nuMessage() / PHP Topic is solved

[toms]

Hi,

I'd like to display a message with PHP. I thought I could call

Code: Select all

nuMessage("Hello"); 

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.

http://wiki.nubuilder.net/nubuilderfort ... splayError

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).

[admin]

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!"])

numessage.png and nuerror.png are available in nuBuilder Forte's graphics directory.

opefully, nuDisplayError() isn't so confusing to the developer if they read the wiki.

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.

toms,

I don't understand your question.

Is there an easy way to call nuMessage() from PHP code?

nuMessage() is a Javacript function.

My question was:

Is there an easy way to call nuMessage() from PHP code? I've tried using echo but without success.

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);

EDIT: The message is not showing up in AS (PHP)

[admin]

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.
