IE 10. To clarify, the admin pages themselves load, it is http://example.com/fonts/em-dashicons.eot that returns a 404 (visible in Developer Tools and server logs). See http://i.imgur.com/4CeR4y8.png.

Simpler version:

add_filter( 'wpfc_js_vars', 'my_wpfc_js_vars', 10, 1 );
function my_wpfc_js_vars( $js_vars ) {
	$js_vars['ajaxurl'] = set_url_scheme( $js_vars['ajaxurl'], null );
	return $js_vars;
}

Yes, it is a Genesis Framework child theme. All the custom taxonomy code is in the theme so I can’t just switch to the parent. It’s from the Location with category paste.

Consider the following scenario. There are three locations:

• id=5, location_type=”office”
• id=10, location_type=”fire_station”
• id=15, location_type=”fire_station”

When the AJAX call containing location_types=fire-station is processed:

1. EM_Locations::get() queries the DB and gets an array $results[0 => 5, 1 => 10, 2 => 15]
2. Filter em_locations_get is applied, which unsets $results[0]
3. EM_Object::json_encode() calls PHP’s json_encode()

Because the array passed to json_encode() no longer contains a zero-indexed element, it is encoded as key-value pairs with string keys. From the documentation:

When encoding an array, if the keys are not a continuous numeric sequence starting from 0, all keys are encoded as strings, and specified explicitly for each key-value pair.

That explains the difference in output formats, and means that unless the filter unsets only contiguous locations at the end of $results,[locations_map] won’t work.

If the filter reindexes the array with array_values() (diff) before returning it, the problem seems to be avoided. Is there a more efficient way?
