[SOUND] Can you imagine if you visited Google and 0:00 you couldn't enter text for your search? 0:05 Or if you were using Facebook and you couldn't update your status or 0:10 comment on a friend's timeline? 0:14 Fortunately, for us and 0:16 the rest of the world HTMML forms make these features possible. 0:18 In fact it's difficult to use the web and not use HTML forms. 0:22 Hi, my name is James and I'm a developer. 0:28 In an earlier Treehouse course we were able to use ASP.NET MVC to 0:31 build an interesting website. 0:36 But our users couldn't interact with our content. 0:38 Meaning that they were unable to create, update or 0:41 delete any of the data that made up our websites content. 0:45 To give our users that ability our websites, 0:47 web applications or web apps need to include HTML forms. 0:51 HTML forms are made up of a combination of fields and buttons. 0:57 A field typically has a label and an input element. 1:01 Input elements come in a variety of types, including text boxes, 1:05 drop-down lists, radio buttons, check boxes and more. 1:09 Forms also include at least one button, typically a Submit or 1:16 Save button that when clicked sends the form data to the server to be processed. 1:20 When we combine a view that lists the available records, 1:26 along with views to create, update and 1:29 delete records, we're creating a type of application known as a CRUD application. 1:32 The acronym CRUD stands for Create, Read, Update and Delete. 1:37 CRUD applications or apps provide an end-to-end solution for 1:45 creating, reading, updating and deleting data. 1:50 Given how often users need to perform, 1:54 one or more of those actions on their data, CRUD apps are very common. 1:55 In this course, we'll be adding forms to an existing project, 2:01 to create a simple CRUD web app, that persists data to an in memory data store. 2:05 As we do that, we'll see how to use Razor to create forms. 2:10 We'll also learn how to update our controllers to handle form post data. 2:14 Use models with our forms and 2:19 leverage form validation to ensure that we get good or valid data from our users. 2:21 In a previous Treehouse course we learned about the in MVC design pattern, 2:28 URL routing, controllers, views, the Razor syntax and more. 2:32 These course will build upon those skills. 2:38 So if you haven't completed the prerequisites yet 2:41 be sure to follow the links in the teacher's notes. 2:44 Are you ready to start building your own forms using MVC? 2:47 Let's get started. 2:51
