public function FormAssemblyRequest::getFormMarkup in FormAssembly 7

Retrieve the HTML for a FormAssembly form.

The FA API recognizes query parameters passed on the rest URL and will use them to pre-fill fields in the returned form markup. Here we fold in parameters configured via formassembly_form() and expose the hook hook_formassembly_form_params_alter(&$params) to allow modules to modify the passed parameter list.

Parameters

$entity: Entity form object.

Return value

string HTML representation of the form.

  // Replace any tokens found in the parameter pair values.
