Need help with module "views node feed"

I think the http://drupal.org/project/views_datasource module does this much easier-you just select a style for the view. Might be worth a try.

I would create a custom module. You can use the query from views to put into your module. Then you can build the array exactly as you want. You will need to create a menu callback so that when you go to: some/address/json it fires your function and returns drupal_json($your_array);

There are a load of tutorials about how to create a module. Basically create your module folder and in that you need your_module.info and your_module.module, you will also need to read about doing queries in Drupal.

I've created some code below which should be all you need to do this.

If you need to pass some values to your query then you can use %, and then accordingly set 'page arguments' e.g. if you wanted to pass the first and second argument in the url we would put 'page arguments' => array(0, 1), below I am passing the 3rd argument.

function your_module_menu() {
$items[some/address/%/json'] = array(
'page callback' => 'your_function',
'access callback' => TRUE,
'page arguments' => array(2),
'type' => MENU_CALLBACK,
);
return $items;
}

function your_function($argument) {
$sql = YOURSQL;
$result = db_query($sql, $argument);
// Now do some stuff with the result array to create your own array
return drupal_json($your_output array);
}

Just read your earlier posts. What might help you is to use the Devel module. With the Devel module enabled you can do stuff like dsm($nodes). I wouldn't bother trying to format your json output yourself. I would build the array in php and then use print drupal_json($your_array); to output the array in json.

In your views template (if that's what you're using) you would want to do something like:

$output_array = array();
foreach ($nodes as $node) {
$output_array[] = array(
'title' => $node->title,
'results' => array(
array('/metal/1', 'Disturbed - The Game', 'icons/metal.png),
array('/metal/2', 'Marilyn Manson - The Beautiful People', 'icons/metal.png'),
),
);
}
print drupal_json($output_array);

If you do:
dsm($nodes);
dsm($output_array);
you can see the structure of your arrays using Krumo (with the Devel module)
