nuBuilder Forum

On the form, using php, I make a request to the database 1. If the data is received, I write it to another database 2. Using js, I fill the table from
database 2 on the same form, save the form and update with nuGetBreadcrumb() on the ssame button with php-procedure.
Task: If data is not received, display a message for the user.
Problem:
nuDisplayError displays a message for a very short time because nuGetBreadcrumb() fires.
nuJavascriptCallback() does not display this message at all for the same reason.
How to make a delay before nuGetBreadcrumb() in case of an empty database request.

Hi,

Use JS setTimeout()

Where to place this code?
On my button, it's already implemented like this:
onclick - nuRunPHPHidden('DB'); nuGetBreadcrumb(); nuMessage(['Wait...']);
onclick - getCurrentTime('#konv_vr');

nuRunPHPHidden() is executed asynchronous, that means nuGetBreadcrumb(); is usually called before nuRunPHPHidden() has finished executing.

The way to go is to run nuRunPHPHidden() and call nuJavascriptCallback() within the PHP code that executes nuGetBreadcrumb(); etc,

Unfortunately the code does not work as expected.
The visibility of nuMessage and nuDisplayError is very low to read the message.
As an alternative, I applied alert via nuJavascriptCallback.

Do you need to call nuGetBreadcrumb() at any case, if there is an error or not?

nuGetBreadcrumb() in any case, it must be applied, because i need to save the time of button click. It could be that nuSaveAction() applied on the same button prevents the nuMessage from being displayed for a long time. It does not give errors according to your code, but as I said, the message display is very short.

I tested it with this Procedure and the message is shown for 3 seconds before the form is refreshed.

Hi,

Were you able to solve this?

Your code works... but I've decided that alert() is preferable to ensure that the user is informed.
Thanks !
