cakephp : getting pagination link in json format - json

Question

I am developing a REST API using CakePHP and want to implement the Instagram API pagination style which looks something like this:
{
...
"pagination": {
"next_url": "https://api.instagram.com/v1/tags/puppy/media/recent?access_token=fb2e77d.47a0479900504cb3ab4a1f626d174d2d&max_id=13872296",
"next_max_id": "13872296"
}
}
I have not used any authorization or whatever, so the access_token part can be ignored. My main motive is to get the pagination links (jump links preferably) as JSON data, so I can use it in my JSON serialized view. Because the usual code:
echo $this->Paginator->prev('< ' . __('previous'), array(), null, array('class' => 'prev disabled'));
echo $this->Paginator->numbers(array('separator' => ''));
echo $this->Paginator->next(__('next') . ' >', array(), null, array('class' => 'next disabled'));
doesn't work and simply displays the equivalent HTML code.
Is there any way I can get it like the Instagram API?

Thanks to noslone, i have got the answer. here is the final edited code:
$url = 'http://yourapp.com/pages/index/limit:7';
$returnArray = array(
.....
'pagination' => array(
'next_url' => null,
'prev_url' => null
)
);
if($this->Paginator->hasNext()) {
$temp = intval($this->Paginator->current())+1;
$returnArray['pagination']['next_url'] = $url."/page:".$temp;
}
if($this->Paginator->hasPrev()) {
$temp = intval($this->Paginator->current())-1;
$returnArray['pagination']['next_url'] = $url."/page:".$temp;
}
echo json_encode($returnArray);
just two changes : first don't forget to add limit:value" to your url and secondly use intval with the Paginator->current.

Try something as follow
$url = 'http://yourapp.com/pages/index';
$returnArray = array(
.....
'pagination' => array(
'next_url' => null,
'prev_url' => null
)
);
if($this->Paginator->hasNext()) {
$returnArray['pagination']['next_url'] = $url.'/page:'. ($this->Paginator->current()+1);
}
if($this->Paginator->hasPrev()) {
$returnArray['pagination']['prev_url'] = $url.'/page:'. ($this->Paginator->current()-1);
}
echo json_encode($returnArray);
If you want, you can add more named params to the url:
$params['pagination']['next_url'] = $url.'/page:'.$this->Paginator->current()+1.'/order:name/direction:asc';

As far as I know, Paginator helper generates the front-end link, and when you click on it, it will generate next link.
I do not think you can use it directly to form the Instagram alike API.
