can some one help me please.
how can I add 1 more input to YUI POST CONNECTION
Here is the tutorial: http://developer.yahoo.com/yui/examples/connection/post.html
And the default sample form is: <form><input type="button" value="Send a POST Request" onClick="makeRequest();"></form>
How can I add one more input like that:
<form>
<input type="text" name="username">
<input type="button" value="Send a POST Request" onClick="makeRequest();">
</form>
I want to send username input request too.
Thank you !!
The example you reference builds the POST request body manually. While you can certainly do this, you might find it easier to use the setForm method of the Connection Manager (example here). It will include all the form fields and take care of the URL encoding for you.

The explanation below is big, but the question is really simple.
I'm doing a simple form project in https://www.theodinproject.com/paths/full-stack-ruby-on-rails/courses/ruby-on-rails/lessons/forms.
The first part where I am, I need to build a form manually - so that I can see how Rails does a lot for me when I use its helper methods.
I'm stuck in this point:
Specify the method and the action attributes in your tag (use $ rails routes to see which HTTP method and path are being expected based on the resource you created).
The routes.rb file looks like this:
resources :users, only: [:create, :new]
I don't know how to determine which method should I use for the form - post or get.
I don't know how to determine which action path I should use.
I've gone into the internet, Rails guides and etc, and have solved the other topics so far, but for this one I can't get through it.
My form so far:
<form action='/create' method="post" accept-charset="UTF-8">
<label for="username"></label>
<input type="text" id="username" name="username"><br>
<label for="email"></label>
<input type="text" id="email" name="email"><br>
<label for="password"></label>
<input type="text" id="password" name="password"><br>
<input type="submit" id="submit" value="Submit" >
</form>
Once I run it in the server and then submit the form - which I did - I should get:
"Submit your form and view the server output. Oops, we don’t have the right CSRF authenticity token (ActionController::InvalidAuthenticityToken) to protect against cross site scripting attacks and form hijacking. If you do not get an error, you used the wrong method from step 1."
Yes, Rails is smart) When u are sending the request to your server, Rails must know from where this request is coming. In short, if your form sending the CSRF token then Rails understand that u send this request, otherwise someone else on your behalf (CSRF attack).
To fix this bug u need to set <%= form_authenticity_token %> in your .erb view. It will generate this input that is below
<input type="hidden" name="authenticity_token" value="your_token_generate_by_rails">
Or for your testing purposes, u can use this in your controller which is processing your request. But never use it in future if you are don't know what are u doing)
skip_before_action :verify_authenticity_token
Hi there fellow Odin student!
It looks like you're doing this lesson. Me too!
It sounds like you're asking about what value to use with action attribute in the form.
When I created a form using the Rails formHelper methods, I inspected the HTML that Rails created when I was previewing the app/website (rails s). By opening up the Developer tools (F12 key, or right click the mouse and choose inspect)I was able to see that the form Rails created had an action equal to the name of the resource, with a forward slash in front of it.
So for your example, the resource created is "users". So the action attribute would be /users
to be complete, the solution would be something like: <form action="/users"...
Hope this helps!
I try to move my text analyzer from console to web form.
I have simple form like this:
<form action="/">
<textarea name="str"></textarea>
<input type="submit">
</form>
Generally I could have very long texts for analysis inside of textarea. When I submit the form I get the following from thin:
Invalid request: Header longer than allowed
So the question is what is the proper approach to send long texts to server? Uploading files or filling links to url are not the option unfortunately.
By default the method of a form is GET, which has a limit on the number of characters allowed. (The limit depends on server and client, see for instance this answer, which specifies that usually it is 8KB).
You should use instead a method POST, which has much larger limit, around 2GB.
<form action="/" method="POST">
<textarea name="str"></textarea>
<input type="submit">
</form>
I have an URL. There is a form in that URL and I know it's name and the form action.
E.g:
url:
www.abc.com/123.html
form:
<form action="POST.php" method="post" name="form">
<input id="id" name="name" type="text">
</form>
My question is how do I post this form and get the response? I have tried several answers but they didn't work well. Any programming language is fine.
this can be done in PHP.
see this Submitting form to remote server.
I'm making a single web app.
I have a form with a POST method and an action value equal to "/login".
<form action="/login" method="POST">
<label for="mail">Email</label><input name="log" id="mail" type="text">
<label for="pass">Pass</label><input name="pass" id="pass" type="text">
<input type="submit">
When the submit button is press, server get the form, then return to the index page.
But, in the address bar, I have "local:5050/login" and would have "local:5050".
Can I remove the "login" mention ?
Since you are making a SPA, you will not want to have the POST method of the form actually complete. Generally this is done in dart by attaching a listener on the form element, within that listener you would then do a couple of things:
1) Cancel the default action (Also see: How do I prevent an on.submit event from changing/reloading the page?)
2) Get the values you're interested in from the form (or potentially take the entire form itself)
3) Send the values via an AJAX request to the server and listen for the response from the server to verify it was valid etc.
See the Dart tutorials on forms for more information on accomplishing the other steps.
Say I were to post to a site using www.mysite.com?user=myuser does that simulate the submit button that is associated with that form? If so, what happens if there are a number of submit buttons in the form?
Also, if that button's html is like so <input name="button" class="button" type="button" value="Save" onclick="javascript: submit()" disabled> with the "disabled" attribute, does that mean I can't POST www.mysite.com?user=myuser/won't work?
<form name="Form" method="post" action="/thisAction.do">
<input type="text" name="inquiryNo" maxlength="11" value="" onkeyup="javascript: checkNo()">
<input name="buttonInquire" class="button" value="Inquire" onclick="javascript: submitInquire()" type="button">
<!--Then comes a number of other inputs-->
<input.../>
<input.../>
<input.../>
<input name="modify" class="button" type="button" value="Save"
onclick="javascript: submitModify()" disabled>
</form>
This is some sample code as it's work stuff which I am not allowed to share. So when I use the inquire action a new account successfully loads up and the details are presented on the page. The modify action is meant to 'modify' those details but it just returns the same details displayed on the page. I get no sort of feedback from anything.
You can POST to a URL with a query string (the stuff after the ?), and since you say you're using urllib2 with a data argument, that's what happens. The server can then read both the POST data and the query string and do whatever it wants, though most of the time they're merged together or the query string is ignored entirely.
disabled only stops you from clicking the button in the browser (and even then, you can just un-disable it with a tool like Firebug). You can POST whatever you want to any URL you want; HTML can't stop you, though the server can still give you an error if it wants.
I think your problem is that "inquire" is the default action, and something's wrong with your POST. So no matter what you send, the server isn't recognizing it and is falling back to "inquire".
It looks like the form is intended to send modify=Save. Can you post the Python code you're actually running?
No, what you actually typed in is a GET method.
There are 2 ways of submitting data: POST AND GET.
Post is by submitting data by using a form in a webpage that posts to another on the background, while GET is setting the data in the url itself like user=myuser.
Most of the times using a GET method (url query string) will not work if the web programmer actually is checking for a POST method. The same happens if the programmer is waiting for a GET request and you actually POST it.
However there is a php var called REQUEST which will work with GET and POST.
I'm no professional in PHP but because you had no answers at the moment I tried my best to explain it. Hopefully some expert will come along and explain it properly.
You edited your question while I was replying so you need someone to answer you on your second question.
