使用AJAX将参数发送到php控制器的最佳方法

I want to sent 2 parameters from the client ( jquery ) side to server side ( php-codeigniter ). The parameters are id ( an integer ) and text ( a string ). I tried:

window.location.href="AjaxUpdate/sendMessage/"+id+"/"+text;

which has worked for me in the past using only the id, but because the text string can have spaces I can get:

http://localhost/b1/mycontroller/myfunction/3/gdfgdgd%20&nbsp;%20&nbsp;gd

which gives:

An Error Was Encountered
The URI you submitted has disallowed characters.

What is the best way to prepare and transmit a string to the server side using jquery? I assume ajax will be used in some way

You can use the jQuery .ajax() function to POST data (JSON) to your PHP script, like this:

var postData = {
    "param1" : some_value1,
    "param2" : some_value2
};

console.log(postData);

$.ajax({
    type: "POST",
    url: "test.php",
    data: postData, 
    success: function(){
        alert(param1 + ' ' + param2);
        window.open("test.php"); 
    }
});

UPDATE:

PHP sample that I Googled and found; it doesn't seem to do much, but unfortunately I am not versed in PHP at all:

//request parameters
$param_1 = $_POST['param1'];
$param_2 = $_POST['param2'];

echo 'postData: ' . var_dump($_POST);

if ($_POST)){
    echo $param_1;
    echo $param_2;
} else {
    echo 'problem';
}
