Zend Framework 1 - 提交按钮不起作用（点击后没有帖子）

Question

此表单中的所有功能都有效 - 获取最大和贷方余额，会话功能等。但是，单击时，提交按钮不执行任何操作。它应该由控制器处理该表单所在的页面，但它没有那么远。没有请求帖子。如果有人能帮助我，我会非常感激。

<?php class Application_Form_Redeem extends Zend_Form
{
protected $identity;

public function init()
{

    //make sure it doesn't accept a number greater than available balance
    $this->identity = Zend_Auth::getInstance()->getIdentity();
    $username=$this->identity->username;    

    $users = new Application_Model_DbTable_User();
    $creditBal=$users->getCreditBal($username);

    //make sure it doesn't accept a number greater than maxRedemption
    $sess = new Zend_Session_Namespace('BusinessID');
    $retailerID = $sess->id;

    //echo "RETAILERID: " . $retailerID;

    $partners = new Application_Model_DbTable_Partners();
    $maxRedemption= $partners->getMaxRedemption($retailerID);       

    // Create a validator chain and add validators to it
    $validatorChain = new Zend_Validate();

    $validatorChain
        ->addValidator(new Zend_Validate_GreaterThan(array('min' => 0,)))
