Add pagination in wordpress admin in my own customized plugin [closed]

Answer 1

Generic pagination function.

This example looks like this on a large db:

<< Previous 1 2 3 4 5 6 7 8 9 ... 822 823 Next >>

or

<< Previous 1 2 ... 815 816 817 818 819 820 821 822 823 Next >>

or

<< Previous 1 2 ... 812 813 814 815 816 817 818 ... 822 823 Next >>

enjoy...

<?php 
/*Max Number of results to show*/
$max = 10;

//Get total records from db (change api to suit)

Answer 2

I solved this problem in different way. And solution is here

I use second option which has title "How To Add Pagination To WordPress Plugin?". This gives almost same pagination functionality as WordPress has.

Do not forget to download that "pagination.class.php" file, put it in your plugin folder and give appropriate path while including this file in your plugin.

Easy Steps :

$pagenum = isset( $_GET['pagenum'] ) ? absint( $_GET['pagenum'] ) : 1;

Find total numbers of records

$limit = 10; // number of rows in page
$offset = ( $pagenum - 1 ) * $limit;
$total = $wpdb->get_var( "SELECT COUNT(`id`) FROM {$wpdb->prefix}table_name" );
$num_of_pages = ceil( $total / $limit );

Give limit:

$entries = $wpdb->get_results( "SELECT * FROM {$wpdb->prefix}table_name LIMIT $offset, $limit" );

Add this code where you want pagination:

$page_links = paginate_links( array(
    'base' => add_query_arg( 'pagenum', '%#%' ),
    'format' => '',
    'prev_text' => __( '«', 'text-domain' ),
    'next_text' => __( '»', 'text-domain' ),
    'total' => $num_of_pages,
    'current' => $pagenum
) );

if ( $page_links ) {
    echo '<div class="tablenav"><div class="tablenav-pages" style="margin: 1em 0">' . $page_links . '</div></div>';
}
