Add "IDs only" return format option for BP_Signup::get().

[espellcaste]

Inspired by #7609. I think BP_Signup::get() could use an update for fetching ids only.

Patch in the works.

Correct one!

While we're changing this code:

 $signup->id   = intval( $signup->signup_id );

Can you please look into why this value is not being returned as an integer? Is it a bug somewhere else (our code, or WP's)?

[DJPaul]

Apart from that small question, I think this patch is looking fine! 👍

@DJPaul I'm not sure where to look. I looked at how it is added and don't see a problem there. I'll defer this question to @boonebgorges, he is well versed in BP_Signup than me and probably will answer better.

So far, I presume whoever did that wanna just to ensure it is an integer.

About the patch, great! :)

$signup is a row pulled from a $wpdb->get_results() database query. $wpdb->get_results() results are always arrays/objects with string values. ​https://buddypress.trac.wordpress.org/browser/tags/2.9.2/src/bp-members/classes/class-bp-signup.php?marks=210,222#L200
