Question

我正在使用链接在下一页的表单中命名我需要的参数。这是链接代码：

    echo $this->Html->link('Email', array('controller' => 'emails', 'action' => 'add', 'contact_email' => $model), array('class' => 'button add'));

这样做的目的是将电子邮件保存到数据库，然后发送电子邮件（两者都有效）。

我想返回他们点击链接时所在的页面，但是在他们经历了两个以上的页面之后不知道如何访问该模型和ID ...

这是add.ctp

<div class="universities form">
<?php echo $this->Form->create('Email');?>
    <fieldset>
        <legend><?php __('Add Email'); ?></legend>
    <?php
        echo $this->Form->input('subject');
        echo $this->Form->input('email_text');
        echo $this->Form->hidden('email', array('value' => $this->params['named']['contact_email']));
        echo $this->Form->hidden('user_from', array('value' => $this->Session->read('User.id')));
        echo $this->Form->hidden('created', array('value' => date("Y-m-d")));
        echo $this->Form->hidden('modified', array('value' => date("Y-m-d")));
                echo $this->Form->hidden('model', array('value' => $this->params['named']['model']));

    ?>
    </fieldset>
<?php echo $this->Form->end(__('Submit', true));?>
</div>

真正的问题 - 重定向的位置？

$this->redirect(array('controller' => $this->data['Email']['model'], 'action' => 'view', $this->data['model']['id']));

实施答案一后，我在重定向时收到了这些错误（电子邮件保存并成功发送，因此只是重定向问题）。

Answer 1

我建议使用以下方法构建完整的返回URI：

$this->params['controller']
$this->params['action'];
$this->params['pass'];

所以它看起来像这样：

$returnUrl = $this->params['controller'] . '/' . $this->params['action'] . '/' . implode('/', $this->params['pass']);
// let's also replace the slashes with, say, underscores
$returnUrl = str_replace('/', '_', $returnUrl);

echo $this->Html->link('Email', array('controller' => 'emails', 'action' => 'add', 'contact_email' => $model, 'returnUrl' => $returnUrl), array('class' => 'button add'));

在add.ctp

中

echo $this->Form->hidden('returnUrl', array('value' => $this->params['named']['returnUrl']));

并在电子邮件的控制器中

$this->redirect('/' . str_replace('_', '/', $this->data['Email']['returnUrl']));

Answer 2

$this->redirect($this->referer(array('action' => 'index')));

如果引用链接不存在，index是您的默认操作。

例如，您的用户在content/view/my-content，他点击emails/add，填写他的详细信息，提交。引用页面是content/view/my-content，因此他（应该）被重定向回那里。

我将此添加到app_controller.php：

public function sendEmail($to,$from,$subject,$body,$headers=array(),$save_to_db=true)
    {
        if($save_to_db == true)
        {
            //do model crap here
            $this->Email->create();

            $data = array(
                'email' => $to,
                'subject' => $subject,
                'email_text' => $body,
                'user_from' => $from,
            // map fields here
            );
            if($this->Email->save($data) == false) 
            {
                $this->log("Email to '$to' from '$from' with subject '$subject' failed to save into the database!");
            }
        } // end save to db

        $email = new EmailComponent();
        //$email->startup($this);

        //reeset email component
        $email->reset();


        /* SMTP Options */
        $email->smtpOptions = array(
            'port'=>'25', 
            'timeout'=>'30',
            'host' => 'smtp.gmail.com',
            'username'=>'###########',
            'password'=>'###########',
        );

        /* Set delivery method */
        //$email->delivery = 'smtp';
        $email->from = $from;
        $email->to = $to;
        $email->subject = $subject;
        $email->replyTo = $from;
        $email->from = '############ <' . $subject . '>';
        $email->sendAs = 'html'; //Send as 'html', 'text' or 'both' (default is 'text')

        $success = $email->send($this->data['Email']['email_text']);
        if($success == false)
        {
            $this->log("Email to '$to' from '$from' with subject '$subject' failed to send!");
        }

        return true;
    } // end sendEmail

然后在我的电子邮件控制器中设置变量后调用该函数。（例如$ to，$ from，$ subject，$ body，$ headers）
