like to keep reading plugin

There are three major flaws with what you’re asking: 1. You are attempting to use a WordPress API in a file loaded separately from WordPress. This will only work if you include WP in that file (resulting in the performance difference you likely expected to gain by loading a static file vs. a page/post being … Read more

remove_action in plugin file

Make sure you remove the action after the theme has added it. And use the same priority. A rather safe way is using the same action you want to clean up: add_action( ‘admin_notices’, ‘remove_woothemes_updater_notice’, 0 ); function remove_woothemes_updater_notice() { remove_action( ‘admin_notices’, ‘woothemes_updater_notice’ ); }

Reset WordPress website

One way to solve this would be to set up your demo site exactly how you want it to reset every day (use a standard username and pass like “admin” and “testpass”), and then dump the database and zip the files. Then, put the zip somewhere on your server. Set up a BASH script that … Read more

Firstly, fixing those is not essential, but it would pay to keep them in mind. For your live site WP_DEBUG should be false (development sites should have this on so that as you write the code you are warned of these things). 1) This is probably just a matter of removing the & in the … Read more

building plugin and it is displaying above plugins page

You’re using add_menu_page wrong. The function bittech_login_settings should be only: function bittech_login_settings() { add_menu_page( ‘BitTech Login Settings’, ‘BitTech Login Settings’, ‘add_users’, ‘bittech_settings’, ‘bittech_login_settings_callback’ ); } function bittech_login_settings_callback() { // content of the menu } And put the contents of the page in the callback function bittech_login_settings_callback. Also, these lines don’t make much sense: $filename = … Read more

Possible to add a language file to a plugin without adding .po/.mo files to plugin directory?

Best way to do this is probably by using a second, custom-made, plugin. Make a new plugin directory. Call it something like “example-com-custom-langs” or something unique to your site. In there, make a php file with a plugin header describing what the plugin does (for your own sanity), and do something like this: add_action(‘plugins_loaded’,’example_com_custom_langs_plugins_loaded’); function … Read more

Conditionally bypass plugin

The list of active plugins is provided by wp_get_active_and_valid_plugins() during core load and comes from active_plugins option (multisite details aside). While there is no explicit filter for it as any option it can be filtered via ‘option_’ . $option hook (so option_active_plugins) and mu-plugin (which are being loaded earlier) should be able to do it. … Read more
