Always wondered how to generate forms in modules so that I could use contao’s form generator – Instead of doing that I had to write the forms myself. Now I know how to do it.
If you know the id of your form you can select it using:
$obj = new \stdClass(); $obj->form = $id;
If you do not know the id of your form, you can get the id using the alias (so yeah, you have to know the alias or the id):
$model = \FormModel::findByAlias($alias); $id = $model->id; $obj = new \stdClass(); $obj->form = $id;
Now that you’ve got the id, you can create the form:
$form = new \Form($obj);
and finally render it:
$formRendered = $form->generate();
echo it or assign it to your Template.
