I have a Google Wallet/Checkout BuyNow button with code similar to the following (generated from the site tools):
<form action="..." id="BB_BuyButtonForm" method="post" name="BB_BuyButtonForm" target="_top">
...
<select name="item_selection_1">
<option value="1">$10 Gift Certificate</option>
... other options ...
</select>
<input name="item_option_name_1" type="hidden" value="$10 Gift Certificate"/>
<input name="item_option_price_1" type="hidden" value="10.0"/>
<input name="item_option_description_1" type="hidden" value="A $10 Gift Certificate"/>
<input name="item_option_quantity_1" type="hidden" value="1"/>
<input name="item_option_currency_1" type="hidden" value="USD"/>
<input name="shopping-cart.item-options.items.item-1.digital-content.url" type="hidden" value="https://example.com/gift-certificate?id=1234&amount=25"/>
...
<input alt="" src="https://checkout.google.com/buttons/buy.gif?merchant_id=...&w=117&h=48&style=trans&variant=text&loc=en_US" type="image"/>
...
</form>
Now, when the buyer clicks the button, they can purchase the item and are directed to the digital content URL, but I don't know how I can make the connection to the particular item they purchased. I could put a dynamic id as a URL parameter for the digital content URL, but I still can't see how to connect that to the Google Checkout order number.
For example, I'm using the Notification & Notification History APIs and see a sequence of notifications after purchase, including the notification with information about the buyer and a shopping cart:
<shopping-cart>
<items>
<item>
<digital-content>
<url>https://example.com/gift-certificate?id=1224&amount=25</url>
</digital-content>
<item-name> $25 Gift Certificate</item-name>
<item-description>A $25 Gift Certificate</item-description>
<quantity>1</quantity>
<unit-price currency="USD">25.0</unit-price>
</item>
</items>
I can see that I could parse out the id parameter from the digital-content url, but that seems messy.
Is there a nice way to just include an extra hidden form field and have that value passed through to the notification?
(even with a single item BuyNow button?)
Thanks.
A merchant_id or even arbitrary private data can be passed using:
...
<input type="hidden" name="shopping-cart.item-options.items.item-1.merchant-item-id" value="SKU123">
<input type="hidden" name="shopping-cart.item-options.items.item-1.merchant-private-item-data" value="<opts><token>a5f6b4c</token></opts>">
...
(the merchant-private-item-data doesn't need to be XML, but if you're using the Rails google4r-checkout Gem, using XML as above results the notification parsing it as an item Hash attribute: #private_data={"opts"=>{"token"=>"a5f6b4c"}} )

I am programming in Spring and using Thymeleaf as my view, and am trying to create a form where users can update their profile. I have a profile page which lists the user's information (first name, last name, address, etc), and there is a link which says "edit profile". When that link is clicked it takes them to a form where they can edit their profile. The form consists of text fields that they can input, just like your standard registration form.
Everything works fine, but my question is, when that link is clicked, how do I add the user's information to the input fields so that it is already present, and that they only modify what they want to change instead of having to re-enter all the fields.
This should behave just like a standard "edit profile" page.
Here is a segment of my edit_profile.html page:
First Name:
Here is the view controller method that returns edit_profile.html page:
#RequestMapping(value = "/edit", method = RequestMethod.GET)
public String getEditProfilePage(Model model) {
model.addAttribute("currentUser", currentUser);
System.out.println("current user firstname: " + currentUser.getFirstname());
model.addAttribute("user", new User());
return "edit_profile";
}
currentUser.getFirstname() prints out the expected value, but I'm getting blank input values in the form.
Thanks.
Solved the problem by removing th:field altogether and instead using th:value to store the default value, and html name and id for the model's field. So name and id is acting like th:field.
I'm slightly confused, you're adding currentUser and a new'd user object to the model map.
But, if currentUser is the target object, you'd just do:
<input type="text" name="firstname" value="James" th:value="${currentUser.firstname}" />
From the documentation:
http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html
I did not have a form with input elements but only a button that should call a specific Spring Controller method and submit an ID of an animal in a list (so I had a list of anmials already showing on my page). I struggled some time to figure out how to submit this id in the form. Here is my solution:
So I started having a form with just one input field (that I would change to a hidden field in the end). In this case of course the id would be empty after submitting the form.
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:field="*{id}" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
The following did not throw an error but neither did it submit the animalIAlreadyShownOnPage's ID.
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:value="${animalIAlreadyShownOnPage.id}" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
In another post user's recommended the "th:attr" attribute, but it didn't work either.
This finally worked - I simply added the name element ("id" is a String attribute in the Animal POJO).
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:value="${animalIAlreadyShownOnPage.id}" name="id" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
I am taking a look of using hosted fields / form in Braintree (here: https://developers.braintreepayments.com/guides/hosted-fields/setup-and-integration/javascript/v2).
In the example html form on the above page, all the fields it has are all hosted fields (cc number, exp date, cvv).
My question is: in the same form, I want to add a few more normal form fields, to collect other information, such as shipping address, delivery notes, etc.
I tried and looks like it works at least in sandbox, but since the doc doesn't mention anything like that, I just want to confirm it.
Anyone has some idea?
Thanks
Full disclosure: I work at Braintree. If you have any further questions, feel free to contact support.
You can add any additional fields to the form by just adding more input tags. Using the example from the docs, if I wanted to add first-name and last-name to the form:
<form action="/" id="my-sample-form">
<label for="card-number">Card Number</label>
<div id="card-number"></div>
<label for="cvv">CVV</label>
<div id="cvv"></div>
<label for="expiration-date">Expiration Date</label>
<div id="expiration-date"></div>
<label for="first-name">First Name</label>
<input type="text" name="first-name" id="first-name">
<label for="last-name">Last Name</label>
<input type="text" name="last-name" id="last-name">
<input type="submit" value="Pay" />
</form>
I'm trying to create a client side uploads using POST with Signature Version 4 of AWS.
According to the documents
When i'm generating the signature on the server side I get an exact match with AWS signature mentioned in this example page.
However when I use it to upload the page I get this error:
SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method
This is the code I've used:
OpenSSL::HMAC.hexdigest('sha256', signing_key(string_to_sign), string_to_sign)
# step 2 in the aws documentation
def signing_key(encoded_policy)
# generate the correct date
date = extract_encoded_policy_date(encoded_policy)
date = time_adjust(date)
# encode all the fields by the algorithm
date_key = OpenSSL::HMAC.digest('sha256',"AWS4#{#secret_access_key}", date.strftime("%Y%m%d"))
date_region_key = OpenSSL::HMAC.digest('sha256',date_key, #region)
date_region_service_key = OpenSSL::HMAC.digest('sha256',date_region_key, #service)
signing_key = OpenSSL::HMAC.digest('sha256',date_region_service_key, 'aws4_request')
signing_key
end
def time_adjust(date)
time = Time.parse(date)
time += time.utc_offset
time.utc
end
After a little search in the net, i've encountered this article. Iv'e implemented this code and the upload succeeded.
signature = OpenSSL::HMAC.digest( OpenSSL::Digest::Digest.new('sha1'), #secret_access_key, string_to_sign)
Base64.encode64(signature).gsub("\n","")```
This is a small Demo for the client side code.
here is some literature I've found useful:
General description
Some code snippets from AWS
What is the differences between the two?
How can I get the first option to work and upload my files?
Is the example in the AWS page no longer valid?
After a research and comparing the AWS post example i found out that there were some redundant fields in the form that made AWS think i'm using SHA1.
After removing the AWSAccessKeyId field from the form and renaming some other fields I managed to make the AWS4 work.
This is the updated Demo
<form id="myForm" action="http://yourbucket.s3.amazonaws.com/" method="post" enctype="multipart/form-data">
<input type="hidden" id="key" name="key" value="uploads/${filename}"/>

I'm building the website based on Joomla 3. I need to disable the validation of the fields: name, username, password1 (the second, because the first is password2) and email2 and use email1 as username (I installed the plugin Email for user authorization).
I have tried to remove these fields in file components/com_users/models/forms/registration.xml but the validation is still remaining. If I don't remove them but only change the rows required="true" to false for these fields the registration doesn't work at all and any user stored in the DB. How can I disable these fields?
It's not an easy workaround, and you will need some basic knowledge of Joomla and PHP, but I'll try to explain it to you as simple as i can.
>>> Creating view template override
First of all you will need to create your Registration view template override (to keep it Joomla update proof). To do so, create folder /templates/YOUT_TEMPLATE/html/com_users/registration and copy /components/com_users/views/registration/tmpl/default.php file there.
From now on you can modify registration output in your template folder.
>>> Modifying registration form output
By default Joomla takes all fields from form file /components/com_users/models/forms/registration.xml, where they are defined, and outputs them in a view. But if we don't want to use ALL the fields, we need to output fields manually.
My example code only output E-mail and Password fields for registration. Here's a sample code to do so: (default.php file)
<?php
defined('_JEXEC') or die;
JHtml::_('behavior.keepalive');
?>
<div class="grid_8" id="register_block">
<div class="content_block">
<h1>Registracija</h1>
<div class="login<?php echo $this->pageclass_sfx?>">
<form id="member-registration" action="<?php echo JRoute::_('index.php?option=com_users&task=registration2.register'); ?>" method="post" enctype="multipart/form-data">
<div>
<div class="login-fields">
<label id="jform_email1-lbl" for="jform_email1">E-mail:</label>
<input type="text" name="jform[email1]" id="jform_email1" value="" size="30">
</div>
<div class="login-fields">
<label id="jform_password1-lbl" for="jform_password1">Password:</label>
<input type="password" name="jform[password1]" id="jform_password1" value="" autocomplete="off" size="30">
</div>
<button type="submit" class="button"><?php echo JText::_('JREGISTER');?></button>
<input type="hidden" name="option" value="com_users" />
<input type="hidden" name="task" value="registration2.register" />
<?php echo JHtml::_('form.token');?>
</div>
</form>
</div>
</div>
</div>
Please note, that I've also replaced task value from registration.register to registration2.register, I did this to bypass some of validation rules using my own controller.
>>> Creating controller override
Locate file /components/com_users/controllers/registration.php and create a copy of it called registration2.php in same folder.
Open file registration2.php and change It's class name from UsersControllerRegistration to UsersControllerRegistration2
From now on Joomla registration form will use this class to create a new user.
Find a method called register and find this line:
$requestData = JRequest::getVar('jform', array(), 'post', 'array');
This is where Joomla get's registration form data. Add the following lines:
$requestData['name'] = $requestData['email1'];
$requestData['username'] = $requestData['email1'];
$requestData['email2'] = $requestData['email1'];
$requestData['password2'] = $requestData['password1'];
It will add missing registration info, and help you pass validation.
NOTE: This is a sample code, to show the main logic. If anyone has a better solution, I'd be more than happy to hear it.
Following same idea, a simpler solution might be just including hidden inputs with values in com_users\views\registration\tmpl\default.php above
<button type="submit" class="btn btn-primary validate"><?php echo JText::_('JREGISTER');?></button>
add
<input type="hidden" id="jform[username]" name="jform[username]" value="username" />
<input type="hidden" id="jform_name" name="jform[name]" value="name" />
It would pass the validation and you would no longer need to override controllers etc.
I need some help with the following issue. I am pretty new to JavaScript so this one is pretty tough for me. Any help would be greatly appreciated!
We have a form for registration that is already in use and I need to make some amends to it to enhance its usability. The form itself already contains several validation scripts and I need to add in a new one - an error message to appear next to the mobile field. I am unable to amend the form HTML itself so I have to do everything by javascript – I need to bind the new function to the submit button so that it fires AFTER all the other validations (field highlight, pop ups), but before the page turns over.
Here is the form (I have just left in the feild i need to amend) :
<form method="post" action="#" id="register_form" class="validate">
<input type="hidden" name="page" value="" />
<input type="hidden" name="unregistered" value="false" />
<fieldset>
<legend>I am a new online customer</legend>
<div class="element">
<label for="mobile_number">Mobile:**</label>
<input name="mobileNumber" type="text" id="mobile_number" title="Please enter at least one number" class="text validate {validate:{minLength:10, eitherOr:'#telephone_number', messages:{minLength:'Please enter a valid phone number (at least #NUM digits long)', eitherOr:'Please enter either your Telephone or Mobile number'}}}" />
</div>
<div class="element continue_shopping_cont submit">
<button type="submit" class="submit button small_button"><span>Register</span></button>
</div>
<input type="hidden" name="secure_from" value="" />
</fieldset>
</form>
Could someone help show me how i am supposed to do this and how is best to target this field?
