How to order posts by two meta values

October 15, 2013 at 4:20 pm

By default, WordPress allows you to sort results of a query by one meta value, but what if you need to sort results by two meta values (For example date and time)? Here ‘s a working example.

Paste the code below in your template file where you need to sort the results of the query.

<?php 

$query = "SELECT wposts.*, wpostmeta1.*, wpostmeta2.* 
FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta1, $wpdb->postmeta wpostmeta2
WHERE wposts.ID = wpostmeta1.post_id
AND wposts.ID = wpostmeta2.post_id
AND wpostmeta1.meta_key = 'date'
AND wpostmeta2.meta_key = 'time'
ORDER BY wpostmeta1.meta_value ASC,
         wpostmeta2.meta_value ASC";

$results = $wpdb->get_results($query);

foreach ( $results as $result ) {
         //output results as desired
} ?>

Please note that this query is given as an example and might need to be adapted to fit your specific needs. If you need help at a cheap rate, contact WPCAT.

	$description = get_bloginfo('description', 'display');
	$pagedata = get_post($post->ID);
	if (is_singular()) {
		if (!empty($seo_desc)) {
			$content = $seo_desc;
		} else if (!empty($pagedata)) {
			$content = apply_filters('the_excerpt_rss', $pagedata->post_content);
			$content = substr(trim(strip_tags($content)), 0, 155);
			$content = preg_replace('#\n#', ' ', $content);
			$content = preg_replace('#\s{2,}#', ' ', $content);

		} 
	} else {
		$content = $description;	
	}
	$output .= '<meta name="description" content="' . esc_attr($content) . '">' . "\n";

	// keywords
	$keys = get_post_meta($post->ID, 'mm_seo_keywords', true);
	$cats = get_the_category();
	$tags = get_the_tags();
	if (empty($keys)) {
		if (!empty($cats)) foreach($cats as $cat) $keys .= $cat->name . ', ';
		if (!empty($tags)) foreach($tags as $tag) $keys .= $tag->name . ', ';
		$keys .= $default_keywords;
	}
	$output .= "\t\t" . '<meta name="keywords" content="' . esc_attr($keys) . '">' . "\n";

	// robots
	if (is_category() || is_tag()) {
		$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
		if ($paged > 1) {
			$output .=  "\t\t" . '<meta name="robots" content="noindex,follow">' . "\n";
		} else {
			$output .=  "\t\t" . '<meta name="robots" content="index,follow">' . "\n";
		}
	} else if (is_home() || is_singular()) {
		$output .=  "\t\t" . '<meta name="robots" content="index,follow">' . "\n";
	} else {
		$output .= "\t\t" . '<meta name="robots" content="noindex,follow">' . "\n";
	}

	// title
	$title_custom = get_post_meta($post->ID, 'mm_seo_title', true);
	$url = ltrim(esc_url($_SERVER['REQUEST_URI']), '/');
	$name = get_bloginfo('name', 'display');
	$title = trim(wp_title('', false));
	$cat = single_cat_title('', false);
	$tag = single_tag_title('', false);
	$search = get_search_query();

	if (!empty($title_custom)) $title = $title_custom;
	if ($paged >= 2 || $page >= 2) $page_number = ' | ' . sprintf('Page %s', max($paged, $page));
	else $page_number = '';

	if (is_home() || is_front_page()) $seo_title = $name . ' | ' . $description;
	elseif (is_singular())            $seo_title = $title . ' | ' . $name;
	elseif (is_tag())                 $seo_title = 'Tag Archive: ' . $tag . ' | ' . $name;
	elseif (is_category())            $seo_title = 'Category Archive: ' . $cat . ' | ' . $name;
	elseif (is_archive())             $seo_title = 'Archive: ' . $title . ' | ' . $name;
	elseif (is_search())              $seo_title = 'Search: ' . $search . ' | ' . $name;
	elseif (is_404())                 $seo_title = '404 - Not Found: ' . $url . ' | ' . $name;
	else                              $seo_title = $name . ' | ' . $description;

	$output .= "\t\t" . '<title>' . esc_attr($seo_title . $page_number) . '</title>' . "\n";

	return $output;
}

Once done, replace the $default_keywords (line 3) with your own and add the following code into your header.php file:

<?php echo basic_wp_seo(); ?>

Then, don’t forget to check the source of your pages and fine tune the code if needed.

   }
}
