I tried to get a component form from my module. I got the model and then tried to get the form, but the result was empty. I tried to define 'JPATH_COMPONENT' and it was useless.

define('JPATH_COMPONENT', JPATH_SITE . '/components/com_business');

JModelLegacy::addIncludePath(JPATH_SITE . '/components/com_business/models');
$model = JModelLegacy::getInstance('Organization', 'BusinessModel'); //It is correct

$form = $model ->get('Form'); //empty
  • Don't use JPATH_COMPONENT and JPATH_SITE. You only need to use JPATH_SITE

  • Yes, you define the constant, but you need to use JPATH_SITE. JPATH_COMPONENT cannot be used outside the component, so seeing as you're using a module, it won't work ;)

  • JPATH_COMPONENT points to the currently component path. Now if you're in a module that may be used on other component pages - so not only will it not really help - but by defining the constant there you might screw up components who are relying that constant to be the component currently being viewed Commented May 12, 2014 at 23:22

Try to add an additional path where to look for forms before your call to $model->get('Form').


You will need it because getForm calls loadForm (declared on the ancestor class JModelForm) which, before getting the form instance, uses this

JForm::addFormPath(JPATH_COMPONENT . '/models/forms');
JForm::addFieldPath(JPATH_COMPONENT . '/models/fields');

Alternatively you may use JForm::getInstance to get an instance of your form.


  • Thanks for replying, but I have some issues JForm::addFormPath('/components/com_business/models/forms'); JForm::addFieldPath('/administrator/components/com_business/models/fields'); JModelLegacy::addIncludePath(JPATH_SITE . '/components/com_business/models'); $model = JModelLegacy::getInstance('Organization', 'BusinessModel'); $form = $model ->getForm(); print_r($form); //empty

  • JForm::addFormPath('/components/com_business/models/forms'); JForm::addFieldPath('/administrator/components/com_business/models/fields'); $form = JForm::getInstance('Organization'); //throws error "0 JForm::getInstance(name, *string*)"

    This method works, but I think it's not good way $form = new JForm('organization'); $form ->loadFile(JPATH_SITE . '/components/com_business/models/forms/organization.xml'); print_r($form); //correct
