I fear I've stumbled into unknown Magento territory. I have exhausted what's left of my Googling abilities and have come up short, so I thought I'd try my luck here.
Our platform is Magento Enterprise 1.9.1.1.
We use an archaic print solution that reads orders via ODBC. As such, we can't have it read from Magento's MySQL database directly (thanks to the high likelihood of change). What I've done is extend Mage_Sales_Model_Order to intercept the _beforeSave() function with direct SQL queries to another database, before returning parent::_beforeSave(). There are likely better ways to have done this, but it's done now, and functional, and regardless it is not where my problem lies.
If any SQL errors are thrown, updates are rolled back and the errors & order data are passed to a function that sends an email to a mailing list with the error information. The email template file in /locale/en_US/template/email/ calls on a .phtml file to process the arrays of data like so:
{{block type='core/template' area='frontend' template='/email/errors/order/beforesave.phtml' orderdata=$orderdata errors=$errors}}
This is functionality I borrowed from /locale/en_US/template/email/sales/shipment_new.phtml. And this is also where I hit my roadblock. The email fires fine from the front end, if errors are encountered when the user is processing an order. If you make order changes from adminhtml, the email is sent, but without the above mentioned block.
I have tried with and without area='frontend' in the block call, and the script exhibits the same behaviour regardless.
I think that the problem may be in my XML, though it finds the template itself just fine from both admin and frontend (and this block is not required to be defined in my XML anywhere). I can also not find any examples of this within Magento's own files, or anywhere on the internet.
Any help would be more than greatly appreciated. This is doing my head in!

Are you setting the "area" for the actual email template? E.g.:
$emailTemplate = Mage::getModel('core/email_template');
$emailTemplate
->setDesignConfig(array('area' => 'frontend', 'store' => $storeId));
Possible duplicate of sharing template between frontend and backend (admin or adminhtml) in magento.
Don't mean to revive a dead question; just tying up the loose end.
#ColinM: My thoughts were the same as yours, but that somehow didn't work for me. Maybe I don't understand the purpose of setDesignConfig(). Anyhow, the link above worked perfectly for me, in the same scenario as that of the original poster.

Theres a ton of videos and websites trying to explain backend vs frontend, but unfortunately none of them explains it in a way that you know how to develop a backend - driven website (at least I haven't found anything good).
So, I wanted to ensure that I understood it and kindly ask you to confirm or correct me on this topic.
Example:
I wanted to build Mini - Google. I have a Database containing 1000 stored websites.
Assumption #1:
Everytime I type something into the search bar, the autofill suggestions change. This means, everytime i type, another website / API gets called returning the current autofill suggestions. On a developer site, this means the website e.g. is a Python script which gets called with the current word typed in as a Parameter and is returning all suggestions as e.g. JSON:
// Client Side Script
function ontype(input):
suggestions = get("https://api.googlemini.com/suggestions?q=" + str(input))
show(suggestions)
Assumption #2:
This also means I could manually call the website containing the Python script, providing a random word and it would always return a JSON containing the autofill suggestions for that word.
Question #1:
If A#1 turns out true but A#2 turns out false, how could I prevent a user from randomly accessing the "API" while still returning results when called by a script?
Assumption #3:
After pressing enter, my website googlemini.com/search?... would be called. As google.com/search reloads everytime searching for a new query (or going to page 2 etc.), I assume, instead of calling an API, when the server gets the client request, it first searches through its database, sorts the results and then returns a whole html as a static webpage:
// Server Side Script
#app.route("/search")
function oncall():
query = getparam("q")
results = searchdatabase(query)
html = buildhtml(results)
return html
Question #2:
Often, I hear (or at least understand it this way) that database and webserver are 2 seperate servers. How would that work? Wouldn't that mean the database server needs to be accessible to the web too (of course it would have security layers etc., but technically it would)? How could I access the database server from the webserver?
Question #3:
Are there, on a technical basis, any other ways to build backend services?
That's it. I would also appreciate any recommendations like videos, websites or others to learn how to technically setup and / or secure backend servers.
Thanks in advance.
For your first question you can yes there is a way to prevent miss use.
What you can do is add identifier to api like Auth token to identify a user and every time a user access the api you can save the count on the server n whenever the count has exceeded a limit within a time span you can reject the call. And the limit can be set in such a way that it doesn't trouble the honest user and punishes the wrong one. There are even more complex and effective methods but this is the basic idea.
For question number to let me explain you a simple concept a database is a very efficient, resourcefull and expensive data storage solution we never want it to be used in a general sense as varible store or something. We always want to access the database in call get the data process the data update the data. So we do it data way and its not necessary you make sepreate server for data base. The thing is we mostly make databse to be accessible to various platforms android, ios, windows. So its better to add some abstraction and keep data base as a separte entity.
For the last, I am not well aware about what you meant by other but I am listing some backend teechnologies, some of these might be used in isolation some of these not some other tools as well.

We are a small school district and I have written a simple form for teachers to report disciplinary problems. The destination spreadsheet has a script bound to it and an onFormSubmit trigger is set.
The script uses the form data using the event object e from the function onFormSubmit(), creates a report in Google Docs, send email notices to relevant people and does a few maintenance tasks. Link to code.
It's been working fine until recently when the trigger occasionally fails to fire. No error message; the form data is submitted. This morning, two teachers in separate incidents entered a form and the trigger failed; a third entered the form and it worked.
The form and sheet are 'owned' by the Dean of Students account and users access the form anonymously on the network (not in Google account). The form is set with VIEW privilege for anyone with a link; the sheet has no privileges, only owner.
I am completely stumped as to why this would work sometimes and not others. Clues?
I recently developed a Google Spreadsheet with multiple sheets that takes data from 4 different forms. When the form data comes in, I have scripts that run multiple calculations and formatting on that data, so the onFormSubmit trigger is crucial for me. I've come across the exact same problem you are having right now.
At first I thought there was something wrong with my code and I checked it over and over again. Then, I scoured the web for answers to why my triggers failed about 10 to 20% of the time. A lot of what I found on Google forums related to problems from Google's side. I found that tons of people faced the same problem I had, but none of them had a definitive fix.
My eventual solution was to create yet another trigger that fires every 8 hours. This runs everything my other triggers run yet again just to make sure everything I wanted to do has been done. Of course, that trigger could fail, too. But so far, I've been checking the sheet (new data comes in about every 6 hours or so) and I haven't had to fix any problems whereas before, I had to rerun scripts daily.
Maybe for your case, you can have a function that goes through and sends emails that previous faulty triggers failed to send. Then have this function fire every however many hours you prefer.
This is probably not a very satisfying answer but it's the best I can do. Good luck!
I am completely stuck on where to start with getting a log-in area for a Clojure site I am building (for fun).
I've looked at several resources, which I'll post below, mercilessly copy/pasted code, and the closest I can get is one of two situations:
The login page takes the login but says that the login failed, though, as far as I can tell, the login matches.
Or I get this error: No method in multimethod '->sql' for dispatch value: null
I'm not sure how to interpret the above error: is this specifying that I need a multi-method or is it specifying that I need to check for null? The null requirement makes no sense at all. I'm not really asking but if anyone wants to give an explanation, that is great.
I tested the output by comparing the results-to-select queries from raw non-hashed data, I've went through 5 variations on this theme, using everything from page-to-page calls to creating new defpartials, multi-methods, defn, etc.
Sources I have used (unfortunately, I can't list all of them being a first-time poster):
This one uses Clojure -> Korma -> PostgreSQL, but the code doesn't seem to work for multiple users?
http://www.vijaykiran.com/2012/01/17/web-application-development-with-clojure-part-2/
This one shows how to use Noir and PostgreSQL (Yes, I am using Noir):
https://yogthos.net:11794/blog/23-Noir+tutorial+-+part+2
The 4Clojure site, but that one uses CongoMongo:
The Heroku Twitter clone, but no mention of how to create logins for one person, much less several.
I also bought Programming Clojure from O'Reilly Press, but once again, nothing about how to create a log-in area.
FIRST EDIT: I was asked to create a github repository of a stand-alone site. This includes a working "Account Creation" area that is found in the welcome.clj file and only a form of the Login area in login.clj.
I was attempting to get some of the same errors working as I had last night and also attempting to get this working before I uploaded the files. I don't have any reasonable starting points yet, thus there is no beginning implementation as of yet. I'm seriously embarrassed at the solutions I've been coming up with, thus I don't want to post them. I get conceptually what I should do, but for some reason, I can't seem to translate this. This is my first github account: my background is Python, Scheme a'la SICP, and some Python + PostgreSQL marketing program I built.
SECOND EDIT: Ack! I can't seem to get the thing to work at all... Yeah, I spent well over 20 minutes (hours) on this one, so I have just have to admit that I don't yet have the requisite knowledge to accomplish this, no matter how many sources I look to. I committed the updated files and all the odd things I tried, including all the variations on login box to running raw SQL. The closest I can come is getting it so that I don't get any errors, but no evidence at all that someone is logged in. Thanks so much for the help and suggestions. I'll most certainly return to this later.

There are a couple of issues that I see. First, in datapass.clj, you're creating an entity with no content. I'm not sure how Korma handles that. It's trying to thread results as inputs to other functions, so I could see how nil gets introduced there.
Secondly, you'll need something to handle the login post. (defpage ...) only handles GET requests by default. You'll need a separate defpage to handle the post. Something along these lines:
(defpage [:post "/login"] {:keys [user-name pwd]}
(if-let [user (db/find-user user)]
(if (noir.util.crypt/compare pwd (:password user))
(do
(noir.session/put! :some-key some-value)
(noir.response/redirect "/success"))
noir.response/redirect "/failed-to-login"))
(noir.response/redirect "/failed-to-login"))
session/put! is how you put data into the session. The default is to use an in-memory store. You'll need to add Ring middleware to use persistent sessions (look at Session Stores).
Also, as luck would have, someone just posted an authentication app for Noir... you may want to take a look: https://github.com/xavi/noir-auth-app
It's a long story, but I am trying to save an internal website from the pointy hair bosses who see no value from it anymore and will be flicking the switch at some point in the future. I feel the information contained is important and future generations will want to use it. No, it's not some adult site, but since it's some big corp, I can't say any more.
The problem is, the site is a mess of ASP and Flash that only works under IE7 and is buggy under IE8 and 32bit only even. All the urls are session style and are gibberish. The flash objects itself pull extra information with GET request to ASP objects. It's really poorly designed for scraping. :)
So my idea is to do a tcpdump as I navigate the entire site. Then somehow dump the result of every GET into a sql database. Then with a little messing with the host file, redirect every request to some cgi script that will look for a matching get request in the database and return the data. So the entire site will be located in an SQL database in URL/Data keypairs. Flat file may also work.
In theory, I think this is the only way to go about this. The only problem I see is if they do some client side ActiveX/Flash stuff that generates session URLs that will be different each time.
Anyway, I know Perl, and the idea seems simple with the right modules, so I think I can do most of the work in that, but I am open to any other ideas before I get started. Maybe this exist already?
Thanks for any input.
To capture I wouldn't use tcpdump, but either the crawler itself or a webproxy that can be tweaked to save everything, e.g. Fiddler, Squid, or mod_proxy.
I'm attempting to move a web app we have (written in Perl) from an IIS6 server to an IIS7.5 server.
Everything seems to be parsing correctly, I'm just having some issues getting the app to actually work.
The app is basically a couple forms. You fill the first one out, click submit, it presents you with another form based on what checkboxes you selected (using includes and such).
I can get past the first form once... but then after that it stops working and pops up the generated error message. After looking into the code and such, it basically states that there aren't any checkboxes selected.
I know the app writes data into .dat files... (at what point, I'm not sure yet), but I don't see those being created. I've looked at file/directory permissions and seemingly I have MORE permissions on the new server than I did on the last. The user/group for the files/dirs are different though...
Would that have anything to do with it? Why would it pass me on to the next form, displaying the correct "modules" I checked the first time and then not any other time after that? (it seems to reset itself after a while)
I know this is complicated so if you have any questions for me, please ask and I'll answer to the best of my ability :).
Btw, total idiot when it comes to Perl.
EDIT AGAIN
I've removed the source as to not reveal any security vulnerabilities... Thanks for pointing that out.
I'm not sure what else to do to show exactly what's going on with this though :(.
I'd recommend verifying, step by step, that what you think is happening is really happening. Start by watching the HTTP request from your browser to the web server - are the arguments your second perl script expects actually being passed to the server? If not, you'll need to fix the first script.
(start edit)
There's lots of tools to watch the network traffic.
Wireshark will read the traffic as it passes over the network (you can run it on the sending or receiving system, or any system on the collision domain).
You can use a proxy server, like WebScarab (free), Burp, Paros, etc. You'll have to configure your browser to send traffic to the proxy server, which will then forward the requests to the server. These particular servers are intended to aid testing, in that you'll be able to mess with the requests as they go by (and much more)
As Sinan indicates, you can use browser addons like Fx LiveHttpHeaders, or Tamper Data, or Internet Explorer's developer kit (IIRC)
(end edit)
Next, you should print out all CGI arguments that the second perl script receives. That way, you'll know what the script really thinks it gets.
Then, you can enable verbose logging in IIS, so that it logs the full HTTP request.
This will get you closer to the source of the problem - you'll know if it's (a) the first script not creating correct HTML, resulting in an incomplete HTTP request from the browser, (b) the IIS server not receiving the CGI arguments for some odd reason, or (c) the arguments aren't getting from the IIS server and into the perl script (or, possibly, that the perl script is not correctly accessing the arguments).
Good luck!
What you need to do is clear.
There is a lot of weird excess baggage in the script. There seemed to be no subroutines. Just one long series of commands with global variables.
It is time to start refactoring.
Get one thing running at a time.
I saw HTML::Template there but you still had raw HTML mixed in with code. Separate code from presentation.
