Publish product with image

The issue is that it doesn’t set an image. Is there a way to add the image of the product?

– Possible. Which image do you want to set? Know me that image attachment ID.

OK, use this revised code –

add_action( 'wcfmmp_new_store_created', function( $member_id, $wcfmmp_settings ) {
$product_args = array(

'post_title'   => 'Product title',
'post_status'  => 'publish',
'post_type'    => 'product',
'post_excerpt' => 'Description',
'post_content' => 'Here is the content of the product',
'post_author'  => $member_id,
'post_name'    => sanitize_title('Product title')
);
$new_product_id = wp_insert_post( $product_args, true );
update_post_meta( $new_product_id, '_wcfm_product_author', $member_id );

// Set Product Type
wp_set_object_terms( $new_product_id, 'simple', 'product_type' );

// Set Price
update_post_meta( $new_product_id, '_regular_price', '0' );
update_post_meta( $new_product_id, '_price', '0' );

// Featured Image
set_post_thumbnail( $new_product_id, 488 );
}, 50, 2 );

You are always welcome 😊
