I’m trying to set up some custom filters for Filter Bar. I need to do some things that don’t involve the simple system provided.<\/p>\n
I’ve set up a basic custom filter easy enough following the advice here: https:\/\/theeventscalendar.com\/support\/forums\/topic\/adding-custom-filter-to-filter-bar-2\/ As long as you have a taxonomy or custom field you want to filter against, just populate the values for a drop-down, all works great.<\/p>\n
However, I’m trying to replace the ‘Cost’ filter with one that is simply a checkbox to filter and only show events that are free. I know this is possible with the ‘Cost’ filter, but we need the interface to be simpler, we don’t want comprehensive cost filtering, just “free?”, or show everything. And we need some other, more complex filters. I thought it would be good to start with the problems with this one, it may help on the way to the more complex ones.<\/p>\n
The code I’ve got so far is here: https:\/\/gist.github.com\/gyrus\/af981f6e3ab19a940b59<\/p>\n
Using Query Monitor the query being performed is this: http:\/\/pastebin.com\/iETYQNep<\/p>\n
The join for the event cost meta field seems to give the alias Further, does this lead to issues with applying multiple custom filters at once?<\/p>\n Anyway, it’d be good to get this simple one working first!<\/p>\n","protected":false},"template":"","class_list":["post-970860","topic","type-topic","status-closed","hentry"],"yoast_head":"\nmt1<\/code> to the meta table, but the OR condition seems to be using both this and the plain meta table name. Is this part of the issue? I wonder if this is something to do with the filter bar setup_query_args() setting args rather than concatenating them?<\/p>\n
