本文介绍了在Drupal中创建一个非常简单的表单的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我需要做的只是一个表单:

All I need to do is have a form that does this:


  1. 用户在文本框中输入邮政编码

  2. 提交用户被重定向到mysite.com/[user postcode]

就是这样!我知道验证等也是可取的,但是我现在只需要做这个工作。我不介意如果它是编码或利用Drupal表单API(实际上我更喜欢前者!)。

That's it! I know validation etc. would be desirable as well, but I just need to get this working for now. I don't mind if it's harcoded or utilises the Drupal form API (actually I'd prefer the former!).

我知道这是死的简单,但不幸的是我来自前端的背景,并有一点了解这种事情:(

I know this is dead simple, but unfortunately I'm coming from a front-end background and have a bit to learn about this sort of thing :(

干杯!

推荐答案

表单API 很简单和自定义模块,您将使用Form API构建一个表单,并添加一个更改的提交处理程序最后,您需要创建一种访问表单的方法(通过创建菜单项或创建块)。

This is pretty easy with the Form API and a custom module. You'll build a form using the Form API and add a submit handler that changes the redirect for the form to whatever you'd like. Finally, you'll need to create a way to access the form (either by creating a menu item or by creating a block).

这是一个实现一个您想要的窗体的示例:您将要阅读Form API参考,以查看构建表单时所需的所有选项,还提供了两种访问方式形式:

Here's an example that implements a form like you want: you'll want to peruse the Form API reference to see all the options you have when building a form. It also provides two ways to access the form:


  1. 使用 http://example.com/test

  2. 使用 hook_block() 提供一个包含可以在块管理页面上添加和移动的表单的块。

  1. Using hook_menu() to provide a page for the form at http://example.com/test
  2. Using hook_block() to provide a block containing the form that you can add and move around on the block administration page.

示例代码:

// Form builder. Form ID = function name
function test_form($form_state) {

  $form['postcode'] = array(
    '#type' => 'textfield',
    '#title' => t('Postcode'),
    '#size' => 10,
    '#required' => TRUE,
  );
  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Go'),
  );

  return $form;
}

// Form submit handler. Default handler is formid_submit()
function test_form_submit($form, &$form_state) {
  // Redirect the user to http://example.com/test/<Postcode> upon submit
  $form_state['redirect'] = 'test/' . check_plain($form_state['values']['postcode']);
}

// Implementation of hook_menu(): used to create a page for the form
function test_menu() {

  // Create a menu item for http://example.com/test that displays the form
  $items['test'] = array(
    'title' => 'Postcode form',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('test_form'),
    'access arguments' => array('access content'),
    'type' => MENU_NORMAL_ITEM,
  );

  return $items;
}

// Implementation of hook_block(): used to create a movable block for the form
function test_block($op = 'list', $delta = 0, $edit = array()) {
  switch ($op) {
    case 'list': // Show block info on Site Building -> Blocks
      $block['postcode']['info'] = t('Postcode form');
      break;
    case 'view':
      switch ($delta) {
        case 'postcode':
          $block['subject'] = t('Postcode');
          $block['content'] = drupal_get_form('test_form');
          break;
      }
      break;
  }

  return $block;
}
