Re use authenticated HTTP connection or cUrl handle

It is not possible, at least not within reason, to solve either of these issues due to fundamental limitations of PHP in a web envionment (mod_php).

How to get vim to autocomplete WordPress API functions?

It appears that the templates live in script form <script type=”text/html” id=”tmpl-my-custom-gallery-setting”> To render the above template would require wp.media.template(‘my-custom-gallery-setting’)(view) Since we’re replacing the template: logic then all we need to do is store a list of template IDs. if (!wp.media.gallery.templates) wp.media.gallery.templates = [‘gallery-settings’]; wp.media.gallery.templates.push(‘my-custom-gallery-setting’); Then loop through all available views wp.media.view.Settings.Gallery = wp.media.view.Settings.Gallery.extend({ template: … Read more
