Question

我尝试从控制器回显一条消息来查看，它甚至都没有显示它。

验证用户输入的所有电子邮件，发送有效的电子邮件并显示无效的电子邮件。

但是当按下提交时，它不会显示那些在视图中无效的内容，但它会发送有效的内容。

这是我的一些代码：

<form method="post" action="<?php echo $this->url(array(), 'inviteByEmail'); ?>">
            <table><tr>
                <td>Email Addresses:* <span class="right small_font" style="margin-right:25px;">* Each email address must be separated by a comma ( , )</span></td>
                <td></td>
            </tr><tr>
                <td><input class="input_long" type="text" name="emails" /></td>
            </tr><tr>
                <td><br/>Personalize your message:</td>
            </tr><tr>
                <td><textarea cols="49" rows="7" name="personal_message"  id="share-text" style="margin-bottom:8px;" placeholder="Download Ad-Aware and help me get PRO version" ></textarea></td>
            </tr><tr>
                <td rowspan="3" valign="top">
                    <input type="submit" class="btn_submit_step3" id="btn_friends" value="share_friends" /><br/>
                </td>
            </tr></table>
        </form> <?php echo $this->error; ?>

控制器：

public function inviteByEmailAction()
{
    $emails = $this->getRequest()->getParam('emails');
    $personal_message = $this->getRequest()->getParam('personal_message');

    $emails = explode(",", $emails);

    foreach ($emails as $email)
    {
        $email = trim($email);
        $validator = new Zend_Validate_EmailAddress();

        // Validate emails that exists in Database
        $valiadtor_email_in_dbUsers = new Zend_Validate_Db_NoRecordExists (
            array (
                'table' => 'users',
                'field' => 'email'
            )
        );

        $valiadtor_email_in_dbReferrals = new Zend_Validate_Db_NoRecordExists (
            array (
                'table' => 'referrals',
                'field' => 'email'
            )
        );

        if ($validator->isValid($email)) 
        {
            if ($valiadtor_email_in_dbUsers->isValid($email))
            {
                if ($valiadtor_email_in_dbReferrals->isValid($email))
                {
                    if ($this->_helper->model('EmailInvites')->noRowByFields(array('email' => $email, 'referred_by_user_id' => $this->_helper->user()->id)))
                    {
                        $email_invite = $this->_helper->model('EmailInvites')->createRow();  
                        $email_invite->email = $email;
                        $email_invite->personal_message = $personal_message;
                        $email_invite->referred_by_user_id = $this->_helper->user()->id;
                        $email_invite->save();

                        $this->_helper->user()->sendInviteEmail($email, $personal_message);
                    }
                } else {
                    echo $email . " already exists";
                                            $this->view->error = $email . " already exists";
                }
            }else {
                    echo $email . " already exists";
                                            $this->view->error = $email . " already exists";
                }
        }
    }
    $this->getHelper('redirector')->gotoRoute(array(), 'invite');
}

echo在inviteByEmailAction（）中。这意味着，它将显示在inviteByEmail.phtml视图中。但是，在回显之后，您将在此行重定向到inviteAction。

  $this->getHelper('redirector')->gotoRoute(array(), 'invite');

这就是为什么你看不到显示的回声。

如果您不希望在出现错误时发生重定向，则需要在echo之后添加一个return语句：

   } else {
                echo $email . " already exists";
                $this->view->error = $email . " already exists";
                 return;
            }
        }else {
                echo $email . " already exists";
                $this->view->error = $email . " already exists";
                return;
            }

如果要重定向并显示错误消息，可以在重定向之前使用Flashmessenger帮助程序。
