Simple PHP Login System: Registration Error ( Notice: Only variables should be passed by reference )

[StephenMBassett]

I had a difficult time solving this bug, and finally solved it.  I'm posting it here to help others who might be struggling with the same situation. 

Code Source:

This code is from the Simple PHP Login System, Lesson 17 & 18.  

My Setup:

• Machine: Windows 10
• WAMP
• PHP version: 7.4.9
• Code Editor: VS Code

Here is my error notice:

Notice: Only variables should be passed by reference in C:\wamp64\www\phplogin-parts17-18-projectfiles\register.php on line 144

I got that error message when I tried to register a member.

The problem lies in LINE 144

SOLUTION:

 You need to create a new variable that represents...

 

      md5($input['pass'] . $config['salt'])

 

 Let's call that variable $salty....

 

      $salty = md5($input['pass'] . $config['salt']);

 

...and then insert that new variable $salty into ... $stmt->bind_param(x, x, x, x, $salty);

 

The code should look like this:

 

     if ($stmt = $mysqli->prepare("INSERT members (username, email, type, password) VALUES (?,?,?,?)"))

     {

         $salty = md5($input['pass'] . $config['salt']);

         $stmt->bind_param("ssss", $input['user'], $input['email'], $input['type'], $salty);

         $stmt->execute();

         $stmt->close();

 

 

 

 

 

 

 

Hope that helps!
