Ajax undefined value in PHP

When I call the function I always get an undefined value, I don't understand what can ruin it.
You are logged in as undefined, Error undefined
Ajax script:
function Submit() {
console.log('asd')
$.ajax({
url: "Server.php",
type: "POST",
dataType: "json",
data: {
name: "Test2",
email: "Test#gmail.com"
},
success: function(data, textStatus, jqXHR) {
console.log("You are logged in as: ", data.name);
$('#user').html("You are logged in as: " + data.name);
},
error: function(request, error, data) {
console.log(arguments);
alert(" Can't do because: " + error + " DATA: " + data);
}
})
}
PHP Script:
<?php
header("Content-type: application/json; charset=utf-8");
$errors = [];
$data = [];
if (empty($_POST['name'])) {
$errors['name'] = 'Name is required.';
}
if (empty($_POST['email'])) {
$errors['email'] = 'Email is required.';
}
if (!empty($errors)) {
$data['success'] = false;
$data['errors'] = $errors;
} else {
$data['success'] = true;
$data['message'] = 'Success!';
$data['name'] = $_POST['name'];
}
echo json_encode($data);
?>
I tried every solution in vain, so I still get an indefinite value. I’m slowly starting to think there’s nothing wrong with the script.

You want to use data.name but you never return name. hence the undefined.
I've added data.name in the example below and it seems to work fine.
<?php
header("Content-type: text/html; charset=utf-8");
$errors = [];
$data = [];
if (empty($_POST['name'])) {
$errors['name'] = 'Name is required.';
}
if (empty($_POST['email'])) {
$errors['email'] = 'Email is required.';
}
if (!empty($errors)) {
$data['success'] = false;
$data['errors'] = $errors;
} else {
$data['success'] = true;
$data['message'] = 'Success!';
$data['name'] = $_POST['name'];
}
echo json_encode($data);
?>
Also the parameters used in the succes function are in a different order than you seem to use, in your case the request will have your data in it

the callback parameter not
success:function(request, data, error)
but
success: function(data, textStatus, jqXHR)
data.name of course undefined because it is string
and your Server.php return this
{"success":true,"message":"Success!"}
no data.name but data.success and data.message
so you have to write
if (!empty($errors)) {
$data['success'] = false;
$data['errors'] = $errors;
} else {
$data['success'] = true;
$data['message'] = 'Success!';
$data['name'] = $_POST['name']; // add this
}

Bootstrap treeview nodes do not expand

I have a problem with a specific bootstrap treeview, I have tried everything but the node does not expand, I use ajax request through a load file where I retrieve the information coming from the database, the data appears normally, the only one I have already tried all the methods that the treeview bootstrap provides, but it returns that it does not know the method used, below I will send the specific code that I use.
Function that calls a tree:
var levelTree = 2;
function getTree() {
var data = '';
$.ajax({
url: 'atividades/atividades_load.php',
data: {idObraAtiva: <?php echo $idObra; ?>},
async: false,
dataType: 'json',
type: 'post',
beforeSend: function () {
},
success: function (retorno) {
data = retorno;
console.log(retorno);
},
error: function () {
bootbox.alert('Erro, contate o suporte!');
}
});
return data;
}
$('#atividadeTree').treeview({
data: getTree(),
levels: levelTree,
backColor: "#C4E3F3",
onNodeSelected: function (event, data) {
if (data.qtdfilhos == 0) {
$('#table_Andamento').bootstrapTable('refresh', {url: 'atividades/atividade_andamento_load.php?q=' + data.id});
}
$('#table_AtividadeFilha').bootstrapTable('refresh', {url: 'atividades/atividade_filha_load.php?p=' + data.id});
$('#fmAndamento_idatividade').val(data.id);
$('#fmAtividadeSub_idAtividade').val(data.id);
},
onNodeExpanded: function (event, data) {
$.ajax({
url: 'atividades/atividades_load.php',
data: {idObraAtiva: <?php echo $idObra; ?>,idNo:data.id},
async: false,
dataType: 'JSON',
type: 'POST',
beforeSend: function (){
},
success: function (filho){
$('#atividadeTree').treeview('addNode',[filho, data.id,
{silent: false} ]);
console.log(filho);
},
error: function () {
bootbox.alert('Erro, contate o suporte!');
}
});
}
});

AJAX - JSON Error

When I am trying to receive data from the server side, error I am getting:
06-30 11:23:57.119: I/chromium(7486): [INFO:CONSOLE(50)] "{"readyState":4,"responseText":"","status":404,"statusText":"Not Found"}", source: file:///android_asset/www/js/index.js (50)

async: false,
success: function (response){
//alert ("response");
//alert(JSON.stringify(response));
//console.log(JSON.stringify(response));
if (response.success) {
myApp.alert("you're logged in");
//window.localStorage["email"] = e;

error: function(error){
//alert(response.success);
//myApp.alert('Could not connect to the database' + error);
console.log(JSON.stringify(error));
//window.location = "index.html";

});
PHP side:
$sql = "SELECT login_id, email_id, password FROM login WHERE email_id='$myusername' and password='$mypassword'";
$result = mysql_query($sql);
$num_rows = mysql_num_rows($result);
$row = mysql_fetch_array($result);
if($num_rows == 1) {
$response['success'] = true;
}else {
$response['success'] = false;
}
echo json_encode($response);

Ajax 200 Success/failed execution

I have an issue with ajax and I am kinda new at this. The issue that I am having is even if log in fails ajax is still running the success block of code. How do I direct the code to return a failed status.
I'm not asking for you to inspect my code just more as a reference. I just need to know how to tell my code to send anything other than a 200 for okay so that I can display the errors on the screen.
I type in false information and the ajax thinks that the login happened but it really didn't.
AJAX Section
jQuery(document).ready(function(){
document.body.style.paddingTop="3px";

return false;
});
var methods = {

You can add below code for ajax error section ..in this way you will get idea of what's exactly is error and can debug it.
error:
function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
}

Use the PHP header function.
header('HTTP/1.0 403 Forbidden'); // or whatever status code you want to return.
There can be nothing else outputted before using the header function.
