i dont know why my code doesn;t check the id number and phone availability. it doesn;t insert data if phone or id number exits but it still goes to next.pl it insert data very well if phone or id number not exits. but i want to remain on same page if phone or id number exits and print error


if ($PHONE, $ID_NUMBER) {                               
$CHECK_PHONE = $DBH->prepare("SELECT COUNT(*) FROM tbl1 WHERE PHONE = 
+?");
$CHECK_PHONE->execute($PHONE);
$P = $CHECK_PHONE->fetchrow_arrayref();

$CHECK_ID_NUMBER = $DBH->prepare("SELECT COUNT(*) FROM tbl1 WHERE ID_N
+UMBER = ?");
$CHECK_ID_NUMBER->execute($ID_NUMBER);
$ID = $CHECK_ID_NUMBER->fetchrow_arrayref();


if ($P eq $PHONE) {
   $error_phone = "phone exits";
}
   if ($P eq $PHONE) {
   $error_id = "id exits";
 } 
   
 
if ($P ne $PHONE && $ID ne $ID_NUMBER){ 
$ADD_DATA = $DBH->prepare('INSERT INTO tb11(PHONE, ID_NUMBER)
                          VALUES(?,?)');
                          $ADD_DATA->execute($PHONE, $ID_NUMBER);
                          $ADD_DATA->finish;

# go to next.pl next page 
                          
                          
} 
  }
