RE: Struts and Velocity Forms
Hi all, Continued working on this problem and have it resolved in the following Velocity macro. I'm surprised it didn't already exist being a very common requirement (maybe it does but I just haven't found it !!) --- #* * HTML velocimacro * @author Robin Mannering *# ## Checkbox control. 'Remembers' checkbox choices made by user on previous form submission. ## $name The control name ## $selectedValues A list of currently checked values ## $labels The list of labels for the options ## $values The list of values for the options #macro (checkboxGroup $name $selectedValues $labels $values) ## Use a zero-based counter. #set ( $index = 0 ) #foreach( $value in $values ) #set ( $rendered = false ) #foreach( $selectedValue in $selectedValues ) #if ( $value == $selectedValue ) input type=checkbox name=$name value=$value checked$!labels.get($index)/inputbr/ #set ( $rendered = true ) #end #end #if ( $rendered == false ) ## the current checkbox still hasn't been rendered it, so it must be rendered (unchecked) input type=checkbox name=$name value=$value$!labels.get($index)/inputbr/ #end #set ( $index = $index + 1 ) #end #end -- It can be used with the following example #set ( $interestLabels = [snowboarding, skiing, mountain biking] ) #set ( $interestValues = [snowboarding, skiing, mountain biking] ) #set ( $selected = $!newsletterForm.interestsDisplay ) #checkboxGroup ( interestsDisplay $selected $interestLabels $interestValues ) NB. $selected is a String[] in associated Struts form. -Original Message- From: Robin Mannering [mailto:[EMAIL PROTECTED] Sent: 23 March 2005 11:34 To: Velocity Users List Subject: Struts and Velocity Forms Hi all, Another newbie question here.

Re: Struts and Velocity Forms
What is being filled into the StrutsForm?
Is it something like:
public class MyForm
{
private String[] interestOptions;
public String[] getInterestOptions(){
return this.interestOptions;
}
public void setInterestOptions( String[] sValue ){
this.interestOptions = sValue;
}
}
And in your Action class you are making sure that interestOptions
are filled in? If so, you are actually blowing out the user's previous
selections by setting the array again. You've got to have a different
variable for the selectedInterests and the interestOptions. And then
you have to have a double #foreach loop looping through both arrays
(unless there is some way to get specific array values by index, which
I think there is but am not sure how to do it).
---
#set ( $index = 0 )
#set ( $interestOptions = [snowboarding, skiing, mountain biking] )
#foreach( $interest in $interestOptions )
#foreach( $selection in $selectedInterests )
input type=checkbox
name=interestsDisplay
value=$interest
#if( $selection == $interest ) selected #end$interest/input
#end
#set ( $index = $index + 1 )
#end
---
Or, if there is a way to get array values:
---
#set ( $index = 0 )
#set ( $interestOptions = [snowboarding, skiing, mountain biking] )
#foreach( $interest in $interestOptions )
input type=checkbox
name=interestsDisplay
value=$interest
#if( $selectedInterest.get($index) == $interest ) selected
#end$interest/input
#set ( $index = $index + 1 )
#end
---
Hope some of that helps.

RE: Struts and Velocity Forms
Hi Charlie,
Many thanks for that response...
I think we're both on the same train of thought here (with the nested loops).
The main difference I think is determining if the checkbox had been rendered on
each pass through the outer loop. The velocimacro I just submitted is the first
I've written so it's possible it could be tighter/shorter.
Can you break out of a velicity foreach loop? Could get rid of the 'rendered'
boolean then.
Thanks again for your input!
Robin
