I have some html code that contains a form. When submitted it sends a post request to a server. The form has various inputs, each with a name and a value, however there are some inputs with the same name.
Here is an example of what I mean:
<form action="http://example.com" method="post">
<input name="name" value="val">
<input name="name" value="val">
<input type="submit">
</form>
First, I am confused as to how there can be two values of the same name. Please note that I have tried removing one of the instances of <input name="name" value="val"> however this returns an error so it seems that both instances are needed.
Second, I am trying to convert this to a python request using the request library.
I have the following request:
requests.get(url = URL, params = PARAMS).json()
Where PARAMS is a dictionary of the various inputs. For example:
PARAMS = {'name':"val"}
However, being a dictionary, I can't have multiple instances of the same value. How do I make this work? Thanks
If there are duplicated names then the values will be in an array with the name. The demo below sends to a live test server and the response is directed to an <iframe>
<form action="https://httpbin.org/post" method="post" target="response">
<input name="name" value="val">
<input name="name" value="val">
<input type="submit">
</form>
<iframe name='response'></iframe>
What you are looking for is to use input arrays. With them, you can have many inputs sharing the same name, and in the server side, the data will be treated as an array. So the HTML would be:
<form action="http://example.com" method="post">
<input name="name[]" value="val1">
<input name="name[]" value="val2">
<input type="submit">
</form>

I have a from with three possible inputs to submit and send through a seperate script that then generates JSON data.
The problem is however while two inputs are actual inputs = one email and one being a nummer. The third one is not a really traditional input.
<form action="{ url_for('handle_data') }}" method="POST">
<div class="form-group">
<label for="Speryear">SPER jaar</label>
<input class="form-control" type="number" value="2" name="Speryear" min=0 max=10 />
</div>
<div class="form-group">
<div class="form-group">
<label for="inputEmail">Verzendings mail</label>
<input class="form-control" type="email" name="inputEmail" required />
</div>
</div>
<div class="form-group">
<div class="url-panel">
<p> <b>Url:</b></p>
<p id="api-url" name="api-url"></p>
</div>
</div>
<button id="search" type="submit" class="btn-primary">
Aanvraag indienen</button>
</form>
#app.route('/handle_data', methods=['POST'])
def handle_data():
sper_year = request.form["Speryear"]
email = request.form["inputEmail"]
url = request.form["api-url"]
Requested_data = GIPOD_converter.main(url, sper_year, email)
return Requested_data
The third input is actually a paragraph which is dynamically based on the values of a second form (the primary from) for the data requests. According to this post here:
Sending data from a html non-input to Flask
HTML forms only send along tagged values to the remote endpoint when a "submit" input is pressed.
I have tried to make this paragraph a data input but the thing is this will break the javascript I have for that specific id. Aka a the URL part that I want cannot be generated in the input field. So can my code get the paragraph from this?
Edits done as per answer.
I think you should end the app route with:
return Requested_data
Also, you do not define correctly to the url form, i.e.:
url = request.form["api-url"]
Briefly, python Flask is the workbench of web hosting I use, and I am trying to create an input form that doesn't appear in your history.
This is my form html:
<form name="ViewWindow" action="/home/ViewWindow/ViewWindowResult/">
<input name="url" type="url" required="required" placeholder="URL Here">
<input type="submit" value="Go">
</form>
And this is the python code working with the input url:
#web_site.route('/home/ViewWindow/ViewWindowResult/', methods=('GET', 'POST'))
def ViewWindowResult():
urlboi = request.values.get('url')
response = urllibrequest.urlopen(url) # import urllib.request as urllibrequest
htmlBytes = response.read()
htmlstr = htmlBytes.decode("utf8")
return html("ViewWindowResult.html", value=htmlstr)
My goal is to get here; /home/ViewWindow/ViewWindow/ViewWindowResult/,
but I end up getting here when I input "https://www.w3schools.com/tags/"; /home/ViewWindow/ViewWindowResult/?url=https%3A%2F%2Fwww.w3schools.com%2Ftags%2F
Why does Flask put my inputs in the url string? I do not intend to do this anywhere.
Edit: You can check this out by going to https://sm--supermechm500.repl.co/home/ViewWindow/
Try specifying the form method like so:
<form name="ViewWindow" action="/home/ViewWindow/ViewWindowResult/" method="post">
<input name="url" type="url" required="required" placeholder="URL Here">
<input type="submit" value="Go">
</form>
use post method like
<form name="ViewWindow" action="/home/ViewWindow/ViewWindowResult/" method="post">
<input name="url" type="url" required="required" placeholder="URL Here">
<input type="submit" value="Go">
</form
and then you python code is
#web_site.route('/home/ViewWindow/ViewWindowResult/', methods=('GET', 'POST'))
def ViewWindowResult():
input=request.form['url']
#write your code here
return(input)
its working for me it will print the url which same you entered
I've the following HTML code:
<html>
<form action="index.php" method="post">
Enter Input:
<input type="text" class="textbox" name="usn" id="usn" required />
<input class="buttongo" type="submit" value="Go" />
<input type="hidden" name="task" value="getResult"/>
</form>
</html>
I want to write a python script, which executes the above HTML, passing a value parameter to the first input statement to the above HTML. That is,
<html>
<form action="index.php" method="post">
Enter Input:
<input type="text" class="textbox" name="usn" id="usn" value="FromPython" />
<input class="buttongo" type="submit" value="Go" />
<input type="hidden" name="task" value="getResult"/>
</form>
</html>
Further, is there a way in which I can directly send the value to index.php and get the response?
(P.S.: I want to loop the value from 0 to 100 and save the response generated in a file)
Why don't you send the request using python ? You can send the requests inside a loop and pass the parameters you want.
Making requests with the requests module
sample code :
import requests
for i in range(101):
payload = {'usn': i}
response = requests.post("index.php", data=payload)
# do something with response
Use urllib module, documentation at: https://docs.python.org/2/library/urllib.html
As described in the link, this module provides a high-level interface for fetching data across the World Wide Web.
Using Django I'm looking for a good way to get the input values and names of type=hidden from a template HTML. I understand the request.POST.getlist method would return a list of all inputs with the same name value. But I actually need to get all the names as well as the values. i.e.,
HTML Code:
<fieldset class="submit">
<input type="hidden" name="testName" value="0" id="processed-input" />
<input type="submit" name="submit" value="Rotate" class="submit" />
</fieldset>
And I need to get a list of related names and values. For this case, testName:0.
Any help would be appreciated! Thanks!
That's what request.POST is: a mapping of all names to values.
I have the following template form, containing several variables.
<form action="https://me.s3.amazonaws.com/" method="post" enctype='multipart/form-data' class="upload-form">
<input type="hidden" name="key" value="videos/{{filename}}">
<input type="hidden" name="AWSAccessKeyId" value="{{access_key}}">
<input type="hidden" name="acl" value="public-read">
<input type="hidden" name="policy" value="{{policy}}">
<input type="hidden" name="signature" value="{{signature}}">
<input type="hidden" name="Content-Type" value="{{content_type}}">
<input name="file" type="file">
<input type="submit" value="Upload" name="upload">
</form>
However, as soon as the submit button is hit, the form is sent to amazon, and I'm not able to pass it variables. This is what I've been trying to do, unsuccessfully --
if 'upload' in request.POST:
policy = base64.b64encode(...)
signature = base64.b64encode(
hmac.new('secret_key', policy, sha).digest())
file = request.POST['files']
filename=file.name
content_type=mimetypes.guess_type(filename)[0]
What do I need to do to pass the variables to the form after the POST request but BEFORE amazon processes the form? Thank you.
You should change your form's action to your django view and in your view you can re-post to https://me.s3.amazonaws.com/:
In your template
<form action="http://mywebsite/upload" method="post" ...
In your view.py:
def upload(request):
# Your treatment here.
# Post the data to amazon S3.
urllib2.urlopen("https://me.s3.amazonaws.com/", your_data)
...
You could change the form to POST to one of your own views, then do your post-processing in your view, and then within your view code, issue a POST to Amazon with the correct values using, say, urllib2 or similar.
