tax_qeury在wordpress中不起作用。怎么解决（） _WordPress开发

我制作了一个页面模板, 可以在其中过滤一些帖子。如果你执行正常的WP_Query, 则一切正常。但是, 如果我使用tax_query, 它不会显示任何帖子。
为了注册帖子类型和分类法, 我使用了插件” cptui” 。
常规WP_Query请求：

$query = new WP_Query(array( 'post_type' => $post-> post_name, 'post_status' => 'publish', 'posts_per_page' => 6, 'paged' => $paged, )); if(!$_POST) { //If not filtered ... then show all if($query-> have_posts()): while ($query-> have_posts()) : $query-> the_post(); echo "< a href='".get_post_permalink()."'> < div style='box-shadow: 0 0 15px 0 rgba(0, 0, 0, .05); padding: 50px; width: 100%; margin: 5px; '> "; echo "< h5> " . $query-> post-> post_title . "< /h5> "; echo "< p> " . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))-> name . "< /p> "; echo "< /div> < /a> "; endwhile; endif; }

我读了其他文章, 他们说我可以使用php echo $ GLOBALS [‘ query’ ]-> request; 看看什么是mysql查询。
我的查询是：SELECT SQL_CALC_FOUND_ROWS wp_posts.ID from wp_posts WHERE 1 = 1 AND wp_posts.post_type =’ vacature’ AND(((wp_posts.post_status =’ publish’ ))ORDER BY wp_posts.post_date DESC LIMIT 6, 6
现在是带有tax_query的请求。 tax_query WP_Query请求：

$query = new WP_Query(array( 'post_type' => $post-> post_name, 'post_status' => 'publish', 'posts_per_page' => 6, 'paged' => $paged, 'tax_query' => array( array( 'taxonomy' => 'provincie', 'field'=> 'slug', 'terms'=> 'noord-brabant', 'include_children'=> 0 ), ), )); if(!$_POST) { //If not filtered ... then show all if($query-> have_posts()): while ($query-> have_posts()) : $query-> the_post(); echo "< a href='".get_post_permalink()."'> < div style='box-shadow: 0 0 15px 0 rgba(0, 0, 0, .05); padding: 50px; width: 100%; margin: 5px; '> "; echo "< h5> " . $query-> post-> post_title . "< /h5> "; echo "< p> " . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))-> name . "< /p> "; echo "< /div> < /a> "; endwhile; endif; }

我现在得到的查询是：SELECT SQL_CALC_FOUND_ROWS wp_posts.ID from wp_posts LEFT JOIN wp_term_relationships ON(wp_posts.ID = wp_term_relationships.object_id)WHERE 1 = 1 AND(wp_term_relationships.term_taxonomy_id IN)(3) ((wp_posts.post_status =’ publish’ ))GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 6、6, 但我没有发回任何帖子。
你知道对此有什么解决方案吗？
模板的完整代码：

< div id="page-< ?php the_ID(); ?> " < ?php post_class(); ?> > < ?php the_content(); ?> < ?php global $post; $paged = ( get_query_var('paged')) ? get_query_var('paged') : 1; $query = new WP_Query(array( 'post_type' => $post-> post_name, 'post_status' => 'publish', 'posts_per_page' => 6, 'paged' => $paged, 'tax_query' => array( array( 'taxonomy' => 'provincie', 'field' => 'slug', 'terms' => array( 'noord-brabant') ) ) )); // echo $GLOBALS['query']-> request; if(!$_POST) { //If not filtered ... then show all if($query-> have_posts()): while ($query-> have_posts()) : $query-> the_post(); echo "< a href='".get_post_permalink()."'> < div style='box-shadow: 0 0 15px 0 rgba(0, 0, 0, .05); padding: 50px; width: 100%; margin: 5px; '> "; echo "< h5> " . $query-> post-> post_title . "< /h5> "; echo "< p> " . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))-> name . "< /p> "; echo "< /div> < /a> "; endwhile; endif; } else { //now its filtered $null = true; if($query-> have_posts()): while ($query-> have_posts()) : $query-> the_post(); $filterconditions = []; //hier komen alle filtercondities in$keys = array_keys($_POST); foreach($keys as $key) { if($_POST[$key] == "on") { $filter = explode("_", $key); $field = $filter[0]; $filter = $filter[1]; $taxonomy = get_field( $field ); $term = get_term_by('term_id', $taxonomy, $field); array_push($filterconditions, '"' . $filter . '"' . '==' . '"' . $term-> name . '"'); } }; $filterconditions = implode('& & ', $filterconditions); // echo $filterconditions; if(eval("return $filterconditions; ")) { $null = false; echo "< a href='".get_post_permalink()."'> < div style='box-shadow: 0 0 15px 0 rgba(0, 0, 0, .05); padding: 50px; width: 100%; margin: 5px; '> "; echo "< h5> " . $query-> post-> post_title . "< /h5> "; echo "< p> " . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))-> name . "< /p> "; echo "< /div> < /a> "; } endwhile; endif; if($null) { echo "Sorry, er zijn geen vacatures gevonden met deze filters"; } }$total_pages = $query-> max_num_pages; if ($total_pages > 1 & & !$null) { $current_page = max(1, get_query_var('paged')); echo paginate_links(array( 'base' => get_pagenum_link(1) . '%_%', 'format' => '/page/%#%', 'current' => $current_page, 'total' => $total_pages, 'prev_text'=> __('? prev'), 'next_text'=> __('next ?'), )); } wp_reset_query(); ?> < /div>

$args=array( 'post_type' => 'your_post_type', 'post_status' => 'publish', 'orderby' => 'title', 'order' => 'DESC', 'posts_per_page' => 6, 'tax_query' => array( array( 'taxonomy' => 'provincie', 'field' => 'slug', 'terms' => array( 'noord-brabant') ) ) ); $result = new WP_Query( $args ); // The Loop if ( $result-> have_posts() ){ while ( $result-> have_posts() ) { $result-> the_post(); // this is your loop}} else { // nothing }

可以尝试上面的代码
#2你可以使用以下代码获取简单的自定义帖子类型列表：

$args = array( 'post_type' => 'services', 'post_status' => 'publish', 'posts_per_page' => 6, 'orderby’ => 'title', 'order’ => 'ASC', ); $loop = new WP_Query( $args ); while ( $loop-> have_posts() ) : $loop-> the_post(); print the_title(); the_excerpt(); endwhile; wp_reset_postdata();

放置自定义帖子类型名称以检索帖子并根据需要更改while循环
#3【tax_qeury在wordpress中不起作用。怎么解决（）】好的, 你可以使用get post方法代替WP Query：

$posts_array = get_posts( array( 'posts_per_page' => 6, 'post_type' => $post-> post_name, // Get POST TYPE FROM $GLOBAL POST 'tax_query' => array( array( 'taxonomy' => 'provincie', 'field' => 'slug', 'terms' => 'noord-brabant', ) ) ) );
