Docs » Advanced Merge Tags » gwp_append

With the gwp_append Merge Tag Modifier for Gravity Forms you can append a string before and/or after the field value, but only if the field value is not empty.

:gwp_append before="" after=""

If you want to change the output of a Merge Tag text, use the Modifier like this:

Example	Modifier	Output	Info
{Example:1}		WP	Value of the field is ‘WP’
{Example:1:gwp_append before="Gravity" after=" is great"}	:gwp_append before="Gravity" after=" is great"	GravityWP is great	Modifier adds ‘Gravity’ before and ‘ is great’ after the value ‘WP’
{Example:2} (empty field value)			Value is empty
{Example:2:gwp_append before="Gravity" after=" is great"}	:gwp_append before="Gravity" after=" is great"		Modifier doesn’t append, because the value is empty

Frequently Asked Questions about gwp_append

What does the gwp_append modifier do?

The gwp_append modifier allows you to add custom text before and/or after the value of a field in Gravity Forms. This text will only appear if the field has a value. If the field is empty, no output is shown.

You can use this modifier in confirmation messages, notification emails, or any other place where merge tags are supported.

Example:

{First Name:1:gwp_append before="Hello " after=", welcome!"}

If the user enters:

Jon

The output will be:

Hello Jon, welcome!

What happens if the field is empty?

If the field is empty, gwp_append does not display anything — neither the before nor after text will be shown.

Example:

{Company:2:gwp_append before="Company: " after=" Ltd."}

If Company is empty → no output.

Can I use only before or only after?

Yes, you can use only before=”…”, only after=”…”, or both together.

Example — only after:

{Age:3:gwp_append after=" years old"}

If user enters 25 → shows:

25 years old

Can I use special characters or emojis with gwp_append?

Yes. You can include special characters, punctuation, or emojis in the before or after text.

Example:

{Name:1:gwp_append before="🎉 " after=" is awesome! 🚀"}

If user enters Jon → shows:

🎉 Jon is awesome! 🚀

Where can I use gwp_append?

You can use it in any part of Gravity Forms that supports merge tags, such as:

• Confirmation messages
  
• Notification emails
  
• HTML fields in forms or pages
  
• GravityView templates (if merge tags are supported there)

Example in a confirmation message:

{First Name:1:gwp_append before="Hello " after=", welcome to our site!"}

First Name = Field label
1 = Field ID
gwp_append = merge tag modifier
