我可以把表单输入关联数组在PHP中进行处理？ [英] Can I put associative arrays in form inputs to be processed in PHP?

问题描述

我知道我可以做这样的事情＆LT;输入名称=富[]＆GT; ，但有可能做的事情，比如 ＆LT;输入名称=福[巴]＆GT; ，并让它在PHP中显示为 $ _ POST ['富'] ['酒吧'] ？

I know I can do things like <input name="foo[]">, but is it possible to do things like <input name="foo[bar]"> and have it show up in PHP as $_POST['foo']['bar']?

的我想问的原因是因为我做的表单元素的一个巨大的表（包括＆LT;选择＆GT; 通过多项选择），我想有说我张贴到脚本干净举办我的数据。我想在每列的输入元件具有相同的基本的名字，但不同的行标识符作为数组密钥。这是否有意义？的

The reason I ask is because I'm making a huge table of form elements (including <select> with multiple selections), and I want to have my data organized cleanly for the script that I'm POSTing to. I want the input elements in each column to have the same base name, but a different row identifier as an array key. Does that make sense?

编辑：我正是尝试这样做了，但显然Drupal是什么，我试图做的干扰。我想我刚开始我的语法错误。萤火告诉我，我的名字输入构造完全一样，但我的数据回来为 [富[巴] =＆GT;数据，而不是 [富] =＆GT;阵列（[巴] =＆GT;数据）。

I tried exactly this already, but apparently Drupal is interfering with what I'm trying to do. I thought I was just getting my syntax wrong. Firebug tells me that my input names are constructed exactly like this, but my data comes back as [foo[bar]] => data rather than [foo] => array([bar] => data).

编辑2：看来我的真正的问题是我的假设，即 $ form_state ['值'] 在Drupal也有同样的阵列层级为 $ _ POST 。我从来没有认为Drupal的将是合理和直观。我为浪费你的时间道歉。您可以去您的业务。

EDIT 2: It seems my real problem was my assumption that $form_state['values'] in Drupal would have the same array hierarchy as $_POST. I should never have assumed that Drupal would be that reasonable and intuitive. I apologize for wasting your time. You may go about your business.

推荐答案

您可以在Drupal这样做也很容易。你必须要记住的重要一点是形式'#tree参数设置为TRUE。为了给你一个简单的例子：

You can do this in Drupal too, quite easily. The important thing you have to remember about is setting form '#tree' parameter to TRUE. To give you a quick example:

function MYMODULE_form() {
  $form = array('#tree' => TRUE);
  $form['group_1']['field_1'] = array(
    '#type' => 'textfield',
    '#title' => 'Field 1',
  );
  $form['group_1']['field_2'] = array(
    '#type' => 'textfield',
    '#title' => 'Field 2',
  );
  $form['group_2']['field_3'] = array(
    '#type' => 'textfield',
    '#title' => 'Field 3',
  );
  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => 'Submit',
  );
  return $form;
}

现在，如果您在MYMODULE_form_submit（$形式和放大器; $ form_state）的print_r（）$ form_state ['值']，你会看到这样的事情：

Now, if you print_r() $form_state['values'] in MYMODULE_form_submit($form, &$form_state), you will see something like this:

Array
(
    [group_1] => Array
        (
            [field_1] => abcd
            [field_2] => efgh
        )

    [group_2] => Array
        (
            [field_3] => ijkl
        )

    [op] => Submit
    [submit] => Submit
    [form_build_id] => form-7a870f2ffdd231d9f76f033f4863648d
    [form_id] => test_form
)
