pull in video URL for custom slide markup
Look at that. I'm learning php (sorta). I figured it out. For anyone else trying to solve something similar:
/* this code will work if you just add it to your functions.php */
// Create PHP class that will hold methods
class MyRoyalSliderRendererHelper {
private $post;
private $options;
function __construct( $data, $options ) {
// $data variable holds WordPress post object only for Posts Slider
// for other types sliders it holds just data associated with slide, print it to see what's inside
$this->post = $data;
// slider options (that you choose in right sidebar)
$this->options = $options;
}
function hello_world() {
return "Hello World!";
}
function post_id() {
return $this->post->ID;
}
function my_video_url() {
$videonum = $this->post->ID;
return get_the_post_video_url( $videonum );
}
}
/**
* @param [object] $m Mustache_Engine object
* @param [object] $data Object with slide data (for example for posts slider it's WordPress Post Object)
* @param [object] $options Array of RoyalSlider options
*/
function newrs_add_custom_variables($m, $data, $options) {
// initialize helper class
$helper = new MyRoyalSliderRendererHelper($data, $options);
// add {{hello_world}} variable that gets data from hello_world function of MyRoyalSliderRendererHelper class
$m->addHelper('hello_world', array($helper, 'hello_world') );
// same, but for post_id
$m->addHelper('post_id', array($helper, 'post_id') );
// my_video_url
$m->addHelper('my_video_url', array($helper, 'my_video_url') );
}
add_filter('new_rs_slides_renderer_helper', 'newrs_add_custom_variables', 10, 4);
