Manipulating data from ACF field before adding to JSON response

I have an ACF field that is working fine for adding info with each store. I can also pull the field out into the template with:
```
add_filter( 'wpsl_frontend_meta_fields', 'custom_frontend_meta_fields' );

function custom_frontend_meta_fields( $store_fields ) {
    $store_fields['products'] = array(
        'name' => 'products_at_this_store',
        'type' => 'text'
    );
    return $store_fields;
}
```
However I need to manipulate the data with PHP before sending it to the JSON Response as it is a serialised field: {i:0;s:2:”95″;i:1;s:2:”97″;i:2;s:2:”96″};

How can I do that?

I have managed to do this now, but only by hacking a core plugin file.

I added an option to the switch($meta_type) {} in class-frontend.php to handle the ACF products list:

 case 'products':
$post_objects = get_field('products', $store->ID);
$products     = '<h4>Products stocked</h4>';
if ( $post_objects ) {
  $products.='<ul>';
  foreach ( $post_objects as $post_object ) {
    $products .= '<li>'.get_the_title( $post_object->ID ) . '</li>';
  }
  $products.='</ul>';
}
$meta_data =  stripslashes( $products ) ;
break;

Obviously this isn’t ideal. Is there a better way of doing this?

If you want to include custom data in each store, then you can do so with this filter.


add_filter( 'wpsl_store_meta', 'custom_store_meta', 10, 2 );

function custom_store_meta( $store_meta, $store_id ) {

    $your_custom_data = your_function();
    
    $store_meta['extra_data'] = $your_custom_data;
    
    return $store_meta;
}

Then include the custom key in the search results template with this filter.


$listing_template .= "\t\t\t" . '<% if ( extra_data ) { %>' . "\r\n";
$listing_template .= "\t\t\t" . '<p><%= extra_data  %></p>' . "\r\n";
$listing_template .= "\t\t\t" . '<% } %>' . "\r\n";
