减少分页codeigniter/declare的代码行数

Question

我正在构建一个项目，我必须对数据进行多次分页。

在控制器函数中，有 2 个结果。失败和成功，但无论结果如何，页面都将被重定向回调用函数的页面。

假设该页面上有 2 个数据分页，（例如，如果一个页面有目录和 cmets）。

所以在我的控制器中，代码行会非常高，因为我必须在控制器中添加分页行以获得失败和成功的结果。

这是我的分页代码：

$config['base_url'] = ;
    $config['total_rows'] = $num_rows;
    $config['per_page'] = 10;
    $config['num_links'] = $num_rows;
    $config['uri_segment'] = 4;

    $config['full_tag_open'] = '<ul class="pagination">';
    $config['full_tag_close'] = '</ul>';
    $config['first_link'] = '0';
    $config['last_link'] = 'Last';
    $config['first_tag_open'] = '<li class="page-item">';
    $config['first_tag_close'] = '</li>';
    $config['prev_link'] = '&laquo';
    $config['prev_tag_open'] = '<li class="page-item prev">';
    $config['prev_tag_close'] = '</li>';
    $config['next_link'] = '&raquo';
    $config['next_tag_open'] = '<li class="page-item">';
    $config['next_tag_close'] = '</li>';
    $config['last_tag_open'] = '<liclass="page-item">';
    $config['last_tag_close'] = '</li>';
    $config['cur_tag_open'] = '<li class="page-item active"><a href="#">';
    $config['cur_tag_close'] = '</a></li>';
    $config['num_tag_open'] = '<li class="page-item">';
    $config['num_tag_close'] = '</li>';

这让我的代码变得非常凌乱且难以理解，因为它变得很长。

有什么方法可以让我只执行一次，每次执行时都启动分页。

我认为只需要第一部分，我认为第二部分只能声明一次并使其全局化？

编辑：也许我可以在我的控制器中添加一个构造函数并在那里声明它？它会让它全球化吗？ Idk 如果这是正确的解决方案。还是索引函数？

Edit1：这现在是我的配置文件夹中的 pagination.php 文件。我还对此进行了测试，以检查它是否正在工作/影响我的分页链接。

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

    $config['full_tag_open'] = '<ul class="pagination">';
    $config['full_tag_close'] = '</ul>';
    $config['first_link'] = 'First';
    $config['last_link'] = 'Last';
    $config['first_tag_open'] = '<li class="page-item">';
    $config['first_tag_close'] = '</li>';
    $config['prev_link'] = '&laquo';
    $config['prev_tag_open'] = '<li class="page-item prev">';
    $config['prev_tag_close'] = '</li>';
    $config['next_link'] = '&raquo';
    $config['next_tag_open'] = '<li class="page-item">';
    $config['next_tag_close'] = '</li>';
    $config['last_tag_open'] = '<liclass="page-item">';
    $config['last_tag_close'] = '</li>';
    $config['cur_tag_open'] = "<li class='page-item active'><a href='#'>";
    $config['cur_tag_close'] = "</a></li>";
    $config['num_tag_open'] = '<li class="page-item">';
    $config['num_tag_close'] = '</li>';

Answer 1

只需在 config 文件夹中创建一个 pagination.php 文件并将您的配置放入其中。 codeigniter 将自动加载您的配置。

Answer 2

最简单/最短的方法是使用array_fill_keys 和array_merge，例如：

$keys = ['first_tag_close', 'next_tag_close','prev_tag_close',
         'last_tag_close','num_tag_close'];
$config = array_merge($config, array_fill_keys($keys, '</li>'));

不过，简单的重复使用也会缩短行数：

$config['first_tag_open'] = $config['last_tag_open'] =
    $config['next_tag_open'] = '<li class="page-item">';
$config['first_tag_close'] = $config['next_tag_close'] =
    $config['prev_tag_close'] = $config['last_tag_close'] =
    $config['num_tag_close'] = '</li>';
$config['prev_link'] = $config['next_link'] = '&laquo';

或者，如果您更喜欢 PHP 7 中的 list：

list($config['first_tag_open'], $config['last_tag_open'],
  $config['next_tag_open']) = array_fill(0, 3, '<li class="page-item">');
list($config['first_tag_close'], $config['next_tag_close'],
  $config['prev_tag_close'], $config['last_tag_close'],
  $config['num_tag_close']) = array_fill(0, 5,'</li>');

Answer 3

1. 在config文件夹中创建pagination.php文件

2. 将下面的代码放在pagination.php中

        <?php
            $config['full_tag_open'] = '<ul class="pagination">';
            $config['full_tag_close'] = '</ul>';
            $config['num_tag_open'] = '<li class="page-item">';
            $config['num_tag_close'] = '</li>';
            $config['cur_tag_open'] = '<li class="page-item active"><a class="page-link" href="#">';
            $config['cur_tag_close'] = '</a></li>';
            $config['next_tag_open'] = '<li class="page-item">';
            $config['next_tagl_close'] = '</a></li>';
            $config['prev_tag_open'] = '<li class="page-item">';
            $config['prev_tagl_close'] = '</li>';
            $config['first_tag_open'] = '<li class="page-item disabled">';
            $config['first_tagl_close'] = '</li>';
            $config['last_tag_open'] = '<li class="page-item">';
            $config['last_tagl_close'] = '</a></li>';
            $config['attributes'] = array('class' => 'page-link');    
   

   ?>

3. 控制器视图

    $total_users = $this->User_model->get_total_users(1,$search_text);
    $config['base_url'] = base_url().'manage/users/index/';
    $config['total_rows'] = $total_users;
    $config['per_page'] = 10;
   
    $this->pagination->initialize($config);
   

4. 输出如下
