$.post() jQuery and PHP - php

Question

Here is a piece of code :
$username="anant";
$name="ana";
echo $username;
echo $name;
Now if using jquery $.post() i want to retrieve $username and $name ,how would I do it ?
Thanks!

Answer 1

I assume the code is your php based response to the $.post call. If all you are returning are values then the easiest thing to do is to return a json response. For example...
PHP Script:
$values = array(
'username' => 'anant'
'name' => 'ana'
);
header('Content-type: application/json');
echo json_encode($values);
JS $.ajax call:
$.ajax(
url: '/path/to/script.php',
type: 'post',
dataType: 'json',
success: function(data){
alert('Username: '+data.username);
alert('name: '+data.name);
}
);
Or if you wanna stick with $.post then follow kovshenin's answer for the syntax using $.post. But be sure you use my php code witht he header() call to properly set the content type of the http response. I just prefer to use the long hand.

I'm not a php expert but try something like:
php
$username="anant";
$name="ana";
echo json_encode(array("username"=>$username,"name"=>$name));
js
$(function() {
$.get('test.php', function(data) {
alert(data.username + ':' + data.name);
});
});
I hope this helps!

You will be better off with json_encode which javascript will understand just fine:
$res = array('username' => 'anant', 'name' => 'something');
echo json_encode($res);
Then use the following code in jQuery to retrieve the values:
$.post('/something', function(response) {
alert("Username is: " + response.username + " and name is: " + response.name);
}, "json");
Cheers.

Now that I know what you are trying to do post expects a fourth parameter the encoding type. If you set it to JSON you would encode your data like so
echo '{"username": ".'$username.'", name":"'.$name.'"}'; //Json may not be perfect
you can access it in jQuery using
data.username

Answer 5

First thing is you have to do a GET not a POST. You may need to change your server side code a little bit so that front end had a clue of how to identify different values (JSON will be better) but a simple , should work fine.
$username="anant";
$name="ana";
echo "$username,"
echo "$name";
your output will be then something like Anant001,Anant your username, name.
Then use a simple jQuery call to get it and split it by , and here is an example..
$.get('/getnames', function(data){
var tokens = data.split(",");
var username = tokens[0];
var name = tokens[1];
});
