Laravel is a very popular PHP development framework. Its powerful functions and excellent expansion capabilities have been favored by many developers. When developing based on Laravel, we often need to use the paging function, and Laravel also provides a very convenient paging class library - Laravel Pagination.
So, where is the Laravel paging file? This article will introduce you to the specific location and usage of Laravel paging files in detail.
Introduction to Laravel Pagination
Using the paging function in Laravel is very simple and can be easily achieved through the Pagination class library provided by Laravel. Laravel Pagination is a core class library of Laravel, and its files are located in the "/vendor/laravel/framework/src/Illuminate/Pagination/" directory.
How to use Laravel Pagination
Laravel Pagination provides a very rich API interface, and developers can choose to use different methods according to actual needs. Below we will introduce in detail how to use Laravel Pagination.
The basic usage of Laravel Pagination is very simple. You only need to add the paginate() method after the data query statement to achieve pagination. For example:
$users = DB::table('users')->paginate(10);
The above code means to obtain the data in the users table and display 10 pieces of data on each page. The paginate() method will automatically obtain the current page number based on the request parameters. If no parameters are specified, it will default to the first page.
When using Laravel Pagination, we can customize the style of the pagination page through the simple style code provided by the blade template engine. For example:
<div class="pagination"> {{ $users->links() }} </div>
The above code will display the pagination results in a div container with a "pagination" class. We can also use Laravel to make more flexible custom styles. The specific method is as follows:
{!! $users->render() !!}
In the above code, we use the {!! !!} identifier in Laravel's blade template engine, In this way, Laravel will output the html code to the page intact, thereby realizing a custom paging style.
When using Laravel Pagination, getting paging data is a very important operation. The following code demonstrates how to use Laravel Pagination to obtain paginated data:
@foreach ($users as $user) {{ $user->name }} @endforeach
The above code will output each piece of data in the query results in turn, and can be processed using Laravel's template syntax, such as formatting the data, Judgment, loop and other operations.
In actual development, some pages need to display a larger amount of data, while other pages only need to display a small amount of data. . In this case, we can customize the amount of data displayed on each page through the perPage() method provided by Laravel Pagination, for example:
$users = DB::table('users')->paginate(5);
The above code means that only 5 pieces of data are displayed on each page.
The default paging parameter name used by Laravel Pagination is "page". What if we need to use other parameter names? At this time, we can use the three parameters provided by Laravel Pagination to customize the paging parameter name, for example:
$users = DB::table('users')->paginate(10, ['*'], 'custom_page_name');
The above code indicates using the custom parameter name "custom_page_name" as the paging parameter name.
Summary
Laravel Pagination is one of the very important class libraries in the Laravel framework. It provides a very convenient paging function and can help us easily achieve the paging effect. When using Laravel Pagination, we need to pay attention to its specific location and usage in order to develop Laravel applications more flexibly and efficiently.
