php - 使用实体字段查询搜索多个字段的最佳方式？

Question

使用实体字段查询搜索多个字段的最佳方式是什么？我有一个名为“项目”的内容类型，其中包含“项目经理”和“开发人员”的自定义字段，它们是对用户的引用，并且我试图在每个用户的个人资料上显示与给定用户关联的项目列表。

这是我到目前为止所拥有的:

<?php
  // Print all projects associated with this user
  $profile = user_load(arg(1));
  // Check database for reference to this user in pm field
  $query = new EntityFieldQuery();
  $result = $query->entityCondition('entity_type', 'node')
          ->entityCondition('bundle', 'project')
          ->propertyCondition('status', 1)
          ->fieldCondition('<insert multiple fields here..?>', 'target_id', $profile->uid, '=')
          ->execute();


  if (!empty($result['node'])) {
    $nids = array_keys($result['node']);
    $nodes = node_load_multiple(array_keys($result['node']));
    echo "<b>User's projects:<br></b>";
  }
  // display projects
  foreach ($nodes as &$node) {
    $targetPath = "content/";
    $targetPath .= str_replace(' ', '-', $node->title);
    $targetPath = 'http://'.$_SERVER['HTTP_HOST'].base_path().drupal_get_path_alias($targetPath, $path_language = '');
    echo "<a href='$targetPath'>$node->title</a><br>";
  }

?>

您似乎需要根据 [field_1] 或 [field_2] 值加载用户。

<?php
    // Print all projects associated with this user
    $profile = user_load(arg(1));
    // Check database for reference to this user in pm field
    $query = new EntityFieldQuery();
    $result_1 = $query->entityCondition('entity_type', 'node')
        ->entityCondition('bundle', 'project')
        ->propertyCondition('status', 1)
        ->fieldCondition('field_1', 'target_id', $profile->uid, '=')
        ->execute();

    $query = new EntityFieldQuery();
    $result_2 = $query->entityCondition('entity_type', 'node')
        ->entityCondition('bundle', 'project')
        ->propertyCondition('status', 1)
        ->fieldCondition('field_2', 'target_id', $profile->uid, '=')
        ->execute();

    $results = array();

    // 1st Set
    if (!empty($result_1['node'])) {
        $results = array_keys($result_1['node']);
    }
    // 2nd Set
    if (!empty($result_2['node'])) {
        $results += array_keys($result_2['node']);
    }

    if (count($results)) {
            $nodes = node_load_multiple($results);
            echo "<b>User's projects:<br></b>";

            // display projects
            foreach ($nodes as &$node) {
                $targetPath = "content/";
                $targetPath .= str_replace(' ', '-', $node->title);
                $targetPath = 'http://'.$_SERVER['HTTP_HOST'].base_path().drupal_get_path_alias($targetPath, $path_language = '');
                echo "<a href='$targetPath'>$node->title</a><br>";
            }
    }
?>

另外，请记住使用 Drupal 7 函数，例如 l() 和 t()。

而不是:

echo "<a href='$targetPath'>$node->title</a><br>";

写:

echo l($node->title, $targetPath)."<br>";

你会感到惊讶的。 :)
