Hi

I have this following code, i'm using easyui-datagrid and when i choose "new" it open a form you can see in the end of the code but the echo returns nothing.

<?PHP
require_once("./include/membersite_config.php");
if(!$fgmembersite->CheckLogin())
{
    $fgmembersite->RedirectToURL("login.php");
    exit;
}

$userid = $fgmembersite->UserId();
?>

 <body>
      <div class="easyui-layout">
      <h2 class="sub_title">Bem vindo  <?= $fgmembersite->UserFullName(); ?> !</h2>

      </div>
   </body>
</html>

<input type="text" name='iduser' id='iduser' value="<?= echo $fgmembersite->UserId(); ?>">

The "echo" outside the form works, i have the userId, so what's wrong?

Thanks

You dont need to use echo within PHP's "echo" short tags (that is what the <?= tag means). You should note however if you are not using PHP5.4 then this type of PHP tag is not available unless you enable a setting called short_open_tag. For this reason I always use full PHP tags

<input type="text" name='iduser' id='iduser' value="<?php echo $fgmembersite->UserId(); ?>">

OR use the following as you have defined $userid line 9
<input type="text" name='iduser' id='iduser' value="<?php echo $userid; ?>">

Outside the form i have the variable working. Inside the form....is blank

I can populate the first

<div class="fitem">
               <label>Cargo:</label>
               <select name="cargo" id="cargo_name"></select>
            </div>

with JavaScript function

function populateCargo() { 
            $.getJSON('t.php', {cargo:$('#cargo').val()}, function(data) {
                var select = $('#cargo_name');
                var options = select.prop('options');
                $('option', select).remove();
                $.each(data, function(index, array) {
                    options[options.length] = new Option(array['cargo']);
                });
            });        
         }
         $(document).ready(function() {
         populateCargo();
         $('#cargo').change(function() {
         	populateCargo();
         });     
         });
