Good afternoon my doubt and the following I want to put a custom alert of the jquery confirm in the code in php but it does not run already I tried everything I already called the files and nothing if someone can help thanks

Here is my code, the section where I want to put jquery is inside an echo: 

echo"<script>alert('Nenhum Resultado Encontrado'), window.open('index.php','_self')</script>";

I tried to use it like this: 

                    echo"<script>$.alert({
    title: 'Alert!',
    content: 'Simple alert!',
    confirm: function(){
        alert('Confirmed!');
    }
});, window.open('index.php','_self')</script>";

Good afternoon,

Edited: From what I noticed you want to give an alert to the user that what he sought was not found. You must have a page like www.lovedevelopment.com.br/vusca.php?q=0 (q = 0 because you 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 one of the tips they gave you was using AJAX. Let's first go to the principles of using this "Disinfectant".

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

And when do I use this? I want to store my data in a mysql database and I have a file that inserts this into the bank an insert.php only the data is coming from a client-side form and I do not want to use PHP's POST.

Let's look at 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 the javascript. And when the result is null it returns what this file calls check_de_busca.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 sending an alert ( link ).

Thanks,

I am available
