Do you know you can add functionality to your Gravity Forms Merge Tags. This can come in handy, for example when you want to show a field input capitalized or you want to replace certain values in the field.
Merge Tag Modifier Gravity Forms
Create a Merge Tag modifier for uppercase
Take for example that you want to show a certain Merge Tag value in capital letters. A simple way to do that is to add a Gravity Forms Merge Tag modifier to your functions.php.
add_filter( 'gform_merge_tag_filter', function ( $value, $merge_tag, $modifier, $field, $raw_value ) {
if ( $merge_tag != 'all_fields' && $modifier == 'gwp_uppercase' ) {
$value = strtoupper ( $value );
}
return $value;
}, 10, 5 );You can see we do different things in the PHP code:
- add a filter to the gform_merge_tag_filter hook
- check if it's not used in the all_fields Merge Tag from Gravity Forms (since this is a unique merge tag to output all the data in a table, we don't want to attach our modifier to that one)
- check if the modifier is gwp_uppercase
- do something with the value that is passed (this is the value that the visitor filled in in the specific field you refer to with the modifier)
- in our case: we use the PHP standard function strtoupper to make all the letters uppercase
