In Laravel, pagination is a very commonly used function. Laravel provides a convenient pagination class that can easily implement pagination. However, in some cases, we may need to add more attributes to the paginated results, such as the total number of records or search keywords. In this article, we will explore how to add custom properties for paginated results in Laravel.

First, let’s take a quick look at the paging functionality in Laravel. We can use the paginate() method to get paginated data from the database, for example:

$users = DB::table('users')->paginate(10);

This code will get 10 entries from the database table named users records and organize them into pages with 10 records per page. We can now render these records in a view and display pagination links below the page numbers.

However, sometimes we need to add more attributes to the paginated results, such as the total number of records. To achieve this, we can use Laravel's query builder. Consider the following code:

$users = DB::table('users')->select(\DB::raw('count(*) as total'))->paginate(10);

In this example, we have added a select clause to the query builder which will return a column named total , its value is the total number of rows in the query results. Now, we can access this property in the view like this:

{{ $users->total }}

Similarly, we can add other properties using the query builder. For example, if we want to add search keywords to the paginated results, we can modify the above example code as follows:

$keyword = 'John';
$users = DB::table('users')
            ->select(\DB::raw('count(*) as total'))
            ->where('name', 'like', "%{$keyword}%")
            ->paginate(10);
$users->keyword = $keyword;

In this example, we have added another query builder function where, it will return only rows containing the name of the keyword John in the results. We then store the keyword in a custom property keyword of the $users object, allowing us to access it in the view:

{{ $users->keyword }}

this way , we can add any number and type of properties to the paginated results. Note that we can access these custom properties by accessing the public properties of the paginated results object.

In this article, we discussed how to add custom properties for paginated results in Laravel. We achieve this using the select and where functions in the query builder. These methods work not only with the paginate() function, but also with other query builder functions.
