nuMessage() / PHP

Hi,
I'd like to display a message with PHP. I thought I could call
in the AS event, but the passed parameter o is empty. What am I doing wrong?

toms,
If you want to set a message with
Javascript (which takes an
Array of Strings) use...
Code: Select all
nuMessage(['Hello World']) - which takes an Array of Strings.
If you want to set a Message with
PHP (which takes a String) use...
Code: Select all
nuDisplayError('Hello World'); - which takes a String.
If nuDisplayError() is called in the Before Save or Before Delete, it will stop the record being Saved or Deleted.
Otherwise, it will just return a message...

Steven,
Actually I just want to show an info message in PHP, nuDisplayError() is not suitable since it will then not save the record.
I was wondering why I could call the js function nuMessage() from php (but, as already mentioned, no parameter is passed).

toms,
If nuDisplayError() is used in After Save or After Delete, a message will now appear.
Please see if this now works for you.
(You'll need the latest from Github.)

Steven,
It works all fine. I just think that the function's name is a bit misleading since, in this case, it shows only an ordinary message and not an error message.
Just as an idea for the (far) future : A function nuDisplayMessage() could be created with different types of messages.
Something like that:

toms,
Hopefully, nuDisplayError() isn't so confusing to the developer if they read the wiki.
http://wiki.nubuilder.net/nubuilderfort ... splayError - I updated it yesterday.
If you mean a message might be misleading to a User, then that could be considered the developer's fault.
But the string passed to nuDisplayError can be HTML.
So you could do something like this...
Code: Select all
nuMessage(["<img id='nulogo' width='40px' src='graphics/numessage.png' style='position:absolute;left:2px;top:2px'>","That is now finished!"])
and
nuerror.png are available in nuBuilder Forte's graphics directory.

I mean if nuDisplayError() is not always intended to display an
error message, then the name is misleading. But that's a matter of opinion.
While nuMessage() can be used in Javascript,
I just want to show an info message in PHP
Is there an easy way to call nuMessage() from PHP code? I've tried using echo but without success.

I don't understand your question.

nuMessage() is a Javacript function.

My question was:

A possible solution to use nuMessage() in PHP:
Code: Select all
$j = "nuMessage([\"<img id=\'nulogo\' width=\'40px\' src=\'graphics\/numessage.png\' style=\'position:absolute;left:2px;top:2px\'>\",\"That is now finished!\"])";
nuAddJavascript($j);
: The message is not showing up in AS (PHP)

toms,
nuAddJavascript() adds Javascript to a Browse Form or an Edit Form as it loads the Form.
It will only work with
Before Save and
Before Edit.
