form submit database

Hello,

I'm new to Sencha, and i've read a lot, how to do things, but i can't get a clue to it.

I want to make a form with multiple text fields.

and if those fields are filled, you can press a button submit, you send the filled field to a database.

How must i do this. i'm blanked out...

The code what i've have is:

Code:

Ext.define('MyDesktop.Modules.Meldkamert.Client.Meldkamert', {  

    extend: 'Ext.ux.desktop.Module',

    id:'meldkamert-win',  
    init : function(){

        this.launcher = {

            text: 'Melding toevoegen',


            iconCls:'icon-meldkamert',


            handler : this.createWindow,


            scope: this


        };


    },

    createWindow : function(){


        var desktop = this.app.getDesktop();


        var win = desktop.getWindow('meldkamert-win');    


        if(!win){


            win = desktop.createWindow({    
                
                        loader: {
                url: './modules/Aris/Client/index.php',
                autoLoad: true,
                loadMask: true,
                contentType: 'html',
                mode: 'iframe'
            },
                renderTo: Ext.getBody(),                                       


                id: 'meldkamert-win',  


                title:'Melding toevoegen',  


                width:1000,       

                height:600,       


                iconCls: 'icon-meldkamert',    
frame:true,
       
        fieldDefaults: {
            msgTarget: 'side',
            labelWidth: 75
        },
        defaultType: 'textfield',
        defaults: {
            anchor: '100%'
        },
       
        items: [{
                fieldLabel: 'Username',
                name: 'username',
                allowBlank:false
            },
            {
                inputType: 'hidden',
                id: 'submitbutton',
                name: 'myhiddenbutton',
                value: 'hiddenvalue'
            }
 
        ],
        buttons: [{
            text: 'Submit',
            handler: function() {
        simple.getForm().getEl().dom.action = '/modules/Aris/Client/olly.php';
            simple.getForm().getEl().dom.method = 'POST';
                simple.getForm().submit();
            }
        }],
                animCollapse:false,


                constrainHeader:true,


                layout: 'fit'
            })


        }


        win.show();


        return win;


    }


});

with kind regards
