我想创建一个自定义块，我想在其中显示自定义表单。
表单将仅包含两个元素。
- 输入框 （
#centimeter） - "提交"按钮
单击此提交按钮时，我想将此厘米转换为英寸并在此表单下方显示结果，并且我想在侧边栏中的块中显示它。
我的问题：
- 怎么做？
- 我尝试了以下链接，但不知道在哪里编写代码 - 我应该在某个文件夹中创建任何 php 文件吗？
- 如果我想将此块显示为带有一些 url 的页面该怎么办

'content' => $form,

return $block;

$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
