Codeigniter在视图中使用foreach [英] Codeigniter using foreach in view

问题描述

我在Apache xampp上使用Codeigniter，并尝试在视图中首次使用foreach，但我无法使其正常工作。

I'm using Codeigniter on an Apache xampp set up and attempting to use foreach in a view for the first time and I just can't get it to work.

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');
    }
}

我的模型：

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'];
        }
    }
}

我的视图：

<main id='central_section'>
    <section id='logo_section'>
    <img src='<?php echo base_url(); ?>img/logo.png' id='small_logo' alt="Logo">
    </section>
    <section id='content'>
        <p class="large_headding">News</p>

            <?php foreach($news as $news) { ?>
                <article class="article_text">
                    <p class="segment_headding"><?php echo $news->date; ?></p>
                        <?php echo $news->text; ?>
                </article>
            <?php } ?>
        <div id="spacer"></div>
    </section>
</main>

目前，我收到以下警告消息：

At present I get the following warning message:

A PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

Filename: views/testv.php

Line Number: 18

Backtrace:

File: C:\xampp\htdocs\tsh\CI\application\views\testv.php
Line: 18
Function: _error_handler

File: C:\xampp\htdocs\tsh\CI\application\controllers\test.php
Line: 16
Function: view

File: C:\xampp\htdocs\tsh\public_html\index.php
Line: 292
Function: require_once

但是数据库中的文本确实出现在页眉顶部之外的页面顶部，因此我知道数据库正在连接并且正在收集数据库中的数据。谁能告诉我我要去哪里错了？

But the text from my database does appear at the top of the page outside of the headder so I know the database is connecting and the data from it is being collected. Can anyone tell me where I'm going wrong?

推荐答案

您在模型函数中遇到问题foreach循环只需将其替换为：

you just have issue in your model function foreach loop just replace that with:

$query = $this->db->query('SELECT id, date, text FROM news');
$result = $query->result_array();
return $result;
