Session Help

[michaelowen]

Hello everybody,

I am trying to pass a variable into a form, and I am having issues.

Right now here is what I have:

-config file (this is correct)

-include file: this verifies their login is correct, and then passes them to one of 4 pages (depending on the category taken from the db).

My problem is that i want to pass another variable into either of the 4 forms i present.

Here is what i have so far:

?php

include("include.php");

$db = mysql_connect("localhost", "root", "............");

mysql_select_db("....",$db);

$query="SELECT * FROM captain WHERE username ='$username' ";
$result=mysql_query($query);

$mydata = mysql_fetch_array($result);
//echo $mydata[team_category];

if($mydata[team_category] == 'school')
{
header('Location: [url]http://www............php[/url]');
exit;
}
if($mydata[team_category] == 'youth')
{
header('Location: [url]http://www........php[/url]');
exit;
}
if($mydata[team_category] == 'usatf')
{
header('Location: [url]http://www........php[/url]');
exit;
}
if($mydata[team_category] == 'corporate')
{
header('Location: [url]http://www.......php[/url]');
exit;
}
if($mydata[team_category] == 'volunteer')
{
header('Location: [url]http://www........php[/url]');
exit;
}
?>

how could i pass another variable ($teamname) into whatever page it forwards to?

Should I start a session on this page, and then use a global $_SESSION on the subsquent pages, and finally unregister at the end of the form?

you can pass it thru the querystring like

header('Location: [url]http://www............php?teamname=[/url]' . $teamname . ');

then access it on the next page with

$_GET['teamname']

[treds1]

include the variable with the url

eg

if($mydata[team_category] == 'school') 
{ 
header('Location:[url]http://www............php?teamname=[/url]$teamname'); 
exit; 
} 

then in next page call

$teamname=$_GET['teamname'];

hope this is of some help

I'm a bit unsure what you mean by the 2nd example, however would I need to run another query to find the appropriate team associated with the username?

here is what I have to pass the variable, but now i can't verify and get it to display:

login.php page:

header('Location:<a href="http://www.......php?teamname=" target="_blank">[url]http://www........php?teamname=[/url]</a>$teamname');
exit;

is this syntax correct?

target page:

$teamname=$_GET['teamname'];

How can I display $teamname in a form?

dont know what is going on with the code snippet i posted earlier im sure i didnt write that

what i meant to put is

if($mydata[team_category] == 'school')
{
header('Location: [url]http://[/url]
www.example.php?teamname=$teamname');
exit;
}

this will post the $teamname variable with the url if you look in address box on browser will see somthing like

www.example.com?teamname=liverpool

then to get this variable in the next page, use

$variable

= $_GET['teamname']

to display $teamname in a form just set value of field to <? echo $teamname ?>

[stolzyboy]

pretty much exactly like i had, except if you have your $variable in the sinqle quotes, it won't parse as $variable, it will merele print $variable

[michaelowen]

Ok, i'm very close, however the url passing syntax is strange.

When i use the Stolzboy example, there is a missing single quote someplace, and the other simply passes the phrase "$teamname".

also i need to assign the $teamname variable as well. Is this correct:

$queryteam="SELECT * FROM captain where username ='$username' ";
$resultteam=mysql_query($queryteam);
$myteamdata=mysql_fetch_array($resultteam);
$teamname=$myteamdata[team_name];

then i can pass through the header, and call it with:

<? echo $teamname ?>

is my declaration of $teamname correct, and what is the correct syntax for the header?

[treds1]

ok ure nearly there by the look of things firstly

$teamname=$myteamdata[team_name];
should be

$teamname=$myteamdata['team_name'];
u forgot to include '

once u have passed with header
eg
www.example.com?teamname=$teamname
use

$teamname=$_GET['teamname'] (if u passed teamname)

then

echo $teamname

[michaelowen]

I finally figured out the proper syntax and it works great!!

Just to note what worked for me to pass the variables through the head:

note the double quotes instead of single to pass the actual variable name.

header("Location: [url]http://[/url]
www.example.php?teamname=".$teamname."");

Thanks everybody for your help!!
