Devomostraretutte le sottocategorie utilizzando

 $product_category = wp_get_post_terms( $post->ID, 'product_cat' );

attualmenteio uso:

 <?php 

global $post;

$terms = get_the_terms( $post->ID, 'product_cat', 'hide_empty=0'  );
foreach ( $terms as $term ){
    $category_id = $term->term_id;
    $category_name = $term->name;
    $category_slug = $term->slug;

    echo '<li><a href="'. get_term_link($term->slug, 'product_cat') .'">'.$category_name.'</a></li>';
}   

?>

Vabene mamostra solo la categoriaprincipalee solo una sottocategoria ...

Come risolverlo?

I need to show all subcategories using

$product_category = wp_get_post_terms( $post->ID, 'product_cat' );

actually I use:

<?php 

global $post;

$terms = get_the_terms( $post->ID, 'product_cat', 'hide_empty=0'  );
foreach ( $terms as $term ){
    $category_id = $term->term_id;
    $category_name = $term->name;
    $category_slug = $term->slug;

    echo '<li><a href="'. get_term_link($term->slug, 'product_cat') .'">'.$category_name.'</a></li>';
}   

?>

It's ok but it shows only the parent category and only one subcategory...

How to fix that?

Eccoil codice che hafunzionatoperme in unmodello dipagina (ilmio IDgenitoreera 7):

 <?php $wcatTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'parent' => 7, )); 
        foreach($wcatTerms as $wcatTerm) : 
        $wthumbnail_id = get_woocommerce_term_meta( $wcatTerm->term_id, 'thumbnail_id', true );
        $wimage = wp_get_attachment_url( $wthumbnail_id );
    ?>
    <div><a href="<?php echo get_term_link( $wcatTerm->slug, $wcatTerm->taxonomy ); ?>">
    <?php if($wimage!=""):?><img src="<?php echo $wimage?>" class="aligncenter"><?php endif;?></a>
    <h3 class="text-center"><a href="<?php echo get_term_link( $wcatTerm->slug, $wcatTerm->taxonomy ); ?>"><?php echo $wcatTerm->name; ?></a></h3>
    </div>
    <?php endforeach; ?>

Here is the code that worked for me in a page template (my parent id was 7):

<?php $wcatTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'parent' => 7, )); 
        foreach($wcatTerms as $wcatTerm) : 
        $wthumbnail_id = get_woocommerce_term_meta( $wcatTerm->term_id, 'thumbnail_id', true );
        $wimage = wp_get_attachment_url( $wthumbnail_id );
    ?>
    <div><a href="<?php echo get_term_link( $wcatTerm->slug, $wcatTerm->taxonomy ); ?>">
    <?php if($wimage!=""):?><img src="<?php echo $wimage?>" class="aligncenter"><?php endif;?></a>
    <h3 class="text-center"><a href="<?php echo get_term_link( $wcatTerm->slug, $wcatTerm->taxonomy ); ?>"><?php echo $wcatTerm->name; ?></a></h3>
    </div>
    <?php endforeach; ?>

Unaformapiù semplice della risposta di @mikes senza l'opzioneimmagine -può sostituire le righe 6-10 con: nome;?>

A simpler form of @mikes's answer without the image option - can replace lines 6-10 with: name; ?>

Prova qualcosa di simile:

per ID

 function woocommerce_subcats_from_parentcat_by_ID($parent_cat_ID) {
    $args = array(
       'hierarchical' => 1,
       'show_option_none' => '',
       'hide_empty' => 0,
       'parent' => $parent_cat_ID,
       'taxonomy' => 'product_cat'
    );
  $subcats = get_categories($args);
    echo '<ul class="wooc_sclist">';
      foreach ($subcats as $sc) {
        $link = get_term_link( $sc->slug, $sc->taxonomy );
          echo '<li><a href="'. $link .'">'.$sc->name.'</a></li>';
      }
    echo '</ul>';
}

di NAME

 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);
    echo '<ul class="wooc_sclist">';
      foreach ($subcats as $sc) {
        $link = get_term_link( $sc->slug, $sc->taxonomy );
          echo '<li><a href="'. $link .'">'.$sc->name.'</a></li>';
      }
    echo '</ul>';
}

Try something like this:

by ID

function woocommerce_subcats_from_parentcat_by_ID($parent_cat_ID) {
    $args = array(
       'hierarchical' => 1,
       'show_option_none' => '',
       'hide_empty' => 0,
       'parent' => $parent_cat_ID,
       'taxonomy' => 'product_cat'
    );
  $subcats = get_categories($args);
    echo '<ul class="wooc_sclist">';
      foreach ($subcats as $sc) {
        $link = get_term_link( $sc->slug, $sc->taxonomy );
          echo '<li><a href="'. $link .'">'.$sc->name.'</a></li>';
      }
    echo '</ul>';
}

by NAME

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,

  $subcats = get_categories($args);

Completed the code, tested it, see comments

Grazie,manon so comeinserire quel codicenelmio,comunque hotrovato questo codice: [http://wordpress.stackexchange.com/questions/73795/how-to-split-the-categories-of-subcategories-with-thumbnails] mamostratutte le categorie,hobisogno di una sola categoria selezionata con le sue sottocategorie

Thanks, but I don't know how to put that code into mine, anyway I found this code : [http://wordpress.stackexchange.com/questions/73795/how-to-split-the-categories-of-subcategories-with-thumbnails] but it shows All categories, I need just One category selected with its subcategories

Ho dato una rapida occhiata al codice dalle domande che hai collegato.Quello che stai cercando difare èfare solo ciò che è associato a `$ sub_cats=get_categories ($ args2)`e laparte `$ args2=array (...)`,ma detto ciò,ciò che ho suggerito èpraticamente lo stesso.Quindinon sono davvero sicuro delmotivoper cuinonfunzionaperte.

I took a quick look at the code from the questions you linked. What you are lloking to do is only do whats associated to `$sub_cats = get_categories( $args2 )` and the `$args2 = array( ... )` part, but that said, what i suggested is pretty much the same. So I'm not really sure why it isn't working for you.

se rimuovo `function woocommerce_subcats_from_parentcat ($parent_cat) {` funziona,mamostra solo le categorieprincipali,non le sottocategorie,se copioe incolloil codice così com'è,viene visualizzato vuoto,nessuno.

if I remove `function woocommerce_subcats_from_parentcat($parent_cat) {` it works, but shows only main categories, not subcategories, if I copy and paste your code as it is, it shows blank, none.

siprobabilmente è la soluzionemigliore,ma comeposso chiamare queste duefunzioninellamiapagina?

yes probably is the best solution, but how can i call these two functions in my page?

comunqueilproblema rimane ancora: woocommerce_subcats_from_parentcat_by_ID ($parent_cat_ID)mostra solo le sottocategoriee woocommerce_subcats_from_parentcat_by_NAME ($parent_cat_NAME)mostra solo TUTTE le categorieprincipali senza sottotitoli.

anyway, the problem still remains: woocommerce_subcats_from_parentcat_by_ID($parent_cat_ID) displays only sub categories, and woocommerce_subcats_from_parentcat_by_NAME($parent_cat_NAME) displays only ALL main categories with no sub.

Hobisogno di MAIN-> sube una volta cliccato su sub dovrebbeessere lo stesso delgenitore 'MAIN-> sub'.Hobisogno che questotipo dimenunon cambi se clicco su MAIN o su un sub

I need MAIN->sub and once i click on sub it should be the same as parent 'MAIN->sub'. I need that this kind of menu doesn't change if I clik on MAIN or a sub

Prima ditutto,entrambe lefunzionifunzionanoperfettamenteperme,forsene stai usando unain modo sbagliato.In secondo luogo,dovrestiesserein grado di ottenereil comportamento desiderato con leinformazioni quie sulla domanda collegata sopra.Inbocca al lupo!

First of all, both functions are working perfectly fine for me, you are maybe using one of them wrong. Secondly, you should be able to achieve the wanted behaviour with the information here and on the question linked above. Good luck!
