Displaying previous posts and newer posts links

(@bloke)

I am trying to display the previous posts and newer post links. What is wrong with this code? It works but if I rename my query $wp_query to anything else it won’t display the previous posts link on the first page.

$temp = $wp_query; $wp_query= null;
		$wp_query = new WP_Query(); $wp_query->query('showposts=5' . '&paged='.$paged);

		while ($wp_query->have_posts()) : $wp_query->the_post();  ?><div id="postImage"><?php the_post_thumbnail(); ?></div>
    <h3><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a> </h3><span class="datePost"><?php  the_time('F j, Y') ;?></span>
<?php
the_excerpt();

 endwhile;

 if ($paged >1) { ?>

		<nav id="nav-posts">
			<div class="prev"><?php next_posts_link('&laquo; Previous Posts'); ?></div>
			<div class="next"><?php previous_posts_link('Newer Posts &raquo;'); ?></div>
		</nav>

		<?php } else { ?>

		<nav id="nav-posts">
			<div class="prev"><?php next_posts_link('&laquo; Previous Posts'); ?></div>
		</nav>

		<?php } ?>

There are notable syntax/format/PHP errors in the above. Please review else, endwhile, and well, all of it.

It works. What specific PHP errors are there? What specific syntax error? I got it straight from here so is their code wrong too? http://digwp.com/2013/01/display-blog-posts-on-page-with-navigation/
Changing all the references of “wp-query” to any other name should not keep it from working. I should be able to use any name for that.

I have to ask the question of where does this code reside?

On a custom template.

What theme are you using? Where did you download it from?

The next_posts_link() function needs another parameter to function properly for custom queries. See http://codex.wordpress.org/Function_Reference/next_posts_link#Usage_when_querying_the_loop_with_WP_Query
```
<?php
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
$the_query = new WP_Query(); $the_query->query( 'posts_per_page=5&paged='.$paged );

while ( $the_query->have_posts() ) : $the_query->the_post();  ?><div id="postImage"><?php the_post_thumbnail(); ?></div>
<h3><a href="<?php the_permalink(); ?>" rel="bookmark"><?php the_title(); ?></a> </h3><span class="datePost"><?php  the_time( 'F j, Y' ); ?></span>
<?php
the_excerpt();

endwhile;

if ( $paged > 1 ) { ?>

<nav id="nav-posts">
	<div class="prev"><?php next_posts_link( '« Previous Posts', $the_query->max_num_pages ); ?></div>
	<div class="next"><?php previous_posts_link( 'Newer Posts »' ); ?></div>
</nav>

<?php } else { ?>

<nav id="nav-posts">
	<div class="prev"><?php next_posts_link( '« Previous Posts', $the_query->max_num_pages ); ?></div>
</nav>

<?php } ?>
<?php wp_reset_postdata(); ?>
```

keesiemeijer thanks. That was the issue and now it works. Looking at that link I referenced above, is it because they used $wp_query , its not considered a custom query? In the link you supplied to the codex they don’t state it needs a second parameter to work.

The global $wp_query object contains all posts and other properties (e.g. total pages) for the current page request. ($wp_query is generated for all requests). The pagination functions use the $wp_query object to decide to display the pagination link or not. As the code in the link you referenced doesn’t make use of $wp_query the functions don’t know how many pages there are.
