I currently have a landing page /vouchers and then many pages linked to that for example /vouchers/1, /vouchers/2 etc.
I currently have the functionality that if this is entered /vouchers/1?offer=50 then the form on that page is sent with the offer included in the url.
Now I need to add the functionality so if /vouchers?offer=50 is entered, any page that is then navigated to, will keep these parameters. (for example /vouchers/1 should then include the offer from the url)
I see only one way.
store all "special" parameters in session
in any handler — if "special" parameters are in session — form new url with this parameters and redirect user there
Let me guess :
1. you have a model , named "Voucher"
2. In case you want to see the entry for , let's say , voucher#1 , you see URL voucher/1 (notice the singular form of the word 'voucher')
3. you assign the value of the offer by some interaction by user , for example - link or list . Let's say it's a link . Try this (HAML):
= link_to "Accept this offer and create a new voucher", new_voucher_path(:offer => #offer_value)
(in your case #offer_value = 50)
The following view (or partial ) will be able to read the value in :offer .
You can refer to this useful discusion .
I solved this, probably not in the best way. On the /voucher page, I added if statements to all the links, so if there's an offer in the url, the links are appended appropriately.

This view suppose to show a list of hyperlinks, each pointing to an external URL. The goal is for the user to click one of these links and have their browser open a new tab with the selected URL.
Currently I have the following markup:
#Html.ActionLink("SomeSite", "http://subdomain.mydomain.com/SomeSite")
This markup produces:
http://localhost:58980/AccessInstance/http%3a/subdomain.mydomain.com/SomeSite
instead of :
http://subdomain.mydomain.com/SomeSite
What can I change in my markup to make this work as I expect?
You don't need to use #Html.ActionLink for that. Just use a plain A tag:
SomeSite
Html.ActionLink is specifically for generating links to actions defined in MVC controllers, in the same app. Since you're linking to an absolute URL, you don't need any of the functionality that Html.ActionLink provides.
Two ways :
1. update the database column with full link:
eg SQL:
update ProductTable set ProductLink='http://www.example.com/Product/Mobiles' where ID=123
In asp mvc view
View
2. Hardcode the http part and list from model
View
Hope helps someone.
While a ViewBag is overused and not the best choice most of the time this is something that I had done when inheriting someone else's mvc app to do a quick fix for a URL that I needed to redirect to with a specific dynamically changing querystring parameter
<a target="_parent" href="http://localhost:56332/services/#ViewBag.factory">View Service</a>
Using .NET Core 6
This seems to be the most correct answer:
Link
This will generate the following result:
As you can see at the bottom left corner of the window before clicking the link, the URL address was rendered as it is (NOTE: The cursor was recorded out of place for some reason, that's a ShareX problem, ignore it).
Than link will be directly saved as a nvarchar(750) type (probably any character like type will do the work). No changes to the original link were made before saving it or on reading:
You need to take into account your RouteConfiguration.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}"
because you are specifying the action link as the entire link that you want to redirect.
I would recommend that you use the #rossipedia answer because you can make tricky things like putting a span inside the link
Here to display link that are clickable in index page
<td>
#Html.ActionLink(item.FileName, "../Uploads/Catalogue/"+item.FileName)

am developing an application in which i have to show the customer purchase details supplier wise. for that i have develop user control an add it on page. but the problem it that on user control i need to add a ling to promotional offer page for that supplier which show the current offers of the supplier. for that i have added the hyperlink as fallow to user control
<asp:HyperLink ID="PromoLink" runat="server">Have promo Code ?</asp:HyperLink>
and set the navigation URL as fallow
PromoLink.NavigateUrl = "Promotion.aspx?Filter=" + dt.Rows[0]["SuppId"].ToString();
but when page is load in does not render the navigation url to the link.
i donot why it does not render the url plz help to get out of this.
thanks in advance.
Make sure that the pathing is correct for the NavigateURL property. Try adding "~/" at the start of the NavigateURL or "../" if it is not in the same folder as the current file.
Make sure that the dt.Rows[0]["SuppId"] is actually getting the value that you expect.
Step through code in the debugger to verify that the Page_Load event that you are using is actually executing and modifying the value as you would expect it to.
I have the following relation in my model:
A user can have several consumers
According to that, I call several actions from different controllers that depend on that consumer_id in the URL. So, I do stuff like:
/:consumer_id/products/all
/:consumer_id/locals/all?params...
I want to be able to given that I am in a particular view, let's say /3/products/all, be able to refresh, redirect or whatever is the best to /4/products/all, with a form that shows the different consumers attached to that user.
I know how to display the form, but I fail to see which action should I put given that I want to load the current controller, current action and the current params, except that I want to change the params[:consumer_id] and the session[:consumer_id] to the one chosen by the user in the form of the view.
What's the best or appropriate way of doing so?
This is a link to the same page with the same parameters and one additional parameter:
<%= link_to "Show more results", url_for(params.merge(:per => 100)) %>
If you want to modify a parameter rather than add a new one, you can modify the params hash just as you would modify any hash, and use url_for again.
Inside the view you can access both the current controller using controller_name and the current action using action_name
Your question is not clear. You want to choose consumer_id from your form, then use that consumer id inside the same page or for links to other pages?
If you want to use the consumer id for the current page, you need to use javascript or JQuery to update all attributes of the current page.
If you want to use that consumer id for links,
you may also use JQuery to update all links on your page
Or, you can submit the form to the server with new consumer_id.
I want to pass the id from one action to the next action, but I do not want it seen in the URL. Is there a way to hide it?
Using Symfony, I have created a sign-up done page whose URL should be /signup/done
When the form is processed, I want to redirect to the signupSuccess action and pass the recently created ID for future use. So I use...
$this->redirect('#signup_done?id=' . $sign_up->getId());
The routing is as follows:
signup_done:
url: /signup/done
param: { module: SignUp, action: signupDone }
I have avoided the :id at the end because I don't want it in the URL.
But the resulting URL is /signup/done?id=1
Just as an experiment, I tried putting this on a template.
<?php echo link_to('Sign-up again', '#signup_done?id=1', 'post=true') ?>
Even when using post, the query parameter appears in the URL.
The need is: I want to pass the id from one action to the next action, but I do not want it seen in the URL. Is there a way to hide it?
I set the id as a parameter in the request using $request->setParameter('id', $id) and it was available in the next action.
This kept the URL clean.
If you want to post, you need a form. Back in symfony 1.2 there were helpers that you could call and made you just that - but they were removed for the promotion of promoting good code.
Depending on how you want the 'Sign up again' text to look, you can either create a simple form and a submit button, or create a link, attach a click listener, and create a form there via JS, finally post it.
Any parameter that you pass to the route in url_for, link_to and such end up in the get parameters.
We have been trying to implement shortcodes on an ASP.NET MVC web app that allow users to uniquely invoke a given article/page using an assigned short code.
For e.g.: www.mysite.com/power would map to an actual URL: www.mysite.com/Power/Home/.
I have created various routes throughout the site that map these shortcodes to various actions and controllers within the application. From a shortcode/route point of view, everything is working great.
I, however, noticed a couple of interesting things. I have hyperlinks that I use Url.Action method to generate the URL pointing pages. Many of these pages also have short codes associated with them. For e.g.: I have a link that says:
Go to Power page
This is a page that also has the previously mentioned short-code assigned to it. When I use Url.Action, I ideally expect it to create a link as /Power/Home/Index or /Power/Home, but since I also have a route constraint mapped to it, it now generates the link as /power.
Is there a way I can just use the actual link URL when generating links? I only want short-codes when I am sending out emails etc. I want the site to generate actual URLs.
This may or may not be possible, but I wanted to see if there were any ideas out there that I could use.
Anup
Index and Home are likely defined in your route table as defaults for the Action and Controller element. When you generate the Url it wont include the defaults if they aren't needed.
You could write your own Action overload or helper, which would allow you to take more direct control of the generated URL or action link. You could approach it from two different ways: 1) a helper to generate short-code specific urls and links, and/or 2) a helper to generate the full url and/or link. If Url.Action is returning the short-code version due to your routing configuration, I'd think a good place to start would be the second option, creating a helper/extension method that will generate the full url for you.
Here's how I solved this:
Instead of naming a route with short code to point to the action url, I made the route point to a different Controller action which would then redirect to the actual route that I want it to.
For e.g.: Originally I had the code "power" defined in the route table such that it would point to www.mysite.com/Power/Home.
Now instead of pointing it to that action - Index, controller - Home, area - Power, I make it resolve to: action - Power, Controller - Home, Area - ShortCode.
In the controller now, I simply do a RedirectToAction("Index", "Home", new { Area = "Power" });
This ensures that the actual links to /Power/Home do not resolve to the shortcode "power".
This is a simple fix increased the work by a little bit, but works like a charm.
