Zend Forms - populate() and setDefaults()
提问by Scott
Let's say I have a form that collects a first name and a last name:
假设我有一个收集名字和姓氏的表单：
$first_name = new Zend_Form_Element_Text('first_name');
$first_name->setLabel("First Name")
->setRequired(true);
$last_name = new Zend_Form_Element_Text('last_name');
$last_name->setLabel("Last Name")
->setRequired(true);
$form = new Zend_Form();
$form->addElement($first_name)
->addElement($last_name)
If I want to use the "populate($data)" or the "setDefaults($data)" method on the form, how does the array need to be organized? What kind of an array do these functions expect? I haven't been able to find this information in the docs.
如果我想在表单上使用“populate($data)”或“setDefaults($data)”方法，需要如何组织数组？这些函数需要什么样的数组？我无法在文档中找到此信息。
Also, I know that I can set the value when creating the element itself, but this is not what I need.
另外，我知道我可以在创建元素本身时设置值，但这不是我需要的。

The form->populate() method takes an array where the keys are the names of the form fields.
form->populate() 方法接受一个数组，其中的键是表单字段的名称。
The Zend_Db_Table_Row object implements a toArray() method which can be used here (as do many other objects). So you can do stuff like:
Zend_Db_Table_Row 对象实现了一个可以在这里使用的 toArray() 方法（就像许多其他对象一样）。所以你可以做这样的事情：
$form = new MyForm;
$table = new MyTable;
$rowset = $table->find($id);
$row = $rowset->current();
$form->populate($row->toArray());

Array keys are the field names, array values are the field values.
数组键是字段名称，数组值是字段值。
$data = array( 'first_name' => 'Mickey', 'last_name' => 'Mouse' );

FYI - in Zend_Form, $form->populate($data)just makes a call to $form->setDefaults($data).
仅供参考 - 在 Zend_Form 中，$form->populate($data)只需调用$form->setDefaults($data).

simple, create an array
简单，创建一个数组
$data = array('nameInput'=> 'your value');
Add your form to your View
将您的表单添加到您的视图
$this->view->form = $form;
then you add data to the form
然后将数据添加到表单中
$form->populate($data);
