Ichmuss alle Unterkategorienmit

anzeigen

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

eigentlichbenutzeich:

 <?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>';
}   

?>

Esistin Ordnung,aberes werdennur die übergeordnete Kategorie undnureine Unterkategorie angezeigt ...

Wie kannich dasbeheben?

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?

Hierist der Code,derfürmichin einer Seitenvorlagefunktioniert hat (meine Eltern-ID war 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; ?>

Eineeinfachere Form der Antwort von @mikes ohne die Bildoption - kann die Zeilen 6-10ersetzen durch: name;?>

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

Versuchen Sie Folgendes:

nach 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>';
}

von 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,
       '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>';
      }

Danke,aberich weißnicht,wieich diesen Codein meineneinfügen soll,trotzdem habeich diesen Codegefunden: [http://wordpress.stackexchange.com/questions/73795/how-to-split-the-categories-of-subcategories-with-thumbnails] aberes zeigt alle Kategorien,ichbrauchenureine Kategoriemit ihren Unterkategorien ausgewählt

Ich habemir den Code anhand der von Ihnen verlinkten Fragen kurz angesehen.Was Sietunmöchten,istnur das zutun,wasmit "$ sub_cats=get_categories ($ args2)" und dem Teil "$ args2=array (...)" verbundenist,aber das,wasich vorgeschlagen habe,ist ziemlich dasselbe.Ichbin mir alsonicht sicher,warumesbei Ihnennichtfunktioniert.

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.

wennich die Funktion woocommerce_subcats_from_parentcat ($parent_cat) {`entferne Esfunktioniert,zeigt abernur Hauptkategorien,keine Unterkategorien. Wennich Ihren Code so kopiere undeinfüge,wieerist,wird leer angezeigt,keine.

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.

Ja,wahrscheinlichist diebeste Lösung,aber wie kannich diesebeiden Funktionen aufmeiner Seite aufrufen?

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

Trotzdembleibt das Problembestehen: woocommerce_subcats_from_parentcat_by_ID ($parent_cat_ID) zeigtnur Unterkategorien an,und woocommerce_subcats_from_parentcat_by_NAME ($parent_cat_NAME) zeigtnur ALLE Hauptkategorien ohne Unterkategorie an.

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.

Ichbrauche MAIN-> sub und sobaldich auf sub klicke,solltees dasgleiche sein wie das übergeordnete 'MAIN-> sub'.Ichbrauche,dass sich diese Art von Menünicht ändert,wennich auf MAIN oderein Sub klicke

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

Zunächsteinmalfunktionierenbeide Funktionenfürmicheinwandfrei,Sie verwendenmöglicherweiseeine davonfalsch.Zweitens sollten Siein der Lage sein,dasgewünschte Verhaltenmit den Informationen hier und auf der oben verlinkten Frage zuerreichen.Viel Glück!

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!
