Avoid checkout for mixed backorder and normal items in Woocommerce

由 筅森魡賤 提交于 2019-12-11 01:18:55
问题 Is it possible to disable checkout if there is backorder item mixed with in stock items. The code so far is displaying message if there is mixed items in the cart, but they still can checkout the order. We are using Preorder plugin and on the settings, the preorder and onhand cant be mixed in cart. Below are settings of plugin. Prevent mixing products If you enable this option, the cart cannot contain Pre-Order products and regular products at the same time.(enabled) But it only work if there

Is Pre-Order traversal on a binary tree same as Depth First Search?

由 偶尔善良 提交于 2019-11-30 03:31:46
It seems to me like Pre-order traversal and DFS are same as in both the cases we traverse till the leaf node in a depth wise fashion. Could anyone please correct me if I am wrong? Thanks in advance! Pre-order is one type of DFS. There are three types of depth-first traversal: pre-order, in-order, and post-order. Check out here for more info. It probably depends on the definition and implementation of the depth-first algorithm. The DefaultMutableTreeNode class of the Java Swing's JTree component has the following enumeration methods used for tree traversal: depthFirstEnumeration()

When to use Preorder, Postorder, and Inorder Binary Search Tree Traversal strategies

由 柔情痞子 提交于 2019-11-28 15:01:52
I realized recently that while having used BST's plenty in my life, I've never even contemplated using anything but Inorder traversal (while I am aware of and know how easy it is to adapt a program to use pre/post-order traversal). Upon realizing this, I pulled out some of my old data-structures textbooks and looked for reasoning behind the usefulness of pre-order and post-order traversals - they didn't say much though. What are some examples of when to use preorder/postorder practically? When does it make more sense than in-order? Eric Leschinski When to use Pre-Order, In-Order, and Post
