[Zope-dev] I read your tip about "Multiple Selections" but i need more details:

25 Jul 2001

      select ... where
     col in ( <dtml-var "_.string.join(multiple_selection,',')"> )

Can you make a full example of this, PLEASE ?

Because i don´t know where to put this code !

Musi i put it all in a ZSQL-Method and if how will look this query:

Here my query:

select ap_selection from Projects where proj_id=<dtml-sqlvar proj_id
type=int>

Comment:
ap_selection is the coloumn where the selected values are stored like this:

[value1,value2,value3,...] (It is a MS SQL Server2000)

****************************************************************************
Can you have a this ?
****************************************************************************
<dtml-call "REQUEST.set('selectedAP',[])">
<dtml-in List_SelectedALIASPAGES>
  <dtml-call "selectedAP.append(proj_id)">
</dtml-in>

<dtml-in List_ALIASPAGES2>
      <input type=checkbox name=ap_selection:list value="<dtml-var
sequence-item>"
		<dtml-call expr="REQUEST.set(selectedAP,_['sequence-item'])">
		<dtml-in List_SelectedALIASPAGES>
			<dtml-if expr="_['sequence-item'] == selectedAP">
				checked
			</dtml-if>>
		</dtml-in>
      <dtml-var sequence-item><br>
</dtml-in>

***************************************************************************
This ERROR comes:
