How to change custom shipping method amount on checkout process. Basically i have created custom shipping method and set $0.00 price for this. On the Checkout page and Shipping method page, i set a text box. when user enter any amount and press submit then i want to set this amount on my custom shipping method price. Can anyone help me?
When you developed the custom shipping method, at that time you set the price in configuration, right? That data stored in core_config table of Magento.
Can you also try to change at that place and also try changing data to the magento event "save_shipping-method"?
