Successful php registration response

Question

I’m trying to make a return "Registration made successfully" but always falls in Else, he is not counting the number of lines.

public function adicionarAluno(string $nome, string $matricula, string $endereco, string $tel): void{

        $adicionar=$this->mysql->prepare("INSERT INTO aluno (nome,matricula,endereco,tel) VALUES (?,?,?,?);");
        $adicionar->bind_param('ssss',$nome,$matricula,$endereco,$tel);
        $adicionar->execute();
        $teste=$adicionar->num_rows;
        if($teste > 0){
            echo "<script>alert('Cadastro realizado com sucesso!');</script>";
        }else{
            echo "<script>alert('Falha!');</script>";
        }


    }

Answer 1

The registration is being carried out? Or it goes straight to LSE without registering?

Have you adapted this function from any other language? It’s just that I don’t remember having to use variable type declaration (string) in php, and I never did any function that used "void".

Try to leave it like this and see if it works, if it doesn’t work it returns here and leave the code of your connection file:

public function adicionarAluno($nome, $matricula, $endereco, $tel){

    $adicionar=$this->mysql->prepare("INSERT INTO aluno (nome,matricula,endereco,tel) VALUES (?,?,?,?);");
    $adicionar->bind_param('ssss',$nome,$matricula,$endereco,$tel);
    $adicionar->execute();
    $teste=$adicionar->num_rows;
    if($teste > 0){
        echo "<script>alert('Cadastro realizado com sucesso!');</script>";
    }else{
        echo "<script>alert('Falha!');</script>";
    }
