Question

我正在运行一个使用wpml的wordpress网站，这会给我一些问题，试图对我在翻译过的帖子中的标签运行查询。

所以我想要做的是一个小小的黑客，这将允许我查询所有帖子，并使用wordpresses函数get_the_tags（）;

找到具有特定标签的帖子

我正在尝试使用in_array，它似乎不适用于wordpress输出的多维数组，这里是来自print_r（）的数组;

这是我的代码我只希望它找到名称为welsh1的数组，这是数组中的最后一个。

  // Global calls to the database
  global $wpdb;

  // Runs a query to get all results from the wp_posts table
  $all = $wpdb->get_results( "SELECT * FROM wp_posts" );

  // loops through each one   
  foreach($all as $v){

      $tags = get_the_tags($v->ID);

      if (in_array('welsh1', $tags)) {
        echo "'ph' was found\n";
      }

      echo "<pre>";
      print_r($tags);
      echo "</pre>";
  }

$ tags是一个对象数组，而不是多维数组。

以下代码应标识字符串welsh1

foreach($tags as $tag){
  if ($tag->name == "welsh1" || $tag->slug == "welsh1"){
     echo "'ph' was found\n";
     break;//this line makes the foreach loop end after first success.
  }
}

查找具有特定值的数组多维数组wordpress in_array
