How do i set my radio button custom option to a default value? Now nothing is selected by default.
I suspect I can add or change something in –>
Mage/Catalog/Block/Product/View/Options/Type/Select.php?

Even tho custom option renderers can be added via layout update by calling addOptionRenderer on product.info.options block, using custom types will never work without rewriting getGroupByType method inside Mage_Catalog_Model_Product_Option class.
You can trick Magento to show your custom type on product view page by doing something like this in local.xml
<catalog_product_view>
<reference name="product.info.options.wrapper">
<block type="foo_bar/options" name="product.info.options" as="product_options" template="catalog/product/view/options.phtml">
<action method="addOptionRenderer"><type>text</type><block>catalog/product_view_options_type_text</block><template>catalog/product/view/options/type/text.phtml</template></action>
<action method="addOptionRenderer"><type>file</type><block>catalog/product_view_options_type_file</block><template>catalog/product/view/options/type/file.phtml</template></action>
<action method="addOptionRenderer"><type>select</type><block>catalog/product_view_options_type_select</block><template>catalog/product/view/options/type/select.phtml</template></action>
<action method="addOptionRenderer"><type>date</type><block>catalog/product_view_options_type_date</block><template>catalog/product/view/options/type/date.phtml</template></action>
<action method="addOptionRenderer"><type>test</type><block>foo_bar/options_test</block><template>foo_bar/options/test.phtml</template></action>
</block>
</reference>
</catalog_product_view>
Block class:
class Foo_Bar_Block_Options extends Mage_Catalog_Block_Product_View_Options
{
public function getOptionHtml(Mage_Catalog_Model_Product_Option $option)
{
if ($option->getType() == 'test') {
$renderer = $this->getOptionRender(
$option->getType()
);
} else {
$renderer = $this->getOptionRender(
$this->getGroupOfOption($option->getType())
);
}
if (is_null($renderer['renderer'])) {
$renderer['renderer'] = $this->getLayout()->createBlock($renderer['block'])
->setTemplate($renderer['template']);
}
return $renderer['renderer']
->setProduct($this->getProduct())
->setOption($option)
->toHtml();
}
}
And this will work until you try to add to cart because that is when getGroupByType is called again and we get a nice error message. :)
Here is the cleanest way I found to set a default value for customizable options :
(Based on answers on this similar question)
Note : I will assume you work on an already created module which I'll call Vendor_Module.
1. Add is_default column to catalog_product_option_type_value table
app/code/Vendor/Module/Setup/UpgradeSchema.php
<?php
namespace Vendor\Module\Setup;
use Magento\Framework\Setup\UpgradeSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
/**
* @codeCoverageIgnore
*/
class UpgradeSchema implements UpgradeSchemaInterface
{
/**
* {@inheritdoc}
* @SuppressWarnings(PHPMD.ExcessiveMethodLength)
*/
public function upgrade(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
if (version_compare($context->getVersion(), '2.0.1') < 0) {
$setup->getConnection()->addColumn(
$setup->getTable('catalog_product_option_type_value'),
'is_default',
[
'type' => \Magento\Framework\DB\Ddl\Table::TYPE_SMALLINT,
'length' => 1,
'unsigned' => true,
'nullable' => false,
'default' => '0',
'comment' => 'Defines if Is Default'
]
);
}
}
}
Note : Don't forget to change the version compared according to your module
2. Define and create a plugin to add the checkbox element in the back office
app/code/Vendor/Module/etc/adminhtml/di.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<type name="Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\CustomOptions">
<plugin name="vendor_module_custom_options_ui_plugin"
type="Vendor\Module\Plugin\CustomOptionsUiPlugin" />
</type>
</config>
app/code/Vendor/Module/Plugin/CustomOptionsUiPlugin.php
<?php
namespace Vendor\Module\Plugin;
use Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\CustomOptions;
use Magento\Ui\Component\Form\Field;
use Magento\Ui\Component\Form\Element\Checkbox;
use Magento\Ui\Component\Form\Element\DataType\Number;
/**
* Data provider for "Customizable Options" panel
*/
class CustomOptionsUiPlugin
{
/**
* Field values
*/
const FIELD_IS_DEFAULT = 'is_default';
/**
* @param \Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\CustomOptions $subject
* @param bool $meta
* @return bool
*/
public function afterModifyMeta(CustomOptions $subject, $meta) {
$result = $meta;
$result[CustomOptions::GROUP_CUSTOM_OPTIONS_NAME]['children']
[CustomOptions::GRID_OPTIONS_NAME]['children']['record']['children']
[CustomOptions::CONTAINER_OPTION]['children']
[CustomOptions::GRID_TYPE_SELECT_NAME]['children']['record']['children']
[static::FIELD_IS_DEFAULT] = $this->getIsDefaultFieldConfig(70);
return $result;
}
/**
* Get config for checkbox field used for default values
*
* @param int $sortOrder
* @return array
*/
protected function getIsDefaultFieldConfig($sortOrder)
{
return [
'arguments' => [
'data' => [
'config' =>[
'label' => __('Default'),
'componentType' => Field::NAME,
'formElement' => Checkbox::NAME,
'dataScope' => static::FIELD_IS_DEFAULT,
'dataType' => Number::NAME,
'additionalClasses' => 'admin__field-small',
'sortOrder' => $sortOrder,
'value' => '0',
'valueMap' => [
'true' => '1',
'false' => '0'
]
],
],
],
];
}
}
Note : Here we use Magento\Ui\Component\Form\Element\Checkbox instead of Magento\Ui\Component\Form\Element\Radio component as it seems Magento never defines it in its Form Elements.
See vendor\magento\module-ui\view\base\ui_component\etc\definition.xml line 112+
3. Overwrite Magento\Catalog\Block\Product\View\Options\Type\Select to check the element which has been chosen as "Default element".
app/code/Vendor/Module/etc/adminhtml/di.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Catalog\Block\Product\View\Options\Type\Select"
type="Vendor\Module\Block\Rewrite\Catalog\Product\View\Options\Type\Select" />
</config>
app/code/Vendor/Module/Block/Rewrite/Catalog/Product/View/Options/Type/Select.php
<?php
namespace Vendor\Module\Block\Rewrite\Catalog\Product\View\Options\Type;
/**
* Product options text type block
*/
class Select extends \Magento\Catalog\Block\Product\View\Options\Type\Select
{
/**
* Return html for control element
*
* @return string
* @SuppressWarnings(PHPMD.CyclomaticComplexity)
* @SuppressWarnings(PHPMD.NPathComplexity)
* @SuppressWarnings(PHPMD.ExcessiveMethodLength)
*/
public function getValuesHtml()
{
$_option = $this->getOption();

$this->setSkipJsReloadPrice(1);

4. Upgrade your module version and update the database
Upgrade your setup_version in app/code/Vendor/Module/etc/module.xml
Update your version in app/code/Vendor/Module/composer.json
Run following commands :
php bin/magento cache:clean
php bin/magento setup:upgrade

Yes you are correct, the custom options are rendered from the file
app/code/core/Mage/Catalog/Block/Product/View/Options/Type/Select.phpTo set a set a radio button custom option to a default value, write this code
before the below code
