Via the “Annotate” function the the Trac, you can see that this was added three years ago, after the request for a generic POST handler that plugins can use. Google code search tells me that at least Akismet uses this hook, and it appeared there at the time it was introduced in core. It works … Read more
adding these functions should do the trick. First things first, add this line to functions.php while you are working on this: add_action(‘init’, ‘flush_rewrite_rules’); What that code will do is constantly flush the rewrite rules, it makes this easier to test while you are working on it, instead of having to go in and manually reset … Read more
First of all, provide a well-formed default HTML form. Use <label>, <fieldset> and <legend> where appropriate. This markup provides a good structure for CSS styling. Adding in some CSS classes may help too. Provide a filter that allows developers to tweak the default form. To go even further, you can allow developers to completely rewrite … Read more
Have you thought about using feedburner? I’m using feedburner to handle subscribers. And it emails subscribers once a new post is made. You should be able to import your subscribers by emailing the csv file to [email protected] and informing support that you are moving to use Feedburner.
A subtle difference between your syntax wp-footershould be wp_footer, underscore _ and not hypthen – add_filter(‘wp-footer’, fahad); // wrong… add_filter(‘wp_footer’, ‘fahad’); // right.. Follow the naming convention of functions: (Codex) Plugin_API: Action_Reference » the wp_footer hook (Codex) Plugin_API: Action_Reference (Codex) Function_Reference
Previous versions of WordPress didn’t really provide a good means to conditionally enqueue stylesheets and JavaScript within a plugin (i.e. only when needed). So most plugin authors enqueued both on every WordPress init/load, even if the plugin wasn’t being used on a given page. Current versions of WordPress allow for enqueuing later in the flow … Read more
You can look at the Codex. Encodes < > & ” ‘ (less than, greater than, ampersand, double quote, single quote). Will never double encode entities. Given that, arguably, both of those strings need sanitization. Imagine a site name like >> “My” Website’s Great Title <<” Also, since you are using this in Javascript, you … Read more
Make it as simple as possible for theme developers. Most are not programmers. There are two very simple options: add_theme_support() and get_theme_support() Provide an identifier and some options. Let’s say your identifier is drtanz_plugin. A theme author could now add the following to her theme’s functions.php: add_action( ‘after_setup_theme’, ‘prefix_register_theme_support’ ); function prefix_register_theme_support() { add_theme_support( ‘drtanz_plugin’, … Read more
It´s possible select which plugin load by page or post […]? Short answer: Not with a plugin (nor with code in a theme). Normally, in WordPress, you use conditional tags to undestand in which post or page you are, e.g. you can use is_page(‘my-page’) or is_post(12) and so on. The problem is these conditional tags … Read more
Solved it, using pre_get_posts filter and WP_Query->set() method function foo_filter_orders($query) { global $pagenow; $qv = &$query->query_vars; $currentUserRoles = wp_get_current_user()->roles; if (in_array(‘shop_manager’, $currentUserRoles)) { if ( $pagenow == ‘edit.php’ && isset($qv[‘post_type’]) && $qv[‘post_type’] == ‘shop_order’ ) { $query->set(‘meta_key’, ‘handle_by’); $query->set(‘meta_value’, ‘shopmanager1’); } } return $query; } add_filter(‘pre_get_posts’, ‘foo_filter_orders’);
