$('#id').change(function(){
var a = $('#id_one').val();
var token = '<?php echo csrf_token(); ?>';
$.ajax({
url: "url",
type: 'POST',
data: {'id':a,'_token':token},
success: function(data)
{
// some code
}
});
})
This is my code.
Getting token mismatch error..!!
I have tried both of the following..
<input type="hidden" name="_token" value="{{ csrf_token() }}" />
<script type="text/javascript">
var _globalObj = {{ json_encode(array('_token'=> csrf_token())) }}
Can any one help ??
You can utilize your token from the blade template, just declare your session token in the blade file of your view under the script tag like this:
<script> var token = '{{ Session::token() }}'; </script>
and call the token in ajax, in your code it will be something like this:
$('#id').change(function(){
var a = $('#id_one').val();
$.ajax({
url: "url",
type: 'POST',
data: {'id':a,'_token':token},
success: function(data)
{
// some code
}
});
})
Possibly because the token field name should be _token and not token
Also If this javascript code in a separate javascript file then php function will not work.
Also if the data you are trying to send is of a form then you can do this
$('#id').change(function(){
var data = $("#form").serialize() ;
$.ajax({
url: "url",
type: 'POST',
data: data,
success: function(data)
{
// some code
}
});
})
where your form looks like
<form id="form">
<input type='hidden' value='{{ csrf_token() }}' name='_token'>
<input type="text" name='id'>
</form>
$.ajax({
url: someurl,
type: 'POST',
data : formData,
headers: {
"x-csrf-token": $("#token").data('id')
}
});
}
and in your html
<div id="token" data-id="{!! csrf_token() !!}"></div>

Form submit is not happened in this scenario..
$.ajax({
type: "POST",
async: false,
url: base_url+"register/registration_val",
data: "register_first_name="+first_name,
success: function(data){
$('#inferiz').html(data);
},
error: function(){
alert('error');
}
In your view you can add this:
<script type="text/javascript">
var base_url = "<?php print base_url(); ?>";
</script>
Plus try to alert and see the value of final url in ajax i.e alert(url);
Try adding a id to the firstname input
<script type="text/javascript">
$(document).on('submit','#form-reg',function(){ // #form-reg is id on form open tag
$.ajax({
url: "<?php echo base_url('register/registration_val');?>",
type: 'POST',
data: {
firstname: $('#firstname').val(),
},
dataType: 'html', // I perfer to use json
success: function(data){
$('#inferiz').html(data);
},
error: function(){
alert('error');
}
}
});
});
</script>
I would use dataType: json much easier that way to get data from controller
You used data: "register_first_name="+first_name, it's not correct. Correction is data: {register_first_name:first_name},
base_url like this var base_url = <?php echo base_url(); ?>
So, Bellow final code :
<script type="text/javascript">
jQuery(document).ready(function ($) {
var base_url = <?php echo base_url(); ?>
$.ajax({
url: base_url+"register/registration_val", // Url to which the request is send
type: "POST", // Type of request to be send, called as method
data: {register_first_name:first_name}, // Data sent to server, a set of key/value pairs representing form fields and values
contentType: false, // The content type used when sending data to the server. Default is: "application/x-www-form-urlencoded"
}).done(function (data) {
$('#inferiz').html(data);
}).fail(function (data) {
console.log('failed');
});
}(jQuery));
</script>
Please verify your view part that whether you provided id same as in ajax function.
view part:
<form id="form-reg">
<input name="firstname" id="firstname" type="text" required placeholder="Enter firstname " >
<span id="name_validation" class="text-danger"></span>
<button name="submit" id="submit_button" onClick="myFunction();" >submit</button>
</form>
Then correct the base url path which has to be given inside php tag.
function myFunction() {
$.ajax({
url: "<?php echo base_url();?>register/registration_val",
type: "POST",
data:'firstname='+$("#firstname").val(),
success: function(msg)
{
alert('done..!');
}
});
}
I am trying to post File using JQuery. Below is my code.
<script language="javascript">
$(document).ready(function() {
$('#frmUpdateProfile').on("submit", function(event) {
event.stopPropagation(); // Stop stuff happening
event.preventDefault(); // Totally stop stuff happening
var data = {
"FileName" : event.target.FileName.files,
"_token" : "{!! csrf_token() !!}"
};
$.ajax({
url: '{{URL::route("UpdateProfile")}}',
method: "POST",
async: true,
data: JSON.stringify(data),
processData: false,
contentType: "application/json; charset=utf-8",
success: function (msg) {
SuccessCallback(msg);
},
error: function (jqXHR) {
ErrorCallback(jqXHR);
}
});
});
});
</script>
I tried processData: false,. While debugging in Js, you can check that image is coming in the data. Below is the screenshot.
But when I print the request data in Laravel, it show blank array.
Html form is here
<form method="POST"
action="http://localhost:1234/AS6-Code/public/UpdateProfile"
accept-charset="UTF-8"
enctype="multipart/form-data"
id="frmUpdateProfile">
<input name="_token" type="hidden" value="26KWkWdNqe5iOFE8VRBf1dRnL5xKxwN25jg3tAFW">
<input type="hidden" name="_token" value="26KWkWdNqe5iOFE8VRBf1dRnL5xKxwN25jg3tAFW">
<input multiple="1" name="FileName" type="file">
<input class="btn btn-info" type="submit" value="Update">
</form>
Am I doing something wrong?
Try sending your request with FormData instead:
var data = new FormData($('#frmUpdateProfile')[0]);
Also set contentType to false:
contentType: false
Also Update
event.target.FileName.files
to
event.target.FileName.files[0]
event.target.FileName.files is a FileList object. I believe you need event.target.FileName.files[0] instead.
i have a form with method=post.In that form i have an image upload field which is ajax.when the ajax call process,verify csrf token mismatch error occure.help me.this is my code..,
<script>
$(document).ready(function(){
$(document).on("click", "#upload", function() {
var file_data = $("#groupe_img").prop("files")[0]; // Getting the properties of file from file field
var form_data = new FormData(); // Creating object of FormData class
form_data.append("file", file_data) // Appending parameter named file with properties of file_field to form_data
form_data.append("csrftoken",document.mainform.csrftoken.value;) // Adding extra parameters to form_data
$.ajax({
url: "/upload_avatar",
dataType: 'script',
cache: false,
contentType: false,
processData: false,
data: form_data, // Setting the data attribute of ajax with file_data
type: 'post'
})
})
});
</script>
this is my html portion
<input type="file" name="groupe_img" id="groupe_img">
<button id="upload" value="Upload">upload image</button>
tysm
First add csrf token to a meta tag like this (in main layout for example: resources/views/default.blade.php in head section):
<meta name="_token" content="{{ csrf_token() }}"/>
Then use $.ajaxSetup before ajax call:
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
}
});
$.ajax({
url: "/upload_avatar",
dataType: 'script',
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post'
})
these are code snippet for sending json data with ajax.
you can show same code in the last postings.
I'm just follow the code.
But I got 403 error
jsonpost.html
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#mySelect").change(function(){
selected = $("#mySelect option:selected").text()
$.ajax({
type: 'POST',
dataType: 'json',
contentType: 'application/json; charset=utf-8',
url: '/test/jsontest/',
data: {
'fruit': selected,
'csrfmiddlewaretoken': '{{ csrf_token }}'
},
success: function(result) {
document.write(result)
}
});
});
});
</script>
</head>

<form>
{% csrf_token %}
{{ data }}

Select your favorite fruit:
<select id="mySelect">
<option value="apple" selected >Select fruit</option>
<option value="apple">Apple</option>
<option value="orange">Orange</option>
<option value="pineapple">Pineapple</option>
<option value="banana">Banana</option>
</select>
</form>
</body>
</html>
urls.py
urlpatterns = patterns('',
url(r'^jsontest/$', views.JsonRead.as_view(), name='userTest'),
)
views.py
class JsonRead(View):
def get(self,request):
return render(request, 'MW_Etc/jsonpost.html')
def post(self,request):
print(request.body)
data = request.body
return HttpResponse(json.dumps(data))
After change the fruit value, I got the error.
How can I resolve this?
Any others good ways is good as well.
If you are using post method you have to send csrf token in the form,same has to be done in the case of ajax
$(document).ready(function(){
$("#mySelect").change(function(){
selected = $("#mySelect option:selected").text()
$.ajax({
type: 'POST',
dataType: 'json',
contentType: 'application/json; charset=utf-8',
url: '/test/jsontest/',
data: {
'fruit': selected,
csrfmiddlewaretoken: '{{ csrf_token }}'
},
success: function(result) {
document.write(result)
}
});
});
});
try like this,this worked for me.
Problem: I'm trying to send ajax reguest, and then submit the form.
Aproaches:
1. I solved the problem by putting
success: function() {
document.myform.submit();
}
But i think it's not the most elegant solution. Can you explain me why it works only if i put document.myform.submit(); in success? Is there any other way to solve this problem?
<div class="buttons">
<div class="right">
<form name="myform" onsubmit="javascript: startAjax(); return false;" action="https://example.com/payment.php" method="get">
<input type="hidden" name="merchantId" value="<?php echo $merchantIdKZM; ?>">
<input type="submit" value="<?php echo $button_confirm; ?>" id="button-confirm2" class="button" name="PayKZM" />
</form>
</div>
</div>
<script type="text/javascript">
function startAjax() {
console.log("dafaaaa");
$.ajax({
type: 'get',
url: 'index.php?route=payment/bank_transfer/confirm',
async: 'false',
success: function() {
// location = '<?php echo $continue; ?>';
}
});
} // Calls ajaxComplete() when finished
function ajaxComplete()
{
console.log("dafa");
document.myform.submit();
}
</script>
success's function is called upon the get request receiving a valid response as #harsh pointed out. Thus it will occur after the get request. I believe something similar to the following would do as you request though I haven't tested it:
<script type="text/javascript">
$(function () {
$("#form").on('submit', function () {
var $form = $(this);
$.ajax({
type: 'GET',
url: 'index.php?route=payment/bank_transfer/confirm',
data: $form.serialize(),
async: 'false',
success: function () {
$.ajax({
type: 'GET',
url: 'https://example.com/payment.php',
data: $form.serialize(),
});
}
});
});
});
</script>
