How to remove page prefix in paginated URL

[SoapyDaz]

TL;DR How to change a paginated URL so it reads "example.com/foo/2/" instead of "example.com/foo/page2/"?

Excuse me if this is the wrong place to post this (in which case please move this to the right forum), or this has been asked before... but how do you remove the "page" prefix in a paginated url so that it reads something like "example.com/foo/1/" instead of the default of "example.com/foo/page1/"?

I know that for any other type of prefix, I can just override $config->pageNumUrlPrefix in site/config.php, but I can't figure out how you'd do it if you simply want an effectively "blank" prefix. I've tried setting $config->pageNumUrlPrefix = '' but that ends up breaking pagination altogether or the page prefix ends up in the URL instead. The only way I can think of doing this is actually changing the line:

if(!$pageNumUrlPrefix) $pageNumUrlPrefix = 'page';

to

if(!$pageNumUrlPrefix) $pageNumUrlPrefix = '';

but tampering a module file seems bad practice and so I am looking for a better way to achieve this. Help a ProcessWire noob out!

Not having a prefix does currently break the detection of pagination urlSegments (see here), therefore it's not supported.

Maybe you can create your own pagination

$pageNumber = $sanitizer->selectorValue($input->urlSegment(2)); // wil get 2 from example.com/foo/2/

if(empty($pageNumber) || !is_numeric($pageNumber) || $pageNumber < 0) {
  $pageNumber = 0;
}

$limit = 10;
$base = "template=post";
$query = $base . ", start=" . (($pageNumber > 0) ? $pageNumber + $limit :  $pageNumber);
$query = $query . ", limit=$limit";

// template=post, start=0, limit=10                                       
$results = $pages->find($query);
  
$total = $pages->count($base);
  
$current = $pageNumber;
$next = $pageNumber++;

if($next > $total){
  $next = $total;
}
  
$prev = $pageNumber--;
if($prev < 0) {
	$prev = '';
}

Why no prefix?

I would rather use the Pager with a blank PageArray and trick it a little.

Configure your prefix to use something unique like "toreplaceprefix".

Set your template to allow page numbers AND url segments.

Then do something like this:

 

$limit = 2;
$start = $input->urlSegment1 ? ($input->urlSegment1 - 1) * $limit : 0;
$pageNum = $input->urlSegment1 ? : 1; // page number for pager

$pa = $pages->find("template=basic-page, start=$start, limit=$limit");

foreach($pa as $p){
    $content .= "<p>$p->title</p>";
}

$pagination = new PageArray();
$pagination->setTotal($pa->getTotal());
$pagination->setLimit($limit);
$pagination->setStart($pageNum);
$pagerHTML = $pagination->renderPager(array(
    "baseUrl" => $page->url,
    ));

$pagerHTML = str_replace("toreplaceprefix", "", $pagerHTML);
$content .= $pagerHTML;

Thank you to everyone who has responded - good to know that I haven't overlooked an option and rather it is because it is not officially supported!

@clsource: I'm guessing the first line of your code wouldn't work out of the box, if the URL to start with has the prefix "page" (or whatever I configured it to)? Or do I have to artificially create the URL such that it only says "/2/" (where 2 can be any page number)?

@Soma: Thank you for the code snippet - seems to work like a charm! The reason for no prefix is merely a cosmetic one rather than a functional one, so it's nice to know that it can be worked around even though it is not officially supported at the moment.

Tested the code snippet again more thoroughly and found that this line:

$pagination->setStart($pageNum);

causes the pagination to behave weirdly when I am on page 4+, changing it to:

$pagination->setStart($start);

seems to have fixed it. It looks like setStart takes the start offset rather than page number.

[Soma]

Thanks for the report. I was having trouble with it and it wouldn't work with the offset. I was wondering. Now that you mention it, maybe it has to do cause I used limit 2? I will have a look at it again cause maybe it's a bug.

[SoapyDaz]

@Soma I've tested it with bigger limits (like 5, 10 etc) and it still doesn't behave properly unless $start is passed to $pagination->setStart as I've suggested before.

Actually, just looked at the relevant documentation here and here's what it says:

Quote

PaginatedArray::setStart(int $numStart)

Set the starting offset number to use for pagination.

This is typically the current page number (minus 1) multiplied by limit setting.

which is exactly what your

$start = $input->urlSegment1 ? ($input->urlSegment1 - 1) * $limit : 0;

line does.
