Posts mais antigos não são mostrados

rogerio de paulo · Setembro 20, 2010

E ai Galera

Estou com um dificuldade e gostaria da ajuda de vocês.

Estou fazendo um site e na pagina inicial deixei para ser exibido apenas as 3 ultimas postagens e mostrar somente de uma determinada categoria.

Porem quando eu uso o codigo

<?php query_posts('cat=1'); ?>

que faz mostrar somente os posts da categoria 1, ao clicar-se no botão "Mostrar posts mais antigos" os posts mais antigos não são mostrados, fica travado nos 3 ultimos posts.

Porem se eu retirar o o codigo "<?php query_posts('cat=1'); ?>" eu consigo mostrar os posts mais antigos porem aparece as outras categorias que não podem aparecer.

Estou usando o wordpress 3.0 e o thema que vem padrão no wordpress 3.0 o thema "Twenty Ten 1.0" porem modifiquei para ficar da forma que preciso.

Alguem poderia dar uma idéia sobre o que posso fazer.

Abaixo está um pedaço do código para terem uma ideia.

<?php
	/* Start the Loop.
	 *
	 * In Twenty Ten we use the same loop in multiple contexts.
	 * It is broken into three main parts: when we're displaying
	 * posts that are in the gallery category, when we're displaying
	 * posts in the asides category, and finally all other posts.
	 *
	 * Additionally, we sometimes check for whether we are on an
	 * archive page, a search page, etc., allowing for small differences
	 * in the loop on each template without actually duplicating
	 * the rest of the loop that is shared.
	 *
	 * Without further ado, the loop:
	 */ ?>
	 
<?php query_posts('cat=1'); ?>
	 
<?php while ( have_posts() ) : the_post(); ?>


<?php /* How to display posts in the Gallery category. */ ?>

	<?php if ( in_category( _x('gallery', 'gallery category slug', 'twentyten') ) ) : ?>
		<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
			<h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>

			<div class="entry-meta">
				<?php twentyten_posted_on(); ?>
			</div><!-- .entry-meta -->

			<div class="entry-content">
<?php if ( post_password_required() ) : ?>
				<?php the_content(); ?>
<?php else : ?>
				<div class="gallery-thumb">
<?php
	$images = get_children( array( 'post_parent' => $post->ID, 'post_type' => 'attachment', 'post_mime_type' => 'image', 'orderby' => 'menu_order', 'order' => 'ASC', 'numberposts' => 999 ) );
	$total_images = count( $images );
	$image = array_shift( $images );
	$image_img_tag = wp_get_attachment_image( $image->ID, 'thumbnail' );
?>
					<a class="size-thumbnail" href="<?php the_permalink(); ?>"><?php echo $image_img_tag; ?></a>
				</div><!-- .gallery-thumb -->
				<p><em><?php printf( __( 'This gallery contains <a %1$s>%2$s photos</a>.', 'twentyten' ),
						'href="' . get_permalink() . '" title="' . sprintf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ) . '" rel="bookmark"',
						$total_images
					); ?></em></p>

				
<?php endif; ?>

Query_post funciona também com combinação de parâmetros Ex:

<?php query_posts('cat=1&show_posts=10&exclude='); ?>

Mas esse lance de ver posts mais antigos não é relacionado a paginação do tema? (Página 1 2 3 4 5 de 15 Páginas)?

O Wordpress até tem uma função para puxar essa paginação

<?php posts_nav_link(); ?>

http://codex.wordpress.org/Next_and_Previous_Links

E ai Anderson, beleza meu irmão

O tema que estou usando não usa o <?php posts_nav_link(); ?>

Vou postar abaixo o codigo que creio que faça essa questão da paginação, se tiver alguma ideia sobre o que posso mudar ficarei muito grato.

Lembrando que estou usando o <?php query_posts('cat=1'); ?>

<?php /* Display navigation to next/previous pages when applicable */ ?>

<?php if ( $wp_query->max_num_pages > 1 ) : ?>

<div id="nav-below" class="navigation">

<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">←</span> Older posts', 'twentyten' ) ); ?></div>

<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">→</span>', 'twentyten' ) ); ?></div>

</div>

<?php endif; ?>

<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">←</span> Older posts', 'twentyten' ) ); ?></div>

<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">→</span>', 'twentyten' ) ); ?></div>

Já tentou alterar o mx_num_pages 1? Colocando um numero maior de páginas ex:

<?php if ( $wp_query->max_num_pages > 1000 ) : ?>

Só para ver o que acontece.. se não explodir o pc beleza :D

rogerio de paulo · Setembro 23, 2010

E ai Anderson

Já alterei sim o valor de max_num_pages para um numero grande, porem não resolveu.

A unica coisa que funciona para mostrar os posts mais antigos é se eu tirar a linha " <?php query_posts('cat=1'); ?> " porem sem essa linha de codigo aparece as outras categorias de posts que não podem aparecer.

Cara, vou postar abaixo o codigo completo dessa pagina. Se voce puder fazer o favor de analisar e ver se consegue encontrar alguma coisa, seria ótimo.

<?php

/**

* The loop that displays posts.

*

* The loop displays the posts and the post content. See

* http://codex.wordpress.org/The_Loop to understand it and

* http://codex.wordpress.org/Template_Tags to understand

* the tags used in it.

*

* This can be overridden in child themes with loop.php or

* loop-template.php, where 'template' is the loop context

* requested by a template. For example, loop-index.php would

* be used if it exists and we ask for the loop with:

* <code>get_template_part( 'loop', 'index' );</code>

*

* @package WordPress

* @subpackage Twenty_Ten

* @since Twenty Ten 1.0
