WP_LIST_TABLE - complete code for searching, listing, pagination

WP_LIST_TABLE - complete code for searching, listing, pagination:

1. First register a menu to maintain a view:

<?php
require_once 'class-people-list-table.php';

add_action( 'admin_menu', 'ashique_register_custom_menu_page' );
function ashique_register_custom_menu_page()
{
    $parent_slug = 'ashique-slug';
    $capability = 'manage_options';

    add_menu_page(
        'Title',
        'Menu Title',
        $capability,
        $parent_slug,
        'ashique_dashbard_callback',
        'dashicons-dashboard',
        6
    );

    add_submenu_page(
        $parent_slug,
        'Dashboard',
        'Dashboard',
        $capability,
        $parent_slug,
        'ashique_dashbard_callback',
    );

    add_submenu_page(
        $parent_slug,
        'People List',
        'People List',
        $capability,
        'ashique-people-list',
        'ashique_people_list_callback',
    );
}

2. Now maintain list callback function:

function ashique_people_list_callback()
{
    // Creating an instance of People_List_Table
    $people_list_table = new People_List_Table();
    $people_list_table->prepare_items();

    ?>
    <div class="wrap">
        <h2>People List Table</h2>

        <form method="get">
            <input type="hidden" name="page" value="<?php echo $_REQUEST['page']; ?>" />
            <?php $people_list_table->search_box('Search', 'search_id'); ?>
        </form>

        <form method="post">
            <input type="hidden" name="page" value="my_list_test" />
            <?php $people_list_table->display(); ?>
        </form>
    </div>
    <?php
}

3. List table class file code:

<?php
if (!class_exists('WP_List_Table'))
{
    require_once ABSPATH . 'wp-admin/includes/class-wp-list-table.php';
}

class People_List_Table extends WP_List_Table
{
    // Define table columns
    function get_columns()
    {
        $columns = array(
            'id'               => 'ID',
            'name'             => 'Name',
            'email'       => 'Email',
        );
        return $columns;
    }

    // Get table data
    private function get_table_data($args = [])
    {
        global $wpdb;
        $people_table = $wpdb->prefix . 'people';

        $search = $args['s'];
        $offset = $args['offset'];
        $number = $args['number'];

        if ($search != '')
        {
            $sql = "SELECT id, name, email
                FROM $people_table
                WHERE
                name LIKE '%$search%'
                OR
                email LIKE '%$search%'
                ORDER BY email
                LIMIT $offset, $number";
        }
        else
        {
            $sql = "SELECT id, name, email
                FROM $people_table
                ORDER BY email
                LIMIT $offset, $number";
        }

        return $wpdb->get_results($sql, ARRAY_A);
    }

    private function get_table_data_total_rows($args = [])
    {
        $search = $args['s'];
        global $wpdb;
        $donar_table = $wpdb->prefix . 'people';

        if ($search != '')
        {
            $sql = "SELECT id, name, email
                FROM $people_table
                WHERE
                name LIKE '%$search%'
                OR
                email LIKE '%$search%'
                ORDER BY name";
        }
        else {
            $sql = "SELECT id, name, email
            FROM $people_table
            ORDER BY name";
        }
       
        return count($wpdb->get_results($sql, ARRAY_A));
    }

    function column_default($item, $column_name)
    {
        switch ($column_name)
        {
        case 'name':
        case 'email':
        default:
            return $item[$column_name];
        }
    }

    // Bind table with columns, data and all
    function prepare_items()
    {
        //data
        $per_page = 30;
        $current_page = $this->get_pagenum();

        // TODO: Implement your search logic here
        $search = (isset($_REQUEST['s'])) ? sanitize_text_field($_REQUEST['s']) : '';

        $args = array(
            'offset' => ($current_page - 1) * $per_page,
            'number' => $per_page,
            's' => $search,
        );

        // TODO: Implement your data retrieval logic based on $args
        $data = $this->get_table_data($args); // Replace with your data array
        $total_items = $this->get_table_data_total_rows($args); // Replace with your data array

        $this->set_pagination_args(array(
            'total_items' => $total_items,
            'per_page' => $per_page,
        ));

        $columns = $this->get_columns();
        $hidden = array();
        $sortable = array();

        $this->_column_headers = array($columns, $hidden, $sortable);

        $this->items = $data;
    }
}
