Short answer: You can’t. That’s not hookable for the settings cookies. You can adjust the cookie paths and such via defines, so as to make the settings apply across multiple installations across a domain. The most common use of this is to make logins work across a domain, so when you log into one, you … Read more
Even more easy: open up the specific plugin directory; find the php file in which the version of the plugin is mentioned; change the version number to a high number (i.e. Version 1.1 to Version 100.1)
Try to keep the business logic out of the theme. Dealing with images is always an edge case, because they do affect presentation, which is usually a theme job. But the logic of how to get and order these images, the JavaScript parts and the backend are probably better in a separate code base. That … Read more
I’m not entirely sure what you want to do exactly. But basically you just create one instance and then add functions like public static function FunctionName() to be used anywhere you want after the plugin got activated. To fire your hooks simply use the public function __construct(). Taking the Sample Plugin from below, the FooBar … Read more
I pretty sure this filter lets you add an array of variables. I’ve not tested this: function add_custom_query_vars( $vars ){ $vars[] = “variable1”; $vars[] = “variable2”; $vars[] = “variable3”; //… etc return $vars; } add_filter( ‘query_vars’, ‘add_custom_query_vars’ ); Or another way of doing it would be to do this: function add_custom_query_vars( $vars ){ array_push($vars, “variable1”, … Read more
Code in functions.php and plugins works in almost exactly same way (except than stage at which it is loaded and some plugin-specific hooks). Basically you just take your code out of functions.php, place it in plugin and it still works. It is good practice to use naming conventions and checking for functions definitions so it … Read more
I personally just add a menu link and in the function for it handle the form. With $_SERVER[‘REQUEST_URI’] as the action. Example below. add_action(“admin_menu”, “menu” ); function menu(){ add_menu_page(‘Test form’, ‘Test form’, ‘manage_options’, ‘show_form’ ); } function show_form(){ if ( $_SERVER[“REQUEST_METHOD”] == “POST” ){ print “do stuff”; } else { ?><form method=”post” action=”<?php echo $_SERVER[‘REQUEST_URI’]; … Read more
Try esc_html( $string ) (Codex ref), which among other things encodes single- and double-quotes. For further reference, see the Data Validation entry in the Codex.
The reason the WordPress test bootstrap is loaded at the end is precisely because it loads WordPress: // Load WordPress require_once ABSPATH . ‘/wp-settings.php’; If you don’t hook your function to load your plugin to ‘muplugins_loaded’ before including the bootstrap, your plugin won’t be loaded with WordPress. In most cases that will mean that your … Read more
wp_loaded fires for both the front-end and admin section of the site. This action hook is fired once WordPress, all plugins, and the theme are fully loaded and instantiated. Since you’re checking for plugin updates, it might be best to hook into admin_init instead of wp_loaded — assuming you want to know if a user … Read more
