@ rubberman, creating new table each day is not possible, because the users can book the ticket until 9 am. Also daily booking report will get generated at this time.

@pty, I can't use auto increment for BARCODE_SLNO because it should start from 1 on each day.

I'm trying to generate barcode tickets after successful booking and it's working fine. But yesterday (08-Jan-2017) night at 11.59 pm, one customer booked 2 tickets but the ticket sl.no was duplicate. Tthat is both tickets sl.no was 1. Actually it should be 2. But the next customer's tickets sl.no was correct, it's 3,4,5. Is there any mistake in the code below where the tickets get generated?

for($j=1;$j<=$cat_array[$i];$j++) {
  $sel_max_dt =  mysql_query("select MAX(DT) AS maxdt, MAX(REC_NO) AS maxrec FROM  tkt_barcode");
  //to select max date and max rec no.
  $row_max_dt = mysql_fetch_array($sel_max_dt);
  $dt_max = $row_max_dt['maxdt'];
  //$no_max = $row_max_dt['maxno'];
  $recno = $row_max_dt['maxrec'];
  if($dt_max ==  date("Y-m-d") && $recno == $TxnID) {
    //if same date and same bkid  barcode slno continues.
    $sel_no = mysql_query("select MAX(BARCODE_SLNO) AS maxno FROM  tkt_barcode WHERE REC_NO=".$TxnID);
    $row_sel_no = mysql_fetch_array($sel_no);   
    $tkt_slno = $row_sel_no['maxno'];
    $tkt_slno = $tkt_slno + 1;
  }
  if($dt_max ==  date("Y-m-d")&& $recno != $TxnID) {
    //if same date and different bkid  barcode slno continues.
    $sel_no = mysql_query("select MAX(BARCODE_SLNO) AS maxno FROM  tkt_barcode WHERE DT='$dt_max' ");
    $row_sel_no = mysql_fetch_array($sel_no);   
    $tkt_slno = $row_sel_no['maxno'];
    $tkt_slno = $tkt_slno + 1;
  }
  if($dt_max != date("Y-m-d") && $recno != $TxnID) {
    //if not same date start barcode slno from 1.
    $tkt_slno = 1;
  }
  $sel_sl_no = mysql_query("select MAX(SL_NO) AS slno FROM  tkt_barcode WHERE REC_NO=".$TxnID);
  $row_slno = mysql_fetch_array($sel_sl_no);
  $slno = $row_slno['slno'];
  $bartkt_slno = $slno + 1;
  if($i==1 && $j>$count_promo_adult && $arr_edit["PROMO_CODE"]!=""){
    //adult cat and total adult count > total promo adult count
    $disc_adult = $adult_amt;
    $discamt=$adult_amt - $disc_adult ; //  discount amt
    $rate=$adult_amt;  //normal rate
    $net_amt=$disc_adult; //discount ...
