我试图用这个结构（whit this content（））显示一个类别及其子类别：
- Category Father title
- Children title
- Other children title
- Category Father title
- ....
但是用这个代码
$catH = array(11);
$query = array("cat"=>42,"order"=>"ASC","posts_per_page"=>-1,"category__not_in"=>$catH);
$obj = new WP_Query($query);
if ($obj->have_posts()){
while($obj->have_posts()){
$obj->the_post();
$slug = get_the_tags();
the_title();
echo "<br/>";
$queryH = array("cat"=>13,"order"=>"ASC","posts_per_page"=>-1,"tag__in"=>$slug);
$objH = new WP_Query($queryH);
if ($objH->have_posts()){
while($objH->have_posts()){
$objH->the_post();
the_title();
echo "<br/>";
}
}
}
wp_reset_postdata();
}
结果如下：
类别父标题
儿童标题
其他孩子的标题如何修复？
最合适的回答,由SO网友:T.Todua 整理而成
try like this:
if ($obj->have_posts()){
while($obj->have_posts()){
$obj->the_post();
$slug = get_the_tags();
$obj->the_title();
echo "<br/>";
$queryH = array("cat"=>13,"order"=>"ASC","posts_per_page"=>-1,"tag__in"=>$slug);
$objH = new WP_Query($queryH);
if ($objH->have_posts()){
while($objH->have_posts()){
$objH->the_post();
$objH->the_title();
echo "<br/>";
}
}
}
}
