Hello, it's the first time I write here and I'm a newbie at Zope, so maybe I'm asking a stupid question...
The only stupid question is the one that's never asked. You might, however, find that questions like this are more suited to the general zope@zope.org mailing list.
Case is I retrieve from my movie database the value of the movie from 1 to 5 stars. I would like to repeat that n times the code <img SRC="star.gif" height=15 width=15> so the number of stars would appear:
1 - * 2 - ** 3 - *** 4 - **** 5 - *****
Is there any way to do so in Zope? Does the <dtml-in> tag anything to do with it?
The <dtml-in> tag is certainly what you're looking for if you want to do this in DTML. Something like the following will do what you're looking for: <dtml-let stars="5"> <dtml-in "_.range(stars)"> <IMG SRC="star.gif" HEIGHT="15" WIDTH="15"> </dtml-in> </dtml-let> The <dtml-in "_.range(stars)"> ... </dtml-in> forms a loop that gets repeated 5 times by using the python range function -- generally, anything inside double quotes in DTML is treated as a python expression. You'll find that the "_." notation, which accesses the global namespace, allows you to make use of all sorts of python functions. You would replace the <dtml-let stars="5"> with a call to your database to find the actual number of stars. hth, -- Marcus
