Hello!
According to
https://wiki.nubuilder.cloud/index.php?title=Functions PHP BeforeSave event can stop saving process by value "No" (as on scheme). What and how PHP code should return for "YES" and "NO' values. I can't find any example in docs.

Hi,
The diagram you are referring to only illustrates the possible paths that the "BeforeSave" event can take (continue saving or abort saving).
You can use the
nuDisplayError() function to display an error message to the user to abort saving and display a message.
Example:
Code: Select all
// Some validation code to check if the data is valid
if (/* data is not valid */) {
// Display an error message and stop the save process
nuDisplayError('The data you entered is not valid.');
} else {
// Allow the save to continue...
}

One approach that comes to mind is to promptly remove the message by declaring nuOnMessage() in the form's Custom Code:
Code: Select all
function nuOnMessage(msgDiv, errors) {
if (errors == 'do_not_show_the_error') {
msgDiv.remove();
nuAbortSave();
}
}
And in BS
Code: Select all
nuDisplayError('do_not_show_the_error');
