Re: Sessions & session_start() & my problem

that was a bit confusing, but it looks like you call session_start() more than once in a script. You only need to call it once, and you need to call it before any headers get sent, at the top of the script is a good place. If you're scripts are already setup like that just ignore me. Oh, also, if you include a file that has session_start() in it you'll get that warning too. -- -------------------------------------------------------------->> Jasper Howard :: Database Administration Velocity7 1.530.470.9292 http://www.Velocity7.com/ <<-------------------------------------------------------------- "Pahlevanzadeh Mohsen" <m_pahlevanzadeh@yahoo.com> wrote in message news:20040827212012.67593.qmail@web21424.mail.yahoo.com... > Dears,I have 3 files. > k.php : > <? > session_start(); > $S_userk=$HTTP_POST_VARS['u']; > $S_pass=$HTTP_POST_VARS['p']; > //echo $S_pass; > session_register('S_userk'); > session_register('S_passk'); > include 'http://1.1.1.1/membership/login.php?g=0'; > ?> > login.php: > define("HOST","localhost"); > define("USER","root"); > define("PASS"," "); > define("DB","mem"); > /////////////////////////////////////// > > session_start(); > if ($HTTP_GET_VARS['g']==1) > { > $username=$S_username; > $password=$S_password; > //print $username; > } > else if ($HTTP_GET_VARS['g']==0) > { > $password=$S_passk; > $username=$S_userk; > > } > > $S_username=$username; > $S_password=$password; > if(empty($S_username) && empty($S_password) ) > { > mysql_connect(HOST,USER) or die("connect"); > mysql_select_db(DB) or die("db"); > $result=mysql_query("SELECT count(*) as numfound > FROM usernames where user='$username' and > pass='$password'") or die("jjjjjjjgar"); > > > $result_ar=mysql_fetch_array($result); > if($result_ar['numfound'] < 1 ) > { > //echo "ffdsfsfsdvfdsfdssc"; > > //curl_exec(curl_init('http://1.1.1.1/membership/index.html')); > header('Location: index.html'); > exit; > } > > > session_register('S_username'); > session_register('S_password'); > echo "Logged in successfully!"; > > But when i loggin in my site,I recv following > warnings: > Warning: session_start(): Cannot send session cookie - > headers already sent by (output started at > /var/www/html/membership/k.php:2) in > /var/www/html/membership/k.php on line 3 > > Warning: session_start(): Cannot send session cache > limiter - headers already sent (output started at > /var/www/html/membership/k.php:2) in > /var/www/html/membership/k.php on line 3 > > > Please explaine me on my warnings..... > Yours,Mohsen. > > ===== > ---------DIGITAL SIGNATURE------------------- > ///Mohsen Pahlevanzadeh//////// > Network administrator & programmer > My work phone is : +98216054096-7 > My home phone is: +98213810146 > My emails is > m_pahlevanzadeh@yahoo.com > My website is: http://webnegar.net > ---------------------------------------------------------------- > > > > > __________________________________ > Do you Yahoo!? > New and Improved Yahoo!
