include("database.class.php");
$tpcl=new database();
if(!empty($xx))
{
foreach($xx as $v)
{
$tpcl_result=$tpcl->Query("select numbers from tmxx where code=‘{$v[0]}‘");
$tpcl_result=$tpcl_result[0][0]+1;
$tpcl_result1=$tpcl->Query("update tmxx set numbers=$tpcl_result where code=‘{$v[0]}‘",1);
}
header("location:tp.php");
}
else
{
header("location:error.php");
