I'm working with this directory site theme and in the search function, it has the "Search by: Category" option.
I'd like to rename that to "Search by: Location" and when people click the drop-down, it should only display the parent categories, which are the location names. It should not show any of the sub-categories.
here's the code...
<div class="col-lg-4">
<div class="dropdown dropdown-category">
<select name="dropdown_category4" class="btn btn-secondary dropdown-toggle" type="button" id="listing_category">
<option value="" selected><?php _e('Search by: Category', 'directorytheme'); ?></option>
<?php
$terms_links = get_terms('listing-categories');
foreach( $terms_links as $terms_link ) : ?>
<option class="dropdown-item dropdown-cat" value="<?php echo "{$terms_link->slug}"; ?>"><?php echo "{$terms_link->name}"; ?></option>
<?php endforeach; ?>
</select>
<?php if($listing_category != '') : ?>
<input type="hidden" name="s_listing_category" id="s_listing_category" value ="<?php echo $listing_category; ?>">
<?php else : ?>
<input type="hidden" name="s_listing_category" id="s_listing_category">
<?php endif; ?>
</div><!--dropdown-->
</div>
How can I modify it to do what I need it to do?
Thanks!
You can pass an array of parameters into get_terms.
get_terms(array(
'taxonomy' => 'listing-categories',
'parent' => 0
));
parent 0 means top level terms.
