[Zope] Checkbox Help

[Tino Wildenhain]

Hi Todd,

as a service, Zope gives you a list if more then one
value of the same name exist in a form.

For what python types and especially lists are please
see http://www.python.org/ -> Documentation -> Tutorial

However, if you relie on this and get only one value,
its not a list. However there are posibilities to
cast an value explicitely to a list.

If you change your form like this:

<input type="checkbox" name="membership:list" value="D"> DMSO&nbsp;&nbsp;
<input type="checkbox" name="membership:list" value="A"> AMG&nbsp;&nbsp;
<input type="checkbox" name="membership:list" value="E"> EXCIMS&nbsp;&nbsp;
<input type="checkbox" name="membership:list" value="M"> MSWG&nbsp;&nbsp;<br>
<input type="checkbox" name="membership:list" value="V"> VV&amp;A TWG&nbsp;&nbsp;
<input type="checkbox" name="membership:list" value="T"> VV&amp;A TST&nbsp;&nbsp;
<input type="checkbox" name="membership:list" value="I"> MSTWG&nbsp;&nbsp;


You get always a list, no matter if there is one or any checkbox
checked. If there is no checkbox checked, you do not get anything at
all! So you might have to look for it (or use a default).

You should avoid using <dtml-var> in SQL Methods. Instead use
<dtml-sqlvar> since this quoutes correctly. Also <dtml-var ... sql_quote>
can be used. If you dont do so, you probably open a security hole.

Regards
Tino
