PHP Voting System Redirect Not Working -

i'm attempting build simple php voting system website user asked vote on favorite photo. 1 vote permitted each day.

when vote cast php script will:

====

1 -- checks users ip address , compares ip log text file

2 -- if users ip address found in log checks see if last vote (for ip address) submitted on current date

3 -- if users ip address logged , last vote on current date user redirected page reminding them 1 vote allowed per day

4 -- if users ip address logged last vote prior current date, vote recorded , user redirected thank voting page

5 -- if user ip address not logged vote recorded , user redirected thank voting page.

====

unfortunately php script i'm working 1 of 2 things:

1 -- if "break" included after if/else statement ($logip == $ipaddress), script adds 2 votes , 2 ip entries log

2 -- if "break" removed, 1 vote entered , 1 ip address recorded. however, regardless of vote , ip being recorded, new voters , returning votes redirected page reminding them 1 vote permitted each day same user

the script follows:

====

// users vote, ip address , todays date $uservote = $_request['vote']; $ipaddress = $_server["remote_addr"]; $ipdate = date("y/m/d"); // if users vote null, redirect error page if ($uservote != "") {     $userfound = false;     $uservoted = false;     echo $userfound . " -- " . $uservoted . "<br /><br />";     $file_handle = fopen("ip_log.txt", "r");     // loop through file ip addrresses , dates addresses logged     while (!feof($file_handle)) {         $line_of_text = fgets($file_handle);         $parts = explode('||', $line_of_text);         $logip = $parts[0];         $logdate = $parts[1];         // check if logged ip address matches users ip address         if ($logip == $ipaddress) {             $userfound = true;             // check if logged vote date matches == today current ip address being checked             if ($logdate == $ipdate) {                 // ip address found , logged date == today, rredirect user try again later page                 header("location: http://www.fotohuis.ca/vote/tryagain.html");                 exit;             }             else {                 // ip address found logged date != today, keep checking until eof             }         }         else {             // ip address not found, keep checking until eof             continue;         }     }     // user found     if ($userfound == true) {         // user found logged vote date != today         if ($uservoted == false) {             // ip address log content             $filename1 = "ip_log.txt";             $content1 = file($filename1);             // insert user ip address log             $insertip = "\r\n" . $ipaddress .

any appreciated i've been @ week no progress :(

this code can simplified make easier understand , modify in future. there repeated code doesn't need be.

this untested should work , give idea on how move forward.

before try make sure test or backup existing vote counts!!!

<?php  $uservote = $_request['vote']; $ipaddress = $_server["remote_addr"]; $ipdate = date("y/m/d"); $iplogfile = 'ip_log.txt'; $resultlogfile = 'poll_result.txt';  //if users vote null or out of range, redirect error page if (empty($uservote) || $uservote < 0 || $uservote > 5) {     header('location: errorpage.html');     exit; }  $file_handle = fopen($iplogfile, "r");  //loop through file ip addrresses , dates addresses logged         while (!feof($file_handle) ) {     $line_of_text = fgets($file_handle);     $parts = explode('||', $line_of_text);     $logip = $parts[0];     $logdate = $parts[1];      if ($logip == $ipaddress && $logdate == $ipdate) {         // ip address found , logged date == today current ip         header("location: http://www.fotohuis.ca/vote/tryagain.html");         exit;     } } fclose($file_handle);  // user has not voted ever, or today  $insertip = "\r\n".$ipaddress."||".$ipdate; file_put_contents($iplogfile, $insertip, file_append);  //get poll result content $fp = fopen($resultlogfile, 'r+'); // open reading , writing flock($fp, lock_ex);  // lock file can't changed $content = fgets($fp); // read contents of file  //put vote content array $array = explode("||", $content); // $array[0] = picone; $array[1] = pictwo; etc  $array[$uservote] = (int)$array[$uservote] + 1;  ftruncate($fp); // truncate file empty rewind($fp); // jump beginning of file  $insertvote = implode('||', $array); // array string 0||1||2||3||4||5 fwrite($fp, $insertvote); // write new vote tally  flock($fp, lock_un); // unlock file fclose($fp); // close file  ///redirect user thank voting page header("location: http://www.fotohuis.ca/vote/thankyou.html"); exit; 

hope helps!
