Plans To Support Filters

[jasonknight]

I have been away awhile on this project. I will have to take a look and see where that functionality is at.

I will be back with the JSON API in about a week. As far as I recall, there is some filter support for some things.

Is this what you are looking for:

   if ( isset( $params['model_filters'] ) && is_array($params['model_filters']) ) {
      JSONAPIHelpers::debug( "Model Filters are Present" );
      JSONAPIHelpers::debug( var_export($params['model_filters'],true) );
      foreach ( $params['model_filters'] as $filter_text=>$filter ) {
        foreach ($filter as $key=>&$value) {
          $value['name'] = substr($wpdb->prepare("%s",$value['name']),1,strlen($value['name']));
        }
        $callback = function ($table) use ($filter) {
            return array_merge($table,$filter);
        };
        JSONAPIHelpers::debug( "Adding filter: " . $filter_text );
        add_filter($filter_text, $callback );
      }
    } else {
      JSONAPIHelpers::debug( "No Model Filters Present" );
    }


It's in the main JSON API class. It allows you to ensure your filters are registered and therefore checked during request.

Shows using it.

Thanks so much for continuing with this. I will give the above a go. I will let you know feedback asap.

I am not sure it is answering your specific situation, this model filter is used to tell the api to load a custom attribute, but that doesn't mean 3rd party plugins will necessarily know about it.

There are significant plans for expansion. Including the ability to pass logic to the call back in the form of a many language implemented in pure PHP. If you look inside the WCAPI models, you may find that there are some filters running, or you could add them, or add the ability to specify filters to run. For instance, what if you added the model_filters and after_load_filters array with a series of strings to call apply_filters with that attribute? Then all you would need to do is add in some logic at attribute load and before save to call model_filters etc. Which is somewhere in the guts already.

Unfortunately, I realize the API is rather daunting at first glance, it's a monstrous effort to compensate for some small issues I have with the internal WooCom API. It's been awhile since I worked on it(mainly it does everything I need so far) so even I am not sure what the hell it does anymore.

[jasonknight]

Can you give me a specific use case so that I can come up with something? Do you want to filter the whole product, i.e. get_product, or do you want to filter independent attributes? What filters are called? Are you using woocommerce attribute filters? The API generally circumvents WooCommerce entirely.
