Question

I am using PHP to save the values of a form as JSON into a cookie like so:

// set cookie with search values so we can use jQuery to repopulate the form
setcookie('jobSearchValues', json_encode($form_state['values']), 0, '/');

This works great and then on the JavaScript side I can use this to get at the values:

var jobSearchValues = JSON.parse($.cookie("jobSearchValues"));
$("#keywords").val(jobSearchValues.keywords);

Again this works great, but the problem is that when a value for one of the fields in the form has a space in it, the space gets replaced with a “+”. So when the form gets repopulated the text field displays like this for example “hi+mom”. Is there a better way to go about this? By the way, $form_state['values'] is a PHP array. There are 4 fields in the form that I am setting as JSON into the cookie.

Answer 1

Use setrawcookie( '<name>', rawurlencode( json_encode( $value ) ), ... ) and then manually url-decode & json-parse on the client side (with JSON.parse(decodeURIComponent(cookie)))
