How to implement data paging function in ThinkPHP 5

ThinkPHP 5 is an excellent PHP framework that provides rich functions and good documentation support, especially in data paging, it provides a complete set of solutions. In this article, we will introduce how to implement data paging functionality in ThinkPHP 5.

1. Configure paging parameters

In the application's config.php configuration file, you can configure the default paging parameters. The following are some commonly used examples:

'paginate' => [
    'type'     => 'bootstrap',
    'var_page' => 'page',
    'list_rows'=> 15,
],

The above configuration will use Bootstrap style paging and display 15 pieces of data per page.

2. Building query statements

In the controller, we need to perform data query and add paging information to the query. The following are some basic queries:

public function articleList()
{
    $list = Db::name('article')->paginate(10);
    $page = $list->render();
    $this->assign('list',$list);
    $this->assign('page',$page);
    $this->assign('count',$list->total());

    return $this->fetch('article_list');
}

In the above code, we use the paginate() method of the Db class to perform data query, and set the number of records displayed on each page to 10. Then, we get the pagination HTML code by calling the render() method and pass the pagination information and data to the view.

3. Display paging in the view file

Finally, we need to display the paging information in the view file and add styles to the paging information. The following is a basic paging template:

<div class="pagination pull-right">
    <ul>
        {$page}
    </ul>
</div>

共{$count}条记录，每页展示{$list->listRows}条数据。

In the above code, we implement the basic paging HTML code by nesting it in a UL tag and placing it in a DIV container. Pagination display effect.

Final summary: ThinkPHP 5 provides a simple paging function, which we can achieve by adding parameters in data queries and setting default parameters in configuration files. Of course, you can also customize the paging method and style according to actual needs to achieve better user experience and operational effects.
