remember what this one does exactly.

EDIT: Now I remember!!!
This was a genius piece of mine
The example string is used for configuration, so the user does not have to remember some arbitrarily named options.
Example: You want that "EatABanana" explodes as "Eat A Banana", not "Eat ABanana". You put "Eat A Banana" as a the example string.
Now if you want to explode "VerticalYDim", it would become "Vertical Y Dim" and not "Vertical YDim".
On the other hand, with an example string of "Eat ABanana", the "VerticalYDim" would explode as "Vertical YDim".
The overhead for this convenience is only executed one time, if you can stick with one example string.
Wow.
I think this is why I remembered this piece.
Does it work? No idea..
And the comment block is not very accurate, I must say.

EDIT:
Updated the comment block.

Hi Andreas,

That's until you got a handful of posts, after a while, mr forum gets to know you and become relaxed

Didn't find the holy regexp, but added a str_replace in the chain and voila, seems to work

api/api.php Committed revision 32774

$function = strtolower(str_replace('U_F','uf', preg_replace('/(?=[A-Z])/','_$0', $entity)));
