How to Add Numeric Pagination in Your WordPress Theme

This hack will show you how to add numeric pagination in your WordPress theme 생일 케이크 사진 다운로드. The goal is to replace the default Older and Newer pagination links at the bottom of archive pages with easy to navigate page numbers.

First we will show you how to manually add numeric pagination in your WordPress themes. This will benefit our advanced users, and users who are learning theme development, or want to do this without relying on a third party plugin. Lets get started by adding the following code in your theme’s functions.php file.

function wpbeginner_numeric_posts_nav() {

	if( is_singular() )

	global $wp_query;

	/** Stop execution if there's only 1 page */
	if( $wp_query->max_num_pages <= 1 )

	$paged = get_query_var( 'paged' )  다운로드? 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><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 ? '' : '';

		printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( 1 ) ), '1' );

		if (  다운로드! 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 ? '' : '';
		printf( '<li%s><a href="%s">%s</a></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 ? '' : '';
		printf( '<li%s><a href="%s">%s</a></li>'  다운로드. "\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";


To add this in your templates, you will have to add the following template tag in your theme’s index.php, archive.php, category.php, and any other archive page template.

<?php wpbeginner_numeric_posts_nav(); ?>

.navigation li a,
.navigation li a:hover,
.navigation li.active a,
.navigation li.disabled {
	color: #fff;

.navigation li {
	display: inline;

.navigation li a,
.navigation li a:hover,
.navigation li.active a,
.navigation li.disabled {
	background-color: #6FB7E9;
	border-radius: 3px;
	cursor: pointer;
	padding: 12px;
	padding: 0.75rem;

.navigation li a:hover,
.navigation li.active a {
