Re: Redirect after AJAX request

[NOSLOW]

hey DatacenterHellas,

Your best bet is to not login via an AJAX call. Just set
"standardSubmit: true" in your ExtJS login FormPanel config and call
"MyFormPanel.getForm().submit({method: 'POST'});". Now you can let
CakePHP handler your redirects server-side. On failure, you login page
will just reload. This works very well for me.

Here's some ExtJS code showing details of the login form:

Ext.namespace('CRM');
var crmLogin = {};
Ext.onReady(function(){

    var crm_center = new Ext.Panel({
        region: 'center',
        layout: 'fit',
        bodyBorder: false, border: false, hideBorders: true,
        collapsible: false,
        bodyStyle: 'border-style: none;',
        width: 300,
        items:
        [
            {
                contentEl: 'center1'
            }
        ]
        });

    var viewport = new Ext.Viewport({
        layout: 'border',
        items:
        [
            new Ext.BoxComponent({
                title: 'North',
                region: 'north',
                el: 'north',
                height: 80
            }), new Ext.BoxComponent({
                title: 'South',
                region: 'south',
                el: 'footer',
                height: 30
            }),
            crm_center
        ]
        });

    Ext.QuickTips.init();

    crmLogin = new Ext.FormPanel({
        labelWidth: 70,
        url: '/users/login',
        frame: true,
        title: 'Application Login',
        width: 284,
        bodyStyle: 'padding: 10px 0 5px 20px;',
        defaultType: 'textfield',
        standardSubmit: true,
        monitorValid: true,

        items:
        [
            {
                name: '_method',
                xtype: 'hidden',
                value: 'POST'
            },{
                id: 'CRM-username',
                fieldLabel: 'Username',
                name: 'data[User][username]',
                allowBlank: false
            },{
                id: 'CRM-password',
                fieldLabel: 'Password',
                name: 'data[User][password]',
                inputType: 'password',
                allowBlank: false
            }
        ],

        buttons:
        [
            {
                text: 'Login',
                formBind: true,
                type: 'submit',
                handler: function() {
                    CRM.login(crmLogin);
                    }
            }
        ]
    });

    var win = new Ext.Window({
        layout: 'fit',
        width: 300,
        height: 150,
        closable: false,
        resizable: false,
        plain: true,
        items: crmLogin
        });

    // defer delay seems to help with rendering of login form
(sometimes button is placed too low on form).
    (function(){
        win.show();
        var mapPassword = new Ext.KeyMap('CRM-password', {
            key: 13, // or Ext.EventObject.ENTER
            fn: function() {CRM.login(crmLogin);}
            ,scope: crmLogin
        });

        var mapUsername = new Ext.KeyMap('CRM-username', {
            key: 13, // or Ext.EventObject.ENTER
            fn: function() {CRM.login(crmLogin);}
            ,scope: crmLogin
        });
        }).defer(200);

    (function(){
        crmLogin.getForm().findField('data[User][username]').focus();
        }).defer(700);
    });

CRM.login = function(loginFormPanel) {
    loginFormPanel.ownerCt.hide();
    Ext.MessageBox.wait('Logging in...', 'Please wait...');
    loginFormPanel.getForm().submit({method: 'POST'});
    };
