$. post return 2 values

Question

I have following code:

 <script>

    $.post('http://localhost/app/user.php', {acao: acao}, function(retorna){ 

     $("#demo").html(retorna);

     if(retorna == "sucesso") {faça x}

    });

 </script>

But in the user.php he returns several echo dentros of conditions if. So if I have in PHP, for example, echo "sucesso"; and another echo "sucesso"; he returns success.

I would like to know how I do to catch each of that return separately?

Answer 1

To redeem each information of this return, use the function json_encode and return only one echo for your Javascript.

Example:

$resposta['status'] = 'success';
$resposta['line'] = 1;

echo json_encode($resposta);

After the execution of that echo has a format JSON:

{"status":"success","line":1}

On the return of your javascript do:

jQuery.post()

 <script>

    $.post('http://localhost/app/user.php', {acao: acao}, 
    function(retorna)
    { 

        if (retorna.status == 'success')
        {
           //faça alguma coisa 
        }

        if (retorna.line == 1)
        {
            //faça mais alguma coisa
        }
    },'json');

 </script>

That is, returns a data(s) in format JSON, so that your Javascript, work with the return information. Also can be received a information list.
