I have a Request Quote for in Umbraco using Contour and upon submitting successfully this form, the use is redirected to a Thank You Page (In settings in the Contour, i'm using "$currentPage/* [#isDoc]/#id" to redirect to the Thank you page). For some marketing actions, i need to parse the email value of the form to the URL like this for tracking purposes:
http://www.mywebsite.com/thank-you.aspx?email=xxx#y.com&recordid=123456789
Since "#" is a reserved character, we can make it to "%40".
How can i do that? Any idea please.
I'm not 100% sure if this is possible. You could try writing a workflow that does a redirect? That MIGHT work, it depends if the workflows are carried out synchronously or not.
Another option is that the record ID is passed to the thank you page, you could write a bit of code to fetch the email address from the record using the Contour API, and manually run some tracking JS on page load.

I am working w/ the Event Brite API and I have a need that I am trying to figure out the best approach for. Right now, I have an event that people will be registering for. At the final step of the registration process, I need to ask them some questions that are specific to my event. Sadly, these questions are data-driven from my website, so I am unable to use the packaged surveys w/ Event Bright.
In a perfect world, I would use the basic flow detailed in the Website Workflow of the EB documentation, ending upon the "3rd Party Next Steps" step (redirect method).
http://developer.eventbrite.com/doc/workflows/
Upon landing on that page, I would like to be able to access the order data that we just created in order to update my database and to send emails to each person who purchased a seat. This email would contain the information needed to kick off the survey portion of my registration process.
Is this possible in the current API? Does the redirect post any data back to the 3rd party site? I saw a few SO posts that gave a few keywords that could be included in the redirect URL (is there a comprehensive list?). If so, is there a way to use that data to look up order information for that order only?
Right now, my only other alternative is to set up a polling service that would pull EB API data, check for new values, and then kick off the process on intervals. This would be pretty noisy for all parties involved, create delay for my attendees, and I would like to avoid it if possible. Thoughts?
Thanks!
Here are the full set of parameters which we support after an attendee places an order:
http://yoursite.com/?eid=$event_id&attid=$attendee_id&oid=$order_id
It's possible that order_id and attendee_id would not be a numeric value, in which case it would return a value of "unknown." You'll always have the event_id though.
If you want to get order-specific data after redirecting an attendee to your site, you can using the event_list_attendees method, along with the modified_after parameter. You'll still have to look through the result set for the new order_id, but the result set will be much smaller and easier to navigate. You can get more information here: http://developer.eventbrite.com/doc/events/event_list_attendees/
You can pass the order_id in your redirect URL in order to solve this.
When you define a redirect URL, Evenbrite will automatically swap in the order_id value in place of the string "$order_id".
http://your3rdpartywebsite.com/welcome_back/?order_id=$order_id
or:
http://your3rdpartywebsite.com/welcome_back/$order_id/
When the user completes their transaction, they will be redirected to your external site, as shown here: /http://developer.eventbrite.com/doc/workflows/
When your post-transaction landing page is loaded, grab the order_id from the request URL, and call the event_list_attendees API method to find the order information in the response.
I'm currently coding all of the account management functionality for my site, and have already implemented the account activation and password reset systems by e-mail. The e-mails each contain a link to a servlet (with the appropriate parameters attached to the end), which does all the processing. Tests for the systems have gone well, however I have one question.
If the link's text is the same as its address, is there any reason to include traditional manual activation/password reset page (a page with a form where the request parameters in the activation or reset link would be entered in to the appropriate fields)? If the link doesn't work in the e-mail, the user can always copy and paste it. Is there any particular reason why sites still have seperate pages dedicated to these actions? And should I allow it?
You never know for certain the kind of transformations your email will undergo before being displayed to the person that will eventually use your reset facility. Combined with clueless users this may pose a problem.
An example: Since reset/activation links can be quite long they may be partially wrapped onto a new line after a transformation from HTML to plain text. Inevitably this will someday happen to a user that does not know how to deal with that situation.
Therefore it might prudent to provide the backup method of just entering the code in a text field which on submit performs the GET that was intended in the first place.
You are of course free to decide that your site does not need the business of said type of user and skip implementation of the manual method!
I am trying to build a free web application using ruby/rails It should be able to send sms through online forms of various mobile operators. (like this one (in russian)).
So, I need to
wait for the user, who wants to send an sms through my website.
establish connection to operator website. Probably, using Mechanize.
retrieve captcha
show captcha to the user
allow user to enter a message and captcha
submit form on operators website (with message, captcha, phone number)
The connection to the operator website should be alive during all this process (otherwise captcha will change). As far as I understand, I need to create a (sub)process each time sms is sent.
Could you please advise what is the best way of handling this in rails\ruby?
I am still rather new to web-development...
Should I use threads? forks? popen? using PTY? some external gem? How should I communicate with my process?
Assuming there's nothing special about the operator's web site, no, you don't need to keep a connection alive during the whole process. Generally speaking, forms on web pages work like this: You visit the URL, your web browser downloads the page with the form on it. In your case, it will also have an <img> tag or similar to show the CAPTCHA. Once your browser has downloaded the page, the connection is severed. After you fill out the form and click on Submit, your web browser opens a new connection to the server and sends the data, and the server sends its response (whatever page is shown after you click Submit).
All your program has to do is emulate this experience. So: 1) Download the page with the form on it. Scrape the form fields (make sure you don't miss any hidden fields--with a CAPTCHA there will probably be some) and the CAPTCHA. 2) Build a page to show your user that includes the CAPTCHA and a form with all the fields they need to fill out. If there were hidden fields in the original form, make sure you include their values (as hidden fields in your form) as well, because when the user submits your form you'll need them. 3) Then, when the user submits your form, send the data, including the hidden values and what the user entered for the CAPTCHA, to the operator. 4) Finally, check if the operator indicated success, and build a page to tell your user.
If you're doing this in Rails, you'll probably have two methods in your controller: One called e.g. 'show' (steps 1 and 2 above) that will scrape the CAPTCHA and other info from the operator's site and show the user your form view, and one called e.g. 'send' (step 3 and 4 above) that the form will submit to, and which will take their data and send it to the operator's web site, collect the response and tell your user if it was successful or not.
Note: You'll want to read the operators' terms of service before you bother with any of this. I'm fairly certain that this kind of thing will be against their TOSes and if they notice your server sending a lot of requests their way they're going to block you pretty quick.
To answer another question of yours, you can use DRb or background_job (aka BJ) to actually accomplish the sending in the background so that after your user submits the captcha they don't have to wait for the response. Or you could wrap this in ajax and have the DRb/BJ process notify you when the sms sending has happened so you can notify the user of success or any problems.
Typically opening threads in Ruby is something to avoid as there are so many great gems that do what we need. Not to say that you shouldn't use threads, just that for the most part it's probably already been done really well.
I have made a little app for signing up for an event. User input their data and click "sign me in".
Now sometimes people are double in the database, the exact same data that got inserted 2 times very quickly after each other. This can only mean someone clicked the button twice, which caused two posts to happen.
This is common web problem, as credit card apps and forum apps often say: "Clicking once is enough!".
I guess you could solve it by checking for the exact same data to see if the post is unique, but I wonder if there are other methods.
This ofcourse does not count for ASP.NET webforms, because POST doesn't matter as much.
While JavaScript solutions can disable the submit button after it has been clicked, this will have no effect on those people who have JavaScript disabled. You should always make things work correctly without JavaScript before adding it in, otherwise there's no point as users will still be able to bypass the checks by just disabling JavaScript.
If the page where the form appears is dynamically generated, you can add a hidden field which contains some sort of sequence number, a hash, or anything unique. Then you have some server-side validation that will check if a request with that unique value has already come in. When the user submits the form, the unique value is checked against a list of "used" values. If it exists in the list, it's a dupe request and can be discarded. If it doesn't exist, then add it to the list and process as normal. As long as you make sure the value is unique, this guarantees the same form cannot be submitted twice.
Of course, if the page the form is on is not dynamically generated, then you'll need to do it the hard way on the server-side to check that the same information has not already been submitted.
Most of the answers so far have been client-side. On the server-side, you can generate a hidden field with a GUID when you first produce the form, and then record that GUID as a submitted form when the post is received. Check it before doing any more processing.
Whenever a page is requested from the server , generate a unique requestToken , save it in server side,mark status as NOT Processed and pass it along with the current requested page. Now whenever a page submit happens , get the requestToken from the "POST"ed data and check the status and save the data or take alternate action.
Most of the banking applications use this technique to prevent double "POST"ing.So this is a time proven & reliable way of preventing double submissions.
A user-side solution is to disable the submission button via Javascript after the first click.
It has drawbacks, but I see it often used on e-commerce websites.
But, it won't never replace a real server-side validation.
Client side techniques are useful, but you may want to couple it with some server side techniques.
One way to do this is to include a unique token in the form (e.g. a GUID or similar), so that when you come to process the form you can check to see whether the token has already been used, preventing a double submission.
In your case, if you have a table with event visitors, you might include this token as a column.
A client-only solution won't be enough, as stated in many of the answers here. You need to go with a server-side fail-safe.
An often overlooked reason that disabling the submit button doesn't work is, the user can simply refresh the submit target (and click OK on the "are you sure you want to resubmit the POST data?" dialog). Or even, some browsers may implicitly reload the submitted page when you try to save the page to disk (for example, you're trying to save a hard-copy of an order confirmation).
Almost no one has js disabled.
Think about coding your e-commerce website for the 70 year old woman who double clicks every link and button.
All you want to do is add a javascript to prevent her clicking "Order Now" twice.
Yes - check this at the server side too "be defensive" - but don't code for that case. But for the sake of a better UI do it on the client side too.
Here are some scripts that I found:
//
// prevent double-click on submit
//
jQuery('input[type=submit]').click(function(){
if(jQuery.data(this, 'clicked')){
return false;
}
else{
jQuery.data(this, 'clicked', true);
return true;
}
});
and
// Find ALL <form> tags on your page
$('form').submit(function(){
// On submit disable its submit button
$('input[type=submit]', this).attr('disabled', 'disabled');
});
None of the solutions address a load-balance server.
If you have some load balancer, send a UUID (or any type of unique number) to the server to store and read again will not work well if the server is not aware of other servers, because each request could be processed by a different server in a stateless environment. These servers need to read/write to the same place.
If you have multiple servers you will need to have some shared cache (like a Redis) among the servers to read/write the unique value in the same place (what could be an over-engineering solution, but works).
Client side alteration is a common technique:
Disable submit button
Change the screen to a "please wait" screen
If the form was modal, changing the screen back to their usual process (this has the benefit of making things look really slick)
But it's not perfect. It all relies on JS being available and if that's not the case, without back-end duplication detection, you'll get duplicates still.
So my advice is to develop some sort of detection behind the scenes and then improve your form to stop people with JS being able to double-submit.
You can track the number of times the form's been submitted and compare it to the number of unique visits to the page with the form on it in the session.
Beside the many good techniques already mentioned, another simple server-side method, that has the drawback of requiring a session, is to have a session variable that is switched off on the first submit.
As a part of the signup process for my online application, I'm thinking of tracking the source and/or search keywords used to get to my site. This would allow me to see what advertising is working and from where with a somewhat finer grain than Google Analytics would.
I assume I could set some kind of cookie with this information when people get to my site, but I'm not sure how I would go about getting it. Is it even possible?
I'm using Rails, but a language-independent solution (or even just pointers to where to find this information) would be appreciated!
Your best bet IMO would be to use javascript to look for a cookie named "origReferrer" or something like that and if that cookie doesn't exist you should create one (with an expiry of ~24hours) and fill it with the current referrer.
That way you'll have preserved the original referrer all the way from your users first visit and when your users have completed whatever steps you want them to have completed (ie, account creation) you can read back that cookie on the server and do whatever parsing/analyzing you want.
Andy Brice explains the technique in his blog post Cookie tracking for profit and pleasure.
