Tell us what you are trying to do?
I have to customs fields in a CRED form. Field B ('wpcf-rask-bis-tag') should have the same value like field A ('wpcf-rask-von-tag'), if the field is empty, when the CRED form is submitted
add_action('cred_before_save_data', 'func_assign_field_value',10,1);
function func_assign_field_value($form_data)
{
// if a specific form
$forms = array( 5629 , 10440 , 10362 );
if (in_array($form_data['id'], $forms))
{
if (isset($_POST['wpcf-rask-bis-tag'])) {
$_POST['wpcf-rask-bis-tag'] = $_POST['wpcf-rask-von-tag'];
}
}
}
What is the problem?
Now Field B has always the value of Field A - no matter if it was empty previously or not ..
Is there any documentation that you are following?
Yes, there was a documentation, but I can't find it anymore.
Is there a similar example that we can see?
In the documenatation, that I lost

Hi,
Thank you for contacting us and I'd be happy to assist.
If your goal is to make "wpcf-rask-bis-tag" field use the same value as the "wpcf-rask-von-tag" field, only when "wpcf-rask-bis-tag" field's own value is empty, you can adjust your code to:
add_action('cred_before_save_data', 'func_assign_field_value',10,1);
function func_assign_field_value($form_data)
{
// if a specific form
$forms = array( 5629 , 10440 , 10362 );
if (in_array($form_data['id'], $forms))
{
// if value of wpcf-rask-bis-tag field is empty
if (empty($_POST['wpcf-rask-bis-tag'])) {
// make wpcf-rask-bis-tag field use the same value as the wpcf-rask-von-tag field
$_POST['wpcf-rask-bis-tag'] = $_POST['wpcf-rask-von-tag'];
}
}
}
I hope this helps and please let me know if you need any further assistance around this.

Thanks Waqar! Now it works perfectly.
Using empty instead of isset solved the problem 🙂
I try to re-open. I didn't test properly. Today a beta-tester pointed out that it still doesn't work.
The wpcf-rask-bis-tag is a datepicker field. Is it possible, that it is not empty by default? I mean, even before the user set a date?
