Alphabetically display DataObjects
17 November 2010 at 10:30pm
I know there's been some discussion about this in the past, there's even a recipe about this issue but i just don't get it to work.
I have a lot of Movies (about 200+) and TV Series (about 180+) they're both DataObjects.
I used the tutorials
" http://ssbits.com/tutorials/2010/dataobjects-as-pages-part-1-keeping-it-simple/ "
to make everything work as i need but my sidemenu is getting waaaaay to long.I need to sort them out in some kind of ABC, so i don't want the whole listing in the sidebar. I want to have some kind of Navbar on top of my page witch will show [ 0 - 9 | A - C | D - F etc. ] and then when i select one of those it will show only those movies.
Now i've been through the recipe http://doc.silverstripe.org/recipes:alphabetical_dataobjectset but i don't get it to work.
I could really use an (extended) example.
Tx in advance

That's super easy..
static $ranges = array (
'0-9',
'A-D',
'E-G',
// etc...
);public function AlphaLinks() {
$set = new DataObjectSet();
foreach(self::$ranges as $range) {
$set->push(new ArrayData(array(
'Link' => HTTP::setGetVar('range', $range),
'Current' => $this->getRequest()->getVar('range') == $range,
'Label' => $range
)));
}
return $set;
}public function AlphabeticalItems() {
$r = $this->getRequest()->getVar('range');
if(!$r) {
// default range to show
$r = "A-D";
}
list($start, $end) = explode("-", $r);
return DataObject::get("SomeDataObject", "Title > '$start' AND Title < '$end'");
}template
<% control AlphaLinks %>
<a href="$Link" <% if Current %>class="current"<% end_if %>>$Label</a>
<% end_control %><% control AlphabeticalItems %>
$Title
<% end_control %>Can't promise it's free of parse errors, but that should get you started..

Wauw UC,
That sure gives me a great deal of what i was looking for. The only thing is that its giving me the ID instead of the name of the Serie ( SerieName in my case ).
Could you help me out with that also please?
tx
btw; i figured out the exploding thing .

Ha.. I wrote "that's super easy" before I actually coded all that up. Agreed, it's not super easy, but it's really not a huge undertaking in the grand scheme of things.
Quick PHP lesson:
explode() is a function that breaks a string up into an array when given a certain delimiter. It's Javascript counterpart is split(), if you've ever used that.
$str = "One/Two/Three/Four";
var_dump(explode("/", $str));// returns:
array (
'One', 'Two', 'Three', 'Four'
)list() is a weird function that takes all the members of an array and makes them their own variables..
list($one, $two, $three, $four) = explode("/", $str);
echo $two;
// returns "Two"
So in my example, you're exploding "A-D" to be an array of "A" and "D"
list($start, $end) will give you:echo $start; // "A";
echo $end; // "D";Make sense?

What do you mean "it's giving me the ID".. where? On the template?
If you don't have a "Title" field, replace that with whatever you're using as a label.

UncleCheese,
Do you get payed for all your advice? My God this must be the best support forum i have ever encountered.
Anyway,
on my frontend it shows the 0-9, a-d etc. links, but when i click on one of them it returns the ID of the corresponding DataObjects.
I did change
<Code> return DataObject::get("SomeDataObject", "Title > '$start' AND Title< '$end'"); </Code>
to
<Code> return DataObject::get("Serie", "SerieName > '$start' AND SerieName < '$end'"); </Code>
