如何创建分页的url参数在codeigniter？ [英] how to create pagination for url with parameters in codeigniter?

问题描述

我们有一个基于某些参数（例如 domain.com/index.php/welcome/student/male ）的页面结果的应用程序 welcome 是控制器学生是方法名男性是参数，现在我们要分页这个，但问题是一个人也可以使用子类别像这样 domain.com/index.php/welcome/student/male/steven 其中 steven 是另一个参数，如何为此类型的网址创建分页。提前感谢：）

Thank you in advance :)

推荐答案

有可选参数和分页时的一些问题：

Some problems when having optional parameters along with pagination:

1. 根据提供的参数的
   编号，在网址中放置分页偏移变化。


2. 如果可选参数不是

方法1： >
使用查询字符串进行分页：

Method 1:
Use query strings for pagination:

function student($gender, $category = NULL) {
    $this->load->library('pagination');
    $config['page_query_string'] = TRUE;
    $config['query_string_segment'] = 'offset';

    $config['base_url'] = base_url().'test/student/'.$gender;
    // add the category if it's set
    if (!is_null($category)) 
        $config['base_url'] = $config['base_url'].'/'.$category;

    // make segment based URL ready to add query strings
    // pagination library does not care if a ? is available
    $config['base_url'] = $config['base_url'].'/?';


    $config['total_rows'] = 200;
    $config['per_page'] = 20;
    $this->pagination->initialize($config);

    // requested page:
    $offset = $this->input->get('offset');

    //...
}

方法2：

假设类别永远不是一个数字，如果最后一个段是一个数值，那么它的分页偏移量函数的参数：

Method 2:
Assuming the category would never be a number and if the last segment is a numeric value then it's the pagination offset not a function's parameter:

function student($gender, $category = NULL) {
    // if the 4th segment is a number assume it as pagination rather than a category
    if (is_numeric($this->uri->segment(4))) 
        $category = NULL;

    $this->load->library('pagination');
    $config['base_url'] = base_url().'test/student/'.$gender;
    $config['uri_segment'] = 4;

    // add the category if it's set
    if (!is_null($category)) {
        $config['uri_segment'] = $config['uri_segment'] + 1;
        $config['base_url'] = $config['base_url'].'/'.$category;
    }

    $config['total_rows'] = 200;
    $config['per_page'] = 20;
    $this->pagination->initialize($config);

    // requested page:
    $offset = ($this->uri->segment($config['uri_segment'])) ? $this->uri->segment($config['uri_segment']) : 1;

    //...
}   

第一种方法，因为它不干扰函数参数，并且将更容易在抽象层面实现分页支持。

I prefer the first method because it does not interfere with function parameters and it would be easier to implement the pagination support at an abstract level.
