html tag calculation

Classic Servoy
1

Hi
Any chance you can help with this one?
Jan recently showed us how to use a calculation to add html tags either side of a shippet of html content stored in a database, so that we can display the html in a servoy client.

But I don’t seem to be getting the code right?

return “”%htmltext%“”;

“htmltext” is the name of our column containing the html code with out html tags. Eg:

Test content

The problem seems to be that the “htmltext” does not concatonate..
All that displays in the client is: NaN

I’ve tried
return “”%htmltext%“”;
return “”%%htmltext%%“”;
And many more variations.. Can you see where we are going wrong?

Many thanks
Eugene

try this:

return “” + htmltext + “”;

also look in de CRM demo, You see a lot of examples there!

Eugene, you should set it to:

return "<html>%%htmltext%%</html>";

your column should hold the tags in the following format:

"<h1 class='style2'>Test content </h1>"
```.

You have to use hanging comma's within the string to get it right.

Remember to tick the displayTags property of the column that shows the html.

do you know if this method is the best one to use to mail merge into the parth of an image in order to construct a url from different parts of a database?

thanks Marcel..
this is more of less what i meant
return “<img src='URL.com - MediaOptions”+ id + “/photo1.jpg’”;

this seems to work but is probably not the best way to do it..? :roll:
thanks

Well, it is a very fine way if you want to show that image depending on the content of the current record (or whatever)…
