I make jQuery Ajax request which return output in XML format.
i want to access this XML in PHP to Process on data.
Below is sample of my code...
getTime.php File
<?php
header("Content-type: text/xml");
echo '<Dates>';
echo '<Now ';
echo 'val="' . date("h:m:s") . '" ';
echo '/>';
echo '</Dates>';
//echo date("h:m:s");
?>
index.php File
jQuery(document).ready(function(e) {
$('#btnTime').click(function(){
getData("GetTime.php");
});
});
function getData(strUrl)
{
$.ajax({
type: "POST",
url: strUrl,
dataType: "xml",
success: function(output){
// I want to Retrieve this XML Object (output) to PHP
}
});
}
How can I access XML outputed by jQuery in PHP?
Please help me..
You need to make another call to your webserver in the success callback.
function getData(strUrl)
{
$.ajax({
type: "POST",
url: strUrl,
dataType: "xml",
success: function(output){
$.ajax({
type: "POST",
url: strUrlToPostXml,
dataType: "xml",
success: function(output){
// Whatever you want, the Xml has been successfully posted back to Php
}
});
}
});
}
But it's quite weird to do that though: it would be much better to have everything done on the server side using the initial call.

I am calling a PHP file from ajax but not getting any response from the PHP, I inspected there it showing No response available.
var str = "Hi";
$.ajax({
type: "POST",
url: "get_details.php",
data: str,
dataType: "json",
success: function(response) {
alert(response);
}
});
and my PHP file contains following.
<?php
echo "Hello";
?>
You should return JSON from get_details.php file, or change dataType attribute to html
function confirm_reg(id){
if(confirm("Are you sure want to complete")){
$('#'+id).hide(500);
$.post(
'sample.php',
{id6:id},
function(data){
alert(data);
}
);
}
}
sample.php
echo "something";
NO errors are showing in firebug console . even the hide function works . but posting is not working !
Try flollowing:
$.ajax({
type: "POST",
url: url,
data: data, //Data to be sent to server.
success: function(data) {
},
dataType: dataType //Type of data you are expecting from server such as xml, json, html, etc
});
I am working on my site and i have a jquery request to the server
$.ajax(
// do an ajax to send value to the database...
{
url:"pages/welcome_get.php",
type: "POST",
dataType: "json",
cache: false,
data: { wm_val: wel}
})
How can I get a response as a json data from which is not a html data and how do I parse the json response from the server to the html file?
You write the PHP to emit JSON.
<?php
# Some code to populate $some_associative_or_non_associative_array
header("Content-Type: application/json");
echo json_encode($some_associative_or_non_associative_array);
?>
You need to use the parseJSON function in the js.
Here is the Php code:
function send_reply(){
echo json_encode(array('reply'=>'here is my reply'));
exit;
}
Here is the js code:
$.ajax({
url:'myajax.php',
data:{'func':send_reply},
type:'POST',
dateType:'json'
}).success(function(data){
data=$.parseJSON(data);
alert(data.reply);
}).error(function(jqxhr,error,status){
alert('Error sending reply');
});
As #Quentin said, you need to output JSON in your PHP result. Then you need to use done() to receive the data on the client side and work with it from there:
$.ajax({
url:"pages/welcome_get.php",
type: "POST",
dataType: "json",
cache: false,
data: { wm_val: wel}
}).done(function( json ) {
// do something with json here
});
You need to add the "JSON" header to your "pages/welcome_get.php" file:
header("Content-Type: application/json");
And also in your AJAX call remember to add the "success" and "error" callback:
jQuery.ajax({
url:"pages/welcome_get.php",
type: "POST",
dataType: "json",
cache: false,
data: { wm_val: wel}
success: function(response) {
//Do stuff with response here
}
error: function(){
//Display error msg or something like that
}
});
lets say you are checking user in your welcome_get.php
then in your welcome_get.php
use this
if(isset($_GET['wm_val'])){
$wm_val = $mysqli->real_escape_string($_GET['wm_val']);
$check_user = $mysqli->prepare("SELECT email FROM members WHERE username = ? LIMIT 1 ");
$check_user->bind_param('s', $wm_val);
$check_user->execute();
$check_user->store_result();
$check_user->bind_result( $email);
$check_user->fetch() ;
if ($check_user->num_rows == 1) { $datas['msg']= "failed" ;}
else{$datas['msg']= "success" ;}
$check_user->close() ;
echo json_encode($datas);
}
and your ajax
$.ajax(
// do an ajax to send value to the database...
{
url:"pages/welcome_get.php",
type: "POST",
dataType: "json",
cache: false,
data: { wm_val: wel},
success: function(msg) {
if (data.msg == 'success'){
// do what you like here example
$('#mydata').html("<span >you welcome ! </span>").delay(4000).fadeOut('fast');
}else{
//do something else example
$('#mydata').html("<span >failed ! </span>").delay(4000).fadeOut('fast');
}
})
I know this has been asked before, but I can't get it working.
I'm loading a file on a page whose path and name are a variable contained in a PHP script.
My script.php is outputing a variable $filename which contains the path to a file that has to be open in an ajax request.
So, the file can be for example:
'../path/to/file/filea.json' or
'../another/path/fileb.json'
I tried this in my jQuery:
$.ajax({
url:'script.php',
success:$.ajax({
url: ??? // This ($filename) is what I'm trying to get from the 1st Ajax call
sucess: function(data){
//other code here
}
})
);
I know $filename is wrong in the second Ajax call but how do I get the value of that variable?
$.ajax({
url: "script.php",
success: function(data){
$.ajax({
var someParam=data; //response Data from 1st Ajax Call
type: "post",
url: "example.php",
data: 'page='+someParam,
success: function(data){
//Do More Here!
});
});
Try this:
inside script.php
echo json_encode($filename); //somewhere you need to have this echo.
jQuery
$.ajax({
url: 'script.php',
success: function (data) {
alert(data); //or console.log() and doublecheck you have the right info
$.ajax({
url: JSON.parse(data),
success : function (data) {
//other code here
}
})
}
}); // added a extra } to close the ajax
This solved the problem:
$.ajax({
async:false,
url: 'script.php',
success: function(data){
$.ajax({
url: data,
success: //code here
})
})
#Sergio: script.php wasn't echoeing the output of $filename... Thanks for reminding!
I want to pass values to a PHP script so i am using AJAX to pass those, and in the same function I am using another AJAX to retrieve those values.
The problem is that the second AJAX is not retrieving any value from the PHP file. Why is this? How can I store the variable passed on to the PHP script so that the second AJAX can retrieve it?
My code is as follows:
AJAX CODE:
$(document).ready(function() {
$("#raaagh").click(function(){
$.ajax({
url: 'ajax.php', //This is the current doc
type: "POST",
data: ({name: 145}),
success: function(data){
console.log(data);
}
});
$.ajax({
url:'ajax.php',
data:"",
dataType:'json',
success:function(data1){
var y1=data1;
console.log(data1);
}
});
});
});
PHP CODE:
<?php
$userAnswer = $_POST['name'];
echo json_encode($userAnswer);
?>
Use dataType:"json" for json data
$.ajax({
url: 'ajax.php', //This is the current doc
type: "POST",
dataType:'json', // add json datatype to get json
data: ({name: 145}),
success: function(data){
console.log(data);
}
});
Read Docs http://api.jquery.com/jQuery.ajax/
Also in PHP
<?php
$userAnswer = $_POST['name'];
$sql="SELECT * FROM <tablename> where color='".$userAnswer."'" ;
$result=mysql_query($sql);
$row=mysql_fetch_array($result);
// for first row only and suppose table having data
echo json_encode($row); // pass array in json_encode
?>
No need to use second ajax function, you can get it back on success inside a function, another issue here is you don't know when the first ajax call finished, then, even if you use SESSION you may not get it within second AJAX call.
SO, I recommend using one AJAX call and get the value with success.
example: in first ajax call
$.ajax({
url: 'ajax.php', //This is the current doc
type: "POST",
data: ({name: 145}),
success: function(data){
console.log(data);
alert(data);
//or if the data is JSON
var jdata = jQuery.parseJSON(data);
}
});
$(document).ready(function() {
$("#raaagh").click(function() {
$.ajax({
url: 'ajax.php', //This is the current doc
type: "POST",
data: ({name: 145}),
success: function(data) {
console.log(data);
$.ajax({
url:'ajax.php',
data: data,
dataType:'json',
success:function(data1) {
var y1=data1;
console.log(data1);
}
});
}
});
});
});
Use like this, first make a ajax call to get data, then your php function will return u the result which u wil get in data and pass that data to the new ajax call
In your PhP file there's going to be a variable called $_REQUEST and it contains an array with all the data send from Javascript to PhP using AJAX.
Try this: var_dump($_REQUEST); and check if you're receiving the values.
you have to pass values with the single quotes
$(document).ready(function() {
$("#raaagh").click(function(){
$.ajax({
url: 'ajax.php', //This is the current doc
type: "POST",
data: ({name: '145'}), //variables should be pass like this
success: function(data){
console.log(data);
}
});
$.ajax({
url:'ajax.php',
data:"",
dataType:'json',
success:function(data1){
var y1=data1;
console.log(data1);
}
});
});
});
try it it may work.......
