Render page with urlsegment from API

[Ivan Gretsky]

Good day!

I need to render a page output for a given url segment from API. There is a way to render a page with $page->render() and now with $page->renderPage(). But I can't find a way to render a page passing in an url segment. So the output would be not of site.com/page but of site.com/page/urlsegment to make it more clear.

Please share your ideas.

Do you mean something like this ?

$segments = ['earth', 'mars', 'jupiter'];

$wire->addHook('(/.*)/(' . implode('|', $segments) . ')', function (HookEvent $event) use ($segments) {
    $path = $event->arguments(1) . '/';

    try {
        $page = $event->pages->get($path);
    } catch (\Throwable $th) {
        $page = new NullPage();
    }

    if ($page->id) {
        header('Content-Type: application/json');
        echo json_encode([
            'path' => $path,
            'segment' => $event->arguments(2),
            'segments' => $segments,
            'page' => $page->title
        ]);
        exit;
    }
});

---

$segment = 'get';
$uri = $_SERVER['REQUEST_URI'] ?? '';
if (str_ends_with(rtrim($uri, '/'), $segment)) {
    $wire->addHook($uri, function (HookEvent $event) use ($segment, $uri) {
        list($path, $empty) = explode($segment, $uri);
        try {
            $page = $event->pages->get($path);
        } catch (\Throwable $th) {
            $page = new NullPage();
        }

        if ($page->id) {
            header('Content-Type: application/json');
            echo json_encode([
                'path' => $path,
                'segment' => $segment,
                'page' => $page->title
            ]);
            exit;
        }
    });
}

This will add a global url hook for url ends with requested segments and you can get page from first url segment than you can print anything you want.

Thanks Iskender!

But that is not exactly what I am after. I need to render a page Page::renderPage hook and replace the output with another page render.

wire()->addHookBefore('Page::renderPage', function (HookEvent $event) {

	/* CONDITIONS CHECKING */

	$event->removeHook(null); // Remove this hook so we do not get caught up in a loop. See https://processwire.com/api/ref/wire/remove-hook/			
	$someOtherPage = wire()->pages->get(...); // Get the page to be rendered instead of the current one

	$event->return = $someOtherPage->render(); // HERE I NEED TO RENDER A PAGE OTPUT FOR AN URL SEGMENT INSTEAD OF REGULAR RENDER

	$event->replace = true;

	...

@Ivan Gretsky, see here for how to render a page with URL segments:

@Ivan Gretsky

Just use Page::render

$wire->addHookBefore('Page::render', function (HookEvent $event) {

    /**
     * @var Page $page
     * @var WireInput $input
     */
    $page = $event->object;
    $input = $event->wire()->input;

    // Use get method: // example.test/about?segment=home
    $segment = $input->get('segment');
    // Allow template url allow segments otherwise you will get 404 error
    $segments = $input->urlSegments();
    // Validate by template
    $page->template->name != 'home';

    if ($segment === 'home' || $page->template->name != 'home') {
        /** @var Page $home */
        $home = $event->wire()->pages->get(1);
        $event->replace = true;
        $event->return = $home->render();
    }
});

Thank you friends! This approach works. The only thing I had to change using $input->setUrlSegment(1, "segment"); instead of dynamic property setting to get rid of warnings in PHP 8.2.
