Display component value

Well no.

When views is not enabled the tab was not shown on /admin/content. Was that intentional? After activating the admin_menu module I saw the admin/content/payments menu entry.

Adding

 'type' => MENU_LOCAL_TASK,

to $base in payment_menu() seems to do the trick.

But this is not really what I meant.
The payments on admin/content/payments have no relation to webform submissions, by them self they have little meaning (atleast when anonymous visitors use the form).

I guess this is a feature request then...

I would like to have some data in the webform submission to relate it to the payment.

Thanks, that works great.

I guess it needs another hook implementation for csv:

/**
 * Implements _webform_csv_headers_component().
 */
function _webform_csv_headers_payment_webform($component, $export_options) {
  $header = array();
  $header[0] = '';
  $header[1] = '';
  $header[2] = $component['name'];
  return $header;
}

/**
 * Implements _webform_csv_data_component().
 */
function _webform_csv_data_payment_webform($component, $export_options, $value) {
  if ($value[0]) {
    return $value[0]; // TODO I guess the paid amount would be appropriate.
  }
  else {
    return '';
  }
}

And hooks for the table and analyse pages:

/**
 * Implements _webform_analysis_component().
 */
function _webform_analysis_date($component, $sids = array()) {


/**
 * Implements _webform_table_component().
 */
function _webform_table_date($component, $value) {

CSV look OK.

What about this as a table hook.

Yes #8 looks OK, a link there is better.
