Hi guys

I was wondering if it is possible to load libraries via the #attached property from render arrays.

Cheers

Not sure if this is what you meant exactly but this is an example that works:

Thanks for the link, it works with libraries registered with Drupal Core library functionality, but can't get it to work with libraries registered with Library Api module.

Yes it's possible:

<?php
$form
['myelement']['#attached']['libraries_load'][] = array('myAwesomeLibrary');
?>

So, in short, just add a libraries_load key to your #attached array, with as value an array of parameters to pass to libraries_load().

Note that this:

<?php
$form
['myelement']['#attached']['libraries_load'][] = array('myAwesomeLibrary');
?>

Should be this:

<?php
$form
['myelement']['#attached']['libraries_load'][] = 'myAwesomeLibrary';
?>

@Jaypan:

No it should not ;-)

See drupal_process_attached():

<?php
// Add additional types of attachments specified in the render() structure.
// Libraries, JavaScript and CSS have been added already, as they require
// special handling.
foreach ($elements ['#attached'] as $callback => $options) {
  if (
function_exists($callback)) {
    foreach (
$elements ['#attached'][$callback] as $args) {
     
call_user_func_array($callback, $args);
    }
  }
}
?>

The second argument to call_user_func_array() should be an array :-).

Oh, you're right. I had an additional array layered in my code I was working on.
