php - Updating WooCommerce cart after adding a variable product (AJAX) -

-

i overriding ajax function add product using woocommerce can send attributes cart (which doesn't work out of box).

i followed instructions on update woocommerce cart after adding variable product via ajax - want - doesn't work completely.

everything when logged out. when log wordpress php override doesn't work/gets ignored. no errors , no product added cart. tried many different approaches, nothing helps.

function ajax_add_to_cart_script() {     $vars = array( 'ajax_url' => admin_url( 'admin-ajax.php' ) );     wp_enqueue_script( 'wc-variation-add-to-cart', get_template_directory_uri() . '/js/jquery.add-to-cart.js', array( 'jquery' ), null, true);     wp_localize_script( 'wc-variation-add-to-cart', 'wc_variation_add_to_cart', $vars ); }  add_action( 'wp_enqueue_scripts', 'ajax_add_to_cart_script' ); add_action( 'wp_ajax_nopriv_woocommerce_add_variation_to_cart', 'so_27270880_add_variation_to_cart' );  function so_27270880_add_variation_to_cart() {     ob_start();      $product_id        = apply_filters( 'woocommerce_add_to_cart_product_id', absint( $_post['product_id'] ) );     $quantity          = empty( $_post['quantity'] ) ? 1 : wc_stock_amount( $_post['quantity'] );     $variation_id      = isset( $_post['variation_id'] ) ? absint( $_post['variation_id'] ) : '';     $variations        = ! empty( $_post['variation'] ) ? (array) $_post['variation'] : '';     $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $product_id, $quantity );      if ( $passed_validation && wc()->cart->add_to_cart( $product_id, $quantity, $variation_id, $variations ) ) {          do_action( 'woocommerce_ajax_added_to_cart', $product_id );          if ( get_option( 'woocommerce_cart_redirect_after_add' ) == 'yes' ) {             wc_add_to_cart_message( $product_id );         }          // return fragments         wc_ajax::get_refreshed_fragments();      } else {          // if there error adding cart, redirect product page show errors         $data = array(             'error' => true,             'product_url' => apply_filters( 'woocommerce_cart_redirect_after_error', get_permalink( $product_id ), $product_id )         );          wp_send_json( $data );      }      die(); }

i making sure add_action( 'wp_ajax_nopriv_woocommerce_add_variation_to_cart', 'so_27270880_add_variation_to_cart' ); added before snippet make sure gets fired, works when logged out - not when logged in.

anyone got clue why?

ping @helgatheviking

an update, seems work if add following functions.php

add_action( 'wp_ajax_nopriv_woocommerce_add_variation_to_cart', 'so_27270880_add_variation_to_cart' ); add_action( 'wp_ajax_woocommerce_add_variation_to_cart', 'so_27270880_add_variation_to_cart' );

meaning, 1 logged in admins , 1 normal users. not sure why need both because every example have seen kind of extension/override mentions wp_ajax_nopriv_$function

hope helps have same problem me. , if explain me why needed, happy hear it.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
