U can use a JasonStore like you do for grid, you will also need to create a record object, specify fields etc ...

maybe this helps?

myStore = new Ext.data.JsonStore({
    url: 'urlToYourServer',
    autoLoad : true,
        root: 'yourJsonRootElement',
        fields:[
                 {name: "yourKeyField", type: "string"},
                 {name: "yourValueField", type: "string"}
        ]});
myCombo = new Ext.form.ComboBox({
    title: 'yourTitle',
    width: 390,
    allowBlank: 'true',
    readOnly: true,
    triggerAction: 'all',
    store: yourStore, 
    valueField: 'yourValueField', 
    displayField : 'yourKeyField' 
    });

thanks for your reply but .....

you have told me that what will be happen in Js file.. please tell me what is the format of building array in php file....

thanks

use json_encode function to output your populated array. When you fetch your records, they are stored as an array of objects or array of arrays in php. json_encode will format the output that will be readable by Ext component at the client side

You may want to post in php forums, that question is a bit out of scope for this forum.

That said, you might want to check out the tutorials in the wiki, there are few dealing with php. You're going to be sending everything to client using XML or JSON so it's really a matter of you learning how to send one of those data formats from your backend language.

Also check the demos in your SDK, there are php files in there also!
