Question

我在Drupal中处理事物的一种常见方法是创建一个CCK类型，然后创建一个自定义提交处理程序，以便在提交节点时在CCK字段上执行逻辑。但是，当CCK字段类型是Date字段时，我无法获取该值，因为该数组的结构不同。

更新 - JoãoGuilherme有一个更简单的方法，但我仍然无法从下面发布的数组中获取日期值。

$fromDate = $form['field_bill_start'][0]['#value'];
drupal_set_message('<pre>'. print_r($fromDate, TRUE) .'</pre>');

//Which then prints this.
Array
(
    [value] => Array
        (
            [date] => Tue, 08/24/2010
        )

)

然后我尝试添加打印null的这些。我还在日期和价值之前尝试了“＃”。

['value']['date']

*************************原帖******************** **************

<?php
 function billing_form_billing_node_form_alter(&$form, &$form_state) {
  //drupal_set_message('We are hooking it!');
  $form['#submit'][] = 'billing_submit_function';
}

function billing_submit_function($form, &$form_state) {
  $fromDatePRE = array();
  $fromDatePRE[] =  $form['field_bill_start'][0]['value']['date'];
  $fromDate[] = $fromDatePRE[0]['#value']['#date'];

  drupal_set_message('<pre>'. print_r($fromDatePRE[0], TRUE) .'</pre>');


  drupal_set_message("From Date = ".$fromDate[0]);
  drupal_set_message("From Date2 = ".$fromDatePRE[0]);

$ fromDate正在打印星期六8/21/2010的第一个字符“S”，这是我想要的值，但我想要整个值。我知道这与我如何访问阵列有关，但我无法弄明白。

这就是我正在使用的内容 - 我对我正在尝试访问的值添加了评论：

Answer 1

您应该使用$form_state;

上用户提交的值

我使用单个日期字段进行测试，而不是具有2个值的日期字段。但无论如何这应该工作得很好。我的字段命名可能不正确，但您可以查看$form_state['values']上的值，您应该在哪里找到您的字段。

无论如何，代码看起来像这样：

function billing_submit_function($form, &$form_state) {
  $from_date =  $form_state['values']['field_bill_start'][0]['value'];
  $from_date_string = format_date(strtotime($from_date), 'custom', 'D d/m/Y');
  $from_date_2 =  $form_state['values']['field_bill_start'][0]['value2'];
  $from_date_string_2 = format_date(strtotime($from_date_2), 'custom', 'D d/m/Y');

  drupal_set_message("From Date = ".$from_date_string);
  drupal_set_message("From Date2 = ".$from_date_string_2);
}

Answer 2

您获得的回报是因为您正在访问字符串，而不是数组。

$string = "ABCDEFG";
// This would print "A".
print $string[0];

要注意，提交处理程序会从$form_state['values']获取提交的值，而不是$form。

Answer 3

尝试这个，我删除了我之前的答案，一旦我真的看了代码，发现我之前已经离开了。似乎有很多冗余阵列在我看来只是混淆了这个问题。这有用吗？

$fromDate = $form[0]['#post']['field_bill_start'][0]['value']['date'];
drupal_set_message("From Date = ".$fromDate);

编辑：

更新了代码以再试一次

Answer 4

我认为您只需要打印$form['field_bill_start'][0]['#value']。

更新：直接打印$form['field_bill_start'][0]['#value']，不要将其添加到变量或数组中。

访问post变量时只获取第一个字符
