    Hi, i want to display my blog in a different page, not in index, and i want to show only the posts on a certain category.
    I placed ‘cat=7’ but it is not working, it shows all the post as the category was not specify :S

    This is my code:

    <article>
	<?php
	$temp = $wp_query;
	$wp_query= null;
	$wp_query = new WP_Query('cat=7');
	$wp_query->query('showposts=5' . '&paged='.$paged);
	while ($wp_query->have_posts()) : $wp_query->the_post();
	?>
	<div class="post">
		<h2><a href="<?php the_permalink(); ?>" title="Read more"><?php the_title(); ?></a></h2>
		<p><?php echo substr(get_the_excerpt(), 0,300); ?></p>
	</div>
	<?php endwhile; ?>

	<?php if ($paged > 1) { ?>
	<nav id="nav-posts">
	<div><?php next_posts_link(' Previous'); ?></div>
	<div><?php previous_posts_link('Next'); ?></div>
	</nav>
	<?php } else { ?>
		<nav id="nav-posts">
		<div><?php next_posts_link('Previous '); ?></div>
	        </nav>
	<?php } ?>

	<?php wp_reset_postdata(); ?>
</article>

    Thanks a lot for your time.

    Try it with this:

    <article>
	<?php
	$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
	$temp = $wp_query;
	$wp_query= null;
	$wp_query = new WP_Query();
	$args = array(
		'posts_per_page' => 5,
		'cat'            => 7,
		'paged'          => $paged,
	);
	$wp_query->query( $args );
	while ( $wp_query->have_posts() ) : $wp_query->the_post();
?>
	<div class="post">
		<h2><a href="<?php the_permalink(); ?>" title="Read more"><?php the_title(); ?></a></h2>
		<p><?php echo substr( get_the_excerpt(), 0, 300 ); ?></p>
	</div>
	<?php endwhile; ?>

	<?php if ( $paged > 1 ) { ?>
	<nav id="nav-posts">
	<div><?php next_posts_link( ' Previous' ); ?></div>
	<div><?php previous_posts_link( 'Next' ); ?></div>
	</nav>
	<?php } else { ?>
		<nav id="nav-posts">
		<div><?php next_posts_link( 'Previous ' ); ?></div>
	        </nav>
	<?php } ?>
	<?php wp_reset_postdata(); ?>
	<?php $wp_query = null; $wp_query = $temp; ?>
</article>

    keesiemeijer, thanks a lot, that works perfectly.
    Anyway, I was checking other posts, and i found this, which helped, although it does not use wp_query.

    <article>
	<?php

		'posts_per_page' => 5,
		'paged' => $paged
	);
	query_posts($args);
	while ($wp_query->have_posts()) : $wp_query->the_post();
	?>
	<div class="post">
		<h2><a href="<?php the_permalink(); ?>" title="Read more"><?php the_title(); ?></a></h2>
		<p><?php echo substr(get_the_excerpt(), 0,300); ?></p>

    $wp_query->query( $args ); is essentially the same as query_posts($args);
    To clean up after a call to query_posts, make a call to wp_reset_query() instead of wp_reset_postdata();

    I’m glad you’ve got it resolved.
