[SOLVED] Help session problem & header

[supermerc]

This is the error im getting

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/xgame/public_html/random/edit_profile.php:1) in /home/xgame/public_html/random/edit_profile.php on line 2
You must be logged in to edit your profile.

And this is my code

[code]<?php
      session_start();
  ob_start();
      require("config.php");
      require("func.php");
      //echo some styles to spice it up...
      echo "
      <style>
      body
      {
      background: #131313;
      font-family: Verdana, Arial;
      font-weight: bold;
      font-size: 9px;
      color: #FFFFFF;
      }
      .register_box
      {
      border: 1px solid #323232;
      background: #202020;
      font-family: Verdana, Arial;
      font-weight: bold;
      font-size: 9px;
      color: #FFFFFF;
      }
      </style>
      ";
      if(isset($_SESSION['logged_in']))
      {
      $session_username = $_SESSION['username'];
      // further checking...
      if(username_exists($session_username))
      {
      $get_info = mysql_query("SELECT email FROM users WHERE username = '$session_username' LIMIT 1");
      if(mysql_num_rows($get_info) > 0)
      {
      $user_info = mysql_fetch_assoc($get_info);
      if(!isset($_POST['do_edit']))
      {
      echo '
      <form action="edit_profile.php" method="post">
      <input type="text" name="email" value="' . $user_info['email'] . '" />
      <br />
      <input type="submit" name="do_edit" value="Edit Your Profile" />
      </form>
      ';
      }
      elseif(isset($_POST['do_edit']))
      {
      $email = mysql_real_escape_string($_POST['email']);
      // assign all errors to an array
      $errors = array();
      if(empty($email))
      {
      $errors[] = 'Your email was empty.';
      }
      if(!is_valid_email($email))
      {
      $errors[] = 'Your email was not in a valid email format.';
      }
      // if array elements is greater than 0,
      // then we KNOW there was an error
    // else, no error, move on to processing
      if(count($errors) > 0)
      {
      echo '<b>ERRORS:</b><br />';
      foreach($errors as $err)
      {
      echo $err . '<br />';
      }
      }
      else
      {
      // everything is ok, update the DB
      mysql_query("UPDATE users SET email = '$email' WHERE username = '$session_username'");
      echo 'Profile Edited.';
      }
      }
      }
      else
      {
      echo 'Could not find profile info for your username.';
      }
      }
      else
      {
      echo 'Sorry, your session username doesnt exist.';
      }
      }
      else
      {
      echo 'You must be logged in to edit your profile.';
      }
  ob_end_flush();
      ?>[/code]

I added

ob_start(); at the beggening and ob_end_flush(); Because i read that it could solve the problem but it didnt.

Do you have any HTML code preceding the "<?php"?

[supermerc]

No thats my whole code

[ted_chou12]

sorry to ask a stupid question, but what is the session_start() at the top for, do you really need it? try deleting it and entering the page.

[supermerc]

no you need that because its a page to edit your profile you need to be logged in for that

[ted_chou12]

have you got other user pages (simple) ones that do work? or is this your user login page? if yes, try making another user page which is simple ie. just texts, no text area input fields forms and stuff.

as ken said - check for code before the < ?php, even if you cant see anything. go DIRECTLY to the left of the very first < and press backspace a couple of times, save it, and try again.

the sticky at the top of the php help forum (header/session errors) will explain several causes and solutions, but 9/10 in this case, it's due to something being output to the browser before your 'session_start'.

cheers

[supermerc]

ya but like i said, theres NOTHING at all no space or anything before, thats it.

[kenrbnsn]

Sometimes there are unprintable characters there that have been known to cause problems. Try deleting that line and re-typing it.

Are you including this file from another file?

[supermerc]

There was 1 space actually that i missed, now the error is gone but i still have an error saying that im not logged in.

Please check it out yourself.

Just use supermerc as username and ilmilm as password unless you want to register.

Click My profile to see what im trying to do.
