Good day. I'm working on a admin page basically it is a content management system. I want to delete the data based on their id. But unfortunately i've encounter a error on the htpp request. here is the error.
Request URL: admin/ajax_delete
Request Method:POST
Status Code:500 Internal Server Error
Remote Address:144.76.136.165:8181
VIEW FILE:
<span class="glyphicon glyphicon-trash"></span>
$("#delete_tpi").click(function() {
alert("Are you sure you want to delete?");
var tpi = $('.datatpi').val(); //package includes
var did = $('#data-id').val();
$.ajax({
url: '<?php echo site_url('admin/ajax_delete'); ?>',
type: 'POST',
datatype: 'html',
data: {id: did, tpi: tpi},
success:function (b){
if (b == 'Success') {
$('.#data-id').val('');
$('.datatpi').val('');
location.reload();
}
}
});
});
$('body').on('click','.edit-content-modal',function(){
var id = $(this).attr('data-id');
$('#data-id').val(id);
});
Controller file:
public function ajax_delete(){
$did = $this->input->post('id');
$ptpi = $this->input->post('tpi');
$update = $this->products_model->row_delete($did,$ptpi);
var_dump($update);
echo ($update)?'Success':'Fail';
}
MODEL FILE:
function ajax_delete($did,$ptpi){
$this->db->where('id',$did);
$this->db->delete('products',$ptpi);
return $this->db->affected_rows() > 0;
}
Because <a></a> element does not expect a value tag. You can get the ID of the clicked #delete_tpi link by using attr():
var did = $("#delete_tpi").attr('data-id');
Your POST request to admin/ajax_delete returns 500 Internal Server Error. This is a server-side error. If you use codeigniter, take a look at application/logs/*.log files that will give you detail information about the error.
I think, your problem is calling a non-existing function from model:
In your controller, you have:
$this->products_model->row_delete($did,$ptpi);
But your model, contains:
function ajax_delete($did,$ptpi){
....
}
Do you have row_delete() function in your model?
Once again, i suggest you to look at logs file, because many problems can result in server-side error.

I have error ->
"Failed to load resource: the server responded with a status of 405
(Method Not Allowed)"
when send Ajax data to PHP in larval.
(I made route)
Ajax code
function insertData()
{
var text = document.getElementById('humanText').value;
var user = document.getElementById('userName').innerText;
$.ajax({
type:"POST",
url: "insertContentData",
data:{text:text, user:user},
success: function(data){
alert(data);
}
});
document.getElementById('humanText').value = "";
};
insertData();
and my php code "insertContentData.php"
<?php
$data = $_POST['text'];
$user = $_POST['user'];
echo $data.", ".$user;
?>
why not work this?
Thanks for your help.
In the http world the "METHOD" normally used is "GET" which is simply pulling data from the server. When you want to send data from the user to the server you used "POST". These are the two most commonly used methods.
The errors says that the METHOD IS NOT ALLOWED. You are AJAX code shows that you are using the POST method.
In Laravel you need to define a route that allows for the POST method. So instead of Route::get($uri, $callback); it would be Route::post($uri, $callback); Some more information can be found in the Laravel Routing documentation. However I think you are missing some concepts based on the primitive PHP code you posted, that code should be inside a controller.
Try to run like this. I hope it works.
function insertData(){
var text = document.getElementById('humanText').value;
var user = document.getElementById('userName').innerText;
$.ajax({
type:"POST",
url: "insertContentData",
data:{text:text, user:user},
success: function(data){
alert(data);
}
});
document.getElementById('humanText').value = "";
};
window.onload = function(){
insertData();
}
<?php
$data = $_POST['text'];
$user = $_POST['user'];
echo $data.", ".$user;
?>
I' m using cms ModX and want to send Ajax request to server using post method. The problem is that the post data of the second, the third and so one requests doesn't change and remains the same as in the first request.
To clarify the situation I provide the following example.
The javascript is the following:
var reqCount = 0;
$(document).ready(function () {
$(window).scroll(function() {
var dataToPost = {'reqCount' :reqCount};
$.ajax({
url: 'http://example.com/ajaxTest',
method: 'POST',
data: dataToPost,
dataType:"json",
success: function(data){
ajaxCountFromServer = data['ajaxCount'];
reqCount=reqCount+1;
}
});
}
}
Also I created resource with address http://example.com/ajaxTest in Modx with the code, running the snippet:
[[getAJAX]]
getAJAX snippet is the following:
<?php
if ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest') {
$reqCount = $_REQUEST['reqCount'];
$json_obj = array("ajaxCount" =>$reqCount);
return json_encode($json_obj);
}
?>
So, after the first scroll reqCount=0, it's passed to server and after the server responses(success callback) ajaxCountFromServer=0 and reqCount=1. There all works well.
However, after the second scroll reqCount=1 and after the server response ajaxCountFromServer=0,but it should be 1.
How to fix it?
The solution is quite simple. In the page customizing of the resource http://example.com/ajaxTest, where snippet getAJAX is called, I just unchecked the checkbox "Cacheable".
The correct way to do it is
[[!getAJAX]]
The snippet is not cached now
I've made an ajax call with this:
$('.start-rate-fixed').on('click', function(e){
e.preventDefault();
var videoRate = $('.start-rate input[name="rating"]:checked').val(),
productId = parseInt($('.popover-content').prop('id'));
$.ajax({
url : ROOT + 'products/rate_video',
type : 'POST',
data : {
'data[Product][id]' : productId,
'data[Product][success_rate]' : videoRate
}
}).done(function(res){
var data = $.parseJSON(res);
alert(data);
});
});
Where I defined ROOT as the webroot of my cakephp project in my default.ctp with this:
<script type="text/javascript">
var ROOT = '<?php echo $this->Html->url('/');?>';
</script>
and trying to retrieve data from a function "rate_video" defined in my products controller but I get this error. Also I've tried a simple ajax for a test function but it showed me the same issue.
Controller Code
public function rate_video(){
$this->autoRender = false;
if($this->request->is('post') && $this->request->is('ajax')){
$success_rate = $this->request->data['Product']['success_rate'];
$this->Product->id = $this->request->data['Product']['id'];
if($this->Product->saveField('success_rate', $success_rate)){
echo json_encode('Successfully Rated');
} else {
echo json_encode('Error!!');
}
}
}
Please add dataType and a forward slash (/) at the end of your request URL
$.ajax({
url : ROOT + 'products/rate_video/',
type : 'POST',
data : {
'data[Product][id]' : productId,
'data[Product][success_rate]' : videoRate
},
dataType: 'json',
}).done(function(res){
I just had the same problem and solved it by putting the URL within AJAX call to a URL that I know works. Then try accessing the URL that you are trying to invoke via AJAX directly within the web browser - most likely you are accessing a controller that does not have a view file created. To fix this you have to ensure that the controller method being accessed does not have a view to be rendered - set $this->render(null)
If you have incorrect url then
url: '<?php echo Router::url(array('controller' => 'Controllername', 'action' => 'actionname')); ?>'
this above url provide ajax to url from root to your action.
And other cause for 403 is your auth function, if your using auth in your controller then make your ajax function allow like
$this->Auth->allow('Your ajax function name here');
Your script placed at localhost/dev.popover/products/rate_video but ajax ROOT is / - that mean localhost/ and ajax sent request to
'localhost/products/rate_video'
Right solution is
<script type="text/javascript">
var ROOT = '<?php echo $this->Html->url('/dev.popover/');?>';
</script>
At this moment I am using laravel. In this context I am having a form which is successfully submitted by using ajax to a controller. and that controller make it to the database. But the problem is as the ajax is doing its job the whole page remain unmoved / unchanged after the submission even the database is updated.
Now what I want
I want to give feedback to the user that your post is successfully submitted there. or what I want to do in further, I want to refresh the section in which the post is collected from the database as this post can be retrieved from there. But by using ajax only.
So there is no need to collect the whole page or refresh.
here is my form structure
`
{{ Form::open(array('route' => array('questions.store'), 'class' => 'form-horizontal' )) }}
blah blah blaaa .......
<script type="text/javascript">
$(".form-horizontal").submit(function(e){
$(this).unbind("submit")
$("#ask").attr("disabled", "disabled")
var that = $(this),
url = that.attr('action'),
type = that.attr('method'),
data = {};
that.find('[name]').each(function(index, value){
var that = $(this),
name = that.attr('name'),
value = that.val();
data[name] = value;
});
$.ajax({
url: url,
type: type,
data: data,
success: function(response){
console.log(response);
}
});
return false;
});
</script>
{{ Form::close() }}
`
As it is very much visible that the post is updated through a route & controller I want to have another dive and a success message at this script to be displayed after the success of posting. I am looking for some professional structure using what there is minimal need to have interaction with the server side and give user a better page viewing experience.
Thanks a lot for helping me in this research.
I am not sure if I understand you well, but if you want to notify the user about the result of an ajax-called db update you need to have
a route for the ajax save db call - it should point to a method that does the db update.
the db update method should return some value indicating the success/failure of update (for example OK or FAIL)
the only result of calling the method will be just plain text page with OK or FAIL as body
fetch the result by ajax and inform user accordingly (after form submit button)
check out the below code for ajax call itself (inside the form submit handler) to see what I mean
var db_ajax_handler = "URL_TO_YOUR_SITE_AND_ROUTE";
var $id = 1; //some id of post to update
var $content = "blablabla" //the cotent to update
$.ajax({
cache: false,
timeout: 10000,
type: 'POST',
tryCount : 0,
retryLimit : 3,
url: db_ajax_handler,
data: { content: $content, id: $id }, /* best to give a CSRF security token here as well */
beforeSend:function(){
},
success:function(data, textStatus, xhr){
if(data == "OK")
{
$('div.result').html('The new Question has been created');
}
else
{
$('div.result').html('Sorry, the new Question has not been created');
}
},
error : function(xhr, textStatus, errorThrown ) {
if (textStatus == 'timeout') {
this.tryCount++;
if (this.tryCount <= this.retryLimit) {
//try again
$.ajax(this);
return;
}
return;
}
if (xhr.status == 500) {
alert("Error 500: "+xhr.status+": "+xhr.statusText);
} else {
alert("Error: "+xhr.status+": "+xhr.statusText);
}
},
complete : function(xhr, textStatus) {
}
});
EDIT: as per comment, in step 2 (the method that is called with AJAX) replace
if($s)
{
return Redirect::route('questions.index') ->with('flash', 'The new Question has been created');
}
with
return ($s) ? Response::make("OK") : Response::make("FAIL");
EDIT 2:
To pass validation errors to the ajax-returned-results, you cannot use
return Response::make("FAIL")
->withInput()
->withErrors($s->errors());
as in your GIST. Instead you have to modify the suggested solution to work on JSON response instead of a plain text OK/FAIL. That way you can include the errors in the response and still benefit from the AJAX call (not having to refresh the page to retrieve the $errors from session). Check this post on the Laravel Forum for a working solution - you will get the idea and be able to fix your code.
NOTE:
I gave up on trying to do the processing in one go, and just let it return after every x number of sends.
Two paths,
/sms?action=send
/sms?action=status
Let's say that the send path starts sending 10,000 sms messages via REST api calls.
I make a call to that page via ajax.
Then every few seconds, I make a call to /sms?action=status to see how the progress is going, and to update a progress bar.
The status path returns false if no messages are being sent.
What ends up happening is that the ajax call to the SEND path gets the ajax success: function called almost instantly, even though I know the script is taking 1+ minute to complete execution.
My progress bar never gets shown because the status ajax call (which is in a set interval with a few second delay) never seems to actually get called until the send call completes.
I'm trying to put the relevant code in here, but it may not be as clear as it should be without all the context.
<script type="text/javascript">
var smsInterval = 0;
var smsSending = false;
$(document).ready(function() {
var charCount = 0;
var smsText = "";
var smsTotal = <?php echo $options["smsTotal"]; ?>;
<?php if($options["sending"]): ?>
smsStatus();
smsSending = true;
smsInterval = setInterval("smsStatus()", 5000);
<?php endif; ?>
$("span#smsadmin_charcount").html(charCount.toString());
//send button
$("div#smssend").click(function() {
if(smsSending == true) {
return false;
}
smsStatus();
var dataString = $("#smsadmin_form").serialize();
smsSending = true;
$("div#smssend").html("Sending...");
$.ajax({
type: "POST",
url: "<?php echo $base_url; ?>/admin/sms",
data : dataString,
success: function(data) {
},
error: function(request, error) {
$("div.notice.sms").html("ERROR "+error+ "REQUEST "+request);
}
});
});
});
function smsStatus() {
var dataString = "smsaction=status&ajax=true";
$.ajax({
type: "POST",
url: "<?php echo $base_url; ?>/admin/sms",
data : dataString,
success: function(data) {
//data being false here indicates the process finished
if(data == false) {
clearInterval(smsInterval);
var basewidth = $("div.sms_progress_bg").width();
$("div.sms_progress_bar").width(parseInt(basewidth));
$("div.sms_progress_notice").html(parseInt(100) + "% Complete");
smsSending = false;
$("div#smssend").html("Send To <?php echo $options["smsTotal"]; ?> Recipients");
} else {
var pcomplete = parseFloat(data);
$("div.sms_progress_bg").show();
var basewidth = $("div.sms_progress_bg").width();
$("div.sms_progress_bar").width(parseInt(basewidth * pcomplete));
$("div.sms_progress_notice").html(parseInt(pcomplete * 100) + "% Complete");
}
},
error: function(request, error) {
$("div.notice.sms").html("ERROR "+error+ "REQUEST "+request);
}
});
}
I might be missing the point, but inside the $("div#smssend").click you got this line:
smsStatus();
shouldn't it be:
smsInterval = setInterval("smsStatus()", 5000);
and INSIDE the success: function(data) for /admin/sms ?
If the send part is sending out 10k messages, and the status returns true if currently sending a message, and false if in between sending, then you have a design issue.
For example, what is status supposed to be showing?
If status is to show how many of a certain block have been sent, then what you can do is to submit the message to be sent (or addresses), and get back some id for that block.
Then, when you ask for a status, pass the id, and your server can determine how many of that group has been sent, and return back the number that were successful, and unsuccessful, and how many are still pending. If you want to get fancy, you can also give an indication how much longer it may be before finishing, based on how many other requests are also pending.
But, how you approach this really depends on what you expect when you ask for the status.
