From Zhang Ziyang http://www.cnblogs.com/JimmyZhang/archive/2009/05/18/1459330.html The purpose of this tutorial is to explain an ASP. net mvc application.ProgramCreate a model class. In this tutorial, you will learn how to use Microsoft LINQ to SQL to create model classes and perform database access. In this tutorial, we created a basic movie database application. We try our best to

programming. What is the use of the ThinkPHP: create () method? 1. the create method can process the data submitted by POST (the data instance is automatically encapsulated by the correspondence between the field name in the table and the name submitted by the form).

object of this anonymous inner class. Because the anonymous inner class has no name, So it is not possible to initialize through constructors, we can achieve the effect of constructors by initializing blocks (we can, of course, call the constructor of the base class to initialize the member variables of the base class

create a data object, form verification is automatically performed at the same time. if you do not use this method, you need to manually call the autoCheckToken method of the model for form verification. If (! $ User-> autoCheckToken ($ _ POST) {// token verification error} I hope the examples shown in this article will be helpful for ThinkPHP programming. What is the use of the ThinkPHP: create () meth
