Answer 1

I managed to fix the problem.

1. Proper way to create a cart:

   if (!$this->context->cart->id)
   {
       if (Context::getContext()->cookie->id_guest)
       {
           $guest = new Guest(Context::getContext()->cookie->id_guest);
           $this->context->cart->mobile_theme = $guest->mobile_theme;
       }
       $this->context->cart->add();
       if ($this->context->cart->id)
           $this->context->cookie->id_cart = (int)$this->context->cart->id;
   }
   

2. Add customization

   $this->product = new Product(1, true, (int)($this->context->cookie->id_lang));
   
   $authorized_text_fields = array();
   
   if (!$field_ids = $this->product->getCustomizationFieldIds())
           return false;
   
   foreach ($field_ids as $field_id)
       if ($field_id['type'] == Product::CUSTOMIZE_TEXTFIELD)
           $authorized_text_fields[(int)$field_id['id_customization_field']] = 'textField'.(int)$field_id['id_customization_field'];
   
       $indexes = array_flip($authorized_text_fields);
       foreach ($_POST as $field_name => $value)
           if (in_array($field_name, $authorized_text_fields) && !empty($value))
           {
               if (!Validate::isMessage($value))
                   $this->errors[] = Tools::displayError('Invalid message');
               else
               $this->context->cart->addTextFieldToProduct($this->product->id, $indexes[$field_name], Product::CUSTOMIZE_TEXTFIELD, $value);
           }
           else if (in_array($field_name, $authorized_text_fields) && empty($value))
               $this->context->cart->deleteCustomizationToProduct((int)$this->product->id, $indexes[$field_name]);
   

3. Get the customizations

   $texts = $this->context->cart->getProductCustomization($this->product->id, Product::CUSTOMIZE_TEXTFIELD, true);
   $text_fields = array();
   foreach ($texts as $text_field)
       $text_fields['textFields_'.$this->product->id.'_'.$text_field['index']] = str_replace('<br />', "\n", $text_field['value']);
   

Answer 2

The most simple to validate a cart:

// Validate the object cart $this->context->cart->save(); $this->context->cookie->id_cart = (int)$this->context->cart->id;

the save() method upate the cart if exists or create a new if not. Then force the cookie to have the same id.
