Woocommerce How to Show Related Categories - php

Question

Good Day, I have the following Code Snippet to help me add custom columns to a plugin the first bit works perfectly but now I would like to add Related Categories to the content (All of this works only in the admin panel) so no shortcode will work
// ADD CUSTOM COLUMN
if( !function_exists('yith_wcbep_add_columns') ) {
function yith_wcbep_add_columns( $columns ) {
$columns['new_column'] = 'Related Categories';
return $columns;
}
add_filter( 'yith_wcbep_default_columns', 'yith_wcbep_add_columns', 99 );
}
this snipped added content to the columns
// ADD CONTECT TO CUSTOM COLUMN
if( !function_exists('yith_wcbep_manage_custom_columns_add_columns_to_new_column') ) {
function yith_wcbep_manage_custom_columns_add_columns_to_new_column( $value, $column_name, $post ) {
if ( 'new_column' == $column_name ) {
$value = 'Custom value'; // This shows the value as Custom value
}
return $value;
}
add_filter( 'yith_wcbep_manage_custom_columns', 'yith_wcbep_manage_custom_columns_add_columns_to_new_column', 10, 3 );
}
as soon as I add this code everything disappears from the columns, this code goes where the Custom value is at
$terms = get_the_terms($product->ID, 'product_cat');
foreach ($terms as $term) {
echo $product_cat = $term->name.', ';
}
UPDATE
if( !function_exists('yith_wcbep_manage_custom_columns_add_columns_to_new_column') ) {
function yith_wcbep_manage_custom_columns_add_columns_to_new_column( $value, $column_name, $post ) {
if ( 'also_column' == $column_name ) {
$prod_cat_args = array(
'taxonomy' => 'product_cat', //woocommerce
'orderby' => 'name',
'empty' => 0
);
//$woo_categories = get_categories( $prod_cat_args );
$woo_categories = get_the_terms( $post->ID, 'product_cat' );
foreach ( $woo_categories as $woo_cat ) {
$woo_cat_id = $woo_cat->term_id; //category ID
$woo_cat_name = $woo_cat->name; //category name
$my_query = "SELECT meta_value FROM wp_termmeta WHERE term_id='$woo_cat_id' AND meta_key=\'crosssell\'";
foreach ($my_query as $row) {
//$value = 'Test - '.$woo_cat->term_id.' - '.$woo_cat->name;
$value = 'Test - '.$row->meta_value;
}
}
}
return $value;
}
but the result keeps being blank, what I'm I doing wrong? if I take out the $my_query section it shows the category and ID but I need to get the CROSSSELL CATEGORY
UPDATED 2 This is the Whole Code
// ADD CUSTOM COLUMN
if( !function_exists('yith_wcbep_add_columns') ) {
function yith_wcbep_add_columns( $columns ) {
$columns['also_column'] = 'Also See...';
return $columns;
}
add_filter( 'yith_wcbep_default_columns', 'yith_wcbep_add_columns', 99 );
}
// ADD CONTECT TO CUSTOM COLUMN
if( !function_exists('yith_wcbep_manage_custom_columns_add_columns_to_new_column') ) {
function yith_wcbep_manage_custom_columns_add_columns_to_new_column( $value, $column_name, $post ) {
if ( 'also_column' == $column_name ) {
$prod_cat_args = array(
'taxonomy' => 'product_cat', //woocommerce
'orderby' => 'name',
'empty' => 0
);
//$woo_categories = get_categories( $prod_cat_args );
$woo_categories = get_the_terms( $post->ID, 'product_cat' );
foreach ( $woo_categories as $woo_cat ) {
$woo_cat_id = $woo_cat->term_id; //category ID
$woo_cat_name = $woo_cat->name; //category name
$my_query = "SELECT meta_value FROM wp_termmeta WHERE term_id='$woo_cat_id' AND meta_key=\'crosssell\'";
foreach ($my_query as $row) {
//$value = 'Test - '.$woo_cat->term_id.' - '.$woo_cat->name;
$value = 'Test - '.$row->meta_value;
}
}
}
return $value;
}
add_filter( 'yith_wcbep_manage_custom_columns', 'yith_wcbep_manage_custom_columns_add_columns_to_new_column', 10, 3 );
}

Answer 1

You can try with the following.
$terms = get_the_terms($product->ID, 'product_cat');
$categories = '';
foreach ($terms as $term) {
$categories .= $product_cat = $term->name.', ';
}
return $categories;
But sill there might some question, in function you used post as parameter, but you use product in this.

Answer 2

after very a long time I got this to work
**$product = wc_get_product($post);
$categories = strip_tags(get_the_term_list( $product->get_id(), 'product_cat', '', ',', '' ));
/*End*/
$value = $categories;**
it shows the categories as it should I added strip_tags to remove the links so now only text remains.
But Now I ran into another problem I cannot get crosssell to show up even if it is there
foreach((get_term_meta( $post->ID, 'crosssell' )) as $category) {
$cat_name = $category->name . '</br>';
$cat_id = $category->term_id . '</br>';
$crosssell = get_term_meta( $cat_id, 'crosssell', true );
}
can display $cat_name and $cat_id no problem but the $crosssell does not display at all
