php - add capabilitie to customer based on product categorie -

my website using wordpress, "the events calendar" plugin , "woocommerce" , manage roles , capabilities "advanced access manager" plugin.

i try add function add capability role of buyer based on product category have bought.

so try product (just bought) or event category user id, going wrong , it's impossible test step step, because process need finish let function work.

here code:

add_action('woocommerce_payment_complete', 'custom_process_order', 10, 1);  function custom_process_order($order_id) {     $order = new wc_order( $order_id );     $myuser_id = (int)$order->user_id;     $user_info = get_userdata($myuser_id);     $items = $order->get_items();      // need test :      $beta= str_replace(         ':',         '',         tribe_get_event_categories($event->id, array(             'echo'         => false,             'label'        => '',             ' label_before' => '',             'label_after'  => '',             'wrap_before'  => '',             'wrap_after'   => '',     )));     $beta = strip_tags($beta);      foreach ($items $item) {          //check if user have capabilitie         if ( ! user_can( $user_id, $capability )){              //add capability specific user             $user = new wp_user( $user_id );             $user->add_cap( $beta );         }     }     return $order_id; } 

so example customer buy product category "course_paris_night" , should have role capability "course_paris_night". capability customer access tutorial on same category example.

thanks on code or on way test ! (need learn !)

so !!! 24 april...few days later :

add_action('woocommerce_payment_complete', 'custom_process_order', 10, 1);  function custom_process_order($order_id) {     global $current_user;     global $wp_roles;      $order = new wc_order($item->id);      $order->populate($item);             $items = $order->get_items();      foreach ($items $key => $item2 ) :         $event_id_in_product = absint($item2['product_id']);     endforeach;      // trouve la catégorie du produit acheté par le stagiaire     // terms associated post in woocommerce's taxonomy 'product_cat'     $terms = get_the_terms( $event_id_in_product, 'product_cat' );      //get array of ids     $term_ids = wp_list_pluck($terms,'term_id');      //get array of parents - 0 not parent     $parents = array_filter(wp_list_pluck($terms,'parent'));      //get array of ids of terms not parents.     $term_ids_not_parents = array_diff($term_ids, $parents);      //get corresponding term objects.     $terms_not_parents = array_intersect_key($terms, $term_ids_not_parents);      //extract name of category array , post it.     foreach($terms_not_parents $term_not_parent){         $beta = $term_not_parent->name;          $alpha = strip_tags($beta);         $alpha = trim(strip_tags($alpha));         $alpha = str_replace(' - ',' ',$alpha);         $alpha = strtolower($alpha);           $all_roles = $wp_roles->roles;         $user = new wp_user( $current_user->id );         $result = $user->add_role($alpha);          return $order_id;     } } 

but don't results. testing again here has user info:

wp_user object ( [data] => stdclass object     (         [id] => 50         [user_login] => buyer.new         [user_pass] => $p$bklx7.czfvnll43ezazdmo84shzqo41         [user_nicename] => buyer-new         [user_email] => mymail@mysite.com         [user_url] =>          [user_registered] => 2016-04-23 22:05:27         [user_activation_key] =>          [user_status] => 0         [display_name] => new     )  [id] => 50 [caps] => array     (         [mycourse saint-malo intermédiaire] => 1         [mycourse paris avancé] => 1     )  [cap_key] => lep_capabilities [roles] => array     (         [0] => mycourse saint-malo intermédiaire     )  [allcaps] => array     (         [read] => 1         [level_0] => 1         [read_private_tribe_organizers] => 1         [mycourse saint-malo intermédiaire] => 1         [mycourse paris avancé] => 1     )  [filter] =>  ) 

normaly has user buying 2 new course under category "mycourse saint-malo intermédiaire" , "mycourse paris avancé" should have under "[roles] => array" 2 new roles ...but has can see it's not.

my code adding 2 new role [caps] , [allcaps] not [roles] !!!!

i sure close. idea ?

//update//

sorry !!! forgot important steps , discover not working in test code (i test directly on page not in function...will tomorrow...here it's 2.3 am)

add_action('woocommerce_payment_complete', 'custom_process_order', 10, 1);  function custom_process_order($order_id) {     global $current_user;     global $wp_roles;      $all_orders = get_posts( array(     'numberposts' => -1,         //'meta_key'    => '_customer_user',         //'meta_value'  => get_current_user_id(),         'post_type'   => 'shop_order',     'post_status' => 'completed',     ) );      $args = get_posts( array(     'numberposts' => -1,     'meta_key'    => '_customer_user',     'meta_value'  => get_current_user_id(),     'post_type'   => 'shop_order',     'post_status' => 'completed',     ) );  if( ! empty($args)){ foreach($args $item) {     setup_postdata( $item );   $order = new wc_order($item->id);  $order->populate($item);         $items = $order->get_items();  foreach ($items $key => $item2 ) :     $event_id_in_product = absint($item2['product_id']);     endforeach;        //trouve la catégorie du produit acheté par le stagiaire     //get terms associated post in woocommerce's taxonomy 'product_cat'     $terms = get_the_terms( $event_id_in_product, 'product_cat' );      //get array of ids     $term_ids = wp_list_pluck($terms,'term_id');      //get array of parents - 0 not parent     $parents = array_filter(wp_list_pluck($terms,'parent'));      //get array of ids of terms not parents.     $term_ids_not_parents = array_diff($term_ids, $parents);      //get corresponding term objects.     $terms_not_parents = array_intersect_key($terms, $term_ids_not_parents);      //extract name of category array , post it.     foreach($terms_not_parents $term_not_parent){         $beta = $term_not_parent->name;      $alpha = strip_tags($beta);     $alpha = trim(strip_tags($alpha));     $alpha = str_replace(' - ',' ',$alpha);     $alpha = str_replace('stage','stagiaire',$alpha);     $alpha = strtolower($alpha);   $all_roles = $wp_roles->roles;     $user = new wp_user( $current_user->id );     $result = $user->add_role($alpha, $alpha, array($alpha =>true,)); // array missing in previous version !  return $order_id; } } } 

this solution , it's working great under test page but...

// retrieve customer order $blc_args = get_posts( array('numberposts' => -1,'meta_key'    =>'_customer_user','meta_value'  => get_current_user_id(),'post_type'   => 'shop_order','post_status' => 'completed',) );  if( ! empty($blc_args)){ foreach($blc_args $blc_item) {     setup_postdata( $item );      $blc_order = new wc_order($blc_item->id);      $blc_order->populate($blc_item);      $blc_items = $blc_order->get_items();      foreach ($blc_items $blc_key => $blc_item2 ) :     //print_r($item2);     $event_id_in_product = absint($blc_item2['product_id']);      //get terms associated post in woocommerce's taxonomy 'product_cat'     $blc_terms = get_the_terms( $event_id_in_product, 'product_cat' );      //echo"</br>";     //echo "event id embed in product bought : " . $event_id_in_product;     //echo"</br>";      //get array of ids     $blc_term_ids = wp_list_pluck($blc_terms,'term_id');      //get array of parents - 0 not parent     $blc_parents = array_filter(wp_list_pluck($blc_terms,'parent'));      //get array of ids of terms not parents.     $blc_term_ids_not_parents = array_diff($blc_term_ids, $blc_parents);      //get corresponding term objects.     $blc_terms_not_parents = array_intersect_key($blc_terms, $blc_term_ids_not_parents);      //extract name of category array , post it.     foreach($blc_terms_not_parents $blc_term_not_parent){         $blc_start = $blc_term_not_parent->name;     }      if(preg_match("/(ultérieure|cadeau)/i", $blc_start)){      }else{         $beta = utf8_decode($blc_start);         $beta = trim(strip_tags($beta));         $beta_without_accent = strtr($beta, utf8_decode('àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ'), 'aaaaaceeeeiiiinooooouuuuyyaaaaaceeeeiiiinooooouuuuy');         $beta_with_minuscule = strtolower($beta_without_accent);         $beta_with_minuscule = str_replace('balade - ','stagiaire_',$beta_with_minuscule);         $beta_with_underscore = str_replace(' - ', '_', $beta_with_minuscule);         $beta_stagiaire = str_replace('stage','stagiaire',$beta_with_underscore);          global $current_user;          $user = new wp_user( $current_user->id );         $user->add_role($beta_stagiaire);     }     endforeach; } } 

...yes...but ! when editing , parsing in functions under child theme doesn't it. seems process because last echo appear (sometimes) , send me right "role create".

here same code build include in function.php:

add_action('woocommerce_payment_complete', 'custom_process_order', 10, 1);  function custom_process_order($order_id) {     global $current_user;      $order = wc_get_order( $order_id );     $items = $order->get_items();  //      echo"</br>"; //      echo "product id : " . ($order->id);      //$order->populate($item);      //print_r($order);      $items = $order->get_items();      foreach ($items $key => $item2 ) :     //print_r($item2);     $event_id_in_product = absint($item2['product_id']);      //get terms associated post in woocommerce's taxonomy 'product_cat'     $terms = get_the_terms( $event_id_in_product, 'product_cat' );      //echo"</br>";     //echo "event id embed in product bought : " . $event_id_in_product;     //echo"</br>";      //get array of ids     $term_ids = wp_list_pluck($terms,'term_id');      //get array of parents - 0 not parent     $parents = array_filter(wp_list_pluck($terms,'parent'));      //get array of ids of terms not parents.     $term_ids_not_parents = array_diff($term_ids, $parents);      //get corresponding term objects.     $terms_not_parents = array_intersect_key($terms, $term_ids_not_parents);      //extract name of category array , post it.     foreach($terms_not_parents $term_not_parent){         $start = $term_not_parent->name;                 }      //echo"</br>";     //echo "product category : " . $start;     //echo"</br>";      if(preg_match("/(ultérieure|cadeau)/i", $start)){ //echo"</br>";     //echo "don't add product category : " . $start;     //echo"</br>";     }else{     $beta = utf8_decode($start);     $beta = trim(strip_tags($beta));     $beta_without_accent = strtr($beta, utf8_decode('àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ'), 'aaaaaceeeeiiiinooooouuuuyyaaaaaceeeeiiiinooooouuuuy');     $beta_with_minuscule = strtolower($beta_without_accent);     $beta_with_minuscule = str_replace('balade - ','stagiaire_',$beta_with_minuscule);     $beta_with_underscore = str_replace(' - ', '_', $beta_with_minuscule);     $beta_stagiaire = str_replace('stage','stagiaire',$beta_with_underscore);      echo"</br>";     echo "role create : " . $beta_stagiaire;     echo"</br>";      $user = new wp_user( $current_user->id );      $user->add_role($beta_stagiaire);     }     endforeach;   return $order_id;  } 

and has can imagine test it's not easy because have payment process.

any error let somewhere ? don't see it.
