form_validation CodeIgniter

Question

我想知道我做错了什么，所以无论我在表单中输入什么电子邮件地址，它都会返回＆＃34;无法访问与您的字段名称电子邮件地址相对应的错误消息。（电子邮件）＆＃34;并且表格无法成功发送。

<?php echo validation_errors('<p class="error">'); ?>

    <?php echo form_open('home/send'); ?>

        <table>
            <tr>
                <th>
                    <label for="name">Name</label>
                </th>
                <td>
                    <input type="text" name="name" id="name" value="<?php echo set_value('name'); ?>">
                </td>
            </tr>
            <tr>
                <th>
                    <label for="email">Email</label>
                </th>
                <td>
                    <input type="text" name="email" id="email" value="<?php echo set_value('email'); ?>">
                </td>
            </tr>
            <tr>
                <th>
                    <label for="message">Message</label>
                </th>
                <td>
                    <textarea name="message" id="message"><?php echo set_value('message'); ?></textarea>
                </td>
            </tr>
        </table>
        <?php echo form_submit('submit', 'Submit'); ?>

    <?php echo form_close(); ?>



function send()
{
    $this->load->library('form_validation');

    $this->form_validation->set_rules('name', 'Name', 'trim|required');
    $this->form_validation->set_rules('email', 'Email Address', 'trim|required|email');
    $this->form_validation->set_rules('message', 'Message', 'trim|required');


    if($this->form_validation->run() == false) {

        $data['page_title'] = "Contact Mike";
        $data['section'] = "contact";

        $this->load->view('templates/header', $data);
        $this->load->view('contact', $data);
        $this->load->view('templates/footer', $data);

    } else {}

Answer 1

使用视图文件中的form_error()函数

<?php echo form_error('username'); ?>
    <input type="text" name="username" value="<?php echo set_value('username'); ?>" size="50" />

Answer 2

规则应该是 valid_email ，根据文档：

$this->form_validation->set_rules('email', 'Email Address', 'trim|required|valid_email'); 

您已放置不存在的电子邮件＆＃39;在那里统治...
