mikeboy3Greetings, I have been working on a site that requires a very complex category display, it's a product catalog and it is organized in categories and sub-categories.
The category pages have to display all posts organized by sub-category, something like:
Main Category
Sub-Cat1
Post1
Post2
Sub-Cat2
Post3
Post4
So far, thanks to help from guys at this forum, we have managed to make that work by using the following code:
<?php
//get terms (e.g. categories or post tags), then display all posts in each retrieved term
$taxonomy = 'category';// e.g. post_tag, category
$current_cat = get_query_var('cat');
$param_type = 'category__in'; // e.g. tag__in, category__in
$term_args=array(
'orderby' => 'name',
'order' => 'ASC',
'child_of' => get_query_var('cat')
);
$terms = get_terms($taxonomy,$term_args);
if ($terms) {
foreach( $terms as $term ) {
$args=array(
"$param_type" => array($term->term_id),
'post_type' => 'post',
'post_status' => 'publish',
'showposts' => -1,
'caller_get_posts'=> 1,
'orderby'=> 'title',
'order'=> 'ASC',
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
echo '<div class="gs12col" id="cat_title" >
<h4>' . $term->name. '</h4>
</div> ';
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<div class="gs480" id="postclass">
<div class="gs2col" id="thumbnail">
<a href="<?php the_permalink() ?>"><?php the_post_thumbnail( array(140,140) ); ?></a>
</div>
<div class="gs4col" id="postcontent">
<a href="<?php the_permalink() ?>"><h5><?php the_title(); ?></h5></a>
<?php the_excerpt(); ?>
</div>
</div>
<?php
endwhile;
}
}
}
wp_reset_query(); // Restore global post data stomped by the_post().
?>Now, I need to display an image thumbnail and I want to use this code:
<?php
foreach((get_the_category()) as $category) {
echo '<img src="http://example.com/images/' . $category->cat_ID . '.jpg" alt="' . $category->cat_name . '" />';
}
?>Found here at the CODEX
However, this does not work properly, since it does not identify the correct cat_ID, it uses one of the sub-category's ID instead of the main category.
I think the solution is to combine both codes so that as it identifies the main category to get all sub-cats, it can also define the image's cat_ID as the main category. I don't know how to do this, I've been trying but no luck.
Any ideas?
Thanks in advance! I know it was a long post, thanks for taking the time to help!
