I have a form and I want to send values to my controller
I wrote this codes but it returns me MethodNotAllowedHttpException error,
I have a html form
I send it with POST method
My route is post too
My form:
<form method="post" id="form">
{{csrf_field()}}
<input type="text" name="fname" id="fname">
<input type="text" name="lname" id="lname">
<input type="submit" name="submit-btn" id="submit-btn">
<h4 id="head"></h4>
</form>
JS:
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$(document).ready(function(){
$('#form').submit(function () {
$.ajax({
type : 'POST',
url : '{{route('routeName')}}',
data : {
fname: $("input#fname").val(),
lname: $("input#lname").val(),
},
error: function (xhr, ajaxOptions, thrownError) {
//alert(xhr.status);
//alert(thrownError);
},
success: function(result){
$('#head').text(result.head);
}
});
});
});
</script>
My Route :
Route::post('routeName' , [
'uses' => 'SomeController#Generate',
'as' => 'routeName']);
Controller :
public function Generate(){
$resp = array();
$fname= Input::get('fname');
$lname= Input::get('lname');
$resp["status"] = "ok";
return (Response::json($resp));}
And the error is :
error
Try this:
</script>
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$(document).ready(function(){
$('#form').submit(function (e) {
e.preventDefault(); //**** to prevent normal form submission and page reload
$.ajax({
type : 'POST',
url : '{{route('routeName')}}',
data : {
fname: $("input#fname").val(),
lname: $("input#lname").val(),
},
success: function(result){
console.log(result);
$('#head').text(result.status);
},
error: function (xhr, ajaxOptions, thrownError) {
//alert(xhr.status);
//alert(thrownError);
}
});
});
});
</script>
Add Request in controller method Generate
public function Generate(Request $request){
$resp = array();
$fname = $request->fname;
$lname = $request->lname;
$resp["status"] = "ok";
return Response::json($resp);
}
Hope it helps.
Try changing the following:
url : '{{url('routeName')}}',
and
return Response::json($resp);
don't forget to prevent the default submit event
$('#form').submit(function (e) {
e.preventDefault();
..........
and change:
$('#head').text(result.status);

I am creating a form using reCAPTCHA v2 and want the form to be able to be submitted again without reloading the page. When I submit the form for the first time, it works as expected. However, when I submit the form again without reloading the page, my CaptchaValidate function will be called twice, first returning false, then returning true. Why is this happening? Any help would be brilliant, thanks.
HTML
<form id="form" method="POST">
<label for="name">Name</label>
<input class="form-control" id="name" name="name">
<label for="age">Age</label>
<input class="form-control" id="age" name="age">
<button class="g-recaptcha" data-sitekey="myKey" data-callback="onSubmit" type="submit">Submit</button>
</form>
Javascript
function onSubmit(response) {
$('#form').submit(function (e) {
e.preventDefault();
const formData = $(this).serializeArray();
$.ajax({
url: '/Home/CaptchaValidate',
type: 'POST',
dataType: 'text',
data: { dataToken: response },
success: function (resultData) {
if (resultData == 'true') {
//do something
}
else {
$('.error-message').html('could not submit form');
}
},
error: function (err) {
console.log(err);
}
})
}).submit();
grecaptcha.reset();
}
Controller
[HttpPost]
public async Task<string> GetCaptchaData(string dataToken)
{
HttpClient httpClient = new HttpClient();
string secretKey = "mySecretKey";
var res = httpClient.GetAsync("https://www.google.com/recaptcha/api/siteverify?secret=" + secretKey + "&response=" + dataToken).Result;
if (res.StatusCode != HttpStatusCode.OK)
return "false";
string JSONres = res.Content.ReadAsStringAsync().Result;
dynamic JSONdata = JObject.Parse(JSONres);
if (JSONdata.success != "true")
return "false";
return "true";
}
try use e.stopImmediatePropagation();
it stops the rest of the event handlers from being executed.
function onSubmit(response) {
$('#form').submit(function (e) {
e.preventDefault();
e.stopImmediatePropagation(); // new line
const formData = $(this).serializeArray();
$.ajax({
url: '/Home/CaptchaValidate',
type: 'POST',
dataType: 'text',
data: { dataToken: response },
success: function (resultData) {
if (resultData == 'true') {
//do something
}
else {
$('.error-message').html('could not submit form');
}
},
error: function (err) {
console.log(err);
}
})
}).submit();
grecaptcha.reset();
}
I have a form on click of submit the input box is highlighted with the red color border if it is empty. Now i have jquery ajax form submission on success of the form i will display a message "data submitted" and i will reset the form so all the input fields will be highlighted in red color. Now i want to empty the fields after the success of form submission and it should not be highlighted in red color.

I'm not clear with your question, Do you want to reset form or remove the error class. But anyways I'll try solving out both :
SCRIPT
<script type="text/javascript">
(function() {
'use strict';
window.addEventListener('load', function() {
var form = document.getElementById('index-validation');
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add('was-validated');
}, false);
}, false);
})();
$(".index-form").submit(function(e) {
e.preventDefault();
return false;
} else {
var ins_date=new Date($.now()).toLocaleString();
var parms = {
name : $("#name").val(),
email : $("#email").val(),
inserted_date:ins_date
};
var url2="http://localhost:3000/api";
$.ajax({
method: 'POST',
url: url2 + "/homes",
async: false,
dataType : "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(parms),
success: function(data){
console.log('Submission was successful.');
//if you are removing specific property from class
$(".alert-success").css('display', 'none');
$(".alert-success").fadeTo(2000, 500).slideUp(500, function(){
$(".alert-success").slideUp(500);
});
$("form")[0].reset();
console.log(data);
}, error: function (data) {
console.log('An error occurred.');
console.log(data);
},
})
}
});
</script>
Jquery doesn't support any method such as reset() of javascript, So you can trigger javascript's reset() method.
Feel free to ask doubts if stuck. Happy coding....!!!!!
$(this.('.index-form').find("input[type=text]").val("");
You can just empty the form value by giving the .val() as empty, you have to give this on after your ajax response.
and also instead of using fade in and fade out just try to use hide and show function both may work like same.
I have a form which should submit data after pressing the submit button. After tagging a few input fields as required the form always shows me when there is no input in the required field after pressing the submit button - so far, so good.
What I would like to realize is that there is a redirection to another page if the submission was successful. If there are some empty required fields the form should show me, without redirecting me to another page.
By now I have the following code:
Submit button:
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" name="submityes" id="submityes" class="btn btn-danger">Submit</button>
</div>
</div>
Also I have the following js function to submit the form and to redirect me to another page:
$('document').ready(function () {
"use strict";
$(function () {
$('#submityes').click(function () {
$.ajax({
type: "POST",
/* url: "process.php", //process to mail
data: $('form.contact').serialize(), */
success: function (msg) {
window.location.replace("/submit_resolved.php");
},
error: function () {
alert("error");
}
});
});
});
});
The problem I have right now is that I will always be redirected to the "submit_resolved.php" page, whether all required fields are complete or not.
How can I solve this problem? I only want to be redirected when all required fields are not empty.
You should bind to the submit event, not click event:
UPDATED TO MATCH THE COMMENTS
$(function () {
var submityesClicked;
//catch the click to buttons
$('#submityes').click(function () {
submityesClicked = true;
});
$('#submitno').click(function () {
submityesClicked = false;
});
$('#webform').submit(function (e) {
e.preventDefault();//prevent the default action
$.ajax({
type: "POST",
/*url: "process.php", //process to mail
data: $('form.contact').serialize(),*/
success: function (msg) {
window.location.replace(submityesClicked ? "/submit_resolved_yes.php" : "/submit_resolved_no.php");
},
error: function () {
alert("error");
}
});
});
});
The submit event is triggered only if the form is valid.
Note that the submit event is triggered by the form but the click event is triggered by the input element.
Do redirection on complete. Not on success
$('document').ready(function () {
"use strict";
$(function () {
$('#submityes').click(function () {
$.ajax({
type: "POST",
/* url: "process.php", //process to mail
data: $('form.contact').serialize(), */
success: function (msg) {
//window.location.replace("/submit_resolved.php");
},
complete: function () {
window.location.replace("/submit_resolved.php");
},
error: function () {
alert("error");
}
});
});
});
});
I assume you are validating form in process.php so, you have to return error if validation fail from process.php like this.
header('HTTP/1.1 500 Internal Server Booboo');
header('Content-Type: application/json; charset=UTF-8');
die(json_encode(array('message' => 'ERROR', 'code' => 1337)));
check this link: Return errors from PHP run via. AJAX?
Hope this may be helpful to you.
The simplest thing you can do is to add "required" attribute to you input elements.Example:
<form action="/action_page.php">
Username: <input type="text" name="usrname" required>
<input type="submit">
</form>
It's a HTML5 attribute, so no JavaScript required. And it is supported by all major browsers. Check this link:
http://caniuse.com/#search=required
Anyway, you shouldn't rely just on front-end verification. Check those inputs on back-end, too.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<form action="">
Username: <input type="text" id="usrname" required>
<button type="button" name="submityes"
id="submityes" class="btn btn-danger">Submit</button>
</form>
</div>
function isValid(){
var usrname = $("#usrname").val();
if(usrname == ""){
return false;
}
return true;
}
$(function () {
$('#submityes').submit(function () {
if(isValid() == true){
$.ajax({
type: "POST",
/*url: "process.php", //process to mail
data: $('form.contact').serialize(),*/
success: function (msg) {
alert("success");
window.location.replace("/submit_resolved.php");
},
});
}else{
alert("error");
}
});
});
I have a request with ajax that still loads the php script instead of performing its function without refreshing. Am guessing there is an issue with my ajax Below is anything wrong with the ajax script
HTML
<form action='connect_exec.php' method='post' id='connect_form' enctype='multipart/form-data'>
<input type='text' name='conn_id' id='conn_id' value='$ad_id'>
<input type='submit' name='connect' class='conn_text' id='connect' value='connect +'>
</form>
Ajax request
$('#connect_form').submit(function(e) {
e.preventDefault();
var ad_id = $('#conn_id').val();
$.ajax({
type: "POST",
url: "connect_exec.php",
data: ad_id
}).done(function(response) {
console.log(response);
}).fail(function(data) {
console.log(data);
});
});
PHP SCRIPT
require_once("db.php");
$db = new MyDB();
session_start();
if (isset($_POST['connect'])) {
$my_id = $_SESSION['log_id'];
$ad_id = $_POST['conn_id'];
$rand_num = rand();
$hsql = <<<EOF
SELECT COUNT(hash) as count FROM connect WHERE(user_one = '$my_id'
AND user_two = '$ad_id') OR(user_one = '$ad_id'
AND user_two = '$my_id');
EOF;
$hret = $db->querySingle($hsql);
if ($hret == 1) {
$response = "Your are already connected to '$ad_id'";
} else {
$csql = <<<EOF
INSERT INTO connect(user_one, user_two, hash) VALUES('$my_id', '$ad_id', '$rand_num');
EOF;
$cret = $db - > exec($csql);
if (!$cret) {
echo "Error connecting to '$ad_id'";
} else {
echo "Successful";
}
}
}
The form executes but not without refreshing the page. Please what is the issue with the ajax?
I recommend you to send form data serialized, using serialize() method.
Also, use submit event for form: $('form').on('submit', function (e) {}
$('form').on('submit', function (e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "connect_exec.php",
data: $('form').serialize()
}).done(function(response) {
console.log(response);
}).fail(function(data) {
console.log(data);
});
});
$('#connect').click(function(e) {
e.preventDefault();
var ad_id = $('#conn_id').val();
console.log(ad_id);
$.ajax({
type: "POST",
url: "connect_exec.php",
data: ad_id
})
.done(function (response) {
console.log(response);
})
.fail(function (data) {
console.log(data);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action='connect_exec.php' method='post' id='connect_form' enctype='multipart/form-data'>
<input type='text' name='conn_id' id='conn_id' />
<input onclick="return;" type='submit' name='connect' class='conn_text' id='connect' value='connect +'>
</form>
I am trying to send a newsletter subscription request to Magento, but It returns null and nothing happens.
I've searched around and found very different URLs to post the request. And also grabbed the code from the file from base template.
In fact, maybe I am not sending the correct parameters or whatever.
This is the code in use:
<form method="post" id="newsletter-form">
<input type="hidden" class="url" value="<?php echo $this->getUrl('newsletter/subscriber/new') ?>">
<input id="newsletter" type="text" name="email" placeholder="RECEBA NOVIDADES" value="" class="input-text myFormInput" maxlength="128" autocomplete="off" style="width: 188px !important">
<button type="submit" id="ajax-newsletter-submit" title="CADASTRAR"
class="button myFormButton" style="margin-top:20px;margin-left: -107px !important;width: 103px">CADASTRAR</button>
</div>
</form>
Javascript:
var newsletterSubscriberFormDetail = new VarienForm('newsletter-form');
$j(function() {
$j("#ajax-newsletter-submit").click(function() {
var email =$j("#newsletter").val();
var url=$j(".url").val();
var dataString = 'email='+ email;
if(email=='') {
$j("#newsletter").focus();
} else {
var a = email;
var filter = /^[a-zA-Z0-9_.-]+#[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{1,4}$/;
if(filter.test(a)){
$j.ajax({
type: "POST",
url: url,
data: dataString,
success: function(){
alert('Assinatura realizada com sucesso!');
$j("#newsletter").val('');
}
});
} else {
$j("#newsletter").focus();
}
}
return false;
});
});
Try this code,
var val_form = new VarienForm('your form id');
jQuery("#your form id").submit(function(e)
{
if (val_form.validator && val_form.validator.validate())
{
var postData = jQuery(this).serializeArray();
var formURL = jQuery(this).attr("action");
jQuery.ajax(
{
url : formURL,
type: "POST",
data : postData,
success:function(data, textStatus, jqXHR)
{
alert('success');
},
error: function(jqXHR, textStatus, errorThrown)
{
alert('Failure');
}
});
this.reset(); //form field reset
e.preventDefault(); //STOP default action
e.unbind(); //unbind. to stop multiple form submit.
}
});
