是否有可能在wordpress循环通过帖子，然后如果下一篇文章不在同一类别然后做一些事情。因此，每个岗位的内环路

我需要得到cateogry或类别的职位是。

然后一些如何存储和比较，在循环中的下一个职位。

Answer 1

我的策略是为以前的类别设置一个校验数组，然后每次比较。

因此，您可以在循环中检查当前类别

例如，

//set a check array 
$previous_categories = array(); 

while ($the_query->have_posts()) { 
    $the_query->the_post(); 
    // get the categories for this post 
    $current_categories = get_the_category(); 

    // set up a temp array to change the previous_categories array when we have finished 
    $tmp_categories = array(); 

    // now iterate through the categories and see if it is in the previous post 
    if($categories){ 
     foreach($categories as $category) { 
      // do the check 
      if (in_array($category->term_id,$previous_categories)){ 
       // then its in the previous and you do your thing 
      } 

      // add the current id to the temp array 
      $tmp_categories[] = $category->term_id; 
     } 
     // now we can set for the next post 
     $previous_categories = $tmp_categories; 

    } else { 
     // there were no categories for this post so it cant match 
     // but we do need to initialise the previous_categories array 
     $previous_categories = array(); 
    } 

}
