I am attempting to implement a dialogue box on the Magento Checkout page which checks the post code field as the user inputs a string. This is not for validation purposes, I simply need it do let the user know if their order will be alegible for free delivery based on the post-code that they enter. I require this to update per key-press.
I am an able programmer but have little experiance with Magento.
Solved! Go to Solution.
Depending if you are using a custome Checkout extension, this is standard Magento functionally if you are using a form of tablerate shipping, You can define what postcodes are eiligibel for free shipping from there.
There is a ton of guides how to set tablerates up, you should be able to google it fairly easily
I hope this helps :-)
You can add custom fields on checkout page by using FME Custom Checkout Fields Magento Extension, i guess dialog box is something that will have to be customized in this module as well, but it works very well.
