Have you looked at the instructions for URL Segments?

Yes, how do i add url segment to whitelist? Without manually adding...

[zoeck]

if($input->urlSegment1 == 'photos') {
  // display photo gallery
} else if($input->urlSegment1 == 'map') {
  // display map
} else {
  // display main content
}

You mean like this?
Or what exactly do you mean by whitelist ("Without manually adding"?!)

You can use this to change the template settings’ valid UrlSegments: https://processwire.com/api/ref/template/url-segments/.

Be aware this persists the change immediately, without having to call $template->save()!

You can also use property syntax:

//Add UrlSegments “login” and “logout” to whitelist of current page’s template:
$page->template->urlSegments = array_merge($page->template->urlSegments, ['login', 'logout']);

If you have this requirement, it’s probably worth checking out the relatively new URL hooks: https://processwire.com/blog/posts/pw-3.0.173/

That didn't work, for me it worked like this:

$template = $templates->get('home');

$template->urlSegments = array_merge($template->urlSegments, ['new_city']);

$template->save();

 

ChatGPT helped ?

Not sure I understand the question exactly, but the general way to handle URL segments is in the template file. The template setting is just for if you only have one or two fixed segments or have some reason not to use the template file.

So in your template file you just throw a 404 if the segment doesn't match your allowed segments, which could be defined dynamically. E.g.

// Throw 404 if segment1 isn't in the array of allowed segments (which you could define dynamically)
if($input->urlSegment1 && !in_array($input->urlSegment1, $my_allowed_segments)) throw new Wire404Exception();

// Throw 404 if there is more than one segment when there shouldn't be
if($input->urlSegment2) throw new Wire404Exception();

// Now generate output according to segment, no segment, etc...

I understand, for example, that today there is a pharmacy in this city, and tomorrow it stopped working with us, and if this pharmacy is the only one in the selected region, then it is removed and, of course, the city must be removed, everything happens dynamically. I just switch from yii2 to processwire, everything happens dynamically there without manual intervention.

Okay, so, I didn’t think this should happen and indeed it usually doesn’t, but it definitely happens… sometimes??? This is the code I used to test it initially, just at the top of my home template. I visited the page, checked the UrlSegments in the admin and there they were:

header('content-type: text/plain');
$page->template->urlSegments = array_merge($page->template->urlSegments, ['hello', 'world']);
die();

I tried looking into core/Template.php but nothing seems suspicious… No idea what’s going on but I can reproduce the behaviour on two separate installations, one running 3.0.208 dev and one 3.0.191 dev. I’m not going to investigate this further and blame it on a module or a dumb hook I have set up, but I’m weirded out.
