The multilingual aspects will certainly be tricky. Gettext is sort of the standard for doing multilingual things, but in and of itself doesn't really provide much help in understanding *how* to do multilingual right, and can be problematic. Some frameworks do support multilingual sites; I know drupal does, for example, and includes quite a lot of other things that can help you build an e-commerce site rather quickly, but drupal itself has a rather steep learning curve. Passages of just plain text aren't that difficult; it's when you start constructing displayed text dynamically that it will be trickier, for certain. Just thinking off the top of my head; you will likely need something other than just gettext with it's separate language files for things like product descriptions. I think it gets rather difficult, and probably bad form, to have your separate strings in files in your code base linked to data base entries; simpler just to store the various multilingual data base bits in the data base itself. But you can see how complex it gets. At any rate, I hope you have a fair bit of experience in building dynamic internet sites already, this is not going to be easy. ---End Message--- ---BeginMessage--- Hello Everyone, Hope all are well.

Nelson You could use an existing templating solution, like Smarty, although for what you want to do it might be overkill. A few str_replace() calls shouldn't produce too much overhead, but it depends on the size of the text string in question. If it's just a couple of paragraphs of text, no problem, something closer to a whole chapter of a book will obviously be more expensive. You could try eval() on the block of text, but if you do, be really careful about what text you're using. I wouldn't recommend this if you're using any text supplied by a user. As a last option, you could have the text stored as separate parts which you join together in one string later. This might be less expensive in terms of processing power required, but it also makes maintenance more of a hassle later. Thanks, Ash http://www.ashleysheridan.co.uk

Thanks, Ash http://www.ashleysheridan.co.uk Hi Ash, Yep, smarty would be way more than I need right now. I'm just dabbling with various things, trying to learn more about PHP. And my first thought was to split the components, which worked fine. Then I tried a HEREDOC which did allow variable substitution. This attempt is a move up from that, trying to generalize things a bit more. My input will be 100% generated by me, but in the back of my mind I'm looking towards the ability to use user supplied strings. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Just define the value for the variables before defining the value for
the message.
Note that $message has to use double quotes for the expansion. Also
consider using HEREDOC instead of the double quotes.
You may want to put your message in a text file and using the include
function.
Hi Stephen,
My message is in a text file, but I'm using fopen and fread in a self-defined
function, so message is actually defined as (GREETER_FILE is a defined
constant):
function print_greeting($user_name)
{
$handle = fopen(GREETER_FILE, r);
$message = fread($file_handle, filesize(GREETER_FILE));
$msg_text = str_replace(USER, $user_name, $message);
print($msg_txt);
}
And my text file is simply:
$cat greet.txt
Hello USER. How are you today?
If I change USER to $user_name in the text file and change the print function
parameter to $message, $user_name gets printed verbatim. In other words
the greeting on my page becomes:
Hello $user_name. How are you today?
I want to pass the name Nelson to the function, and have it output:
Hello Nelson. How are you today?
after the function reads in text file input that contains a variable placeholder
for the user name. I actually had a HEREDOC in the function, and that worked.
But by reading a file instead, I can make things more flexible. I'd rather be
changing a text file instead of a code file.

I use the include(template) method for this alla time, it works

what your print_greeting function does less the actual printout, but
using php variables instead of a str_replace. Also, this way the
templates can be stored elsewhere, outside the actual code base if

Once you have figured out the business practices, coding them should be easier, I'd say, but doing it the other way 'round seems like would lead to confusion. Some questions from a really non-business person: 1. Why are you offering discounts at all? What do you hope to accomplish by offering discounts? 2. Who qualifies for which discounts and why? 3. Do discounts apply to just the base merchandise, or the whole end piece, with whatever customisations it might have, and if so or if not, why? 4. Are there different discount rates applied to base merchandise and subsequent customisations, and if so, why? 5. Is there any reason to make this complicated, or instead just offer a flat rate discount on final price, before taxes and SH? My appologies if this is an OT thread. I was in the midst of coding these things when I asked it. Yes, it is a little confusing. This is a small t-shirt company a friend and I are putting together. I have thought out most of the business logic for the company and the website. The only thing I guess I forgot to plan in was these discounts and how to apply them. I currently have discounts per item and per the cart. The discounts are set up to apply on birthdays and added by admins for discounting items to clear inventory. The cart discounts are set to apply at a certain interval of purchase amounts. For eg. (and im really just throwing numbers) if someone buys $1,000 worth of merch, they are sent a 50% off your cart discount to their email. I guess the question was more how to apply the discounts to the cart. Discount item + miscellaneous or just item. Discount cart or cart + shipping + handling. I was also asking if anyone had or knew of a sample script I could pick apart. That was probably the programing part of the question. But thank you guys for taking the time to answer. I believe it helped. We will see.. :) Best, Karl DeSaulniers Design Drumm http://designdrumm.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Easy standard stuff.

$message = Hello $title $user_name
Just define the value for the variables before defining the value for
the message.
Note that $message has to use double quotes for the expansion. Also
consider using HEREDOC instead of the double quotes.
You may want to put your message in a text file and using the include
function.
Hi Stephen,
My message is in a text file, but I'm using fopen and fread in a self-defined
function, so message is actually defined as (GREETER_FILE is a defined
constant):
function print_greeting($user_name)
{
$handle = fopen(GREETER_FILE, r);
$message = fread($file_handle, filesize(GREETER_FILE));
$msg_text = str_replace(USER, $user_name, $message);
print($msg_txt);
}
And my text file is simply:
$cat greet.txt
Hello USER. How are you today?
If I change USER to $user_name in the text file and change the print function
parameter to $message, $user_name gets printed verbatim. In other words
the greeting on my page becomes:
Hello $user_name. How are you today?
I want to pass the name Nelson to the function, and have it output:
Hello Nelson. How are you today?
after the function reads in text file input that contains a variable placeholder
for the user name. I actually had a HEREDOC in the function, and that worked.
But by reading a file instead, I can make things more flexible. I'd rather be
changing a text file instead of a code file.
The reason you get $user_name printed is because of the way you are
populating the variable $message. You need to have $user_name embedded
in double quotes or a HEREDOC when PHP parses $messsage. And $user_name
has to have already been defined.
Here is a sample from one of my sites. It is a simple one for the
contact page.
=contact.php
?php
$thispage = Contact;
$contenttop = p$thispage/p;
$contentbody = HEREDOC
pstep...@roissy.ca/p
HEREDOC;
require_once include.php;
require_once utilities.php;
echo $header . $markup;
=
The common stuff for every page is defined in the file include.php. I
define the variable $markup in that file.
Here is the definition for $markup
$markup=HEREDOC
body
div id=all
div id=top
img src=$titlepng alt=$title /
/div
div id=main
div id=mainrow
div id=left
$leftimage
div id=mainnav
ul
$menu
/ul
/div
/div
div id=content
div id=content-top
$contenttop
/div
div id=content-body
$contentbody
/div
div id=content-bottom
/div
/div
/div
/div
div id=footer
$copyright
/div
/div
/body
/html
HEREDOC;
There is lots more code, but this is the important stuff.
By using require_once instead of fopen and fread, I have simpler code
and PHP evaluates the embedded variables in $markup without any need to
use string functions.
In your case, I would make the file greeter.php
=greeter.php===
$message = Hello $user_name. How are you today?
===
You replace the fopen and fread stuff with a require_once function and
$message gets included and the user name resolved all in one line of code.
Hope this helps

Aha! Thanks for the more detailed explanation. I totally misunderstood your
first reply. I understood why I was seeing $user_name instead of Nelson,
but I did not understand what you were trying to tell me.
My greeter file is now:
?php
$message=HEREDOC
Hello $user_name.
How are you today?
HEREDOC;
?
And my function is simply:
function print_greeting($user_name)
{
require_once GREETER_FILE;
print($message);
}
Now when I call the function, passing the string Nelson, it is printing
exactly as I wanted. I used a HEREDOC in the GREETER_FILE because I want to
make it more than that one message, and I want to preserve the line breaks
and formatting when I do.
From what I've been reading based on other replies, I think templating
will be the way for me to go at some point. I am trying to design a fairly
simple site that will be used internally as a front-end to a simple inventory
database that I've designed. The back-end works fine, but command line result
sets don't appeal to others, so I've embarked on a front-end design. Your
help has gotten me over this step and I can start to expand things. I find
I learn best when I start with some basic functionality and build it up. My
first incarnation was to simply build a static page that output exactly what
I put into it. Once I got that going, I then broke parts off into functions,
and then added parameter passing to the functions. I've already explained
where it went from there to here.
Not to detract from the other replies, but you have lead me to exactly what
I was looking for at the moment. I find smarty (and now a couple of others
picked up from reading about smarty) to be fascinating stuff, but I'm nowhere
near that point yet.
Thanks a million!
Nelson

While using the *_once works in many cases, if you're doing a mass
mailing kind of thing, you want to use the standard include/require so
you can re-include it as your variables change:
foreach ($customers as $customer) {
$fullname = $customer['fullname'];
$address = $customer['address'];
// and so on
include(mailing.php);
process($mailing,$customer);
}
where mailing.php defines the $mailing variable as the content that
got included and substituted.
(Back before I came up with this, I was starting off in the same place
as the OP -- and then I just realized wait --- PHP *IS* a templating
system! a voila)
