Multiple for Submission or Issue with Insert Query?

Hi All,

i have a weird issue, i have a form that a user submits with a card number, my script does some checking and ultimately submits a transaction to the database.

recently, it has been running the insert query multiple times and i cant figure out why.

At first i thought it was form submitting more than once but I have all my error or success for the form redirecting back to the page with

 return redirect::to('/transactions/create');

so as not to submit another post request.

This is my inster query:

DB::beginTransaction();
                  
                    try
                    
                    
                          {
                              
                              $tdata['ClientID'] = $check_client[0]->ClientID;
                              $tdata['Swipe_Card_Key'] = $select_client[0]->Swipe_Card_Key;
                              $tdata['Timestamp'] =     now();   
                              $insert_transaction_data = DB::table('Client_Transactions')->insert($tdata);
                                               
                            
                              if($insert_transaction_data) {
                                DB::commit();

                                                } catch (\Exception $e) {
                                                      Log::error($e->getMessage());
                                                      
                                                  }
                                              }

Any ideas why this could be happening? THe timestamps on insterted data are all within 1 milliesecond
