As the other answers seem to imply, there is no built-in way to do this. There is no theme uninstall API similar to that for plugins. There is actually a long-standing ticket to get this feature added to WordPress core, so that themes can uninstall themselves. The consensus from the lead developers there seems to … Read more
You are asking two questions. The one being how can you test an update and the other being how can you run code after an update. You can test a theme update by pushing the updates out your self and testing it if it works. You can do that by using GitHub Updater. If you … Read more
Try hooking on all these: (But I guess you’d have to do it from a plugin, since doing it from theme functions.php might be too late). E.g.: /* Plugin Name: test Description: switchtest Version: 0.1.0 */ add_filter( ‘template’, ‘yourthing_switch_theme’ ); add_filter( ‘option_template’, ‘yourthing_switch_theme’ ); add_filter( ‘option_stylesheet’, ‘yourthing_switch_theme’ ); add_filter( ‘pre_option_stylesheet’, ‘yourthing_switch_theme’ ); function yourthing_switch_theme( $theme … Read more
You can use PHP’s output buffering. WIth this you can write a wrapper for the get_head() function function wpse251841_wp_head() { ob_start(); wp_head(); return ob_get_clean(); } You can then use this as $data = array( ‘wpHead’ => wpse251841_wp_head(), ‘postContent’ => $post->post_content, ‘postContentFiltered’ => apply_filters( ‘the_content’, $post->post_content ) ); Reference: Output Control Functions

Actually, I just did something like this for a Drupal site. I based my truncation function on this: Truncate text preserving HTML tags with PHP Use the final version of the function at the end of the comments. The function takes its $length parameter in characters, not words, but you can probably use the general … Read more
You mean you call your class right before closing HTML tag? It is too late to enqueue scripts then. Don’t hook into wp_print_scripts to enqueue your scripts and styles. I just learned this today from Rarst. So change your init_hooks function to something like following: public function init_hooks() { add_action(‘wp_enqueue_scripts’, array(__CLASS__,’include_all_files’)); } Also you are … Read more
Ok, just noticed that you’re wrapping the URL in single quotes, so the $username variable won’t get interpreted. Try this instead: wp_remote_get(‘https://twitter.com/statuses/user_timeline/’. $username .’.json’); Or use double quotes instead of single.
if you are asking default background image for add_theme_support( ‘custom-background’); then it can be set using ‘default-image’ => get_template_directory_uri() . ‘/images/pattern.png’, complete code will look like below. $args = array( ‘default-color’ => ‘f0f0f0’, ‘default-repeat’ => ‘fixed’, ‘default-image’ => get_template_directory_uri() . ‘/assets/images/pattern.png’, ); add_theme_support( ‘custom-background’, $args );
Instead of using jQuery to update the value of the custom input, use the wp.customize object’s set() function (found in customize-base.js): wp.customize( key, function ( obj ) { obj.set( newValue ); } ); Where key is the setting, and newValue is the updated value. Also, worth noting, in the class that extends WP_Customize_Control, make sure … Read more
