Exclude current post when getting related post on custom post type and taxonomy

Question

The below will return the other post in the same category but it will also return the current post too.

Is there a way to exclude the current post from the query?

$args = array(
'post_type'     => 'custom_post_type',
'tax_query'     => array(
    array(
        'taxonomy'  => 'custom_taxo',
        'field'     => 'term_id',
        'terms'      => array(1,2,5),
        'operator'  => 'IN'
    )
)
);

$query = new WP_Query( $args );

Answer 1

Simply add

'post__not_in' => [get_queried_object_id()],

to your array of query arguments. get_queried_object_id() will return the post ID of the currently viewed single post, and post__not_in will skip the posts whos ID's was passed as an array to the parameter

Answer 2

You can use post__not_in with the get_the_ID of the post in this case your code should be like this :

                $args = array(
                            'post_type'     => 'custom_post_type',
                            'tax_query'     => array(
                                array(
                                    'taxonomy'  => 'custom_taxo',
                                    'field'     => 'term_id',
                                    'terms'      => array(1,2,5),
                                    'operator'  => 'IN'
                                )
                            ),
                        'post__not_in' => array (get_the_ID()), 

                    );

                $query = new WP_Query( $args );

Note: The value has to be an array 'post__not_in' => array (get_the_ID())
