In this blog post I will tell you how to use the Number of characters validation option.

This option has three parameters (Is, Minimum, Maximum).

We'll take an example form "Leave you comment/opinion/feedback".

1. Create new project "Validation"
2. Add "Comments" field  with a Multiple Line type to a new form "Example form".  Open field for Editing and at the bottom you'll see 'Validation' link.
3. Click on "Validation" link and select options you needumber of characters your users will need to enter or minimum/maximum values. 
 

Once edited you can test it and you'll see errors if someone entered more then 10 characters.

So, you know how easy it is to create a simple database with QuintaDB.

You can embed this form into any web site using Form menu under 'Widgets' section.
