Select Box and Velocity
What is the recommended way of building select boxes with turbine and
velocity?
Is there an equivalent of the SelectorBox class that works with velocity
and a vector of Data objects?
Cheers,
Rich

Cool! Does anyone else have macros like this? It might be nice to
collect
all these HTML widget macros and collect them somewhere so that we
can all use them. I will collect them all and either put them in the
velocity CVS and make them available in the TDK for general use, or
keep them in Turbine CVS. We'll figure the storage out. But having
a widget library would be great!

this also belongs on the velocity list, not the turbine one.

you can either put some form of array (ArrayList, Vector, etc) in the
context and pass that into the macro, or you can create the options right in
your template like this...
#set ($myoptions = ["Choose Gender", "Male", "Female"] )
##and then call the macro
#generateSelectBox ( "gender" $myoptions 1 )

I've got velocity building select boxes -- that's no problem. What I'm
looking for is a convenience function for my template designers to use.
Say they are creating a form to edit a user record containing the user
name and their country.
The name part is easy:
Last Name: <input type="text" name="lastname" value="$user.LastName">
The country is much more difficult. I would like to pull a Vector of
countries (that has come via peers from a COUNTRY table in my database)
so they could do something like this:
#set ($countries = $countrytool.getCountries() )
Country: #selectBox( "country" $countries "CountryId" "CountryName"
$user.country )
## CountryId is the name of the property to use as the value and
CountryName is to be used as the label in the list
## $user.country is the user's current country that should be selected
by default
This would generate the <select> and <option> tags and stick <option
selected> next to the selected one. I don't think the template designer
should have to code a #foreach loop with a #if statement to place the
"selected" for something as common as a select box. If there's no such
function available I'd be happy to code one if someone could give me an
idea of the best way do this (as a velocity macro or toolbox?).
Cheers
Rich
ps i'm keeping this on turbine-user because the bit i'm having trouble
with is working with the data objects generated with Peers -- not the
VTL.

<select name=blah>
#foreach ( $book in $myBooks )
<option value="$book.ID">$book.Title
#end
</select>
assuming that myBooks is a Vector of book objects and that
the value is in book.getID() and shown option is book.getTitle()
remember that with velocity
book.ID will be expanded to book.getID()

Nathan,
Thanks that's a great start -- but how do you build your $options array
from a Vector of data objects? Say I've got a Vector of Book objects and
I want to build the select box from $book.getTitle()?
Cheers
Rich

try using a macro like this...
#macro ( generateSelectBox $name $options $selectedvalue)
<select name=$name>
#set ($count = 1)
#foreach( $option in $options )
#if ($selectedvalue)
<option value=$count #if ($count == $selectedvalue)
selected="1"#end>$option</option>
#else
<option value=$count>$option</option>
#end
#set ($count = $count + 1)
#end
</select>
#end
