Update a single field from a FormController AJAX method
7
When using an AJAX handler in your FormController, you can update a single field in your form using this:
public function onYourAjaxHandler($recordID)
{
$model = MyModel::findOrFail($recordID);
$model->fieldToUpdate = "new value";
$this->initForm($model);
$fieldMarkup = $this->formGetWidget()->renderField('fieldToUpdate', ['useContainer' => true]);
return [
'#field-id' => $fieldMarkup
];
}If you need to replace the field container, set useContainer => false. If you need to keep the container, set useContainer => true.
Since v452 of OctoberCMS, it is now possible to use the formRenderField() method directly as the "options" argument has been added to it:
$this->formRenderField('fieldToUpdate', ['useContainer'=>false]);
Can you explain how to render that field?
in your code, it seems you have to call an ajaxhandler to render a field. so it is a little confusing.
You can see that this code renders the field.
This is inside an AJAX handler so that it can update a container. So I think you're looking for something else than this. Imagine you have a form with several fields. And when you run onSave or any button action in the form, you want to update just that field without updating the entire form i.e. without refreshing the page--that when you use this provided code. It is called from the data-request of whatever button or element that you are using to cause this element refresh.
Is there a way to refresh the entire form rather than just a single field?
