CakePHP：如何使用表单助手同时更新多条记录

php
echo $this->Form->create();
foreach ($users as $user) {
    echo $this->Form->select('User.' . $user['id'] . '.role', $roles);
}
echo $this->Form->button('Save');
echo $this->Form->end();

php
public function updateRoles()
{
    if ($this->request->is('post')) {
        $data = $this->request->getData();
        $users = [];
        foreach ($data['User'] as $id => $userData) {
            $user = $this->Users->get($id);
            $user = $this->Users->patchEntity($user, $userData);
            $users[] = $user;
        }
        if ($this->Users->saveMany($users)) {
            $this->Flash->success(__('Roles updated successfully.'));
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error(__('Failed to update roles.'));
        }
    }
}

php
// 在控制器中
public function edit()
{
    if ($this->request->is('post')) {
        $data = $this->request->getData();
        $users = [];
        foreach ($data['User'] as $id => $userData) {
            $user = $this->Users->get($id);
            $user = $this->Users->patchEntity($user, $userData);
            $users[] = $user;
        }
        if ($this->Users->saveMany($users)) {
            $this->Flash->success(__('Records updated successfully.'));
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error(__('Failed to update records.'));
        }
    }
}
// 在视图中
echo $this->Form->create();
foreach ($users as $user) {
    echo $this->Form->text('User.' . $user['id'] . '.name');
    echo $this->Form->text('User.' . $user['id'] . '.email');
}
echo $this->Form->button('Save');
echo $this->Form->end();
