Quickstart

use Pop\Paginator\Paginator;

$paginator = Paginator::createRange(42); // Returns a Pop\Paginator\Range object
echo $paginator;

Which will produce this HTML:

<span>1</span>
<a href="/?page=2">2</a>
<a href="/?page=3">3</a>
<a href="/?page=4">4</a>
<a href="/?page=5">5</a>

And if you clicked on page 3, it would render:

<a href="/?page=1">1</a>
<a href="/?page=2">2</a>
<span>3</span>
<a href="/?page=4">4</a>
<a href="/?page=5">5</a>

Page Range

In the above example, a page range object renders a range of page links. With it, you can set a large number of pages and have it render "bookend" link before and after the range as the "previous" and "next" links. Pass the total number of items, the per page limit and the range limit:

use Pop\Paginator\Paginator;

$paginator = Paginator::createRange(4512, 10, 10); // Returns a Pop\Paginator\Range object
echo $paginator;

If we go to page 12, it would render:

<a href="/?page=1">&laquo;</a>
<a href="/?page=10">&lsaquo;</a>
<a href="/?page=11">11</a>
<span>12</span>
<a href="/?page=13">13</a>
<a href="/?page=14">14</a>
<a href="/?page=15">15</a>
<a href="/?page=16">16</a>
<a href="/?page=17">17</a>
<a href="/?page=18">18</a>
<a href="/?page=19">19</a>
<a href="/?page=20">20</a>
<a href="/?page=21">&rsaquo;</a>
<a href="/?page=452">&raquo;</a>

As you can see, it renders the "bookends" to navigate to the next set of pages, the previous set, the beginning or end of the set.

Page Form

To have a cleaner way of displaying a large set of pages, you can use the form object, which renders a input form field.

use Pop\Paginator\Form;
$paginator = new Form(558); // Returns a Pop\Paginator\Form object
echo $paginator;

This will produce:

<a href="/?page=1">&laquo;</a>
<a href="/?page=13">&lsaquo;</a>
<form action="/" method="get">
    <div><input type="text" name="page" size="2" value="14" /> of 56</div>
</form>
<a href="/?page=15">&rsaquo;</a>
<a href="/?page=56">&raquo;</a>

So instead of a set a links in between the bookends, there is a form input field that will allow the user to input a specific page to jump to.

Options

You can set many options to tailor the paginator object's look and functionality:

• Number of items per page
• Range of the page sets
• Separator between the page links
• Classes for the on/off page links
• Bookend characters
  • start
  • previous
  • next
  • end

use Pop\Paginator\Form;
$paginator = new Form(558); // Returns a Pop\Paginator\Form object
$paginator->setBookends([
    'start'    => '«',
    'previous' => '‹',
    'next'     => '›',
    'end'      => '»'
])

The start is the far left bookend that takes you back to the beginning. The previous is the left bookend that takes you to the previous page set. The next is the right bookend that takes you to the next page set. The end is the far right bookend that takes you all the way to the end.
