合并相同标题下的条款,除非new =创建新的标题Wordpress查询

Question

在'foreach'循环期间,如果检测到相同的术语,则只添加页面链接,否则在单个wp_query期间添加术语名称和页面链接？

例如:

1. 标题1 Apple Pie
2. 标题1樱桃馅饼
3. 标题2火腿馅饼
4. 标题3山羊派
5. 标题1面条蛋糕

应该成为:

1. • 标题1
     • 苹果派,
     • 樱桃派,
     • 面条蛋糕
2. • 标题2
     • 火腿馅饼
3. • 标题3
     • 山羊馅饼

Answer 1

我希望这有帮助。

$titles = array('Title 1 Apple Pie','Title 1 Cherry Pie','Title 2 Ham Pie','Title 3 Goat Pie');
$list = '<ol>';
foreach ($titles as $value) {
$subtitle = substr($value, 0, 7);
if(!strpos($final,$subtitle )){
   $list .= '<li>' . $value . '</li>' ;
}  else {
    $pos = stripos($list, $subtitle);
    $left_string = substr($list,0, $pos);
    $substring = substr($list, $pos);
    $next_pos = stripos($substring, '<');
    $right_string = substr($substring, $next_pos);
    $current = substr($substring, 8, $next_pos);
    $current = rtrim($current, '</li>');
    $list = '';
    $last = $current . ' '. substr($value, 8);
    $list = $left_string .' '. $subtitle.' '. $last . ' '.      $right_string;
      }
  }
    $final .= '</ol>';
     echo $final;

输出。
