We must validate user input entered in forms to ensure data integrity and security. In our Anytown module, we need to verify that the location input for the weather forecast API is a valid 5-digit ZIP code.
In this tutorial, we'll:
- Add a
validateForm()method to the form controller. - Ensure the
locationfield contains a 5-digit ZIP code. - Display an error if validation fails.
By the end of this tutorial, you'll know how to add custom validation logic to a form.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
