Can I use WP_Query one time and then filter the results multiple times

Question

Wrap your WP_Query object in a function so you don’t have to change all the query $args.

The function will pass parameters for custom field value and order by custom field value.

Here how you can do it:

<?php
function custom_query($divided_cf_val=array(), $order_by_cf_val) {
?>
<div id="listings">
<?php
        $args = array(
    'post_type' => 'listing',
    'post_status' => 'publish',
    'posts_per_page' => '96',
    'meta_key' => 'price_value',
    'orderby' => $order_by_cf_val,
    'order' => 'ASC',
    'meta_query' => $divided_cf_val
);

$custom = new WP_Query( $args ); ?>
<h3 class="bar">Category 1 (<?php echo $custom -> found_posts; ?>)</h3>
    <?php $margincounter = 1; ?>
    <?php if ($custom->have_posts()) : while ($custom->have_posts()) : $custom->the_post(); ?>
    <?php include get_template_directory() . '/includes/listings_grid.php';      ?>n in y
    <?php endwhile; else: ?>
    <?php endif; wp_reset_query(); ?>
        </div>
<?php
}
?>

And call this function in your template like this:

<?php
$meta_field1 = array(
                array(
                    'key' => 'category_value',
                    'value' => 'category 1',
                    ),
                array(
                    'key' => 'sold_value',
                    'value' => 'No'
                    )
    );

$meta_field2 = array(
                    array(
                        'key' => 'category_value',
                        'value' => 'category 2',
                        ),
                    array(
                        'key' => 'sold_value',
                        'value' => 'Yes'
                        )
        );

$meta_field3 = array(
                    array(
                        'key' => 'category_value',
                        'value' => 'category 3',
                        ),
                    array(
                        'key' => 'sold_value',
                        'value' => 'Maybe'
                        )
        );

    custom_query($meta_field1, $order_by_cf_val);
    custom_query($meta_field2, $order_by_cf_val);
    custom_query($meta_field3, $order_by_cf_val);
    custom_query($meta_field4, $order_by_cf_val);
?>

and so on…
