How to use a Google Map field address in emails & success messages

When using merge tags to render values in email notifications and success messages, the Google map field will return an escaped JSON encoded string as a value. If you only need a fragment of the payload – e.g; the address – then you may register a custom merge tag that returns the desired value:

<?php 

add_filter( 'af/merge_tags/resolve', function ( $output, $tag ) {

  // Check for the custom merge tag
  if ( 'google_map_address' != $tag ) {
    return $output;
  }

  // Get value from submission. This will be an escaped JSON string.
  $value = af_get_field( 'google_map' );

  // Remove slashes so it is ready for decoding.
  $value = wp_unslash( $value );

  // Decode JSON to array.
  $value = json_decode( $value, true );

  return $value['address'];

}, 10, 2 );
