I have a simple form that passes to an ASPX page to watch a video. The ASPX page uses a hidden field from the form to load the correct video.
This works for me, but a couple other people are the error message because it appears the value isn't being passed. I'm assuming it's a setting in IE... Anyone seen this or know how to fix? OR a better idea?
Simple form on "yourdomain.org"
<form action="http://www.mydomain.org/WatchVideo/Default.aspx" method="post" enctype="multipart/form-data">
<input type="hidden" name="hidden" value="movie.flv" />
<input type="submit" name="submit" value="Watch Video" />
</form>
The ASPX page on "mydomain.org"
If Request.Form("hidden") IsNot Nothing Then
lit.Text = Request.Form("hidden")
Else
Response.Write("Not Authorized. Video Not Passed.")
End If
Sounds and loooks pretty straight forward. Not sure why the same version of IE would have different results. Any other thoughts on how to do this? I need to keep the "off site" coding simple and in HTML for non-technical folks.
Thanks.
It appears to be a setting inside of the browser. I couldn't narrow it down to a specific setting, but once we changed the "Internet" zone to medium from medium-high it began working. It has something to do with posting form data across domains.

Links from the menu are directing correctly but links like the one in the page below are SUDDENLY not.

I gave searched on this topic. I have tried reseting permalinks and deactivating/activating plugins. Neither seems to work. I have also tried changing the theme. Still nothing.
Any helpful suggestions are welcome
You have a problem with the form that does the redirect on that button. See below
<form method="link" action=" http://tazara.mwanawanga.com/?page_id=389">
<input type="submit" value="View fare charts and train timetables">
</form>
If you can see, theres a space in the action field of the form which will error the form's action and go to the root.
Try changing it for this:
<form method="link" action="http://tazara.mwanawanga.com/?page_id=389">
<input type="submit" value="View fare charts and train timetables">
</form>
The same will probably go for many other buttons on the site doing the same thing. I would personally recommend not using forms though and just creating a class which has the same styling as a form submit button and using a tags to link. It will be more search engine friendly and easier to use and maintain.
This has been really frustrating. I changed the action of my form in order to send it to a different webform for testing, but no matter what I do, it still sends it to the old webform. There is no mention of this webform anywhere in the code any longer, and if I run the initial page outside of visual studios, it directs to the correct webform, but for some reason visual studios continues to direct to the old one. Any possible ideas?
<form onSubmit="return validate()" method="post" name="form1"
action="http://localhost:65076/WebForm7.aspx">
<input type="submit" value="Calculate Risk" style="float:right">
</form>
This should send me to webform7.aspx, but it always sends me to webform1.aspx
EDIT: At this point, I've created a new html page, copied the contents of the one above, renamed the form to name="form2", and gotten it to direct correctly, but I'd still really like to know why I'm not being allowed to change my action.
in a content page of an asp.net web page, i would like to include the "paypal" button "Pay Now".
So, i've a master page, and a content page.
In my content page i copy-paste paypal code.
In particular i use a "modalpopupextender" to permit my user to buy the object.
The problem is... it not work.
So my hypotheses are:
I'm not sure, but i think i can't use a nested <form action>
If not the first, maybe i can't use a <form action> into a modal popup ?
someone can suggest me an "elegant" solutions to solve this ?
Thank you ...
EDIT: in particular, what i'm trying to do is to permit to sell from a website.
I've a master page, and a content page.
Obviously in master page i've the classical "form action" .
Then i'm gone to paypal and got this code: "
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<table>
<tr><td>
<input type="hidden" name="on0" value="Annuncio Premium">Annuncio Premium
</td></tr>
<tr><td>
<select name="os0">
<option value="Premium 1">Premium 1 €1,00</option>
</select>
</td></tr>
</table>
<input type="hidden" name="currency_code" value="EUR">
<input type="hidden" name="encrypted" value="-----BEGIN ">
<input type="image" src="https://www.paypal.com/it_IT/IT/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal - Il sistema di pagamento online più facile e sicuro!">
<img alt="" border="0" src="https://www.paypal.com/it_IT/i/scr/pixel.gif" width="1" height="1">
</form>
So i've pasted it into my content page ... as it... without changing.
In particular i've pasted it, into a panel, that will show whith a "modalpopupextender".
It works. But what it not work is when i click the paypal "Buy Now" button.
My web page don't redirect to paypal, modalpopup disappears and nothing happens.
I had this exact issue too and couldn't believe that PayPal had not provided some sort of solution for .NET developers!!
Here is how I solved it:
<asp:ImageButton ID="btnPayNow" runat="server" ImageUrl="myPayPalButton.jpg"
PostBackUrl="https://www.paypal.com/cgi-bin/webscr" OnClick="btnPayNow_Click"/>
Use an ImageButton or normal button and simply remove the form tags for the PayPal code, leave in the hidden input fields and the data will be posted to the PayPal url!
Nice and easy :)
Ps. The method 'btnPayNow_Click()' does nothing, signature exists but there is no logic in the code I have.
You are quite correct, in that you cannot nest <form>s.
Nor can you use the form action to create a popup - the action attribute is the url to which the form posts to.
You can, however, have many <form>s on the page, so long as they are not nested. Perhaps that will solve you issue.
Can you please describe exactly what you are trying to achieve? It is not clear from your question what the problem is.
If I understand the question correctly, you are trying to create a dynamic HTML popup window which contains a PayPal form. You are having problems because the popup contains a form, but the HTML for the popup is already contained within a form.
If the problem you are experiencing is what I described above, the solution is fairly simple. You need to move all of the HTML for the popup outside of the exiting form element. If you are using CSS to properly lay out your site, it should be possible to display your dynamic popup wherever you need to on the page using relative or absolute positioning. The HTML for the popup need not be contained within another form. It may also be possible (perhaps even necessary) to put the contents of the popup into an iframe, which can be submitted entirely independently from the rest of the page. The semantics of how your popup works would depend on how you need your page to function.
So, to be clear...it is not possible to nest form elements. However, it is also not necessary to accomplish your needs.
EDIT:
To improve the answer above in light of the updated question. You can have multiple content panels on a master page. It should be entirely possible to create another content panel that is outside of your form element in your master page...and place your modal popup inside of this alternative content panel. My above answer would then still apply, as you no longer have nested forms.
You are right in your first hypothese, you can't have nested form tags in a page.
You just have to put the code for the popup outside the form, you can have any number of forms in the page as long as they are not nested.
Dal's answer is correct! (not taking credit with my answer)
I had a similar issue in ASP.NET (4.0) when trying to submit data to SagePay (same as PayPal form posting). I was writing the form fields in dynamically using panels in the code-behind using
Dim Panel As New Panel
Panel.Controls.Add(New LiteralControl("My <input> controls HTML")) '1 control.add per <input> control.
MyDiv.Controls.Add(Panel)
I was writing the whole < form> dynamically also, so when it came to debugging I received no warnings regarding the issue that my entire Site.Master is within a - this is not visible from a .aspx page using the master as a template! It was quite frustrating... Until I read that you cannot have a nested < form>... There are only two alternatives to this:
1) move the form details outside the first that is within my Site.Master from the .aspx page itself. (I didn't like the idea of this, messy messy!)
2) create another control that is NOT a to post my data.
I chose the latter!
<asp:Button id="btn_payment" value="Proceed to Payment" Text="Proceed to Payment" runat="server" PostBackUrl="https://test.sagepay.com/gateway/service/vspform-register.vsp" />
The button posted to SagePay, took my dynamically generated fields (Called from the .aspx page) and as they were already within the from my Site.Master - all worked well! - I hope this helps anyone using dynamically generated HTML with forms.
I have a classic asp application. I want to post a contest form from that page to an Asp.Net form. The reason is that I want to use a lot of logic i have built into an Asp.Net page for validation before entering into the database and I don't know asp very well. Not to mention asp.Net being more secure.
What's the best way to accomplish this goal? My thoughts are as follows:
My asp Page:
<html>
<body>
<form action="/Contests/entry.aspx" method="post">
Name: <input type="text" name="fname" size="20" />
Last Name: <input type="text" name="lname" size="20" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
aspx page is running in a Virtual Directory and would handle anything posted to it.
Is this possible, or does aspx prevent this kind of thing?
I ( preferably ) don't want to create the form in aspx as my colleague wants to have control of the page and build the html himself and I don't want the hassle of constantly changing it.
Are there caveats I need to consider?
What roadblocks will I run into?
How do I access the Posted Form Values? Request.Form?
Yes it is possible. In general, a POST is a POST. So you can post from a PHP page to a .NET page if you wanted. You would access the Request.Form variables just as you do now. You will have to look at the ASP Classic page to see the names of the post items but in general, you can access them as if you had pasted from .NET page.
This can be done and works fine. You will access the Posted Form values as you said via Request.Form.
I think the biggest caveat is that you will need to handle invalid data in some way - typically with a webform the .aspx page would be displayed again with validation errors, but that would likely be inappropriate for your circumstance. Probably you will need to redirect them back to the .asp page with query string parameters indicating the failures and the page will need code allowing it to fill in the form fields with their previous values and display the error message.
How about calling an ASP.NET webservice from classic asp?

I am building a german payment provider into my site.
But when I click on "Submit", nothing happens. Can someone please help me? I think I've looked at it too much and I can't see the forest for the trees anymore...
<form method="post" action="https://www.sofortueberweisung.de/payment/start">
<input name="currency_id" type="hidden" value="EUR" />
<input name="reason_1" type="hidden" value="Zambuu" />
<input name="user_id" type="hidden" value="29593" />
<input name="project_id" type="hidden" value="80145" />
<input type="submit" value="Absenden" />
</form>
Okay, so it's a little bit unclear what I want, it seems:
I have a lot of asp-sites allready, and now I must send, however, the information that is given by the hidden inputs by post-method to the site "sofortüberweisung.de/payment/start".
However I can solve it, it's not nessecary, there is no need for a form-tag, if there is another solution (e.g. with the code behind).
So: How can I send a lot of post information (these here is only an exmaple, in the real site there are a lot more) with code and redirect it to the right site?
If the code you have provided is within a standard ASP.NET form, so that you have nested form tags, try the solutions provided to this Stack Overflow question.
If it is possible to have this page be a simple html form, that is another possible solution.
Your button needs to have the runat="server" attribute set and it might be worth doing the same on your form atttribute.
Also remember in asp.net webforms you can only have one form tag.
I've had this issue a couple of times before where when creating an HTML form inside an ASP.NET form tag, the inner form just wouldn't post out.
One solution for me was to adjust the ASP.NET form tag wrapper for that page (moving the close above the HTML tag).
Another (where I needed ASP.NET controls obove and below the HTML form) was to add an iframe, passing the parameters for the form post to the iframe URL. Using JavaScript, the iframe then used those parameters to post the form to a new window/the parent window. Probably better ways, but it worked for me.
