WP_Query with custom taxonomies and post types…!

    Hi, so I’ve read up on this a lot, and I’m still having issues getting the data I need. Here’s the task…

    I have 6 custom post types, they all share one taxonomy which has many terms. On my home page I need to get the top 4 most used/popular terms for each custom post type. I’ve discovered I might be able to do with with wp_query, a little like my code (which doesn’t work, it’s ignoring the taxonomy and calling all posts from the CPT);

    $args = array(
	'post_type' => 'pt_plumbers',
	'tax_query'=>array(
		'taxonomy'=>'trade',
		'field'=>'slug',
		'term'=>'boiler-installation'
	)
);

    To fully make this work I think I will be using a second “hidden” taxonomy which is unique to each CPT, making the query feasible for each CPT (so I don’t just get the actual top 4 terms across the entire site, it must be post type specific).

    Hope that makes sense, hit me with what you’ve got while I still have some hair 😀

    Thanks!

    Hello,

    tax_query requires an array of arrays, if that makes sense!

    So, your code should probably be as follows:

    $args = array(
	'post_type' => 'pt_plumbers',
	'tax_query' => array(
		array(
			'taxonomy' => 'trade',
			'field' => 'slug',
			'term' => 'boiler-installation'
		)
	)
);

    This is described in more detail here (specifically, the “Important Note” section).

    I’ve read the codex page again, and it looks like you’re right! Sadly it still finds no posts. Just to make sure I understand this…

    – My custom taxonomy is called “trade”
    – One of my terms/categories under trade is “boiler-installation”
    – I’m querying using the slug.

    That sounds simple enough so what am I doing wrong?

    That sounds like it should be ok.

    Where abouts is this code? In a template file / in functions.php / in a plugin etc?

    Could you post all the code you’re using (perhaps at pastebin)? It might be easier to figure out the problem in context.

    The post type is made in a plugin file, but that’s all working as it should be. The query is in a template file;

    $args = array(
	'post_type' => 'pt_plumbers',
	'tax_query'=>array(
			array(
			'taxonomy'=>'trade',
			'field'=>'slug',
			'term'=> 'boiler-installation'
			)
	)
);
$plumber_tax = new WP_Query($args);
print_r($plumber_tax);
if($plumber_tax->have_posts()){
	while($plumber_tax->have_posts()){
		$plumber_tax->the_post();
			the_title();
	}
}

    Ah, looks like it might just be a small typo. In tax_query, term should be terms, like this:

    $args = array(
	'post_type' => 'pt_plumbers',
	'tax_query' => array(
		array(
			'taxonomy' => 'trade',
			'field'    => 'slug',
			'terms'    => 'boiler-installation'
		)
	)
);

    I didn’t notice at first!

    Thanks for the pointer – silly me!

    I need to figure out how to add my “hidden” taxonomy in the query now. Oh, the woes of PHP. Good fun when it goes well, despair when it doesn’t 😀
