Add custom Product field and save it

[Ophi]

Using the magento2 devdocs (http://devdocs.magento.com/guides/v2.1/howdoi/customize_product.html) I managed to add a new fieldset and field to the product form. But where I am stuck now is how to save the new value to the database. I have been googling for the last two days and I cannot come up with a solution. How would I do this? Any help is appreciated, thank you.

Hi @Ophi,

Could you please share the code that you implemented to see if there is something missing?


Best regards.

Hi, 

my product_form.xml looks like this: 

<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
  <fieldset name="eintest">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="label" xsi:type="string" translate="true">Custom Stuff</item>
            <item name="sortOrder" xsi:type="number">1</item>
        </item>
    </argument>
        <field name="brand">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="formElement" xsi:type="string">select</item>
                    <item name="value" xsi:type="number">0</item>
                </item>
                <item name="options" xsi:type="object">Vendor\Module\Model\Config\Source\Something</item>
            </argument>
        </field>
  </fieldset>
</form>

and the Something.php class looks like this: 

class Something implements \Magento\Framework\Option\ArrayInterface
{
    /**
     * Options getter
     *
     * @return array
     */
    public function toOptionArray()
    {
        return [['value' => 1, 'label' => __('M2')], ['value' => 0, 'label' => __('M1')]];
    }

    /**
     * Get options in "key-value" format
     *
     * @return array
     */
    public function toArray()
    {
        return [0 => __('M1'), 1 => __('M2')];
    }
}

Thank you!
