Question

This is my code:

 function theme_freeway_dashboard_details($form) {

$pidobtained = $_GET['project_id'] ;

    $rows = array();
    foreach (element_children($form) as $key) {

            $row = array();                 
                $row[] = array('data' => drupal_render($form[$key]['FileID']));
                $row[] = array('data' => drupal_render($form[$key]['Filename']));
                $row[] = array('data' => drupal_render($form[$key]['SourceLanguageID']));
                $row[] = array('data' => drupal_render($form[$key]['TargetLanguageID']));
                $row[] = array('data' => l(drupal_render($form[$key]['StatusID']),'user/1/freewayRetrieve',array('query' => array('fileId'=> $row[0],'projectID'=> $pidobtained))));                            
                $row[] = array('data' => drupal_render($form[$key]['StatusDescription']));                      
                $rows[] = $row;


            }
            $header = array();
            $header[] = t('File ID');
            $header[] = t('File Name');
            $header[] = t('Source Language');
            $header[] = t('Target Language');
            $header[] = t('Status ID');
            $header[] = t('Status Description');


            //$output = theme('table', $header, $rows,array('size'=>10, 'class' => 'table_class'));
            $output = theme('table', $header, $rows);
            $output .= drupal_render($form);


        return $output;

    }

I am trying to pass paremeter on click on the link, the parameter being FileID. The URL being generated as a result of the above code is

   'http://localhost/drupalTheme/user/1/freewayRetrieve?fileId[data]=157960&projectID=437286' . 

Now when i try to get the values from this URL from the subsequesnt function using

   <?php
    $fileIdbtained = $_GET['fileId[data]'] ;
    $pidobtained = $_GET['projectID'] ;
    ?>

I am getting the value for projectID but not for fileID. Is this the correct way to go about accessing the parameters?
Would like to have your views.

Thanks

To be clear: In your foreach loop, $form[$key]['FileID'] is a FAPI element.

In other words: In every iteration of the loop, the variable $form[$key]['FileID'] (as well as $form[$key]['Filename'] and the others) is a PHP array which has a specific structure.

This “specific structure” is one that is expected by drupal_render() so that it knows how to “render” the element (that is, generate a string of HTML).

Now, for the case where you want to get the actual semantic value (i.e. 157960) of $form[$key]['FileID'] without the HTML, first you obviously have to stop passing it through drupal_render().

Then, since $form[$key]['FileID'] is an array (which happens to hold the structure of a FAPI element, as I mentioned previously) you need to access whichever of its elements holds the actual data you’re after. And according to your latest update, that element would be the one with a key of ‘#value’.

So, what you want to use is $form[$key]['FileID']['#value']. That is, the line of code that prepares that row, should be:

$row[] = array('data' => l(drupal_render($form[$key]['StatusID']),'user/1/freewayRetrieve',array('query' => array('fileId'=> $form[$key]['FileID']['#value'],'projectID'=> $pidobtained))));
