title: Ajax jquery Post didn't send parameters
body: <p>I use this code to send a post request to another page. post call works but no parameter send to that page :</p>
  
  <pre><code>$.ajax({ type: "POST", url: "insertar.php", data:"tipo_tar:1&amp;monto:" + "1000" + 
      "&amp;n_m:" + "100" + "&amp;refe:" + "100" 
      +"&amp;usuario:" + "pcisneros01" 
      + "&amp;email:" + "esadeghi@gmail.com" ,
      contentType:"application/x-www-form-urlencoded",
      success: function(result)
      {
          alert(result);
          if(result.indexOf("SMS")&gt;=0){
              $(".centro").hide();
              $(".content-area").hide();
              $("#bodythxRecarga").show();
          }
      }
  });
  </code></pre>
