Drupal的6次2：设置日期参数 [英] Drupal 6 Views 2: Setting Date Arguments

问题描述

传递UID作为参数正常工作与此code：

  $较量= views_get_view_result（'结果'，'PAGE_1，阵列（$用户可＆GT; UID））;
 

在views_get_view_result重点线，设置参数是：

  $视图 - ＆GT; set_arguments（$参数）;
 

但是关于传递日期范围是什么？

另外，如果事情被指定为在视图上的过滤器，是有办法prorammatically改变它？

  views_get_view_result：/ **
*调查一个视图的结果。
*从Drupal.org。
*
* @参数字符串$视图名
*视图的名称从检索数据。
* @参数字符串$ display_id
*显示器ID。对有问题的视图编辑页面，你会发现
*在控制区的左侧显示的列表。 默认值
*将在该列表的顶部。将光标悬停的名字
*显示您要使用。这样的URL将出现在状态栏上的
*浏览器。这通常是在窗口的底部，在铬。
*＃后的意见，制表一切都显示ID，例如PAGE_1。
* @参数数组的$ args
*参数数组。 （没有钥匙，只是参数）
* @返回
*阵
*包含每个视图项的对象的数组。
*字符串
*如果没有找到该视图被返回的消息。

功能views_get_view_result（$视图名，$ display_id = NULL，的$ args = NULL）{
  $视图= views_get_view（$视图名）;
  如果（is_object（$视图））{
    如果（is_array（$参数））{
      $视图 - ＆GT; set_arguments（$参数）;
    }
    如果（IS_STRING（$ display_id））{
      $视图 - ＆GT; set_display（$ display_id）;
    }
    其他{
      $视图 - ＆GT; init_display（）;
    }
    $视图 - ＆GT; pre_execute（）;
    $视图 - ＆GT;执行（）;
/ *打印＆LT; pre＆GT; $视图名：$ display_id
    的print_r（get_class_method（0函数$视图））; * /
    返回$视图 - ＆GT;的结果;
  }
  其他{
    返回T（'查看％视图名没有找到。，阵列（％视图名'=＆GT; $视图名））;
  }
}
 

解决方案

对于通过数据范围，并给予张贴的函数定义，你可以传递日期范围为，只有当该视图会接受它们作为参数。我不是100％肯定，但据我所知日期范围只能被定义为过滤器，不作为参数，从而导致你的第二个问题：

编程改变看法的过滤器设置是可能的，但有点凌乱，考虑到相当复杂的视图对象/数组混搭结构。在上面贴的功能，第一行是

  $视图= views_get_view（视图名$）;
 

之后，$视图包含整个视图对象。该过滤器设置每个显示器定义的，所以假设你有一个观点，只有一个默认显示，你会在

找到过滤器设置

  $视图 - ＆GT;显示['默认']  - ＆GT; display_options ['过滤器']
 

（注意对象/数组符号组合 - 显示器的类型views_display的包含对象）

过滤器数组包含过滤器每一个条目，以根据不同的过滤器类型不同的元素。你的目的，我建议创建一个虚拟视图只有你感兴趣的过滤器，以preconfigured /硬codeD值。使用调试器（或的var_dump / 的print_r ），然后你可以看看视图创建后滤波器阵列。从你找到那里，你应该能够推断出如何注入您的自定义日期范围。

免责声明：像这样的观点四处是有点讨厌，而不是有效的，但它的作品。作为然而，我还没有发现Views2的简明文档可以解释在一条直线前进的道路内脏，因为我找到的官方的API文档有点欠缺就从code中的用法。 （当然，这很可能只是我是愚蠢;）

Passing uid as an argument works fine with this code:

$bouts = views_get_view_result('Results', 'page_1', array($user->uid));

The key line in views_get_view_result that sets arguments is:

$view->set_arguments($args);

But what about passing date ranges?

Also, if something is specified as a filter on a view, is there a way to prorammatically alter it?

views_get_view_result:

/**
* Investigate the result of a view.
* from Drupal.org. 
*
* @param string $viewname
*      The name of the view to retrieve the data from.
* @param string $display_id
*      The display id. On the edit page for the view in question, you'll find
*      a list of displays at the left side of the control area. "Defaults"
*      will be at the top of that list. Hover your cursor over the name of the
*      display you want to use. A URL will appear in the status bar of your
*      browser. This is usually at the bottom of the window, in the chrome.
*      Everything after #views-tab- is the display ID, e.g. page_1.
* @param array $args
*      Array of arguments. (no keys, just args)
* @return
*      array
*          An array containing an object for each view item.
*      string
*          If the view is not found a message is returned.
*/
function views_get_view_result($viewname, $display_id = NULL, $args = NULL) {
  $view = views_get_view($viewname);
  if (is_object($view)) {
    if (is_array($args)) {
      $view->set_arguments($args);
    }
    if (is_string($display_id)) {
      $view->set_display($display_id);
    }
    else {
      $view->init_display();
    }
    $view->pre_execute();
    $view->execute();
/*  print "<pre> $viewname: $display_id";
    print_r(get_class_methods($view));  */
    return $view->result;
  }
  else {
    return t('View %viewname not found.', array('%viewname' => $viewname));
  }
}

解决方案

As for passing data ranges and given the posted function definition, you could pass date ranges to that only if the view would accept them as arguments. I'm not 100% sure, but afaik date ranges can only be defined as filters, not as arguments, which leads to your second Question:

Programmatically altering the views filter settings is possible, but a bit messy, given the rather complicated view object/array mashup structure. In your posted function above, the first line is

$view = views_get_view($viewname);

After that, $view contains the whole view object. The filter settings are defined per display, so assuming you have a view with only a default display, you will find the filter settings under

$view->display['default']->display_options['filters']

(Note the object/array notation mix - the display is a contained object of type views_display)

The 'filters' array contains one entry per filter, with varying elements depending on the filter type. For your purpose, I would suggest to create a dummy view with just the filter you are interested in, with preconfigured/hardcoded values. Using a debugger (or var_dump/print_r) you can then take a look at the filter array after view creation. From what you find there, you should be able to deduce how to inject your custom date range.

Disclaimer: Poking around in the view like this is a bit annoying and not to effective, but it works. As of yet, I have not found a concise documentation of Views2 that would explain the innards in a straight forward way, as I find the official API documentation a bit lacking concerning the usage from code. (Of course this could well be just me being to stupid ;)
