Error Message: Fatal error: [] operator not supported for strings in D:\wamp\www\drupal7\includes\form.inc on line 2661

Hi all,

Not sure if the problem lies with-in the core or the webform module.I created a new webform and added the following components (see screenshot).

I then browsed to the webforms url (in my case http://localhost/drupal7/content/book-now).

That is where I receive the blank page with the error message above.

I was able to resolve it by modifying the following 3 lines in the file includes/form.inc (starting on line 2657)

Change:

  if (!isset($element['#attributes']['class'])) {
    $element['#attributes']['class'] = array();
  }

To:

  //if (!isset($element['#attributes']['class'])) {
    $element['#attributes']['class'] = array();
  //}

Probably webform.

Yep, seems we're responsible. There's probably a component setting $element['#attributes']['class'] to a string instead of an array. The approach above actually will delete all classes entirely, which isn't what we want.

There's probably a specific component responsible for this behavior, do you know which one it was that started causing this behavior?

Found some missing array() for class #attributes while grepping the code.

Apparently, the ['attributes']['class'] property must be set as an array in the $options array. It will throw this error if it is a string.


$options = array(
    'attributes' => array('class' => array('some-class'))
);
l($name, $url, $options);
