        root: 'rows'

        method: 'GET'
   })
});

Answer 1

There are two possibilities. The first one is to use store baseParams config:

var genres1 = new Ext.data.Store({
    baseParams: {
        param1: 'value1',
        param2: 'value2'
    },
    // ...

The second one is to send them when you are using load method:

genres1.load({params: {param2: 'anotherValue'}});

Note: params will override any baseParams of the same name

So if you setup store with baseParams like in example above and then use load with params the store will request ...?param1=value1&param2=anotherValue.

… and also how would i get at php file

As usual variable passed via the URL parameters – using $_GET:

$param1 = $_GET['param1'];
