I run EE v2.10.1 with Store 2.5.1. I get the following error when logged in. This error doesn't happen all of the time which puzzles me even more..

Fatal error: Call to undefined function Store\Model\form_dropdown() in [omited]/system/expressionengine/third_party/store/src/Model/ProductModifier.php on line 84

Any clue anyone?

form_dropdown() method is default EE method lies on "form" helper.

Go to the file [omited]/system/expressionengine/third_party/store/src/Model/ProductModifier.php and write this line at the beginning of function ee()->load->helper('form');

  • Like this?> public function toTagArray() { ee()->load->helper('form'); $attributes = parent::toTagArray(); etc..

  • Works! I have voted up your answer thx! It seems however strange that this would be required though. Could it be this error hapens because of clustered hosting?
