display child posts based on category terms

3 Views

I have a custom post type named city guide . The child post articles are displayed within the parent page.Child posts has custom category named as newyork and paris. 

<div class="container">
<?php while( have_posts() ): the_post();  ?>
<div class="row main-content-wrap">
  <div class="col-md-12 long-post-sections-wrapper">
<?php while( $city_guide->have_posts() ): $city_guide->the_post(); 
$terms = get_the_terms( $post->ID , 'city-guide-cities-category' );
 // Loop over each item since it's an array
 if ( $terms != null ){
 foreach( $terms as $term ) {
 // Print the name method from $term which is an OBJECT
 print $term->name ;

} }
 ?> 

<div <?php post_class('city-guide-row row' . classes_related($wp_query->current_post) ); ?>>
    <div class="col-sm-8">
        <h3 id="<?php echo esc_attr( get_post()->post_name ); ?>"><?php the_title(); ?></h3>

        <?php the_post_thumbnail(); ?>
        <div class="img-caption"><?php echo get_post(get_post_thumbnail_id())->post_excerpt; ?></div>
        <?php the_content(); ?>
    </div>

    <div class="col-sm-4 map-container">

        <!-- google map -->
        <div class="map-wrapper">
            <div class="mobile-map-overlay" onClick="style.pointerEvents='none'"></div>
            <iframe frameborder="0" scrolling="no" marginheight="0" marginwidth="0"width="100%" height="260" src="https://maps.google.com/maps?hl=en&q=<?php echo get_field('address',get_the_ID()); ?>&ie=UTF8&t=roadmap&z=6&iwloc=B&output=embed&z=16"></iframe>
        </div>

        <h5>Address</h5>
        <?php echo get_field('address'); ?><br/>
        <?php echo get_field('address_2'); ?>

        <h5>Contact</h5>
        <?php if(get_field('contact_number')): 
            echo '<a href="tel:' . get_field('contact_number') . '">' . get_field('contact_number') . '</a>';
        endif; ?><br/>
        <?php if(get_field('website')): 
            echo '<a href="' . get_field('website') . '" target="_blank">' . get_field('website') . '</a>';
        endif; ?><br/>
        <?php if(get_field('email')): 
            echo '<a href="mailto:' . get_field('email') . '">' . get_field('email') . '</a>';
        endif; ?>

    </div>
    <div class="clearfix"></div>
<hr class="city-row-separator"/>
<?php endwhile; ?>
</div>
</div>
<?php endwhile; ?>

I have printed print $term->name ; inside while so each child article is showing its own categories.

  1. Let me guide you through simple code as per your current code

    though It is not the standard solution , but can complete the
    requirement

    Run the loop and collect the posts in NewYork and Paris in separate array as $NY_array and $PA_array
    and their Posts Ids also in separate arrays $NY_Posts and $PA_Posts

    Edit starts

     <?php 
while( have_posts() ): the_post();
        $terms = get_the_terms( $post->ID , 'city-guide-cities-category' );
         // Loop over each item since it's an array
        if ( $terms != null ){
            foreach( $terms as $term ) {
                if ( $term->name == 'newyork'){
                    $NY_array[] = array('term_id'=> $term->term_taxonomy_id, 'count' => $term->count);
                    $NY_Posts[] = $post->ID;
                } 
                elseif ( $term->name == 'paris'){
                    $PA_array[] = array('term_id'=> $term->term_taxonomy_id, 'count' => $term->count);
                    $PA_Posts[] = $post->ID;
                }
            }
        }
    endwhile; ?>

    Edit Ends

    Now run the 2 separate loops first for Newyork and then for Paris

    <?php 
foreach ($NY_array as $key => $value) {
    $args = array(
    'post__in' => $NY_Posts,
    );

    $posts = get_posts($args);

    foreach ($posts as $p) :
        //do the code here 
        //below code replaced by 
            //$p->post_title;
            //$p->post_excerpt
            //get_field('address',$p->ID); 
            //get_field('address_2',$p->ID); 
            //get_field('contact_number',$p->ID); and so on 
            // try to print print_r($p) if you need to print some data from Post like content, title, featured image etc
    endforeach;
}
?>

    Similarly for the PA_array

    <?php foreach ($PA_array as $key => $value) {
    $args = array(
    'post__in' => $PA_Posts,
    );

    $posts = get_posts($args);

    foreach ($posts as $p) :
        //do the code here 
        //below code replaced by 
            //$p->post_title;
            //$p->post_excerpt
            //get_field('address',$p->ID); 
            //get_field('address_2',$p->ID); 
            //get_field('contact_number',$p->ID); and so on 
            // try to print print_r($p) if you need to print some data from Post like content, title, featured image etc
    endforeach;
}?>
