I was updating a cakephp app from the database, suddenly it started giving me a 500 error. I explored the files I found out that it's coming from ajax code:
$(window).on("load",function(){
//Get filter by date box when page loads
$.ajax({
type:'POST',
url: "../maps/display_time_filter_box",
success: function(data){
$("#time-filter-box .dropdown-menu").html(data);
$("#mobile-time-filter-box nav").html(data);
$(".time-slider").slider({});
},
error:function(xhr){
alert("Erreur: Impossible d'afficher d'afficher le filtre");
},
cache: true
});
Do you have any idea what could be the source of the error?
I recommend use URL build to send request
url : "<?php echo $this->Url->build( [ 'controller' => 'Maps', 'action' => 'display_time_filter_box' ] ); ?>",

I'm currently building a web application using CodeIgniter 4. In one of my forms, I need ajax to send a post request and get the data result to modify the form base on item selected on a combo box.
The first requests were always okay, but it won't work for the next one. When I refresh the page, it redirects me to login page, due to my filter. It turns out that the AJAX request either destroy all my sessions, or update it to the new ones.
this is my ajax :
`
$('#penilaian_jenis').on('change', function() {
$.ajax({
OST type: "P",
url: '<?= base_url('guru/penilaian/get_nilai') ?>',
data: {
'kelas_id': '<?= $kelas->kelas_id ?>',
'kd_id': '<?= $kd->kd_id ?>',
'penilaian_jenis': $('#penilaian_jenis').val(),
},
dataType: 'json',
success: function(data) {
var result = JSON.parse(data);
alert(result);
}
})
})
`
This is my Controller :
`
public function get_nilaii()
{
echo json_encode('success');
}
`
This is how I stored my session at the auth controller:
$data = [
'user' => $user,
'guru' => $model->where('user_id', $user->user_id)->first(),
'guru_logged_in' => 1,
];
session()->set($data);
My Ajax codes I user are the simplest one. Can Anyone help give me the solutions to this problem, or recommend me another way to do HTML request without losing all my sessions?
Sorry for bad grammar, and thank you in advance
My website is built in laravel 5.4 and hosted on Siteground. The website was working fine before. But now I am randomly getting 500 internal server errors on some ajax request.
Sample code:
var csrf_token = $('meta[name="csrf-token"]').attr('content');
var postdata = {
'_token': csrf_token
};
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
url: url,
type: 'POST',
dataType: 'JSON',
data: postdata,
success: function(data) {
},
error: function(data) {
}
});
I had this problem too, randomly, in my AJAX requests, the env() function did not work.
That causes 500 errors because the application can't get config variables and i just got a message: 500 Server Error. Since i replaced the env() calls in my config files, all works fine.
So for exemple in config/app.php, this not work:
'key' => env('APP_KEY'),
But this works
'key' => 'MY_APP_KEY_HARDCODED',
Now the trick is to find why env() does not work sometimes...
I discovered the reason thanks to laravel debugbar: https://github.com/barryvdh/laravel-debugbar
This Ajax code works perfectly is I'm running the program on my local machine. However, once we put this out on a DEV server we get a 404 error. The site is an ASP MVC3 site that communicates with a SQL database, and the rest of the site has no problem doing so. I'm brand new to Ajax so I'm not quite sure where to look. Could this be an issue with IIS as well?
Ajax code
var request = $.ajax({
type: 'POST',
url: '/BatchPrograms/PopDetails',
data: { 'programName': pgmname },
dataType: 'text',
success: function (data) {
console.log(data);
alert(data);
//$('#data').dialog('open');
},
error: function (data) {
console.log(data)
alert("Unable to process your resquest at this time.");
}
});
Chrome's Console error message:
POST http://insideapps.dev.symetra.com/BatchPrograms/PopDetails 404 (Not Found)
send jquery-1.8.3.js:8434
jQuery.extend.ajax jquery-1.8.3.js:7986

Try modifying url to
url: '#Url.Action("PopDetails", "BatchPrograms")'
Try using the Url.Action() helper to get the route from the Table Routes defined in your application.
var request = $.ajax({
type: 'POST',
url: '#Url.Action("PopDetails", "BatchPrograms")',
data: { 'programName': pgmname },
dataType: 'text',
success: function (data) {
$('#data').dialog('open');
},
error: function (data) {
alert("Unable to process your resquest at this time.");
}
});
I have a problem to refresh a bloc in my page.
Here is the request:
> $("#pwd_lost_link").click(function(){
alert('1');
$.ajax({
type : 'POST',
url: 'test.php',
dataType: 'json',
data :{"nom" : "akbar"},
success : function(data){
$("#main_bloc").append(data.msg);
alert('2');
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.responseText);
alert(errorThrown); }
}); })
and here is the php file
<?php
$return['nom'] = "ffrfrfrfr";
echo json_encode($return)
?>
It doesn't work. It give me a status error ( 0 ) and the page is automatically reloaded
Thanks
Michaël
Confusing question Michael, not sure what you mean by "the page is automatically reloaded" but you should do 2 things:
In the $.ajax() method, make sure your success called back is handling the data correctly. You are looking for data.msg but I don't see where .msg comes from.
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
data: {},
dataType: "json",
url: url,
success: function(data) {
// parse data object so you can see what's being returned ex. alert(data) or alert(data[0]) or alert(data.nom)
},
error: function (xhr, status, error) {
// XHR DOM reference: http://www.w3schools.com/dom/dom_http.asp
// check for errors ex. alert(xhr.statusText);
}
});
On the PHP side, you may want to debug there to see what is being received and what you are sending back.
Aside from that using an XHR viewer like Firebug or Chrome's built-in utility (CTRL+SHIFT+I) can be very helpful.
And on a final note, if pwd_lost_link is a link elment a id="pwd_lost_link" href="..." then you will have to stop the browser from following the link before you process the AJAX.
$("#pwd_lost_link").click(function(e) {
e.preventDefault();
alert('1');
$.ajax({
...
});
If you aren't seeing the '1' being alerted then that is definitely your first problem.
You're trying to access data.msg, but your PHP script is only creating data.nom. So data.msg doesn't exist. Try changing data.msg to data.nom and see if this does what you want.
I am trying to receive a json object back from php after sending data to the php file from the js file.
All I get is undefined.
Here are the contents of the php and js file.
data.php
<?php
$action = $_GET['user'];
$data = array( "first_name" => "Anthony",
"last_name" => "Garand",
"email" => "anthonygarand#gmail.com",
"password" => "changeme");
switch ($action) {
case 'anthonygarand#gmail.com':
echo $_GET['callback'] . '('. json_encode($data) . ');';
break;
}
?>
core.js
$(document).ready(function(){
$.ajax({ url: "data.php",
data: {"user":"anthonygarand#gmail.com"},
context: document.body,
data: "jsonp",
success: function(data){renderData(data);}
});
});
function renderData(data) {
document.write(data.first_name);
}
It looks like you have two data options set in the Ajax function. Instead of the line
data: "jsonp",
You need
dataType: "jsonp"
As you're not actually passing the PHP file any information.
Another couple of things, make sure you're getting valid JSON (jsonlint.com), we had a similar issue and it turned out we had the wrong kind of quotes.
Lastly: You MAY need to JSON.parse(data) to see convert it to an object at Javascript's end.
