How to capture from session and match database

Hi,

I have this session code on each page and this is working fine for
authentication:

session_start();
if(!session_is_registered(email)){
header("location:store-login.php");
}
?>

Now I wish to

1)capture the value (userName) from session on one of my pages and
2)match it with the database and
3)display the value in the textfields

This is the code I am using to do this please:

include "../includes/malls_db_conf.php";

$query="SELECT * FROM table WHERE email = '$email'"; <---- Here I am
capturing from the session
$result=mysql_query($query);
$num=mysql_numrows($result);

mysql_close();
{

$shopname=mysql_result($result,$i,"shopname");
$category=mysql_result($result,$i,"category");

}

?>

Showing in the textfield from the database is working fine

THE Problem is:

I am getting only the first row of table to show up and not the one with the
field $userName, meaning the userName is not getting captured from the above
or checking with the table and showing me the value.

It might be a basic one, could you please advice how to achieve that.

Cheers,

Chris

RE: How to capture from session and match database

Hi,

First of all, where you are storing the session variable, it should be
specified as:
$_SESSION['email'] = 'email value' //PHP 4.1.0 onwards

This is preferred to registering global variables. There's a whole lot of
discussion on why.

On the pages you are authenticating, you would correspondingly check for a
value in $_SESSION['email']

!empty($_SESSION['email']) isset($_SESSION['email']) etc, depending on you.

When you code for the session logout, you need to look up the php manual
for session_destroy().

When you would like to retrieve data for a user, you can get the details by
using code like this:
$query="SELECT * FROM table WHERE email = '".
mysql_real_escape_string($_SESSION['email']). "'";

I would suggest you read up a good tutorial on php + mysql

I am not sure why there are curly braces after mysql_close(); or where you
are setting values to $i

mysql_close();
{

$shopname=mysql_result($result,$i,"shopname");
$category=mysql_result($result,$i,"category");

}

The best thing would be to first understand sessions, set variables, echo
values, destroy variables, and then test the sql.

Re: How to capture from session and match database

Hi Naintara,

thanks for your code could you please advice why is the code giving this
error.

"Parse error: syntax error, unexpected T_ISSET in
/path/submit-store-details.php on line 4"

This is coming when I am trying to use your code like this:

session_start();
$_SESSION['email'] = 'emailAddress';
if(!empty($_SESSION["email"]) isset ($_SESSION["email"]));
{
header("location:store-login.php");
}
?>

and then retrieving it in SQL query:

$query="SELECT * FROM table WHERE email =
'".mysql_real_escape_string($_SESSION['email'])."'";

Many thanks.

Chris

RE: How to capture from session and match database

Hi Chris,

What I had sent earlier were some hints, references and some code.
I had recommended reading up on sessions, because it's good to know and
useful to get a handle on it, you'll be able to do these things easily
then.

If you are pressed for time and unable to do so, here is some code you
could use
Do read my comments after // (slashes)

session_start();
$_SESSION['email'] = 'php-db@lists.php.net';
//put a real email address here to test with, later remove it and use the
login email id

if( empty($_SESSION["email"]) ) {
header("location:store-login.php");
}
//the above checks if you have a value in your email session variable.
?>
