How to return JSON search results?

Replies: 0

I want to allow my search.php to return JSON, so that I can use Relevanssi with my JS application.

However, I get a headers already sent error when trying to do this because Relevanssi sets this already?

The odd thing is, I use this script on an older site with no problems. It fails however with the latest standard Relevanssi version 3.5.11 (and latest WordPress).

<?php

header('Content-Type: application/json');

$results = array();

if (have_posts()):
  while (have_posts()):
    the_post();
    $results[] = array(
      'permalink' => get_permalink(),
      'title' => get_the_title()
    );
  endwhile;
endif;

echo json_encode($results);

die();

?>

Is there any way to get this to work, or perhaps a better way to do this somehow? I can’t find any information on the matter.

Not sure if this is a bug or not. The exact error is:

Warning: Cannot modify header information – headers already sent by (output started at /Applications/MAMP/htdocs/NBC/wp-content/plugins/relevanssi/lib/search.php:554)

I also wrote this up in a post on StackOverflow if this helps?
