i can sort of see logic in displaying plugin information via shortcode. i'd assume putting shortcode on post, add echo do_shortcode post file. what don't understand when there no shortcode, such rating plugin using. the plugin has folder in website information stored. information displayed on front page (post rating) there no code in index.php calls of plugin files. where wordpress call plugin files loaded , how can see file being loaded? the vast majority of plugins use hooks in order implement functionality. can find list of these hooks on wordpress developer site here . one of commonly used examples wp_enqueue_scripts , used implement front-end styling , javascript files. take wordpress stack exchange , here , more information on how filters , hooks powered.

in golang, possible refresh part of template when variable updated ? can find in angular.js instance. basically in code, lookup adresses postcode in ajax, display list of addr found postcode. here sample of template : at moment, ajax calls go routine. don't want result in js , build html result of ajax call. i like, if possible, update addresses value (it's array) build list of addr dynamically. any clue ? the template engine not support out-of-the-box. so have implement yourself. it's not hard. here steps should follow achieve it: 1. refactor templates separate template renders addresses on own using {{define "name"}} action. may put in different template file , include in current place using {{template "name"}} action, or may leave in original place , use new {{block "name" pipeline}} t1 {{end}} action (introduced in go 1.6) defines template , executes @ once. 2. modify/create handlers make sure have hand

i have following situation: person model includes userable : class person < activerecord::base include userable end this userable has many emails: module userable extend activesupport::concern included has_one :user, as: :userable has_many :emails, as: :emailable, dependent: :destroy end end email has model too: class email < activerecord::base belongs_to :emailable, polymorphic: true validates :address, presence: true, format: { with: /\a[a-za-z0-9._%+-]+@([a-za-z0-9.-]+\.)+[a-za-z]+\z/} end and finally, user model: class user < activerecord::base # devise properties devise :database_authenticatable, :rememberable, :trackable, :timeoutable, :recoverable end i'm trying create "forgot password" thing recover user password sending email user. problem 'email' not method @ user . so, when load path "users/password/new" gives me error: undefined method `

i have list in excel , i'd select higher 3 results, , 3. seems easy conditional formatting in example: 1 | 2 | 3 | 4 | 5 | 6 44 | 78 | 98 | 45 | 52 | 98 where 2nd, 3rd , 6th number highlighted. the problem appears this: 1 | 2 | 3 | 4 | 5 | 6 44 | 78 | 78 | 45 | 87 | 98 excel highlight 2nd, 3rd, 5th , 6th number, because first 2 (the third on sorted list) equal. how can make excel select 1 of them? (the solution doesn't need use conditional formatting, tools available on excel can used, formulas vb, simplicity it's desirable). for conditional formatting, need break tie. 1 way count number of times value appears in previous comparisons. this change conditional formula to =(rank(a2,$a$2:$f$2)+countif($a$2:a$2,a2)-1)<=3 note absolute positions used in cases, , relative in others. breakdown: rank(a2,$a$2:$f$2) - rank formula. know one, you're using now countif($a$2:a$2,a2) - count number of times value appears - note refere

i must read .mdb file on 15 minutes interval. problem file emptied each day @ 15:45 pm. , somehow loose data in interval gap. i have searched cron jobs/scheduled task on server , found nothing know if there way set .mdb database empty @ specific time? thanks there no built-in way configure access database empty itself. has done either vba-code/macros inside database or external application/script accessing database , deleting everything. if database emptied @ specific time without user interaction, there has kind of scheduled task this. if absolutely data deleted, might possible whole database overwritten fresh/empty template somewhere. - still has done scheduled task. if database stored on network share, accessible other computers, task deleting data might run on computer.

i making client server application. in application if client went down server try reconnect ( i.e. if recv() on server side returns 0 value server go accept connection ). want modify server allowing connect multiple clients. thought of using poll() server check on each client sometime. wanted know poll how can check if connection client lost? when use multiplex io poll , can handle connection shutdown following events: pollin when there data read, , when read or recv function call, make sure checked return value, typically return value of 0 indicates connection has been shutdown. same previous single client version. pollrdhup indicates peer has closed connection, or shut down writing half of connection. pollerr other errors. when 3 event triggered, means client has closed connection or there errors on socket, typically close sockets.
