Php 为什么WP#u查询'；s meta_查询未筛选结果？

我在一个wordpress网站上工作，该网站利用WP_查询在tax_查询中根据歌曲的类别、标签和其他内容查找歌曲，但它也在meta_查询中分组，meta_查询（应该）根据bpm和其他元数据查找歌曲

在Wordpress的“媒体”选项卡中，管理员可以添加歌曲，并将其附加到产品，列出曲目信息，如作曲家、BPM等

所有税务查询内容（类别、标签、情绪等）都会正确地收回歌曲。但是，如果我将BPM设置为90，则会返回数据库中的每个轨迹

这是怎么回事？以下是整个搜索功能：

我应该仔细看看我在评论中发布的例子。你有

if( isset( $_POST['track-bpm'] ) and !empty( $_POST['track-bpm'] ) ) {
  $search_meta_fields[] = $_POST['track-bpm'];

  $track_q['meta_query'][] =  array(
      'meta_key'    => '_track_bpm',
      'meta_value'  => $_POST['track-bpm'],
      'compare'     => '='
  );
}

数组的键是错误的。它们应该是

键

和

值

，而不是

元键

和

元值

。这应该起作用：

if( isset( $_POST['track-bpm'] ) and !empty( $_POST['track-bpm'] ) ) {
  $search_meta_fields[] = $_POST['track-bpm'];

  $track_q['meta_query'][] =  array(
      'key'      => '_track_bpm',
      'value'    => $_POST['track-bpm'],
      'compare'  => '='
  );
}

您的其他

meta\u查询

条件可能也是如此。

我可能遗漏了一些内容，但我可以看到正在填充

$search\u tax\u字段

和

$search\u meta\u字段

，但我看不到它们正在查询中使用。输入是什么？”90'或'90--'？@SidGBF50输入是'90'@Hobo它们用于计数我想（我继承了这段代码）如果添加

'type'=>'numeric'

之类的内容会发生什么？

if( isset( $_POST['track-bpm'] ) and !empty( $_POST['track-bpm'] ) ) {
  $search_meta_fields[] = $_POST['track-bpm'];

  $track_q['meta_query'][] =  array(
      'key'      => '_track_bpm',
      'value'    => $_POST['track-bpm'],
      'compare'  => '='
  );
}
