echo query on ajax response - php

I'm trying to send a php form data via AJAX (without the refresh) and display data in new form. I echo query but it didnt work. On AJAX response it shows me getReportAj form on call.The code goes like this:
Javascript
function getReport()
{
var dataString = "grNo=" +$(".grNo").val();
$.ajax({
type: "GET",
url: "getReportAj.php",
data: dataString,
success:function(data)
{
$('#result').html(data);
}
});
}
getReportAj.php
<?php
include "include/config.inc.php";
if(!isset($_SESSION['s_activName']) && !isset($_SESSION['s_userType']) || isset($_SESSION['s_userType']) && $_SESSION['s_userType'] == 'Student') {
$_SESSION['s_urlRedirectDir'] = $_SERVER['REQUEST_URI'];
header("Location:checkLogin.php");
}
else {
if(isset($_REQUEST['submit'])) {
$selectReport = "SELECT * from gradeterm1
WHERE studentId = ".$_POST['studentId']."
AND termValue = 1
LEFT JOIN studentmaster ON studentmaster.studentId = gradeterm1.studentId";
$selectReportRes = mysql_query($selectReport);
if($reportRow = mysql_fetch_array($selectReportRes)); {
$eReadingPro = $reportRow['eReadingPro'];
$eReadingFlu = $reportRow['eReadingFlu'];
$eReadingCom = $reportRow['eReadingCom'];
$eWritingCre = $reportRow['eWritingCre'];
$eWritingHan = $reportRow['eWritingHan'];
$eWritingGra = $reportRow['eWritingGra'];
$eWritingSpe = $reportRow['eWritingSpe'];
$eWritingVoc = $reportRow['eWritingVoc'];
$ewSpeakinCon = $reportRow['ewSpeakinCon'];
$ewSpeakinRec = $reportRow['ewSpeakinRec'];
$ewSpeakinCla = $reportRow['ewSpeakinCla'];
$eListingComp = $reportRow['eListingComp'];
$eListingCon = $reportRow['eListingCon'];
$extraReading = $reportRow['extraReading'];
$activityPro = $reportRow['activityPro'];
$hiReadingPro = $reportRow['hiReadingPro'];
$hiReadingFlu = $reportRow['hiReadingFlu'];
$hiReadingCom = $reportRow['hiReadingCom'];
$hiWritingCre = $reportRow['hiWritingCre'];
$hiWritingHan = $reportRow['hiWritingHan'];
$hiWritingGra = $reportRow['hiWritingGra'];
$hiWritingSpe = $reportRow['hiWritingSpe'];
$hiWritingVoc = $reportRow['hiWritingVoc'];
$hiwSpeakinCon = $reportRow['hiwSpeakinCon'];
}
}
}
include("./bottom.php");
$smarty->display('getReportAj.tpl');
?>

<script>
function getReport()
{
var dataString = "grNo=" +$(".grNo").val();
$.ajax({
type: "GET",
url: "getReportAj.php",
data: dataString,
success:function(data)
{
$('#result').html(data);
console.log(data);
}
});
}
</script>
in success event.. put the console.log(data) then run the script and check in console.

Data missing when sent via AJAX

I want to send two values to my PHP script that is being called from an AJAX request. Somehow my data is not being passed to the PHP script.
Maybe I am doing something wrong somewhere. Can I have some insight?
$(function() {
$(".delbutton").click(function() {
var viewed_comments = $("#viewed_comments").val();
var del_id = $(this).attr("id");
var info = 'id=' + del_id;
var comments = 'comm=' + viewed_comments;
var tr = $(this).closest('tr');
if (confirm("Are you sure to mark this as viewed?")) {
$.ajax({
type : "POST",
url : "update_entry.php",
dataType: "json",
data: {info:info, comments:comments },
success : function(response) {
if(response=="updation success"){
console.log('inside');
}
}
});
}
return false;
});
});
And my PHP where the AJAX request is going,
$id = $_POST['id'];
$viewed_comments = $_POST['comm'];
$level_code = $_SESSION['level_code'];
$action = 'view';
$viewed_date = date("Y-m-d");
$viewed_by = $_SESSION['session_admin_id'] ;
if($action == 'view')
{
$viewed_date = date('Y-m-d h:i:s');
$nots = $db->idToField("tbl_table","notes",$id);
if ($nots == "")
{
$date_string = "last viewed on|".$viewed_date."|" ;
}
else {
$date_string = $nots."last viewed on|".$viewed_date."|" ;
}
$fnc->update_is_viewed_for("tbl_table",$id, "$viewed_date", $viewed_by);
$notes_data = array("notes"=>$date_string,"viewed_comments"=>$viewed_comments);
$db->query_update("tbl_table", $notes_data, "id=$id");
}
if($db->query_update("tbl_table", $notes_data, "id=$id")){
http_response_code();
echo json_encode('updation success');
}else{
http_response_code(204);
}
Isn't it a name thing? You send two POST variables:
data: {
info: info,
comments: comments
},
but you retrieve them with different names:
$id = $_POST['id'];
$viewed_comments = $_POST['comm'];
What do you get if you var_dump($_POST);?
Use seriliaze form values it will solve your data missing problem, change #frm to your form id
$(document).ready(function(){
$('#frm').submit(function(event){
event.preventDefault();
var formValues = $(this).serialize();
$.ajax({
url:"update_entry.php",
method:"POST",
data:formValues,
dataType:"JSON",
success:function(data){
if (data == 'updation success') {
console.log('success');
}
}
});
});
});

e.preventDefault / return false breaks ajax script firing properly

I'm creating an ajax script to update a few fields in the database. I got it to a point where it worked but it sent the user to the php script instead of staying on the page so I did some googling, and people suggested using either return false; or e.preventDefault() however, if I do this, it breaks the php script on the other page and returns a fatal error. I might be missing something being newish to AJAX but it all looks right to me
JS:
$(document).ready(function() {
var form = $('form#edit_child_form'),
data = form.serializeArray();
data.push({'parent_id': $('input[name="parent_id"]').val()});
$('#submit_btn').on('click', function(e) {
e.preventDefault();
$.ajax({
url: form.prop('action'),
dataType: 'json',
type: 'post',
data: data,
success: function(data) {
if (data.success) {
window.opener.$.growlUI(data.msg);
}
},
error: function(data) {
if (!data.success) {
window.opener.$.growlUI(data.msg);
}
}
});
});
})
AJAX:
<?php
//mysql db vars here (removed on SO)
$descriptions = $_GET['descriptions'];
$child_id = $_GET['child_id'];
$parent_id = $_GET['parent_id'];
$get_child_ids = $dbi->query("SELECT child_ids FROM ids WHERE parent = ". $parent_id ." ORDER BY id"); //returns as object
$count = 0;
$res = array();
while ($child_row = $get_child_ids->fetch_row())
{
try
{
$dbi->query("UPDATE ids SET description = '$descriptions[$count]', child_id = '$child_id[$count]' WHERE parent_id = $child_row[0]");
$res['success'] = true;
$res['msg'] = 'Success! DDI(s) updated';
} catch (Exception $e) {
$res['success'] = true;
$res['msg'] = 'Error! '. $e->getMessage();
}
$count++;
}
echo json_encode($res);
it's probably something really small that I've just missed but not sure what - any ideas?
my solution:
I var_dumped $_GET and it returned null - changed to $_REQUEST and it got my data so all good :) thanks for suggestions
Try the following instead.
I moved the form data inside click and enclosed the mysql queries values in single quotes.
JS:
$(document).ready(function() {
var form = $('form#edit_child_form');
$('#submit_btn').on('click', function(e) {
e.preventDefault();
var data = form.serializeArray();
data.push({'parent_id': $('input[name="parent_id"]').val()});
$.ajax({
url: form.prop('action'),
dataType: 'json',
type: 'get',
data: data,
success: function(data) {
if (data.success) {
window.opener.$.growlUI(data.msg);
}
},
error: function(data) {
if (!data.success) {
window.opener.$.growlUI(data.msg);
}
}
});
});
})
AJAX:
<?php
//mysql db vars here (removed on SO)
$descriptions = $_GET['descriptions'];
$child_id = $_GET['child_id'];
$parent_id = $_GET['parent_id'];
$get_child_ids = $dbi->query("SELECT child_ids FROM ids WHERE parent = '". $parent_id ."' ORDER BY id"); //returns as object
$count = 0;
$res = array();
while ($child_row = $get_child_ids->fetch_row())
{
try
{
$dbi->query("UPDATE ids SET description = '$descriptions[$count]', child_id = '$child_id[$count]' WHERE parent_id = '$child_row[0]'");
$res['success'] = true;
$res['msg'] = 'Success! DDI(s) updated';
} catch (Exception $e) {
$res['success'] = true;
$res['msg'] = 'Error! '. $e->getMessage();
}
$count++;
}
echo json_encode($res);
You are using an AJAX POST request so in your PHP you should be using $_POST and not $_GET.
You can just change this:
$descriptions = $_GET['descriptions'];
$child_id = $_GET['child_id'];
$parent_id = $_GET['parent_id'];
to this:
$descriptions = $_POST['descriptions'];
$child_id = $_POST['child_id'];
$parent_id = $_POST['parent_id'];

Ajax post not passing data to php?

So I'm having trouble with passing data using ajax post to php
Here is my jquery :
$('#kodeobat').on('change',function(){
var kodeobat = $(this).val();
if (kodeobat = ""){
$("#hargaobat").val("");
} else {
$.ajax({
type: "POST",
data: { 'kodeobat': kodeobat },
dataType: "json",
url: "getdata.php",
success: function(json) {
$("#hargaobat").val(json["hargaobat"]);
}
});
}
});
and here is the php file:
$kodeobat = $_POST['kodeobat'];
$stmt = $db_con->prepare("SELECT kodeobat, hargaobat FROM Obat WHERE kodeobat='".$kodeobat."'");
$stmt->execute();
while($row=$stmt->fetchAll(PDO::FETCH_ASSOC))
{
if($kodeobat == $row['kodeobat']){
echo json_encode($row);
}
}
and it results : Notice: Undefined index: kodeobat in .../getdata.php on line 4 which is this line $kodeobat = $_POST['kodeobat'];
Is there something wrong with the code? Thank youuu :)
$('#kodeobat').on('change',function(){
var kodeobat = $(this).val();
if (kodeobat == ""){
$("#hargaobat").val("");
} else {
$.ajax({
type: "POST",
data: { 'kodeobat': kodeobat },
dataType: "json",
url: "getdata.php",
success: function(json) {
$("#hargaobat").val(json["hargaobat"]);
}
});
}
});
Notice if (kodeobat == "")
Try sending your JSON as JSON by using PHP's header() function:
header("Content-Type: application/json", true);
look at this
If you are unaware of what type of value you would get in response here is a try..
$kodeobat = $_POST['kodeobat'];
if(empty($kodeobat)) {
echo("Value is empty");
} else if(is_array($kodeobat)) {
$i = count($kodeobat); //If the value is array iterate it
for($j = 0; $j < $i; $j++) {
echo($kodeobat[$i] . " ");
}
} else if(is_object($kodeobat)){
$json = json_decode($_POST,true); //if it is a json value decode it
$kodeobat_new = $json['kodeobat'];
}

Ajax response return undefined

Hi I have been using ajax for many times. But I can't figure out whats the problem with my code this time. My head is blowing up since 2 days. I am using pusher for the realtime notification in CodeIgniter. Here's my code.
$(document).on("click", ".myonoffswitch", function () {
if (confirm("Sure!!! You want to Change the post status?"))
{
var thiss = $(this);
var prod_id = $(this).attr('id');
var status = $(this).attr('value');
var tdid = $(this).parent().prev().attr('class');
var td = $(this).parent().prev();
var adsstatus = $.ajax({type: "POST", dataType: "json", url: base_url + 'init/ads_status', data: {'prod_id': prod_id, 'status': status}});
$.when(adsstatus).done(function (adsstatuss) {
var msg;
msg = adsstatuss;
alert(msg.length);
var updated_status = msg[0].post_status;
alert(updated_status);
//alert(updated_status);
if (updated_status == "0" && tdid == prod_id) {
td.css("background", "#ccffcc");
td.text("On");
thiss.val(updated_status);
}
if (updated_status == "1" && tdid == prod_id) {
td.css("background", "#ffcccc");
td.text("Off");
thiss.val(updated_status);
}
});
}
});
ads_status (method in CodeIgniter)
public function ads_status() {
$prod_id = $_POST['prod_id'];
$status = $_POST['status'];
if ($status == "1") {
$new_status = "0";
$this->cmsdbmodel->ads_status($prod_id, $new_status);
$dat = $this->cmsdbmodel->get_updated_status($prod_id);
$ads_type = "product";
$emailreturn = $this->send_email_ads_status($prod_id, $ads_type);
//send user alert of product//
if ($dat[0]->post_status == "0") {
$lastInsertedId = $prod_id;
$modelNBrandId = $this->dbmodel->checkProductContainsAlert($lastInsertedId);
$getAlertEmail = $this->dbmodel->getAlertEmailFromBrandNModelId($modelNBrandId);
if (!empty($getAlertEmail)) {
foreach ($getAlertEmail as $alerts) {
$alertsEmail = $alerts->email;
}
}
$alertsPost = $this->dbmodel->getPostAlerts($lastInsertedId);
$sendPostAlerts = json_encode($alertsPost);
$encrytpEmail = hash('sha256', $alertsEmail);
$this->pusher->trigger($encrytpEmail, 'alerts', $sendPostAlerts);
}
//send user alert of product//
$realtime = $this->realTime_charts();
$realtime["post_status"] = $dat[0]->post_status;
$realtime["emailres"] = $emailreturn;
$data = $realtime;
$this->pusher->trigger('recent_activity', 'new_event1', $data);
echo json_encode($data);
}
}
Here I want to trigger event in pusher as well as echo json object. But in ajax, response is undefined. Also in console I can see json but when alerting the reponse it says undefined. Wheres problem in my code. Please help me.

How get AJAX to Post JSON data into div

I'm new Jquery and AJAX and I've really been struggling with the syntax I've been trying to use other tutorials as reference but nothing seems to work. I feel I have the right idea but syntax is wrong somewhere please help.
Here is the Ajax side
var var_numdatacheck = <?php echo $datacheck; ?>;
var var_numcheck = parseInt(var_numdatacheck);
function activitycheck(){
$.ajax({
type: 'POST',
url: 'feedupdate.php',
data: {function: '3test', datacheck: var_numcheck},
dataType: "json",
success: function(data) {
var json = eval('(' + data + ')');
$('#datacheck').html(json['0']);
var var_numcheck = parseInt(msg);
//setTimeout('activitycheck()',1000)},
error:function(msg) {
console.log(msg);
}
});
}
$(document).ready(function() {
activitycheck();
});
Here is the php the AJAX calls
<?php
require "dbc.php";
$function = $_POST['function'];
$datacheck = $_POST['datacheck'];
$search="SELECT * FROM Feedtest ORDER BY id DESC";
$request = mysql_query($search);
$update= mysql_fetch_array($request);
$updateid = $update['id'];
$updatecheck = mysql_num_rows($request);
$data = array();
if ($function == $datacheck){
echo $updatecheck;
echo $datacheck;
}
if ($function == "3test" && $updatecheck > $datacheck ) {
$updatesearch="SELECT * FROM Feedtest WHERE id = '$updateid' ORDER BY id DESC";
$updatequery = mysql_query($updatesearch);
$data['id'] = $updateid;
while ($row = mysql_fetch_array($updatequery))
{
?>
<?php $data[]= $row['First Name']; ?>
<?php
}
echo json_encode($data);
}
?>
</div>
</ul>
first of all ,always use JSON.parse(data) instead of eval.It is considereda a good practice.
second thing is always try to debug your code by checking it in console or alerting.In your context,this is what is happening-:
$.ajax({
type: 'POST',
url: 'feedupdate.php',
data: {function: '3test', datacheck: var_numcheck},
dataType: "json",
success: function(data) {
var data = eval('(' + data + ')');
console.log("myData"+data)//debugging.check the pattern so that you can acces it the way you want!!!
for(var i=0;i< data.length;i++)
{
alldata += "<li>"+data[i][0]+"<li><hr>";
}
$('#datacheck').html(alldata);
});
}
For JSON.parse:
success: function(data) {
var data = JSON.parse(data);
console.log("myData"+data)//debugging.check the pattern so that you can acces it the way you want!!!
for(var i in data)
{
alldata += "<li>"+data[i].First Name+"<li><hr>";
}
$('#datacheck').html(alldata);
});
