I am creating a shop for a customer with the Snipcart plugin. There will be a TNT search on the site, using the tntsearch plugin. I checked the docs how to add a custom field, and therefore I added this function to the theme.php:
PHP
// custom TNT Search indexing to add ID field
public function onTNTSearchIndex(Event $e) {
$fields = $e['fields'];
$page = $e['page'];
if (isset($page->header()->snipcart->product_id)) {
$fields->product_id = $page->header()->snipcart->product_id;
}
}
According to docs, this should create a custom field product_id with the content of page->header()->snipcart->product_id, but it doesn’t.
Frontmatter of a page looks like this:
YAML
title: Product Name
snipcart:
product_id: 1005
price: 1990.0
Debug
I debugged and here’s what I got:
PHP
$this->grav[‘log’]->info(‘Header’, (array)$page->header()->snipcart);
// Output: Here I get the Snipcart object as it should be
Header {"product_id":4012,"price":2990} []
PHP
$this->grav[‘log’]->info(‘Product ID’, (array)$page->header()->snipcart->product_id);
// Output: Here I tried to access the object I got from the above output and get nothing
Product ID [] []
