The first selector looks a bit strange to me.

It says: "get the children of the page at path /files/ where its title is the same as the current page I'm on"...mmm.

Could you elaborate a bit more? 🙂

I think your selector should be:

foreach($pages->get("/files/")->children as $folder) {

// code for the first iteration, you are now inside the folder

  foreach($folder->files as $lagu) {

  // here you are iterating on the files

  }
}

so it has to be, nested foreach? Should i add echo between foreach? Thanks

I previously omitted some of your code for the sake of brevity, so yes, you can do whatever you want inside each foreach iteration.

      I was really unsure of how to actually title this post, so I do apologize (if someone has a better idea, I will gladly edit it). I am using the profields: pagetable field to allow people to create their own "content" (copy, image, button, etc etc) and rearrange it. I also included a field called "column_size" using the RangeSlider set to (1-12).
      I guess I'll clarify a bit more on this. I am using flexbox where the "row" is <section></section> and the columns are <div class="column"></div> have given the "columns"  flex: 1 1 0; so no matter how many columns you have, the columns will automatically adjust for new content. Where my confusion is coming in: If a user has set up 3 copy items (with 12, 5, 7 respectfully for the column_size), how do I actually output this in my template? I was going to use a switch statement to handle the various items which I thought made it quite easy, but with closing sections and columns I have confused myself as I assume I need an if statement to check if the column size is > 12, or = 12 to determine the actual closing/opening of sections. I apologize if I have not made this very clear. I am a bit unsure how to word this let alone to go about this. 
      Im very appreciative of for any insight into this.

      So I have been hard at work creating url segments for a template (api) and everything is working swimmingly in creating a simple end point for svelte.js. I have however, run into a few questions that I can wrap my head around.
      In my api template I have:
      if($input->urlSegment1 === 'clients') { header('Content-Type: application/json'); $clients = $pages->find("template=clients"); $client_array = array(); foreach ($clients as $client) { $id = $client->id; $title = $client->title; $url = $client->url; $clientName = $client->client_name; $clientColor = $client->client_color->value; $assigned = $client->assigned_to->user_full_name; $client_array[] = array( 'id' => $id, 'code' => $title, 'name' => $clientName, 'associated_users' => $assigned, 'url' => $url ); } $client_json = json_encode($client_array, true); echo $client_json; } The output json from this is:
      [ { "id":1644, "code":"abc", "name":"Test Name", "associated_users":null, "url":"\/pw\/clients\/abc\/" }, { "id": 1645, "code": "xyz", "name": "Test Name", "associated_users": null, "url": "\/pw\/clients\/xyz\/" }, ] I was curious is it possible to add in "clients" before this output json so it would appear as 
      clients: [ { "id":1644, "code":"abc", "name":"Test Name", "associated_users":null, "url":"\/pw\/clients\/abc\/" }, { "id": 1645, "code": "xyz", "name": "Test Name", "associated_users": null, "url": "\/pw\/clients\/xyz\/" }, ] I was not really sure of how to tackle this in my php code, and have spent more time than I care to admit trying to figure it out. Another question I have is that "associated_users" is returning null, which in this instance is correct. It is a multi page field that is set to pull a custom name field from the users template, ie "Louis Stephens" would be associated with the first page. I understand that I need to use a foreach to get the correct data, but I was really unsure of how to place this inside an array, or update the array with the new data. Any help with any of this would greatly be appreciated.
