Repeater (slice long list into 2)

[renobird]

I have a repeater that generates a list of links. The list could get pretty long (40+).

I'd like to break that up into 2 equal (or roughly equal) columns, but I can't get my head around how to do it with repeaters.

I'm trying this (which isn't working).

$p = $pages->get("/sponsors/");

$len = count($p->links);

$col_a = array_slice($p->links, 0, $len / 2);
$col_b = array_slice($p->links, $len / 2);

var_dump() for $col_a and $col_b returns NULL.

array_slice no good. Try $p->links->slice()

Actual array_slice isn't working because PageArray is not actually a php array, it's an object.

Hmm,

OK, tried that and got:

Recoverable Fatal Error Argument 1 passed to RepeaterPageArray::__construct() must be an instance of Page, none given, called in

$p = $pages->get("/sponsors/");
$len = count($p->links);
$col_a = $p->links->slice(0, $len / 2);

Ok, it might be that repeater has it's own RepeaterPageArray.

Not time to see source if there is slice available, but you can always loop through the links and put them into two different arrays.

OK, I'll try that route. Thanks Apeisa.

RepeaterPageArray extends PageArray so it should work.

That error is strange as if it tries to create new RepeaterPageArray and nothing to do with slice(start,end)...

Might be a bug.

I know it's not 'clean' but you could do it with this: http://www.madeincima.it/en/articles/resources-and-tools/easy-list-splitter-plugin/

Thanks Marty — I might go a JS route temporarily to get the site up, but now that I'm on this I really want to figure it out.

This is a bug. I'd actually fixed this one a week or two ago on the dev branch but hadn't carried it over to master. I just put it on master so it should be fixed now.
