bp_action_variables are stored as an array

That does make it easy. you just have to ‘catch’ them right?

so if somebody randomly entered the URL posts/page/2/3/hello and I did something like

if ( $bp->action_variables[2] == 'hello' ) {
// do something
} else {
// do nothing
}

then ‘do something’ would happen
