I created two template pages: galerie.php and homepage.php.

Galerie already displays posts. So Homepage is homepage.php and posts page is galerie.php.

Now the problem is that I wanted to display a post from Category category-test into homepage.php. I used the following code to try to display the posts from category-test:

<?php $posts = get_posts('category_name=' . 'category-test'); foreach($posts as $post) { ?>
      <?php the_title(); ?>
      <p><?php the_content(); ?></p>
 <?php } ?>

But for some reason this only displays the post title. It doesn't display the body content of the post.

What is the problem with it?

  • You have to use setup_postdata( $post ); inside your foreach loop just before calling the_title(). This will make the template tags available – Pieter Goosen Nov 17 '14 at 16:30
  • How? Could you please add it into my code? – azhpo Nov 17 '14 at 16:32
  • Done. Just for interest sake, feel free to take a tour to learn how the site operates. :-) – Pieter Goosen Nov 17 '14 at 16:45
  • Thank you. I come from Stack Overflow. It's pretty much the same. I know how it works. :) – azhpo Nov 18 '14 at 7:34

The template tags (like the_content()) aren't available when using get_posts. In order to make the template tags available, you have to make use of setup_postdata( $post );

Example:

<?php 
$posts = get_posts('category_name=category-test'); 
foreach($posts as $post) { 
    setup_postdata( $post );

    the_title(); ?>
    <p><?php the_content(); ?></p>
<?php } ?>
  • Thank you. Worked just fine. :) Btw am I doing this right? I mean, I would like to know if this is the right way of doing what I want. And I would like to understand why did my code displayed the the_title() of the post but not the_content() – azhpo Nov 18 '14 at 7:27
  • Is homepage.php a static front page. If yes, then you are you doing it correctly. Remember, you can use get_posts or WP_Query for this. I tend to prefer WP_Query as the template tags are available by default, and it is easier to work with if you need paginated queries. – Pieter Goosen Nov 18 '14 at 8:06
  • Please see this post, this should answer a few questions for you – Pieter Goosen Nov 18 '14 at 8:11

I would use WP_Query with any of the category parameters as its more flexible.

You can add it directly to your template or create a template tag which you can then add in any file or custom function.

<?php

// The Query
$the_query = new WP_Query( 'cat=4' );

// The Loop
if ( $the_query->have_posts() ) {
    echo '<ul>';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
    echo '</ul>';
} else {
    // no posts found
}
/* Restore original Post Data */
wp_reset_postdata();

Why don't you use WP_Query? [Modified code, used WP_Query instead of query_posts as suggested]

<?php $arg = array(
    'category_name' =>  'category-test'
);
$newQ = QP_Query($arg);
while($newQ->have_posts()) : $newQ->the_post();?>
    <?php the_title(); ?>
    <p><?php the_content(); ?></p>
<?php endwhile;
wp_reset_query();
?>

    Never use query_posts. It is just a function prone to fail unexpectitely – Pieter Goosen Nov 17 '14 at 19:14
  • Never use query_posts as its highly inefficient. In this case, WP_Query is the best function. – Brad Dalton Nov 18 '14 at 2:20
