Saving post content into product meta field

I have Books as Products in woocommerce and chapters as posts in wordpress blog. For example, “Song of Ice and Fire” is a woocommerce product while “A Clash of the Kings” is a post in a category in wordpress blog.

The only information A Clash of the Kings has in the content is link to the amazon website.

Now, I want to grab the content (more or less links) from each post within a given wordpress category and save them into the repeater field in my Product page.

I’m stuck as I can’t get how to save the content into repeater meta fields. Is there anyone who could help me out?
************
This is the code

<?php
$scat = get_the_term_list( $id_product,”scat”); /* I add this ‘scat’ through the product page in Admin Panel by using Custom Taxonomy. It will be the ID of the wordpress category */

// query
$query = new WP_Query( array( ‘cat’ => $scat ) );

?>
<?php if( $the_query->have_posts() ): ?>

<?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>

<?php the_content(); ?> /* Now I’m stuck here */

<?php endwhile; ?>

<?php endif; ?>

<?php wp_reset_query(); // Restore global post data stomped by the_post(). ?>

Here’s some directions for ya

1) the function get_the_term_list() returns the HTML https://codex.wordpress.org/Function_Reference/get_the_term_list. the function you are looking for is get_the_terms() https://developer.wordpress.org/reference/functions/get_the_terms/

2) when you initialize the WP_Query, take a look at what types of parameter you should pass to search in the category https://codex.wordpress.org/Class_Reference/WP_Query#Category_Parameters. ‘category__in’ requires an array of term ids. And ‘cat’ requires a term id.

3) use get_the_content() to retrieve the post content https://developer.wordpress.org/reference/functions/get_the_content/

4) to update repeater field, you can either use update_field or update_sub_field functions.

https://www.advancedcustomfields.com/resources/update_sub_field/

these should get you going with what you are trying to do.

Cheers!
