session include file

[kenny873]

hi, i am going to write a session check include file to put it into pages that needed to be in logon mode. Therefore, I need to have an include file to check if the user is already logon.

how do i write this include file using session?

:roll:

at the top of each page you want to protect have something like

require_once("my_functions.php");

-in my_functions.php, include the code for your session check function

thanks philosophia,

but i need to know how to write the include file, not how to include the file...thanks anyway

[philosophia]

here's an example of a function to check to see whether or not the user is authenticated

function check_valid_user()

// see if somebody is logged in and notify them if not

{

  global $valid_user;

  if (session_is_registered("valid_user"))

  {



  if (!($conn = db_connect()))

return false;

  $result = mysql_query( "select *

                      from admin_user

                      where username = '$valid_user'");

					  $row = mysql_fetch_array($result);

					  echo "<font face='verdana,arial' size='2'>";
					  echo "<table width=\"100%\" border=\"0\" bordercolor=\"#ffffff\" bgcolor=\"#ffffff\" cellpadding=\"0\" cellspacing=\"1\" ><TR>
					  <td bgcolor=\"ffffff\"><br><font size=\"2\"><font face='verdana,arial' size='2'>";

					  echo "Logged in as:&nbsp;<b>".$row['firstname']."&nbsp;".$row['lastname']."</b>";      

					  echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<b>";


					  echo "</b></font>";
					  echo "</td><td bgcolor=\"ffffff\"><br><div align='right'><b>Current Time:</b>&nbsp;";
					  echo date("F j, Y, g:i a");
					  echo "</div></td></TR></table>";

  if (!$result)

return false; 



 }

  else

  {

 // they are not logged in 

 do_html_heading("Problem");


  echo "<font face='verdana,arial' size='2'><br><br><br>You could not be logged in. 

        You must be logged in to view this page..";

  do_html_url("login.php", "Login");
echo "</font><br><br><br>";
do_html_footer();

  exit;

}
