I'd like to pass additional argument next (it should be endpoint) to the request when submitting the form. I've tried:
<form method="post" action="" next="/apply"> but it doesn't work.
Later when receiving the form I just need to read it from request.args. How to do it correctly?
You can use a hidden form field.
<form method="post" action="">
<input type="hidden" name="next" value="/apply">
<!-- the rest of your form code -->
In your Flask function:
next = request.form.get('next')

I have been given the following POST instruction, and I am trying to translate it into httr:
<form method="POST" action="https://this.website.com/foldername>
<input type="hidden" name="ExternalAction" value="AgetAscii">
File Type <input type="text" name="filechar" value="0">
<input type="submit" value="Click here to Retrieve the File"/>
</form>
I am having trouble getting the right syntax for httr. I would welcome suggestions. The initial input type, name and value seem straight forward, but I don't see how I bring the File Type arguments into httr, nor am I confident I am handling the final "submit" and value items properly.
I'd welcome suggestions.
Many thanks
If I paste that example html into an local html file and substitute the action to be http://bin.org/post like so:
<form method="POST" action="http://httpbin.org/post">
<input type="hidden" name="ExternalAction" value="AgetAscii">
File Type <input type="text" name="filechar" value="0">
<input type="submit" value="Click here to Retrieve the File"/>
</form>
Then the only form data reported back by httpbin.org as having been received are for ExternalAction and filechar. Therefore, to send this data via httr::POST() you would do:
library(httr)
action <- "https://this.website.com/foldername"
body <- list(ExternalAction = "AgetAscii",
filechar = "0")
POST(url = action, body = body)
I have a simple problem yet it seems impossible to solve in AMP!!
I have a simple form with an input and a submit button like this:
<form id="myform">
<input type="text" id="srchInput"/>
<button type="submit">Submit</button>
</form>
All I want is to be able to concat a static url to the input value and redirect the page to the result, when the form is submitted.
For instance if the user inputs: "Hello" and submits the form, I would like to redirect him to a page like "MY/STATIC/URL/Hello".
Is there any way to achieve this in amp?
One way of doing this is by setting the AMP-Redirect-To header in the response (See AMP-form-redirection). Send the user input on form submission, and then generate your desired url from your API endpoint and set AMP-Redirect-To header in your response to the generated URL.
Another way of doing it would be by using navigateTo(url=STRING) action (See AMP Actions & Events) on for the form submit event. In this case you have to store the value in input to a state by using events like input-throttled, and then use url substitution in the navigateTo url string to append amp-state value.
The first method is guaranteed to work.
The second method should work in theory, but I was unable to figure out how to get AMP-STATE value by url substitution. The code for the same should be something like:
<form id="myform" on="submit:AMP.navigateTo(url="MY/STATIC/URL/AMP_STATE(endValue)>")">
<input type="text" id="srchInput" on="input-throttled:AMP.setState({ endValue : event.value })" />
<button type="submit"> Submit </button>
</form>
If you can figure out how to substitute amp-state value to the url this should work. Let me know if it helped.
The easiest way to do this is via a GET action:
<head>
...
<script async custom-element="amp-form" src="https://cdn.ampproject.org/v0/amp-form-0.1.js"></script>
</head>
<body>
<form method="GET" action="MY/STATIC/URL" target="_top">
<input type="text" id="srchInput" name="srcInput" value="test">
<button type="submit">Submit</button>
</form>
</body>
The form submit will navigate to /MY/STATIC/URL?srcInput=test.
I have a problem while accessing the page parameter in thymeleaf.
Please see my below code :
<input type="hidden" name="resetKey" th:value="${param.key}"/>
I am trying to access parameter key from query string and send it as hidden parameter to the server.
After page loads, it is displayed like below :
<input type="hidden" name="key" value="[Ljava.lang.String;#b1fd0f9">
I want to send the key back to the server when the form is submitted.
You are trying to print a multi-value, a String array. To print the first value:
<input type="hidden" name="resetKey" th:value="${param.key[0]}"/>
Or this should work too:
<input type="hidden" name="resetKey" th:value="${#request.getParameter('key')}"/>

i have a html form into my database.
In this form i have a value which contains a Viewbag,
for example value="#Viewbag.MyVariable"
In my view when i try to receive my form all works fine,
but my problem is that the Viewbag value are not converting
to the value which comes from my controller.
any ideia how to resolve this ?
my code:
View:
#Html.Raw(p.Form)
My form in my database looks like:
<form action="/MyController/MyAction" method="post">
<input type="hidden" name="num" value="#ViewBag.num" />
....
....
....
</form>
What i have try to do was with:
Stringbuilder a=new Stringbuilder;
#Html.Raw(a.To.String())
Your code should technically work, if you are using MVC you could try
#MvcHtmlString.Create(p.Form);
I found a solution and now i solved it.
what i have done:
in my form the only part which are different from the others
forms are the dropdownlists.
i only put the part from <select> to </select> in my
database. (only the dynamically part of my form)
in my view i have write my form and only insert the variable
which comes from my controller to insert the data from my
database on the right part in my form.
here is the code:
<form action="/MyController/MyAction" method="post">
<input type="hidden" name="num" value="#ViewBag.num" />
#MvcHtmlString.Create(p.Form);
<button type="submit" name="submit" id="submit">OK</button>
</form>
So i have never more the problem with the variables to be
converted, because the variables are still the same
I have following form
<form id="myForm" action="/Problems/Post" method="post" enctype="multipart/form-data">
<input type="text" id="problemSubject" name="problemSubject" />
<input type="file" id="uploadFile" name="uploadFile"/>
<textarea rows="" cols="" class="form-textarea" id="problemDescription" name="problemDescription"></textarea>
</form>
I have to submit form to controller method(which i have done), but it should be first validated i.e. it should not contain empty fields. What i want is that "a message should appear telling that field is blank". How this can be done. Please help me. Thanks.
Take a look at some of the samples. (http://www.asp.net/mvc/tutorials/older-versions/javascript/creating-a-mvc-3-application-with-razor-and-unobtrusive-javascript)
Essentially you can validate on client side and on server side, which you should do both.
It is very easy to do validation in asp.net mvc3. Look at some tutorials like above.
Or this one: http://www.codeproject.com/Articles/249452/ASP-NET-MVC3-Validation-Basic
u can use server side validation controls...
plz hv a look [link]http://msdn.microsoft.com/en-us/library/aa479013.aspx
or use the jquery gven below--->
function callOnload(){
if($('#problemSubject').val() == '')
alert('fill the values');
if($('#uploadFile').val() == '')
alert('fill the values');
}
