Custom Taxonomy Search and Multiselector Problem

Hi,

Have you tried BP Profile Search plugin?

The normal buddypress search will only work with ids but bp profile search will allow you to search by tags.

I have this issue also.

“The normal buddypress search will only work with ids but bp profile search will allow you to search by tags.”

That’s not quite true.

With the default set of xprofile fields if you choose multi select or checkboxes it generates links like this for the resulting autolink fields:

https://www.mysite.com/people/?members_search=interest2

^ this works fine.

However if I change the links generated by the taxonomy field from id to text it doesn’t work.

What’s the difference?

I’ve modified the code and it seems to work.

Save this code as ‘BXcft_Field_Type_MultiSelectCustomTaxonomy_Custom.php’

and include the file in your theme, for example:

Add this to your themes functions.php

require_once(‘inc/classes/BXcft_Field_Type_MultiSelectCustomTaxonomy_Custom.php’);

<?php
   	class Bxcft_Field_Type_MultiSelectCustomTaxonomy extends BP_XProfile_Field_Type

            $this->supports_multiple_defaults   = true;
            $this->supports_options             = true;

            $this->set_format( '/^.+$/', 'replace' );
            do_action( 'bp_xprofile_field_type_multiselect_custom_taxonomy', $this );
