WP_Query & pagination not working

Might make sure you are using proper pagination. Here’s an example:

<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('cat=1&posts_per_page='.get_option('posts_per_page').'&paged=' . $paged);
?>

Thanks Michael..

Tried that but with no effect.. here’s the new code (properly stripped back this time)..

<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$my_query = new WP_Query();
$my_query->query('category_name=news&posts_per_page='.get_option('posts_per_page').'&paged=' . $paged);
?>

<?php if ($my_query->have_posts()) : ?>

	<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>

		<div id="post-<?php the_ID() ?>" class="<?php thematic_post_class() ?>">

		<!-- do stuff -->

		</div><!-- .post -->

	<?php endwhile; ?>

	<div class="nav-previous"><?php next_posts_link(__('<span class="meta-nav">&laquo;</span> Older posts', 'thematic')) ?></div>
	<div class="nav-next"><?php previous_posts_link(__('Newer posts <span class="meta-nav">&raquo;</span>', 'thematic')) ?></div>

<?php endif; ?>

Any ideas?

ok, I fixed it ..

In the code above you’ll see that I named my new instance of the WP_Query object $my_query.. that’s the problem.

The code in the internal wordpress functions next_posts_link & previous_posts_link expect the query object to be called $wp_query. Once I renamed my object it all started working.

This is confusing since a number of other support tickets around this subject have supposedly working code examples with an object name other than $wp_query ($my_query being an explicit one of these).

Anyhoo.. the working code is..

<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$wp_query = new WP_Query();
$wp_query->query('category_name=news&posts_per_page='.get_option('posts_per_page').'&paged=' . $paged);
?>

<?php if ($wp_query->have_posts()) : ?>

	<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>

		<div id="post-<?php the_ID() ?>" class="<?php thematic_post_class() ?>">

		<!-- do stuff -->

		</div><!-- .post -->

	<?php endwhile; ?>

	<div class="nav-previous"><?php next_posts_link(__('<span class="meta-nav">&laquo;</span> Older posts', 'thematic')) ?></div>
	<div class="nav-next"><?php previous_posts_link(__('Newer posts <span class="meta-nav">&raquo;</span>', 'thematic')) ?></div>

<?php endif; ?>

Hi ..

I am facing the same problem and the above solution is not working for me ??

I m getting 404 page when I click on page 2 or 3 … here is my code

$catID = get_query_var(‘cat’);
$catName = strtolower(get_cat_name($catID));

$paged = (get_query_var(‘paged’)) ? get_query_var(‘paged’) : 1;
$wp_query = new WP_Query();
$wp_query->query(“category_name=$catName&paged=$paged&posts_per_page=1”);

<?php if ($wp_query->have_posts()) : ?>
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
// data ..
<?php endwhile; ?>
<?php endif; ?>

Any help!

Thanks
Ashish

$catID = get_query_var('cat');
$catName = strtolower(get_cat_name($catID));

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$wp_query = new WP_Query("category_name=$catName&paged=$paged&posts_per_page=1");

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
// data ..
<?php endwhile; ?>
<?php endif; ?>

Try this.

Thanks for your reply.

I have tried this as well but it is still NOT working ??

More info …

I am on archive.php where I m showing posts related to passed category i.e. (?cat=[num] in the query string)

The default page is coming and showing the first records (I have set post_per_page to 1) and also showing 5 pages in page nav. When I click on page 2/3/4/5 it shows a 404 page ??

Hope I am a bit clear this time.

maybe

new WP_Query("category_name=$catName&paged=$paged&posts_per_page=1");

to:

new WP_Query("category_name=$catName&paged='. $paged .'&posts_per_page=1");

?
see
'&paged=' . $paged

Hello everyone,

I’m also getting a 404 error everytime i click on another page number :S

Here’s my current post query:

<?php query_posts(array('post_type'=>array('post','jogos','videos'),'posts_per_page'=>6, 'paged=>' . $paged )); while (have_posts()) : the_post(); ?>

I tried adding the paged thing but it didn’t work :S

Thanks in advance,
Tiago

THANK YOU SO MUCH!
Just spend 3 hours trying to figure out what was wrong but that fixed it…

$catID = get_query_var('cat');
	$catName = strtolower(get_cat_name($catID));

	$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
	$wp_query = new WP_Query("category_name=$catName&paged=$paged&posts_per_page=1");

THANK kathatp.

But this work only in this private case.
If posts_per_page is change or delete word but with all Categories.

I diggin in my head how to fix that because two of objects is not working proper. My decision is…

Put this in function.php

function my_posts_nav_link( $type = '', $label = '',  $maxPageNum = '' ) {
	$args = array_filter( compact('type', 'label', 'maxPageNum') );
	echo my_get_posts_nav_link($args);
}

function my_get_posts_nav_link($args = array()) {
	$return = '';
	$defaults = array(
		'maxPageNum' => '0',
	);
	$max_num_pages = $args['maxPageNum'];
	$args = wp_parse_args( $args, $defaults );
	$paged = get_query_var('paged');
	if ( $max_num_pages > 1 ) {
		if ($args['type'] == "next") {
			$return = get_previous_posts_link($args['label']);
		}
		if ($args['type'] == "prev") {
			$return = my_get_next_posts_link($args['label'], $max_num_pages);
		}
	}
	return $return;
}

function my_get_next_posts_link( $label = 'Next Page »', $max_page = 0 ) {
	global $paged, $wp_query;
	if ( !$paged ) {
		$paged = 1;
	}
	$nextpage = intval($paged) + 1;
	if ( !is_single() && ( empty($paged) || $nextpage <= $max_page) ) {
		$attr = apply_filters( 'next_posts_link_attributes', '' );
		return '<a href="' . next_posts( $max_page, false ) . "\" $attr>" . preg_replace('/&([^#])(?![a-z]{1,8};)/i', '&$1', $label) . '</a>';
	}
}

and call with
my_posts_nav_link('next','Newer',''.$queryObject->max_num_pages.'');
