Form with different target urls to send the POST to - html

I have one view displaying a form. Now, depending on the button the user chooses, I want to have the data processed in a different way. These "different ways" correspond with different views that I want the POST request go to.
Please help me building a form with multiple buttons leading to different urls/views.
<form action="/your-name/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Process form with view ONE">
<input type="submit" value="Process form with view TWO">
<input type="submit" value="Process form with view THREE">
</form>
My problem here is that the action attribute of the form tag defines where this POST request is going to. How can I change that target url via multiple buttons?
I know I could also handle this logic on the server-side. But the question is: Do I have to? If not, please show me the way

you can use ajax with onclick attribute. post_url as an argument like this
<form method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Process form with view ONE" onclick='testFun(url_one)'>
<input type="submit" value="Process form with view TWO" onclick='testFun(url_two)'>
<input type="submit" value="Process form with view THREE" onclick='testFun(url_three)'>
</form>

To handle this on the frontend without even using ajax, you can use JavaScript to change the action URL of the form based on which button is clicked before submitting the form.
Slight change on your HTML code
<form method="post" id="my-form">
{% csrf_token %}
{{ form }}
<input type="submit" id="view1" value="Process form with view ONE">
<input type="submit" id="view2" value="Process form with view TWO">
<input type="submit" id="view3" value="Process form with view THREE">
</form>
JavaScript for handling the redirection of the form based the button clicked
const form = document.getElementById('my-form');
const button1 = document.getElementById('view1');
const button2 = document.getElementById('view2');
const button3 = document.getElementById('view3');
button1.addEventListener('click', () => {
form.action = '/view1/';
});
button2.addEventListener('click', () => {
form.action = '/view2/';
});
button3.addEventListener('click', () => {
form.action = '/view3/';
});
// Submit the form
form.submit();
Note: You can use jQuery for better code optimization

Django, How to pass HTML form values to URL upon form submission?

The project have url as follows,
path('post/<str:state>/',SearchView.as_view(),name='search-data')
I have a HTML form, upon filling and submitting it supposed to pass filled form data to URL.
<form action={% url 'search-data'%} method="get" >
{% csrf_token %}
<input type="text" name="fname">
But it does not work as supposed to be.
When form submitted it gives below URL
http://127.0.0.1:8000/%7Burl?csrfmiddlewaretoken=2RZfZ4cxLB...
You don't have to pass <str:state> argument in your urlpatterns just pass path('post/search',SearchView.as_view(),name='search-data') or whatever you want but problem is when you pass an argument like this post/<str:state>/ than you have to specify that in your form action also
like this {% url 'search-data' state %} initialy you don't have any state so that's why you have to get the state name from your form so finnaly your code look like this
<form action={% url 'search-data'%} method="get" >
{% csrf_token %}
<input type="text" name="fname">
<input type="submit" value="search">
</form>
and than in your views you've to get it from request.GET method like this
def search(request):
state = request.GET.get('fname', None)
.... do whatever you want
return response_or_data

What does <form action = ""> mean ? Many videos I saw assign the action attribute an empty string and I have no idea what it means

<form method="POST" action="">
{% csrf_token %}
{{ form.as_p }}
<input class="button" type="submit" value="Submit">
</form>
What will happen after I click the Submit button?
Syntax
<form action="URL">
the URL shows Where to send the form-data when the form is submitted.
Example
On submit, send the form-data to a file named "process_input.php" (to process the input):
<form action="/process_input.php" method="get">
<input type="text" id="name" name="name">
</form>

how get to next form after submit but it's on same page

I want to make a survey based on forms, in which I try to get the new (next) form after a submit on the first form like below.
<form id="pass" action="form.html" method="get">
---some code for users to select answers--
<button type="submit" form="nextpass" value="next">
</form>
<form id="nextpass" action="form.html" method="get">
Both forms are displayed on the same page, but when I press the next button, I get the error "cannot get /".
Simplest way is to give each submit button a unique name. Then check if it was submitted, and process accordingly.
<form id="form_1" action="" method="post">
<input type="submit" name="submit_1" value="Submit" />
</form>
<form id="form_2" action="" method="post">
<input type="submit" name="submit_2" value="Submit" />
</form>
<?php
if( $_POST['submit_1'] ) {
// Do stuff
//hide form 1
echo "<style>#form_1{display:none}</style>";
}
else if( $_POST['submit_2'] ) {
// Do stuff
}
?>

get input form not as variable but as url

I am building a webservice so people can search into the database. Lets say I have users and companies. Each user and company can be found thought their id. So if you search myurl/users/<id> you get information of that user, on the other hand if you search company/ you get information of that company.
For this I have created two simple input texts (one for users and another for companies) where people can type the <id>. My problem is that when I get the value from the input text I get this myrul/users?<id> and not myurl/users/id. I tried to hardcode the slash but then I get myrul/users/?<id>.
So my question is how can I get input text as a url and not as a variable.
I am using flask so my html has jinja2 code like this:
<!-- USER id -->
<form method='GET' action={{url_for('get_info_by_id', type_collection='user')}}>
<input type="text" name="my_id"/><input type="submit" value="Go">
</form>
<!-- COMPANY id-->
<form method='GET' action={{url_for('get_info_by_id', type_collection='company')}}>
<input type="text" name="my_id"/><input type="submit" value="Go">
</form>
In my python script (flask)
#app.route('myurl/<type_collection>/<my_id>')
get_info_by_id(type_collection,my_id):
# search into the database and return info about that id
As #dirn suggested in the commentary, I made it through JavaScript, here is the code if someone else is also interested:
HTML:
<!-- USER id -->
<form method='GET' class="search" id="user" action="">
<input type="text" name="my_id"/><input type="submit" value="Go">
</form>
<!-- COMPANY id-->
<form method='GET' class="search" id="company" action="">
<input type="text" name="my_id"/><input type="submit" value="Go">
</form>
JS:
$(".search").submit(function( event ){
event.preventDefault();
var my_id = $(this).find(":input").val();
url = 'myurl/'+ $(this).attr("id") + '/' + my_id;
window.location.href = url;
});
python (flask)
#app.route('myurl/<type_collection>/<my_id>')
get_info_by_id(type_collection,my_id):
# search into the database and return info about that id
Is there a reason you cannot use the variable, or are you just trying to get it into a URL so that you can do your search? I went out on a limb and assumed you just want the form and database search to work, so try the following out.
Adjust your route like so:
#app.route('myurl/<type_collection>/')
def findAllTheThings():
if not request.form['my_id']: # Just check if a specific entity is chosen
return render_template('YourTemplateHere') # If no entity, then render form
entity_id = request.form['my_id']
get_info_by_id(type_collection, entity_id):
# search into the database and return info about that id
Now adjust the template as follows:
<!-- USER id -->
<form method='GET' action={{url_for('findAllTheThings', type_collection='user')}}>
<input type="text" name="my_id"/><input type="submit" value="Go">
</form>
<!-- COMPANY id-->
<form method='GET' action={{url_for('findAllTheThings', type_collection='company')}}>
<input type="text" name="my_id"/><input type="submit" value="Go">
</form>
Now, if no entity has been selected you'll just render the form. You can throw in a flash to let them know they need to select a specific ID, or just let them figure it out. If an entity has been selected, you will call the fucntion correctly.

Two submit buttons in one form

I have two submit buttons in a form. How do I determine which one was hit serverside?
Solution 1:
Give each input a different value and keep the same name:
<input type="submit" name="action" value="Update" />
<input type="submit" name="action" value="Delete" />
Then in the code check to see which was triggered:
if ($_POST['action'] == 'Update') {
//action for update here
} else if ($_POST['action'] == 'Delete') {
//action for delete
} else {
//invalid action!
}
The problem with that is you tie your logic to the user-visible text within the input.
Solution 2:
Give each one a unique name and check the $_POST for the existence of that input:
<input type="submit" name="update_button" value="Update" />
<input type="submit" name="delete_button" value="Delete" />
And in the code:
if (isset($_POST['update_button'])) {
//update action
} else if (isset($_POST['delete_button'])) {
//delete action
} else {
//no button pressed
}
If you give each one a name, the clicked one will be sent through as any other input.
<input type="submit" name="button_1" value="Click me">
There’s a new HTML5 approach to this, the formaction attribute:
<button type="submit" formaction="/action_one">First action</button>
<button type="submit" formaction="/action_two">Second action</button>
Apparently this does not work in Internet Explorer 9 and earlier, but for other browsers you should be fine (see: w3schools.com HTML <button> formaction Attribute).
Personally, I generally use JavaScript to submit forms remotely (for faster perceived feedback) with this approach as backup. Between the two, the only people not covered are Internet Explorer before version 9 with JavaScript disabled.
Of course, this may be inappropriate if you’re basically taking the same action server-side regardless of which button was pushed, but often if there are two user-side actions available then they will map to two server-side actions as well.
As noted by Pascal_dher in the comments, this attribute is also available on the <input> tag as well.
An even better solution consists of using button tags to submit the form:
<form>
...
<button type="submit" name="action" value="update">Update</button>
<button type="submit" name="action" value="delete">Delete</button>
</form>
The HTML inside the button (e.g. ..>Update<.. is what is seen by the user; because there is HTML provided, the value is not user-visible; it is only sent to server. This way there is no inconvenience with internationalization and multiple display languages (in the former solution, the label of the button is also the value sent to the server).
This is extremely easy to test:
<form action="" method="get">
<input type="submit" name="sb" value="One">
<input type="submit" name="sb" value="Two">
<input type="submit" name="sb" value="Three">
</form>
Just put that in an HTML page, click the buttons, and look at the URL.
Use the formaction HTML attribute (5th line):
<form action="/action_page.php" method="get">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
<button type="submit">Submit</button><br>
<button type="submit" formaction="/action_page2.php">Submit to another page</button>
</form>
<form>
<input type="submit" value="Submit to a" formaction="/submit/a">
<input type="submit" value="submit to b" formaction="/submit/b">
</form>
The best way to deal with multiple submit buttons is using a switch case in the server script
<form action="demo_form.php" method="get">
Choose your favorite subject:
<button name="subject" type="submit" value="html">HTML</button>
<button name="subject" type="submit" value="css">CSS</button>
<button name="subject" type="submit" value="javascript">JavaScript</button>
<button name="subject" type="submit" value="jquery">jQuery</button>
</form>
Server code/server script - where you are submitting the form:
File demo_form.php
<?php
switch($_REQUEST['subject']) {
case 'html': // Action for HTML here
break;
case 'css': // Action for CSS here
break;
case 'javascript': // Action for JavaScript here
break;
case 'jquery': // Action for jQuery here
break;
}
?>

Maybe the suggested solutions here worked in 2009, but I’ve tested all of this upvoted answers and nobody is working in any browsers.
The only solution I found working was this (but it's a bit ugly to use I think):
<form method="post" name="form">
<input type="submit" value="dosomething" onclick="javascript: form.action='actionurl1';"/>
<input type="submit" value="dosomethingelse" onclick="javascript: form.action='actionurl2';"/>
</form>
You formaction for multiple submit buttons in one form
example:
<input type="submit" name="" class="btn action_bg btn-sm loadGif" value="Add Address" title="" formaction="/addAddress">
<input type="submit" name="" class="btn action_bg btn-sm loadGif" value="update Address" title="" formaction="/updateAddress">
An HTML example to send a different form action on different button clicks:
<form action="/login" method="POST">
<input type="text" name="username" value="your_username" />
<input type="password" name="password" value="your_password" />
<button type="submit">Login</button>
<button type="submit" formaction="/users" formmethod="POST">Add User</button>
</form>
The same form is being used to add a new user and login user.
Define name as array.
<form action='' method=POST>
(...) some input fields (...)
<input type=submit name=submit[save] value=Save>
<input type=submit name=submit[delete] value=Delete>
</form>
Example server code (PHP):
if (isset($_POST["submit"])) {
$sub = $_POST["submit"];
if (isset($sub["save"])) {
// Save something;
} elseif (isset($sub["delete"])) {
// Delete something
}
}
elseif very important, because both will be parsed if not.
Since you didn't specify what server-side scripting method you're using, I'll give you an example that works for Python, using CherryPy (although it may be useful for other contexts, too):
<button type="submit" name="register">Create a new account</button>
<button type="submit" name="login">Log into your account</button>
Rather than using the value to determine which button was pressed, you can use the name (with the <button> tag instead of <input>). That way, if your buttons happen to have the same text, it won't cause problems. The names of all form items, including buttons, are sent as part of the URL.
In CherryPy, each of those is an argument for a method that does the server-side code. So, if your method just has **kwargs for its parameter list (instead of tediously typing out every single name of each form item) then you can check to see which button was pressed like this:
if "register" in kwargs:
pass # Do the register code
elif "login" in kwargs:
pass # Do the login code
<form method="post">
<input type="hidden" name="id" value="'.$id.'" readonly="readonly"/>'; // Any value to post PHP
<input type='submit' name='update' value='update' formAction='updateCars.php'/>
<input type='submit' name='delete' value='delete' formAction='sqlDelete.php'/>
</form>
I think you should be able to read the name/value in your GET array. I think that the button that wasn't clicked won't appear in that list.
You can also do it like this (I think it's very convenient if you have N inputs).
<input type="submit" name="row[456]" value="something">
<input type="submit" name="row[123]" value="something">
<input type="submit" name="row[789]" value="something">
A common use case would be using different ids from a database for each button, so you could later know in the server which row was clicked.
In the server side (PHP in this example) you can read "row" as an array to get the id.
$_POST['row'] will be an array with just one element, in the form [ id => value ] (for example: [ '123' => 'something' ]).
So, in order to get the clicked id, you do:
$index = key($_POST['row']);
key
As a note, if you have multiple submit buttons and you hit return (ENTER key), on the keyboard the default button value would be of the first button on the DOM.
Example:
<form>
<input type="text" name="foo" value="bar">
<button type="submit" name="operation" value="val-1">Operation #1</button>
<button type="submit" name="operation" value="val-2">Operation #2</button>
</form>
If you hit ENTER on this form, the following parameters will be sent:
foo=bar&operation=val-1
The updated answer is to use the button with formaction and formtarget
In this example, the first button launches a different url /preview in a new tab. The other three use the action specified in the form tag.
<button type='submit' class='large' id='btnpreview' name='btnsubmit' value='Preview' formaction='/preview' formtarget='blank' >Preview</button>
<button type='submit' class='large' id='btnsave' name='btnsubmit' value='Save' >Save</button>
<button type='submit' class='large' id='btnreset' name='btnsubmit' value='Reset' >Reset</button>
<button type='submit' class='large' id='btncancel' name='btnsubmit' value='Cancel' >Cancel</button>
Full documentation is here
In HTML5, you can use formaction & formmethod attributes in the input field
<form action="/addimage" method="POST">
<button>Add image</button>
<button formaction="/home" formmethod="get">Cancel</button>
<button formaction="/logout" formmethod="post">Logout</button>
</form>
You can also use a href attribute and send a get with the value appended for each button. But the form wouldn't be required then
href="/SubmitForm?action=delete"
href="/SubmitForm?action=save"
You can present the buttons like this:
<input type="submit" name="typeBtn" value="BUY">
<input type="submit" name="typeBtn" value="SELL">
And then in the code you can get the value using:
if request.method == 'POST':
#valUnits = request.POST.get('unitsInput','')
#valPrice = request.POST.get('priceInput','')
valType = request.POST.get('typeBtn','')
(valUnits and valPrice are some other values I extract from the form that I left in for illustration)
Since you didn't specify what server-side scripting method you're using, I'll give you an example that works for PHP
<?php
if(isset($_POST["loginForm"]))
{
print_r ($_POST); // FOR Showing POST DATA
}
elseif(isset($_POST["registrationForm"]))
{
print_r ($_POST);
}
elseif(isset($_POST["saveForm"]))
{
print_r ($_POST);
}
else{
}
?>

Forms
When click on Login -> loginForm
When click on Save -> saveForm
When click on Register -> registrationForm
Simple. You can change the action of form on different submit buttons click.
Try this in document.Ready:
$(".acceptOffer").click(function () {
$("form").attr("action", "/Managers/SubdomainTransactions");
});
$(".declineOffer").click(function () {
$("form").attr("action", "/Sales/SubdomainTransactions");
});
