我花了很多时间试图解决这个问题并且运气为零。我试过路由没有成功。我会把逻辑放在第一位，然后是代码。

  1. 用户在 /pra/Fields/view/1 中查看 fields.template_id=1 的字段列表
  2. 用户单击添加新字段/pra/Fields/add_new/1，他们将进入一个表单，在该表单中输入他们想要的关于他们创建的新字段的信息。
  3. 当用户单击添加/提交时，新字段将保存到数据库中
  4. 用户被带回 /pra/Fields/view/1，因此他们可以看到添加到模板中的新字段

目前前 3 个步骤正在发生，但是当涉及到重定向回/pra/Fields/view/1用户被重定向到/pra/Fields/view/

这是 add_new 函数的代码

function add_new($id=null){
    //allows users to add another field to an existing template
    $this->set('title_for_layout', 'Create Fields');
    $this->set('stylesheet_used', 'homestyle');
    $this->set('image_used', 'eBOXLogoHome.png');
    $this->layout='home_layout';
    $name=$this->Field->field('template_id', array('template_id'=>$id));
    //if the field data saves
    $this->set('name',$name);
    if(($this->Field->save($this->data)))
    {   
        //user is redirected to fields/view/$name
        $this->redirect(array('controller'=>'Fields', 'action'=>'view',$name));
    }
    //sets the $id variable
    $this->set('id',$id);

这是 add_new 视图

<table id="formatform">
        </br></br>
        <?php
            $options = array('Money'=>'Money','Text'=>'Text','Description'=>'Description');
            ?>
        <?php echo $this->Form->create('Field', array('action'=>'add_new')); ?>
        <?php echo $this->Form->input('id',array('type'=>'hidden')); ?>
                <tr>
                <td></td>
                <td><?php echo $this->Form->input('template_id',array('type'=>'hidden','default' => $id)); ?></td>
                </tr>

                <tr>
                <td align='center'>Field Name:</td>
                <td align='left'><?php echo $this->Form->input('name', array('label'=>false)); ?></td>
                </tr>

                <tr>
                <td align='center'>Default Value:</td>
                <td align='left'><?php echo $this->Form->input('default_value', array('label'=>false)); ?></td>
                </tr>
                <tr>
                <td align='center'>Field Type:</td>
                <td align='left'><?php echo $this->Form->input('field_type', array('label'=>false,'type'=>'select','options'=>$options)); ?></td>
                </tr>

                <tr>
                <td align='center'>Description:</td>
                <td align='left'><?php echo $this->Form->input('description', array('label'=>false)); ?></td>
                <td><?php echo $this->Form->input('active', array('type'=>'hidden','default'=>true)); ?></td>
                </tr>




    <td></td>   <td align = "left"><?php echo $this->Form->end('Submit');?></td>

这是查看功能代码

function view($name){
    //lists information about fields that correspond to the
    //template they have clicked 'view' on
    $this->set('title_for_layout', 'Field Details');
    $this->set('stylesheet_used', 'homestyle');
    $this->set('image_used', 'eBOXLogoHome.png');
    $this->layout='home_layout';
    //sets $conditions where template_id=$name and field.active=true
    $conditions=array(
        "AND"=>array(
        'template_id'=> $name,
        'Field.active'=>true));
    //finds all fields where 'conditions'=$conditions
    $fields = $this->Template->Field->find('all',array( 
        'conditions' => $conditions));
    //sets all the variables      
    $this->set('conditions', $conditions);
    $this->set('field', $fields);
    $this->set('field', $this->paginate('Field', $conditions));

您可能会在这里遇到问题：

function add_new($id=null){
    //allows users to add another field to an existing template
    $this->set('title_for_layout', 'Create Fields');
    $this->set('stylesheet_used', 'homestyle');
    $this->set('image_used', 'eBOXLogoHome.png');
    $this->layout='home_layout';

检查 $name 是否不为空

$name = $this->Field->field('template_id', array('template_id'=>$id)); 
if(!empty($name)){
    $this->set('name',$name);
    if(($this->Field->save($this->data)))
    {   
        //user is redirected to fields/view/$name
        $this->redirect(array('controller'=>'Fields', 'action'=>'view',$name));
    }
}

你的其余代码

//sets the $id variable
$this->set('id',$id);
