Cant make JSON/PHP echo message appear using jQuery -

-

i'm trying make php echo messages show whenever users inputs either nothing @ or no numbers. ive been able make error messages show when doesnt input numbers onto text field.

however cant make error message i've created in php show whenever clicks send button without inputing @ in text field.

my php code:

$resurs    = array(); $fyll = $_get['inputfield']; $dg = 2;  $nummer1      = $nummer1 * $dg; $fel = "fill in number"; $nummer2      = $nummer1 * $fill; $no = "field empty";  if (is_numeric($fyll)){  $resurs = array(     "nummer1" => $nummer1. "<br>",     "nummer2" => $nummer2. "<br>"  );  echo json_encode($resurs);      }  else {     $resurs = array (     "fel" => $fel. "<br>"     );  echo json_encode ($resurs); }            if (empty($fyll)){     $resurs = array (     "no" => $no. "<br>"     );      echo json_encode ($resurs); }

my jquery:

$(document).ready(function(){     $("#submit1").click(function(){     var siffra = document.getelementbyid("inputfield");         $.getjson("form.php?inputfield="+siffra.value, function(result){ var t1; var t2; var t3; var error;                      $.each(result, function(i, field){                  if (i =="nummer1"){                 t1 = field                 }                  if (i == "nummer2"){                 t2 = field                 }                  if (i == "no"){                 t3 = field                 }                  if (i == "fel"){                 error = field                 }                                $(".d1").html(t1);                 $(".d2").html(t2);                 $(".d3").html(t3);                 $(".d3").html(error);             });          });     }); });

field object. need retrieve properties of object. either, field.nummer1, field.nummer2, field.fel or field.no depending on response request. try this:

$.each(result, function (i, field) {     if (i == "nummer1")         t1 = field.nummer1;      if (i == "nummer2")         t2 = field.nummer2;      if (i == "no")         t3 = field.no;      if (i == "fel")         error = field.fel;      $(".d1").html(t1);     $(".d2").html(t2);     $(".d3").html(t3);     $(".d3").html(error); });

note you're setting value of each .dx element in each iteration of loop, when there no value variable provided. suggest check logic of function against requirements.
