Re[2]: [Zope] absent variables

[Miha]

Hello Thomas,

Your words are right, but that isn't context depended problem. Here I
can find simple solution, but in other keys? Big thanks for you
attention.

Subject: [Zope] absent variables
TBP> You have two things to deal with.

TBP> 1) You are using a checkbox for the "favorite" input element.  When a
TBP> checkbox is not checked, it does not return a variable of that name in the
TBP> form.

TBP> 2) You have more than one checkbox with the name "favorite".  If more than
TBP> one are checked, the form will return a list containing all the values.
TBP> Furthermore, if only one is checked, the form will return a single string,
TBP> not a list.  This would require further testing and handling.  You can make
TBP> the form always return a list by changing the name of the input to
TBP> "favorite:list".  You would still refer to the variable as "favorite".

TBP> Both possiblities will cause errors for your insert statement.

TBP> First, you need to decide whether you really want to allow more than one
TBP> "favorite" value.  If you do, you need to figure out how they should be
TBP> represented in the database.  Then you need to loop through the values.

TBP> If you decide you only want one value, you can change to using radio
TBP> buttons.  One button could have the value '' (the empty string), and the
TBP> lable "No Favorite".  This way, you would always get a single string in the
TBP> form data, although it might be an empty string.  Your insert code would
TBP> work correctly.
