Afficher la liste des sous-catégories et les messages qu'elles contiennent, dans une seule catégorie principale

La question a reçu une réponse sur un autre site ..merci! BTW,le code qui a accompli ce dontj'avaisbesoin était:

 $categories =  get_categories('child_of=31');  
foreach  ($categories as $category) {
    //Display the sub category information using $category values like $category->cat_name
    echo '<h2>'.$category->name.'</h2>';
    echo '<ul>';

    foreach (get_posts('cat='.$category->term_id) as $post) {
        setup_postdata( $post );
        echo '<li><a href="'.get_permalink($post->ID).'">'.get_the_title().'</a></li>';   
    }  
    echo '</ul>';
}
 

Question was answered on another site.. thank you! BTW, the code that accomplished what I needed was:

$categories =  get_categories('child_of=31');  
foreach  ($categories as $category) {
    //Display the sub category information using $category values like $category->cat_name
    echo '<h2>'.$category->name.'</h2>';
    echo '<ul>';

    foreach (get_posts('cat='.$category->term_id) as $post) {
        setup_postdata( $post );
        echo '<li><a href="'.get_permalink($post->ID).'">'.get_the_title().'</a></li>';   
    }  
    echo '</ul>';
}

Voici le codefinal utilisépour créer unepage depodcast àpartir de WP Posts. Au cas où quelqu'unpourraiten bénéficier.

 <?php     
    $categories =  get_categories('child_of=31');  
    foreach  ($categories as $category) {
        //Display the sub category information using $category values like $category->cat_name

        // display category image, if one exists - place image in /images/podcast_images/ dir  
        $cat_img = '';
        if(get_bloginfo("url") .'/wp-content/images/podcast_images/' . $category->slug . '.jpg' != ' ') {$cat_img = '<img class="podcast_category_image" src="'.get_bloginfo("url") .'/wp-content/images/podcast_images/' . $category->slug . '.jpg" />';} 

       echo '<h2 class="podcast_h2">'.$cat_img.$category->name.'</h2>'; 
        // start a list for the podcasts
        echo '<ul class="podcast_series">';
        foreach (get_posts('orderby=post_date&category='.$category->term_id) as $post) {
            setup_postdata( $post );
            // format date
            $my_date = mysql2date('F j\<\s\u\p\>S\<\/\s\u\p\>, Y', $post->post_date);

            // load the custom fields for this post, if they have content
            if(get_post_meta($post->ID, 'Speaker', true)){ 
                $speaker_name = '<div class="speaker"><strong>Speaker: </strong>'. get_post_meta($post->ID, "Speaker", true).'</div>';
            } else {
                $speaker_name = '';
            } 
            if(get_post_meta($post->ID, 'Scripture', true)){ 
                $scripture = '<div class="scripture"><strong>Scripture: </strong>'. get_post_meta($post->ID, "Scripture", true).'</div>';
            } else {
                $scripture = '';
            } 
            // echo out the results into a list item
            echo '<li><a href="'.get_permalink($post->ID).'">'.get_the_title($post->ID).'</a>'.  $speaker_name . $scripture.'<div class="podcast_date"> Recorded On: '. $my_date .'</div></li>';   
        }
        // close the list
        echo '</ul>';
    } ?>
 

Ce codeparcourttous les articles de la catégorie 31 (dans cetexemple)et affiche les sous-catégorieset leurs articles. J'ai d'abord créé une catégoriepour PODCASTS (quiest la cat. 31)et des sous-catégories qu'elle contient,pour les séries depodcast.

Le résultatest une liste de sous-chats dansnotre chat depodcastprincipal ..et lesmessages (podcasts)pour chacun de ces sous-chats répertoriésen dessous:

Sous cat1 podcast 1 podcast 2 podcast 3

Sous cat2 podcast 1 podcast 2 podcast 3

Merci àtouspour l'aide!

Here is the final code used to create a podcast page out of WP Posts. In case anyone could benefit from it.

<?php     
    $categories =  get_categories('child_of=31');  
    foreach  ($categories as $category) {
        //Display the sub category information using $category values like $category->cat_name

        // display category image, if one exists - place image in /images/podcast_images/ dir  
        $cat_img = '';
        if(get_bloginfo("url") .'/wp-content/images/podcast_images/' . $category->slug . '.jpg' != ' ') {$cat_img = '<img class="podcast_category_image" src="'.get_bloginfo("url") .'/wp-content/images/podcast_images/' . $category->slug . '.jpg" />';} 

       echo '<h2 class="podcast_h2">'.$cat_img.$category->name.'</h2>'; 
        // start a list for the podcasts
        echo '<ul class="podcast_series">';
        foreach (get_posts('orderby=post_date&category='.$category->term_id) as $post) {
            setup_postdata( $post );
            // format date
            $my_date = mysql2date('F j\<\s\u\p\>S\<\/\s\u\p\>, Y', $post->post_date);

            // load the custom fields for this post, if they have content
            if(get_post_meta($post->ID, 'Speaker', true)){ 
                $speaker_name = '<div class="speaker"><strong>Speaker: </strong>'. get_post_meta($post->ID, "Speaker", true).'</div>';
            } else {
                $speaker_name = '';
            } 
            if(get_post_meta($post->ID, 'Scripture', true)){ 
                $scripture = '<div class="scripture"><strong>Scripture: </strong>'. get_post_meta($post->ID, "Scripture", true).'</div>';
            } else {
                $scripture = '';
            } 
            // echo out the results into a list item
            echo '<li><a href="'.get_permalink($post->ID).'">'.get_the_title($post->ID).'</a>'.  $speaker_name . $scripture.'<div class="podcast_date"> Recorded On: '. $my_date .'</div></li>';   
        }
        // close the list
        echo '</ul>';
    } ?>

This code will loop through all posts in Category 31 (in this example) and display the sub-categories and their posts. I first created a category for PODCASTS (which is cat. 31) and sub categories within it, for podcast series.

The result is a list of subcats within our main podcast cat.. and the posts (podcasts) for each of those subcats listed below it:

Sub cat1 podcast 1 podcast 2 podcast 3

Sub cat2 podcast 1 podcast 2 podcast 3

Thanks to all for the help!
