访问 post 变量时仅获取第一个字符
我在 Drupal 中处理事务的常用方法是创建 CCK 类型，然后创建自定义提交处理程序以在提交节点时对 CCK 字段执行逻辑。但是，当 CCK 字段类型为日期字段时，我无法获取该值，因为数组的结构不同。
更新 - João Guilherme 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
)
)
然后我尝试添加这些打印 null 的内容。我还尝试了日期和值之前的“#”。
['value']['date']

<?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 Sat 8/21/2010 的第一个字符“S”，这是我想要的值 ，但我想要整个值。我知道这与我访问数组的方式有关，但我无法弄清楚。
这就是我正在处理的内容 - 我向我尝试访问的值添加了注释：

A common way I handle things in Drupal is to create a CCK type, and then create a custom submit handler to perform logic on the CCK fields when the node is submitted. However, I have been unable to get the value when the CCK field type is a Date field because the array is structured differently.
UPDATE - João Guilherme had a much simpler approach, but I still couldn't get the date value out of the array posted below.
$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
)
)
I then tried adding these which printed null. I also tried the "#" before date and value.
['value']['date']

$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 is printing the first character "S" of Sat 8/21/2010 which is the value I want , but I want the whole value. I know this has something do with how I'm accessing the array but I can't figure it out.
This is what I'm working with - I added a comment to the value I'm trying to access:

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，您应该在其中找到列出的字段。无论如何，代码看起来像这样：
You should use the value submitted by the user which is on the
$form_state;I tested with a single date field, instead of a datefield with 2 values. But this should work just fine anyways. I might have the naming of your field incorrect, but you can check out the values on
$form_state['values'], where you should find your field listed.Anyways the code would look something like this:
您得到的返回是因为您正在访问字符串，而不是数组。
请注意，提交处理程序从
$form_state['values']获取提交的值，而不是从$form获取。The return you get is because you are accessing a string, and not an array.
To notice then that a submission handler takes the submitted values from
$form_state['values'], not from$form.试试这个，当我真正查看代码并发现我之前已经偏离了方向时，我删除了之前的答案。似乎创建了很多冗余数组，在我看来，这些数组只是让问题变得混乱。这有效吗？
编辑：
更新代码以再试一次
Try this instead, I deleted my previous answer once I really looked at the code and noticed I was way off before. There seems to be a lot of redundant arrays created that in my opinion are just confusing the issue. Does this work?
EDIT:
Updated the code to have another try
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。I think you just need to print
$form['field_bill_start'][0]['#value'].Update: print directly the
$form['field_bill_start'][0]['#value'], don't add it to a variable or array.
