i am currently working on a registration form project but i constantly bump into an error which i can't seem to figure out. The error consists of the registration button sending me to a 404 error page instead of doing the intended code. Can anyone spot any errors as i can't seem to find any. Please help.



    <?php 

session_start();



$_SESSION ['Error'] = '';



$mysqli = new mysqli ('ip', 'user', 'pass', 'dbname');

$_POST = filter_input_array(INPUT_POST);



           if ($_POST['username']) {

               $username = $_POST['username']; 

        }

        else {

            $_SESSION['Error'] = "Please enter your username";

        }







           if ($_POST['email']) {

               $email = $_POST['email']; 

        }

        else {

            $_SESSION['Error'] = "Please enter your username";

        }









           if ($_POST['password'] === $_POST['psw-repeat']) {

               $password = $_POST['password']; 

        }

        else {

            $_SESSION['Error'] = "Your passwords don't match";

        }  



        if ($_POST['captcha'] === $_SESSION['captcha']) { 

        }

        else {

            $_SESSION['Error'] = "Incorrect CAPTCHA";

        }



//        

            $sql = "INSERT INTO Users (User_name, Email, Password, Skills)"

            ."VALUES ('$username','$email','$password','$skills')";





    //if the query is successful, redirect to validation.php page



         if ($mysqli->query($sql) === true) {

             $_SESSION['Error'] = "Registration Succesful! Added $username to the database!";

             header("location: validation.php");



         }

         else {

             $_SESSION['Error'] = "User could not be added to the database!";

         }

    A 404 means that the page couldn't be found. Can you show the code/form where your registration button is? And maybe show/tell us about the structure of your files(file names and folders).

  • @DirkScholten the validation php and registration php are in the same source folder and this is the code for the button<button type="submit" class="signupbtn">Sign Up</button>

  • You may want to check the "action" of your form (the destination .php file from your origin .html file).

    Nov 19 '18 at 16:08










  • Well we need a bit more than just the button. You can edit your original post and add the whole <form> to it. That way we can see what page it tries to go to.

  • Well we need a bit more than just the button. You can edit your original post and add the whole <form> to it. That way we can see what page it tries to go to.

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
