rather than having a god awful long mess of "options" in the code, I would
like to populate the listbox by using php.

One short code I found winds up with an error.

Basically what I want is a simple array that holds a list of names.
A very long list. Over 500.
Actually, there will be 5 listboxes, with 100 to each box.

The idea being, that when a name is clicked on, which resides in one
division, the corresponding information will show up beside it in another
division.

Anyone have a site I can look at for help?
Googling just brings up tons of forums and sites that really don't discuss
what I need.

The populating of a listbox is pretty easy - just loop through the array
and echo the appropriate data, i.e.

foreach ($myArray as $myItem)
echo "<option value='$myItem'>$myItem</option>\n";

Of course, if you have a unique identifier for each item, that would go
in the value field instead of the item itself - but it gets the point
across.

If you want to display something based on the selection, you'll need a
client side language such as javascript; the best way to do it would be
to use AJAX to fetch the data from the server. See comp.lang.javascript
for more information on javascript and AJAX.

Something like this maybe

echo "<select name=\"pulldown1\">\n";
$i = count($options);
while ($i --) echo "<option value=\"$i\">{$options[$i]}</option>\n";
echo "</select>\n";

Not really sure what you're describing in the rest of your post though.

thanks jerry. your approach seems rather straightforward enough even for me
to understand. I hope.

So if I wanted to use a number after value= then I would use something like
value='number' ??

It depends on where you get the number from. You can't have just any
number - you need to associate that number to the value itself. For
instance, if the data were stored in a database, the value would often
be the unique id of that row.

Just quickly, I noticed both you and Jerry included \n (newline
character) in your output. Is there a specific reason for adding that?
Would have thought it was completely unnecessary.

Makes it a lot easier to read when viewing the source of the generated
webpage to see why it doesn't do what you want.

In this case, the OP is talking about 100 options in each list ....

If you were trying to debug that webpage, would you prefer:

<select name="somename" id="someid">
<option value="somevalue">sometext</option>
<option value="somevalue">sometext</option>
... repeat 98 more times 1 per line
</select>

or:

<select name="somename" id="someid"><option
value="somevalue">sometext</option><option
value="somevalue">sometext</option> .. repeat 98 more times on the same
line </select>

Unnecessary - but practical. Makes the source more readable when you
need to view it.

I would just like to add that you should pick one way of using
quotes. Single quotes are just fine in HTML. The example below is much
easier (readable) on the eyes in my opinion. Just keep in mind that \n
only works inside double quotes.

echo "<select name='pulldown1'>\n";
$i = count($options);
while ($i--) echo "<option value='$i'>{$options[$i]}</option>\n";
echo "</select>\n";

loadMenu.add("Legal Summons");
loadMenu.add("New Claims");
loadMenu.add("Potential Claims");
valueListBox.setValue(loadMenu.get(0));

What is your problem?

Did you ask GWT support? They know their code better than anyone else.
When having trouble with a product, generally the first place to ask
for help is in that product's support structure.

Admittedly I do not know much about GWT. But I do know that is *Java*-based,
that the code above looks like *Java* code, that it does not look anything
like (good) PHP code, and that by contrast this is a newsgroup where *PHP*
is on-topic.
