function FormStateInterface::cleanValues

Removes internal Form API elements and buttons from submitted form values.

This function can be used when a module wants to store all submitted form values, for example, by serializing them into a single database column. In such cases, all internal Form API values and all form button elements should not be contained, and this function allows their removal before the module proceeds to storage. Next to button elements, the following internal values are removed by default.

• form_id
• form_token
• form_build_id
• op

Return value

$this
