Question

我想要做的是使用Drupal 7，而Location模块是将节点位置继承或默认为用户位置。原因是我只希望用户编辑一个位置（在他们的个人资料上）并在该用户创建的所有节点上显示。有人可以帮忙吗？

编辑：

我找到了这个模块，我试图让Latitide和Longitude工作（正如其他人一样），但是父案例'locpick'让我感到困惑，我无法理解这一点。

<?php

function location_alter($argument){
$location_alter = array();
global $user;
$uid = $user->uid;
$location_alter = user_load($uid);
$location_alter = $location_alter->location;
return $location_alter[$argument];
}

根据您打算如何使用此结果，您甚至可能不需要保存节点的位置。即，如果要访问视图中的位置数据，则可以使用关系来访问节点作者的位置数据，即使位置数据可能根本不保存在节点上。但是，这样做意味着视图中的节点将始终与作者的当前位置相关联，而不是他们在创建节点时设置的位置。

如果您确实要将其保存在节点上，则需要创建自定义模块。您可能希望调用hook_form_alter隐藏节点编辑表单上的位置字段，并hook_node_presave将用户的位置值复制到节点的位置值。

从用户位置继承节点位置
