Kannmirbitte jemand helfen? Ich suchenacheiner Möglichkeit,die Hauptkategorie der übergeordneten Produkteeines WooCommerce-Produkts zufinden.Angenommen,das Produktist unter "Gadgets"markiert,aber das übergeordnete Produkt von allenist "Elektronik".

Ichmöchte diespro Beitrag,daichjedem Beitrageine Klasse hinzufügenmöchte,die den übergeordneten Hauptcode product_cat angibt.

Bitte denken Sie daran,dass Produktkategorienbenutzerdefinierte Taxonomien sind undnichtmit get_category_parents() abgerufen werden können.Sie werden als Begriffe aufgeführt.

Vielen Dankim Voraus.

//edit:

Diesist der Code,denichbereits habe. Ich rufeihnbei jedem Beitrag auf undmeine Beiträge werden ähnlicheiner Archivseitegerendert.

function all_cat_classes($post) { $cats = ""; $terms = get_the_terms($post->ID, "product_cat"); $count = 0; $count = count($terms); $key = 0; foreach ($terms as $cat) { $key++; } return $cats; }
Can someone please help me, I'm looking for a way to find the main parent product category of a WooCommerce product? Say, the product is marked under Gadgets, but the main parent of them all is Electronics.

I want this per post, as I want to add a class to each post signifying its main parent product_cat.

Please remember, product categories are custom taxonomy, and cannot be retrieved using get_category_parents(). They are listed as terms.

Thanks in advance.

// edit:

This is the code I have already, I'm calling this on each post and my posts are rendered similar to an archive page.

function all_cat_classes($post) { $cats = ""; $terms = get_the_terms($post->ID, "product_cat"); $count = 0; $count = count($terms); $key = 0; foreach ($terms as $cat) { $key++; } return $cats; }

nur umeine alternative Lösung anzubieten,diejemandem helfen könnte:

Code

 function wc_origin_trail_ancestor( $link = false, $trail = false ) {

    if (is_product_category()) {
        global $wp_query;
        $q_obj = $wp_query->get_queried_object();
        $cat_id = $q_obj->term_id;

        $descendant = get_term_by("id", $cat_id, "product_cat");
        $descendant_id = $descendant->term_id;

        $ancestors = get_ancestors($cat_id, 'product_cat');
        $ancestors = array_reverse($ancestors);

        $origin_ancestor = get_term_by("id", $ancestors[0], "product_cat");
        $origin_ancestor_id = $origin_ancestor->term_id;

        $ac = count($ancestors);

    } else if ( is_product() ) {

        $descendant = get_the_terms( $post->ID, 'product_cat' );
        $descendant = array_reverse($descendant);
        $descendant = $descendant[0];
        $descendant_id = $descendant->term_id;

        $ancestors = array_reverse(get_ancestors($descendant_id, 'product_cat'));
        $ac = count($ancestors);

    }


    $c = 1;
    if( $trail == false ){

        $origin_ancestor_term = get_term_by("id", $ancestors[0], "product_cat");
        $origin_ancestor_link = get_term_link( $origin_ancestor_term->slug, $origin_ancestor_term->taxonomy );

        if($link == true) 
            echo '<a href="'. $origin_ancestor_link .'">';
        echo $origin_ancestor_term->name;
        if($link == true) 
            echo '</a>';

    }else{

        foreach ($ancestors as $ancestor) {
            $ancestor_term = get_term_by("id", $ancestor, "product_cat");
            $ancestor_link = get_term_link( $ancestor_term->slug, $ancestor_term->taxonomy );

            if($c++ == 1) 
                echo '» '; 
            else if($c++ != 1 || $c++ != $ac) 
                echo ' » ';

            if($link == true) 
                echo '<a href="'. $ancestor_link .'">';
            echo  $ancestor_term->name;
            if($link == true) 
                echo '</a>';

        }

        $descendant_term = get_term_by("id", $descendant_id, "product_cat");
        $descendant_link = get_term_link( $descendant_term->slug, $descendant_term->taxonomy );

        echo ' » ';
        if($link == true) 
            echo '<a href="'. $descendant_link .'">';
        echo $descendant->name;
        if($link == true) 
            echo '</a>';

    }

}

wieman

benutzt

nur oberste Ebene,Herkunftsvorfahr; ohne Link
wc_origin_trail_ancestor();
nur oberste Ebene,Herkunftsvorfahr;mit Link
wc_origin_trail_ancestor(true);
Ahnenpfad; ohne Link
wc_origin_trail_ancestor(false,true);
Ahnenpfad;mit Link
wc_origin_trail_ancestor(true,true);

Notizen

funktioniertnicht,wennein Produktmehrere Haupt-/Toplevel-Kategorien hat oder zumindestnicht alle anzeigt;
Gleiches solltefürmehrere Unterkategorien auf derselben Ebene der Fall sein;
Ich habe keine weiteren Tests zu den obengenannten Punkten durchgeführt,da die Funktion allestut,wasichfür dieses Projekt wollte;

just to offer a alternative solution that might help somebody:

code

function wc_origin_trail_ancestor( $link = false, $trail = false ) {

    if (is_product_category()) {
        global $wp_query;
        $q_obj = $wp_query->get_queried_object();
        $cat_id = $q_obj->term_id;

        $descendant = get_term_by("id", $cat_id, "product_cat");
        $descendant_id = $descendant->term_id;

        $ancestors = get_ancestors($cat_id, 'product_cat');
        $ancestors = array_reverse($ancestors);

        $origin_ancestor = get_term_by("id", $ancestors[0], "product_cat");
        $origin_ancestor_id = $origin_ancestor->term_id;

        $ac = count($ancestors);

    } else if ( is_product() ) {

        $descendant = get_the_terms( $post->ID, 'product_cat' );
        $descendant = array_reverse($descendant);
        $descendant = $descendant[0];
        $descendant_id = $descendant->term_id;

        $ancestors = array_reverse(get_ancestors($descendant_id, 'product_cat'));
        $ac = count($ancestors);

    }


    $c = 1;
    if( $trail == false ){

        $origin_ancestor_term = get_term_by("id", $ancestors[0], "product_cat");
        $origin_ancestor_link = get_term_link( $origin_ancestor_term->slug, $origin_ancestor_term->taxonomy );

        if($link == true) 
            echo '<a href="'. $origin_ancestor_link .'">';
        echo $origin_ancestor_term->name;
        if($link == true) 
            echo '</a>';

    }else{

        foreach ($ancestors as $ancestor) {
            $ancestor_term = get_term_by("id", $ancestor, "product_cat");
            $ancestor_link = get_term_link( $ancestor_term->slug, $ancestor_term->taxonomy );

            if($c++ == 1) 
                echo '» '; 
            else if($c++ != 1 || $c++ != $ac) 
                echo ' » ';

            if($link == true) 
                echo '<a href="'. $ancestor_link .'">';
            echo  $ancestor_term->name;
            if($link == true) 
                echo '</a>';

        }

        $descendant_term = get_term_by("id", $descendant_id, "product_cat");
        $descendant_link = get_term_link( $descendant_term->slug, $descendant_term->taxonomy );

        echo ' » ';
        if($link == true) 
            echo '<a href="'. $descendant_link .'">';
        echo $descendant->name;
        if($link == true) 
            echo '</a>';

    }

}

how to use

just toplevel, origin ancestor; without link
wc_origin_trail_ancestor();
just toplevel, origin ancestor; with link
wc_origin_trail_ancestor(true);
ancestor trail; without link
wc_origin_trail_ancestor(false,true);
ancestor trail; with link
wc_origin_trail_ancestor(true,true);

notes

won't work if a product has multiple main-/toplevel-categories, or at least won't show them all;
same should be the case for multiple subcategories on the same level;
I did no further tests concerning above points, because the function does all I wanted for that project;

Sie können Folgendes versuchen:

 <?php
  $term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
  $parents = get_the_terms($term->parent, get_query_var('taxonomy') );

  foreach( $parents as $parent ) {
    echo $parent->name;
  }

?>

You can try this:

<?php
  $term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
  $parents = get_the_terms($term->parent, get_query_var('taxonomy') );

  foreach( $parents as $parent ) {
    echo $parent->name;
  }

?>

Wie würden Siemit mehr als zwei Kategorienebenen umgehen?

How would you handle more than two levels of categories?

Ich habemeine eigene Funktiongeschrieben,um die "Kette" hinaufzugehen.Mein Rekursivistmöglicherweisenicht diebeste Implementierung,die Siegesehen haben,aberesfunktioniert.

 function get_parent_terms($term) {
    if ($term->parent > 0) {
        $term = get_term_by("id", $term->parent, "product_cat");
        if ($term->parent > 0) {
            get_parent_terms($term);
        } else return $term;
    }
    else return $term;
}

# Will return all categories of a product, including parent categories
function all_cat_classes($post) {
    $cats = ""; 
    $terms = get_the_terms($post->ID, "product_cat");
    $key = 0;

    // foreach product_cat get main top product_cat
    foreach ($terms as $cat) {
        $cat = get_parent_terms($cat);
        $cats .= (strpos($cats, $cat->slug) === false ? $cat->slug." " : "");
        $key++;
    }

    return $cats;
}

I wrote my own function to go all the way up the "chain". My recursive might not be the best implementation you've seen, but it works.

function get_parent_terms($term) {
    if ($term->parent > 0) {
        $term = get_term_by("id", $term->parent, "product_cat");
        if ($term->parent > 0) {
            get_parent_terms($term);
        } else return $term;
    }
    else return $term;
}

# Will return all categories of a product, including parent categories
function all_cat_classes($post) {
    $cats = ""; 
    $terms = get_the_terms($post->ID, "product_cat");
    $key = 0;

    // foreach product_cat get main top product_cat
    foreach ($terms as $cat) {
        $cat = get_parent_terms($cat);
        $cats .= (strpos($cats, $cat->slug) === false ? $cat->slug." " : "");
        $key++;
    }

    return $cats;
}
