首先我們要知道什么是分銷系統(tǒng)？
分銷系統(tǒng)指通過互聯(lián)網(wǎng)將供應(yīng)商與經(jīng)銷商有機(jī)地聯(lián)系在一起，為企業(yè)的業(yè)務(wù)經(jīng)營及與貿(mào)易伙伴的合作提供了一種全新的模式。供應(yīng)商、分支機(jī)構(gòu)和經(jīng)銷商之間可以實(shí)現(xiàn)實(shí)時(shí)地提交業(yè)務(wù)單據(jù)、查詢產(chǎn)品供應(yīng)和庫存狀況、并獲得市場、銷售信息及客戶支持，實(shí)現(xiàn)了供應(yīng)商、分支機(jī)構(gòu)與經(jīng)銷商之間端到端的供應(yīng)鏈管理，有效地縮短了供銷鏈。
知識付費(fèi)的分銷功能主要體現(xiàn)在專題課程及會(huì)員模塊；用戶購買專題課程、會(huì)員后會(huì)給用戶的上級和上上級返傭。
那么分銷系統(tǒng)是如何實(shí)現(xiàn)的呢？
知識付費(fèi)系統(tǒng)中在用戶進(jìn)入系統(tǒng)時(shí)若是帶有上級的信息，那么這個(gè)用戶就是別的用戶發(fā)展的下級，我們就需要記錄該用戶的上級信息。數(shù)據(jù)庫用戶表eb_user表中有字段spread_uid（推廣員id）,該字段記錄的是用戶的上級id。
首先確定什么時(shí)候執(zhí)行分銷功能？分銷功能執(zhí)行肯定是需要訂單結(jié)束后，這樣可以避免大多數(shù)用戶退款后的傭金返還問題。
然后就是分銷代碼的書寫了，知識付費(fèi)分銷分為人人分銷和指定分銷；人人分銷是指系統(tǒng)中的所有用戶均可參與分銷活動(dòng)，并且在下級用戶購買后可以獲得傭金。指定分銷是指只有系統(tǒng)設(shè)置推廣權(quán)限的用戶才能在下級用戶購買后獲得傭金。因?yàn)橹R付費(fèi)的分銷是二級分銷，所有我們是直接寫了一級返傭和二級返傭的方法，在執(zhí)行完一級返傭后執(zhí)行二級返傭，這是分銷的最簡單邏輯了。
以專題課程為例，在專題課程購買成功后執(zhí)行返傭。

這樣專題課程的二級分銷就完成了，若是想再加第三級分銷，我們一樣的邏輯，獲取二級的上級，然后判斷返傭即可。
