All posts on page of one category - wordpress

Question

I really can't figure this out. I'm trying to have posts all posts on a page from one category, but I still get all categories. This is the code I'm using now. I thought I could manage with WP_Query( array( 'posts_per_page' => -1, 'category_name' => 'resep' ) );, but it totally drives me nuts.
<?php /* Template Name: Blog */ ?>
<?php get_header(); ?>
<div id="content-wrap">
<div id="content">
<div class="post_content">
<h1 class="archive_title"><?php the_title(); ?></h1>
<?php
$query['post_type'] = 'post';
// WP 3.0 PAGED BUG FIX
if ( get_query_var('paged') )
$paged = get_query_var('paged');
elseif ( get_query_var('page') )
$paged = get_query_var('page');
else
$paged = 1;
//$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$query['paged'] = $paged;
$recipe_posts = new WP_Query( array( 'posts_per_page' => -1, 'category_name' => 'resep' ) );
while ( $recipe_posts->have_posts() ) { $recipe_posts->the_post(); }
query_posts($query);
if (have_posts()) : ?>
<?php $more = 0; ?>
<div class="posts">
<?php while (have_posts()) : the_post();
$is_recipe = in_category('Resep'); ?>
<div id="post-<?php the_ID(); ?>" <?php post_class('clearfix'); ?>>
<?php if (option::get('index_thumb') == 'on') {
get_the_image( array( 'size' => 'loop', 'width' => option::get('thumb_width'), 'height' => option::get('thumb_height'), 'before' => '<div class="post-thumb">', 'after' => '</div>' ) );
} ?>
<div class="details">
<h2 class="title"><?php the_title(); ?></h2>
<?php if ( option::get('display_meta') == 'on' ) { ?>
<div class="meta">
<?php
if ( $is_recipe ) {
$fields = get_fields();
if ( !empty( $fields ) ) echo $fields;
} else { ?>
<p><strong><img src="<?php echo get_template_directory_uri() . '/images/person.png'; ?>" /><?php _e('Author', 'wpzoom'); ?>:</strong><?php the_author_posts_link(); ?></p>
<p><strong><img src="<?php echo get_template_directory_uri() . '/images/clock.png'; ?>" />
<?php _e('Posted', 'wpzoom'); ?>
:</strong> <?php echo get_the_date(); ?></p>
<?php } ?>
</div>
<?php } ?>
<div class="entry">
<?php the_content('<span>'.__('Read More', 'wpzoom').' ›</span>'); ?>
</div>
<p>
<?php if ( option::get('display_readmore') == 'on' && (option::get('display_content') == 'Excerpt') ) { ?>
<a href="<?php the_permalink(); ?>" class=" clean more-link">
<?php _e( ( $is_recipe ? 'Lihat Resep' : 'Read More' ), 'wpzoom' ); ?>
</a>
<?php } ?>
<?php edit_post_link( __('Edit', 'wpzoom'), ' <small>', '</small>' ); ?>
</p>
</div>
<div class="cleaner"> </div>
</div>
<!-- /.post -->
<?php endwhile; ?>
</div>
<div class="cleaner"> </div>
<?php get_template_part( 'pagination' ); ?>
<?php wp_reset_query(); ?>
<div class="cleaner"> </div>
<?php endif; ?>
</div><!-- / .post_content -->
</div><!-- / #content -->
<?php get_sidebar(); ?>
</div>
<?php get_footer(); ?>

Answer 1

You're making it far too complex, just specificy the stuff you need inside the while loop:
$recipe_posts = new WP_Query( array( 'posts_per_page' => -1, 'category_name' => 'resep' ) );
while ( $recipe_posts->have_posts() ) {
$recipe_posts->the_post();
echo '<li>' . get_the_title() . '</li>';
}
wp_reset_query();

Answer 2

You have entered loop inside loop, try this following with cleaning your code:
$args = array('posts_per_page' => -1 , 'category_name' => 'resep');
$recipe_posts = new WP_Query($args);
if($recipe_posts->have_posts()) :
while($recipe_posts->have_posts()) :
$recipe_posts->the_post();
?>
<h1><?php the_title() ?></h1>
<div class='post-content'><?php the_content() ?></div>
<?php
endwhile;
else:
?>
Oops, there are no posts.
<?php
endif;
?>

Answer 3

I cleaned the whole template, but posts from other categories were still there. In the end I managed with these lines
global $wp_query;
$args = array_merge( $wp_query->query, array( 'category_name' => 'resep' ) );
query_posts( $args );
$recipe_posts = new WP_Query($args);
$more = 0;
if($recipe_posts->have_posts()) :
while ($recipe_posts->have_posts()) : $recipe_posts->the_post();?>
