Ajax response not returning - php

Question

I am having a table with data where I have an action button in last column to delete that particular row. I want to make the delete via ajax and without refreshing the page. I am using the following code but their is no response coming from the ajax page. Also the queries at the ajax page is not executing. Can I have some insight over what could be possibly wrong.
<script type="text/javascript" >
$(function() {
$(".delbutton").click(function() {
var del_id = $(this).attr("id");
var info = 'id=' + del_id;
var $tr = $(this).closest('tr');
if (confirm("Sure you want to delete this post? This cannot be undone later.")) {
$.ajax({
type : "POST",
url : "delete_entry.php", //URL to the delete php script
data: info,
success : function(response) {
if(response=='deletion success'){
$tr.find('td').fadeOut(1000,function(){ $tr.remove(); });
}
}
});
}
return false;
});
});
</script>
And at delete_entry.php
<?php
header('Content-Type: application/json');
session_start();
require("../config.php");
require("../Database.class.php");
require("../site.php");
$db = new Database(DB_SERVER, DB_USER, DB_PASS, DB_DATABASE);
$fnc=new site_functions($db);
$id = $_POST['id'];
$deleted_date = date("Y-m-d h:i:s");
$deleted_by = $_SESSION['session_admin_id'] ;
$nots = $db->idToField("tbl_ques","notes",$id);
if ($nots == "")
{
$date_string = "last deleted on|".$deleted_date."|" ;
}
else {
$date_string = $nots."last deleted on|".$deleted_date."|" ;
}
$fnc->update_is_not_deleted_for_Pearsonvue("tbl_ques",$id, "$deleted_date", $deleted_by);
$notes_data = array("notes"=>$date_string);
if($db->query_update("tbl_ques", $notes_data, "id=$id")){
http_response_code();
echo json_encode('deletion success');
}else{
http_response_code(204);
}
?>

Change your java script function as below
<script type="text/javascript" >
$(function() {
$(".delbutton").click(function() {
var del_id = $(this).attr("id");
var info = 'id=' + del_id;
if (confirm("Sure you want to delete this post? This cannot be undone later.")) {
$.ajax({
type : "POST",
url : "delete_entry.php", //URL to the delete php script
data: info,
//changes from
success : function(response) {
if(response=='deletion success'){
$(this).parents(".record").animate("fast").animate({
opacity : "hide"
}, "slow");
}
}
});
//changes to
}
return false;
});
});
</script>
Also change you php file
<?php
header('Content-Type: application/json'); // Add this line its must
session_start();
$db = new Database(DB_SERVER, DB_USER, DB_PASS, DB_DATABASE);
$id = $_POST['id'];
$deleted_date = date("Y-m-d h:i:s");
$deleted_by = $_SESSION['session_admin_id'] ;
$nots = $db->idToField("tbl_question","notes",$id);
if ($nots == "")
{
$date_string = "last deleted on|".$deleted_date."|" ;
}
else {
$date_string = $nots."last deleted on|".$deleted_date."|" ;
}
$fnc->update_is_not_deleted_for_Pearsonvue("tbl_question",$id, "$deleted_date", $deleted_by);
$notes_data = array("notes"=>$date_string);
//changes from
if($db->query_update("tbl_question", $notes_data, "id=$id")){
http_response_code();
echo json_encode('deletion success');
}else{
http_response_code(204);
}
//changes to
?>
