Hello,
I am using Joomla 6 with Community Builder and have created a custom Joomla module containing an interactive country map.
When a country is selected, the module should open a Community Builder user list filtered by:
cb_address_country
The current field is a Query Drop Down (Single Select) and stores ISO2 values such as:
KE
US
JM
The field is published, searchable, and explicitly included in the list’s specified searchable fields.
Community Builder’s own search form works correctly. For example, selecting Kenya through the native search form returns only members whose stored value is KE.
An important detail is that the external filtering worked previously when Country was stored in a regular text field. We changed it to a Query Drop Down so that country values would remain standardized and could be filtered reliably over the long term.
Since making that change, the native Community Builder search still works, but the external module no longer applies the filter.
I have tested GET requests such as:
/member-directory?cb_address_country=KE
and:
/member-directory?searchmode=0&search=&limitstart=0&cb_address_country=KE
I also tested a POST request containing:
listid=4
limitstart=0
search=
cb_address_country=KE
[Joomla CSRF token]=1
In each case, the correct user list opens, but all members are displayed.
The native Community Builder form submits the same ISO2 country value by POST and filters correctly.
Could you please explain the supported way for an external Joomla module to reproduce this Community Builder user-list search? Is there something different about externally filtering a Query Drop Down field, or is an additional Community Builder search-state, security, session or hotlink-protection value required?
Thank you.
Joomla version: 6.1.2
Community Builder version:
