How to send / retrieve Data in Magento Controller, Model and Block

Question

I am creating a custom module in Magento. I want to know how to pass data from the .phtml file to the Controller and then to the Model.

Just want to know the structure of passing the data in the magento MVC structure.

Answer 1

Simple you can call you controller from phtml like

Mage::getBaseUrl()/Modulename/Controllername/methodname

and to call Model

Mage::getModel('modulename/modelname')->methodname()

---

Example For controller

Mage::getBaseUrl()/priceconfig/index/checkcountryrate?price=$price

Where priceconfig is my module-name and index is my controller name and checkcountryrate is my method

Example For Model

Mage::getModel('catalog/product')->load(1)
