I have created a custom shipping method following this tutorial:


Now I would need to add a couple of extra variables to admin configuration, and save it in any place to use it later when the checkout is done. How can I do that? Thanks!

  • Do you want to add some configuration In STORES > Configuration -> SALES section -> Shipping Methods ?? Oct 11, 2018 at 18:42
  • hey @AdityaShah. Yes I would want that. Really I need to save a couple of config data to use it later in the checkout process, I think this is a good place, but it also could be in other place. Oct 11, 2018 at 18:49

You can add more field like below in your system.xml under group tag with id="simpleshipping" in above module-

<field id="custom_variable" translate="label" type="text" sortOrder="100" showInDefault="1" showInWebsite="1" showInStore="1" canRestore="1">
      <label>Custom Variable</label>

Now you can retrieve value of this field in any file like block or model or controller like this --

protected $_scopeConfig;

public function __construct(
     \Magento\Store\Model\ScopeInterface $scopeInterface,
    $this->_scopeConfig = $scopeInterface;

Then in your class' method you can call the following:

$this->scopeConfig->getValue('carriers/simpleshipping/custom_variable', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
