Update a value on a entry on the table - issue

I have these columns on my table:
CardNumber
DateRegister
TimeRegister
DateExit
TimeExit
I read a value that is in a box, and when I press enter, the
Cardnumber, DateRegister,TimeRegister is add to the SQL Database
So I'll have like
CardNumber|DateRegister|TimeRegister|DateExit|TimeExit
124455|23-10-2022|11:00|null|null|
My Issue is, If I read the same card again, before I need to see if there is already one entrance on database with that card number, that don't have still DateExit and TimeExit.
If dont, I need to update that line, with that information, of if is a new one, will add a new entrance on the database
This is my code:
#section readcard{
<script>
$(function () {
$("#readONchange").change(function () {
var param1 = new Date();
var param2 = param1.getDate() + '/' + (param1.getMonth() + 1) + '/' + param1.getFullYear();
var param3 = param1.getHours() + ':' + param1.getMinutes() + ':' + param1.getSeconds();
var es = {};
/*es.IdCartao = $("#readONchange").val();*/
/*es.DateRegister = param2;*/
//Le cartao / Le data / Le Hora
es.IdCartao = $("#readONchange").val();
es.DateRegister = param2;
es.TimeRegister = param3;
if (es.IdCartao != null)
{
} else if (es.IdCartao == null) {
empregados.IdCartao = es.IdCartao(id);
(es.IdCartao == $("#readONchange").val && es.DateRegister != null && es.TimeRegister != null)
es.TimeExit = param3;
alert(es.IdCartao == $("#readONchange").val);
} else {
alert("erro")
}
alert("Register ADD!")
$.ajax({
type: "POST",
url: '#Url.Action("AddReport")',
data: '{es: ' + JSON.stringify(es) + '}',
dataType: 'json',
contentType: "application/json; charset=utf-8",
sucess: function () {
alert("Data Insert with Sucess");
},
error: function () {
alert("ERROR! on the regist");
}
});
});
});
</script>

After submit a reply by Ajax Its display a blank data space

After submit a reply without 1st post Its display a blank data space and after refresh page its show reply.
What is problem here please.
..............................................................................
This is my script
var inputAuthor = $("#author");
var inputComment = $("#comment");
var inputReplycom = $(".replycom");
var inputImg = $("#img");
var inputUrl = $("#url");
var inputTutid = $("#tutid");
var inputparent_id = $("#parent_id");
var replyList = $("#replynext");
function updateReplybox() {
var tutid = inputTutid.attr("value");
$.ajax({
type: "POST",
url: "reply.php",
data: "action=update&tutid=" + tutid,
complete: function (data) {
replyList.append(data.responseText);
replyList.fadeIn(2000);
}
});
}
$(".repfrm").click(function () {
error.fadeOut();
if (checkForm()) {
var author = inputAuthor.attr("value");
var url = inputUrl.attr("value");
var img = inputImg.attr("value");
var replycom = inputReplycom.attr("value");
var parent_id = inputparent_id.attr("value");
var tutid = inputTutid.attr("value");
$('.reply_here').hide();
$("#loader").fadeIn(400).html('<br><img src="loaders.gif" align="absmiddle"> <span class="loading">Loading Update...</span>');
//send the post to submit.php
$.ajax({
type: "POST",
url: "reply.php",
data: "action=insert&author=" + author + "&replycom=" + replycom + "&url=" + url + "&img=" + img + "&parent_id=" + parent_id + "&tutid=" + tutid,
complete: function (data) {
error.fadeOut();
$("#loader").hide();
replyList.append(data.responseText);
updateReplybox();
$("#repfrm").each(function () {
this.reset();
});
}
});
} else //alert("Please fill all fields!");
error_message();
});

Probably all this code should be inside a $(document).ready({ ... });
To debug: Open chrome inspector and put a brakepoint at this line: var tutid = inputTutid.attr("value"); and check for what is inside inputTutid variable.
Also you can try
inputTutid.val();
instead of
inputTutid.attr("value");

jQuery ajax is calling infinily , showing too much recursion error in console

I am using jQuery.validationEngine plugin .I have a below ajax function to check duplicate unique value for a field.
function _is_unique(caller) {
var value = jQuery(caller).val();
var field_id = jQuery(caller).attr('id');
var field_name = jQuery(caller).attr('placeholder');
if (value != '') {
var uniqueObject = new Object();
uniqueObject.field_id = field_id;
uniqueObject.value = value;
var uniqueString = JSON.stringify(uniqueObject);
var getUrl = window.location;
//console.log(getUrl);
var baseUrl = getUrl.protocol + "//" + getUrl.host + "/" + getUrl.pathname.split('/')[1];
jQuery.ajax({
type: "POST",
url: baseUrl + "/dashboard/check_unique",
data: uniqueObject,
async: false,
cache: false,
dataType: "text",
success: function(msg) {
if (msg == "exist") {
isError = true;
promptText += " This " + field_name + settings.allrules["is_unique"].alertText + "<br />";
}
}
});
}
}
if the field value is present in server then from server I am returnning "exist" else I am returning "notexist".
Now while running my ajax script is calling infinitely . Can any please tell me what should I do to stop infinite loop of my ajax call.
Edited
This is the form Submit function . its also showing
too much recursion
error in console. By any chance am I having problem here ?
$('#searchform').on('submit', function(e){
var validateError ='';
var id='';
var fieldError = [];
$('#searchform :input:text').each(function(){
id = $(this).attr('id');
validateError = jQuery.fn.validationEngine.loadValidation(document.getElementById(id));
if(validateError)
{ fieldError.push(id);
}
});
if(fieldError.length!=0)
{
return false;
}
else{
$("form#searchform" ).submit();
return true;
}
});
});

Ajax send image to server

I am working phonegap application. I want to send data image to server but i can not sent it.
function addSiteToServer() {
var cId = localStorage.getItem("cId");
var sname = $('#sitename').val();
var slat = $('#lat').val();
var slng = $('#lng').val();
var storedFieldId = JSON.parse(localStorage["field_id_arr"]);
var p = {};
for (var i = 0; i < storedFieldId.length; i++) {
var each_field = storedFieldId[i];
var val_each_field = $('#' + each_field).val();
p[each_field] = val_each_field;
console.log("p" + p);
}
var online = navigator.onLine;
if (online) {
var data = {
site: {
collection_id: cId,
name: sname,
lat: slat,
lng: slng,
properties: p
}
};
//function sending to server
$.ajax({
url: App.URL_SITE + cId + "/sites?auth_token=" + storeToken(),
type: "POST",
data: data,
enctype: 'multipart/form-data',
crossDomain: true,
datatype: 'json',
cache: false,
contentType: false,
processData: false,
success: function(data) {
console.log("data: " + data);
alert("successfully.");
},
}

Looks like you are using the normal method to send data/image to server which is not recommended by Phonegap/Cordova Framework.
I request you to replace your code with the following method which works as you expected,I also used local storage functionality to send values to server,
function sendDataToServer(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = {};
params.some_text = localStorage.getItem("some_text");
params.some_id = localStorage.getItem("some_id");
params.someother_id = localStorage.getItem("someother_id");
options.params = params;
var ft = new FileTransfer();
ft.upload(imageURI, encodeURI("http://example.co.uk/phonegap/receiveData.php"), win, fail, options);
}
function win(r) {
console.log("Code = " + r.responseCode+"Response = " + r.response+"Sent = " + r.bytesSent);
}
function fail(error) {
alert("An error has occurred: Code = " + error.code);
}
function saveData(){
sendDataToServer(globalvariable.imageURI);
alert("Data Saved Successfully");
}
Hope this helps.

ajax is not passing data

I dont know why this is not working. Im trying to pass data through ajax. Iv used this many times but for some reason its not working. Its returning nothing.
here is the js
$('#contactformbtn').click(function(){
var fullname = $('#fullname').val();
var youremail = $('#youremail').val();
var subject = $('#subject').val();
var yourmessage = $('#yourmessage').val();
var datastring = 'fullname=' + fullname + '&youremail=' + youremail + '&subject=' + subject + '&yourmessage=' + yourmessage;
$.ajax({
type: "POST",
url: "ajax-contact.php",
data: datastring,
success: function(status){
alert(status);
}
});
//alert(datastring);
return false;
});
and this is the php
<?php
require 'core/init.php';
if(isset($_POST)){
$fullname = $_POST['fullname'];
$youremail = $_POST['youremail'];
$subject = $_POST['subject'];
$message = $_POST['message'];
echo $fullname;
}
?>
in chrome im checking the console and im getting 2 errors
Uncaught TypeError: Cannot read property '1' of null
Uncaught TypeError: Cannot read property '3' of null
My full js is this, (just incase the error is not the contact function)
$(document).ready(function(){
$("#download-btn").bind("click", downloadfile);
$(".download-link").hide();
function downloadfile()
{
var dl = $("#dl").val();
var counter = 10;
var interval = setInterval(function(e) {
counter--;
if(counter > 0){
$("#download-btn").html("Your Download will begin in " + counter + " Seconds");
$("#download-btn").attr("disabled", "disabled");
} else {
window.location.href="http://www.forwardfiles.com/get_file.php?i="+dl;
$("#download-btn").hide();
$(".download-status").html("<h3 class='center'>Download is complete</h3>");
clearInterval(interval);
}
}, 1000);
}
$('#contactformbtn').click(function(){
var fullname = $('#fullname').val();
var youremail = $('#youremail').val();
var subject = $('#subject').val();
var yourmessage = $('#yourmessage').val();
var datastring = 'fullname=' + fullname + '&youremail=' + youremail + '&subject=' + subject + '&yourmessage=' + yourmessage;
$.ajax({
type: "POST",
url: "ajax-contact.php",
data: datastring,
success: function(status){
alert(status);
}
});
//alert(datastring);
return false;
});
});

Did you try .serialize?
$('#contactformbtn').click(function(){
$.ajax({
type: "POST",
url: "ajax-contact.php",
data: $("form").serialize(),
success: function(status){
alert(status);
}
});
//alert(datastring);
return false;
});

Check in your HTML code if these values
var fullname = $('#fullname').val();
var youremail = $('#youremail').val();
var subject = $('#subject').val();
var yourmessage = $('#yourmessage').val();
Have defined their id's and not only "name" tags

I got it working, the code i had was fine. the problem was i wasnt running php version 5.3, so i updated it and its working :D. Thanks for you help anyway
