jQuery Ajax posting not working - php

My jQuery ajax posting is not working. Here is the javascript
function SocialButtons() {
var $buttonWrapper = jQuery('.WrapperDiv');
if ($buttonWrapper.length){
var postData = $buttonWrapper.html();
jQuery.ajax({
type: 'POST',
url: 'http://www.wordpress-site.com/wp-contents/themes/theme-name/post.php',
data: postData,
cache: false,
success: function(data) {
console.log(data);
},
contentType: "application/json",
dataType: 'json'
});
}
}
I am saving the data to be posted inside a hidden div like
<div class='WrapperDiv hidden'>{"post_id":392,"url":"http:\/\/www.wordpress-site\/post\/post-title\/","title":"SEO Friendly title"}</div>
All I am getting in return from the post.php page is an empty array. Here is my code for post.php
<?php
if(isset($_POST)){
print_r($_POST);
} else {
echo "0";
}
?>
Any Idea whats wrong?
EDIT : Its working after I removed
contentType: "application/json",
dataType: 'json'

What about something like this:
var postData = "data=" + encodeURCIComponent($buttonWrapper.html());
Than in PHP:
echo $_POST["data"];
Than parse it or something....

Couple of things to try,
Try to pass the data directly in to the data object first. If it
works then you can debug and see why it's not ready your hidden div.
instead of $buttonWrapper.html try $buttonWrapper.text();
function SocialButtons() {
var $buttonWrapper = jQuery('.WrapperDiv');
if ($buttonWrapper.length){
var postData = $buttonWrapper.**text**();
jQuery.ajax({
type: 'POST',
url: 'http://www.wordpress-site.com/wp-contents/themes/theme-name/post.php',
data: **{'id':1}**,
cache: false,
success: function(data) {
console.log(data);
},
contentType: "application/json",
dataType: 'json'
});
}
}

Inside your jQuery ajax call, your data is not set to $_POST variable names. Hence why nothing is showing
Try changing your function to this:
function SocialButtons() {
var buttonWrapper = jQuery('.WrapperDiv');
if (buttonWrapper.length){
var postData = buttonWrapper.html();
jQuery.ajax({
type: 'POST',
url: 'http://www.wordpress-site.com/wp-contents/themes/theme-name/post.php',
data: {postData: postData},
cache: false,
success: function(data) {
console.log(data);
},
contentType: "application/json",
dataType: 'json'
});
}
}
Then you should have a $_POST['postData'] variable on your print_r or var_dump of $_POST.

Its working after I removed
contentType: "application/json",
dataType: 'json'

Ajax Post and CodeIgniter not working

I am trying to echo back code I received from Ajax. But it does not work when I am using contentType:false, processData:false.
Here is my ajax. The url is correct. If I comment out the line with post_data['file'] and contentType:false, processData:false I will be able to get the echo, but as soon as contentType:false, processData:false is in I cannot get anything.
post_data = {};
post_data['file']= document.getElementById('fileToUpload').files[0];
post_data['paper-type']=$("#paper-input :selected").val();
$.ajax({
url:'/admin/upload_paper',
data: post_data,
type: 'post',
contentType: false,
processData: false,
success: function(data){
console.log(data);
},
error: function(data){
console.log(data+"error");
}
});
Here is the code snippet from CI
public function upload_paper(){
echo $this->input->post('paper-type');
echo "testing";
echo "testing2";
}
Does anyone know what that is? Thank you.
instead of doing this:
post_data['paper-type']=$("#paper-input :selected").val();
try
var val = $("#paper-input :selected").val();
and in ajax:
$.ajax({
url:'/admin/upload_paper',
data: {'paper-type':val},
type: 'post',
success: function(data){
console.log(data);
},
error: function(data){
console.log(data+"error");
}
});

AJAX send data to PHP file

send $username php with data: new FormData(this), to add.php like data: new FormData(this),$username how can i do it with ajax code
<script type="text/javascript">
$(document).ready(function (e) {
$("#uploadFormuserimg").on('submit',(function(e) {
e.preventDefault();
$.ajax({
url: "add.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$("#user_img_a").html(data);
},
error: function()
{ alert("error");
}
});
}));
});
</script>
var myData = new FormData(this);
myData.append('username','<?php echo $username; ?>');
and get on "add.php" like this
$username = $_POST['username'];
This worked on my side.
Based on comments to the question, specifically:
I just want to add some data
Are you just asking how to add more fields to the object that was created already in the data value? Something like this:
var myData = new FormData(this);
myData.append("anotherField", "anotherValue");
// etc.
Then just use that variable as your AJAX data:
$.ajax({
url: "add.php",
type: "POST",
data: myData,
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$("#user_img_a").html(data);
},
error: function()
{ alert("error");
}
});
You can store anything you like in a variable and use that variable at a later time. With a FormData object you would generally use .append() to add more key/value pairs to it.

Array object to php using ajax

How can i send data like this to php using ajax
["{"title":"mr","fname":"john","lname":"Annah","oname":"Clement","staffid":"123"}"]
try json_encode
for more refer -
http://php.net/manual/en/function.json-encode.php
Do it like so, using jQuery(which you need to include in your script):
<script>
var data={};
data= {
"title":"mr",
"fname":"john",
"lname":"Annah",
"oname":"Clement",
"staffid":"123"};
$.ajax({
url:"somwhere.php",
type:"POST",
dataType:"JSON",
data:data,
async: true});
</script>
And on the page where you want to catch this data, do it like this:
<?php
$title=$_POST['title'];
$fname=$_POST['fname'];
?>
And so on.
stringify before sending
Eg :
var postData = [
{ "id":"1", "name":"bob"},
{ "id":"2", "name":"jonas"}]
this works,
$.ajax({
url: Url,
type: 'POST',
contentType: 'application/json',
data: JSON.stringify(postData) //stringify is important,
});
Try this
$(document).on("click", "#your element", function () {
$.ajax({
type: 'POST',
url: "your_url",
data : {"title":"mr","fname":"john","lname":"Annah","oname":"Clement","staffid":"123"},,
success: function (result) {
### your action after ajax
},
})
})
you can pass it in data like this,
$.ajax({
url: 'url',
type: 'GET',
data: { title:"mr",fname:"john",lname:"Annah",oname:"Clement",staffid:"123" } ,
contentType: 'application/json; charset=utf-8',
success: function (response) {
//your success code
}
});

How to pass value to PHP Script

I have code in my html file as below. I am using jQuery Mobile
$.ajax({
type: "GET",
url: "http://localhost/owner_pickup.php",
cache: false,
dataType:'json'
success: function(data)
{
// On success
}
});
owner_pickup.php returns me data by executing query. Now i need to pass a value which i would read in my owner_pickup.php file.
Kindly suggest me how would we pass the value
in your php file:
$value = array(
"dat_1" => "this is data number 1",
"dat_2" => "this is data number 2"
);
echo json_encode($value);
in your jquery finction:
$.ajax({
type: "GET",
url: "http://localhost/owner_pickup.php",
cache: false,
dataType:'json'
success: function(data)
{
var value1 = data.dat_1;
var value2 = data.dat_2;
}
});
please look at this answers:
retrieve multiple values from ajax call
if you don't know how to use JSON please google it.
edit:
pass a value to the php:
$.ajax({
type: "GET",
url: "http://localhost/owner_pickup.php",
cache: false,
data: {
first_value:50,
second_value:55
}
dataType:'json'
success: function(data)
{
var value1 = data.dat_1;
var value2 = data.dat_2;
}
});
in the php:
if(isset($_GET['first_value']))
$first = $_GET['first_value'];
$.ajax({
type: "GET",
url: "http://localhost/owner_pickup.php",
data: {param1: 123, param2: "text value"},
cache: false,
dataType:'json',
success: function(data) { // On success }
});
$.ajax({
type: "GET",
url: "http://localhost/owner_pickup.php",
data:{key1:value1}
cache: false,
dataType:'json'
success: function(data)
{
}
});
In php aaccept it as
<?php
$_REQUEST['key1'];
?>

how to convert $.post form to $.ajax form?

I am noob at using jquery and ajax. I need to change the form from $.post to $.ajax .
var disqus_config = function() {
this.callbacks.onNewComment = [function(comment) {
$.post("sendnotification", { comment: comment.id, post: $post->id,author:$author->id}, function(result){
alert(result);
});
}];
};
I know I need to end something like here but I am stuck how to use post datas(comment,post,author) inside this function
$.ajax({
url: 'sendnotification',
type: 'POST',
data: 'query=' + query ,
dataType: 'JSON',
async: true,
success: function(data){
process(data)
}
Thanks
Just use the same object literal you did for $.post, eg (gotta assume that's some PHP or something in there)
$.ajax({
url: 'sendnotification',
type: 'POST',
data: { comment: comment.id, post: {$post->id}, author: {$author->id} },
dataType: 'json',
async: true,
success: function(data){
process(data)
}
});
I believe dataType: 'JSON' should be changed to dataType: 'json'
Also, use the same data array as you used in your $.post variant.
$.ajax({
url: 'sendnotification',
type: 'POST',
data: { comment: comment.id, post: $post->id,author:$author->id } ,
dataType: 'json',
async: true,
success: function(data){
process(data)
}
});
