php - Warning: mysqli_real_query() expects exactly 2 parameters, 1 given (Register Page) [SOLVED] -

-

This error was encountered when I tried to create a registration page Warning: mysqli_real_query () Expecting precise 2 parameters, 1 tried to use mysql_query (), but then it says that it is old

this is index.php: 

   & Lt; Title & gt; Untitled Page & lt; / Title & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Form method = "POST" action = "reg.php" & gt; & Lt; Table & gt; & Lt; TR & gt; & Lt; TD & gt; Username: & lt; / TD & gt; & Lt; Td> & Lt; Input type = "text" name = "username" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; TD & gt; Email: & lt; / TD & gt; & Lt; Td> & Lt; Input type = "email" name = "email" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td> First name: & lt; / Td> & Lt; Td> & Lt; Input type = "text" name = "fname" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td> Last name: & lt; / Td> & Lt; Td> & Lt; Input type = "text" name = "lname" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; TD & gt; Password & lt; / TD & gt; & Lt; Td> & Lt; Input type = "password" name = "pass" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; TD & gt; & Amp; Nbsp & lt; / TD & gt; & Lt; Td> & Lt; Input type = "submit" name = "submit" value = "submit" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; / Table & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt;   
 This is my config.php:  
  & lt ;? Php $ link = mysqli_connect ('localhost', 'root', '', 'reg')? & Gt;   
 and my reg.php:  
  & lt; Php includes "config.php"; $ Username = $ _POST ['Username']; $ Email = $ _POST ['email']; $ Fname = $ _POST ['fname']; $ Lname = $ _POST ['lname']; $ Password = MD5 ($ _ POST ['pass']); $ Insert = 'INSERT users (Username, Email, FNL, Lanna, Pass) VALUES ("'. $ Username '' ',' '. $ Email' ',' '. $ Fname.' ',' '' $ Lname. '', ''. $ Password. ''; Mysqli_real_query ($ insert);? & Gt;   
 reg.php I think the problem is the cause. / P>  
 
 
 As an error, you have the  mysqli_real_query  function this criterion is your mysqli $ link .

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...
