I wonder whether someone could help me please.

I’m capturing a Session variable within a HTML form as follows:

$lid = $_SESSION['lid'];

From this main HTML form, using the following lines of code, I then load an external ajax table using the ‘mysqlajaxtableeditor` software:

</script> 
 <!-- Set ajax url -->
        <script type="text/javascript">
            trackHistory = false;
            var ajaxUrl = 'Example3.php';
        </script>

<body id="page2" onload="toAjaxTableEditor('update_html','');">

What I’d like to be able to do, is capture the Session variable from the main form and pass it to the external ajax table.

I’ve read a number of posts on this site which I hoped I would be able to solve my problem from, but I just can’t seem to pass the value across.

From what I’ve read, I’ve tried the following on my main form :
var ajaxUrl = 'Example3.php?lid=$lid';, then in the receiving AJAX table script, $lid = $_GET['lid']; but it doesn’t work and i’m not sure where I’m going wrong.

For additional information, I’ve posted the AJAX table code below:

class Example1 extends Common
{
    function initiateEditor()
   {
      $tableColumns['findid'] = array('display_text' => 'Find ID', 'perms' => 'TV');
      $tableColumns['dateoftrip'] = array('display_text' => 'Date of Trip', 'perms' => 'ETV');
      $tableColumns['finddescription'] = array('display_text' => 'Find Description', 'perms' => 'ETV');
      $tableColumns['detectorname'] = array('display_text' => 'Detector Used', 'perms' => 'EVT');
      $tableColumns['searchheadname'] = array('display_text' => 'Search Head Used', 'perms' => 'ETV');
      $tableColumns['pasref'] = array('display_text' => 'PAS Ref.', 'perms' => 'ETV');

      $tableName = 'finds';
      $primaryCol = 'findid';
      $errorFun = array(&$this,'logError');
      $permissions = 'EID';

      require_once('php/AjaxTableEditor.php');
      $this->Editor = new AjaxTableEditor($tableName,$primaryCol,$errorFun,$permissions,$tableColumns);
      $this->Editor->setConfig('tableInfo','cellpadding="1" width="800" class="mateTable"');
      $this->Editor->setConfig('tableTitle','');
      $this->Editor->setConfig('orderByColumn','dateoftrip');
      $this->Editor->setConfig('editRowTitle','Edit Details');
      $this->Editor->setConfig('iconTitle','Edit Find Details');
   }


   function Example1()
   {
      if(isset($_POST['json']))
      {
         session_start();
         $this->mysqlConnect();
         if(ini_get('magic_quotes_gpc'))
         {
            $_POST['json'] = stripslashes($_POST['json']);
         }
         if(function_exists('json_decode'))
         {
            $data = json_decode($_POST['json']);
         }
         else
         {
            require_once('php/JSON.php');
            $js = new Services_JSON();
            $data = $js->decode($_POST['json']);
         }
         if(empty($data->info) && strlen(trim($data->info)) == 0)
         {
            $data->info = '';
         }
         $this->initiateEditor();
         $this->Editor->main($data->action,$data->info);
         if(function_exists('json_encode'))
         {
            echo json_encode($this->Editor->retArr);
         }
         else
         {
            echo $js->encode($this->Editor->retArr);
         }

      }
   }
}
$lte = new Example1();
?>

I just wondered whether someone could possibly look at this please and let me knwo where I’m going wrong?

Many thanks and kind regards

    After a lot of work and searching the Internet, I found the solution.

    In the HMTL page I wrote this:

     <!-- Set ajax url -->
        <script type="text/javascript">
            trackHistory = false;
            var ajaxUrl = 'ajaxtable.php?lid=$lid';
        </script>
<body id="page2" onload="toAjaxTableEditor('update_html','');">

    In my receiving AJAX Table Editor software script I wrote:

    function initiateEditor()
{
    $tableColumns['locationid'] = array('display_text' => '', 'perms' => '','data_filters' => array('filters' => array("='".$_SESSION['lid']."'")), 'default' => $_SESSION['lid']);

    I hope this helps someone in the future.

    Kind regards
