Customizing AJAX result

Here’s a live sample version of how I’ve implemented this.
http://www.trevelations.com/dev/university-acceptance-profile/

If you try the search filter with no criteria selected you’ll see that all the results are returned as expected by they are out of order.

I’ll quit being a pain in the butt soon.

I’ve now found how I can inject custom arguments into the loop thanks to one of your previous posts, and right now the relevant functions within my functions.php are as follows:

function customorderby($orderby) {
    return 'mt1.meta_value DESC, mt2.meta_value ASC, mt3.meta_value ASC';
}

/************
CUSTOMIZE AJAX RESULT OF ULTIMATE WORDPRESS QUERY SEARCH FILTER
************/ 

add_filter('uwpqsf_result_tempt', 'customize_output', '', 4);
function customize_output($results , $arg, $id, $getdata ){
	 // The Query
            $apiclass = new uwpqsfprocess();
			$query = new WP_Query( $arg );

			$result = array (
				'posts_per_page' => 3
			);

			ob_start();	$result = '';

		// The Loop

			if ( $query->have_posts() ) {
			echo '<h2>Search results
					<span style="float:right;">
						<a href="" class="arconix-button arconix-button-small arconix-button-red" style="font-size:12px;">Reset</a>
					</span>
					</h2>

			<table id="uniprofile">
				<tr class="head">
					<td>Class</td>
					<td>University</td>
					<td>Country</td>
					<td>Acceptances</td>
					<td>Offers</td>
					<td>Matriculations</td>';

			while ( $query->have_posts() ) {
				$query->the_post(); ?>

			<tr>
                <td><?php meta('uni-class'); ?></td>
                <td><a href="<?php get_permalink(); ?>" rel="bookmark"><?php meta('uni-name'); ?></a></td>
                <td><?php meta('uni-country'); ?></td>
                <td class="stat"><?php meta('uni-acceptances'); ?></td>
                <td class="stat"><?php meta('uni-offers'); ?></td>
                <td class="stat"><?php meta('uni-matriculations'); ?></td>
            </tr>

			<?php }
                        echo  $apiclass->ajax_pagination($arg['paged'],$query->max_num_pages, 4, $id, $getdata);

					} else {

						echo  'no post found';
				}
				/* Restore original Post Data */
				wp_reset_postdata();

		$results = ob_get_clean();
			return $results;
}

add_filter('uwpqsf_query_args','injecting_custom_arg','',4);
function injecting_custom_arg($args, $id,$getdata){
  //$getdata is the data from the form input. Using it like GET url parameter
 $args['meta_key'] = 'uni-class';
 $args['posts_per_page'] = -1;
 $args['meta_query'] = array(array(array('key' => 'uni-class'), array('key' => 'uni-country'), array('key' => 'uni-name')));

 return $args;
}

So now I only need to figure out how to apply the customorderby function or sort the results by those 3 respective meta_keys.

Thanks a lot

I successfully customized the query using this function in my functions.php file:

add_filter('uwpqsf_query_args','injecting_custom_arg','',4);
function injecting_custom_arg($args, $id,$getdata){
  //$getdata is the data from the form input. Using it like GET url parameter
 $args['meta_key'] = 'uni-class';
 $args['posts_per_page'] = -1;
 $args['meta_query'] = array(array(array('key' => 'uni-class'), array('key' => 'uni-country'), array('key' => 'uni-name')));

 return $args;
}

This function is a completely separate function to your plugin/the ajax search results:

function customorderby($orderby) {
    return 'mt1.meta_value DESC, mt2.meta_value ASC, mt3.meta_value ASC';
}

It allows me to sort my nested query by multiple meta_keys (uni-class, then uni-country, then uni-name) on my page template as follows (prior to filtering the results with your plugin). The relevant lines of code to apply this filter are:

add_filter('posts_orderby','customorderby');
[Nested Query]
remove_filter('posts_orderby','customorderby');

In application, it looks like this in my custom page template:

<?php

						/*$all = get_posts(array(
							'post_type'=> 'university',
							'posts_per_page' => -1)
						);

						$parents = array();

						foreach ($all as $single)

						{
							$kids = get_children($single->ID);  

							if(isset($kids) && !empty($kids) && count($kids) >= 1)

							{
								$parents[] = $single->ID;
							}
						}*/

						$args = array(
							'post_type' => 'university',
							'posts_per_page' => -1,
							/*'post__not_in' => $parents,*/
							'meta_key' => 'uni-class',
							'meta_query'   => array(
								array(
									'key' => 'uni-class'
								),
								array(
									'key' => 'uni-country'
								),
								array(
									'key' => 'uni-name'
								)
							)
						);

						add_filter('posts_orderby','customorderby');
						$uniplace = new WP_Query($args);
						while ($uniplace->have_posts() ) : $uniplace->the_post(); ?>
						<tr>
							<td><?php meta('uni-class'); ?></td>
                            <td><a href="<?php the_permalink(); ?>"><?php meta('uni-name'); ?></a></td>
                            <td><?php meta('uni-country'); ?></td>
                            <td class="stat"><?php meta('uni-acceptances'); ?></td>
                            <td class="stat"><?php meta('uni-offers'); ?></td>
                            <td class="stat"><?php meta('uni-matriculations'); ?></td>
                        </tr>
                      <?php remove_filter('posts_orderby','customorderby'); ?>

					<?php	endwhile;
						wp_reset_postdata();
					?>
                    </table>

If you take a look at http://www.trevelations.com/dev/university-acceptance-profile/, without filtering any data, you’ll see that the data is ordered firstly in descending order in the Class column, then within that, ascending order is the Country column, and finally by ascending order in the University column. That’s what the customorderby function and filter achieve (before filtering).

For clarity, everything is working now except the ability to order the search results by multiple meta_keys – I can only order by a single one meta_key.

Yes, that’s where I found the injecting_custom_arg function that I put into my functions.php. It works, but only for a single meta_key. Guess I’ve got some experimenting to do.
