How to get "cursor" value to access "next" page and how to access nth page ?

[vishalmelmatti]

Hi,

$accountList = Recurly_AccountList::get($options);

I am fetching first page of accounts list by passing parameter per_page=10. I am getting Recurly_AccountList object.

As per your documentation, to access next page there is cursor parameter with "next" link.

I am trying to var_dump $accountList->getLinks() but it gives me empty array. I know there are hundreds of active accounts.

1 ) How do I get cursor value? I need to get this value so that it could be returned to my single page app which can in turn pass it to my backend to get next page ?

2. How do I get nth page ? lets say I want to access 7th page directly how should I access it ?

Thanks

Try:

$account_list = Recurly_AccountList::get(array('per_page' => 10));
$account_list->rewind();
var_dump($account_list->getLinks());

Frustratingly there's not a good way to jump all the way to the 7th page without fetching each intermediate page. The way the PHP pager (as opposed to the other clients) was designed, it hides the underlying pages exposing only the items in each page. Because the Pager is used as a base class for lists of items, rather than just using something simple like arrays, it's tightly coupled with the XML parsing. That makes it really hard to change it to expose pages of items in a way that's backwards compatible with current code :(

I'm wondering if the least bad thing to do would be to add a method to Recurly_Pager that was something like:

  public function nextPage() {
    if (empty($this->_links['next'])) {
      return false;
    }

    $this->_loadFrom($this->_links['next']);
    $this->_position = 0;

    return $this->valid();
  }

So you could do something like this to skip to a specific page and fetch its records:

$per_page = 10;
$page_number = 4;
$invoice_list = Recurly_InvoiceList::get(array('per_page' => $per_page));

// Advance to the desired page
$i = 0;
$invoice_list->rewind();
while (++$i < $page_number) {
  $invoice_list->nextPage()
}

// Extract the elements from the page.
$invoices = array();
$i = 0;
while ($i++ < $per_page && $invoice_list->valid()) {
  $invoices[] = $invoice_list->current();
  $invoice_list->next();
}

Thanks for the reply, will try this out.

It appears this was a question and that it has since been answered. @vishalmelmatti if you are still experiencing problems, feel free to continue the conversation or open another issue. The above advice is still the best way to get the nth page of results for the current version of the API.
