I’m just assuming here but this is usually done by fingerprinting for specific version files/directory’s/code and sometimes even size. For example you can remove all the meta versions tags ( isn’t there like 12 places) and .txt file for 3.1 but since 3.1 is the only version to include the following new file by default, … Read more
WordPress.org offers an api that includes a version checker. That version checker can return a json response (or a serialized string if that’s your thing). Example usage $url=”https://api.wordpress.org/core/version-check/1.7/”; $response = wp_remote_get($url); $json = $response[‘body’]; $obj = json_decode($json); The resulting $obj will contain an offers array, whose first element is an object that contains the information … Read more
I finally found a solution to this problem and thought I would post my solution for anyone looking for assistance. My main website sits on /public_html on my server I was installing new sites on a subdomain (e.g. newwebsite.com.au) in a sub-directory: /public_html/sites/newwebsite.com.au Even though /public_html/sites/newwebsite.com.au was the root directory for the subdomain: newwebsite.com.au for … Read more
It looks like after switching code to check get_site_transient(‘update_core’) I have got what I need just action must be executed in a proper priority or a hook (thoughts/suggestions?). Working code below: function core_update_notification(){ global $wp_version; $installed_version = $wp_version; $uc_transient = get_site_transient(‘update_core’); if ( empty($uc_transient->updates) ) return; $updates = $uc_transient->updates; $current_version = $updates[0]->current; if (version_compare($installed_version, $current_version, … Read more
If your current plugin version is 1.2.5, and you have a beta version for the next version, it should be called 1.2.6-beta. Your user can install it, and when the real 1.2.6 version is released on the repository, WordPress will notify the user on the Plugins page and let him update. WordPress uses a PHP … Read more
The function checks your version of WP for possible updates. It appears that there is a transient in the database named ‘update_core’, so it’s stored in the $wpdb->options table as ‘_site_transient_update_core’. The value of that transient is a serialized object that has information, I’m not an expert on wp_version_check, but it uses that transient to … Read more
Supporting old versions of WordPress seems reasonable, but is it really necessary? Personally, I think supporting old versions is waste of efforts and time and it prevents end-users from updating their WordPress installs. What’s the point of being a WordPress developer if you’re encouraging users to remain using insecure and out-of-date versions? Just adding a … Read more
You can check for the current handle before removing the version. Here’s an example (untested): add_filter( ‘style_loader_src’, ‘sdt_remove_ver_css_js’, 9999, 2 ); add_filter( ‘script_loader_src’, ‘sdt_remove_ver_css_js’, 9999, 2 ); function sdt_remove_ver_css_js( $src, $handle ) { $handles_with_version = [ ‘style’ ]; // <– Adjust to your needs! if ( strpos( $src, ‘ver=” ) && ! in_array( $handle, $handles_with_version, … Read more
Always write plugins for the current version and keep the nightly builds from the upcoming versions in mind. Anything else doesn’t matter. Edit As @toscho pointed out in a comment: There might be some explanation needed to why it is that way. Because I say so. Plugins only need to be compliant with core because … Read more
If you need to get the wordpress version in your script, there is a global variable: $wp_version (right now it’s something like ‘3.1-RC3-17376′) It contains the wordpress version. If you need to acquire if from a file, you can read it from /wp-includes/version.php: function getWPVersion() { $path=”/path/to/wp-install”; include $path.’/wp-includes/version.php’; return $wp_version; } WordPress Version Variables … Read more
