I want to put an alert after sending the form to the database, with something like "Your message has been sent." [closed]

I wanted when the form was sent to the Bank, an alert would appear with something like "It was right to insert" if it did not say "Error sending your message". 

<?php 

    if(!empty($_FILES['uploaded_file'])){
        $username = 'root';
        $password = '';
        $connection = new PDO( 'mysql:host=localhost;dbname=bd', $username );

        $query = "INSERT INTO denuncia (descricao, imagem, id_usuario, oque_descricao,id_bloco, id_denuncia_oque) 
              VALUES (:descricao, :imagem, :id_usuario, :oque_descricao, :id_bloco, :id_denuncia_oque)";

        $statement = $connection->prepare($query);





        $path = "img_denuncia/";
        $path = $path . basename( $_FILES['uploaded_file']['name']);
        if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path))



        $valores = array();
        $valores[':descricao'] = $_POST['descricao_denuncia'];
        $valores[':imagem'] = $_FILES['uploaded_file']['name'];
        $valores[':id_usuario'] = 2;
        $valores[':oque_descricao'] = $_POST['oque_descricao'];
        $valores[':id_bloco'] = $_POST['bloco_denuncia'];
        $valores[':id_denuncia_oque'] = $_POST['id_denuncia_oque'];



        $result = $statement->execute($valores);


    }
    ?>

Here is the Form 

<form id="caixa" class="center-block row col-xl-6" enctype="multipart/form-data" name="formulario"  method="POST" action="">
            <br>
              <div class="row p-0 no-margin col-12 col-sm-12  col-md-12 col-lg-10 col-xl-12" >

Or you do as @Reignomo said, or you make a return to a page passing through parameter via get a type number 

if(deucertonophp){
  header('Location: http://www.home.php?msg=1');
}else{
  header('Location: http://www.home.php?msg=2');
}

and then in the home you leave a php code like this 

if(isset($_GET['msg'])){
   if($_GET['msg'] == 1){
     echo "Deu certo! parabens";
   }
   elseif($_GET['msg'] == 2){
     echo "Deu errado! tente de novo";
   }
}

Besides these echo, you can assign the $ _GET value to a php variable, and work with it in a modal eg.

You can do this with AJAX as follows; 

if( $result = $statement->execute($valores))
{
 echo 1; // dados enviados com sucesso
}
else
{
// na verdade o else não é necessário mas se preferir pode colocar
 echo 0; // erro ao tentar enviar dados 
}

The php page you're in forms an ajax to display the alert, something like; 

$('#form').submit(function() {
        $.ajax({ 
            data: $(this).serialize(), 
            type: $(this).attr('method'),
            url:"PAGINA PHP COM QUE ENVIA OS DADOS",
            success: function(retorno) {
                   if(retorno==1)
                  {
                    alert("Formulário enviado com seucesso");
                  }
                   else
                  {
                    alert("erro ao enviar formulário");
                  }
            }
        });
        return false; 
    });
