Re: [PHP-DB] How to capture from session and match database
Goltsios Theodore
You can use cookies to keep your info so that you don't pass them from
page to page. A way to do this is:
$email = 'te...@hostname.domain';
session_start();
setcookie('e-mail',$email);
And then retrieve the cookie information using the $_COOKIE array:
$query="SELECT * FROM table WHERE email = '".$_COOKIE['e-mail']."'";
Every browser keeps information about the cookies that already has
accepted. If this is to work for you then check your browser to see if
the cookie exists and keeps all that you need. A good idea is to erase
the previous cookies accepted from your web server.

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.
Hi,
Now I wish to
include "../includes/malls_db_conf.php";
mysql_close();
{
}
?>
THE Problem is:
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

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

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();
$_SESSION['email'] = 'php...@lists.php.net';
//put a real email address here to test with, later remove it and use the
login email id
if( empty($_SESSION["email"]) ) {
header("location:store-login.php");
}
//the above checks if you have a value in your email session variable.
?>
