Source Model for Catalog product tye

Question

I am creating a bespoke extension and I want to allow the admin to choose to restrict by product types eg Simple, Configurable, Bundle etc

The issue is I am not sure what source model to use.

I have the following code in my system.xml

<field id="product_types" translate="label" type="multiselect" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
 <label>Product Type</label>
 <source_model></source_model>
 <comment>Restrict defined product types</comment>
</field>

Could anyone advise which source model I need to use so that the options in the multi-select are the product types eg Simple, Configurable, Bundle etc

You can create a custom source model as describe below.

Assume, your are using custom extension name "Vendor_Module"

File : ProductType.php under app/code/Vendor/Module/Model/Source

<?php
namespace Vendor\Module\Model\Source;
class ProductType implements \Magento\Framework\Data\OptionSourceInterface
{
 //*
 // @var \Magento\Catalog\Model\ProductTypeList
 //
 protected $_productTypeList;
 //*
 // Constructor
 //
 // @param \Magento\Catalog\Model\ProductTypeList
 //
 public function __construct(
 \Magento\Catalog\Model\ProductTypeList $productTypeList
 )
 {
 $this->_productTypeList = $productTypeList;
 }
 /**
 * Get options
 *
 * @return array
 */
 public function toOptionArray()
 {
 $options[] = ['label' => '', 'value' => '']; 
 $productType = $this->_productTypeList->getProductTypes();
 foreach ($productType as $pType) {
 $options[] = [
 'label' => $pType->getName(),
 'value' => $pType->getLabel(),
 ];
 }
 return $options;
 }
}

update your system.xml as follows.

File : system.xml:

 ............................
<field id="product_types" translate="label" type="multiselect" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
 <label>Product Type</label>
 <source_model>Vendor\Module\Model\Source\ProductType</source_model>
 <comment>Restrict defined product types</comment>
</field>
 ............................
