How to Create Input Masks for Your Site’s Forms (with Examples)

Want to learn how to create input masks for your site’s forms? Being able to customize the way data is entered into your WordPress forms makes the user experience easier and ensures that the right data in entered into your form every time.

In this article, we’ll explain to you what an input mask is and show you how to add them to your site’s forms.

What Is an Input Mask?

Input masks are a way to control what data can be entered into a form’s field. They are governed by a strict set of rules that site visitors can’t break while trying to fill out your form.

The rules for custom input masks include the following symbols:

• 9: Numeric (0-9)
• a: Alphabetical (a-z or A-Z)
• A: Uppercase alphabetical (A-Z)
• *: Alphanumeric (0-9, a-z, or A-Z)
• &: Uppercase alphanumeric (0-9 or A-Z)

Simply use the above-mentioned symbols in your input masks to correspond with the data you want entered into your form field.

When a site visitor clicks on a form field that has a custom input mask, they’ll see an underscore for each required digit or letter that’s required. This helps guide the site visitor as they fill out your form and help boost conversions.

You can also add things like hyphens or parenthesis in your input mask. This is especially helpful when you want people to fill out their phone number on your site’s form.

If you want to add any additional characters, after already using the parenthesis, you should place them in brackets. This is good for times when the additional characters are optional.

Input Mask Examples

Now that you know what an input mask is, it’s time to take a look at some of the most basic examples you can use in your WordPress forms.

United States Zip Code:

• Mask: 99999
• Example User Input: 89023

United States Zip Code with Optional Plus Four:

• Mask: 99999 [-9999]
• Example User Input: 89023 or 89023-5678

• Mask: Aaaaaa [aa]
• Example User Input: Minnie or Minniems
