I'm trying to add a meta_query to some of my post types (post, eventos, agenda).
I had some experience using pre_get_posts, I guessed i would just hook on it and check that whenever the post type was in the array, I would add the meta.
I'm not able to always get the post type thou, the situation in details:
Loading Front page (static page defined), Contains 3 queries inside: 1 for posts (used query_posts() and only defined posts_per_page, since post type "post" is default). 2 other queries are get_posts() since they wont require pagination.
Right now I'm just hookin into the action and dumping the provided object:
function my_pre_get($query) {
var_dump($query);
}
add_action( 'pre_get_posts', 'my_pre_get');
What happens is, the action runs at every single query performed for the page load (main query, my query_posts and the get_posts) But on main query I get all empty values inside the object. On query_posts I only get the value for pagination I've set. On the get_posts I get the post types.
Right now I'm not sure what route to take... I can try to implement some complex checking to find out the type of page I'm on and then assume post_type is post, but this seems like a terrible inefficient and troublesome idea.
Is there an alternative way to always get the post type when a query is about to run and modify it?
I have also tried hook into parse_query, but same results. :/
----edit As it was requested, the front page template code (thou i don't think that's helpful for the topic at all):
<?php /*** Template Name: Front Page */ ?>
<!doctype html>
<html <?php language_attributes(); ?> >
<head>
<?php wp_head(); ?>
</head>
<body>
<?php wp_footer(); ?>
</body>
The action is added inside functions.php which is pretty much whats above already.
I did a deep loop into class-wp-query.php and that's the natural behavior of pre_get_posts.
"Default" query parameters, like post type, default items_per_page... etc, are all set in a really complex "IF" sets., after the pre_get_posts actions.
So, in a 'default' front end query, "post_type" will never be available as a query_var, no matter which hook is used. It is needed to go trough workarounds to find out if the current post type is 'post' in a main_query.
In a clear answer to my question: No
