I have the following client side code:
<form action="PhotoStore.aspx" id="form1" method="post" enctype="multipart/form-data">
<div>
<input type="file" id="file"/>
<input type="submit" />
</div>
</form>
With this client side code, how will I access the uploaded file in Photostore.aspx? Request.Files is having a count = 0 :( .? Whats going wrong?
You need to put a name on the input field, or it won't be included in the form data:
<input type="file" name="file"/>
What about
Page.Request.Form["file"]

I want to upload <img> tag src in my spring mvc. I have already tried to upload img using input file method. But is it possible to upload a img src to spring controller?
<form method="POST" action="<c:url value='/upload' />"
enctype="multipart/form-data">
Please select a file to upload : <input type="file" name="file" />
<input type="submit" value="upload" />
</form>
I have already uploaded the image using file input tag.
<form method="POST" action="<c:url value='/upload' />"
enctype="multipart/form-data">
Please select a file to upload : <img src="demo.png" />
<input type="submit" value="upload" />
</form>
Is it possible to do the upload using img tag without using file input tag.
You need to insert your data to form to be able to submit the data to a database or other uses.
Since <img src="demo.png" /> is just a static html code, form can´t get the data from that.
What you can do is to pass the src to <input type="file" name="file" />
We are hosting a PURL site and the variable is at the end: http://mywebpage.com/first.last
Now the client wants a static web page where you go and enter a first and last, then on submit it goes to out PURL site.
Tried this with straight html but it's not going to work. On to ASP.
New to ASP and I'm trying to have a form that has 2 fields, first, last in a link. Here is the form concept:
<form id="form1" name="form1" method="post">
<p>
<label for="1">First Name:</label>
<input type="text" name="first" id="first" />
<label for="2">Last Name:</label>
<input type="text" name="last" id="last" />
</p>
<p><input type="submit" name="3" id="3" onclick="window.open('http://mywebpage.com/first=val1&.&last=val2')"/>
</p>
</form>
Any help to put me on the right tracks would be extremely welcome at this point.
Thank you,
Ed
Try this:
<form id="form1" name="form1" method="GET" action="http://mywebpage.com/" >
Then do a normal submit without onclick and window.open.
action will submit form to that URL, and method="GET" will pass form parameters in a query string.
I am trying to put a button on my shiny app which calls out external website though a form/post request. The input values will change but here is a real example.
Example:
<form action="http://toppgene.cchmc.org/CheckInput.action" method="post">
<input type="hidden" name="query" value="TOPPFUN">
<input type="hidden" id="type" name="type" value="HGNC">
<input type="hidden" name="training_set" id="training_set" value="EGFR">
<input type="submit" class="mybutton">
</form>
PS: cross posted on shiny-discuss google group link
Thanks!

Basically I want to place a url in the form action method.
The ltlUrl.text value is added on the server side in pageLoad.
How do i use the ltlUrl as the action method?
<form action="<%# ltlurl.text%>" enctype="multipart/form-data">
<input type="text" name="title" value="test" />
<input type="file" name="file" />
<input type="submit" />
</form>
Since you are populating the text control on code behind, you can simply do this:
this.Page.Form.Action = "http://someour";
I believe the VB.NET syntax would be:
Me.Page.Form.Action = "http://someurl"
All the examples I can find are in Visual Basic, but I am using C#.
I want to get the data that is in a textbox in a form.
My code so far:
<form action="login.aspx" method="get">
<p>Username: <input type="text" name="username" /></p>
<p>Password: <input type="text" name="password" /></p>
<input type="submit" value="Submit" />
</form>
So what could I do? Because I keep getting told to do this:
Dim UserName
UserName = Request.Form("UserName")
But it doesn't work in C#.
Don't need to do that on asp.net; simply change your markup like so:
<form action="login.aspx" method="post" runat="server">
<p>Username: <input type="text" name="username" runat="server" id="txtUsername" /></p>
<p>Password: <input type="text" name="password" runat="server" id="txtPassword"/></p>
<input type="submit" value="Submit" />
</form>
And on code behind:
string UserName= txtUsername.Value;
And yes, Shawn also caught a good one, you should use POST.
Your method should be POST.
<form action="login.aspx" method="post">
The sample code you posted is vb.net. C# has it's own syntax and keywords.
to get the value you can use the following (not an optimal solution for webforms)
string userName = Request.Form["UserName"];
I would suggest going through some c# tutorials to get a handle on the language. Here's the first one i found http://www.csharp-station.com/Tutorial.aspx
