Simple PHP form validation: Form validation is a most important for a developer. Below example show a simple form validation. Below I create a simple form. Inside this form create a simple table. Inside this table I create table row and table data field. Inside the table data field I take three input field and one submit button. I give three input fields name is username, email and websiteurl. Now start validation process. At first I catch the all input field via super global variable $_POST and store this inputs field data three different variables like - $username, $email and $websiteurl then I throw two message like error message and success message. That sits. If a user does not field user name field and click the user login button then show error message like – “User name field does not be empty”. A user fill up all input field and click the user login button then show a success message like – “User login successfully”. Enjoy this form and apply your website.
