WP List Table Tutorial – Add Pagination To Data List

Share this Article

We create wordpress admin tables using WP_List_Table class to show data. Suppose we have large amount of data. To show data into a perfect format we need some pagination kind of feature. This class also provides method to add pagination. In this tutorial we will see how to add data pagination to WordPress admin table.

Data pagination means data will come according to pagination settings. This is also a bit logical implementation you need to focus on.

Probably while working with wordpress admin tables of Post, Pages, Users, etc you may or may not seen this pagination. This pagination works on the basis of rows available to list table.

We will see here how to add pagination to wordpress admin table.

Add Pagination to List Table

WP_List_Table class provides a method to add data pagination feature to list tables. Assuming we are adding data pagination to users data.

In this last tutorials we have seen how to show users data into list table.

/* pagination */
$per_page = 2;
$current_page = $this->get_pagenum();
$total_items = count($this->users_data);

$this->users_data = array_slice($this->users_data, (($current_page - 1) * $per_page), $per_page);

      'total_items' => $total_items, // total number of items
      'per_page'    => $per_page // items to show on a page

$per_page = 2 means total 2 rows will show on each page.

$this->get_pagenum(), method is provided by WP_List_Table class. It returns the current page number. Like for first page it will be 1, for second page it will be 2 and so on.

array_slice(), it’s a PHP function which picks data on the basis of start index.

$this->set_pagination_args(), method is provided by WP_List_Table class. It takes values in an array. Array values are like count of total items and how many rows on each page.

This is the only whole concept we need to add inside prepare_items() method to add pagination. That’s it.
