<?php
namespace App\Form;

trait FormTrait
{
    /**
     * @return self|mixed return model itself if has errors, otherwise returns handled's result.
     * @throws \Throwable rethrows exception if no error specified.
     */
    public function handle()
    {
        try {
            if (!$this->validate()) {

It seems like validate() must be provided by classes using this trait. How about adding it as abstract method to this trait?

                return $this;
            }

            $data = $this->handleInternal();

The method handleInternal() does not exist on App\Form\FormTrait. Did you maybe mean handle()?

            return $data;
        } catch (\Throwable $e) {
            if ($this->hasErrors()) {

It seems like hasErrors() must be provided by classes using this trait. How about adding it as abstract method to this trait?

                return $this;
            }

            throw $e;
        }
    }
}
