I'm trying to automatically add pages containing a field with this fieldtype. while all other fields are populated as expected the lat/lng part of my geolocation field keeps its default values. Is there a special syntax to address these

I don't really understand why, but it works, if I change lat lng values in a second step.

$newPoi = $pages->add("tmbPoi", "$parentPage->url", [
                    'name' => $thisPoiId,
                    'title' => $poi['name'],

$newPoi->geolocation->lat = $lat;
$newPoi->geolocation->lng = $lng;

This is a really nice module, but why is the fully working version only in the 'dev' release?

EDIT: Having said that, I now find I have the same problem as the previous poster. It all works fine on my Dev machine. But in the live environment it is blank.

EDIT 2: In my case, the problem was simple - just forgot to upload the additional lines in the <head> - i.e.

    <?php $map = wire('modules')->get('MarkupLeafletMap'); ?>
    <?php echo $map->getLeafletMapHeaderLines(); ?>

Is that your problem @Leftfield?

@MarkE thank you for your answer but it doesn't help since I load files manually (except main js). Anyway, I will remove module for two reasons (both not fault of the module):
First: Lon and Lat are not compatible with Google Maps for my country. There is some wild offset.
Second: Will test for SEO, doubt is that Google doesn't rank website with Open street map.

So using the dev version, the geo coding is working. (also when you add a key to the google geo call). But I now run into an issue where the map is grey out in the "edit page" set-up. I cant fill in an address either as the input field is disabled. @hellomoto mentioned this issue before. Did you got a chance to fix it? @Mats ay pointers?

After spending hours trying to find a solution, I ask the community for help... I have a map showing up on page load. It works fine but it takes quite a while. You can see it in action there : https://planetalert.tuxfamily.org/world/6ef (be patient, loading is terrible)

I have already tried caching parts of my page (the different lists) and it's ok, but I can't manage to cache the map. So I would like to load the 2nd tab (when clicking on the faces icon at the top-left corner) by default to get a fast loading page and have my map loading on an ajax call. But all my tests are complete failures 😞

Here's my ajax part of code :

	[...] // Setting $allElements (for markers) and $options there
	$map = $modules->get('MarkupLeafletMap');
$out .= $map->getLeafletMapHeaderLines();
$out .= $map->render($allElements, 'map', $options);

Eventually, I get my map box, but it stays empty 😞 

Any advice, please ?

@celfred: This has nothing to do with the map itself. It takes 15 seconds four your server to generate a response, after that the map and all of its content loads fast. So I assume your process of building the list of markers is somewhat ineffective. Can you show the code with which you generate the $allElements Array?

@MadeMyDay Thanks for your reply. From your comment, I have tried testing my $allEments function (it takes 0.415s on localhost). You can see the code there : https://framagit.org/celfred/planetAlert/blob/master/site/templates/my-functions.inc (function teamFreeWorld() line 1468) BUT I have also tried this :

	$out .= $map->render($allElements->eq(0), 'map', $options);

And the page now loads a lot faster (I can tell the difference even on localhost) ! So maybe it's because I have 56 (or even 96) markers, with a photo... ? What could I do, then ?

I hope you (or anybody else) will have other pieces of advice for me 🙂 My site has improved so much over the years thansk to the help of this community (and I have learned so much - you can tell I'm not a pro dev 😉 - I'm a teacher and the website is for motivating my middle-school pupils)

EDIT : Well, for the moment, I've just removed the images in my map markers tooltips and it loads faster...

I have this module implemented on a website and all works well. It currently outputs popups as per the attached image – the first line is generated by the module/options but I can't seem to override it in any way. The map pull sin information from it's child pages, and the title in the pop up links to the child page, but I want to change this so it links to the company's website instead (as per the url further down the pop-up). I've tried changing the 'markerLinkField' / 'markerTitleField' options, leaving them blank, etc but that either displays as per the attached or stops the pop up working.

Any thoughts much appreciated.

Issue 1:

Why do I get lots of random Russian (?) text when I try to look up addresses? And the location search results are awful; the system suggests random street addresses (with lots of Russian) when you type in something basic like 'London, England'. Full addresses seem to work better, but only without postal codes - 'nothing found' when you try to search with postal codes included.

Issue 2:

Maps show up in the admin area, but not on the front-end. I have another version of the same site where they do show up on the front-end without problems, so am a bit puzzled where the problem could be. What are typical causes I could check?


The problem with the map not showing up on the front end (Issue 2) had something to do with this error showing up in Chrome Inspect/DevTools:

Uncaught TypeError: $ is not a function at (index):529

Something with jQuery. The error disappeared when I copied module files from another site where Leaflet Map did work. Not sure where the cause of the error is exactly.

is it possible to render the input field on a frontend template (for loggedin users only).

I tried this:

$m = $modules->get('InputfieldLeafletMapMarker');

This generates errors for empty variables.

PHP Notice: Trying to get property 'lat' of non-object in ...\InputfieldLeafletMapMarker.module:102
PHP Warning: Creating default object from empty value in ...\InputfieldLeafletMapMarker.module:102

Hi there,

thanks for providing the Leaflet Map Marker module - very useful!

One thing I couldn't figure though is: how can I set NO default address to a field? I need to have the map as an optional field for a given template.

Thanks for any advice.

Not sure if this is the correct way, but on my map template I wrap my code with:

if($page->marker->address) {



if($page->marker->address) {

	$map = wire('modules')->get('MarkupLeafletMap'); 
	$options = array(

    'markerFormatter' => function($page, $marker_options) {
        			if ($page->marker_icon->title) {
                        $marker_options['icon'] = $page->marker_icon->title;

                    if ($page->marker_colour->title) {
                        $marker_options['markerColor'] = $page->marker_colour->title;

                    // And the icon colour. This is another text field. Colour values like White, Black or an RGB value are ok here.
                    if ($page->marker_icon_colour->title) {
                        $marker_options['iconColor'] = $page->marker_icon_colour->title;
        return $marker_options;

    'popupFormatter' => function($page) {
        $out[] = "<strong>$page->headline</strong>";
        return implode('<br/>', $out);


$content.= $map->render($page, 'marker', $options);


If no address is entered, no map is shown.

Hey there,

I don't know if this might help smeone (and if I did it the right way), but I had an issue as follow : all maps worked on my site except 2 monuments which didn't show any map. I noticed they had a single quote in their name and if I got rid of it the map appeared.

I then ended up doing this (in my '$opitions' array) and it worked :

	'popupFormatter' => function($page) {
 $page->title = str_replace('\'', '\\\'', $page->title); // Dirty hack (no map if single quote in title)
 $out[] = '<strong>'.sprintf(__('In %1$s, in %2$s'), $page->city->title, $page->country->title).'</strong>';
 $out[] = "<p class=\"text-center\"><img src=\"{$page->photo->eq(0)->getCrop('thumbnail')->url}\" /></p>"; // ** NB: Use escaped double quotes if HTML attributes needed **
 return implode('<br/>', $out);

Again, it might sound a bit hacky, but it works for me and maybe it can be useful to someone...

      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
      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

      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.
      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.
      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.
      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.
      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.
      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.
      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.
      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.
      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
