你好，开发专家，你能看看吗，我把什么搞砸了？
function mysite_filter_function(){
//groups checkboxes
if( $groups = get_terms( array( \'taxonomy\' => \'category\' ) ) ) :
$groups_terms = array();
foreach( $groups as $group ) {
if( isset( $_POST[\'group_\' . $group->term_id ] ) && $_POST[\'group_\' . $group->term_id] == \'on\' )
$groups_terms[] = $group->slug;
}
endif;
$tax_query = array( \'relation\' => \'AND\' );
if ( ! empty( $groups_terms ) ) {
$tax_query[] = array(
\'taxonomy\' => \'category\',
\'field\' => \'slug\',
\'terms\' => $groups_terms,
);
}
$args = array(
\'orderby\' => \'date\',
\'post_type\' => \'course\',
\'posts_per_page\' => -1,
\'tax_query\' => $tax_query,
);
$query = new WP_Query( $args );
if( $query->have_posts() ) :
while( $query->have_posts() ): $query->the_post();
// echo \'<h2>\' . $query->post->post_title . \'</h2>\';
// get_template_part( \'customcourse\');
?>
<div class="col-md-4">

wp_reset_postdata();

@如果您只是在代码中保留了一行代码，而如果选择了某个类别，则需要对其进行更改，那么您会很高兴。
$args = array(
\'orderby\' => \'date\',
\'post_type\' => \'course\',
\'posts_per_page\' => -1,
\'tax_query\' => $tax_query,
);
这个有
\'posts_per_page\' => -1 需要更改为
\'posts_per_page\' => 9, \'paged\' => $paged 将分类的ajax调用作为分页查询。
if ( ! empty( $groups_terms ) ) {
$paged = 2; //This needs to be the Paged Request Number.
$args = array(
\'orderby\' => \'date\',
\'post_type\' => \'course\',
\'posts_per_page\' => 9,
\'paged\' => $paged,
\'tax_query\' => $tax_query
);
}
else
{
$args = array(
\'orderby\' => \'date\',
\'post_type\' => \'course\',
\'posts_per_page\' => -1,
);
}
