Child page excerpt

Question

I have a parent page with some child pages inside. What I'm looking to do is display every child page excerpt and some other information inside its own cell on the parent page. Does anyone know how this can be achieved ?

<div class="parent page">

    <?php  $args = array(
          'parent' => $post->ID,
          'post_type' => 'page',
          'post_status' => 'publish'
      ); 
      $pages = get_pages($args);  ?>
      <div class="childcells"> 
      <?php foreach( $pages as $page ) { ?>
       <div class="childcell">
          <div class="thumbnail"><?php echo get_the_post_thumbnail($page->ID, 'small-thumb'); ?></div>
          <div class="myclasstitle"><?php echo $page->post_title; ?></div>
          <span class="desc"><?php echo get_post_meta($page->ID, 'desc', true); ?></span>
      <a href="<?php echo  get_permalink($page->ID); ?>" rel="bookmark" title="<?php echo $page->post_title; ?>">
            Read more
          </a>

      </div>

?>

Answer 1

get_the_excerpt() won't work in your code if you add content to the main WYSIWYG editor instead of the excerpt field.

Check how get_the_excerpt() work and try to find out filter hook with get_the_excerpt hook name.

Please try the following code, hope you'll get the expected result.

<div class="parent page">
    <?php
    global $post;
    $args = array(
        'parent'      => $post->ID,
        'post_type'   => 'page',
        'post_status' => 'publish'
    ); 
    $children = get_pages( $args );

    if ( ! empty( $children ) ) :
        ?>
        <div class="childcells"> 
            <?php
            foreach ( $children as $post ) : setup_postdata( $post );
                ?>
                <div class="childcell">
                    <?php if ( has_post_thumbnail() ) : ?>
                        <div class="thumbnail"><?php the_post_thumbnail( 'small-thumb' ); ?></div>
                    <?php endif; ?>
                    <div class="myclasstitle"><?php the_title(); ?></div>
                    <span class="desc"><?php echo get_post_meta( get_the_ID(), 'desc', true ); ?></span>
                    <div class="excerpt"><?php the_excerpt(); ?></div>
                    <a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php the_title_attribute(); ?>">Read more</a>
                </div>
                <?php
            endforeach;
            wp_reset_postdata();
            ?>
        </div>
    <?php endif; ?>
</div>
