无法从form_input中获取文本

Question

我正在尝试获取视图输入框中的项目。     我正在使用：

$email = $this->input->post('email', true);

为了获得输入框内的内容。但它没有获得任何东西。

该功能运行于：

<?php $function = array('auth/start', $price);?>

<form action="<?php echo base_url($function);?>"method="post">
<script
src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="pk_test_xZrfWwuBmwBzUBynB96OgZhU"
data-amount="" 
data-name="Turbine Engine"
data-description="Individual Membership"
data-image="/128x128.png">
</script>
</form>

我有以下内容：

控制器：

function start()
           {
                $username = 'a';
                $price = '100';
                $password = 'password';
                $email = $this->input->post('email');

                $end = date('Y-m-d', strtotime('+1 years'));

                $additional_data = array(
            'first_name' => $this->input->post('first_name'),
                            'middle_initial' => $this->input->post('middle_initial'),
            'last_name'  => $this->input->post('last_name'),
            'company'    => $this->input->post('company'),
            'phone'      => $this->input->post('phone'),
                        'biography'      => $this->input->post('biography'),
                        'address'      => $this->input->post('address'),
                        'city'      => $this->input->post('city'),
                        'state'      => $this->input->post('state'),
                        'zip'      => $this->input->post('zip'),
                        'position'      => $this->input->post('position'),
                        'country'      => $this->input->post('country'),
                        'website'      => $this->input->post('website'),
                            'listing'               => 'N',
                            'type'                  => 'I',
                            'registration_end' => $end,
        );


               //load payment library
               $this->load->library( 'stripe' );


               // Get the credit card details submitted by the form
               $token = $_POST['stripeToken'];



               // Create the charge on Stripe's servers - this will charge the user's card
                try {


                    //attempt to charge user
                    $this->stripe->charge_card( intval($price), $token, "Individual Membership" );
                    } 
                    catch(Stripe_CardError $e) 
                    {
                      // The card has been declined
                    }


        //If passed then add a new user
                    //add the user
                    $this->ion_auth->register($username, $password, $email, $additional_data);
        $this->session->set_flashdata('message', 'Payment Successful');

                  //TEST
                  //load parameters
                  $type = 'new account';
                  $date = date('Y-m-d');
                  date_default_timezone_set('Australia/Melbourne');
                  $time = date('h:i:s a', time());
                  //load the controller for adding activity
                  $this->load->library('../controllers/activity');
                  $this->activity->insert($email, $type, $date, $time);

                    //send to login
                    //$this->showView('login');
        redirect("auth", 'refresh');

     }

谢谢。我感谢任何帮助。

Answer 1

在您看来，你有这个：

//...
<?php echo form_input(array('id' => 'email', name'=>'email','value'=>$email,'size'=>'30', 'readonly'=>'true'));?>
//...
<form action="<?php echo base_url($function);?>"method="post">
    // ...
</form>

但是您在此输入之前没有打开表单，因此您的输入未提交，因此请首先打开表单：

echo form_open('url here');
    echo form_input(array('id' => 'email', 'name'=>'email','value'=>$email,'size'=>'30', 'readonly'=>'true'));
    //other inputs...
form_close();

form_open打开/创建开始表单标记，form_close创建结束表单标记。您还可以使用<form>和</form>，然后将所有输入放在表单中：

<script src="https://checkout.stripe.com/checkout.js" class="stripe-button" ...></script>

详细了解Form Helper。

Answer 2

输入表单中没有任何form_open（）和form_close（）。请更新您的代码，这将解决您的问题。

Answer 3

要发布文字字段，您需要将其括在表单标记

中

<input type="text" name="email" value="" />
<form action="someurl" method="post">
</form>

在这种情况下，什么都不会发布到服务器 如果您需要发布文本字段，则需要在表单标记内移动

<form action="someurl" method="post">
    <input type="text" name="email" value="" />
</form>

或

form_open('someurl');
   <?php echo form_label("Email:");?> <br />
   <?php echo form_input(array('id' => 'email', name'=>'email','value'=>$email,'size'=>'30', 'readonly'=>'true'));?>
form_close();

确保所有文本字段都包含在表单

中
