php - Yii Session Variable -

-

I am working with session variables in the YII framework.

I created session variables in Site Controller

As 

  Public Function Authentication () {$ user = UserSignupForm :: model () - & Gt; FindByAttributes (array ('emailid' => = this- & gt; username)); If ($ user === empty) $ this- & gt; ErrorCode = self :: ERROR_USERNAME_INVALID; And if ($ user- & gt; password! == ($ this- & gt; password)) $ this- & gt; ErrorCode = self :: ERROR_PASSWORD_INVALID; Else {$ connection = Yii :: app () - & gt; Db; $ Sql ​​= "Choose roles from the ralinom, where the role has been played (to play a role from Uire's where the user-in-the-user select from user iFO, where e-mail id = 'user-> e-mail id');"; $ Command = $ connection- & gt; CreateCommand ($ sql); $ Roles = $ command- & gt; Query still (); // $ this- & gt; Setstate ('roles', $ roles ['0'] ['theft']); // $ this- & gt; Setstate ('user', $ user- & gt; username); $ This- & gt; ErrorCode = self: ERROR_NONE; Yii :: app () - & gt; Session ['role1'] = $ roles ['0'] ['rolename']; ['Role1'] session ;; & Gt - $ Yii :: App () s =}}   
 I am getting the value of the session within this controller.  
 But I am redirecting another controller. Its session variable has not been placed and it does not have a distinction.    
 
 
 I think this link can help you:  < P>  
 Basically:  
     
  1.  Enter the ID from the session:  
  2.  Extension of CWebUser or other visible folder in component to create a class web application Something like this:   
      
      Class WebUser did not increase the CDB user {// store model to replicate the query. Private $ _model // Return name first // it's Yii :: app () -> & gt; User- & gt; Use first_name function getFirst_Name () {$ user = $ this- & gt; Load User (Yii: App () -> User- & gt; ID); $ User- & gt; Return to first_name; } // Return the first name // it's Yii :: app () -> & gt; User- & gt; First_name function getRole1 () {$ user = $ this- & gt; Load user (accessed via Yii :: app () -> User-> ID); # Role role return $ role; # Rotor roll} // load user model Secure function loadUser ($ id = null) {if ($ this-> _model === faucet) {if ($ id! == null) $ this- & gt; _model = User :: model () - & gt; FindByPk ($ id); } $ $ -> Modell; }}? & Gt;

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
