Powershell - Get compatibility from SPweb

Question

I want to do a simple task, I made a script who get all followed site from a user. But I want to filter it with compatibilitylevel.

With few sites, it's Ok, I do :

$currentSite = Get-SPSite -Identity $siteFollowed.Uri.AbsoluteUri
if($currentSite.CompatibilityLevel -eq 15){
   #...
}

But with many sites, it's not Ok because I get SPWeb too... So I have this error :

Get-SPSite : Cannot find an SPSite object with Id or Url: 

When I replace Get-SPSite by Get-SPWeb, I can get this site but I can't get compatibilitylevel....

Object SPSite :
Url                                                     CompatibilityLevel  
---                                                     ------------------  
https://site.fr/sites/test               15                  

Object SPWeb :
Url                                                    
---                                                    
https://site.domain.fr/sites/Collec_SRO/en...

=> No compatibilityLevel...

Do you have an idea to get the sharepoint version? (2010/2013, 14/15)

Answer 1

Try this:

$currentSite = Get-SPSite -Identity $siteFollowed.Uri.AbsoluteUri

  foreach($web in $currentSite.AllWebs){
   $web.Url version is $web.UIVersion #4 or 15
  }
}

You can use GetType() method

$web.GetType().Name 

If it is web it gives you SPWeb otherwise SPSite
