Passing boolean values with wp_localize_script

by

I am using wp_localize_script to pass a couple of values from my theme options to a javascript file. First I got the values from my theme options:

$options = get_option('theme');  
$flex_auto = $options["slide-auto"];
$flex_animation = $options["slide-animation"];
$flex_direction = $options["slide-direction"];

Then I used wp_localize_script to create my array of values.

wp_enqueue_script('flexslider');
wp_localize_script('flexslider', 'flex_vars', array(
    'flex_auto' => $flex_auto,
    'flex_animation' => $flex_animation,
        'flex_direction' => $flex_direction
    )
);

In my javascript file I did this: 

var $anim = flex_vars.flex_animation;
var $auto = flex_vars.flex_auto;
var $dire = flex_vars.flex_direction;

jQuery('.flexslider').flexslider({
    animation: $anim,
    slideshow: $auto,
    controlNav: 'thumbnails',
    directionNav: $dire, 
    slideshowSpeed: 7000,
    animationSpeed: 1000,
    touch: true,
});

My theme options include some values that are made with checkboxes which work with 0/1 booleans while the jQuery plugin I’m using works with true/false. I tried saving the boolean value as strings by using a drop-down menu with two options, either true or false, but that doesn’t seem to work. How can I pass the boolean values from the theme options to the javascript file? Any suggestions and hints very welcome 🙂

Try this:

$options = get_option( 'theme' );

wp_localize_script( 'flexslider', 'flex_vars', array (
  'flex_auto' => ($options['slide-auto']) ? 'true' : 'false',
  'flex_animation' => $options['slide-animation'],
  'flex_direction' => $options['slide-direction']
) );

Assuming slide-auto is the option you made a boolean.

This script isn’t tested, I directly typed it in here.
