Good afternoon,

Edited: From what I understand you want to give an alert to the user that what he searched for was not found. You should have a page like www.lovedevelopment.com.br/vusca.php? q=0 ( q=0 and did not find the result ). In this case we will see how it would look in php.

<?php 
   //Analisando o caso com a URL ww.lovedevelopment.com.br/vusca.php?q=0
   //vamos primeiro colocar em uma variável o resultado
   $testa_minha_busca = $_GET['q'];
    //Depois vamos testar se o resultado veio igual a 0
   if ( $testa_minha_busca == 0 ) {
       //Se for encontrado vamos mandar um alerta 
       echo "<script>alert('Sua busca tá osso man!');</script>";
       // Em seguida vamos mandar ele para home e 3 segundos
       header( "refresh:3;url=home.php" ); 
}
?>

I saw that one of the tips they gave you was to use AJAX. Let’s first start using this "Disinfectant".

What is it ? Method that opens a window to pass client-side information to the server-side.

And when do I wear this ? I want to save my data in a mysql database and I have a file that inserts it into the database an Insert.php only that the data is coming from a client-side form and I don’t want to use the PHP POST.

Let’s take an example in a search. I have a file that calls check_de_busca.php and I want but I want the search to be dynamic and without Reload, and the data comes from javascript. And when the result is null it returns this file calls check_de_search.php.

  <script>
  $(document).ready(function() {
      //Quando clicar na busca
    $('botao_buca').click(function() {
        //chama o AJAX
      $.ajax({
          //vamos postar
        type: "post",
        //Para o Arquivo abaixo
        url: "check_de_busca.php",
        //A variável do javascript que eu quero passar para o PHP é termo de busca
        data: "busca"+termo_de_busca,
        //Asynchrono
        async: true,
        //Se ele der sucesso da requisição e for 0 avisa os truta
        success: function(result) {
          if (result == 0) {
            alert('Sua busca tá osso man!');
          }
        },
      });
    });
  });
</script>

Just adjust your variables and Divs. And an additional interface tip if you’re going to send an alert ( http://t4t5.github.io/sweetalert/ ).

Thank you,
