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 |
Use other field values in before and after
The before and after text can contain nested merge tags: write the merge tag with *| and |* instead of curly brackets.
{Street:3:gwp_append before="*|City:4|*, "}
