小编Tes*_*ssa的帖子

我在 Apache xampp 设置上使用 Codeigniter 并首次尝试在视图中使用 foreach，但我无法让它工作。

我的控制器代码：

class Test extends CI_Controller {

        public function index($page = 'testv')
    {
            if ( ! file_exists(APPPATH.'/views/'.$page.'.php'))
            {
                show_404();
            }
                $this->load->model('testm');
                $data['news'] = $this->testm->get_news();

                $this->load->view('headder');
                $this->load->view($page, $data);
                $this->load->view('footer');
    }
}

我的型号：

class Testm extends CI_Model {

    public function __construct()
    {
        parent::__construct();
    }

    Public function get_news()
    {
        $query = $this->db->query('SELECT id, date, text FROM news');

        foreach ($query->result_array() as $row)
        {
            echo $row['id'];
            echo $row['date'];
            echo $row['text'];
        }
    }
}

我的看法：

<main id='central_section'>
    <section id='logo_section'>
    <img …

我正在尝试创建一个表单验证回调函数,但我遇到了一些麻烦.

我想要做的是创建一个联系表单,其中加入邮件列表选项.如果选中加入邮件列表的选项,我希望将该人员的姓名和电子邮件添加到邮件列表数据库中.这部分工作正常,但我也希望功能检查数据库,以确保添加的电子邮件地址是唯一的,这是我无法理解的一点.

控制器:

public function contact()
{
    $this->load->helper('form');
    $this->load->library('form_validation');

    $this->form_validation->set_rules('name', 'your name', 'required', array('required'=>"<p class='required'>Please provide %s</p><br>"));
    $this->form_validation->set_rules('email', 'your email address', 'required', array('required'=>"<p class='required'>Please provide %s</p><br>"));

    if($this->form_validation->run() == FALSE)
    {
        $this->load->view('templates/headder');
        $this->load->view('contact');
        $this->load->view('templates/footer');
    }
    else
    {
        $this->load->library('email');

        $name = $this->input->post('name');
        $email = $this->input->post('email');
        $phone = $this->input->post('phone');
        $message = $this->input->post('message');
        $list = $this->input->post('mailing_list');

        $email_message = "Name: $name<br>Email: $email<br>Phone: $phone<br>Message:<br>$message";

        $this->email->initialize();
        $this->email->from($email, $name);
        $this->email->to('myaddress@mydomain.co.uk');
        $this->email->subject('New Query');
        $this->email->message($email_message);
        $this->email->send();

        if($this->email->send()){
        $this->load->view('send_error');
        }
        else
        {
            if($list == 'no')
            {
            $this->load->view('sent');
            }
            else
            {
                $this->form_validation->set_rules('email', …
