如何在Drupal 7中创建自定义块?

I want to create a custom block in which I want to show custom form.

Form will contain only two element.

  • input box (#centimeter)
  • submit button

When this submit button is clicked I want to convert this centimeter in inch and display the result below this form and I want to show this in block in sidebar.

My questions:

  1. How to do this?
  2. I tried following link but don't know where to write the code - should I create any php file in some folder?
  3. What to do if I want to show this block as a page with some url like /measurement/convert-cm-to-inches

我想创建一个自定义块,我想在其中显示自定义表单。

表单只包含两个元素。

  • 输入框( #centimeter
  • 提交按钮

    单击此提交按钮时,我想以英寸为单位转换此厘米并在此表单下方显示结果,我想在侧栏中的块中显示此内容。

    我的问题:

    1. 如何做到这一点?
    2. 我试过以下链接但不知道在哪里写代码 - 我应该 在某个文件夹中创建任何php文件?
    3. 如果我想将此块显示为带有一些URL的页面,如 / measurement / convert-cm-to-inches

    <?php
    /**
     * Implements hook_block_view().
     */
    function your_module_block_view($block_name = '')
    {
        // in my example I show the form only in the front page.
        // You can show it where you want, obviously
        if (!drupal_is_front_page())
        {
            return NULL;
        }
    
        $form = drupal_get_form('your_module_form');
        $block = array
        (
            // 'subject' => t('Subject'),
            'content' => $form,
        );
    
        return $block;
    }
    
    /**
     * Implements hook_form().
     */
    function your_module_form($form, &$form_state)
    {
        // now I add a text field to the form
        // with a label and fixed dimensions (you never know...)
        $form['text'] = array
        (
          '#title' => t('Label for the text box'),
          '#type' => 'textfield',
          '#size' => 32,
          '#maxlength' => 128,
        );
    
        // now I add also a button
        $form['submit'] = array
        (
           '#type' => 'submit',
           '#value' => t('Submit'),
        );
    
        // and now I assign a my function as handler of the submit event 
        $form['#submit'][] = 'your_module_submit_handler';
        return $form;
    }
    
    function your_module_submit_handler($form, &$form_state)
    {
        // this function will be executed after the click
        // event of the user on the "submit" button.
        // here I only print a message
        // you can access a database, redirect, or whatever you want, obviously 
        drupal_set_message(t('Ok!'));
    }
    ?>
