Methods

add_argument_to_query()

Add the filtering flag to the queries.

public add_argument_to_query(array<string|int, mixed> $args) : array<string|int, mixed>
Parameters
$args : array<string|int, mixed>
Return values
array<string|int, mixed> —

add_fallback_elements()

Add an hidden div that contains the total number of products that the table's query has produced.

public add_fallback_elements(string $output, array<string|int, mixed> $options, array<string|int, mixed> $products) : string

We need this because there's no other way to retrieve the number that we need to show inside our sidebar filters.

Parameters
$output : string

original output

$options : array<string|int, mixed>

menu options

$products : array<string|int, mixed>

list of products inside the query.

Return values
string —

cache_query()

Cache the prefilled query so that it can then be used at a later point when sending back an ajax response.

public cache_query(WP_Query $query, Collection $filters, string $orderby, array<string|int, mixed> $post_ids) : void
Parameters
$query : WP_Query
$filters : Collection
$orderby : string
$post_ids : array<string|int, mixed>

get_query_argument_id()
