Shortcode for the Formidable WordPress plugin, that returns the name of the current form (based on the entry ID).

form_name_shortcode.php

<?php
/*
 * Form Name Shortcode
 * For usage in confirmation email
 * Returns name of current form
 * Use the shortcode like this: [frm-form-name id=[id]]
 * The [id] parameter will produce the ID of current entry
 * See https://formidableforms.com/help-desk/using-form_name-shortcode-in-email-notification/
*/

function my_frm_name_shortcode( $atts ) {

	global $wpdb;
	
	$a = shortcode_atts( array(
			'id' => '',
		), $atts );
		
	if (!empty($a['id'])) {

		// get the Form ID, based on Entry ID
		$form_id = $wpdb->get_row( $wpdb->prepare(
			"
			SELECT form_id 
			FROM ". $wpdb->prefix ."frm_items 
			WHERE id = %d
			", 
			$a['id']) 
		);
		
		// get the Form name, based on Form ID
		$form_name = $wpdb->get_row( $wpdb->prepare(
			"
			SELECT name 
			FROM ". $wpdb->prefix ."frm_forms 
			WHERE id = %d
			", 
			$form_id->form_id ) 
		);
		
		return $form_name->name;
	
	}

}
add_shortcode( 'frm-form-name', 'my_frm_name_shortcode' );

Thanks for this... works perfectly!
