I have the following structure in php:

            <?php
            // Verifica se cancela o cadastro
            if ((!empty($action)) and ($action == "cancelar")) {

                ?>
                <script>
                    confirm ('Tem certeza que quer cancelar?>');
                </script>
                <?php
                die;

                // Aqui executa as operaçøes no BD
            }
        ?>

Well I need to make php process the user information only if the user confirms the alert.

Can you do this using jQuery?

Just because JS is "inside" PHP does not mean that confirm() will prevent the execution of PHP, so in general, when displaying confirm() , PHP has already finished executing.

/ p>

Another detail is that confirm() how documentation shows returns true or false so you need to check the response with a if .

Without more details complicates to give a better example and the correct one would be something like this:

document.addEventListener("DOMContentLoaded", function(event) {
  var btCancela = document.getElementById('cancelar');
  btCancela.addEventListener('click', function(e){
    if( confirm('Deseja realmente cancelar?') ){
      //aqui é o pulo do gato, você precisar fazer uma requisição ajax ou redirecionar para uma outra URL, ou seja la como você apaga o registro do banco.
      console.log('usuario confirmou o cancelamento');
    }
  });
});

<button id="cancelar">CANCELAR</a>

Javascript and PHP are different languages for different purposes, unfortunately they do not communicate the way you imagined.

You can do this right on the cancel link:

<a title="Cancelar" onclick="return confirm('Você tem certeza?');" href="seuscript.php?ation=cancelar&id=XX">Cancelar</a>

But if you really want to do with php follow an example:

<?php

    $action = $_GET['action'];
    // Verifica se cancela o cadastro
    if ((!empty($action)) and ($action == "cancelar")) {  ?>
        <a title="Cancelar" href="seuscript.php?action=cancelar-confirmado&id=XX">VocÊ tem certeza que deseja cancelar?</a>
    <?php
    }elseif ((!empty($action)) and ($action == "cancelar-confirmado")){
        # seu codigo de cancelamento aqui
        echo "Cancelado com sucesso!!";
    }

?>
