Tell us what you are trying to do?

I am trying to save user IP address while he submits form.

Added shortcode in functions.php

add_shortcode('get_client_ip', 'get_client_ip');

function get_client_ip() {
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}

and it works, my IP address is noted. Then created generic field:

[cred_generic_field field='ip-address' type='hidden' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":"[get_client_ip]"
}
[/cred_generic_field]

ip-address is slug for custom field created by toolset and after that in same php file I aded this function:

add_action('cred_save_data', 'save_ip_address',10,2);
function save_ip_address($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==236)
{
if (isset($_POST['ip-address']))
{
// add it to saved post meta
add_post_meta($post_id, 'wpcf-ip-address', $_POST['ip-address'], true);
}
}
}

ID for CRED form is 236 and slug for custom field id is wpcf-ip-address. What I failed to understand is if I am correct with ip-address parameter here $_POST['ip-address']

Is there any documentation that you are following?

Saw this:
https://toolset.com/forums/topic/ip-address-with-registration-from/

Is there a similar example that we can see?

I don't know

Hello,

In your case, the [cred_generic_field] is not needed, I suggest you remove the [cred_generic_field], and modify your PHP codes as below:

add_action('cred_save_data', 'save_ip_address',10,2);
function save_ip_address($post_id, $form_data)
{
// if a specific form
	if ($form_data['id']==236)
	{
		$ip = $_SERVER['REMOTE_ADDR'];
		//The IP address from which the user is viewing the current page. 

		update_post_meta($post_id, 'wpcf-ip-address', $ip);
		//Update post meta field
	}
}

It works. If I want multiple forms to be included I just need to modify if statement. Thanks a lot.
