製品の主な親カテゴリを取得する

誰か助けてくれませんか.WooCommerce製品の主な親製品カテゴリを見つける方法を探していますか?たとえば、製品はガジェットの下にマークされていますが、それらすべての主な親は電子機器です.

メインの親product_catを示すクラスを各投稿に追加したいので、投稿ごとにこれが必要です.

商品カテゴリはカスタム分類法であり、get_category_parents()を使用して取得することはできません.それらは用語としてリストされています.

よろしくお願いします.

//編集:

これは私がすでに持っているコードです.各投稿でこれを呼び出しており、私の投稿はアーカイブページのようにレンダリングされます.

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; }

誰かを助けるかもしれない代替ソリューションを提供するためだけに:

コード

 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>';

    }

}

使用方法

トップレベル、元の祖先のみ.リンクなし
wc_origin_trail_ancestor();
トップレベル、元の祖先のみ.リンク付き
wc_origin_trail_ancestor(true);
祖先の道;リンクなし
wc_origin_trail_ancestor(false,true);
祖先の道;リンク付き
wc_origin_trail_ancestor(true,true);

メモ

商品に複数のメイン/トップレベルのカテゴリがある場合、または少なくともそれらすべてが表示されない場合は機能しません.
同じレベルの複数のサブカテゴリにも同じことが当てはまります.
関数はそのプロジェクトに必要なすべてを実行するため、上記の点に関してこれ以上のテストは行いませんでした.

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;

これを試すことができます:

 <?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;
  }

?>

3つ以上のレベルのカテゴリをどのように処理しますか?

How would you handle more than two levels of categories?

私は「チェーン」をずっと上る独自の関数を作成しました.私の再帰はあなたが見た中で最高の実装ではないかもしれませんが、それは機能します.

 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;
}
