    8 years, 4 months ago

    I create a new post type ‘book‘. And i register new taxonomy for post type ‘book’. The name is ‘cat_book‘

    Now I want exclude category id ’30’ and ’31’ from archive-book.php

    I add this in function:

    function exclude_cat( $query ) {
	if ( !is_admin() && $query->is_main_query() ) {
		if ( is_post_type_archive( 'book' ) ) {
			$query->set( 'category__not_in', array( 30, 31 ) );
			return;
		}
	}
}
add_action('pre_get_posts','exclude_cat');

    But can’t work. Can someone help me, please! Thanks.

    the code you show is using the category taxonomy and not the custom taxonomy you created.

    Look at the code for custom taxonomies in the wp_query docs:

    Thanks Steven for your help.

    But honestly I don’t understand how to implement “Taxonomy_Parameters” into my code. Can you help me, please!

    Many thanks.

    Try this:

    function exclude_cat( $query ) {
	if ( !is_admin() && $query->is_main_query() ) {
		if ( is_post_type_archive( 'book' ) ) {
			$tax_query = $query->get( 'tax_query' ) ?: array();

			$tax_query[] = array(
				'taxonomy' => 'cat_book',
				'field'    => 'id',
				'terms'    => array( 30, 31 ),
				'operator' => 'NOT IN',
			);

			$query->set( 'tax_query', $tax_query );
		}
	}

	return $query;
}
add_action('pre_get_posts','exclude_cat');

    I wrote it blind, so make a backup of your functions file before adding this, in case I made a type-o.

    Hi there,

    This is half way to solving my problem so thank you very much for sharing.

    I can only get this code to work if I remove the <if> statements. I need them otherwise the function is applied to all pages in the site, not just the home page.

    I have a static front page configured.

    This is the code I have been trying to use:

    add_action('pre_get_posts','exclude_cat');
function exclude_cat( $query ) {
	if ( !is_admin() && $query->is_main_query() ) {
		$tax_query = $query->get( 'tax_query' ) ?: array();
		$tax_query[] = array(
			'taxonomy' => 'st_category',
			'field'    => 'id',
			'terms'    => array( 115 ),
			'operator' => 'NOT IN',
		);
		$query->set( 'tax_query', $tax_query );
	}
	return $query;
}

    I have also tried the following <if> statements with no success:

    if( $query->is_page( array( 113, 'portfolio', 'Portfolio' ) ) ) {
    if( $query->is_home() ) {
    if( $query->is_front_page() ) {

    It works perfectly without the <if> statements! What is going on?

    Please help if you can – thank you!
