Hmm perhaps - what seems to be the problem sir?

[Glunk]

let's see ur code

[chenGOD]

The problem is, I need the advanced search widget in the sidebar of this site: asiapacificmemo.ca to return results by most recent date.

 

Code is here:

<?php

Word. It'll take a bit to sort through but I'll try my hand at it Chen.

[mcbpete]

There's this code for an alternative API to sort by date, but I'm sure it can be bunged into that one (somewhere) (possibly) - https://swiftype.com/documentation/tutorials/dynamically_changing_sort_order_with_wordpress

[chenGOD]

Cheers both of you. Will have a shot at your solution tomorrow Pete.

[Centurix]

Wordpress has a filter called posts_orderby which you return your desired order. Registered in the same way as the posts_where. Add the following near the top of your code somewhere:

function advancedSearchWidget_searchorder($order, $query) {
	global $wpdb;
	if(!is_admin() && is_search()) // Add the filter for the most recent date first of each post
		$order = $wpdb->prefix."posts.post_date DESC";

	return $order;
}
add_filter('posts_orderby','advancedSearchWidget_searchorder');

Bear in mind I haven't tested this, the function name follows the widgets naming conventions and fairly it's straight forward. Should mention that the important part is the posts,post_date DESC, which is the actual ordering itself.

[chenGOD]

Gave your code a shot Cen, returned this error:

 

Warning: Missing argument 2 for advancedSearchWidget_searchorder() in /home/content/32/6336232/html/wp-content/plugins/advanced-search-widget/advanced-search-widget.php on line 95

 

Any ideas?

[mcbpete]

Looks like the function has two inputs ( $order and $query ) but is only using the $order bit. Complete guess but maybe change the first line to:

function advancedSearchWidget_searchorder($order) {

[Centurix]

cool, ta

[chenGOD]

Well it doesn't return an error anymore, so that's sorted.

 

I must be putting it in the wrong place in the code, cause now the first group of queries to be returned comes from the list of contributors. Then I get posts returned but also still not by any ordered date, just seems random.

 

This is the code as I have it now

function advancedSearchWidget_searchorder($order) {
	global $wpdb;
	if(!is_admin() && is_search()) // Add the filter for the most recent date first of each post
		$order = $wpdb->prefix."posts.post_date DESC";

	return $order;
}
add_filter('posts_orderby','advancedSearchWidget_searchorder');

So I guess it's just a matter of plugging in in the right place? I've set the plugin to search only tags, because the two other options are Title (not broad enough) and Content (too broad). I wish there was a way for it to search categories, but the author doesn't seem to have thought of that, and it seems like he's not actively developing it anymore.

Another alternative would of course be a different search widget...can anyone recommend one?

[Centurix]

Weird, the position doesn't matter as it's just a register of filters for Wordpress to process. Changed the prefixing to match the rest of the widget. Don't think that's going to fix the ordering.

function advancedSearchWidget_searchorder($order) {
	global $table_prefix;
	if(!is_admin() && is_search()) // Add the filter for the most recent date first of each post
		$order = $table_prefix."posts.post_date DESC";

	return $order;
}
add_filter('posts_orderby','advancedSearchWidget_searchorder');

Maybe replace post_date with post_modified, might be more accurate:

function advancedSearchWidget_searchorder($order) {
	global $table_prefix;
	if(!is_admin() && is_search()) // Add the filter for the most recent date first of each post
		$order = $table_prefix."posts.post_modified DESC";

	return $order;
}
add_filter('posts_orderby','advancedSearchWidget_searchorder');
