To display all the categories name with checkbox from custom taxonomy called ct_category I have the following code:
$terms = get_terms('ct_category');
foreach ( $terms as $term ) {
echo '<li class='.$term->term_id.'><label > <input class="taxonomy_category" type="checkbox" name="taxonomy_category['.$term->term_id.']" value ="'.$term->term_id.'" />'.$term->name.'</label ></li>';
}
I would like to display content only from checked categories. I tried following that didn't work:
$args = array(
'post_type' => 'cpt',
'tax_query' => array(
array(
'taxonomy' => $ct_category,
'field' => 'term_id',
'terms' => $_POST['taxonomy_category']
)
)
);
$loop = new WP_Query( $args );
I can guess that the issue is in 'terms' => $_POST['taxonomy_category']. If name attribute taxonomy_category['.$term->term_id.'] can be displayed as array in 'terms' =>, the issue would be fixed. Spent plenty of times searching google but couldn't find any solution.

Reset to default 2If $taxonomy_category is already an array, then:
'terms' => array($taxonomy_category)
should just be:
'terms' => $taxonomy_category
where $taxonomy_category is equal to whatever was submitted from your form as $_POST['taxonomy_category'] or $_GET['taxonomy_category']
It is an advanced question that would take me time to debug. However I believe the 'id' value for 'field' is not right. From the documentation,
field (string) - Select taxonomy term by. Possible values are 'term_id', 'name', 'slug' or 'term_taxonomy_id'. Default value is 'term_id'.
I think you want term_id...
Try 2:
Click into your custom taxonomy called 'ct_category' and get the slug for your taxonomy. You do this in the backend probably a submenu of a custom post type.
set up your tax_query
$tax_args = array(
array('taxonomy' => 'ct_category',
'field' => 'slug',
'terms' => 'term_slug',
'operator' => 'IN')
);
Set up your args
$args = array('post_type' => 'cpt',
'post_status' => 'publish',
'posts_per_page'=>-1,
'tax_query'=>$tax_args);
$query = new WP_Query($args);
See if you can get that working...then work on getting it to work with term_id.
