TLDR: Use a cookie Why Not PHP Sessions? PHP sessions don’t work on most hosts ( e.g. WP Engine which say in their docs they do not support PHP sessions ). PHP sessions are incompatible with caching CDNs, caching proxies such as Varnish, and caching plugins. They rely on a session ID stored in a … Read more
Remove your session_start() and at the beginning of your functions.php put this: if (!session_id()) { session_start(); } For use from a plugin use this: function register_session(){ if( !session_id() ) session_start(); } add_action(‘init’,’register_session’);
By default the login cookie lasts for 14 days if you tick ‘remember me’ 48 hours if you don’t So as a short term fix you probably want to tick ‘remember me’, and to extend that to 30 days you can add an auth_cookie_expiration filter e.g. function auth_cookie_expiration_30_days( $seconds, $user_id, $remember_me ) { if ( … Read more
The wp_generate_auth_cookie() function is a pluggable function, meaning you can define a function with the same name in a plugin and your version will be used instead of the WordPress core function. The number of pluggable functions is limited, however. If you want a broad solution that works for all cookies, your lower-level Lua approach … Read more
SOLVED This is how I did it. Getting the cart content. $cart_content = WC()->cart->cart_contents; Replacing the cart item with the new updated version. $cart_content[$cart_item_key] = $cart_item; This here made the change. Setting the updated cart content. WC()->cart->set_cart_contents($cart_content);
The only way to make this go away is to not use PHP sessions and use cookies directly instead. PHP sessions are fundamentally incompatible with a lot of page caching and CDN mechanisms e.g. cloudflare, Varnish, or full page caching plugins such as batcache or WP Supercache. PHP Sessions are also turned off and disabled … Read more
The is_author() conditional can be used to check if the query is targeting an author’s page. By passing one or more User IDs/nicenames into it, it will check for specific author pages. So to check if the current author page is for the current user, it can be passed the return value from get_current_user_id(): if … Read more
In WordPress you need to start the session with if ( !session_id() ) { session_start(); } in order to use session variables. You can enter this code into wp-config See http://www.frank-verhoeven.com/using-session-in-wordpress
if ( empty($_SESSION[‘r1’]) ) { global $query_string; query_posts($query_string . “&cat=-” . $id); } This should work, depending on $id is set.
Although I realise this is probably not the right way to go about it, I managed to turn on output buffering using the following code in my plugin: add_action(‘init’, ‘rsq_buffering’); function rsq_buffering() { ob_start(); } I probably should be doing any session stuff from within the init hook instead of just all over the place.
