Get the distance for use in a custom function

Hi there,

The problem is that you can calculate the straight line distance, but that could be misleading for calculating fuel consumption because the driving distance could be massively different from the straight line.

The distance is calculated in the wpsl_sql filter.

But you can access the template variables using the wpsl_store_meta function like this if you want to do some manipulation to the values in PHP:

add_filter( 'wpsl_store_meta', 'custom_store_meta', 10, 2 );
function custom_store_meta( $store_meta, $store_id ) {
    $distance = $store_meta['distance'];
    // do stuff with the distance variable 
    // ...
    // and then assign it to a new metadata element in the array
    $store_meta['my_custom_distance'] = $distance
    return $store_meta;
}

You can do whatever you want in PHP inside of this function, and then you can output it in the template like <%= my_custom_distance %>

I hope that helps!

Thanks – this is very helpful – I didn’t realise I could just set the variable from the store meta.
