Pages Export

This module is for specifically exporting ProcessWire 2.x sites for later importing into ProcessWire 3.x.

Github: Project Page

Modules Directory: https://modules.processwire.com/modules/process-pages-export/

Credits: Ryan Cramer

Background

As I make my modules ProcessWire 3.x-compatible only, I've had the need to re-create/mirror their ProcessWire 2.x test sites in respective ProcessWire 3.x sites. These ProcessWire 3.x sites (one for each module) were already in place and I didn't feel like re-doing them by exporting/importing site profiles. I also like working with JSON rather than other export formats. So, I decided to write a custom pages export/import script for moving the ProcessWire 2.x sites to their respective ProcessWire 3.x counterpart sites. I'd just finished the export side of things when I came across a post in the forums that reminded me that ProcessWire 3.x already boasts a pages export/import feature, although some of it is still in development. Great! I like its API (PagesExportImport.php) and GUI (ProcessPagesExportImport.module) so no need to re-invent the wheel. 

I still had the small problem of making sure my JSON export would be compatible with the JSON input that the ProcessWire 3.x import expects. No need to re-invent the wheel, again! I ditched my custom script and instead ported the export functionalities of ProcessWire 3.x Pages Export/Import for use in ProcessWire 2.2 - 2.7, specifically to help migrate older sites to ProcessWire 3.x.

Compatibility

The module and class have been tested and work in ProcessWire 2.2, 2.3, 2.4, 2,5, 2.6 and 2.7.  The module is currently tagged as 'in development' until Pages Import feature of ProcessWire 3.x is released as stable. Nonetheless, I have not encountered any issues so far in either the export or the ProcessWire 3.x import. I think Ryan is waiting until he can support more complex field types before tagging the ProcessWire 3.x Pages Export/Import as production-ready.

This is not a ProcessWire 3.x module and will never be. It has no such need :). Just in case you forget and try to install it in a ProcessWire 3.x site, the module will throw a WireException(). I will also not be porting the ProcessWire 3.x import functionality for use in ProcessWire 2.x. That will defeat the purpose here; to move sites to ProcessWire 3.x and not the other way round.

Supported Fields

  • All non-complex fields such as integer, text, textarea, etc
  • Page fields
  • Repeaters
  • File and Image fields

I think these cover most needs. Note: not yet tested with Multilingual fields.

Technical

To ensure exports will be compatible with ProcessWire 3.x Pages Import, where necessary, the module borrows (and amends as needed) methods from ProcessWire 3.x for use in ProcessWire 2.x. For instance, ProcessWire 3.x Pages Export/Import uses the new(-ish) $file functions found in WireFileTools. Rather than copy and include such files, the module only borrowed and amended needed methods. These are listed below.

PagesExport.php

  • From /wire/core/Functions.php: wireInstanceOf(), wireClassName() and wireClassParents()
  • From /wire/core/Fieldtype.php: getImportValueOptions() and getDatabaseSchema()
  • From /wire/core/WireFileTools.php: zip(), chmod() and mkdir()
  • From /wire/core/WireHttp.php: sendFile
  • From /wire/modules/Fieldtype/FieldtypeFile.module: exportValue() and exportDescription()
  • From /wire/modules/Fieldtype/FieldtypeImage.module: exportValue()
  • From /wire/modules/Fieldtype/FieldtypePage.module: exportValue() and exportValuePage()
  • From /wire/modules/Fieldtype/FieldtypeRepeater.module: exportValue()
  • From /wire/core/Fieldtype/WireTempDir.php: create(), createName() and getTempDir()
  • All the export methods from the /wire/core/PagesExportImport.php class

ProcessPagesExport.module

  • All the export methods from /wire/modules/process/ProcessPagesExportImport/ProcessPagesExportImport.module

Newer methods such as $this->wire() will gracefully degrade to the older wire() function, ensuring smooth and uniform operation in ProcessWire 2.2  - 2.7.

Use

This module and class is for supersusers only and has only 1 aim; to export ProcessWire 2.x sites ready for importing into ProcessWire 3.x sites. You can either install (like any other module) and use the process module (ProcessPagesExport.module) or skip the install and just include and use the class (PagesExport.php) to export your sites.

Both the module (Export GUI) and API require that you are logged in as a supersuser before you can use them. The PagesExport class has a gateway method and option not found in the original class (PagesExportImport). The method export() allows access to the three export methods in the original class, i.e. pagesToArray(), exportJSON() and exportZip(). See example usage below.

GUI/Process Module

On install, the module will create a new admin page Export Pages. Please note that unlike the original code, this page is created directly under /admin/ and not /admin/pages/. Click on Export Pages to start.

Nothing much has changed from the original ProcessPagesExportImport.

In older ProcessWire versions where InputfieldSelector was not available, the module will instead present you with a text input to specify a valid (for that version of ProcessWire!) selector for finding pages. The other two methods for adding pages (add pages manually or add by parent) are still available.

Custom JS ensures older installs without showIf functionality still get the inputfield dependency treatment.

API

export($items, $options) 

PageArray $items: The PageArray to export.

Array $options: In addition to the options in the original class that you can pass to pagesToArray(), there are two more options here. mode to specify the export type (array or json or zip) and fieldNamesExclude, to specify fields to exclude from the export. Note that the original class option fieldNames still works. It's for specifying the fields to include in the export.

 

// API USAGE

// get and include PagesExport class
/* @note: you'll need to include the path differently if you are using the
 class directly without installing the Process module
*/
$path = $config->paths->ProcessPagesExport . 'PagesExport.php';
require_once($path);

// create new instance of the class
$siteExport = new PagesExport();

// find items to export
/* 
	a. export whole site! (minus admin and children)
	careful! in some cases, better to export in batches
*/
//$items = $pages->get('/')->find('has_parent!=2');

// export a batch of pages
$items = $pages->find('template=basic-page|computer');

/* you could also use these methods directly
#$data = $siteExport->pagesToArray($items);
#$data = $siteExport->exportJSON($items);
#$data = $siteExport->exportZIP($items);
*/
$options = array(
	// @kongondo addition: export to screen as 'array' or 'json' OR export to zip
	// zip will be saved in /site/assets/backups/PagesExport/ 
    'mode' => 'array',// array or json or ZIP
	// export only these field names, when specified
    'fieldNames' => array('images', 'files', 'multi_pages'),
	// @kongondo addition: exclude fields from export. Here we exclude 'body' field
	'fieldNamesExclude' => array('body'), 
);
// get the export
$data = $siteExport->export($items, $options);

if(is_array($data)) {
    echo '<pre> EXPORTED SITE USING pagesToArray ';
    print_r($data);
    echo '</pre>';	
}
// JSON export
else echo $data;

Video Demo

(Sorry, long and boring) 

Demo shows various exports from ProcessWire 2.x and their importing into ProcessWire 3.x. Remember the old Skyscrapers site profile? See how a whole Skyscrapers site gets exported from a ProcessWire 2.7.3 site and imported into a ProcessWire 3.x starting from here.

Did you find some problems with upgrading sites from 2.x to 3.x? Just wondering why you would export/import pages rather than duplicate the site then upgrade to PW3?

I needed clean installs free from some modules and pages in the 2.x sites. I didn't want those carrying over into the new install and then uninstalling/deleting them.

      Symprowire is a PHP MVC Framework based and built on Symfony using ProcessWire 3.x as DBAL and Service-Provider
      It acts as a Drop-In Replacement Module to handle the Request/Response outside the ProcessWire Admin. Even tough Symfony or any other mature MVC Framework could be intimidating at first, Symprowire tries to abstract Configuration and Symfony Internals away as much as possible to give you a quick start and lift the heavy work for you.
      The main Goal is to give an easy path to follow an MVC Approach during development with ProcessWire and open up the available eco-system.
      You can find the GitHub Repo and more Information here: https://github.com/Luis85/symprowire
      Documentation
      The Symprowire Wiki https://github.com/Luis85/symprowire/wiki How to create a simple Blog with Symprowire https://github.com/Luis85/symprowire/wiki/Symprowire-Blog-Tutorial Last Update
      16.07.2021 // RC 1 v0.6.0 centralized ProcessWire access trough out the Application by wrapping to a Service https://github.com/Luis85/symprowire/releases/tag/v0.6.0-rc-1 Requirements
      PHP ^7.4 Fresh ProcessWire ^3.0.181 with a Blank Profile Composer 2 (v1 should work, not recommended) The usual Symfony Requirements Features
      Twig Dependency Injection Monolog for Symprowire Support for .env YAML Configuration Symfony Console and Console Commands Symfony Webprofiler Full ProcessWire access inside your Controller and Services Webpack Encore support Caveats
      Symfony is no small Framework and will come with a price in terms of Memory Usage and added Overhead. To give you a taste I installed Tracy Debugger alongside to compare ProcessWire profiling with the included Symfony Webprofiler

      So in a fresh install Symprowire would atleast add another 2MB of Memory usage and around 40ms in response time, should be less in production due to the added overhead of the Webprofiler in dev env

      Hello community!

      I want to share a new module I've been working on that I think could be a big boost for multi-language ProcessWire sites.

      Some background, I was looking for a way for our company website to be efficiently translated as working with human translators was pretty laborious and a lack of updating content created a divergence between languages. I, and several other devs here, have talked about translation integrations and have recognized the power that DeepL has. DeepL is an AI deep learning powered service that delivers translation quality beyond any automated service available. After access to the API was opened up to the US, I built Fluency, a DeepL translation integration for ProcessWire.
      Fluency brings automated translation to every multi-language field in the admin, and also provides a translation tool allowing the user to translate their text to any language without it being inside a template's field. With Fluency you can:
      Translate any plain textarea or text input Translate any CKEditor content (yes, with markup) Translate page names for fully localized URLs on every page Translate your in-template translation function wrapped strings Translate modules Fluency is free, and now so is DeepL
      Since this module was first built DeepL has introduced free Developer accounts that allow anyone to start using Fluency at zero cost and beginning with the version 0.3.0 release Fluency now supports free DeepL accounts. As of June 2021 DeepL supports translation to 26 languages and continues to offer more!
      Installation and usage is completely plug and play. Whether you're building a new multi-language site, need to update a site to multi-language, or simply want to stop manually translating a site and make any language a one-click deal, it could not be easier to do it. Fluency works by having you match the languages configured in ProcessWIre to DeepL's. You can have your site translating to any or all of the languages DeepL translates to in minutes (quite literally).
      Let's break out the screenshots...
      When the default language tab is shown, a message is displayed to let users know that translation is available. Clicking on each tab shows a link that says "Translate from English". Clicking it shows an animated overlay with the word "Translating..." cycling through each language and a light gradient shift. Have a CKEditor field? All good. Fluency will translated it and use DeepL's ability to translate text within HTML tags. CKEditor fields can be translated as easily and accurately as text/textarea fields.

      Repeaters and AJAX created fields also have translation enabled thanks to a JavaScript MutationObserver that searches for multi-language fields and adds translation as they're inserted into the DOM. If there's a multi-language field on the page, it will have translation added.

      Same goes for image description fields. Multi-language SEO friendly images are good to go.

      Creating a new page from one of your templates? Translate your title, and also translate your page name for native language URLs. (Not available for Russian, Chinese, or Japanese languages due to URL limitations). These can be changed in the "Settings" tab for any page as well so whether you're translating new pages or existing pages, you control the URLs everywhere.

      Language configuration pages are no different. Translate the names of your languages and search for both Site Translation Files (including all of your modules)

      Translate all of the static text in your templates as well. Notice that the placeholders are retained. DeepL is pretty good at recognizing and keeping non-translatable strings like that. If it is changed, it's easy to fix manually.

      Fluency adds a "Translate" item to the CMS header. When clicked this opens up a modal with a full translation tool that lets the user translate any language to any language. No need to leave the admin if you need to translate content from a secondary language back to the default ProcessWire language. There is also a button to get the current API usage statistics. DeepL account owners can set billing limitations via character count to control costs. This may help larger sites or sites being retrofitted keep an eye on their usage. Fluency can be used by users having roles given the fluency-translate permission.

      It couldn't be easier to add Fluency to your new or existing website. Simply add your API key and you're shown what languages are currently available for translation from/to as provided by DeepL. This list and all configuration options are taken live from the API so when DeepL releases new languages you can add them to your site without any work. No module updates, just an easy configuration. Just match the language you configured in ProcessWire to the DeepL language you want it to be associated with and you're done. Fluency also allows you to create a list of words/phrases that will not be translated which can prevent items such as brands and company names from being translated when they shouldn't

       
      Limitations:
      No "translate page" - Translating multiple fields can be done by clicking multiple translation links on multiple fields at once but engineering a "one click page translate" is not feasible from a user experience standpoint. The time it takes to translate one field can be a second or two, but cumulatively that may take much longer (CKEditor fields are slower than plain text fields). There may be a workaround in the future but it isn't currently on the roadmap. No "translate site" - Same thing goes for translating an entire website at once. It would be great, but it would be a very intense process and take a very (very) long time. There may be a workaround in the future but it isn't on the roadmap. No current support for Inline CKEditor fields - Handling for CKEditor on-demand hasn't been implemented yet, this is planned for a future release though and can be done. I just forgot about it because I've never really used that feature personally.. Alpha release - This module is in alpha. Releases should be stable and usable, but there may be edge case issues. Test the module thoroughly and please report any bugs via a Github issue on the repository or respond here. Please note that the browser plugin for Grammarly conflicts with Fluency (as it does with many web applications). To address this issue it is recommended that you disable Grammarly when using Fluency, or open the admin to edit pages in a private window where Grammarly may not be loaded. This is an issue that may not have a resolution as creating a workaround may not be possible. If you have insight as to how this may be solved please visit the Github page and file a bugfix ticket.
      Requirements:
      ProcessWire  3.0+ UIKit Admin Theme That's Fluency in a nutshell. A core effort in this module is to create it so that there is nothing DeepL related hard-coded in that would require updating it when DeepL offers new languages. I would like this to be a future-friendly module that doesn't require developer work to keep it up-to-date.
      The Module Is Free
      This is my first real module and I want to give it back to the community as thanks. This is the best CMS I've worked with (thank you Ryan & contributors) and a great community (thank you dear reader).
      DeepL Developer Accounts
      In addition to paid Pro Developer accounts, DeepL now offers no-cost free accounts. Now all ProcessWire developers and users can use Fluency at no cost.
      Learn more about free and paid accounts by visiting the DeepL website. Sign up for a Developer account, get an API key, and start using Fluency today.

      PageViewStatistic for ProcessWire is a module to log page visits of the CMS. The records including some basic information like IP-address, browser, operating system, requested page and originate page. Please note that this module doesn't claim to be the best or most accurate.
      Advantages
      One of the biggest advantage is that this module doesn't require any external service like Google Analytics or similar. You don't have to modify your templates either. There is also no Javascript or image required.
      Disadvantages
      There is only one disadvantage. This module doesn't record visits if the browser loads the page from its browser cache. To prevent the browser from loading the page from its cache, add the following meta tags to the header of your page:
      <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> How to use
      The records can be accessed via the Setup-menu of the CMS backend. The first dropdown control changes the view mode.

      Detailed records
      View mode "Detailed records" shows all visits of the selected day individually with IP-address, browser, operating system, requested page and originate page. Click the update button to see new added records.

      Cached visitor records
      View modes other than "Detailed records" are cached visitor counts which will be collected on a daily basis from the detailed records. This procedure ensures a faster display even with a large number of data records. Another advantage is that the detailed records can be deleted while the cache remains. The cache can be updated manually or automatically in a specified time period. Multiple visits from the same IP address on the same day are counted as a single visitor.

      Upgrade from older versions
      Cached visitor counts is new in version 1.0.8. If you just upgraded from an older version you might expire a delay or even an error 500 if you display cached visitor counts. The reason for this is that the cache has to be created from the records. This can take longer if your database contains many records. Sometimes it might hit the maximally execution time. Don't worry about that and keep reloading the page until the cache is completely created.
      Special Feature
      PageViewStatistic for ProcessWire can record the time a visitor viewed the page. This feature is deactivated by default. To activate open the module configuration page and activate "Record view time". If activated you will find a new column "S." in the records which means the time of view in seconds. With every page request, a Javascript code is inserted directly after the <body> tag. Every time the visitor switches to another tab or closes the tab, this script reports the number of seconds the tab was visible. The initial page request is recorded only as a hyphen (-).

      New in version 1.1.0
      A new feature comes with version 1.1.0 which offers to record user names of loggedin visitors. Just activate "Record user names" and "Record loggedin user" in the module settings.
      Settings
      You can access the module settings by clicking the Configuration button at the bottom of the records page. The settings page is also available in the menu: Modules->Configure->ProcessPageViewStat.
      IP2Location
      This module uses the IP2Location database from: http://www.ip2location.com. This database is required to obtain the country from the IP address. IP2Location updates this database at the begin of every month. The settings of ProcessPageViewStat offers the ability to automatically download the database monthly. Please note, that automatically download will not work if your webspace doesn't allow allow_url_fopen.
      Dragscroll
      This module uses DragScroll. A JavaScript available from: http://github.com/asvd/dragscroll. Dragscroll adds the ability in view mode "Day" to drag the records horizontally with the mouse pointer.
      parseUserAgentStringClass
      This module uses the PHP class parseUserAgentStringClass available from: http://www.toms-world.org/blog/parseuseragentstring/. This class is required to filter out the browser type and operating system from the server request.

      Inertia Adapter ProcessWire Module
      Hello! Long time no see.
      I created this module so you can use Inertia.js (https://inertiajs.com/) with ProcessWire.
      Description
      Inertia allows you to create fully client-side rendered, single-page apps, without much of the complexity that comes with modern SPAs. It does this by leveraging existing server-side frameworks.
      Inertia isn’t a framework, nor is it a replacement to your existing server-side or client-side frameworks. Rather, it’s designed to work with them. Think of Inertia as glue that connects the two. Inertia comes with three official client-side adapters (React, Vue, and Svelte).
      This is an adapter for ProcessWire. Inertia replaces PHP views altogether by returning JavaScript components from controller actions. Those components can be built with your frontend framework of choice.

      Hi all,
      we made a small module for sending SMS via Sms77.io. It supports sending to one and multiple users.
      You can download it from GitHub and follow the instructions on how to install it - it is quite easy. An API key is required for sending, get yours for free @ Sms77 and receive 0,50 €.
      Hope this helps somebody and we are open for improvement suggestions!
       
      Best regards
      André
