Shack Forms Pro allows you to validate that a forms submitter enters a proper email address into their form.

Here is how it works:

1. You make sure you selected the Email field type.
2. Shack Forms Pro will automatically add the validating RegEx code.
3. Save your form.

Let's take a look at this process in more detail.

• In your Joomla control panel, go to Extensions > Modules:

• You will see the Modules (Site) administrative page. Click on the required Shack Forms Pro module name to open it up for editing:

• Make sure you are viewing the Module tab:

• Scroll slightly down and click the Add new field button:

• You will see a new panel for creating a new field. Click Text:

• In the drop-down list of field types, click E-mail:

• You will see that along with the Field label and Alias name, Shack Forms Pro also populated the Validation (Regualar Expression) field with the #^[\w.-]+(\+[\w.-]+)*@\w+[\w.-]*?\.\w{2,}$# code. This code will ensure that your form submitters will enter their email addresses in a proper format:

• Click Yes for the Required parameter.
• Click Save or Save & Close.
