Starting work on views integration for the tripal download api

trpdownload_api_views.php

$view_name = 'tripal_feature_user_feature';
$query = array(
  'uniquename' => '',
  'name' => '',
  'organism' => 'All',
  'type_id' => 677,
);

// First programmatically pull up the view object.
$view = views_get_view($view_name);
$view->set_display('default');
$view->is_cacheable = FALSE;

// Set up paging to keep execution to a managable level.
// This doesn't appear to be working...
$view->display['default']->handler->options['items_per_page'] = 3;
// Next I'll try this:
$view->set_items_per_page(3); // Set to 0 for unlimited.
Then you can set the current page using:
$view->set_current_page(4);

// Add the filter criteria from the query parameters.
// We will use drupal_get_query_parameters() but currently hard-coded for ease of testing.
foreach($query as $k => $v) {
  $view->exposed_input[$k] = $v;
}

// Execute the view.
// Note: this currently executes the whole view with no limits... 
// Perhaps pagering would be sufficient? Perhaps we could grab the query without executing?
// Perhaps we could execute but only grap 2 items unsorted just to generate the query?
$view->execute();

// Add the each result to our file.
foreach ($view->result as $row) {
  fputcsv($FILE, (array)$row );
}
