  1. 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 :)
  2. 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
  3. I'm displaying a list of products which are found by their templates, but the pages are taking a very long time to load. At first, I blamed it on my image rendering (using PIM2), but even with all those images now stored in the file tree, the page is taking abysmally long to load. ProCache seems to help but I don't feel as though what I'm trying to do should be gnawing the bones of my resources quite so long. The variable for the selector is defined in my header include: $productCatList="prod_series|prod_series_ethernet|prod_series_access|prod_series_accessories|prod_series_fiber|prod_series_pwr_supplies|prod_series_pwr_systems|prod_series_wireless"; $getCurrentProdOptions="template=$productCatList, prod_status_pages!=1554|1559|1560|4242"; Then in the template for the page upon which the directory loads: $products = $pages->find("$getCurrentProdOptions"); include_once("./prod-list-row.inc"); echo $out; And the prod-list-row.inc foreach (which is on every page that's exhibiting the slowdown): <?php $sum = 0; $out =""; $out .= "<div class='span_12_of_12'>\n"; foreach($products as $p){ $sum += 1; if ($sum % 2 == 0) { $bgcolor = '#fff'; } else { $bgcolor = '#e4e4e4';} $par = $p->parent; $out .="<div class='section group' style='background: $bgcolor ; min-height: 110px'>\n"; $img = $p->prod_image; $thumb = $img->pim2Load('squarethumb100')->canvas(100,100,array(0,0,0,0),'north',0)->pimSave()->url; $out .="<div data-match-height='{$p->title}' class='col span_2_of_12 hide'>"; $out .="<a href='{$p->url}'><span class='product-image-box'><img src='{$thumb}' alt='{$p->title}' title='{$p->title}'></span></a>"; $out .= "</div>"; $out .= "<div data-match-height='{$p->title}' class='col span_6_of_12'>"; $out .= "<div class='prod-list-name-label'><a href='{$p->url}'>{$p->title}</a></div>"; if($page!=$par) { $out .= "<div class='prod-list-category-label' style='font-size: .7em;'>Category: <a href='{$par->url}'>{$par->title}</a></div>"; } $out .= "<div class='list-headline' style='font-size: .8em;'>{$p->headline}</div>"; $out .="<div class='learn-more-buttons-sm'>"; $out .="<a href='{$p->url}' title='Product Specs and Documentation'><span class='find-out-more-button' style='font-size: .8em;'><i style='font-size: .8em;' class='fa fa-lightbulb-o' ></i> &nbsp; Learn More</span></a>"; $out .="</div>"; $out .="</div> \n"; $out .= " <div data-match-height='{$p->title}' class='col span_4_of_12'>"; if(count($p->prod_feat_imgs) >0 ){ $out .= "<div class='featured-icons-list' margin: 2em .5em;'>"; foreach($p->prod_feat_imgs as $feat){ $icon = $pages->get("$feat->prod_featicon_pages"); if($icon->image) { if($feat->prod_feat_textlang) { $icontitle = $feat->prod_feat_textlang;} else {$icontitle = $icon->title;} $out .= "<img src='".$icon->image->size(35,35,$imgOptions)->url . "' alt='" . $icontitle . "' title='" . $icontitle . "' class='listing-feat-icon' style='margin-right: .5em;' />"; } } $out .= "</div>"; if($p->prod_product_line){ foreach($p->prod_product_line as $pline) if($pline->image) { $out .= "<div style='height: 35px;'>\n"; $out .= "<img src='{$pline->image->size(75,35,$imgOptions)->url}' alt='{$pline->title}' />"; $out .= "</div>"; } } } $out .= "</div>"; $out .="</div>"; } $out .= "</div>"; Is there a clear culprit here of what I'm doing that's so stressing the system? I turned off TracyDebugger because I saw another thread about that causing slowdown (even though I'm using the latest), but that had no effect. Every time I thought I found the culprit and commented it out, nothing changed. Would appreciate some more eyes on this. Thank you! ETA: prod_feat_imgs is a repeater field which contains a Page reference field (from which I pull the image and title) and a multilanguage textfield (to override the page reference title if it exists). Could that be the problem?
  4. With Microsoft Azure recently releasing proper Linux and native Mysql hosting, it is becoming very easy to get processwire hosted on that platform. By default, they force SSL connection to the managed Mysql server. This causes processwire to fail when trying to connect. I can turn off SSL for my MySql server, but I wish there was a $config setting like $config->useSSL = true that would allow processwire to include the appropriate property in the connection string (like ssl=true or whatever). Here is the Azure link that explains what I would like to do: https://docs.microsoft.com/en-us/azure/mysql/concepts-ssl-connection-security Am I missing this config setting somewhere? Or would it be easy to add? Thanks.
  5. Hi there, I was wondering if page->url and page->httpUrl are stored anywhere in the backend? I haven't been able to locate it so I'm beginning to think these are generated or calculated on the fly? Thanks in advance
  6. Hi there, I am writing a module for people who want to import their products from the prestashop database to a new PW website. But if the database of the customer has another prefix then my database, they can't run the code or their needs to be a possibillity to input their own prefix. So I've added a field where you can input the prefix for the database, but then that inputted prefix needs to be set in the query. I tried the following: $categories = $prestashop->prepare(" SELECT .... ..... FROM :prefix_category c etc etc and then in the function to import the categories: $prefix = $this->session->dbPrefix; $categories = $this->get_category(); $categories->execute(array(':prefix'=>$prefix)); $categories->fetchAll(PDO::FETCH_ASSOC); But if I run the code, I get the following error: ImportPagesPrestashop: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens Does anyone have an idea how to solve this? Is it possible to make this changeable or should the customers change their prefix to the same prefix as mine? I hope someone has an idea.... (Sorry if you don't understand it. English isn't my native language).
  7. hey! i want to read a value from a $page which is a multilanguage-field. it is important for me that i get that field NOT language-filtered, so the whole JSON string '{"0":"abdc","1063":"rguer"}'.. is this somehow possible without switching the fileld to not-multilanguage? because i need the filtered output at other places... is there a possibility to read the RAW data? thanks!
  8. I'm looking at the session information in the database. The "ts" column shows my local time formatted as text. The code in the wire/core/sessions.php file shows a check against the normal PHP/Unix "time()" function, which is GMT/UTC time. Shouldn't the timestamp in the DB be GMT/UTC? And pardon the next question; I'm still trying to grasp the structure of PW. How/where does Session.php fetch the 'ts' column from the database? I was trying to track down the answer to my own questions but couldn't find where the 'ts' column gets used. Context - I'm writing a lazy cron job to delete files if the session they are associated with has expired. It seems like the sessions in the DB need to be cleaned up as well - if I explicitly logout the session is deleted. But there are leftover sessions from months ago in the DB, so it looks like old sessions that just don't come back don't get deleted because the expiration logic doesn't delete the session record when it determines the session timed out.
  9. Hello everyone, I'm a PW newbie. Overwhelmed from all I've seen and tried out the last few days. My CMS of choice the last couple of years has been MODX. Other than that, I am working as a frontend and backend developer since over 10 years. Having so much freedom to work directly with PHP inside a CMS / CMF is a relief. No new pseudo scripting language one has to learn (as in Typo3), no unnecessary restrictions or bloat. So, my first general question: If I have an existing dataset in mySQL, that I would like to manage with PW (i.e. inside the admin area of PW) - how would I most likely do that? I know I could export the database tables to PW pages. But what if I wanted a database CRUD system inside the PW area? In MODX "Evo" you could build a custom module for such things. You know - phpMyAdmin is over the top for most clients, and an admin section with a different login and URL is clutter. How can I extend the PW backend? Is it possible to include an off-the shelf CRUD script somewhere? Is that not possible with PW? Or frowned upon? I'm just trying to see what the "best practises" are for these kinds of scenarios. Thanks for explanations, tips and pointers.
  10. I have setup a simple tagging facility. Afterwards I saw Nico's BundleBlog and noted it uses /tags/. So I decided to change my setup from references to fields, templates, etc that were 'tags' to 'tagging'. I used 'Edit field: tags > Duplicate/clone this field'. That gave me 'tags_1'. I then edited 'tags_1' and went to rename it to 'tagging' and hit an error, PW said this name already existed. It seems from my trial/error/learn process I have ended up with at least two fields in my database (seen via MySQL) that aren't listed under Amin > Setup > Fields and one of those is called 'tagging'. What is the best way to clear old/unused things, or, is this an edge case and it's only my trial and error steps that have led to this odd situation and ought I do make a new PW install and manually copy settings over. I don't mind doing that at all, my only concern is that I'd like to learn from this so were this a larger site I could perhaps recover in a more subtle (and quicker) way. Thanks in advance for any pointers. PS: The error is Table 'tmp_field_tagging' already exists PPS: I've got around this by using the new name of 'tagged' instead of 'tagging', but I'd love to learn if defunct bits of my database can be safely cleared out somehow, e.g. I now have these four fields and yet only one will be used. PPPS: Thinking about this, I will need to learn how to clear out old unused db items as I will be using Nico's Blog Module and that will need 'tags' to be gone. On reflection I think I was caught out by this/surprised as I assumed deleting a field would delete part fo the db that had been created to represent that field.
