Hi,
It's probably a bit late but I found a solution for this... basically I wanted to display wpdiscuz comments for photo posts in popups. My functionality exists in a plugin itself. Here's how I did it.
1. wpdiscuz uses the global $post->ID by default for comment functionality. This means the page id rather than photo id is being used when a comment within a photo popup is posted. So... firstly I needed to find a way to pass the photo id to the wpdiscuz plugin.
2. To do this I looked in wpdiscuz plugins directory > class.WpdiscuzCore.php. A wpdiscuz-ajax-js script is enqueued here and then the variable wpdiscuzAjaxObj is localised. This variable contains an object with the post_id as a property to be used for ajax operations. I specifically needed to update this variable on a click event of each call-to-action child within a comment wrapper element (I wrapped a <div> around each photo's comments area). On the comment wrapper I specified a data-pid attribute containing the photo id. Now the event handler on the child element can reference this when clicked, eg.
$(document).on('click', '.wpdiscuz-sort-button, input.wpd_label__checkbox, .wc_comm_submit, .wc-vote-link, .wc-cta-button', function(e) {
wpdiscuzAjaxObj.wpdiscuz_options.wc_post_id = $(this).closest('.comment-wrap').data('pid');
});
3. The enqueued wpdiscux-ajaz-js script (wpdiscuz.js) sets a local variable in an encapsulated jquery function to point to the value of the localised wpdiscuzAjaxObj variable (that I set on click), i.e.
var wpdiscuzPostId = wpdiscuzAjaxObj.wpdiscuz_options.wc_post_id;
This variable is out of reach from my script so I took a copy of this file in my plugin and customised it by commenting out the above assignment and replacing any usages of wpdiscuzPostId with the global variable wpdiscuzAjaxObj.wpdiscuz_options.wc_post_id.
4. To use this file I dequeued the original, wpdiscux-ajaz-js in my plugin and enqueue my amended version, custom-wpdiscuz-ajax-js.
5. With this newly queued file I needed to localize the existing variable, wpdiscuzAjaxObj against it... to do this, I grabbed the value of the original variable, which is returned as a string, converted it to an array and localised it against my custom custom-wpdiscuz-ajax-js script, eg.
global $wp_scripts;
$wpdiscuzOptionsJs = $wp_scripts->get_data('wpdiscuz-ajax-js', 'data');
if ( !is_array($wpdiscuzOptionsJs) ) {
$wpdiscuzOptionsJs = json_decode(str_replace('var wpdiscuzAjaxObj = ', '', substr($wpdiscuzOptionsJs, 0, -1)), true);
}
if ( is_page('xxx') ) {
// Slight modified copy of wpdiscuz needed for this page to accept passed in/popup post ids, rather than using the default post id.
wp_dequeue_script( 'wpdiscuz-ajax-js' );
wp_enqueue_script( 'custom-wpdiscuz-ajax-js', PHOTO_PLUGIN_URL . 'stream/js/wpdiscuz.js', array('jquery'), 'custom.5.3.5', true );
wp_localize_script('custom-wpdiscuz-ajax-js', 'wpdiscuzAjaxObj', array('url' => admin_url('admin-ajax.php'), 'customAjaxUrl' => plugins_url() . '/wpdiscuz/utils/ajax/wpdiscuz-ajax.php', 'wpdiscuz_options' => $wpdiscuzOptionsJs));
}
That's it! So now with every comment call-to-action the global variable is updated with the photo id and used directly by the custom wpdiscuz.js file. I hope this makes sense.
