      Hello guys,
      I'm trying to figure out how to sync fields and templates between staging and production environments.
      I've found Migrations module by Lostkobrakai, but with use of it all the fields and templates must be created by API, which is kind of uncomfortable.
      I also tried ProcessDatabaseBackups module which can export only certain tables, but I don't think it's the best practice to do that.
      How do you guys solve this problem? It's very annoying to setup everything three times (dev, staging, production).
      Thanks a lot :)

      Hi community, I am wondering if its possible to display languages based on what host/domain has been requested.
      The use case is the following: I have one installation of PW - and within this installation I set up 5 different languages (default, english, spanish, french, dutch). Now I have 3 different domains (domainA.com, domainB.com, domainC.com) and I want to decide which languages to make available based on what domain has been navigated to. 
      For example:
      domainA.com
       - default (domainA.com)
       - english (domainA.com/en)
      domainB.com
        - default (domainB.com)
        - french (domainB.com/fr)
        - dutch (domainB.com/nl)
      domainC.com
        - default (domainC.com)
        - dutch (domainC.com/nl)
      So what I want to achieve is making only these particular languages selectable in the language switcher on the frontend. Since all pages share the same templates and overall site structure I don't see the benefits of running this installation as a multisite setup or would it be better to do so? But I assume that this would be difficult to handle since the default language might change as well. (On the french version of the page, french should be the default language and so on). Any suggestions how to accomplish that? Thanks!

      Hello!
      I am fairly new to Processwire. In the past I used OctoberCMS for my project. But I have more and more multilanguage projects and OctoberCMS don't fit my needs anymore.
      My first question to the community is, is it possible to hide/disable content based on the language. I mean, can a content editor say in German I want this content block and in Englisch I wanna hide this content block, based on the same layout?
      Thanks for your answers.

      Page Query Boss
      Build complex nested queries containing multiple fields and pages and return an array or JSON. This is useful to fetch data for SPA and PWA.
      You can use the Module to transform a ProcessWire Page or PageArray – even RepeaterMatrixPageArrays – into an array or JSON. Queries can be nested and contain closures as callback functions. Some field-types are transformed automatically, like Pageimages or MapMarker.
      Installation
      Via ProcessWire Backend
      It is recommended to install the Module via the ProcessWire admin "Modules" > "Site" > "Add New" > "Add Module from Directory" using the PageQueryBoss class name.
      Manually
      Download the files from Github or the ProcessWire repository: https://modules.processwire.com/modules/page-query-builder/
      Copy all of the files for this module into /site/modules/PageQueryBoss/ Go to “Modules > Refresh” in your admin, and then click “install” for the this module. Module Methods
      There are two main methods:
      Return query as JSON
      $page->pageQueryJson($query); Return query as Array
      $page->pageQueryArray($query); Building the query
      The query can contain key and value pairs, or only keys. It can be nested and 
      contain closures for dynamic values. To illustrate a short example:
      // simple query: $query = [ 'height', 'floors', ]; $pages->find('template=skyscraper')->pageQueryJson($query); Queries can be nested, contain page names, template names or contain functions and ProcessWire selectors:
      // simple query: $query = [ 'height', 'floors', 'images', // < some fileds contain default sub-queries to return data 'files' => [ // but you can also overrdide these defaults: 'filename' 'ext', 'url', ], // Assuming there are child pages with the architec template, or a // field name with a page relation to architects 'architect' => [ // sub-query 'name', 'email' ], // queries can contain closure functions that return dynamic content 'querytime' => function($parent){ return "Query for $parent->title was built ".time(); } ]; $pages->find('template=skyscraper')->pageQueryJson($query); Keys:
      A single fieldname; height or floors or architects 
      The Module can handle the following fields:
      Strings, Dates, Integer… any default one-dimensional value Page references Pageimages Pagefiles PageArray MapMarker FieldtypeFunctional A template name; skyscraper or city
      Name of a child page (page.child.name=pagename); my-page-name A ProcessWire selector; template=building, floors>=25
      A new name for the returned index passed by a # delimiter:
      // the field skyscraper will be renamed to "building": $query = ["skyscraper`#building`"]  
      Key value pars:
      Any of the keys above (1-5) with an new nested sub-query array:
      $query = [ 'skyscraper' => [ 'height', 'floors' ], 'architect' => [ 'title', 'email' ], ]  
      A named key and a closure function to process and return a query. The closure gets the parent object as argument:
      $query = [ 'architecs' => function($parent) { $architects = $parent->find('template=architect'); return $architects->arrayQuery(['name', 'email']); // or return $architects->explode('name, email'); } ] Real life example:
      $query = [ 'title', 'subtitle', // naming the key invitation 'template=Invitation, limit=1#invitation' => [ 'title', 'subtitle', 'body', ], // returns global speakers and local ones... 'speakers' => function($page){ $speakers = $page->speaker_relation; $speakers = $speakers->prepend(wire('pages')->find('template=Speaker, global=1, sort=-id')); // build a query of the speakers with return $speakers->arrayQuery([ 'title#name', // rename title field to name 'subtitle#ministry', // rename subtitle field to ministry 'links' => [ 'linklabel#label', // rename linklabel field to minlabelistry 'link' ], ]); }, 'Program' => [ // Child Pages with template=Program 'title', 'summary', 'start' => function($parent){ // calculate the startdate from timetables return $parent->children->first->date; }, 'end' => function($parent){ // calculate the endate from timetables return $parent->children->last->date; }, 'Timetable' => [ 'date', // date 'timetable#entry'=> [ 'time#start', // time 'time_until#end', // time 'subtitle#description', // entry title ], ], ], // ProcessWire selector, selecting children > name result "location" 'template=Location, limit=1#location' => [ 'title#city', // summary title field to city 'body', 'country', 'venue', 'summary#address', // rename summary field to address 'link#tickets', // rename ticket link 'map', // Mapmarker field, automatically transformed 'images', 'infos#categories' => [ // repeater matrix! > rename to categories 'title#name', // rename title field to name 'entries' => [ // nested repeater matrix! 'title', 'body' ] ], ], ]; if ($input->urlSegment1 === 'json') { header('Content-type: application/json'); echo $page->pageQueryJson($query); exit(); } Module default settings
      The modules settings are public. They can be directly modified, for example:
      $modules->get('PageQueryBoss')->debug = true; $modules->get('PageQueryBoss')->defaults = []; // reset all defaults Default queries for fields:
      Some field-types or templates come with default selectors, like Pageimages etc. These are the default queries:
      // Access and modify default queries: $modules->get('PageQueryBoss')->defaults['queries'] … public $defaults = [ 'queries' => [ 'Pageimages' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'focus', ], 'Pagefiles' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'filesize', 'filesizeStr', 'hash', ], 'MapMarker' => [ 'lat', 'lng', 'zoom', 'address', ], 'User' => [ 'name', 'email', ], ], ]; These defaults will only be used if there is no nested sub-query for the respective type. If you query a field with complex data and do not provide a sub-query, it will be transformed accordingly:
      $page->pageQueryArry(['images']); // returns something like this 'images' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'focus'=> [ 'top', 'left', 'zoom', 'default', 'str', ] ]; You can always provide your own sub-query, so the defaults will not be used:
      $page->pageQueryArry([ 'images' => [ 'filename', 'description' ], ]); Overriding default queries:
      You can also override the defaults, for example
      $modules->get('PageQueryBoss')->defaults['queries']['Pageimages'] = [ 'basename', 'url', 'description', ]; Index of nested elements
      The index for nested elements can be adjusted. This is also done with defaults. There are 3 possibilities:
      Nested by name (default) Nested by ID Nested by numerical index Named index (default):
      This is the default setting. If you have a field that contains sub-items, the name will be the key in the results:
      // example $pagesByName = [ 'page-1-name' => [ 'title' => "Page one title", 'name' => 'page-1-name', ], 'page-2-name' => [ 'title' => "Page two title", 'name' => 'page-2-name', ] ] ID based index:
      If an object is listed in $defaults['index-id'] the id will be the key in the results. Currently, no items are listed as defaults for id-based index:
      // Set pages to get ID based index: $modules->get('PageQueryBoss')->defaults['index-id']['Page']; // Example return array: $pagesById = [ 123 => [ 'title' => "Page one title", 'name' => 123, ], 124 => [ 'title' => "Page two title", 'name' => 124, ] ] Number based index
      By default, a couple of fields are transformed automatically to contain numbered indexes:
      // objects or template names that should use numerical indexes for children instead of names $defaults['index-n'] => [ 'Pageimage', 'Pagefile', 'RepeaterMatrixPage', ]; // example $images = [ 0 => [ 'filename' => "image1.jpg", ], 1 => [ 'filename' => "image2.jpg", ] ] Tipp: When you remove the key 'Pageimage' from $defaults['index-n'], the index will again be name-based.
       
      Help-fill closures & tipps:
      These are few helpfill closure functions you might want to use or could help as a
      starting point for your own (let me know if you have your own):

      Get an overview of languages:
          $query = ['languages' => function($page){         $ar = [];         $l=0;         foreach (wire('languages') as $language) {             // build the json url with segment 1             $ar[$l]['url']= $page->localHttpUrl($language).wire('input')->urlSegment1;             $ar[$l]['name'] = $language->name == 'default' ? 'en' : $language->name;             $ar[$l]['title'] = $language->getLanguageValue($language, 'title');             $ar[$l]['active'] = $language->id == wire('user')->language->id;             $l++;         }         return $ar;     }]; Get county info from ContinentsAndCountries Module
      Using the [ContinentsAndCountries Module](https://modules.processwire.com/modules/continents-and-countries/) you can extract iso
      code and names for countries:
          $query = ['country' => function($page){         $c = wire('modules')->get('ContinentsAndCountries')->findBy('countries', array('name', 'iso', 'code'),['code' =>$page->country]);         return count($c) ? (array) $c[count($c)-1] : null;     }]; Custom strings from a RepeaterTable for interface
      Using a RepeaterMatrix you can create template string for your frontend. This is
      usefull for buttons, labels etc. The following code uses a repeater with the
      name `strings` has a `key` and a `body` field, the returned array contains the `key` field as,
      you guess, keys and the `body` field as values:
          // build custom translations     $query = ['strings' => function($page){         return array_column($page->get('strings')->each(['key', 'body']), 'body', 'key');     }]; Multilanguage with default language fallback
      Using the following setup you can handle multilanguage and return your default
      language if the requested language does not exist. The url is composed like so:
      `page/path/{language}/{content-type}` for example: `api/icf/zurich/conference/2019/de/json`
       
          // get contenttype and language (or default language if not exists)     $lang = wire('languages')->get($input->urlSegment1);     if(!$lang instanceof Nullpage){         $user->language = $lang;     } else {         $lang = $user->language;     }     // contenttype segment 2 or 1 if language not present     $contenttype = $input->urlSegment2 ? $input->urlSegment2 : $input->urlSegment1;     if ($contenttype === 'json') {         header('Content-type: application/json');         echo $page->pageQueryJson($query);         exit();     } Debug
      The module respects wire('config')->debug. It integrates with TracyDebug. You can override it like so:
      // turns on debug output no mather what: $modules->get('PageQueryBoss')->debug = true; Todos
      Make defaults configurable via Backend. How could that be done in style with the default queries?
      Module in alpha Stage: Subject to change
      This module is in alpha stage … Query behaviour (especially selecting child-templates, renaming, naming etc)  could change

      hey there
      I guess a lot of you have already heard of the hreflang attribute which tells search engines which URL they should list on their result pages. For some of my projects I build this manually but now I am wondering if there's need to add this as a module to PW modules directory. 
      How do you deal with the hreflang thingy? Would you you be happy if you can use a module for this or do you have concerns that using a module maybe does not cover your current use cases?
      Cheers,
      Chris
