hoping knockout.js guru can shed light on this

i trying make contact objects go contact observable array, observable array within contactgroup object, dont understand how this? possible, or approaching wrong way? thanks!

var json =       {"contactgroups" : [      {              "name" : "contact group",              "contact" : [                      {                              "name" : "aaaa",                              "email" : "",                              "telephone" : "",                              "mobile" : "",                              "mail_group" : "",                              "comment" : ""                      },                      {                              "name" : "bbbb",                              "email" : "",                              "telephone" : "",                              "mobile" : "",                              "mail_group" : "",                              "comment" : ""                      },                      {                              "name" : "cccc",                              "email" : "",                              "telephone" : "",                              "mobile" : "",                              "mail_group" : "",                              "comment" : ""                      }              ]      }  ]}    function technicalviewmodel(){     self = this;      var contactgroups = ko.utils.arraymap(json.contactgroups, function(item) {         var group = new contactgroup(item);         var contacts = ko.utils.arraymap(item.contact, function(item) {         return new contact(item)         });         group.contact(contacts)         return group;     })     self.contactgroups(contactgroups)      function contactgroup(data){         var self = this;          self.name = ko.observable(data.name);         self.contact = ko.observablearray([]);          function contact(data){             this.name = ko.observable(data.name);             this.email = ko.observable(data.email);             this.telephone = ko.observable(data.telephone);             this.mobile = ko.observable(data.mobile);             this.mail_group = ko.observable(data.mail_group);             this.comment = ko.observable(data.comment);         }         } }  technicalview = new technicalviewmodel ko.applybindings(technicalview);

you have move contact function outside of contactgroup function. it's scope limited within contactgroup function , not able seen ko.utils.arraymap function. moving outside increases scope entire technicalviewmodel.

function technicalviewmodel(jsondata){     self = this;      var contactgroups = ko.utils.arraymap(jsondata.contactgroups, function(item) {         var group = new contactgroup(item);         var contacts = ko.utils.arraymap(item.contact, function(item) {             return new contact(item)         });         group.contact(contacts)         return group;     });      self.contactgroups = ko.observablearray(contactgroups);      function contact(data) {         this.name = ko.observable(data.name);         this.email = ko.observable(data.email);         this.telephone = ko.observable(data.telephone);         this.mobile = ko.observable(data.mobile);         this.mail_group = ko.observable(data.mail_group);         this.comment = ko.observable(data.comment);     }      function contactgroup(data){         var self = this;          self.name = ko.observable(data.name);         self.contact = ko.observablearray([]);     } }  var technicalvm = new technicalviewmodel(json); ko.applybindings(technicalvm);

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
