I am hitting a wall here, although it sounds pretty simple: I want to return a hierarchical list of custom post type taxonomy terms. What I get is the first level of terms and nested uls. But the sub terms are not showing. Any ideas?
Here's the code:
function return_terms_index() {
$taxonomies = array(
'taxonomy_name',
);
$args = array(
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => false,
'fields' => 'all',
'parent' => 0,
'hierarchical' => true,
'child_of' => 0,
'pad_counts' => false,
'cache_domain' => 'core'
);
$terms = get_terms($taxonomies, $args);
$return .= '<ul>';
foreach ( $terms as $term ) {
// return terms (working)
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$term->term_id,
$term->name,
$term->description
);
$subterms = get_terms( array(
'parent' => $term->term_id,
'hide_empty' => false
));
$return .= '<ul>';
foreach ( $subterms as $subterm ) {
//return sub terms (not working :( )
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$subterm->term_id,
$subterm->name,
$subterm->description
);
$return .= '</li>'; //end subterms li
}
$return .= '</ul>'; //end subterms ul
$return .= '</li>'; //end terms li
} //end foreach term
$return .= '</ul>';
return $return;
}
Thanks!
Edit: here's the output.
<ul>
<li id="category-176">
1. <span class="post-count">0</span><span class="cat-description" style="display: none;">Description</span>
<ul id="subTerm-176" style="display: block;"></ul>
</li>
<li id="category-49">
2. <span class="post-count">0</span><span class="cat-description" style="display: none;">Langtitel/Beschreibung</span>
<ul id="subTerm-49" style="display: none;"></ul>
</li>
</ul>
Edit: taxonomies are returned in hierarchical list now, YAY!
But I want to query and display posts of third level taxonomy terms as well and this bit of code doesn't do the trick.
$post_query = new WP_Query($taxonomies, array(
'term' => $subsubterm->term_id
)); ?>
<?php if ( $post_query->have_posts() ) :
$return .= '<ul>';
while ( $post_query->have_posts() ) : $post_query->the_post();
$return .= '<li><a class="link" href="' . get_permalink() . '">' . get_the_title() . '</a></li>' . "\n";
endwhile;
$return .= '</ul>';
wp_reset_postdata();
else:
endif;
It has to be dynamic, so I can't specify a term by name/slug. But is this even possible?
'term' => $subsubterm->term_id
Thanks again.
You have missed to pass $taxonomies in
$subterms = get_terms($taxonomies, array(
'parent' => $term->term_id,
'hide_empty' => false
));
Try following code
function return_terms_index() {
$taxonomies = array(
'taxonomy_name',
);
$args = array(
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => false,
'fields' => 'all',
'parent' => 0,
'hierarchical' => true,
'child_of' => 0,
'pad_counts' => false,
'cache_domain' => 'core'
);
$terms = get_terms($taxonomies, $args);
$return .= '<ul>';
foreach ( $terms as $term ) {
// return terms (working)
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$term->term_id,
$term->name,
$term->description
);
$subterms = get_terms($taxonomies, array(
'parent' => $term->term_id,
'hide_empty' => false
));
$return .= '<ul>';
foreach ( $subterms as $subterm ) {
//return sub terms (not working :( )
$return .= sprintf(
'<li id="category-%1$s" class="toggle">%2$s <span class="cat-description">%3$s</span>',
$subterm->term_id,
$subterm->name,
$subterm->description
);
$return .= '</li>'; //end subterms li
}
$return .= '</ul>'; //end subterms ul
$return .= '</li>'; //end terms li
} //end foreach term
$return .= '</ul>';
return $return;
}
Just use the wp_list_categories() function :
https://developer.wordpress.org/reference/functions/wp_list_categories/
$tax_args = array(
'taxonomy' => 'my_custom_taxonomy',
'orderby' => 'name',
'show_count' => 1,
'hierarchical' => 1,
'title_li' => 'My list title'
);
wp_list_categories($tax_args);

I have a functional shortcode that outputs all products. Problem is, I need this to only "find" simple products.
add_shortcode('product_list', 'simple_product_list');
function simple_list_shortcode() {
$query = new WP_Query( array(
'posts_per_page' => -1,
'post_type' => 'product',
'post_status' => 'publish',
'hide_empty' => 0,
'orderby' => 'title',
'post_id' => 'id'));
$output = '<ul style="list-style-type:none">';
while ( $query->have_posts() ) : $query->the_post();
$product = wc_get_product($query->post->ID);
$price = $product->get_regular_price();
$output .= '<li>' . $query->post->post_title . ' costs '.wc_price($price) . ', <a class="atc" href="'. $product->add_to_cart_url() .'">order now</a>.</li>';
endwhile;
wp_reset_postdata();
return $output.'</ul>';
}
Since it is already using 'post_type' => 'product', I cannot add another with simple.
I tried using a if statement for ->is_type('simple'), but doing so turned the page white and nothing is displayed.
Your shortcode callback function and your actual function name is different.
You can get product type using $product->get_type() function.
UPDATE 1: Using WP_Query().
add_shortcode('product_list', 'simple_list_shortcode');
function simple_list_shortcode()
{
ob_start();
$query = new WP_Query(array(
'posts_per_page' => -1,
'post_type' => 'product',
'post_status' => 'publish',
'hide_empty' => 0,
'orderby' => 'title',
'post_id' => 'id'
));
$output = '<ul style="list-style-type:none">';
while ($query->have_posts()) : $query->the_post();
$product = wc_get_product($query->post->ID);
if($product->get_type() == 'simple'){
$price = $product->get_regular_price();
$output .= '<li>' . $query->post->post_title . ' costs ' . wc_price($price) . ', <a class="atc" href="' . $product->add_to_cart_url() . '">order now</a>.</li>';
}
endwhile;
wp_reset_postdata();
echo $output . '</ul>';
$contents = ob_get_clean();
return $contents;
}
UPDATE 2: you can also use wc_get_products() function to get products with arguments.
add_shortcode('product_list', 'simple_product_list');
function simple_product_list()
{
$arg = array(
'type' => 'simple',
'orderby' => 'date',
'order' => 'DESC',
) ;
$products = wc_get_products($arg);
ob_start();
$output = '<ul style="list-style-type:none">';
foreach( $products as $product){
$price = $product->get_regular_price();
$output .= '<li>' . $product->get_name() . ' costs ' . wc_price($price) . ', <a class="atc" href="' . $product->add_to_cart_url() . '">order now</a>.</li>';
}
echo $output . '</ul>';
$contents = ob_get_clean();
return $contents;
}
I use this code to display the main categories of my woocommerce store Now, I want to display the subcategories of that category using the category name
my code
<?php
function woocommerce_subcats_from_parentcat_by_NAME($parent_cat_NAME) {
$IDbyNAME = get_term_by('name', $parent_cat_NAME, 'product_cat');
$product_cat_ID = $IDbyNAME->term_id;
$args = array(
'hierarchical' => 1,
'show_option_none' => '',
'hide_empty' => 0,
'parent' => $product_cat_ID,
'taxonomy' => 'product_cat'
);
$subcats = get_categories($args);
foreach ($subcats as $sc) {
$link = get_term_link( $sc->slug, $sc->taxonomy );
echo '<div class="col-md-4" title="'.$sc->name.'">
'.$sc->name.'</div>
<ul class="section-header-ul">
<li><i class="fas fa-caret-left"></i>لبتاب </li>
</ul>
</div>';
}
}
?>
<?php woocommerce_subcats_from_parentcat_by_NAME("electronic_components"); ?>
<?php
$taxonomyName = "com_category";
$parent_terms = get_terms($taxonomyName, array('parent' => 0, 'orderby' => 'slug', 'hide_empty' => false));
foreach ($parent_terms as $pterm) {
$terms = get_terms($taxonomyName, array('parent' => $pterm->term_id, 'orderby' => 'slug', 'hide_empty' => false));
foreach ($terms as $term) {
echo '<div class="single_cat col-md-3">';
echo '<h3>'.$pterm->name.'</h3>';
echo "<ul>";
echo '<li>' . $term->name . '</li>';
echo "</ul>";
echo '</div>';
}
}

I would like to display categories (from taxonomy-product_category) in archive-product.php.
Get categories:
Fruit
Herbs
Salad
Vegetables
See screenshot what I mean:
When I added coding in archive-product.php:
<?php
$args = array(
'post_type' => 'product',
'taxonomy' => 'product_category',
'hierarchical' => 1,
'nopaging' => false,
'posts_per_page' => '2',
'posts_per_archive_page' => '10',
'ignore_sticky_posts' => true,
'order' => 'rand',
);
echo '<div class="container">';
echo '<div class="row">';
// The Query
$query = new WP_Query( $args );
// The Loop
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
echo '<div class="col-lg-4">';
echo '<a href="'.get_the_permalink().'">';
if ( has_post_thumbnail() ) {
the_post_thumbnail(array(486,226));
}
the_title();
the_content();
echo '</a>';
echo '</div>';
}
} else {
// no posts found
echo wpautop( 'Sorry, no posts were found' );
}
echo '</div>';
echo '</div>';
// Previous/next post navigation.
previous_post_link( '%link', 'Prev post in category', true
);
next_post_link( '%link', 'Next post in category', true );
// Restore original Post Data
wp_reset_postdata();
?>
But not display categories (Fruit, Herbs, Salad, Vegetables)
Would anyone know about this?
Thanks,
Shaun.
Please try below code:
$args = array(
'taxonomy'=> 'product_category',
'order' => 'DESC',
);
$categories = get_categories($args);
print_r($categories);
You can get the list of all product categories using Below code
$orderby = 'name';
$order = 'asc';
$hide_empty = false ;
$cat_args = array(
'orderby' => $orderby,
'order' => $order,
'hide_empty' => $hide_empty,
);
$product_categories = get_terms( 'product_cat', $cat_args );
if( !empty($product_categories) ){
echo '
<ul>';
foreach ($product_categories as $key => $category) {
echo '
<li>';
echo '<a href="'.get_term_link($category).'" >';
echo $category->name;
echo '</a>';
echo '</li>';
}
echo '</ul>
';
}
I am trying to get the parent category link - this is my code but it doesnt seem to be working.
<?php
$taxonomyName = "equipment_categories";
$parent_terms = get_terms($taxonomyName, array('parent' => 0, 'orderby' => 'slug', 'hide_empty' => false));
echo '<div class="subcats"><a class="subcatseach" href="' . $cat = get_the_category(); $cat = $cat[0]; echo get_category_link($cat->cat_ID) . '">All Equipment</a>';
foreach ($parent_terms as $pterm) {
$terms = get_terms($taxonomyName, array('parent' => $pterm->term_id, 'orderby' => 'slug', 'hide_empty' => false));
foreach ($terms as $term) {
echo '<a class="subcatseach" href="' . get_term_link( $term->name, $taxonomyName ) . '">' . $term->name . '</a>';
}
}
echo '</div>';
?>
Any suggestions?
try using 'child_of' => $pterm->term_id instead of 'parent' => $pterm->term_id in line 6
For example i have a post in category: cat1,cat2,cat3 and i want to exclude cat1 and show only one from cat2 or cat3.
<?php
$categories = get_the_category();
$separator = ' ';
$output = '';
if($categories){
foreach($categories as $category) {
if($category->name !== 'Cat1'){
$output .= $category->cat_name;}
}
echo trim($output, $separator);
}
?>
I have tried this loop but it only works for excluding "Cat1" i also want to show one category from get_the_category(); ?
Can someone help me?
exclude category by using "exclude" argument with comma separated value category id in wordpress
<?php
$cat_args = array(
'type' => 'post',
'parent' => 0,
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => 0,
'hierarchical' => true,
'exclude' => '1,2,3',
'include' => '',
'number' => '',
'taxonomy' => 'category',
'pad_counts' => true
);
$categories = get_categories( $cat_args );
if(count($categories )>0)
{
$separator = ' ';
$output = '';
foreach ( $categories as $category ) {
$output .= $category->cat_name;
echo trim($output, $separator);
}
}
?>
Something like this
foreach($categories as $category) {
if($category->name !== 'Cat1'){
$output = $category->cat_name;
if($output != '') break; //end foreach when we have value
}
