frm_replace_shortcodes

This example can be used to add text or HTML below each field in your form.

add_filter('frm_replace_shortcodes', 'frm_change_my_html', 10, 3);
function frm_change_my_html($html, $field, $args){
  if($args['form']['id'] == 10){ //change 10 the id of the form to change
    $html .= 'add additional content here ';
  }
  return $html;
}

Use this example to take the radio or checkbox input OUT of the label tags. Please note: Conditional logic that uses radio or checkbox fields will NOT work when you use this code. You must use custom JavaScript to make other fields show or hide when a specific checkbox or radio button is selected.

add_filter('frm_replace_shortcodes', 'frm_change_my_html', 10, 3);
function frm_change_my_html($html, $field, $args){
	if ( in_array ( $field['type'], array( 'radio', 'checkbox' ) ) ) {
		$temp_array = explode('/>', $html);
		$new_html = '';
		foreach ( $temp_array as $key => $piece ) {
			// Get current for attribute
			if ( ( $pos = strpos( $piece, 'field_' . $field['field_key'] . '-' ) ) !== FALSE ) { 
			    $new_key = substr( $piece, $pos );
			    $key_parts = explode( '"', $new_key, 2);
			    $new_key = reset( $key_parts );
			} else {
			    $new_html .= $piece;
			    continue;
			}
			// Move opening label tag
			$label = '';
			$new_html .= str_replace( $label, '', $piece );
			$new_html .= '/>' . $label;
	  	}
	  $html = $new_html;
	}
  return $html;
}

Make this example specific to a field or fields by replacing this:

if ( in_array( $field['type'], array( 'checkbox', 'radio' ) ) ) {

with this:

if ( in_array( $field['id'], array( x, y, z ) ) ) {
