>您想在客戶(hù)結(jié)帳之前在WooCommerce商店中設(shè)置某種最低要求。接下來(lái)是有關(guān)如何設(shè)置這些要求和限制的指南，而無(wú)需完全使用任何插件：

• 設(shè)置每個(gè)訂單的最小重量要求
• 設(shè)置最少每訂單所需的產(chǎn)品數(shù)量
• 設(shè)置最小數(shù)量
• 設(shè)置每個(gè)訂單的最低美元金額

鑰匙要點(diǎn)

在不使用插件的情況下，可以在WooCommerce中設(shè)置最低要求，從而可以更好地控制和自定義結(jié)帳過(guò)程。這包括設(shè)置每個(gè)訂單的最小重量要求，每訂單所需的最低產(chǎn)品數(shù)量，每種產(chǎn)品的最低數(shù)量以及每訂單的最低美元金額。
該過(guò)程涉及使用WooCommerce提供的“ Woocommerce_check_cart_items”操作來(lái)運(yùn)行函數(shù)和執(zhí)行代碼。該代碼應(yīng)放置在主題的functions.php文件中，并與WordPress和WooCommerce的最新版本兼容。
• > 特定的WooCommerce功能可用于設(shè)置最低要求，例如重量，產(chǎn)品數(shù)量，產(chǎn)品數(shù)量和總購(gòu)物車(chē)價(jià)值。每個(gè)要求都有其自己的功能，該功能會(huì)檢查購(gòu)物車(chē)項(xiàng)目并將其比較它們與設(shè)定的最低要求，如果不滿(mǎn)足要求，請(qǐng)顯示錯(cuò)誤消息。
WooCommerce還提供了為特定產(chǎn)品或類(lèi)別設(shè)置最小和最大數(shù)量的靈活性，在產(chǎn)品頁(yè)面上顯示數(shù)量要求，并以編程方式更新產(chǎn)品庫(kù)存。這些可以通過(guò)內(nèi)置功能或諸如“ WooCommerce Min/Max Wartities”和“ WooCommerce數(shù)量增量”之類(lèi)的插件來(lái)實(shí)現(xiàn)。>
>本文中使用的方法
>總是有一種不止一種在WooCommerce中設(shè)定最低要求的方法；結(jié)果甚至可能是相同的。但是我認(rèn)為下面描述的方法是正確（或更好）這樣做的方法。始終歡迎并獲得有關(guān)如何完成這些任務(wù)或進(jìn)一步改進(jìn)的任何建議。

>以下代碼已在可用于WordPress（3.9.1）和WooCommerce（2.1.12）的最新版本中進(jìn)行了測(cè)試。安裝插件時(shí)，我們將使用為WooCommerce提供的虛擬數(shù)據(jù)。該代碼應(yīng)輸入您的主題函數(shù)。php文件，并且對(duì)其進(jìn)行了大量評(píng)論，因此在需要時(shí)更容易遵循和/或修改。

>我們將使用WooCommerce_Check_cart_items操作由WooCommerce提供的操作來(lái)運(yùn)行我們的功能并執(zhí)行我們的代碼。訪問(wèn)以下鏈接以獲取WooCommerce操作和過(guò)濾器的完整列表，也稱(chēng)為掛鉤。

設(shè)置每個(gè)訂單的最小重量要求

>通常限制客戶(hù)完成結(jié)帳過(guò)程而不滿(mǎn)足最小權(quán)重要求是有用的。減小的重量要求可以幫助您的運(yùn)輸成本更易于管理，并且運(yùn)輸過(guò)程更加精簡(jiǎn)。不要忘記將最小的重量要求更改為最適合您的一切，并記住，在WooCommerce下設(shè)置的任何重量單元 - >設(shè)置 - > Products-> Products。
