Woccomerce Related and cross-sell categories - php

Question

Good Day,
I have this code below in the code you will find the following $value = 'Custom value'; and $value = 'Custom value2'; Here I need to add Related Categories to a product and cross-sell to a product
$value = 'Custom value'; needs to bring up the category/s the product is in and
$value = 'Custom value2'; needs to bring up the cross-sell categories for that product
// Add Column Names
if( !function_exists('yith_wcbep_add_columns') ) {
function yith_wcbep_add_columns( $columns ) {
$columns['new_column'] = 'Related...';
$columns['new_column2'] = 'Also See...';
return $columns;
}
add_filter( 'yith_wcbep_default_columns', 'yith_wcbep_add_columns', 99 );
}
// Add Column content to Column Names
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';
}
if ( 'new_column2' == $column_name ) {
$value = 'Custom value2';
}
return $value;
}
add_filter( 'yith_wcbep_manage_custom_columns', 'yith_wcbep_manage_custom_columns_add_columns_to_new_column', 10, 3 );
}
see screenshot
Cross-sell can be queried by something like this SELECT meta_value FROM wp_termmeta WHERE term_id='$id' AND meta_key=\'crosssell\'";
but even that only brings up it blank.

This is my solution after spending days and hours on this testing and testing.
First $columns['new_column'];
I added this it brings in the categories
if ( 'new_column' == $column_name ) {
/*Begin*/
$product = wc_get_product($post);
$categories = strip_tags(get_the_term_list( $product->get_id(), 'product_cat', '', ',', '' ));
/*End*/
$value = $categories;
}
then on $columns['new_column2']; I changes it to the following, first i got the prod_cat_args array the i did a foreach on $woo_categories then i got the result on to $cat_term_id = $woo_cat_id; from there I added it to the get_term_meta and it worked!
if ( 'new_column2' == $column_name ) {
/*Begin*/
$prod_cat_args = array(
'taxonomy' => 'product_cat', //woocommerce
'orderby' => 'name',
'empty' => 0
);
$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
}
$cat_term_id = $woo_cat_id;
$crosssell = get_term_meta( $cat_term_id, 'crosssell', true );
/*End*/
$value = $crosssell;
}
// Add Column Names
if( !function_exists('yith_wcbep_add_columns') ) {
function yith_wcbep_add_columns( $columns ) {
$columns['new_column'] = 'Related...';
$columns['new_column2'] = 'Also See...';
return $columns;
}
add_filter( 'yith_wcbep_default_columns', 'yith_wcbep_add_columns', 99 );
}
// Add Column content to Column Names
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 ) {
/*Begin*/
$product = wc_get_product($post);
$categories = strip_tags(get_the_term_list( $product->get_id(), 'product_cat', '', ',', '' ));
/*End*/
$value = $categories;
}
if ( 'new_column2' == $column_name ) {
/*Begin*/
$prod_cat_args = array(
'taxonomy' => 'product_cat', //woocommerce
'orderby' => 'name',
'empty' => 0
);
//$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
}
$cat_term_id = $woo_cat_id;
$crosssell = get_term_meta( $cat_term_id, 'crosssell', true );
/*End*/
$value = $crosssell;
}
return $value;
}
add_filter( 'yith_wcbep_manage_custom_columns', 'yith_wcbep_manage_custom_columns_add_columns_to_new_column', 10, 3 );
}
Hopes this helps any body else
