Adding a 'Pre-Order' Option to Magento 2's Backorder Settings

Magento 2 allows backorders, but it doesn’t include a built-in 'Pre-Order' option. By customizing the backorder settings, you can add a 'Pre-Order' status, letting customers place orders for out-of-stock products in advance.

Adding a 'Pre-Order' Option to Magento 2's Backorder Settings

How to Retrieve Applied Rule IDs for an Item in a Magento 2 Order?

To introduce a 'Pre-Order' option in Magento 2's backorder settings, you'll need to modify the system by creating a plugin that adds this new option to the existing backorder statuses.

Steps to Add 'Pre-Order' to Backorder Options:

Access Advanced Inventory Settings:

In the Magento admin panel, navigate to the product page.
Click on the 'Advanced Inventory' link to open the inventory settings modal.

Create a Plugin to Add 'Pre-Order':

Develop a plugin that extends the backorder options by adding a 'Pre-Order' status.
This involves creating specific files in your Magento installation:

di.xml: Defines the plugin and its target.
PreOrderOption.php: Contains the logic to append the 'Pre-Order' option.

Sample Code Implementation:

di.xml (located at app/code/YourVendor/Preorder/etc/di.xml):

<?xml version="1.0"?>

</type>

</config>

PreOrderOption.php (located at app/code/YourVendor/Preorder/Plugin/PreOrderOption.php):

<?php

namespace YourVendor\Preorder\Plugin;

use Magento\CatalogInventory\Model\Source\Backorders;

class PreOrderOption

{

/**

* Add new 'Pre-Order' option to backorders

* @param Backorders $subject

* @param array $options

* @return array

public function afterToOptionArray(Backorders $subject, array $options)

{

$options[] = [

'value' => 50,

'label' => __('Allow Pre-Orders')

];

return $options;

}

Important Considerations:

Option Value: The 'value' (e.g., 50) assigned to the 'Pre-Order' option should be unique and not conflict with existing backorder statuses.
Customization: You can modify the 'value' and 'label' to fit your specific requirements.
File Paths: Ensure that the file paths match your Magento installation's directory structure.

By implementing this plugin, the 'Pre-Order' option will become available in the backorders dropdown on the product inventory settings page, allowing you to manage pre-order statuses directly from the admin panel.
