Example:
http://thepursesociety.com/_web/category/houses
Filtering works fine, however, top menu disappears when the result is displayed. The code I am using is below:
In functions.php
add_action('pre_get_posts', 'my_pre_get_posts');
function my_pre_get_posts( $query ) { // validate if( is_admin() ) { return; }
// get original meta query
$meta_query = $query->get('meta_query');
// allow the url to alter the query
// eg: http://www.website.com/events?location=melbourne
// eg: http://www.website.com/events?location=sydney
if( !empty($_GET['bedrooms']) )
{
$bedrooms = explode(',', $_GET['bedrooms']);
//Add our meta query to the original meta queries
$meta_query[] = array(
'key' => 'bedrooms',
'value' => $bedrooms,
'compare' => 'IN',
);
}
// update the meta query args
$query->set('meta_query', $meta_query);
// always return
return;
}
In category.php
<div id="search-houses">
<?php
$field = get_field_object('bedrooms');
$values = explode(',', $_GET['bedrooms']);
?>
<ul>
<?php foreach( $field['choices'] as $choice_value => $choice_label ): ?>
<li>
<input type="checkbox" value="<?php echo $choice_value; ?>" <?php if( in_array($choice_value, $values) ): ?>checked="checked"<?php endif; ?> /> <?php echo $choice_label; ?></li>
</li>
<?php endforeach; ?>
</ul>
</div>
<script type="text/javascript">
(function($) {
$('#search-houses').on('change', 'input[type="checkbox"]', function(){
// vars
var $ul = $(this).closest('ul'),
vals = [];
$ul.find('input:checked').each(function(){
vals.push( $(this).val() );
});
vals = vals.join(",");
window.location.replace(location.pathname + '?bedrooms=' + vals);
console.log( vals );
});
})(jQuery);
</script>
Hi @uakz
Your pre_get_posts filter has the potential to affect every WP_Query on the page! This would explain why your top menu is not returning the correct data.
Looking at the WP docs: http://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts it seems that another validation is done in the filter to make sure this is the main query on the page:
if ( !is_admin() && $query->is_main_query() ) {
So you could add another line to the top of your filter like this:
// validate if( !$query->is_main_query() ) { return; }
hope that helps
