Passing JSON object to PHP script

I am trying to pass a JSON object that looks similar to this:
{"service": "AAS1", "sizeTypes":[{"id":"20HU", "value":"1.0"},{"id":"40FB","2.5"}]}
Just a note: In the sizeTypes, there are a total of about 58 items in the array.
When the user clicks the submit button, I need to be able to send the object to a PHP script to run an UPDATE query. Here is the javascript that should be sending the JSON to the PHP script:
$('#addNewSubmit').click(function()
{
var payload = {
name: $('#addservice').val();
sizeTypes: []
};
$('input.size_types[type=text]').each(function(){
payload.sizeTypes.push({
id: $(this).attr('id'),
value: $(this).val()
});
});
$.ajax({
type: 'POST',
url: 'api/editService.php',
data: {service: payload},
dataType: 'json',
success: function(msh){
console.log('success');
},
error: function(msg){
console.log('fail');
}
});
});
Using the above click function, I am trying to send the object over to php script below, which is in api/editService.php:
<?php
if(isset($_POST['service']))
{
$json = json_decode($_POST['service'], true);
echo $json["service"]["name"] . "<br />";
foreach ($json["service"]["sizeTypes"] as $key => $value){
echo $value["value"] . "<br />";
}
}
else
{
echo "Nooooooob";
}
?>
I do not have the UPDATE query in place yet because I am not even sure if I am passing the JSON correctly. In the javascript click function, you see the SUCCESS and ERROR functions. All I am producing is the ERROR function in Chrome's console.
I am not sure where the error lies, in the JavaScript or the PHP.
Why can I only produce the error function in the AJAX post?
Edit
I removed the dataType in the ajax call, and added JSON.stringify to data:
$.ajax({
type: 'POST',
url: 'api/editService.php',
data: {servce: JSON.stringify(payload)},
success: function(msg){
console.log('success');
},
error: function(msg){
console.log('fail'), msg);
}
});
In the PHP script, I tried this:
if(isset($_POST['service'))
{
$json = json_decode($_POST['service'], true);
foreach ($json["service"]["sizeTypes"] as $key => $value){
$insert = mysqli_query($dbc, "INSERT INTO table (COLUMN, COLUMN, COLUMN) VALUES (".$json["service"] . ", " . "$value["id"] . ", " . $value["value"]")");
}
}
else
{
echo "noooooob";
}
With this update, I am able to get the success message to fire, but that's pretty much it. I cannot get the query to run.

without seeing the error, I suspect the error is because ajax is expecting json (dataType: 'json',) but you are echoing html in your php

Try to change
error: function(msg){
console.log('fail');
}
to
error: function(msg){
console.log(msg);
}
There might be some php error or syntax issue and you should be able to see it there.
Also try to debug your php script step by step by adding something like
echo "still works";die;
on the beginning of php script and moving it down till it'll cause error, then you'll know where the error is.
Also if you're expecting JSON (and you are - dataType: 'json' in js , don't echo any HTML in your php.

As you are sending an object in your service key, you probably have a multi-dimensional array in $_POST['service'].
If you want to send a string, you should convert the object to json:
data: {service: JSON.stringify(payload)},
Now you can decode it like you are doing in php.
Also note that you can only send json back from php if you set the dataType to json. Anything other than valid json will have you end up in the error handler.

Example how to handle a JSON response from editService.php. Typically, the editService.php script will be the worker and will handle whatever it is you need done. It will (typically) send a simple response back to the success method (consider updating your $.ajax to use the latest methods, eg. $.done, etc). From there you handle the responses appropriately.
$.ajax({
method: 'POST',
url: '/api/editService.php',
data: { service: payload },
dataType: 'json'
})
.done(function(msh) {
if (msh.success) {
console.log('success');
}
else {
console.log('failed');
}
})
.fail(function(msg) {
console.log('fail');
});
Example /editService.php and how to work with JSON via $.ajax
<?php
$response = [];
if ( isset($_POST['service']) ) {
// do your stuff; DO NOT output (echo) anything here, this is simply logic
// ... do some more stuff
// if everything has satisfied, send response back
$response['success'] = true;
// else, if this logic fails, send that response back
$response['success'] = false;
}
else {
// initial condition failed
$response['success'] = false;
}
echo json_encode($response);

ajax is calling the error function

Am working on a web application and i want to send data from a php controller to javascript and i make some research and i found that the best way to do so is by using Ajax and Json, but what i get is the error function and this is not working.
this is my php code :
$rep = $em->getRepository('LoginBundle:Note');
$note = $rep->findAll();
if ($note) {
$x=count($note);
for($i=0; $i<$x; $i++) {
$vote = $note[$i]->getReputation();
$date =$note[$i]->getDate();
$posts[$i] = array('vote' => $vote,'date'=>$date);
}
echo json_encode($posts);
and this is my script:
$.ajax({
dataType: "json",
success: function(posts){
$.each(posts, function(idx, post){
data.addRow([idx,post.vote]);
});
},
error: function(jqXHR, textStatus, errorThrown){
alert(textStatus+" error "+errorThrown);
}
});
Edit:
the error is :
parsererror error SyntaxError: unexpected >
and this is the Json response :
[{"vote":12},{"vote":14}]<!DOCTYPE html>
it looks that the probleme came from the < of <!DOCTYPE html> but i don't know ho to make the script took only the json data
any ideas??
thank you for your help

Currently you're not calling anything with AJAX, you're just saying I expect some JSON back.
$.ajax({
dataType: "json",
});
You need to specify the url.
Also... it's a general rule of thumb to terminate after you output JSON to prevent anything else being output and invalidating the JSON.
// identify that you're making a request via AJAX
$is_ajax = ( ! empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') ? true : false;
// if AJAX return JSON
if ($is_ajax)
{
echo json_encode($data);
exit(); // will terminate script at this point (before HTML)
}
// if not AJAX do your HTML return

Echo PHP message after AJAX success

I have a modal that will display when the user clicks a delete button. Once they hit the delete button I am using AJAX to subimit the form. Eveything works fine, but it is not display my success message which is set in PHP.
Here is my AJAX code:
function deleteUser(){
var id = <?php echo $userdetails['id'] ?>;
$.ajax({
type: "POST",
url: 'admin_user.php?id=' + id,
data: $('form.adminUser').serialize(),
error: function(e){
alert(e);
},
success: function () {
// This is empty because i don't know what to put here.
}
});
}
Here is the PHP code:
if ($deletion_count = deleteUsers($deletions)) {
$successes[] = lang("ACCOUNT_DELETIONS_SUCCESSFUL", array($deletion_count));
} else {
$errors[] = lang("SQL_ERROR");
}
And then I call it like this:
<div class="col-lg-12" id="resultBlock">
<?php echo resultBlock($errors,$successes); ?>
</div>
When I use AJAX it does not display the message. This works fine on other pages that does not require AJAX to submit the form.

I think you are getting confused with how AJAX works, the PHP script you call will not directly output to the page, consider the below simplified lifecycle of an AJAX request:
Main Page -> Submit Form -> Put form data into array
|
--> Send array to a script to be processed on the server
|
|----> Callback from the server script to modify DOM (or whatever you want to do)
There are many callbacks, but here lets discuss success and error
If your PHP script was not found on the server or there was any other internal error, an error callback is returned, else a success callback is fired, in jQuery you can specify a data array to be received in your callback - this contains any data echoed from your PHP script.
In your case, you should amend your PHP file to echo your arrays, this means that if a successful request is made, the $successes or $errors array is echoed back to the data parameter of your AJAX call
if ($deletion_count = deleteUsers($deletions)) {
$successes[] = lang("ACCOUNT_DELETIONS_SUCCESSFUL", array($deletion_count));
echo $successes;
} else {
$errors[] = lang("SQL_ERROR");
echo $errors;
}
You can then test you received an object by logging it to the console:
success: function(data) {
console.log(data);
}

Well, it's quite not clear what does work and what does not work, but two things are bothering me : the function for success in Ajax is empty and you have a header function making a refresh in case of success. Have you tried removing the header function ?

success: function(data) {
alert(data);
}
In case of success this would alert the data that is echoed on the php page. That's how it works.
I'm using this a lot when I'm using $.post
Your header will not do anything. You'll have to show the data on the Java script side, maybe with alert, and then afterwards redirect the user to where you want in javascript.

you need put some var in success function
success: function(data) {
alert(data);
}
then, when you read var "data" u can do anything with the text

Here is what I changed the PHP to:
if ($deletion_count = deleteUsers($deletions)) {
$successes[] = lang("ACCOUNT_DELETIONS_SUCCESSFUL", array($deletion_count));
echo resultBlock($errors,$successes);
} else {
$errors[] = lang("SQL_ERROR");
echo resultBlock($errors,$successes);
}
And the I changed the AJAX to this:
function deleteUser(){
var id = <?php echo $userdetails['id'] ?>;
$.ajax({
type: "POST",
url: 'admin_user.php?id=' + id,
data: $('form.adminUser').serialize(),
error: function(e){
alert(e);
},
success: function (data) {
result = $(data).find("#success");
$('#resultBlock').html(result);
}
});
}
Because data was loading all html I had to find exactly what I was looking for out of the HTMl so that is why I did .find.

jQuery ajax returns error but data being added to database

I'm currently trying to store data into a database via ajax.
This works fine but the ajax always returns "error" even if the php code has been executing fine.
Javascript
jQuery.ajax({
type:'POST',
url:ajaxurl,
data: { game:game, variation:variation, player:player, win:win },
success: function(data){
alert('success');
},
error: function(data) {
alert('error');
}
});
PHP
<?php
include('connectdb.php');
function addNewMatch() {
$game = $_POST['game'];
$variation = $_POST['variation'];
$date = time();
$player = $_POST['player'];
$win = $_POST['win'];
$queryMatch = "INSERT INTO pd_match VALUES (
NULL,
'".$game."',
'".$variation."',
'".$date."',
'".$player."',
'".$win."'
)";
$doQueryMatch = mysql_query($queryMatch);
if (!$doQueryMatch) { return (false); } else { echo 'success'; }
} // end function addNewMatch
addNewMatch();
?>
As I said, it works fine but ajax is returning the alert("error").
I must be missing somthing.
(It's done locally on localhost)

try this
error: function(jqXHR, textStatus, errorThrown) {
alert(textStatus, errorThrown);
}
and let us know what error you are getting.

If you are using ajax you shouldn't use
<form method="POST" action="phpfile.php">
And if you are wrapping the Ajax function inside a .on('click') or .click event your buttun should be button type button instead of button type submit, like this:
<button type="button"></button>
I havn't seen your HTML but usually when I have a problem like this it's because of that.
I hope it helps.

Return and print value passed through php script from javascript object using jquery ajax

i have the following code:
Javascript object:
var getDBresults = (function () {
function getResult(url,TableName ,callback){
$.ajax({
url: url,
type: 'POST',
data: {
'table':TableName,
},
dataType: 'json',
success: function(data){
callback(data);
console.log(data)
},
error: function(){}
});
}
return {
getAllVideoes: function(){
getResult("getAllResults.php", "videoer", function(data){
return data;
});
}
}
})();
simple php script:
<?php
$tableName = $_REQUEST['table'];
echo $tableName;
?>
My js command for fetching(seperate script ofc):
var obj = getDBresults;
var data = obj.getAllVideoes();
console.log(data)
My issue is with the callback function. It wont output anything and it doesn't seem to be running at all.. Had this issue for quite som time now and i just cant figure it out.. Is there anything i'v been missing? All help is apriciated! Sorry for my spelling btw.

you ajax is expecting
`dataType: 'json',`
json output from your php script
you are returning html/plaintext data
`echo $tableName;`
try json_encode
echo json_encode(array($tableName));
result is not in JSON format, so when jQuery fails to parse it,
You can catch the error with ajax's error: callback function
