Hello,

I Have a store with extraParams who contain an ID. I would like to pass the ID at the end of the url store.
I have:
Code:
WPApp.stores.DirectoryCategoryListStore = new Ext.data.Store({
    model: "WPApp.models.DirectoryCategoryListModel",
    proxy: {
        type: 'ajax',
        url: "http://localhost:8888/WPapp/app/php/getCategoryList.php",
        reader: {
            type: 'json'
        }
    },
    setId: function (id) {
        this.itemId = id;
    },
    extraParams: {
        id: this.itemId,
    },
    autoLoad: true
});
I would like to have if this.itemId = 2
HTML Code:
url: "http://localhost:8888/WPapp/app/php/getCategoryList.php?id=2"
when i put the url like that with raw values, it's working.
i tried to concat the variable to URL, and create a new extra param with the url, but don't work.

In my PHP file, the URL, i have:
Code:
    $id = $_GET['id'];
    $request = "SELECT * FROM CategoryList WHERE IDBASELIST = $id";
    echo (getJsonString($request, $dbName));
I don't really understand how i can give this extra Params to my URL
Someone can help me please?
