Further to that... if you need to add more columns of information. Let's
say:
Text Name name="textname[id]"
Checkbox name="checkbox[id]"
Different checkbox name="otherchkbox[id]"
If you set them all up to use arrays, you can process the form quite
nicely like this:
foreach ($_POST["textname"] as $id => $value) {
// access other items with:
$checkbox = $_POST["checkbox"][$id];
$other = $_POST["otherchkbox"][$id];
}
I'm sure there are other ways of doing it, but that's the one I like. :)

[PHP] confusing problem or am just plain confused....
Hi,
I dont know how exactly to explain this but will do my best, i have many of
the following lines in a page:
each line of course has a differient id[] value and package value.
Everything is working fine with the just id[] value but now i need to add
the package value too...but the problem is when i submit the form all the
hidden fields are getting submitted when i only need the hidden "package"
value of the ticked checkbox...is there any way to do that? or alter the
above so that each id[] can have 2 values?
In the above example i am getting upto 5 id numbers after i get the
numbers i am using it like so:
if(isset($id[0]))
{do things}
to get a better idea of what i am talking about if the above is just too
darn confusing check out http://bestwebhosters.com/search.template2.php
note that most of the links are deadlinks as this is still in development.
Any and all help appreciated.
Cheers,
-Ryan

RE: [PHP] Confusing Problem
you'll need to make them global then...
that's one thing that kept getting me when I started using php, global vars
are only global if you tell them to be sorta like "local to the global
scope" or something like that :)

they are in the same script outside the function.
all the admin functions reside in a admin_func.php
with the $db_host, etc, etc variables assigned before it.

Re: [PHP] Confusing Problem
Just as DL Neil implied, your variables are outside the scope of the
function. set them global within your function.
See: http://www.php.net/manual/en/language.variables.scope.php

Remember the idea of the "scope" of a variable? (if not, please RTFM)
Where do the values of $db_host, $db_user, etc come from?
They are not in the argument list for verify_user().

[PHP] Confusing Problem
I am really baffled by this problem. I have tried so many things to get
this working but to no avail. Here is the
actual code:
function verify_user($username, $password){
$conn = mysql_connect($db_host, $db_user, $db_pass) or
die("Error while connecting to Database System.");
$select_db = mysql_select_db($db_name) or
die("Error could not select the database");
$query = "SELECT FROM users WHERE username='$username'";
$result = mysql_query($query) or
die("Unable to get query");
$rows = mysql_fetch_array($result);
$password = md5($password);
if($rows["password"] == $password){
print "You have been verified as $username.";
print "Registering your session.";
}
else{
print "Error: Bad username or password.";
print "Please go back";
}
}
Anyways the problem is I cannot get it to even get to the database. It
works when I try to connect in the actual code before I call this function.
Like for example in index.php
$conn = mysql_connect($db_host, $db_user, $db_pass) or
die("Error while connecting to Database System.");
$select_db = mysql_select_db($db_name) or
die("Error could not select the database");
verify_user($username, $pass);
But when I do it that way it won't let me run a query right. I am so
baffled. Any input would be appreciated. Thanks.

RE: [PHP] confusing problem w/sessions
On which platform do you run?
set display_startup_errors = On
so that you eventually will see any php initialization problem (like the
folder where session data is stored being not accessible because of
permission restrictions...I say that because I ran into this problem)
to recap, code should be on first page:
and on second page:
should return:
Value of a is: something

start your session before sending any html output to browser
check that register_globals is on
if not use $HTTP_SESSION_VARS("a") instead to reference your session var
assign a value after having initialiazed your var not before

[PHP] confusing problem w/sessions
Dear sirs; i have a simple snippet of code : i am trying to understand how do session work. Accessing at this document directly from the server (it is a SuSE 7.2 PE - running PHP 4.0.4 and apache 1.3.9) i find out the following problem: Warning: cannot send session cookie - headers already sent (output started at ) and Warning: cannot send session cache limiter - headers already sent (output started at ) The matter is that if i access this variables from another page, they seem to be empty... How can i solve this little confusing problem?
