They are treated in the same way as a letter. DTML restricts the use of "_": A name must not *START* with an "_" (unless it is the special name "_"). Inside name, you can use "_" freely. > > dats it.

Use: I.e. you can simply use the name of the variable. Manuel is right, too, that DTML allows much more characters in names than Python does. If you have a name with a character forbidden in Python names, such as e.g. a "-", then you can use "_[name]" or "_.getitem(name)" (as Manuel said). It is only, that "_" (unlike "-") is allowed in Python names.

[Zope] sql query results -> DTML method problem
Hi, I have a TINY problem, which I think there is a simple solution too... but for the life of me, I can't find it! I'd be grateful if someone could point me in the right direction. I have a database setup containing details of classes, students & lecturers. The user is prompted to enter a class code (a unique key) which is used to query the database and return the class title. Simple. A DTML method prompts me for the class code -- I enter 52.139 and it posts to a method 'enterClassCodeAction', below. #1 #2 Confirm #3 You entered #4 #5 #6 Our records show that is called #7 #8 #9 #10 #11 #12 #13 #14 ^ The method works fine when the class code is manually inserted (line #8) but when I try to pass the variable from the previou post, held in I have probs. *** syntax error findClassTitle is a ZSQL method for returning the class title given a class code: select title from classes where Hmm... anyone see the problem? Thanks a lot :) - Best regards, Lee ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
