Problem with URL segments (when a number)

[SamC]

So I've been working with categories: 

...and advancing upon this as a way to get to learn URL segments. So mysite.com/cars/ outputs all cars:

...with the code being:
 

// car-index.php
<?php namespace ProcessWire; ?>

<?php if($input->urlSegment1) {
    $segment1 = $sanitizer->pageName($input->urlSegment1);
    echo $segment1;
    }
?>

<?php if($input->urlSegment2) {
    $segment2 = $sanitizer->pageName($input->urlSegment2);
    echo $segment2;
    }
?>

<h1>Index of cars</h1>

<?php

$cars = $pages->find("template=car-entry," . $segment1 . "=" . $segment2);

foreach ($cars as $car): ?>

<h2><?php echo $car->title; ?></h2>

<p>MAKE: <a href="/cars/make/<?php echo $car->make->name; ?>"><?php echo $car->make->title; ?></a></p>
<p>MODEL: <a href="/cars/model/<?php echo $car->model->name; ?>"><?php echo $car->model->title; ?></a></p>
<p>YEAR: <a href="/cars/year/<?php echo $car->year->name; ?>"><?php echo $car->year->title; ?></a></p>
<p>COLOUR: <a href="/cars/colour/<?php echo $car->colour->name; ?>"><?php echo $car->colour->title; ?></a></p>
<p>SEATS: <a href="/cars/seats/<?php echo $car->seats->name; ?>"><?php echo $car->seats->title; ?></a></p>
<p>TYPE: <a href="/cars/type/<?php echo $car->type->name; ?>"><?php echo $car->type->title; ?></a></p>

<?php endforeach; ?>

The natural tree structure would be:

site.com/make/mercedes/
site.com/model/e-class/
site.com/year/2005/
site.com/colour/red/
site.com/seats/5/
site.com/type/mpv/

... but I got this working ok without needing URL segments. Just saying so you are aware that I am doing this approach on purpose even though it's not necessary. The code above shows that I added a /cars/ into the anchor tags, thus:

site.com/cars/make/mercedes/
site.com/cars/model/e-class/
site.com/cars/year/2005/
site.com/cars/colour/red/
site.com/cars/seats/5/
site.com/cars/type/mpv/

...I enabled URL segments in the car-index.php template and gave it a shot. So the links with text work:

AT: site.com/cars/make/mercedes/

print_r($cars);
// outputs
ProcessWire\PageArray Object ( [hooks] => Array ( [PageArray::render] => MarkupPageArray->renderPageArray() in
MarkupPageArray.module [PageArray::renderPager] => MarkupPageArray->renderPager() in MarkupPageArray.module )
[count] => 1 [items] => Array ( [0] => /cars/old-banger/ ) [total] => 1 [start] => 0 [limit] => 0
[selectors] => template=car-entry, make=mercedes, status<1024 )

...but the years and seats don't?

AT: site.com/cars/year/2005/

print_r($cars)
// outputs
ProcessWire\PageArray Object ( [hooks] => Array ( [PageArray::render] => MarkupPageArray->renderPageArray() in
MarkupPageArray.module [PageArray::renderPager] => MarkupPageArray->renderPager() in MarkupPageArray.module )
[count] => 0 [total] => 0 [start] => 0 [limit] => 0
[selectors] => template=car-entry, year=2005, status<1024 )

Have I got a typo or something? I thought it was something to do with:

$segment2 = $sanitizer->pageName($input->urlSegment2);

...but even just using:

$segment2 = $input->urlSegment2;

...doesn't work either. Any ideas? Thanks.

--EDIT--

adding another image to show how it's setup in admin.

numbers do work fine in url segments; there must be something going on with your selector, and either some type mismatch, or other issue with the selector;

do you have tracy debugger installed? you can run a series of tests on your selector to make sure it is returning results, and also dump/log the segments or sanitized segments to see what is going on

[SamC]

I don't have tracy debugger installed, I'll look into that.

It's weird though because even manually making the selectors:

Good condition small car

MAKE: Ford
MODEL: Ka
YEAR: 2008
COLOUR: Black
SEATS: 5
TYPE: Other

// no results
$cars = $pages->find("template=car-entry, seats=5");

// no results
$cars = $pages->find("template=car-entry, year=2008");

// returns car above
$cars = $pages->find("template=car-entry, make=ford");

// returns car above
$cars = $pages->find("template=car-entry, model=ka");

// returns car above
$cars = $pages->find("template=car-entry, colour=black");

I can't see the difference between the selectors, other than the first two are numbers.

Try seats.name=5 and year.name=2008

With page reference fields you are supposed to specify the subfield from the page that has been selected. I never actually realized that some work without specifying the subfield, but I just tested an can confirm what you are seeing. Not sure if this is really a bug or not, but I would definitely recommend always specifying the subfield (either name, title, or any other field from the selected page).

As usual @adrian you're spot on. Thanks  now I can move on.
