This is development work for a client, so unfortunately I can’t freely give out the development link (plus it’s currently restricted by ip address). I am referring to events-search.php. I have searched the forums extensively, and the only solution I saw suggested adding a multi-select, or replacing the select with a checkbox group, but I am still not sure how and where I’d modify the corresponding sql statement. The function wp_dropdown_categories could perhaps be replaced with wp_category_checklist but I’m not quite sure how to implement that effectively, and more importantly, what else I’d need to modify in events manager to make it work. From events-search.php:
<?php if( get_option('dbem_search_form_categories') ): ?>
<!-- START Category Search -->
<?php
$selected = !empty($_REQUEST['category']) ? $_REQUEST['category'] : 0;
EM_Object::ms_global_switch(); //in case in global tables mode of MultiSite, grabs main site categories, if not using MS Global, nothing happens
wp_dropdown_categories(array( 'hide_empty' => 0, 'orderby' =>'name', 'name' => 'category', 'hierarchical' => true, 'taxonomy' => EM_TAXONOMY_CATEGORY, 'selected' => $selected, 'show_option_none' => get_option('dbem_search_form_categories_label'), 'class'=>'em-events-search-category'));
EM_Object::ms_global_switch_back(); //if switched above, switch back
?>
<!-- END Category Search -->
<?php endif; ?>
I really appreciate any ideas on this one. I currently have a number of categories that need to have the capability to be multi-selected and displayed with the search (ie, show all posts that match any of the selected categories).
