i am passing my variable throught an AJAX request in javascript but not getting it in my php file. NOt sure where i am going wrong.?
JS code
var build = {
m_count : (document.getElementById('count').value),
}
$.ajax({
data: build,
type: "POST",
url: "tabs.php",});
PHP code
<?php
$module_c = $_POST['data'];
echo $module_c;
?>
You have to get the data by the name of the variable you want to get, which is m_count.
<?php
$module_c = $_POST['m_count'];
echo $module_c;
?>
EDIT:
Like suggested in the comments, change your JavaScript code to:
var build = {
m_count : (document.getElementById('count').value)
}
$.ajax({
data: build,
type: "POST",
url: "tabs.php",
success: function(data) {
alert(data);
}
});
PHP:
<?php
$module_c = $_POST['m_count'];
echo $module_c;
?>
JS:
var build = {
m_count : (document.getElementById('count').value),
}
$.ajax({
url: 'php/server.php',
type: 'POST',
data: build,
})
.done(function(msg) {
// JSON.parse turns a string of JSON text into a Javascript object.
var message = JSON.parse(msg);
alert(message);
}
})
.fail(function(err) {
console.log("Error: "+err);
})
.always(function() {
console.log("Complete");
})
;

I have been trying to work this out for hours now and cannot find any answer that helps me.
This is the code in my javascript file
function sendMovement(cel) {
var name = "test";
$.ajax({
type: 'POST',
url: '../game.php',
data: { 'Name': name },
success: function(response) {
console.log("sent");
}
});
}
This is the code from my PHP file (it is outside the js file)
if($_SERVER["REQUEST_METHOD"] == "POST") {
$data = $_POST['Name'];
console_log($data);
}
When debugging I can see that AJAX is sending a POST and it does print in the console "SENT" but it does not print $data
update: the function console_log() exists in my PHP file and it works
Try getting response in JSON format, for that your js should have dataType:'JSON' as shown below
JS Code:-
function sendMovement(cel) {
var name = "test";
$.ajax({
type: 'POST',
dataType:'JSON', //added this it to expect data response in JSON format
url: '../game.php',
data: { 'Name': name },
success: function(response) {
//logging the name from response
console.log(response.Name);
}
});
}
and in the current server side code you are not echoing or returning anything, so nothing would display in ajax response anyways.
changes in php server code:-
if($_SERVER["REQUEST_METHOD"] == "POST") {
$response = array();
$response['Name'] = $_POST['Name'];
//sending the response in JSON format
echo json_encode($response);
}
I fixed it by doing the following:
To my game.php I added the following HTML code (for debugging purposes)
<p style = "color: white;" id="response"></p>
Also added in my game.php the following
if($_SERVER["REQUEST_METHOD"] == "POST") {
$gameID = $_POST['gameID'];
$coord = $_POST['coord'];
$player = $_POST['player'];
echo "gameID: " . $gameID . "\nCoord: " . $coord . "\nPlayer: " . $player;
}
AND in my custom.js I updated
function sendMovement(cel) {
var handle = document.getElementById('response');
var info = [gameID, cel.id, current_player];
$.ajax({
type: 'POST',
url: '../game.php',
data: {
gameID: info[0],
coord: info[1],
player: info[2]
},
success: function(data) {
handle.innerHTML = data;
},
error: function (jqXHR) {
handle.innerText = 'Error: ' + jqXHR.status;
}
});
}
I am working on a chat system which refreshes automatically using AJAX. First I was using the jQuery $.post function, but since i wanted to return JSON data from my PHP script, i want to use the $.ajax function. My script worked well using the $.post function, but i can not return JSON. This is the relevant code:
Javascript:
$.ajax({
url: "pages/loadmessage.php",
type: "POST",
data: {"c": getUrlParameter("c"), "t": messagetime},
dataType: "json",
success: function(pData){
console.log(pData);
},
error: function(xhr, status, error) {
alert(error + status);
}
});
PHP Code:
<?php
require_once("../init.php");
header('Content-Type: application/json');
if (Input::exists() && Input::get("c") && Input::get("t")) {
$chat = new Chat($user->data()->ID, Input::get("c"));
$messages = $chat->getNewMessages(Input::get("t"), $user->data()->ID);
if ($messages) {
$result = array(
'topic' => $chat->getTopic(),
'messages' => array()
);
foreach($messages as $m) {
array_push($result['messages'], array('source' => 'mine', 'Text' => $m->Text));
}
echo json_encode("string!!!");
}
} else {
echo json_encode("string" . Input::get("c") . Input::get("t") . Input::exists());
}
?>
I already tried to set the contentType of the AJAX call to "application/json" and convert the data to JSON using JSON.stringify, but then no input data gets to the PHP script. The code works if just one parameter (data: {"c": getUrlParameter("c")}) is sent to the PHP script...
I already searched StackOverflow, but i could not find a solution...
Thanks
JSON example:
Index.html
<script type="text/javascript">
$.ajax({
url: "out.php",
type: "POST",
data: {"param1": "test 1", "param2": "test2"},
dataType: "json",
success: function(data){
alert("param1:"+data.param1+" | param2:"+data.param2);
},
error: function(xhr, status, error) {
alert(error + status);
}
});
</script>
out.php
<?php
if(isset($_POST["param1"])){ $param1 = $_POST["param1"];}
if(isset($_POST["param2"])){ $param2 = $_POST["param2"];}
$out = array("param1"=>$param1,"param2"=>$param2);
echo(json_encode($out));
?>
AJAX:
$(document).ready(function () {
$('.my_button').click(function () {
var data = $(this).val();
//alert(BASE_URL);
$.ajax({
type: "POST",
ContentType: 'application/json',
data: data,
url: BASE_URL + 'index.php?deo/dashboard',
error: function () {
alert("An error occoured!");
},
success: function (msg) {
alert('result from controller');
}
});
alert(data);
});
});
CONTROLLER:
public function dashboard() {
$data = $this->input->post('data');
$data = json_decode($data);
echo "<script>alert('count ".$data."');</script>";
}
Am trying to send value from my jquery, ajax to controller, am able to get value from my view page to jquery page and able to print that. But unable to send the value from ajax page to controller page, after sending the data i got the success data. but unable to get and print the data in my controller page. Thanks in advance
If your using firefox a good thing to use is firebug add on and then you can use the console to check for errors on there. To see if the ajax has any errors while sending.
Remove question mark after index.php? and I think your base url is not working correct try just.
Url
// With index.php
url: 'index.php/deo/dashboard',
// Or without index.php
url: 'deo/dashboard',
Or
// With index.php
url: <?php echo site_url('index.php/deo/dashboard');?>,
// Or without index.php
url: <?php echo site_url('deo/dashboard');?>,
Script
$(document).ready(function () {
$('.my_button').click(function () {
var data = $(this).val();
$.ajax({
type: "POST",
data: data,
url: 'index.php/deo/dashboard',
// url: <?php echo site_url('index.php/deo/dashboard');?>,
success: function (msg) {
alert('result from controller');
},
error: function () {
alert("An error occoured!");
}
});
alert(data);
});
});
Controller
public function dashboard() {
$data = $this->input->post('data');
echo "<script>alert('count ".$data."');</script>";
}
I'm trying to send a associative array via AJAX $.post to php. Here's my code:
var request = {
action: "add",
requestor: req_id,
...
}
var reqDetails = $("#request_details").val();
switch(reqDetails){
case 1:
request[note] = $("#note").val();
break;
...
}
if(oldRequest()){
request[previousID] = $("old_id").val();
}
$('#req_button').toggleClass('active');
$.post("scripts/add_request.php", {
request_arr: JSON.stringify(request)
}, function(data){
console.log(data);
$('#req_button').toggleClass('active');
}, 'json');
And i'm simply trying to read the received data in my php script:
echo json_decode($_POST["request_arr"]);
But it's not working. I'm a newbie to js, I can't figure out what I'm doing wrong.
Check below link for your reference
Sending an array to php from JavaScript/jQuery
Step 1
$.ajax({
type: "POST",
url: "parse_array.php",
data:{ array : JSON.stringify(array) },
dataType: "json",
success: function(data) {
alert(data.reply);
}
});
Step 2
You php file looks like this:
<?php
$array = json_decode($_POST['array']);
print_r($array); //for debugging purposes only
$response = array();
if(isset($array[$blah]))
$response['reply']="Success";
else
$response['reply']="Failure";
echo json_encode($response);
Step 3
The success function
success: function(data) {
console.log(data.reply);
alert(data.reply);
}
You are already using "json" as dataType, so you shouldn't apply 'stringify' operation on your data.
Instead of request_arr: JSON.stringify(request), can you try request_arr: request directly?
I am trying to write a script that will add the video currently being viewed to a database of favourites. However every time it runs, an error is returned, and nothing is stored in the database.
Here is the JQuery
$(document).ready(function() {
$("#addfav").click(function() {
var form_data = {heading: $("#vidheading").text(), embed : $("#vidembed").text()};
jQuery.ajax({
type:"POST",
url:"localhost/stumble/site/add_to_fav.php",
dataType: "json",
data: form_data,
success: function (data){
console.log(data.status);
alert("This Video Has Been Added To Your Favourites")
},
error: function (data){
console.log(data.status);
alert("You Must Be Logged In to Do That")
}
});
})
})
The add_to_fav.php is this...
public function add_to_fav(){
$this->load->model('model_users');
$this->model_users->add_favs();
}
And the add_favs function is below
public function add_favs(){
if($this->session->userdata('username')){
$data = array(
'username' => $this->session->userdata('username'),
'title' => $this->input->post('heading'),
'embed' => $this->input->post('embed')
);
$query = $this->db->insert('fav_videos',$data);
if($query){
$response_array['status'] = 'success';
echo json_encode($response_array);
}}else {
$response_array['status'] = 'error';
echo json_encode($response_array);
}
}
Thank you for the input, this has me stuck but I am aware it may be something relatively simple, my hunch is that it is something to do with returning success or error.
Try
$(document).ready(function() {
$("#addfav").click(function() {
var form_data = {heading: $("#vidheading").text(), embed : $("#vidembed").text()};
jQuery.ajax({
type:"POST",
url:"http://localhost/stumble/Site/add_to_fav",
dataType: "json",
data: form_data,
success: function (data){
console.log(data.status);
alert("This Video Has Been Added To Your Favourites")
},
error: function (data){
console.log(data.status);
alert("You Must Be Logged In to Do That")
}
});
})
})
Also to use base_url in javascript. In your template view :-
<script>
window.base_url = "<?php echo base_url(); ?>";
</script>
Now you can use base_url in all your ajax scripts.
