I’m looking to list results from a PHP page using jquery, which is updated every 3 seconds, but I’m not getting it. The code I’m using is:

<div id="listar"></div>

<script src="assets/js/jquery-3.1.1.min.js"></script>       

<script type="text/javascript">
function mostrar(){  
    $(document).ready(function(){       
             $.ajax({
                    type:'post',
                    dataType: 'json',
                    url: 'atualizar.php',
                    success: function(dados){
                    $('#listar').append(dados[0]);                         
                    }
            });
    });
}
//setInterval(function(){ mostrar; }, 3000);
setInterval(mostrar, 3000);
</script>

As an example, I put the PHP code below:

$ver = "teste";
echo json_decode($ver);

The problem is in Jquery and not in PHP ;)

    What is going wrong?

  • No PHP output shown.

  • I included in the post an excerpt that I forgot

    Do it inside the Success console.log(dados), and see if any results are coming...

    Would not be json_encode that you should be using?

    What is the status of the request, 200, 500? You only have the successful callback, put the error too, it may be having trouble parsing..

  • I really switched to json_encode and it worked. I’m sorry for the lack of attention and thank you all.

The type of response in the request ajax is asking for an object json, but the php code is doing the opposite: encoding a json for an object through the json_decode.

To correction was to exchange the method for json_encode.

$ver = "teste";
echo json_encode($ver); // codifica a variável para json e retorna via echo
