If you’re going to add the nonce field to an HTML string, you have to specify that you don’t want it echoed. That’s the fourth parameter; see https://core.trac.wordpress.org/browser/tags/3.3.1/wp-includes/functions.php#L1952 $formDisplay .= wp_nonce_field( ‘contact-form’, ‘_wpnonce’, true, false );
If you’re inside a plugin, WordPress is already loaded. You don’t need to load it yourself. Inside whatever function needs the user ID, you need to do two things: Globalize the user data variable Populate the user data variable Here’s some pseudocode: function some_function_that_needs_user_info() { global $current_user; get_currentuserinfo(); // Now reference $current_user->ID in your code. … Read more
Without seeing your show_sticky_posts, show_lastest_posts, show_lastest_missions,show_all_posts_from_categories i can guess that the shortcode content is always before the post content beacuse this functions are echoing/outputing the result and a shortcode should return content instead so you can try using output buffer of PHP like this: function show_posts_handler( $atts, $content=null, $code=”” ) { //code 4 displaying extract( … Read more

I’m posting this answer because the accepted answer is slightly misleading, as it implies that you cannot use the trademarked name at all. While not 100% wrong, it’s also not 100% right. It is correct that unless you are WooCommerce, you can’t call your plugin “WooCommerce Cool Add-on”. But you can call it “Cool Add-on … Read more

The Codex lacks a lot of functions in the function reference. On some places you already got the 3.1 explanations, on other completely outdated stuff. … Read more
First use add_options_page() – shorter wrapper, better practice. Second you need to save its return in some (global or static) variable. That is often used thingie and confusingly referenced by different names in documentation. Global $hook_suffix holds such value for current page. function create_admin_pages() { global $my_page; $my_page = add_options_page(… From there it is something … Read more
dirname( STYLESHEETPATH ); That will return the theme directory. Never assume /wp-content/ below ABSPATH. I’m using often a different directory and domain for wp-content to enable cookieless requests to theme files. Bad plugins and themes break terribly in such cases. Addendum Or use get_theme_root() for the file path and get_theme_root_uri() for the URI. Both are … Read more
I sort of fixed your query. It needs a table and a WHERE condition to prevent changing all rows. Even a LIMIT 1 at the end won’t hurt. $rows_affected = $wpdb->query( $wpdb->prepare( “UPDATE {$table} SET removed = %s, post_id = %d, user_id = %d, status = %d;”, $cur_date = date(‘Y-m-d H:i:s’), $postid, $userid, 0 ) … Read more
