Authentication is the best solution. So write one controller and store user details and log-in details. Check these details for every request.

Authentication is the best solution. So write one controller and store user details and log-in details. Check these details for every request.

can you elaborate it a little bit

what you could do is setup your site so it asks for BASIC authentication as soon as you visit the site, and set a flag (marker) in a mysql table to show that they are logged in so the user doesnt get asked for a login everytime they visit a page.

hope this helps a bit

please post your code with the session thing so we can edit it to make it work.

login.php

<?php
session_start();
ob_start();
?>
<?php
mysql_connect("IP addr","username","pssword") or die(mysql_error());



mysql_select_db("database") or die(mysql_error());

//if login form is submitted

if(isset($_POST['submit'])) { //if form is submitted

//check whether all the fields are filled or not

if(!$_POST['username'] | !$_POST['pass']) {
die('You did not fill all the fields.');
}

//verifies against database
$_POST['username']=md5($_POST['username']);
if(!get_magic_quotes_gpc()) {
$_POST['username']=addslashes($_POST['username']);
}



$check=mysql_query("SELECT * FROM users WHERE username='".$_POST['username']."'") or die(mysql_error());
//gives error if user doesnot exist
//{

$check2=mysql_num_rows($check);
if($check2==0) {
die('User does not exist');
}
while($info=mysql_fetch_array($check))
{


$_POST['pass']=stripslashes($_POST['pass']);


$info['password']=stripslashes($info['password']);
$_POST['pass']=md5($_POST['pass']);


//gives error if password is wrong

if($_POST['pass'] !=$info['password']) {
die('incorrect password,please try again.');
}
else
//if login is ok then direct them to options page
{
$_SESSION['views'] = 1;	
header("Location:option1.php");	
ob_flush();

?>
<!META HTTP-EQUIV="Refresh" CONTENT="0; URL=option1.php">
<?php

}
}
}
else
{
//if they are not logged in

?>

<form action="<?PHP echo $_SERVER['PHP_SELF']?>" method="post">
<table border="0">
<tr><td>Username:</td><td>
<input type="text" name="username" maxlength="50">
</td></tr>
<tr><td>Password:</td><td>
<input type="password" name="pass" maxlength="50">
</td></tr>
<tr><td colspan="2" align="right">
<input type="submit" name="submit" value="Login">
</td></tr>
</table>
</form>
<?php
}
?>

option1.php

<?php 
session_start();
ob_start();
if(isset($_SESSION['views']))
$_SESSION['views']=$_SESSION['views']+1;
else
{
//header("Location:message.php"); 
echo "session not set"."</br>";	
print_r($_SESSION);
}
?>

evrytime i am getting session not set

Try out a simple example.

<?php
session_start();
$_SESSION['name']="something";
echo $_SESSION['name'];
?>

Tellme if that works.

it works. i have checked earlier,it shows that in the same page it works but in different pages it doesn't work.

How bout another simple example.

<?php //page1.php
session_start();
$_SESSION['name']="something";
echo $_SESSION['name'];
header("location: page2.php");
?>
<?php //page2.php
session_start();
echo $_SESSION['name'];
?>

Does this work ?

Does this work ?

for page2.php my code is

<?php if(isset($_SESSION['name'])) echo $_SESSION['name']; esle echo "session not set"; ?> also i added ob_start() and ob_flush() in the page1.php code. but sadly the output i get is session not set :'( :'([code=php]

You can do it with cookies, i guess. I haven't used cookies much, so I am not much aware of its functions.
Can you show us whats in your php.ini ? (in [session] part)

anything fishy?????????

if(isset($_SESSION))
echo $_SESSION;
esle
echo "session not set";

you might want to change esle to 'else' :)

What browser are you using? Is it set to accept cookies?
You can check if the sesssioncookie is written by looking in your cookies folder.
IE7 has a special option to 'always accept session cookies' this option is standard disabled, so enable it.
IE7 also has a bug in it, that it won't accept cookies from domains with some special chars in the name ( even underscores ).

Could you check your php.ini for your default-charset? I've heard from some people that UTF-8 might place some invisible Char's infront of sesssion_start(), so it won't work.

Also check if /var/lib/php/session exists. The rest seems to be ok!

in /var/lib php dir doesn't exist..

/var/lib/php/session Create a folder called php and under that, create session. Then try !

/var/lib/php/session Create a folder called php and under that, create session. Then try !

i have tried that but not much success. earlier i had tried to give my own path, but still it was the same

Again, check the file you are changing. Because, if you change the values of php.ini, it *has* to change. If it doesn't, then you are changing the wrong file.

but now i have created the dir as specified in my php.ini

Please tell us what browser you are using to view the site and if it accepts cookies

[edit] Off-topic: whoohoo 700 posts, I'm a master poster! [/edit]

restart your apache and try again ! If that doesn't work, then please check what niek_e has posted.

i got it. After creating the directory i gave 0777 permissions to session dir. now everything is working fine.
thankyou guys
