Ztree + PHP Infinite pole node recursive lookup node method
First, preface
A simple description, the practice of a few principles, thinking, actually write a lot of things, thought is the most important.
1, Target: Will write an infinite node tree directory structure, such as
Steps:
1, your download plugin ztree. And then decorate it in your project.

Read a novel A few days ago, there are some imagination about time and space; see the story inside I think, now the world's data is getting bigger, then there is no one in the limited volume storage media to achieve unlimited storage data! To this end I also deliberately to check the information on the Internet. There are some assumptions about infinite space on the internet, but there is little or no information about the number of data stored. So I
When solving a problem, you usually have a situation where you are set to infinity. This time is usually set with 0x7fffffff, he is the computer 32-bit integer maximum number, the equivalent of Int_max. But in many cases this setting is not optimal and can lead to bugs because we sometimes want infinity + infinity = infinity, For example, in the prim algorithm or the Dijstra algorithm on the edge of the slack operation, this time Int_max arbitrarily add a number will overflow, resulting in a wro
Problem: Design the company's staff table, employees have different levels, the requirements can be found through an employee to all employees of their subordinates, but also to their own superiors.Solution: Recursive implementation of infinite classification ideas, each employee to the parent's ID as their own PID, in addition to Path,path contains its own ID, convenient display path.Note Points for recursion:1. There must be a judgment condition, ot
Here is an easy way to create an infinite-polar classification tree structure. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting.
First on
Top class classification is actually a first-class classification, two-level classification is also called sub-classification classification, on this basis, sub-classification can also have sub-classification, which constitute
This article is a simple way to create an infinite-pole classification tree structure. Small series feel very good, now share to everyone, also for everyone to make a reference. Follow the small series together to see it, hope to help everyone.

This paper explains the method of realizing infinite class classification under the thinkphp Framework, which is commonly used in the classification menu of the website, is a very common data structure and function, and it is very easy to implement this method in thinkphp, then we will learn how to use it.
The principle of infinite classification is to add a field (such as SID) as a distinction, the top-le

This article summarizes the two PHP Unlimited class implementation program code, there is a need to learn friends can refer to.
Main idea: First look at the third row and the fourth row, the parent class ID (parentid) value is 1, representing the subclass belonging to the Id=1 class, whereas, one, 22 rows because it is a first class classification, there is no superior classification, so the parent class ID (parentid) value is 0, represents the primary classification, An
-comment as a sub-array of the parent comment, but as I write this can not be nested multi-layered comments, infinite pole nesting to do so?Thank you for asking for help!
Solution:
Is it possible to understand the problem of infinite classification?
Infinite class Classification $list = Array (' ID ' =>1, ' fid ' =>0, ' title ' = ' China '), array (' ID ' =>2, '
Function:
Infinite classification shows function get_str ($id = 0) { global $str; $sql = "Select Classid,classname,classstate,classtype,classurl,classpage,classorder,classtitle,classkeyword, Classdescription,classpid from Bz_class where classpid= $id "; $result = mysql_query ($sql);//The subclass of the query PID if ($result mysql_affected_rows ()) {//If there is a subclass while ($row = Mysql_fetch_array ($result)) {//cycl

Write recursive functions, you can consider caching, define some static variables to save the results of the last run, multi-program run efficiency is very helpful.The approximate steps are as follows :Step1: take data to a database, put it into an array,Step2: Converts the data into a tree-shaped array,step3: convert this tree-shaped array to HTML code.You can also combine the second and third ste
Always want to do the effect of circular slide slide, similar to PPTV, such as the home page effect is very sorry, not the whole GIF motion diagram ~ ~ ~Less nonsense, first look at the effect:The idea is: Set Pageradapter count as Integer.max_value, but the actual item only a few, with the way to take the remainder of the item, set the adapter at the same time set the CurrentItem to the actual item number n times ( Be big enough). This allows you to slide seamlessly around the loop! (After all,

Python multi-dimensional/nested Dictionary data infinite traversal implementation, python multi-dimensional
Recently I picked up Django and learned how to traverse multi-dimensional Dictionary data in the instance practice. Google does not query related information... After all, I was a newbie. When I started my work, I found that it was not just as simple as I thought. I had two twists and turns to achieve the effect. I recorded the process and hoped
If a function calls itself directly or indirectly, it forms a recursive (recursion), such as an implementation of the Fibonacci sequence.def fib (n): if n : return 1 else: return fib (n-1) + FIB (n-2)Recursion must have an end condition, otherwise a dead loop is formed, such as the following example:def A (): B ()def B (): if__name__'__main__ ' : A ()An exception will be thrown soon:runtimeerror:maximum recursion depth exceededWhat will be reported this anomaly, ve
