WordPress: forcefully generate pagination url for 1st page - php

Question

I'm trying to generate pagination URL for first page. I used the following code.
get_pagenum_link(1); // gives http://www.website.com/
anyhow,
get_pagenum_link(2); // gives http://www.website.com/paged/2/
get_pagenum_link checks for the page # if($paged == 1) {// Don't include Page# in URL } I want to disable this check so that, it always include page #in URL
Also, http://www.website.com/paged/1/ is redirected to http://www.website.com/ I added a filter
add_filter('redirect_canonical','pif_disable_redirect_canonical');
function pif_disable_redirect_canonical($redirect_url) {
return false;
}
but, I think, its not a right way to do, it'll stop all canonical redirections.

Add this function into theme’s functions.php
function custom_pagination() {
if( is_singular() )
return;
global $wp_query;
/** Stop execution if there's only 1 page */
if( $wp_query->max_num_pages <= 1 )
return;
$paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
$max = intval( $wp_query->max_num_pages );
/** Add current page to the array */
if ( $paged >= 1 )
$links[] = $paged;
/** Add the pages around the current page to the array */
if ( $paged >= 3 ) {
$links[] = $paged - 1;
$links[] = $paged - 2;
}
if ( ( $paged + 2 ) <= $max ) {
$links[] = $paged + 2;
$links[] = $paged + 1;
}
echo '<div class="navigation"><ul>' . "\n";
/** Previous Post Link */
if ( get_previous_posts_link() )
printf( '<li>%s</li>' . "\n", get_previous_posts_link() );
/** Link to first page, plus ellipses if necessary */
if ( ! in_array( 1, $links ) ) {
$class = 1 == $paged ? ' class="active"' : '';
printf( '<li%s>%s</li>' . "\n", $class, esc_url( get_pagenum_link( 1 ) ), '1' );
if ( ! in_array( 2, $links ) )
echo '<li>…</li>';
}
/** Link to current page, plus 2 pages in either direction if necessary */
sort( $links );
foreach ( (array) $links as $link ) {
$class = $paged == $link ? ' class="active"' : '';
printf( '<li%s>%s</li>' . "\n", $class, esc_url( get_pagenum_link( $link ) ), $link );
}
/** Link to last page, plus ellipses if necessary */
if ( ! in_array( $max, $links ) ) {
if ( ! in_array( $max - 1, $links ) )
echo '<li>…</li>' . "\n";
$class = $paged == $max ? ' class="active"' : '';
printf( '<li%s>%s</li>' . "\n", $class, esc_url( get_pagenum_link( $max ) ), $max );
}
/** Next Post Link */
if ( get_next_posts_link() )
printf( '<li>%s</li>' . "\n", get_next_posts_link() );
echo '</ul></div>' . "\n";
}
Usage :
To call this function you have to add the below php code in your theme’s index.php, archive.php, category.php, or any other page template.
