Sto cercando difarein modo che lamiapagina dellenotizie visualizzii contenuti di una sola categoria (numero 3)manon riesco afarlofunzionare. Invece di visualizzare soloi post della categoria 3,mostrai post ditutte le categorie.

Eccoilmio codice:

 <?php get_header(); ?>

            <div class="content news_page">

                       <h1>Latest News</h1>     

                       <?php $args = array(
                            'post_type' => 'post' ,
                            'orderby' => 'date' ,
                            'order' => 'DESC' ,
                            'posts_per_page' => 6,
                            'category'         => '3',
                            'paged' => get_query_var('paged'),
                            'post_parent' => $parent
                       ); ?>
                       <?php query_posts($args); ?>




                       <?php if ( have_posts() ) : ?>
                            <?php while ( have_posts() ) : the_post(); ?>

                                <div class="large-4 medium-4 small-12 columns">
                                    <div class="latest_news_cont">
                                    <a href="<?php the_permalink() ?>"><?php the_post_thumbnail(); ?></a>

                                    <a href="<?php the_permalink() ?>"><h5><?php the_title(); ?></h5></a>
                                    <?php the_excerpt(); ?>
                                    <p style="text-align:center;"><a href="<?php the_permalink() ?>" class="readmore_news">Read more</a></p>
<br>
<div class="clear"></div>
                                       </div>
                                    </div>

                            <?php endwhile; ?>
                        <?php endif; ?>


<div class="clear"></div>

            </div><!--end of content-->



<div class="clear"></div>

<?php get_footer(); ?>

I'm trying to get my news page to display content from one category only (number 3) but I cant seem to get it to work. Instead of just displaying posts from category 3 it displays posts from all category's.

Here is my code:

<?php get_header(); ?>

            <div class="content news_page">

                       <h1>Latest News</h1>     

                       <?php $args = array(
                            'post_type' => 'post' ,
                            'orderby' => 'date' ,
                            'order' => 'DESC' ,
                            'posts_per_page' => 6,
                            'category'         => '3',
                            'paged' => get_query_var('paged'),
                            'post_parent' => $parent
                       ); ?>
                       <?php query_posts($args); ?>




                       <?php if ( have_posts() ) : ?>
                            <?php while ( have_posts() ) : the_post(); ?>

                                <div class="large-4 medium-4 small-12 columns">
                                    <div class="latest_news_cont">
                                    <a href="<?php the_permalink() ?>"><?php the_post_thumbnail(); ?></a>

                                    <a href="<?php the_permalink() ?>"><h5><?php the_title(); ?></h5></a>
                                    <?php the_excerpt(); ?>
                                    <p style="text-align:center;"><a href="<?php the_permalink() ?>" class="readmore_news">Read more</a></p>
<br>
<div class="clear"></div>
                                       </div>
                                    </div>

                            <?php endwhile; ?>
                        <?php endif; ?>


<div class="clear"></div>

            </div><!--end of content-->



<div class="clear"></div>

<?php get_footer(); ?>

Personalmente lofareipiuttosto.

Invece di:

'category' => '3',

Sostituiscilo con questo:

'category_name' => 'my-category-slug'

Ovviamentetrovailnome dellatua categoria sluge sostituisci "my-category-slug".

Comemenzionato da @ s-ha-dum,sarebbemeglionon usare questometodoe piuttosto usareilmetodo WP_Query.Puoi vederlonel codice WordPress qui: http://codex.wordpress.org/Class_Reference/WP_Query#Parameters
I would personally do this rather.

Instead of:

'category' => '3',

Replace it with this:

'category_name' => 'my-category-slug'

Obviously find the name of your category slug and replace 'my-category-slug'.

As mentioned by @s-ha-dum it would be better to not use this method and rather use WP_Query method. You can see it in the WordPress Codex here: http://codex.wordpress.org/Class_Reference/WP_Query#Parameters

Ottienii primi cinquepost con una categoria specifica

 <?php

            'post_status' => 'publish',
            'posts_per_page' => 5,
        ));
        ?>

        <?php if ($the_query->have_posts()) : ?>
            <?php while ($the_query->have_posts()) : $the_query->the_post(); ?>
                <?php the_category(); ?>
                <?php the_title(); ?>

Aggiungi questo codiceneltuofile difunzioni:

 function wpsites_display_one_category( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
    $query->set( 'cat', '3' );
    }
}
add_action( 'pre_get_posts', 'wpsites_display_one_category' );

Modificail tag condizionale is_home ()in modo che corrisponda allapagina dellenotizie o al loop dellapagina deipost,senecessario.Qualunque cosaimpostiin Impostazioni> Lettura.

Add this code in your functions file:

function wpsites_display_one_category( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
    $query->set( 'cat', '3' );
    }
}
add_action( 'pre_get_posts', 'wpsites_display_one_category' );

Change the is_home() conditional tag to match your news page or posts page loop if needed. Whatever you set in Settings > Reading.

Dovresti cambiare

 'category'         => '3',

anel codice.

 'cat' => '3',

You should change

'category'         => '3',

to in your code.

'cat' => '3',

L'argomentonon è category,è cat. Latua querynon riesceperché stai utilizzando un argomento chenonesiste.

 $args = array(
  'post_type' => 'post' ,
  'orderby' => 'date' ,
  'order' => 'DESC' ,
  'posts_per_page' => 6,
  'cat'         => '3',
  'paged' => get_query_var('paged'),
  'post_parent' => $parent
); 
$q = new WP_Query($args);
if ( $q->have_posts() ) { 
  while ( $q->have_posts() ) {
    $q->the_post();
    // your loop
  }
}

Notare che ho convertitoiltuo query_posts()in unnuovo oggetto WP_Query. Non utilizzaremai query_posts(). Ancheil Codex lo afferma.

Nota: questafunzionenon èpensataperessere utilizzata daplugin otemi. Come spiegatopiù avanti,ci sono opzionimigliorie piùperformanti damodificare la domandaprincipale. query_posts () è unmodoeccessivamente semplicisticoe problematico permodificare la queryprincipale di unapagina sostituendola con unanuovaistanza di la query. Èinefficiente (eseguenuovamente le query SQL)e lofarà atitolo definitivo fallirein alcune circostanze (soprattutto quando sitratta dipost impaginazione). Qualsiasi codice WPmoderno dovrebbe utilizzaremetodipiù affidabili,come facendo uso dell'hookpre_get_posts,per questo scopo.

http://codex.wordpress.org/Function_Reference/query_posts

Nota anche che ho rimossoi tag di aperturae chiusura PHPnonnecessarie hoformattatoil codiceper unamigliore leggibilità. Quella sintassi della struttura di controllo alternativa è unaformulaperilfallimento,nellamiaesperienza.

The argument isn't category, it is cat. Your query fails because you are using an argument that doesn't exist.

$args = array(
  'post_type' => 'post' ,
  'orderby' => 'date' ,
  'order' => 'DESC' ,
  'posts_per_page' => 6,
  'cat'         => '3',
  'paged' => get_query_var('paged'),
  'post_parent' => $parent
); 
$q = new WP_Query($args);
if ( $q->have_posts() ) { 
  while ( $q->have_posts() ) {
    $q->the_post();
    // your loop
  }
}

Notice that I have converted your query_posts() into a new WP_Query object. Do not use query_posts(), ever. Even the Codex states so.

Note: This function isn't meant to be used by plugins or themes. As explained later, there are better, more performant options to alter the main query. query_posts() is overly simplistic and problematic way to modify main query of a page by replacing it with new instance of the query. It is inefficient (re-runs SQL queries) and will outright fail in some circumstances (especially often when dealing with posts pagination). Any modern WP code should use more reliable methods, like making use of pre_get_posts hook, for this purpose.

http://codex.wordpress.org/Function_Reference/query_posts

Also note that I removed unnecessary PHP opening and closing tags and formatted the code for better readability. That alternative control structure syntax is a formula for failure, in my experience.
