yii using multiple themes - yii

I want to set up at least two different themes for guest and for admin user. It also would be handy to have the option to set up different theme for different type of user. For example premium user would see things differently to guest and to admin.
When I try following in /config/main.php:
'theme'=>(Yii::app()->user->isGuest)?'bluebox':'classic',
it always evaluates as false. I guess engine is not initialized yet. Is there any way how to achieve this?

You can't configure multiple themes in config.php file, you can do this in your controller.
public function init()
{
if(Yii::app()->user->isGuest)
Yii::app()->theme = 'bluebox';
else
Yii::app()->theme = 'classic';
parent::init();
}

Here's a thread on how to change the theme on the fly:

Prestashop 1.6 Create Module to Display Carrier Filter

My Prestashop-based site is currently having an override for AdminOrdersController.php, I have placed it in override folder.
From the link provided below, it is perfectly working fine to add a Carrier filter which is not available in Prestashop 1.6 now. I have tried the solution and it is working perfectly.
Reference: Adding carrier filter in Orders page.
Unfortunately, for production site, I have no access to core files and unable to implement as such. Thus, I will need to create a custom module. Do take note that I already have an override in place for AdminOrdersController.php. I would like to tap on this override and insert the filter.
I have managed to create a module and tried placing an override (with the code provided in the URL) in mymodule/override/controller/admin/AdminOrdersController.php with the carrier filter feature.
There has been no changes/effect, I am baffled. Do I need to generate or copy any .tpl file?
Any guidance is greatly appreciated.
Thank you.
While the answer in the linked question works fine the same thing can be achieved with a module alone (no overrides needed).
Admin controllers have a hook for list fields modifications. There are two with the same name however they have different data in their params array.
actionControllernameListingFieldsModifier executes before a filter is applied to list.
actionControllernameListingFieldsModifier executes before data is pulled from DB and list is rendered.
So you can add fields to existing controller list definition like this in your module file:
public function hookActionAdminOrdersListingFieldsModifier($params) {
if (isset($params['select'])) {
$params['select'] .= ', cr.name';
$params['join'] .= ' LEFT JOIN `'._DB_PREFIX_.'carrier` cr ON (cr.`id_carrier` = a.`id_carrier`)';
}
$params['fields']['carrier'] = array(
'title' => $this->l('Carrier'),
'align' => 'text-center',
'filter_key' => 'cr!name'
);
}
Because array data is being passed into $params array by reference you can modify them in your hook and changes persist back to controller. This will append carrier column at the end of list.
It is prestashop best practice to try and solve problems through module hooks and only if there is really no way to do it with hooks, then do it with overrides.
Did you delete /cache/class_index.php ? You have to if you want your override to take effect.
If it still does not work, maybe you can process with the hook called in the AdminOrderControllers method with your new module.

Access Roles in DNN Hotcakes Checkout Views

I'd like to be able to show/hide certain payment methods based on user roles.
In Hotcakes under the "_DisplayPaymentMethods" view set I see a switch statement with "payMethod.MethodId" as the expression. Inside each case I'd like to set an if statement that checks if the current user has "x" role.
How can I access the user roles from this view set?
You'll find the answer in the Hotcakes Commerce documentation area. I've included it here for posterity on SO as well.
Security roles are used for a large number of purposes in both the e-commerce and CMS parts of your website. On occasion, you might want to re-purpose these roles to do something dynamic with your views. One example might be to only show the Add to Cart button to a specific role. We'll use that use case for this example.
First, you'll need a plan. In this plan, we're going to make the Add to Cart button available to all people that are logged in and part of the "VIP-Customer" security role. (This isn't a built-in role. It's made-up for this code sample. You can create and use whatever roles that you want.)
Add the code below to the header area of the view that you want to edit, such as the _ProductDetails.cshtml view.
#functions
{
private bool IsVipCustomer()
{
var customer = DotNetNuke.Entities.Users.UserController.Instance.GetCurrentUserInfo();
if (customer != null && customer.UserID > 0)
{
return customer.IsInRole("VIP-Customer") || customer.IsInRole("Administrators");
}
return false;
}
}
In this code sample below, we're checking to see if the role matches what we expect. If it does, we show the Add to Cart button. You can add and use this code anywhere you want, as long as it has the function we created above in the same view file.
#if (IsVipCustomer())
{
<input type="submit" id="addtocartbutton" value="#Localization.GetString("AddToCart")" class="dnnPrimaryAction largeButton fullCartButton" />
}
We hope this helps you as a baseline example for doing anything dynamic with views that involves the security roles in the CMS.

Yii global variables and setting issue

I am developing a social networking website using Yii. While frequently using the following things I am having great data manageability issue.
- User ID
- Current user ID (the user which profile is the owner viewing)
- Is owner???
where can I define these things.
I would something like
if(Yii::app()->owner==ME){
//do something
}
// and similarly
if($this->isMyFreind(<Current user ID>){
}
// $this(CanIView()){
}
I want these functions to be public for any page? But how?
In other words
Where can I put my library which contains my own favorite functions like text shortening, image cropping, date time format etc etc??
In Yii, you can do achieve this by making a class (under protected/compoents) which inherits
CApplicationComponent
class. And then you call any property of this class globally as a component.
class GlobalDef extends CApplicationComponent {
public $aglobalvar;
}
Define this class in main config under components as:
'globaldef' => array('class' => 'application.components.GlobalDef '),
And you can call like this:
echo Yii::app()->globaldef->aglobalvar;
Hope that can help.
According to the MVC model, things like image cropping or date time formats would go in models. You would simply create models for that.
I usually use a globals.php file with all my common functions
In the index.php (yip the one in the root):
$globals='protected/globals.php';
require_once($globals);
I can then call my global functions anywhere. For example, I shorten certain Yii functions like:
function bu($url=null){
static $baseUrl;
if ($baseUrl===null)
$baseUrl=Yii::app()->request->baseUrl;
return $url===null ? $baseUrl : $baseUrl.'/'.ltrim($url,'/');
}
So I can then call the Yii::app()->request->baseUrl by simply calling bu()

Sending more data to changeIdentity in CWebUser by overriding it?

Disclaimer: Complete beginner in Yii, Some experience in php.
In Yii, Is it OK to override the login method of CWebUser?
The reason i want to do this is because the comments in the source code stated that the changeIdentity method can be overridden by child classes but because i want to send more parameters to this method i was thinking of overriding the login method too (of CWebUser).
Also if that isn't such a good idea how do you send the extra parameters into the changeIdentity method.(By retrieving it from the $states argument somehow ??). The extra parameters are newly defined properties of UserIdentity class.
It is better to first try to do what you wish to do by overriding components/UserIdentity.php's authenticate method. In fact, that is necessary to implement any security system more advanced than the default demo and admin logins it starts you with.
In that method, you can use
$this->setState('myVar', 5);
and then access that anywhere in the web app like so:
Yii::app()->user->getState('myVar');
If myVar is not defined, that method will return null by default. Otherwise it will return whatever it was stored as, in my example, 5. These values are stored in the $_SESSION variable, so they persist as long as the session does.
UPDATE: Okay, took the time to learn how this whole mess works in Yii for another answer, so I'm sharing my findings here as well. The below is mostly copy pasted from a similar answer I just gave elsewhere. This is tested as working and persisting from page to page on my system.
You need to extend the CWebUser class to achieve the results you want.
class WebUser extends CWebUser{
protected $_myVar = 'myvar_default';
public function getMyVar(){
$myVar = Yii::app()->user->getState('myVar');
return (null!==$myVar)?$myVar:$this->_myVar;
}
public function setMyVar($value){
Yii::app()->user->setState('myVar', $value);
}
}
You can then assign and recall the myVar attribute by using Yii::app()->user->myVar.
Place the above class in components/WebUser.php, or anywhere that it will be loaded or autoloaded.
Change your config file to use your new WebUser class and you should be all set.
'components'=>
'user'=>array(
'class'=>'WebUser',
),
...
),

Connection strings for different users

How do I send two users coming from different company domains to different SQL databases to retrieve/store data? I use Application variables to store the connection strings and the Request.ServerVariables("LOGON_USER") variable is an effective way to get the domain name. Is the GLOBAL.AsA file to be modified? The table names are exactly the same in both databases, so I think changing the connection strings based on the user domain should do the trick.
User A with domain ABC --> Application("ConnecttoDB") send to database A
User B with domain XYZ --> Application("ConnecttoDB") send to database B
I have roughly 900+ classic ASP pages so I would really hate to add a bunch of IF-THEN's to choose the correct database in each page. All ideas are greatly appreciated!
UPDATE: To make things simple I'm envisioning one single Application variable (i.e.: ConnecttoDB) However, wouldn't its value be constantly changing every time a different user gets access and altering page results?
You can't use an Application variable since that's shared across all users. This would be a race condition. Instead you'll need to use the Session object to store the connection and then use that whenever you need to connect to the DB.
myDB=Server.CreateObject("ADODB.Connection")
StrConn = Session("ConnecttoDB")
myDB.Open StrConn
Here's one way of doing it:
I'm guessing that your classes for your web page codebehind files inheit the Page class. Create a new class file in your ASP.net project that inherits Page. Call it JorgePage. Then, make your codebehind file classes inherit JorgePage.
In JorgePage, write two functions:
private string getUsersDomain()
{
// returns the user's domain
}
protected string getUsersConnectionString()
{
switch (getUsersDomain().ToUpper())
{
case "ABC":
return Application("ConnecttoDB_ABC");
break;
case "xYZ":
return Application("ConnecttoDB_XYZ");
break;
}
}
Now, the function getUsersConnectionString() is available in the context of all your pages and returns the correct connection string. Furthermore, you have the code in only one place, so if you need to change the logic later, you can do so easily.
Given that you're using classic ASP, you can define a function to return the appropriate connection string in another .asp file and use the #include directive to add it to all your pages.
