How to pass parameters with php in my case

Question

I am getting an "Uncaught SyntaxError: Unexpected token ILLEGAL" error when try to load a page with a php variable.

$(document).ready(function() {
       $.get("index.html", {token:<?php echo $token; ?>}, function(data) {
                 //codes..
               });
 });

I can't seem to echo $token in my javascript and I am sure $token is valid.

Can someone help me solve this issue? Thanks a lot!

Is token a string? {token:'<?php echo $token; ?>'}

You're echoing text from PHP into a Javascript context, which means you have to generate valid Javascript code. Simplest solution: json_encode()

{token : <?php echo json_encode($token) ?>}

json_encode() will take care of any quoting/escaping which needs to be done.

e.g. if $token = 'foo', then you'd be producing

{token: foo}

and be producing an undefined variable error.

you need to put quotes around the php output otherwise it will be treated as a javascript variable rather than a string

{token:'<?php echo $token; ?>'}
