I'm trying to get form data from my html page on a post request but when I use the getFormAttribute() function, it returns null. Here is the code:
Route postArticleRoute = router
.post("/articlePosted")
.handler(routingContext -> {
HttpServerResponse response = routingContext.response();
HttpServerRequest request = routingContext.request();
String title = request.getFormAttribute("title");
String auth = request.getFormAttribute("author");
String body = request.getFormAttribute("body");
System.out.println(title + auth + body);
});
This code returns: 'nullnullnull'
I've double checked that these are the name attributes in the html form. Just in case, here is the html:
<form action="/articlePosted" method="post">
<label>Title of Article</label><br>
<input type="text" name="title" id="postArticle-title"><br><br>
<label>Author</label><br>
<input type="text" name="author" id="postArticle-auth"><br><br>
<label>Image</label><br>
<input type="file" name="file" id="postArticle-img"><br><br>
<label>Body</label><br>
<textarea style="width: 100%; height: 500px;" name="body" id="postArticle-body"></textarea><br><br>
<input type="submit" value="Post">
</form>
Any help would be appreciated.

I've gone through dozens of articles, docs, and stack overflow questions (even the one with a similar intro)regarding the same issues but it still persists.
I've tried this with putting the functions in the .cshtml.cs page and on the .cshtml page, named and unnamed handler names, different framework for sending emails, and adding an empty action field in the form along with other fixes but the issue seems to be that the handler method itself is not firing while the form is submitting. Any and all help is appreciated and please let me know if more information is needed.
My HTML form:
<form method="POST" asp-page-handler="email">
<!-- Name input-->
<div class="form-floating mb-3">
<input class="form-control" name="clientName" type="text" placeholder="Enter your name..." required/>
<label for="name">Full name*</label>
</div>
<!-- Email address input-->
<div class="form-floating mb-3">
<input class="form-control" name="clientEmail" type="email" placeholder="name#example.com" required/>
<label for="email">Email address*</label>
</div>
<!-- Phone number input-->
<div class="form-floating mb-3">
<input class="form-control" name="clientPhone" type="tel" placeholder="(123) 456-7890"/>
<label for="phone">Phone number</label>
</div>
<!-- Message input-->
<div class="form-floating mb-3">
<textarea class="form-control" name="clientMessage" type="text" placeholder="Enter your message here..." style="height: 10rem" required></textarea>
<label for="message">Message*</label>
</div>
<!-- Submit Button-->
<div class="d-grid"><button class="btn btn-primary btn-xl" type="submit" value="submit">Submit</button></div>
</form>
My functions as they are currently:
public void OnPostEmail()
{
var clientEmail = Request.Form["clientEmail"];
var clientName = Request.Form["clientName"];
var clientPhone = Request.Form["clientPhone"];
var clientMessage = Request.Form["clientMessage"];
sendEmail(clientEmail, clientName, clientPhone, clientMessage);
}
public void sendEmail(string clientEmail, string clientName, string clientPhone, string clientMessage)
{
var errorMessage = "";
try
{
// Initialize WebMail helper
WebMail.SmtpServer = "smtp.google.com";
WebMail.SmtpPort = 587;
WebMail.UserName = "***#gmail.com";
WebMail.Password = "MYPASSWORD";
WebMail.From = "***#gmail.com";
WebMail.EnableSsl = true;
// Send email
WebMail.Send(to: clientEmail,
subject: $"Request from: + {clientName}",
body: $"{clientMessage}\nPhone: {clientPhone}\nEmail: {clientEmail}"
);
}
catch (Exception ex)
{
errorMessage = ex.Message;
}
}
On a Typo3 website a form is integrated. The action should be routed to a typoscript user function.
This is what I tried so far:
The fluid form code (excerpt):
<form action="{f:cObject(typoscriptObjectPath: 'lib.mynlreg')}" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
The typoscript lib:
lib.mynlreg = USER_INT
lib.mynlreg {
userFunc = Vendor\Extension\myClass->myFunction
}
And the class:
class myClass {
public function myFunction($content, $conf) {
$arguments = $this->request->getArguments();
$formEmail = $arguments['email'];
return '<div>' . $formEmail . '</div>';
}
}
I expect to get the content of the form field "email", but after submitting the page throws an error. The question is, how do I get the post vars into the user function? Thank you for any help!
$this->request is not available in a userFunc. As gautamsinh mori says, you should use \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('email');, however I'm not sure you understand what the f:cObject ViewHelper does.
With this code, your HTML before submitting the form will be:
<form action="<div></div>" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
Your HTML after submitting will be:
<form action="<div>filledInEmail</div>" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
I'd recommend making an extension for this, but if you really want/need to do it like this, I think what you're looking for is something like:
<f:cObject typoscriptObjectPath="lib.mynlreg" />
<form action="{uri.page(addQueryString: 1)}" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
This will create the form with action to the current page (including any query string). You then have to change the userFunc to return an empty string if the form hasn't been submitted. Something like:
class myClass {
public function myFunction($content, $conf) {
$formEmail = \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('email');
if (empty($formEmail)) {
return '';
}
return '<div>' . $formEmail . '</div>';
}
}
Form:
<form action="/test" method="GET">
<input name="cat3" value="1" type="checkbox">
<input name="cat3" value="5" type="checkbox">
<input name="cat3" value="8" type="checkbox">
<input name="cat3" value="18" type="checkbox">
<input type="submit" value="SUBMIT">
</form>
How to change URL form with GET method?
Before: test?cat3=1&cat3=5&cat3=8&cat3=18
After: test?cat3=1,5,8,18
I want to use jQuery.
Many thanks!
Here you go! This example, using jQuery, will grab your form elements as your question is asking and perform a GET request to the desired URL. You may notice the commas encoded as "%2C" - but those will be automatically decoded for you when you read the data on the server side.
$(document).ready(function(){
$('#myForm').submit(function() {
// Create our form object. You could optionally serialize our whole form here if there are additional parameters in the form you want
var params = {
"cat3":""
};
// Loop through the checked items named cat3 and add to our param string
$(this).children('input[name=cat3]:checked').each(function(i,obj){
if( i > 0 ) params.cat3 += ',';
params.cat3 += $(obj).val();
});
// "submit" our form by going to the properly formed GET url
var url = $(this).attr('action') + '?' + $.param( params );
// Sample alert you can remove
alert( "This form will now GET the URL: " + url );
// Perform the submission
window.location.href = url;
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="/test" method="GET" id="myForm">
<input name="cat3" value="1" type="checkbox">
<input name="cat3" value="5" type="checkbox">
<input name="cat3" value="8" type="checkbox">
<input name="cat3" value="18" type="checkbox">
<input type="submit" value="SUBMIT">
</form>
My friend found a solution:
$(document).ready(function() {
// Change Url Form: &cat3=0&cat3=1&cat3=2 -> &cat3=0,1,2
var changeUrlForm = function(catName){
$('form').on('submit', function(){
var myForm = $(this);
var checkbox = myForm.find("input[type=checkbox][name="+ catName +"]");
var catValue = '';
checkbox.each(function(index, element) {
var name = element.name;
var value = element.value;
if (element.checked) {
if (catValue === '') {
catValue += value;
} else {
catValue += '‚' + value;
}
element.disabled = true;
}
});
if (catValue !== '') {
myForm.append('<input type="hidden" name="' + catName + '" value="' + catValue + '" />');
}
});
};
// Press 'Enter' key
$('.search-form .inputbox-search').keypress(function(e) {
if (e.which == 13) {
changeUrlForm('cat3');
changeUrlForm('cat4');
alert(window.location.href);
}
});
// Click to submit button
$('.search-form .btn-submit').on('click', function() {
changeUrlForm('cat3');
changeUrlForm('cat4');
alert(window.location.href);
$(".search-form").submit();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="/test" method="GET" class="search-form">
<input name="cat3" value="1" type="checkbox">1
<input name="cat3" value="3" type="checkbox">3
<input name="cat3" value="5" type="checkbox">5
<input name="cat3" value="7" type="checkbox">7
<br />
<input name="cat4" value="2" type="checkbox">2
<input name="cat4" value="4" type="checkbox">4
<input name="cat4" value="6" type="checkbox">6

I replicated the Developer's example code with success. When i insert a div into the form it fails. How can i submit 'form div input' to a server side function?
* i believe divs and spans are allowed inside forms from here.
* uncommenting the divs causes the div 'output' not to update.
html:
<form id="myForm">
<!--><div>-->
<input name="myEmail" type="text" />
<input type="submit" value="Submit"
onclick="google.script.run.withSuccessHandler(updateEmail)
.processForm(this.parentNode)" />
<!--></div>-->
</form>
<div id="output">
</div>
<script>
function updateEmail(response) {
var div = document.getElementById("output");
div.innerHTML = "<p>" + response + "</p>";
}
</script>
code.gs
function doGet() {
var html = HtmlService.createTemplateFromFile('index').evaluate()
.setTitle('Web App').setSandboxMode(HtmlService
.SandboxMode.NATIVE);
return html;
}
function processForm(formObject) {
var response = "";
response = formObject.myEmail;
return response;
};
Edit:
changed:
<input type="button" value="Submit"
to:
<input type="submit" value="Submit"
I changed the HTML file to this:
<form id="myForm">
<div>
<input name="myEmail" type="text" />
<input type="button" value="Submit"
onclick="processFormJs(this.parentNode)" />
</div>
</form>
<div id="output"></div>
<script>
window.processFormJs = function(argDivParent) {
console.log('argDivParent: ' + argDivParent);
google.script.run.withSuccessHandler(updateEmail)
.processForm(argDivParent)
};
function updateEmail(response) {
var div = document.getElementById("output");
div.innerHTML = "<p>" + response + "</p>";
}
</script>
And added a console.log('argDivParent: ' + argDivParent); statement. Then in developer tools, show the console. I get this error:
argDivParent: [domado object HTMLDivElement DIV]
Failed due to illegal value in property: 0
this.ParentNode is referring to the DIV and not the FORM. If I take out the DIV, the object returned is:
argDivParent: [domado object HTMLFormElement FORM]
Not:
argDivParent: [domado object HTMLDivElement DIV]
A DIV probably doesn't automatically put INPUT values into it's parent object.
This code does work with a DIV:
<form id="myForm" onsubmit="processFormJs(this)">
<div>
<input name="myEmail" type="text" />
<input type="button" value="Submit"/>
</div>
</form>
<div id="output"></div>
<script>
window.processFormJs = function(argDivParent) {
console.log('argDivParent: ' + argDivParent);
google.script.run.withSuccessHandler(updateEmail)
.processForm(argDivParent)
};
function updateEmail(response) {
var div = document.getElementById("output");
div.innerHTML = "<p>" + response + "</p>";
}
</script>
For debugging, you can use Logger.log("your text here"); then view the Logs.
function processForm(formObject) {
Logger.log('processForm ran: ' + formObject);
var response = "";
response = formObject.myEmail;
Logger.log('response: ' + response);
return response;
};
I have a problem with Google Geocoder API.
I have a form where the user type a full address. When the form is submited, I want to extract the city from this address and put this city in a hidden field.
So here is what I've done...
HTML :
<form id="new_post" name="new_post" method="post" action="" onSubmit="codeAddress()">
<p>
<label for="adresse_de_depart">Adresse de départ</label><br />
<input type="text" id="adresse_de_depart" value="" tabindex="1" size="20" name="adresse_de_depart"/>
</p>
<input type="hidden" id="ville_depart" name="ville_depart" value=""/>
<p align="right">
<input type="submit" value="Publish" tabindex="6" id="submit" name="submit" />
</p>
</form>
JS :
<script>
var geocoder;
$(document).ready(function(){
geocoder = new google.maps.Geocoder();
});
function codeAddress() {
var adresse = document.getElementById("adresse_de_depart").value;
console.log(geocoder);
alert(adresse_de_depart);
geocoder.geocode( { 'address': adresse}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
alert("OK");
document.getElementById("ville_depart").value=results;
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}</script>
The first "alert" works but after the page is reloaded (and the form is submited). But I have no alert related to the geocode method...
Have you got an idea ?
Thanks !
