Ajax passing data to php script - php

I am trying to send data to my PHP script to handle some stuff and generate some items.
$.ajax({
type: "POST",
url: "test.php",
data: "album="+ this.title,
success: function(response) {
content.html(response);
}
});
In my PHP file I try to retrieve the album name. Though when I validate it, I created an alert to show what the albumname is I get nothing, I try to get the album name by $albumname = $_GET['album'];
Though it will say undefined :/

You are sending a POST AJAX request so use $albumname = $_POST['album']; on your server to fetch the value. Also I would recommend you writing the request like this in order to ensure proper encoding:
$.ajax({
type: 'POST',
url: 'test.php',
data: { album: this.title },
success: function(response) {
content.html(response);
}
});
or in its shorter form:
$.post('test.php', { album: this.title }, function() {
content.html(response);
});
and if you wanted to use a GET request:
$.ajax({
type: 'GET',
url: 'test.php',
data: { album: this.title },
success: function(response) {
content.html(response);
}
});
or in its shorter form:
$.get('test.php', { album: this.title }, function() {
content.html(response);
});
and now on your server you wil be able to use $albumname = $_GET['album'];. Be careful though with AJAX GET requests as they might be cached by some browsers. To avoid caching them you could set the cache: false setting.

Try sending the data like this:
var data = {};
data.album = this.title;
Then you can access it like
$_POST['album']
Notice not a 'GET'

You can also use bellow code for pass data using ajax.
var dataString = "album" + title;
$.ajax({
type: 'POST',
url: 'test.php',
data: dataString,
success: function(response) {
content.html(response);
}
});

$.ajax({
type: 'POST',
url: 'test.php',
data: { album: this.title },
success: function(response) {
content.html(response);
}
});

php jquery dynamic dropdown

I am having problem sending/reading ajax variable.
Ajax code is as below:
$.ajax({
url: "/wp-content/themes/canvas-child/get-clients-dropdown.php?it=1",
success: function(data) {
$("#ClientID").html(data);
}
});
I have tried to read it in another php file like this:
$InvoiceType = $_REQUEST['it'];
//$InvoiceType = $_POST['it'];
//$InvoiceType = $_GET['it'];
But none of above works. The variable $InvoiceType always stays empty.
What is the problem?
The best way is to use POST method like this :
$.ajax({
method: "POST",
url: ""/wp-content/themes/canvas-child/get-clients-dropdown.php",
data: { it: 1, param2: "value2" }
})
You can get your value in $_POST['it']
Please try it with full url of file with get_template_directory_uri().
$.ajax({
type: 'GET',
url: '<?php echo get_template_directory_uri(); ?>/get-clients-dropdown.php',
data: {it: 1},
success: function(data) {
$("#ClientID").html(data);
}
});
$.ajax({
type: "GET",
data: {it: "1"},
url: "/wp-content/themes/canvas-child/get-clients-dropdown.php?it=1",
success: function(data) {
$("#ClientID").html(data);
}
});
try this
You have to use it like this:
$.ajax({
type: "POST",
url: "/wp-content/themes/canvas-child/get-clients-dropdown.php?it=1",
success: function(data) {
$("#ClientID").html(data);
}
});
Then in PHP File use this:
$InvoiceType = $_POST['it'];

How to Send Jquery Ajax data on Same php Page?

hi i want to send javascript data via ajax to the same page in wordpress. Cannot fetch the data in testajax.php page. its shows Undefined index: name. And how to send the data on same php page rather than testajax.php ?
<script>
jQuery.ajax({
type: "POST",
url: 'http://localhost/projects/xxx/wordpress/wp-content/themes/xxx/testajax.php',
data: {name:'foo'},
success: function(data)

type: "POST",
data: {name:'foo'},

ajax link json datatype call

I want to send the data via ajax to other page. I have isolated the problem. This is the code.
Thank you all for your help..But no effect..
updated code
It worked...
<script>
$(document).ready(function(){
$(".edit").click(function(event) {
event.preventDefault(); //<--- to prevent the default behaviour
var box = 1233;
var size=123;
var itemname=123;
var potency=123;
var quantity=12333;
var dataString ={
'box' :box,
'size':size ,
'itemname':itemname,
'potency':potency,
'quantity':quantity
};
$.ajax({
url: "dd.php",
type: "post",
data: dataString,
success: function(data) {
alert(data);
},
error: function(data) {
alert(data);
}
});
});
});
</script>
So I click the link,it navigates, to dd.php which has
<?php
echo json_encode(array('itemcode'=>$_POST['itemname']));
echo $_POST['itemname'];
?>
I get Object Object as alert. What am doing wrong? Pls throw some light here..thanks you..
$(document).ready(function(){
$(".edit").click(function(event) {
event.preventDefault();
var data = {"box":1233,
"size":565,
"itemname":565,
"potency":876,
"quantity":234};
$.ajax({
url: "dd.php",
type: "post",
data: data,
dataType: "json",
success: function(data) {
if(console){
console.log(data);
}
},
error: function(data) {
if(console){
console.log(data);
}
}
});
});
});
few things to consider... you can post data as object..which is clean and easier to use
$(".edit").click(function(event) {
event.preventDefault(); //<--- to prevent the default behaviour
var box = 1233;
....
var dataString ={'box':box,'size':size,'itemname':itemname,'potency':potency,'quantity':quantity};
$.ajax({
url: "dd.php",
type: "post",
data: dataString,
dataType: "json", //<--- here this means the response is expected as JSON from the server
success: function(data) {
alert(data.itemcode); //<--here alert itemcode
},
error: function(data) {
alert(data);
}
});
so you need to send the response as json in PHP
<?php
echo json_encode(array('itemcode'=>$_POST['itemname']))
?>
Here you are using querystring as sent in GET request.
If you want to send the data in same form, you can use this with GET request type:
$.ajax({
url: "dd.php"+dataString,
type: "get",
dataType: "json",
success: function(data) {
console.log(data);
alert(data.itemcode);
},
error: function(data) {
alert(data);
}
});
Or for POST request,you will have to put data in json object form, So you can use :
var dataString ={
'box' :box,
'size':size ,
'itemname':itemname,
'potency':potency,
'quantity':quantity
};
$.ajax({
url: "dd.php",
type: "post",
data: dataString,
dataType: "json",
success: function(data) {
console.log(data);
alert(data.itemcode);
},
error: function(data) {
alert(data);
}
});
});
And put echo in your php code :
<?php
echo json_encode(array('itemcode'=>$_POST['itemname']))
?>
Javascript alert shows [Object object] for object. You can see response using console.log or can use that key with alert.

sending data through ajax to CI controller

I am new to ajax and CI .I want to send data and image through ajax . In my view i have 3 input fields and one image upload button .
var val1 = $("#val1"+id).val();
var val2 = $("#val2").val();
$.ajax({
type: "POST",
url: "page/save_data",
data: "{ val1 :'"+val1+"',val2:'"+val2+"}",
success: function(msg) {
alert(msg);
}
});
and in controller when i try this it shows me nothing
function save_data()
{
$val = $this->input->post('val1');
echo $val1;
}
In console it gives me nothing .
Try this :
$.ajax({
type: "POST",
url: "page/save_data",
data: { "val1 ":val1,"val2": val2},
success: function(msg) {
alert(msg);
}
});
Your ajax URL must be refer to your method name;
...
$.ajax({
type: "POST",
url: "page/save_data", //change this to your method;
...
should be like:
...
$.ajax({
type: "POST",
url: "page/save_iudata",//or whatever your method's name;
...
EDIT:
try this way:
function save_data(){
$val1 = $_REQUEST['val1'];
echo $val1;
}
Hello to send data via ajax is easy:
var data = {
val1: $('#val1').val(),
val2: $('#val2').val(),
};
$.ajax({
url: "<?php echo base_url().'page/save_data'; ?>",
dataType: 'json',
type: 'POST',
async : false,
data: data,
success: function(msg){
...
}
});
return false;
But to send an image you have to do some research...
here is a good tutorial

read JSON data from PHP with jQuery

I send an array from PHP with json_encode, and I trying to get with AJAX and jQuery.
Every thing is ok.
JSON structure is :
names{"p1":"John","p5":"Smith"}
jQuery code is :
$.ajax({
type: "POST",
url: "return.php",
dataType: "json",
data: "id=56",
success: function(data) {
$(data.names).each(function(key, txt) {
alert(txt);
});
}
}
this code don't return any thing! I think browser don't enter in each
what should I do ?
instead this:
$(data.names).each(function(key, txt) {
alert(txt);
});
use this:
$.each(data.names, function(key, txt) {
alert(txt);
});
and your json seems to be incorrect as you mentioned: names{"p1":"John","p5":"Smith"}
this should be like this:
{
"names": {
"p1": "John",
"p5": "Smith"
}
}
you can check your json here: http://jsonlint.com/
I'd suggest you use jQuery's $.getJSON(); http://api.jquery.com/jQuery.getJSON/
But to answer your question directly; you didn't close your ajax() function.
$.ajax({
type: "POST",
url: "return.php",
dataType: "json",
data: "id=56",
success: function(data) {
$(data.names).each(function(key, txt) {
alert(txt);
});
}
});
In your code you could just use parseJSON().
$.ajax({
type: "POST",
url: "return.php",
dataType: "json",
data: "id=56",
success: function(data) {
var d = jQuery.parseJSON(data);
// ... do stuff
}
});
