Question

I have a script that posts data to a php script:

xhr.open("POST","processData.php");

And i am sending once piece of data to it:

xhr.send(email);

How would a post multiple peice of data to the php scrip? Lets say i have the variable first and last name that i want to sent to be processed? I’ve tried this:

xhr.send(essay, firstName);

But not sure what to do with it in the PHP script, do i use the usual $_POST[‘essay’] to collect the values? what about encoding aswell?

Thanks for you help.

Answer 1

You create an object, and send that:

var obj = {
    essay: essay,
    firstName: firstName
};
xhr.send("data=" + JSON.stringify(obj));

On server side you get:

json_decode($_POST['data']); //Gives you a standard object with fields essay and firstName
