Tylor_Famous Posted January 29, 2008 Share Posted January 29, 2008 Hello, I am working on a login form and am having trouble. I am getting the following error: Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/lin/index.php:13) in /link/myfile.php on line 3 I don't quite get this because on line three is nothing more than session_start(); I saw some one say that the error was from spaces before the <?php tag but I have NO spaces… Also, thought I would just let you know, this code is going to be the menu bar for a site of mine so I don't have opening (or closing) <html> tags because I am going to include it into the site with php. And , as you can probably see by my coding, I am new to php and mysql so a simple explanation with small words is appreciated Here is the entire code (a little bit still in the works). I hope you can help me find my answer. Thanks! <?php session_start(); include("db.php"); loginInfo(); $table = 'login'; $whattodo = "notloggedin"; if($_SESSION['session_var'] == "skiplogin"){ $textbox = "You are now logged in!<br> Would you like to <form action=\" $PHP_SELF \" method=\"post\" name=\"logout\"> <input type=\"hidden\" name=\"$whattodo\" value=\"logout\" /> <input name=\"logout\" type=\"submit\" value=\"Logout\" /> </form> "; ///////////////// Relogin \\\\\\\\\\\\\\\\\\\\\\\ } else if ( $whattodo == "relogin" ){ mysql_pconnect($host, $user, $pass); mysql_select_db($database); $reloginname = $_POST["username"]; $reloginpass = $_POST["password"]; $query = "SELECT password FROM $table WHERE username = '$reloginname' "; $result = mysql_query($query); $row = mysql_fetch_array($result); if($reloginpass == $row['password']){ $textbox = "You are now logged in!"; $_SESSION['session_var'] = "skipLogin"; } else { $textbox="sorry something is wrong"; session_destroy(); } } else if ($whattodo == "notloggedin"){ $textbox = " <form action=\" $PHP_SELF \" method=\"post\" name=\"loginform\"> <ul> <li>Username:</li> <li><input name=\"username\" type=\"text\" maxlength=\"20\"></li> <li>Passoword:</li> <li><input name=\"password\" type=\"password\" maxlength=\"20\"></li> <li><input name=\"Login\" type=\"submit\" value=\"Login\"></li> <li>Don't have an account? <a href=\"#\">sign up</a>!</li> <input type=\"hidden\" name=\"$whattodo\" value=\"relogin\"> </ul> </form>"; } else if ($whattodo =="logout"){ session_destroy(); $whattodo = "notloggedin"; } ?> <div id="menubox1"> <h3>Account Information:</h3> <?php echo "$textbox" ?> </div> <div id="menubox2"> <h3>Navigation:</h3> <ul> <li><a href="#">Home Page</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> </ul> </div> <div id="menubox3"> <h3>Navigation:</h3> <ul> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> </ul> </div> <div id="menubox4"> <h3>Navigation:</h3> <ul> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> <li><a href="#">Link will go here</a></li> </ul> </div> Quote Link to comment Share on other sites More sharing options...
wildteen88 Posted January 29, 2008 Share Posted January 29, 2008 I presume the above code gets included in index.php file? If so the reason you are getting the error is because index.php is outputting some form of data (be it text/html/whitespace) on/around line 13. I would recommend you to remove session_start() function from the above code and place it at the top of parent file (index.php) instead. You do need to add session_start() to files which get included. Included files don't get parsed separately. Quote Link to comment Share on other sites More sharing options...
