我有一个带有复选框的配置文件字段，用户可以在其中检查他们的“兴趣”。我想通过一个包含用户兴趣的搜索字符串来定制活动提要。遵循此处的搜索词方法（带有“nap”的示例）：http://premium.wpmudev.org/blog/how-to-customize-the-buddypress-activity-loop/

我在活动循环的顶部有这个。php：

<?php
  $activity_search_terms = "&search_terms=";
  if ( $interests = xprofile_get_field_data( \'Interests\', bp_loggedin_user_id() ) ) {
    foreach ( $interests as $interest ) {
      $activity_search_terms .= strtolower($interest) . "+";
    }
  }
?>

<?php if ( bp_has_activities( bp_ajax_querystring( \'activity\' ) . rtrim($activity_search_terms, \'+\') ) ) : ?>

如果活动搜索使用OR查询而不是AND查询，这将非常有效。现在，如果用户点击“瑜伽”和“交叉健身”作为兴趣，那么活动提要将只包含这两个术语，而不是其中任何一个。

我安装了Relevanssi并将其设置为或query，但它似乎不适用于活动搜索。是否有方法强制或查询bp_has_activities?

使用WP 4.1和BP 2.1.1

UPDATE:我通过修改BuddyPress使其工作bp-activity\\bp-activity-classes.php 在L.346左右为每个搜索词写一个类似的语句。如果你能告诉我如何在插件中实现同样的功能（无需避免$wpdb->prepare), 赏金是你的！

// Searching
if ( $search_terms ) {
  $search_terms_array = explode(\' \', $search_terms);
  // WAS: $search_terms_like = \'%\' . bp_esc_like( $search_terms ) . \'%\';

  $search_terms_like = \'\';
  foreach( $search_terms_array as $term)
    $search_terms_like .= \'a.content LIKE \\\'%\' . bp_esc_like( $term ) . \'%\\\' OR \';
  $where_conditions[\'search_sql\'] = rtrim($search_terms_like, \' OR \');
  // WAS: $where_conditions[\'search_sql\'] = $wpdb->prepare( \'a.content LIKE %s\', $search_terms_like);
}

// Customize activity filters
add_filter( \'bp_activity_get_where_conditions\', \'my_activity_filters\', 1, 1 );
function my_activity_filters($search) {

  $search_terms = explode( "%", $search["search_sql"] )[1];
  $search_terms_array = explode(\' \', $search_terms);
  $search_terms_like = \'\';

  if( !empty( $search_terms_array ) ) {           // Searching for something specific
    foreach( $search_terms_array as $term)
      $search_terms_like .= \'a.content LIKE \\\'%\' . bp_esc_like( $term ) . \'%\\\' OR \';
    $my_search = rtrim($search_terms_like, \' OR \');
  } #else if(  ) {                       // Not searching for something specific, but user has interests, show those

  #} else {                              // Not searching for something specific, and user has no interests, show everything

  #}

  $search["search_sql"] = $my_search;

  return $search;

  #echo "<hr>";
  #echo "<strong>Search terms:</strong> $search_terms<br><br>";
  #echo "<strong>New search terms:</strong> $my_search<br><br>";
  #echo "<hr>";
}

$where_conditions = apply_filters( \'bp_activity_get_where_conditions\', $where_conditions, $r, $select_sql, $from_sql, $join_sql );
