ok, i found the solution :
in file ot_total.php the function :
function process() {
global $order, $currencies;
$this->output[] = array('title' => $this->title . ':',
'text' => '<b><input type="text" style="text-align: right; border:none; background:none;" name="total__" value="' . $currencies->format($order->info['total'], true, $order->info['currency'], $order->info['currency_value']) . '"></b>',
'value' => $order->info['total']);
}
have been changed !! (an input type have been added !!!) but no comment to know why ?, who ? and when ?!
so i check the original file in the package of oscommerce and i turned it back to original version :
original :
function process() {
global $order, $currencies;
$this->output[] = array('title' => $this->title . ':',
'text' => '<b>' . $currencies->format($order->info['total'], true, $order->info['currency'], $order->info['currency_value']) . '</b>',
'value' => $order->info['total']);
}
and it work fine ! :-"
