When any validation checks returned true, we can set the error with a message into the ModelSate object. Execute("INSERT INTO articles (title, summary, body, record_date) " summary, body, record_date) ModelState.AddError("Body","Please write something in the body (IsPost & ModelState.IsValid) ModelState.AddError("Summary", "You can't put the article summary empty") ModelState.AddError("Title", "Post title can't be empty") We can use these helper functions in this project. These functions are: IsBool(), IsDateTime(), IsDecimal(), IsFloat(), and IsInt(). Also there we have functions where we can check if they are in a certain condition. The AsBool(), AsDateTime(), AsDecimal(), AsFloat(), and AsInt() functions are used to convert the current data type to (AS) new type. In Razor, there are multiple helper functions which will help do validation in form operations. Validation can be as simple as requiring that a form field not be empty, that the field be a certain type, or that a value fall within a particular range. Validation is an important and vital part of form and data process in web platforms. title = Request Īfter getting the posted data into variables and after checking that if they are really coming from a post request, we can start writing our SQL queries to insert these data into database. In this project, we submit it back to the page itself and will extract the data posted from request object to variables and will query an insert query to save it.
We used the POST method to submit the page data. As you may already know, in order to get and save some information as an input, we generally use a form.
