将过滤器添加到 wordpress 查询

Question

My issue is as follows; I have fields with no value showing on my page - I want them to be hidden, until they have a value. In my code I have a meta_value_num as a sorting option per today. But it still shows values that are 0(zero) and blanks.

Please tell me how I can filter these so that the empty ones are not shown. Eg if I can sort everything with a value = 100 and above, that would be good enough.

This is how the code looks per today:

$tax = $wp_query->get_queried_object();
$new_query = new WP_Query( array( 
    'post_type' => 'clinic',
    'meta_key' => $treatment,
    'orderby' => 'meta_value_num',
    'order' => 'DSC',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'location',
            'field'    => 'ID',
            'terms'    => $tax->term_id
             )
        ),
));

Answer 1

I managed to fix the filter issue.

By adding this code it now filters out everything below 20 and shows all above. Big shout out to @Cbroe for pointing me in the right direction!

'meta_value' => '20', 'meta_compare' => '>=',

Code now looks like this;

$tax = $wp_query->get_queried_object();
$new_query = new WP_Query( array( 
    'post_type' => 'clinic',
    'meta_key' => $treatment,
    'meta_value'   => '20',
    'meta_compare' => '>=',
    'orderby' => 'meta_value_num',
    'order' => 'ASC',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'location',
            'field'    => 'ID',
            'terms'    => $tax->term_id
             )
        ),
));
