You could always use an uninstall.php file for the plugin instead. http://codex.wordpress.org/Function_Reference/register_uninstall_hook If the plugin can not be written without running code within the plugin, then the plugin should create a file named ‘uninstall.php’ in the base plugin folder. This file will be called, if it exists, during the uninstall process bypassing the uninstall hook. … Read more
I won’t comment on all features, but I will say take a look through the changelogs for WooCommerce, our blog, and our public GitHub repository to get an idea of the features we’ve added, what we’re currently developing, and the over-all direction we’re taking with WooCommerce. A few of the features we’ve added to our … Read more
First of all – plugins are for generating content, themes are for displaying it. So really, a plugin shouldn’t do this. But there are grey areas – for example in an ‘events’ related plugin, it would be desirable to display dates, venue etc – things that a WordPress theme wouldn’t normally display. I would suggest … Read more
This happens because plugins_loaded fires before the global variable $wp_rewrite exists. From wp-settings.php: // Load active plugins. foreach ( wp_get_active_and_valid_plugins() as $plugin ) include_once( $plugin ); unset( $plugin ); // Load pluggable functions. require( ABSPATH . WPINC . ‘/pluggable.php’ ); require( ABSPATH . WPINC . ‘/pluggable-deprecated.php’ ); // Set internal encoding. wp_set_internal_encoding(); // Run wp_cache_postload() … 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.

Inside the is_purchasable() method in the product class is a filter. By default the product is not purchasable if there is no price set at all, but that can … Read more
No, the wordpres.org SVN repositories are not for development and there are no plans to change this. So you either have to ask on support forum, or if the plugin is on an open GIT repository search for it on GitHub.
No, escaping should happen at the moment of output ( late escaping ) so that we know that it only occurs once. Double escaping can allow specially crafted output to break out. By escaping, we’re talking about functions such as esc_html, wp_kses_post, esc_url, etc. Sanitizing functions and validating functions are not the same, e.g. sanitize_textfield. … Read more
function self_deprecating_sidebar_registration(){ register_sidebar( /* Your arguments here */ ); } add_action( ‘wp_loaded’, ‘self_deprecating_sidebar_registration’ ); Most themes will register the sidebar in their functions file, which is included before init but after plugins are loaded. Hooking onto wp_loaded should guarantee that your sidebar is registered after the theme’s.
I asked a similar but broader question, and I still need to research and write a complete answer. In the meantime here are some pointers that might help you: I wrote a set of plugins that resizes all images to the size used in the editor. It works by converting <img src=”https://wordpress.stackexchange.com/questions/4984/image.jpg” width=”200″ height=”400″/> to … Read more
