CakeWizard组件-在下一步中从上一步回显会话数据

我对Cakephp很陌生，在过去的两个月里我一直在开发一个项目，使用向导组件来帮助创建多页表单。

我的问题是如何将会话数据从上一步设置为流程中下一步的视图。

到目前为止，我在控制器中设置了

控制器/Uploadstylecontroller.php

CakePlugin::load('Wizard');
class UploadstyleController extends AppController {
    var $uses = array('Post');
        public $components = array('Wizard.Wizard');
        var $username = array();
    public function beforeFilter(){
        $this->layout = 'loggedinnorightbar';
        $this->Auth->allow('wizard','uploadstyle','styledetails','uploadcomplete');
        $this->Wizard->steps = array( 'uploadstyle','editpicture');
        $this->Wizard->wizardAction = '/uploadstyle/wizard/uploadstyle';
        $this->Wizard->completeUrl = '/uploadstyle/uploadcomplete';
        }
        public function uploadcomplete(){
        }
        public function wizard($step = null) {
        $this->Wizard->process($step);
    }
/**
 * [Wizard Process Callbacks]
 */
    public function processUploadstyle() {
        $this->Post->set($this->data);
        if($this->Post->validates()) {
            return true;
        }
        return false;
    }
    public function processEditpicture() {
        $uploadstyle = $this->Wizard->read();
        $this->set( 'uploadstyle',$uploadstyle );
        if($this->Post->validates()) {
            return true;
        }
        return false;
    }

我不会为保存数据而烦恼，因为它工作得很好。

和uploadstyle/editpicture.ctp

<div class="signupwrapper" style="position:relative; width:470px; margin-top:30px;">
<?php echo $this->Form->create('Uploadstyle', array('id' => 'UploadstyleForm', 'url' => '/uploadstyle/wizard/editpicture'));

    echo $this->Form->hidden('Post.shines', array('value' =>  0));
    echo $uploadstyle['Post']['image_name'];
    ?>
    <div class="submit">
        <?php echo $this->Form->submit('Continue', array('div' => false)); ?>
        <?php echo $this->Form->submit('Cancel', array('name' => 'Cancel', 'div' => false)); ?>
    </div>
<?php echo $this->Form->end(); ?>
</div>

关于'echo $upload['Post']['image_name']'在组件中是否有我需要激活的东西，或者我在视图中错误地引用数组?

任何帮助都将非常感激!

如果这是一个很长的问题，我很抱歉，这是我第一次在这里问问题。
