Does anyone know how you can populate the address field from another field on the template ? 

Eg; the title field is holding a country name, therefore would be nice if user does not need to type in country again, map just populates automagically.

Thx,

 

I see at least three options:

  1. An auto-load module (might be an overkill though) that will copy the title to the address
  2. JavaScript via a module like RuntimeMarkup, which you could then hide from being visible on the page. Or even better, the module AdminCustomFiles
  3. Copying and modifying the Leaflet module itself to suit this need

So yes, it is possible :).

If it's the title field you want to populate the address from, you could use a hook to set the address when a new page is added. In /site/ready.php:

$this->pages->addHookAfter('added', function($event) {
    $page = $event->arguments('page');
    if($page->template != 'my_map_template') return;
    $page->my_leaflet_map->address = $page->title;
    $page->save();
});

v2.8.0 is out. It's a trivial fix for a problem with the PW3 FileCompiler (it was inserting the Processwire namespace into PHP-generated js code used on the front end).

NB: The js class now used in the code is jsMarkupLeafletMap instead of MarkupLeafletMap. You may need to adjust your js code to allow for this.

I've also taken the opportunity to bump the field numbers to bring some continuity across the files.

Thanks @dab,

I have the big map working with this code (quite basic)

$items = $page->children;
$map = $modules->get('MarkupGoogleMap');

$content .= $map->render($items, 'map');

 

For the page with turtles I want to have the current turtle on that page to be visible on the map. I have made the following code:

if($page->hasChildren) {
    $results = $page->children("limit=9, sort=-created");

    $pagination = $results->renderPager();

    $content .= $pagination;
   $content .= renderSchildpadden($results);
    $content .= $pagination;
}


foreach ($results as $result){
    foreach ($result->verspreidingen as $verspreiding) {
    $out .= $verspreiding . "|";
    }
    }
//$item = $out;
$sidebar_bottom = $out;

$map = $modules->get('MarkupGoogleMap');

$sidebar_bottom .= $map->render($out, 'map');

The part for the sidebar_bottom gives the following error:

Error: Uncaught Error: Call to a member function first() on string in /home/deb26781n3/domains/chrysemys.nl/public_html/site/modules/FieldtypeMapMarker/MarkupGoogleMap.module:209

This error message was shown because: you are logged in as a Superuser. Error has been logged.

 

The input for the big map are the pages that contain the field 'map'.

foreach ($results as $result){ foreach ($result->verspreidingen as $verspreiding) { $out .= $verspreiding . "|"; } }

The code above produces also an array of pages that contain the field 'map'. But this time the same function strugles on this part of the code in the module:

if($options['useMarkerSettings'] && (count($pageArray) == 1 || !$lat)) {
   // single marker overrides lat, lng and zoom settings
   $marker = $pageArray->first()->get($fieldName); << this line and on first() returns the error
          $lat = $marker->lat;
   $lng = $marker->lng; 
   if($marker->zoom > 0) $zoom = (int) $marker->zoom;
}

What am I doing wrong here?

@webhoes

Are you sure you're posting this issue in the correct place? This thread deals with the Leaflet maps module, but your code looks like it is using the Google maps module.

Is it possible to make this module work like a Choropleth map?

An interactive (vector based) map of all the regions in the world. The coloring should be darker as more pages (are linked) belong to a certain region.

Another awesome option for chloropleth maps is: http://datamaps.github.io/

I haven't used this module, so not sure how to best integrate chloropleth into it, but I am sure someone who has will chime in.

Datamaps works great with PW - no need for a module - just use the dataUrl option and point it to a PW bootstrapped php file which uses PW selectors to grab the required data (Profields Table field works great as a data source, but not necessary), populate an array, and the run json_encode on it. I would recommend starting with a manually populated json file first to make sure you have datamaps working properly, and then work on the dynamically generated file. It's not difficult, but might be a little tricky your first time.

PS Of course if your data is in a non-PW database table, you can do direct SQL queries to build up the array/json

@adrian, I don't fully understand the workflow (yet).

This is an example what I would really like (they have taken it a few steps beyond my initial thoughts which is even nicer).

https://theturtleroom.com/education/native-species-maps/

Can an array be populated with something pages->find() for a big map. And put the Datamaps code in the template for the big map.

 

I have pages with turtles and linked them to other pages that are a country/state. Can I use the same method to creat a map with this instead of google like I have now?

My working example - http://chrysemys.nl/schildpadden/trachemys-scripta-scripta/

Datamaps supports chloropleth and bubbles. I often use the bubbles options for the markers at various locations. You can color and size them as needed and also add a tooltip with more info. You can even add click events to trigger display of further information on the page - perhaps a chart related to turtle info at the click site.

The other great thing about datamaps is that because it outputs as SVG (via D3JS), you can manipulate the elements with css and js very easily. It really is a pleasure to work with. It also works great with AngularJS and I expect it will integrate nicely with VueJS as well (something I plan on trying soon).

You can also use your own map data rather than relying on the built-in world / country maps. You just need to convert ESRI shape files to the topojson format, which is awesome for the web. As you can tell, I am a huge fan of the datamaps library :)

Perhaps you should dive in and ask more detailed questions as they come up - probably time to start a new topic though.

Thanks to @gmclelland, we have a fixed PW3 branch (now at v3.0.2) and some extended documentation for the tile layer support option in both branches.

Does anybody know how to customize the map's javascript options when displaying the map on the frontend?

I'm trying to turn the mouse scrollzoom off.

http://leafletjs.com/reference.html#map-scrollwheelzoom

Also for anybody else having trouble when using this with the TemplateEngineFactory and TemplateEngineTwig modules, I had to do the following because my map wasn't showing on the frontend.  No errors where displayed and the leaflet assets where loaded on the page.  The map just didn't get initialized without the $page->inlineScript.

In my controller.php, note how I had to add the $page->inlineScript:
$leafletHeaderLines = $map->getLeafletMapHeaderLines() . $page->inlineScript;
$view->set('leafletHeaderLines', $leafletHeaderLines );

In my view.twig
{{ leafletHeaderLines }}

Hope that helps someone.

Hi all,

Leaflet is working fine on test pages I made in PW 3.0.58.

Now I have 3 questions:

  1. Did anyone upgrade this module to leaflet 1.0.3 ? 
  2. As a basemap with eventual layers I'm requested to use WMS ( http://geoservices.informatievlaanderen.be/raadpleegdiensten/GRB-basiskaart/wms) Does the module support wms? I tried but I'm doing something wrong it seems ..
  3. On top of that I should use either a .dbf, shx or shp file of which then I can link each row to a page in Processwire. Can this be done?

I have to get started and am hesitating whether PW will be the ideal platform to do this. So, on the first 3 points, is there anyone who could inform me?

@Pretobrazza trying to answer your questions:

1. As stated in the MarkupLeaflet.module file, you are required to add the link to leaflet.js yourself. You can change the version to 1.0.3. Then you also have to change the link to the leaflet css in the same file line 106.
If you decide to use the getLeafletMapHeaderLines method for injecting JS and CSS then you need to change lines  168 and 173.

2. This module does not support wms layers out of the box. You would need to expand the JS logic to use them. Over at leafletjs.com they have a tutorial on how to implement wms layers.
The relevant code section in the module can be found in MarkupLeafletMap.js line 47. Following the tutorial on leaflet.js you might have to alter some other code in that file, too.

3. There is a shapefile plugin for leaflet.js that you could use to draw layers from your shape file. You can use the PW API and some PHP logic to create that shape file from the data in your pages, but I'm afraid this goes beyond the scope of this thread.

This module is designed to draw markers of locations on a map where you can choose different map tile providers and assign custom fontawesome icons to your markers.

All in all I think ProcessWire fits the job very well. But you might be better off just using the inputfield from this module on your pages to input the location data. And then setup the map rendering from scratch in your template file rather then using the render method that MarkupLeaflet.module provides. This should be easier than tweaking the render logic that this module provides.

I can definitly encourage you trying to do this with PW and leaflet.js.

@gebeer

Thank you for all the info! I already prepared long reply but I first want to sort out a little problem I'm having when going to v 1.0.3. The admin side works perfectly but on the front-end the map remains blank and an error is being thrown. In the console I read:

Uncaught TypeError: L.MarkerClusterGroup is not a constructor at new jsMarkupLeafletMap (MarkupLeafletMap.js:54)  -->

var markers = new L.MarkerClusterGroup({polygonOptions: {color: 'teal', weight: 1, opacity: .39, lineJoin: 'round'}});
    var marker = '';

When I cancel out these 2 lines the map shows up but obviously without the markers.

Did anyone encounter the same problem?

ProcessWire 3.0.58  -

I think I tried a quick test not to long ago to update the external libraries, and I believe I ran into the problem with the map not showing and javascript errors displayed in the console.  I haven't had any time to investigate further.

@Pretobrazza I just installed latest version of this module on PW 3.0.47

I updated the getLeafletMapHeaderLines method for injecting JS and CSS then lines  168 and 173 to load @1.0.3.

Then I got a JS error about the MarkerCluster.

I updated all 3 files in the module's assets/leaflet-markercluster/ folder to the latest 1.0.4 versions. You can find them here: https://github.com/Leaflet/Leaflet.markercluster/tree/v1.0.4/dist

After that the map is showing up fine with no errors.

Pls let us know how it goes for you.

Does anyone has tried to show a Leaflet map inside a UIKit modal? The problem is that the map will not be rendered properly.

Screenshot_1.jpg.240c0365f46335f89b596408ff21499f.jpg

I have searched the web but didnt found a working solution. The only one that I have found was https://yootheme.com/support/question/80769 but I cannot adapt it to get it work.

Maybe someone had the same problem and found a working solution.

Best regards

      WHY?
      This module was built to fill the gap between simple $pages->find() operations and complex SQL queries.
      The problem with $pages->find() is that it loads all pages into memory and that can be a problem when querying multiple thousands of pages. Even $pages->findMany() loads all pages into memory and therefore is a lot slower than regular SQL.
      The problem with SQL on the other hand is, that the queries are quite complex to build. All fields are separate tables, some repeatable fields use multiple rows for their content that belong to only one single page, you always need to check for the page status (which is not necessary on regular find() operations and therefore nobody is used to that).
      In short: It is far too much work to efficiently and easily get an array of data based on PW pages and fields and I need that a lot for my RockGrid module to build all kinds of tabular data.

      Hello for all,
      ConfigurationForm fieldtype module is one my experiment from 2016.
      Main target to build this module was to store multiple setup and configuration values in just 1 field and avoid to use 1 db table to store just single "number of items on page", or another db table to store "layout type" etc. Thanks to JSON formatted storage this module can help you to reduce number of PW native fields in project, save DB space, and reduce number of queries at front-end.
      Install and setup:
      Download (at the bottom ), unzip and install like any other PW module (site/modules/...). Create some filed using this type of field (ConfigurationForm Fieldtype) Go to field setup Input tab and drag some subfields to container area (demo). Set "Name" and other params for subfields Save and place field to templates ("Action tab") How to use it:
      In my case, I use it to store setup and configurations values, but also for contact details, small content blocks... (eg. "widgets").
      Basic usage example:
      ConfigForm fieldtype "setup" has subfields:
      "limit", type select, option values: 5, 10, 15, 20
      "sort", type select, option values: "-date", "date",  "-sort", "sort"
      // get page children (items) $limit = isset($page->setup->limit) ? $page->setup->limit : 10; $sort = isset($page->setup->sort) ? $page->setup->sort : '-sort'; $items = $page->children("limit=$limit, sort=$sort");  
      Screenshots:


       
      Notes:
      Provide option to search inside subfields Provide multilanguage inputs for text and textarea field types Provide option for different field layout per-template basis Do not place/use field type "Button" or "File input" because it won't works. Please read README file for more details and examples Module use JSON format to store values. Text and textarea field types are multilanguage compatible, but please note that main target for this module was to store setup values and small content blocks and save DB space. Search part inside JSON is still a relatively new in MySQL (>=5.77) and that's on you how and for what to use this module.
      Thanks:
      Initial point for this fieldtype was jQuery plugin FormBuiled and thanks to Kevin Chappel for this plugin.
      In field type "link" I use javascript part from @marcostoll module and thanks to him for that part.

      Hi guys I'm relatively new to PW and just finished developing a page for a client. I was able to include all necessary functionality using the core fieldtypes but now I it seems that I need to extend them with a custom one. What I need is a simple button, that copies the absolute url (frontend not PW-backend) of the page which is currently edited to the clipboard. As this feature is only needed inside a specific template, I tend to use a custom fieldtype which provides this feature. I've been looking inside the core modules code (eg. FieldtypeCheckbox.module) but I don't really get the structure of it and how its rendered to the admin page. I also didn't find a lot of tutorials covering custom fieldtypes.
      Maybe some of you could give me some tips on how to write a basic custom fieldtype that renders a button which copies the value of
      page->httpUrl() to the clipboard using JS. Thanks!

      Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
       
      WHY?
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
       
      Features/Highlights:
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      Limitations:
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.
