I'd like to implement a simple AJAX function locally that allows me to autocomplete node titles of already existing nodes as the user types. To that end, I need the ability to have an API that I can search on node titles. The problem is that when I output raw JSON, it comes surrounded by tags. So, no matter what I do, I keep getting...
<html>
<head>
</head>
<body>
<pre style="word-wrap: break-word; white-space: pre-wrap;"> {json here}</pre>
</body>
</html>
I've tried implementing a custom page template that only outputs content already, that produced the same results. Here is how I am currently doing this, in my module file...
<?php
/**
* Implementation of hook_menu()
*/
function content_relation_menu() {
$items = array();
$items['api'] = array(
'title' => 'Search',
'page callback' => 'content_relation_get',
'access callback' => TRUE,
'type' => MENU_CALLBACK,
);
return $items;
}
function content_relation_get($term = '') {
drupal_add_http_header('Content-Type', 'application/javascript; utf-8');
$var = json_encode(
db_query("SELECT nid,title FROM {node} WHERE title LIKE :title LIMIT 5", array(":title" => $term.'%'))->fetchAll()
);
echo $var;
exit(0);
}
How can I return JUST raw JSON?

function. See here or there for working examples. – keithm Nov 3 '11 at 19:02
