关于 drupal 7 - views 3.0 API，我已经配置了一个视图（来自 UI）以从自定义内容类型和它显示 id 的字段之一中提取数据。我想创建一个连接（我希望以编程方式）到我的自定义表，并显示映射到视图中 id 的文本。我遇到的问题是如何找出将其加入哪个表和字段？在我的内容类型中，我创建了 field_game 字段。我的自定义表有 gameid 作为主键。

也许是这样的？

$data['MYCUSTOMTABLE']['table']['join'] = array(
// Index this array by the table name to which this table refers.
// 'left_field' is the primary key in the referenced table.
// 'field' is the foreign key in this table.
'node' => array(
  'left_table' => '??????'
  'left_field' => 'field_game', 
  'field' => 'gameid',
),
);

我搜索了高低，但没有什么能真正接近。任何帮助表示赞赏。

我在寻找类似问题时发现了这篇文章。但我已经破解了你的问题。

我把它放在 hook_views_query_alter($view, $query) 中：

if ($view->name == "kompasses") {

$ga_join = new views_join();
$ga_join->table = 'field_data_group_audience';
$ga_join->field = 'entity_id';
$ga_join->left_table = 'node';
$ga_join->left_field = 'nid';
$ga_join->type = 'inner';

$query->add_relationship('audience_node', $ga_join, 'node', null);
}

这里要加入的表是：field_data_group_audience 和基表（来自名为“kompasses”的现有视图）。Audience_node 将是连接的表别名。

您已经接近了，但请检查一下：Views 在模块代码中提供了有关如何执行此操作的文档。查看views/docs/views.api.php 并阅读！

http://drupalcontrib.org/api/drupal/contributions%21views%21views.api.php/7是那里的源代码，充满了有用的评论（在底部查看源代码）。

基本上你需要实现 hook_views_data_alter 来告诉 Views 你的表。这将允许您加入。要显示连接字段，您需要在传递给 hook_views_data_alter 的数组中设置正确的处理程序。查看views.api.php中的第343行

<?php
// This table references the {node} table. The declaration below creates an
// 'implicit' relationship to the node table, so that when 'node' is the base
// table, the fields are automatically available.
$data['example_table']['table']['join'] = array(
  // Index this array by the table name to which this table refers.
  // 'left_field' is the primary key in the referenced table.
  // 'field' is the foreign key in this table.
  'node' => array(
    'left_field' => 'nid',
    'field' => 'nid',
  ),
);

// Next, describe each of the individual fields in this table to Views. This
// is done by describing $data['example_table']['FIELD_NAME']. This part of
// the array may then have further entries:
//   - title: The label for the table field, as presented in Views.
//   - help: The description text for the table field.
//   - relation: A description of any relation handler for the table field.
//   - field: A description of any field handler for the table field.
//   - sort: A description of any sort handler for the table field.
//   - filter: A description of any filter handler for the table field.
//   - argument: A description of any argument handler for the table field.
//   - area: A description of any handler for adding content to header,
//     footer or as no result behaviour.
//
// The handler descriptions are described with examples below.

// Node ID table field.
$data['example_table']['nid'] = array(
  'title' => t('Example content'),
  'help' => t('Some example content that references a node.'),
  // The nid is a foreign key to the {node} table. This allows us to (easily)
  // add a relationship handler for this table field, making all the table
  // fields for the related node available.
  'relationship' => array(
    'base' => 'node', // The name of the table to join with
    'field' => 'nid', // The name of the field to join with
    'handler' => 'views_handler_relationship',
    'label' => t('Example node'),
  ),
);
