在ZF2中,如何创建多个提交按钮,每个按钮都指向不同的路径?在ZF2教程的Forms and actions chaper中,使用单个提交按钮创建表单,其中标签为“Go”,用于处理输入数据并返回索引页面(路径)。如果我们想要四个按钮,我们在哪里放置相关的脚本:
Save
操作:保存用户输入,路由:返回当前页面Save and Close
操作:保存用户输入,路由:返回索引(相册)Clear
操作:无操作,路线:返回当前页面Close
动作:无动作,路线:返回索引(专辑)我假设按钮是这样创建的:
namespace Album\Form;
class AlbumForm extends Form
{
public function __construct($name = null)
{
// ... //
$this->add(array(
'name' => 'savebutton',
'attributes' => array(
'type' => 'submit',
'value' => 'Save',
'id' => 'savebutton',
),
));
$this->add(array(
'name' => 'save_closebutton',
'attributes' => array(
'type' => 'submit',
'value' => 'Save & Close',
'id' => 'save_closebutton',
),
));
$this->add(array(
'name' => 'clearbutton',
'attributes' => array(
'type' => 'submit',
'value' => 'Clear',
'id' => 'clearbutton',
),
));
$this->add(array(
'name' => 'closebutton',
'attributes' => array(
'type' => 'submit',
'value' => 'Close',
'id' => 'closebutton',
),
));
}
}
只有一个提交按钮,这就是编辑操作的样子:
// module/Album/src/Album/Controller/AlbumController.php:
//...
// Add content to this method:
public function editAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
if (!$id) {
return $this->redirect()->toRoute('album', array(
'action' => 'add'
));
}
$album = $this->getAlbumTable()->getAlbum($id);
$form = new AlbumForm();
$form->bind($album);
$form->get('submit')->setAttribute('value', 'Edit');
$request = $this->getRequest();
if ($request->isPost()) {
$form->setInputFilter($album->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$this->getAlbumTable()->saveAlbum($form->getData());
// Redirect to list of albums
return $this->redirect()->toRoute('album');
}
}
return array(
'id' => $id,
'form' => $form,
);
}
//...
由于成对的按钮具有相同的表单动作,而成对的按钮具有相同的路径,我想在这里添加两个if语句,除非switch语句更好。

快速肮脏的方式来做你需要的事情:
public function editAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
if (!$id) {
return $this->redirect()->toRoute('album', array(
'action' => 'add'
));
}
$album = $this->getAlbumTable()->getAlbum($id);
$form = new AlbumForm();
$form->bind($album);
$form->get('submit')->setAttribute('value', 'Edit');
$request = $this->getRequest();
if ($request->isPost()) {
$form->setInputFilter($album->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$input = $form->getData();
if (!empty($input['save_closebutton'])) {
return $this->redirect()->toRoute('album', array(
'controller' => 'AlbumController',
'action' => 'index',
));
}
}
}
return array(
'id' => $id,
'form' => $form,
);
}
