Every 12+ Hours WordPress automatically goes out and checks if a plugin needs to be updated via the WordPress Repository. There’s 3 cron jobs that WordPress runs to check on things: wp_version_check – Checks for Core Updates wp_update_plugins – Check for Plugin Updates wp_update_themes – Checks for Theme Updates A neat little plugin to view … Read more
When you update a plugin you just get a new Zip-file containing the whole plugin. You don’t get the information which files in that archive changed. That’s the reason why all files are overwritten.
In your specific case, I don’t think the answer is a technical one (see my comment on the question for more details). For everyone else, the answer to “How can I easily verify a core or plugin update has not broken anything?” is automated testing. That’s the whole purpose of automated testing, because it’s unreasonable … Read more
Ok – here is a method – thanks to @Rarst for pointing me in the right direction. Include the require file if the plugins_api function is not found: if ( ! function_exists( ‘plugins_api’ ) ) { require_once( ABSPATH . ‘wp-admin/includes/plugin-install.php’ ); } Then, prepare a query to pass to plugins_api(): // set the arguments to … Read more
you got the first part right about using personal_options_update but to be on the safe side add edit_user_profile_update also. and as for sending emails within WordPress the best way would be to use wp_mail, So something like this: add_action( ‘personal_options_update’, ‘notify_admin_on_update’ ); add_action( ‘edit_user_profile_update’,’notify_admin_on_update’); function notify_admin_on_update(){ global $current_user; get_currentuserinfo(); if (!current_user_can( ‘administrator’ )){// avoid sending … Read more
You can do this: add_filter( ‘http_request_host_is_external’, ‘__return_true’ ); However, note that this disables this security feature. If you know the host or url isn’t going to change and is always going to be that, you can be more secure by checking for that explicitly: add_filter( ‘http_request_host_is_external’, ‘allow_my_custom_host’, 10, 3 ); function allow_my_custom_host( $allow, $host, $url … Read more
add_action has a priority parameter which is 10 by default, you can increase that to load your function late. Change add_action( ‘save_post’, ‘do_custom_save’ ); to add_action( ‘save_post’, ‘do_custom_save’, 100 ); Now the priority is to set to 100 and will load quite late and will allow other function associated to load before this function is … Read more
Yes it is. Though perhaps not in the way you might be thinking. If you check out some of the shared hosting sites, many of them have the capability to automatically update your WordPress site. Of course, as Milo has said, it can be rather disastrous too. Especially on a site with lots of plugins … Read more
This is a fantastic question – I’ve personally never run into this before, but here’s what I’d try, assuming: you have an image of a server that you’ve been using to spin up new instances you’re using a CDN and cloud storage for images and uploads (rather than having a local uploads folder) With those … Read more
After looking a little further I found an article on the Webmaster forums page. It has nothing to do with your hosting provider as I earlier suggested. It is 100% Google. The reason is to assist webmasters in protecting their sites by keeping up to date services. They need to make a few improvements since … Read more
