Hi Im attempting a simple ajax request but I keep getting a null value for json.
Here is my javascript...
<script>
$(document).ready( function() {
$('#donate-box-submit').on('click', function() {
var donate_code = $('#charity-campaign-code').val();
var donate_amount = $('#charity-campaign-amount').val();
$.ajax({
url: 'index.php?route=donate/donatenow',
type: 'post',
data: {
donate_code: donate_code,
donate_amount: donate_amount
},
dataType: 'json',
beforeSend: function() {
},
complete: function() {
},
success: function(json) {
console.log(json);
alert(json['test']);
},
error: function() {
}
});
});
});
</script>
and my php...
public function donatenow() {
$json = array(
'test' => 'Output this text'
);
$this->response->setOutput(json_encode($json));
}
I have also tried echo json_encode($json); just to rule out any issues with that OpenCart function, but the same issue is still there.
The problem is the route you are using to call the method. Not sure on exactly what class you are using as the controller, but there should be three parts to the route: route=aaa/bbb/donatenow where as you've got aaa/donatenow

I'm trying to implement the EasyAutoComplete plugin on a field based on the value filled in another field, using ajax requests.
I have a customerid field and when it's value changes, I want the productname field to show all products related to that customerid using the EasyAutoComplete plugin.
Here is what I have so far:
$('#customerid').on('change',function() {
var products2 = {
url: function(phrase) {
return "database/FetchCustomerProducts.php";
},
ajaxSettings: {
dataType: "json",
method: "POST",
data: {
dataType: "json"
}
},
preparePostData: function(data) {
data.phrase = $("#customerid").val();
return data;
},
getValue: "name",
list: {
onSelectItemEvent: function() {
var value = $("#productname").getSelectedItemData().id;
$("#productid").val(value).trigger("change");
},
match: {
enabled: true
}
}
};
$("#productname").easyAutocomplete(products2);
});
Contents of FetchCustomerProducts.php:
if(!empty($_POST["customerid"])){
$products = $app['database']->Select('products', 'customerid', $_POST['customerid']);
echo json_encode(['data' => $products]);
}
However it's not working. The code is based on the 'Ajax POST' example found on this page.
you can using element select category add is class "check_catogory"
after using event click element select get value is option, continue send id to ajax and in file php, you can get $_POST['id'] or $_GET['id'], select find database,after echo json_encode
$("#customerid").change(function(){
var id = $(this).val();
if(id!=""){
$.ajax({
url:"database/FetchCustomerProducts.php",
type:"POST",
data:{id:id},
dataType: "json",
cache:false,
success:function(result){
var options = {
data:result,
getValue: "name",
list: {
onSelectItemEvent: function() {
var value = $("#productname").getSelectedItemData().id;
$("#productid").val(value).trigger("change");
},
match: {
enabled: true
}
}
};
$("#productname").easyAutocomplete(options);
}
})
}
});
My problem is lack of action after pressing the button. Under the button hook AJAX function.
Please a hint where I have a bug // errors.
My code:
Controller:
[HttpPost]
public ActionResult InsertCodesToDB(string name)
{
cl.InsertCodesToDB(name);
fl.MoveCodeFileToAccept(name);
string response = "Test";
return Content(response, "application/json");
}
View / Button:
<input type="button" class="btn btn-success sendCodesToDB" value="Umieść kody w bazie" data-value="#item.Name"/>
View / Script:
<script>
$('.sendCodesToDB').on('click', function () {
var name = $(this).data("value");
$.ajax({
url: '/ActualCodes/InsertCodesToDB',
type: 'POST',
dataType: 'json',
cache: false,
data: JSON.stringify({ 'name': 'name' }),
success: function (response) {
#(ViewBag.MessageOK) = response;
},
error: function () {
onBegin;
}
});
});
function onBegin() {
$('#files').hide();
$('#insertFiles').hide();
$('#loading').show();
$('#lblSelectedProductName').text('Trwa umieszczanie kodów w bazie danych. Proszę czekać ...');
$('#ttt').show();
}
</script>
Thank you in advance for your help.
You seem to not be adding the on ready function for jQuery. Try adding it before your click action and closing it before your onBegin() function, like so:
<script>
// open here
$( document ).ready(function() {
$('.sendCodesToDB').on('click', function () {
var name = $(this).data("value");
$.ajax({
url: '/ActualCodes/InsertCodesToDB',
type: 'POST',
dataType: 'json',
cache: false,
data: JSON.stringify({ 'name': 'name' }),
success: function (response) {
#(ViewBag.MessageOK) = response;
},
error: function () {
// function call missing "()"
onBegin();
}
});
});
// and close here
});
function onBegin() {
$('#files').hide();
$('#insertFiles').hide();
$('#loading').show();
$('#lblSelectedProductName').text('Trwa umieszczanie kodów w bazie danych. Proszę czekać ...');
$('#ttt').show();
}
</script>
The code in Ajax must be JavaScript. You cannot use C# code there (except to print some values). What is #(ViewBag.MessageOK) doing here:
success: function (response) {
#(ViewBag.MessageOK) = response;
},
If you want to display the response in a message box, try something like:
success: function (response) {
$("#your_message_id").html(response);
},
Notes: aside from that, you have several errors in your code as others pointed out in the comments.
1- Remove the quotes from the data like this:
data: JSON.stringify({ name: name }),
2- Change the error to this:
error: function () {
onBegin(); // You need "()" here
}
Or better this:
error: onBegin // You don't need "()" here
I guess you are sending data inside the AJAX call in the wrong way.
Try it like this
data: JSON.stringify({ name: name })
Hope this will help you.
This is the code:
Controller:
public function isreadAction(Request $request) {
var_dump($request->get('sentValue'));
$em = $this->getDoctrine()->getEntityManager();
$pm = $this->getDoctrine()
->getRepository('LoginLoginBundle:Privatemessage')
->findBypmid($request->get('sentValue'));
$pm->setIsRead(true);
$em->flush();
return new Response();
}
js:
$(document).ready(function () {
$(".pmcontents").hide();
$(".pmbox").click(function () {
$(this).css("font-weight", "normal");
$(this).next().toggle();
var myValue = $('this').attr('id');
var DATA = 'sentValue=' + myValue;
$.ajax({
type: "POST",
url: Routing.generate('isread'),
data: DATA,
cache: false,
success: function (data) {
alert("database has been updated");
}
});
});
});
Routing:
isread:
path: /game/isread
defaults: { _controller: LoginLoginBundle:Default:isread }
requirements:
options:
expose: true
If i click on the error it says that the variable is undefined:
Parametersapplication/x-www-form-urlencodedNiet sorteren
sentValue undefined
Bron
sentValue=undefined
What is the problem? I have tried some things and it seems that the problem lies within the ajax part of the javascript, but i'm not sure.
Replace
var myValue = $('this').attr('id'); //<- notice quote around this
with
var myValue = $(this).attr('id');
i'm having a html.dropdownlist where ochange event is speified. i need to call a controller action method using ajax or javascript function and returns view based on the filter value
I try someting like following which is not working,why?
<script type="text/javascript">
$(function() {
$('#Projcbo1').change(function () {
// fetch the newly selected value
var selectedValue = $(Projcbo1).val();
// send it as an AJAX request to some controller action
$.post('#Url.Action("ProjCBOItemSelected")', { value: selectedValue }, function (result) { $("#resultContainer").html(result); });
});
});
</script>
You can use the following to achieve that.
<script>
$(function() {
$('#ddl').change(function () {
$.ajax({
url: '#Url.Action("actionname", "controllername")',
type: 'GET',
dataType: 'html',
data: {Id: $(this).val() },
success: function (result) {
$('#div_to_load_the_content').html(result);
},
error: function (error) {
},
});
});
});
</script>
Let me know if it helps.
I am doing some Add, Edit, and Delete for my project in school. The codes in the add module went well, in fact I've added few records. Then, here comes the Edit module, at first it was quite good, similar codes was used from the add module. But as I try and try, the post in the edit module was empty.
here's my edit codes:
$(".careersEdit").click(function () {
var careersTableSelect = encodeURIComponent($("input:radio[name=careersTableSelect]:checked").val());
if (careersTableSelect > 0) {
$(".careersEditForm_load").show();
$(".careersEditForm_error").hide();
$(".careersEditForm").hide();
var dataStringCareersEdit = 'careersTableSelect=' + careersTableSelect;
$.ajax({
type: "POST",
url: "admin/careers/process/careersEditGet.php",
data: dataStringCareersEdit,
beforeSend: function(){
alert(dataStringCareersEdit);
},
success: function () {
setTimeout("", 5000);
fetchResult();
},
error: function () {
alert("Post Error");
}
});
function fetchResult() {
$.ajax({
url: "admin/careers/process/careersEditGet.php",
type: "POST",
dataType: "json",
success: function (result) {
if (result) {
$("input#careersEditPosition").val(result['position']);
$("input#careersEditCompany").val(result['company']);
$("input#careersEditLocation").val(result['location']);
$(".careersEditForm_load").hide();
$(".careersEditForm").show();
}
},
error: function () {
alert("Fetch Error");
}
});
}
} else {
$(".careersEditForm").hide();
$(".careersEditForm_load").hide();
$(".careersEditForm_error").show();
}
});
Here's the careersEditGet.php:
<?php
include('connect.php');
error_reporting(0);
$careersTableSelect = $_POST['careersTableSelect'];
//$careersTableSelect = $careersTableSelect + 1;
//echo $careersTableSelect;
$query = "SELECT * FROM atsdatabase.admincareers WHERE refNum ='" . $careersTableSelect . "' LIMIT 0 , 30";
$runQuery = mysql_query($query);
if (!$runQuery) {
die('Could not enter data: ' . mysql_error());
}
$result = mysql_fetch_row($runQuery);
$array = array(
'position' => "" . $result[1] . "",
'company' => "" . $result[2] . "",
'location' => "" . $result[3] . "",
);
echo json_encode($array);
mysql_close($connection);
?>
Yes, the code is ugly/wrong/crap, I'm quite new to jquery stuffs, about 3-4 days. To those that will help, please do correct me. I wanna learn this jquery ajax stuff. Gracias
Maybe try passing data in more common way:
change
data: dataStringCareersEdit,
to
data: { "careersTableSelect" : careersTableSelect },
Call your ajax function once like,
$.ajax({
url: "admin/careers/process/careersEditGet.php",
type: "POST",
dataType: "json",
data: {careersTableSelect: careersTableSelect},
success: function (result) {
if (result) {
$("input#careersEditPosition").val(result.position);// json not array
$("input#careersEditCompany").val(result.company);// json not array
$("input#careersEditLocation").val(result.location);// json not array
$(".careersEditForm_load").hide();
$(".careersEditForm").show();
}
},
error: function () {
alert("Fetch Error");
}
});
Thanks guys for all the effort to answer this question, I've consulted to a friend who's a web developer, taught me how to properly use ajax in jquery. ;)
You are doing something fundamentally wrong when u are posting Data from jQuery.Ajax..
The data should be an object and the key should be the name of the server side POST variable which will be used later in the PHP ...
Example :
data : {"server_side_vriable" : "Your_data_to_Post" }
......
var dataStringCareersEdit = 'careersTableSelect=' + careersTableSelect + "&careersTableSelect=" + careersTableSelect;
$.ajax({
type: "POST",
url: "admin/careers/process/careersEditGet.php",
data: {"careersTableSelect" : dataStringCareersEdit},
beforeSend: alert(dataStringCareersEdit),
success: function () {
alert("Fetching Result");
setTimeout("", 3000);
$.ajax({
url: "admin/careers/process/careersEditGet.php",
type: "GET",
dataType: "json",
success: function (result) {
if (result) {
$("input#careersEditPosition").val(result['position']);
$("input#careersEditCompany").val(result['company']);
$("input#careersEditLocation").val(result['location']);
$(".careersEditForm_load").hide();
$(".careersEditForm").show();
}
},
error: function () {
alert("Fetch Error");
}
});
},
error: function () {
alert("Post Error");
}
});
