Glob pagination rewrite url - php

Question

Update
Tested my script outside Wordpress and it works. So the problem with this pagination is inside Wordpress. I did some research and I added this rewrite code to my functions file, but still it doesn't work
function my_rewrite_globe_pagination()
{
add_rewrite_rule('^newspaper/page/([0-9]{1,})/?', 'index.php?paged=$matches[1]', 'top');
}
add_action('init', 'my_rewrite_globe_pagination');
The next button url looks like this: domain/page-name/?page=2
URL in browser after clicking next: domain/page-name/page/2/
Before update
first of all I would like to say I read all the similar questions on stackoverflow but I din't find the solution fitting to my case.
What I'm trying to achieve is a globe numeric pagination at my wordpress page. In my page template I have the code listed below and I have with this code two problems:
one is that I don't know how to change the prev and next buttons to numeric pagination
second whenever I click on the next button I see the same two images as on first page, despite the fact that my url changes to domain/page-name/2/
if (isset($_GET['page'])) {
$page = $_GET['page'];
} else {
$page = 1;
}
$base_dir = trailingslashit(wp_upload_dir()['basedir']);
$base_url = wp_upload_dir()['baseurl'];
$dir_jpg = '/newspaper/jpg/';
$dir_pdf = '/newspaper/pdf/';
$images = glob($base_dir.$dir_jpg.'*.*');
$limit = 2;
$total =count($images);
$total_pages = ceil($total/$limit);
$offset = ($page-1) * $limit;
$images = array_slice($images, $limit);
foreach($images as $image) {
$url = $base_url.$dir_jpg.basename($image);
$filename = substr(basename($image), 0, -4);
$pdfs = $base_url.$dir_pdf.$filename.".pdf";
printf('<img src="%s" alt="'.$filename.'.pdf"><div class="newspaper-hover"></div>', esc_url($url));
}
?>
<ul class="pagination">
<li class="<?php if($page <= 1){ echo 'disabled'; } ?>">
Prev
</li>
<li class="<?php if($page >= $total_pages){ echo 'disabled'; } ?>">
Next
</li>
</ul>

Answer 1

For the first problem you simply have to print $page - 1 and $page + 1 instead "Prev" and "Next" (and check if the current page is the first or the last):
<ul class="pagination">
<li class="<?php if($page <= 1){ echo 'disabled'; } ?>">
<?php echo ($page <= 1) ? "X" : ($page - 1)?>
</li>
<li class="<?php if($page >= $total_pages){ echo 'disabled'; } ?>">
<?php echo ($page >= $total_pages) ? "X" : ($page + 1)?>
</li>
</ul>
The second problem is caused by your incorrect call to array_slice.
According to the documentation, the second parameter must be the start offset of the array ($offset in your case) and the third the length of the array you want ($limit), so this should fix it:
$images = array_slice($images, $offset, $limit);
