OllaCart Point of Sale for osCommerce - ocPOS

burt · June 2, 2015

Support thread for OllaCart Point of Sale (ocPOS) for osCommerce

Easy to use, no changes needed to osCommerce files, no database editing needed. Uses osCommerce database natively, so there is no need to worry about regular customers/products/order synchronization. It's all in the same database. Updates done in either ocPOS or osCommerce are instantly visible in both ocPOS and osCommerce.

Installer takes care of needed database changes, files are completely separate.

Formerly commercial, now GPL.

The known issues/bugs are documented in README.txt

As-is. No developer support available at this time. I may or may not have time, so please don't get upset if I don't answer promptly (or at all).

Attribute support, including a mode for QT Pro.

I am not the original developer. I purchased full rights to this several years ago, and have been developing it off and on since. It is now being opened fuly to the community.

I tried clearing cookies with no luck BUT I found the following in another forum....

"

try placing this at the top of your page:
<? ob_start(); ?>

then at the bottom of the page place this line of code:

<? ob_flush(); ?>

"

I don't have a clue about what that does but it seems to have fixed the problem. :)

No, it has merely hidden the problem. For now.

As it says in the error message, the problem is on line 9 of /includes/custom_header.php. Something there is outputting to the browser too early, perhaps an error message. Show us the first 15 lines of that file if you can't find it.

Assuming you just posted the contents of includes/custom_header.php the line

include("includes/custom_header.php");

is too high in the file, it should be lower down:

Posted above is the entire file named /includes/custom_header.php

Line 2 is just the name of the file and should remain commented out. The whole purpose of this file was to give the user a way to put his store or operation name in the header, therefore it's displayed on every page in Olla cart. The original propriatory header was not accessable (edit-able) to the end user.

@@paoraosc You're right Parora. There is problem here that nobody has figured out yet. I downloaded and installed this and I'm getting similar results to yours.

MrPhil · June 8, 2015

Starting at

<table cellspacing="2" width="100%"><tr>

you're outputting HTML to the browser. This file is apparently being called too early in osC, before the rest of osC has finished outputting HTTP headers. Thus, the error message. You've got to move the inclusion of this file to somewhere later in osC. Not knowing how all the pieces of this addition interact, I can't tell you any more than that.

Except that I wasn't very clear. The problem is in the edit you made to login.php - that's where you need to apply my advice.

motorcity · June 8, 2015

It appears the problem has to do with logging in or being logged in.

The install writes several new database tables including pos_users. Go there and change the email address to your email address then click on the forgotpass utility, get a new password, and that seems to clear the whole problem.

I could have missed (skipped), some steps in the install process so if anyone else is trying this please report your results here.

Hey John, Jim, what you posted does fix the problem however the same "headers already sent...." follow the user around if they don't log in.

index.php header.php custom_header.php and login.php have the same basic problem unless you login.

Considering what this contribution is supposed to do (allow in-store sales from your oscommerce database), it makes little sense to operate without being logged in.

♥kymation · June 8, 2015

@@motorcity True, but the code should not throw a PHP error if you forget to log in. A polite reminder message would be nice though.

Joe, you've got a mixture of page files and include files in that list. The change I gave will eliminate one source of 'headers already sent' errors but it may not be the only place they're coming from.

The error arises when a php file has already sent some output and then the page headers are sent.

This can happen if you include a file in the wrong place, as we've been discussing. It can also happen if there's an extra space or lines at the end of a file that's included, like this

?>

There may well be other problems like this in the code editing that's been done.

In fact there's one in the code that I copied and posted back, because there are blank lines before the head of the html page:

if($session->logged_in) {
   header('Location: index.php');
} else {

?>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>

should be

if($session->logged_in) {
   header('Location: index.php');
} else {

?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>

Whenever you get this error, it does tell you in which file the headers were already sent, so you just need to check:

- if it's a file that's supposed to output html, it must have been included too early

- if it's just supposed to be code, it may have spaces, new lines or invisible characters at the end. You can get rid of this problem by omitting the closing ?> altogether

- sometimes people leave debugging "echo"s in their code by mistake, so search a code file for these if you've already checked the above

@@kymation My guess is that Jared (jcall) didn't have all that much time to set this up as a free contribution and then test it much. Keep in mind I didn't post this contrib and I'm not using this code. I am a long time user of a prior version however and I'm hoping to help support this effort where I can.

There's a few things that could be done differently including as you said, "A polite reminder message would be nice".

Also maybe an install instruction at least, or make the default email addy the same as the store email.

@@motorcity: Thank you for the kind words and support. You're a good friend.

@everyone_else: 2.1 is the "stable" version. 2.5 is in use in a few shops, but has more warts (and more features). I am neither an accomplished nor professional PHP developer, as you can likely see in the product. It's more than just a few lines here and there, and I've put many many hours of work into it, but 2.5 isn't as polished as I'd like, as you can plainly see by perusing README.txt.

There is even an alternate layout (look at in index.html and NEW_LAYOUT_index.php) that I was working on, but didn't finish (theme?).

I may or may not be successful finding time to help out, make fixes, etc. I am nearly certain that I won't have time for enhancements, but time may tell us all otherwise.

ocPOS was a huge help for my wife's shop years ago and has made a big difference for others. I hope it is useful for you.

Hey Jared, good to see you.

I did load up the new files and I'd say they look pretty jazzy. (That's good in my book!) Like I said I'll try to help here where I can. Like you, I'm coming up on a huge change in my activities profession-wise and the future is somewhat unknown right now. Best of luck in all you do. Move forward. Relentlessly positive.

I've had a play with this and it seems to work OK, I really didn't like the 90s style design so I've been making it responsive with Bootstrap. That way we can use it in store on a tablet too while we are walking around helping customers. Feel free to have a look.

Did anyone know how to change email template for email sent out for POS order confirmation?
