如何使用SLIM Framework PHP在URL中传递ID？

Question

I'm new to using SLIM framework, I'm working on a project/platform that allows users to post their listings and take bookings from potential clients. But I want them to be able to share a link to their listing.

I have provided the relevant code below, that is used to display all these listings on a single page. When clicking on one of the listings, the information is pushed into a modal. I'm looking to generate a link for each listing that can be shared via email or message and accessed easily.

At the minute I'm stuck with:

localhost/listings

My desired outcome is:

localhost/listings/+itemid/

Listings.html

function listingInfo($id,$location){

  // Detail View Specific

  $('.listing-info-container').addClass('active');
  $('.listing-info').html('').removeClass('active');
  showLoader($('.listing-info'));
  showLoader($('.listings-results'));

  setTimeout(function(){
    $.ajax({
      method: "GET",
      url: "/listing_information/"+$id
    })
    .done(function(result){
      $('.listing-info').html(result).addClass('active');
      hideLoader($('.listing-info'));
      hideLoader($('.listings-results'));
      // hide map if on mobile - link to external google maps site instead
      $('.listings-map').toggleClass('is-hidden', isMobile());
      // set co-ord vals in hidden textbox
      $('#listing-detail-directions-ll').val($location.toString().replace(/["'()]/g,'').replace(' ', ''));
    });
  }, 1000);

Listings.php

   //to display all listings on a single page
$app->get('/listings', function ($request, $response, $args) {
      $variables['title'] = 'Listings';
      $variables['categories'] = $this->db->select('listing_categories','*');

      return $this->view->render( $response, 'listings.html', $variables,);
    });

Answer 1

Just mention the parameter in the route description like this:

$app->get('/listings/{id}', function ($request, $response, $args) {
...

Then you'll be able to access it within the route handler:

$route = $request->getAttribute('route');
$listingId = $route->getArgument('id');

Answer 2

Is this what you are looking for?

$app->get('/api/:version/users/:id', function ($version, $id) {
    // you can access $version and $id here
}

Answer 3

The simplest way to do this on Slim v3 is:

$app->get('/listings/{id}', function ($request, $response, $id) {
    // do something with $id here
}

Since the parameter value gets captured by {id} and stored in the $id variable.
