I`m writing a wordpress theme. I need to display all parents of the current item that belongs to some taxonomy. The first thing I need to do is to get the taxonomy of the item that is displayed. Here what I tried to do:
$id = get_the_ID();
$taxonomy = get_term_by('id', $id)['taxonomy'];
echo 'Current taxonomy is ' . $taxonomy;
$terms = get_the_terms( $id, $taxonomy);
for($i = count( $terms ) - 1; $i >= 0; $i--){
echo '>' . $terms[$i]->name . '';
}
The first problem I`ve faced is $taxonomy = "". Please help me.
$id = get_the_ID();
$taxonomy = get_term_by('id', $id)['taxonomy'];
Tou are getting empty $taxonomy because you are trying to get term details using the id of a post and Not the term id. To get the terms associated with the post you have to do this:
$terms = wp_get_post_terms( $post_id, $taxonomy, $args );
you can get your terms by wp_get_post_terms for more informationclick here

Im trying to display the current post category name for a custom post types' taxonomy, but exclude one of the categories. I see different solutions in StackOverflow, but I can't seem to get any of them to work for me. Below is the code I am using, which works great, but I don't know how to exclude one ID using it.
<?php $terms = get_the_terms( $post->ID , 'press_category' );
foreach ( $terms as $term ) {
$term_link = get_term_link( $term, 'press_category' );
if( is_wp_error( $term_link ) )
continue;
echo $term->name ;
}
?>
Try this
<?php $terms = get_the_terms($post->ID, 'press_category');
foreach ($terms as $term)
{
$term_link = get_term_link($term, 'press_category');
if (is_wp_error($term_link)) continue;
if ($term->term_id != 222)
{
echo $term->name;
}
}
?>
Change 222 in this line to your taxonomy id for exclude
$term->term_id != 222
I need to list the taxonomies that apply to this post. If the taxonomy only one then this code works well:
global $post;
$terms = wp_get_post_terms($post->ID, 'gintype');
if($terms){
$output = array();
foreach($terms as $term){
$outputnk[] = get_term_link( $term->slug, 'gintype');
$outputme[] = $term->name;
}
}
But if a post has several taxonomy items this code does not work.
This code is working for me:
global $post;
$terms = wp_get_post_terms($post->ID, 'gintype');
foreach($terms as $term){
$term_link = get_term_link( $term );
echo '<div>' . $term->name . '';
}
I'm trying to display the taxonomy term of a custom post type (like using <?php the_category( ' ' ); ?> in regular posts). The code below works but need to specify the taxonomy name, is there a way to use only the Post ID?
<?php
$terms = get_the_terms( $post->ID , 'taxonomy_name' );
foreach ( $terms as $term ) {
echo $term->name;
}
?>
Thanks in advance!
<?php print the_terms( $post->ID, 'taxonomy_name' , ' ' ); ?>
You cannot get the custom taxonomy terms without taxonomy name but the above code its shorter for you.
I found a way to do it. Using "get_post_taxonomies" and selecting the array witch cat[1]
<?php
$cat = get_post_taxonomies($post);
$terms = get_the_terms( $post->ID , $cat[1] );
// Loop
if ( $terms != null ){
foreach( $terms as $term ) {
$term_link = get_term_link( $term, $cat[1] );
// Print the name and URL
echo '' . $term->name . '';
unset($term); } }
?>
Try this.,
$term_list = wp_get_post_terms($post->ID, 'my_taxonomy', array("fields" => "names"));
print_r($term_list);
You must use the taxonomy without taxonomy can not get term details.
Thanks you!
I'm using WooCommerce with WordPress to build a store of Antique Photos.
I'm using the WooCommerce product attributes feature to store information about an item photographer.
See here for an example, photographer attribute is pulled out in the box on the left http://bit.ly/1Dp999O
The code that pulls out the attribute looks like this:
if($attribute['is_taxonomy']) {
$values=wc_get_product_terms($product->id, $attribute['name'], array('fields' => 'names'));
echo apply_filters('woocommerce_attribute', wpautop(wptexturize(implode(', ', $values))), $attribute, $values);
}
$values looks like this:
Array ( [0] => Photographer 1 )
The problem is, how do I get to the permalink for the Photographer which is automatically generated by WordPress and WooCommerce:
http://bit.ly/1JtwBna
I can't find any documentation for this within WooCommerce, and this seems to be a taxonomy within a taxonomy which goes a bit further than stabdard WordPress, but I'm assuming this is a fairly standard requirement. Any pointers appreciated.
Once you have the attribute term (in this case the photographer's name) you can use get_term_link() to get the URL. Because the $product id isn't passed to the woocommerce_attribute folder, I couldn't filter that, but instead create an override of the product-attributes.php template. And modified the relevant section to be the following:
if ( $attribute['is_taxonomy'] ) {
$terms = wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'all' ) );
$html = '';
$counter = 1;
$total = count( $terms );
foreach( $terms as $term ){
$html .= sprintf( '%s',
esc_url( get_term_link( $term ) ),
esc_attr( $term->name ),
wptexturize( $term->name )
);
if( $counter < $total ){
$html .= ', ';
}
$counter++;
}
echo wpautop( $html );
}
For some reason, the URL isn't a pretty permalink. It's late and I can't tell if this has to do with my configuration or what exactly, but it is a start.
This basically does what I require:
$terms = get_the_terms($product->id, $attribute['name']);
foreach ($terms as $term){
echo ''.$term->name.'';
}
But could do with a bit of refinement for sure.
I search all the web for that answer. I use wp_list_categories to make a submenu with custom taxonomy, It works well, and puts current-cat when I browse those categories.
The thing is, when I browse single posts with this menu, the highlight no more works.
For the blog part of that site, I use the following code to highlight current category on wp_list_categories():
function sgr_show_current_cat_on_single($output) {
global $post;
if( is_single() ) {
$categories = wp_get_post_categories($post->ID);
foreach( $categories as $catid ) {
$cat = get_category($catid);
if(preg_match('#cat-item-' . $cat->cat_ID . '#', $output)) {
$output = str_replace('cat-item-'.$cat->cat_ID, 'cat-item-'.$cat->cat_ID . ' current-cat', $output);
}
}
}
return $output;
}
add_filter('wp_list_categories', 'sgr_show_current_cat_on_single');
But as far as I tried, can't make it work for single posts that are ordered by custom taxonomy. :/ > I don't know how to custom it.
Is it even possible ?
You need to use get_the_terms( $id, $taxonomy ); instead of wp_get_post_categories(); for getting custom taxonomy term IDs.
You can hardcode taxonomy name into the functon or get it from the $args you passed into wp_list_categories( $args );.
Final code:
add_filter( 'wp_list_categories', 'sgr_show_current_cat_on_single', 10, 2 );
function sgr_show_current_cat_on_single( $output, $args ) {
if ( is_single() ) :
global $post;
$terms = get_the_terms( $post->ID, $args['taxonomy'] );
foreach( $terms as $term ) {
if ( preg_match( '#cat-item-' . $term ->term_id . '#', $output ) ) {
$output = str_replace('cat-item-'.$term ->term_id, 'cat-item-'.$term ->term_id . ' current-cat', $output);
}
}
endif;
return $output;
}
