Help with multisite tagging system - ASMSelect selectable pages and Multisite setup

Recommended Posts

Wondering if anyone can help me get past a sticking point.  

I'm setting up a Processwire instance in a multiple site setup (using Soma's multisite) to run several related websites.  I am getting stuck on the tagging system that I am using (adapted from a standalone PW site I'm running).  I have the tags themselves set up as Pages, and the Tags field on the related pages is and ASMselect field that populates based on the pages underneath /tags/ in the tree.  This system works fine on the standalone site.

Where I am running into issues, is with trying to use them with the multisite setup.  Specifically, choosing the proper subset of pages for tags on the ASMselect input tab.  I want to choose only the tag pages for the site in question.  

My tree is laid out like this:

Multisite / 

          | site1.com

               | subsections

          | site2.com

               | subsections

          | Tags

               | site1.com

                    | tagA

                    | tagB

               | site2.com

                     | tagC

So far, the best I've been able to do is to use  'parent.has_parent=/tags/' in the Custom Find or Selector String portion of the Selectable Pages section of the input.  This gives me the options of choosing tagA, tagB, or tagC on a page under site1.com.  What I'd like to find is a selector that allows me to only see tagA, tagB as options from a page under site1.com and only tagC on a page under site2.com.

Elsewhere in my php templates, I'm using $page->rootParent->title to set the proper scope and URLs for things, but I have not found a way to get that to work in this field input setup.  I am trying to avoid creating specific fields and templates for each site, as unified templates were part of the purpose of going with a multisite install.

 

Thanks in advance for any ideas.

Short answer: this sounds like a use case for the "Custom PHP code" option of the Page field you're storing tag references into. This way you can do a lot more than with just selectors.

Thanks, @teppo, I looked into that.

I went with the following:

$wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) {
  $page = $event->arguments('page');
  $siteName = $page->rootParent->title;
  $parentSelector = 'parent=/tags/'.$siteName.'/';
  if($event->object->hasField == 'Tags') {
    $event->return = $event->pages->find($parentSelector);
  }
});

This selects the right tags now in the ASMselect input field.  I did have to abandon letting new Pages be created from the template, as it was not placing them in the correct place in the tree (It was dropping them in /tags/ instead of /tags/sitename/) and had to remove the required parent (previously set to /tags/) as it wasn't detecting the proper parent on the tags, so wouldn't save them to the page in question.

But at the cost of manually creating the tag pages, the rest of the solution seems to work!

You could try out the idea for "Dynamic parent and/or template for pages created from the inputfield" outlined in this post:

      This module lets you add some custom menu items to the main admin menu, and you can set the dropdown links dynamically in a hook if needed.
      Sidenote: the module config uses some repeatable/sortable rows for the child link settings, similar to the ProFields Table interface. The data gets saved as JSON in a hidden textarea field. Might be interesting to other module developers?
      Custom Admin Menus
      Adds up to three custom menu items with optional dropdowns to the main admin menu.
      The menu items can link to admin pages, front-end pages, or pages on external websites.
      The links can be set to open in a new browser tab, and child links in the dropdown can be given an icon.
      Requires ProcessWire v3.0.178 or newer.

      Setting child menu items dynamically
      If needed you can set the child menu items dynamically using a hook.
      Example:
      $wire->addHookAfter('CustomAdminMenus::getMenuChildren', function(HookEvent $event) { // The menu number is the first argument $menu_number = $event->arguments(0); if($menu_number === 1) { $colours = $event->wire()->pages->findRaw('template=colour', ['title', 'url', 'page_icon']); $children = []; foreach($colours as $colour) { // Each child item should be an array with the following keys $children[] = [ 'icon' => $colour['page_icon'], 'label' => $colour['title'], 'url' => $colour['url'], 'newtab' => false, ]; } $event->return = $children; } }); Create multiple levels of flyout menus
      It's also possible to create multiple levels of flyout submenus using a hook.

      For each level a submenu can be defined in a "children" item. Example:
      $wire->addHookAfter('CustomAdminMenus::getMenuChildren', function(HookEvent $event) { // The menu number is the first argument $menu_number = $event->arguments(0); if($menu_number === 1) { $children = [ [ 'icon' => 'adjust', 'label' => 'One', 'url' => '/one/', 'newtab' => false, ], [ 'icon' => 'anchor', 'label' => 'Two', 'url' => '/two/', 'newtab' => false, 'children' => [ [ 'icon' => 'child', 'label' => 'Red', 'url' => '/red/', 'newtab' => false, ], [ 'icon' => 'bullhorn', 'label' => 'Green', 'url' => '/green/', 'newtab' => false, 'children' => [ [ 'icon' => 'wifi', 'label' => 'Small', 'url' => '/small/', 'newtab' => true, ], [ 'icon' => 'codepen', 'label' => 'Medium', 'url' => '/medium/', 'newtab' => false, ], [ 'icon' => 'cogs', 'label' => 'Large', 'url' => '/large/', 'newtab' => false, ], ] ], [ 'icon' => 'futbol-o', 'label' => 'Blue', 'url' => '/blue/', 'newtab' => true, ], ] ], [ 'icon' => 'hand-o-left', 'label' => 'Three', 'url' => '/three/', 'newtab' => false, ], ]; $event->return = $children; } }); Showing/hiding menus according to user role
      You can determine which menu items can be seen by a role by checking the user's role in the hook.
      For example, if a user has or lacks a role you could include different child menu items in the hook return value. Or if you want to conditionally hide a custom menu altogether you can set the return value to false. Example:
      $wire->addHookAfter('CustomAdminMenus::getMenuChildren', function(HookEvent $event) { // The menu number is the first argument $menu_number = $event->arguments(0); $user = $event->wire()->user; // For custom menu number 1... if($menu_number === 1) { // ...if user does not have some particular role... if(!$user->hasRole('foo')) { // ...do not show the menu $event->return = false; } } });

      I have a template for courses for a website on training.  Within the template I use a multiselect page reference field to define attributes associated with the course. While rendering the page I want search for a combination of attributes -in the multiselect page reference field - presence and absence of some of them -- and perform an operation accordingly. How do I search for a combination of values in the multiselect page reference field? Thanks.
      Here is the pseudo code:
      if ($page->pageReferenceField->has("title=one|two") && $page->pageReferenceField->doesnothave("title=three")) { echo ...; }

      Hi there
      Short version of question
      Let's say I have a page in the admin that contains a field... Is it possible to output the content from that field on another page in the admin? Almost like a reference.
      Longer version of question (with example)
      A house builder with multiple (60+) developments. They want to be able to create notices/messages that can be added to one or many developments. Handy for things like regional covid lockdowns or temporary office closures due to bad weather.
      My approach for the admin editing options:
      Add each message to each development
      Pros: You edit the message on the development page in context
      Cons: Very time consuming and repetitive if the same message needs to be applied to 60+ developments
        Control all the messages from one admin page and say which development each message should be applied to
      Pros: Easier to add/remove messages to more than one development at a time. Control all messages from one place.
      Cons: Content is not added on development page, which is where typical admin users may expect to find it I went for option 2 due to flexibility, and created a page within the admin for global development notices. This contains a repeater with:
      Field for message to display Checkbox list of all developments. The user can select which ones to apply each message to It's working really well but the only thing is that if the user goes to a specific development in the admin, the relevant messages aren't displayed in context (as they aren't edited on that page and instead on the global development notices page)... which may cause confusion when a new staff member / content admin tries to edit the text but there is no field when they go to the development admin page where they expect to see it...
      Solution???
      I don't require the message(s) to also be editable on the development page, but I wondered if there was a nice way to show it/them somehow. I feel like I am missing something really simple as I'm sure ProcessWire will have a nice way of achieving this, or maybe there are field settings that allow this kind of thing to happen?
      Any ideas on approaches or similar experiences would be much appreciated, even if it is just a much simpler example with the content from one field being shown on another admin page to get the ball rolling.
      Thanks in advance for any advice :)

      Hi,
      I would like to set an admin template to 'https only' as recommended in the Processwire security docs.
      However if I do this it forces this setting locally too, resulting in https://localhost requests which result in an error page.
      Is there a simple way round this? Setting https for templates in the config?
      Thanks!

      Hi,
      I'm looking at how I might achieve the following with Processwire:
      A low-bandwidth version of a website, on a subdomain (eg text.mydomain.com), where the content/database is exactly the same as the top level domain, but a new set of templates is used so the site is stripped back to just very simple CSS/low quality images.
      I'm looking and trying to work out what might be best — is it multi-site from the same database? Multi-instance? API? 
      Any guidance or experience of a similar setup would be much appreciated.
