Hi,

I’d like to create a custom merge tag with modifier.

I’ve found and adapted a code to create a merge tag and it’s working well

Here’s my code :

add_filter('gform_custom_merge_tags', 'custom_merge_tags', 10, 4);
function custom_merge_tags( $merge_tags, $form_id, $fields, $element_id ) {
	$merge_tags[] = array('label' => 'conclusion', 'tag' => '{conclusion}');
    return $merge_tags;
}
add_filter( 'gform_replace_merge_tags', 'replace_conclusion', 10, 7 );
function replace_conclusion( $text, $form, $entry, $url_encode, $esc_html, $nl2br, $format ) {
 
    $custom_merge_tag = '{conclusion}';
 
    if ( strpos( $text, $custom_merge_tag ) === false ) {
        return $text;
    }
	$html = '<p><strong>some html</strong></p>';				
    $text = str_replace( $custom_merge_tag, $html, $text );
    return $text;
}

I’d like to add a modifier to add a variable in the variable $html.
Something like :

$html = '<p><strong>some html ' . $modifier . ' </strong></p>';

How to do that ?

Regards

To add a modifier to your custom merge tag, you can modify the replace_conclusion function to parse the modifier value from the merge tag and use it to construct the final HTML output.

Here is an updated version of your code with a modifier added:

add_filter('gform_custom_merge_tags', 'custom_merge_tags', 10, 4);

function custom_merge_tags( $merge_tags, $form_id, $fields, $element_id ) {
    $merge_tags[] = array('label' => 'conclusion', 'tag' => '{conclusion:modifier}');
    return $merge_tags;
}

add_filter( 'gform_replace_merge_tags', 'replace_conclusion', 10, 7 );

function replace_conclusion( $text, $form, $entry, $url_encode, $esc_html, $nl2br, $format ) {
    preg_match('/{conclusion:(.*?)}/', $text, $matches);
    if (empty($matches)) {
        return $text;
    }
    $modifier = $matches[1];
    $html = '<p><strong>some html ' . $modifier . '</strong></p>';           
    $text = str_replace( $matches[0], $html, $text );
    return $text;
}

In the custom_merge_tags function, we modified the tag to {conclusion:modifier} to indicate that this tag can take a modifier value. In the replace_conclusion function, we used the regular expression preg_match to extract the modifier value from the merge tag. This value was then used to generate the final HTML output.
