Aero77 Posted May 9, 2014 Share Posted May 9, 2014 I have this code, but I'm getting headers allready sent erros cause of the setcookie part. How can I fix this ? Errors: string(0) "" Warning: Cannot modify header information - headers already sent by (output started at /home/xxxxxxxx/public_html/index.php:27) in /home/xxxxxxxx/public_html/index.php on line 124 case "3": echo " <h2 align=\"center\">Arbeidstid - Start/Stop</h2>"; $today = date("d-m-y"); $time = date("H:i"); $userid = $_COOKIE['userid']; echo "<form action=\"index.php?fid=3\" method=\"post\">"; if (isset($_POST['today'])) { $dhours = $_POST['dhours']; $output = str_replace(',', '.', $dhours); var_dump($output); $dhours = ceil($output); if (isset($_COOKIE['wstart'])) { $query=$oDB->Prepare("UPDATE workhours SET stop=:time, dhours=:dhours WHERE userid=:userid ORDER BY start DESC LIMIT 1"); $query->execute(array(':userid' => $userid, ':time' => $time, ':dhours' => $dhours)); unset($_COOKIE['wstart']); setcookie("wstart", "", time()-3600); } else { $query=$oDB->Prepare("INSERT INTO workhours (userid, date, start) VALUES (:userid, :today, :time)"); $query->execute(array(':userid' => $userid, ':today' => $today, ':time' => $time)); setcookie("wstart", $today, time()+96000); } echo "<p class=\"red\">Ny data er lagret! <a href=\"user.php\">[Klikk her for å komme til ditt brukerpanel].</a></p>"; if (!$query) { echo "\nPDO::errorInfo():\n"; print_r($oDB->errorInfo()); } } elseif (!isset($_POST['today'])) { if (isset($_COOKIE['wstart'])) { echo "<input type=\"hidden\" name=\"today\" value=\"$today\"><input type=\"text\" name=\"dhours\" placeholder=\"antall timer kjørt\" required /><input type=\"submit\" value=\"stop\" />"; } else { echo "<input type=\"hidden\" name=\"today\" value=\"$today\"><input type=\"submit\" value=\"start\" />"; } } else { echo "yeah yeah";} echo "</form>"; break; Thanks for reading.

Jacques1 Posted May 9, 2014 Share Posted May 9, 2014 The manual will help. Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including <html> and <head> tags as well as any whitespace. You cannot have output before setting a cookie. Since you have plenty of output before you finally call setcookie(), you need to restructure your application. It's generally poor practice to heavily mix PHP and HTML (also known as “spaghetti code”). Put the application logic on top of the script and echo the output at the very end of the script. This will prevent problems like this in the future.
