Module: Leaflet Map


Mats

Recommended Posts

Hi to everybody and special thanks to @Mats for sharing this big porting, to @gebeer @netcarver @dab for the hard implementations and  to @Ivan Gretsky to keep it alive again, but also to all the contributors and maintainers of this awesome module. 

I'm testing it and it works really fine and easy.

I would try to add an extra class to the markers and I followed this linked tip to Leaflet.AwesomeMarker properties for the main page with all the markers:

   $options = array(
        'useMarkerSettings' => true,
        'markerFormatter' => function($page, $marker_options) {
            $marker_options['icon'] = $page->icon; // Override the default icon for this marker.
            $marker_options['markerColor'] = $page->color; // Override the default color for this marker.
			// Adding extra classes to this marker ??
            $marker_options['extraClasses'] = 'music-stage'; // Or dynamically from an option field: $page->stage_kind->value
            return $marker_options;
        }, 
...
);

But as you can see from the screenshot below, no classes are added to the icon (there is a blank space instead between the classes into <i></i> tag; actually it's always present, with or without the 'extraClasses' index into $marker_options).

Am I missing something?

P.S. The JS correctly loads  the object properties:

mleafletmap1.addMarkerIcon(L.AwesomeMarkers.icon({prefix: 'fa', icon: 'music', markerColor: 'red', iconColor: 'white', extraClasses: 'music-stage'})

Basically it would be nice to add extra classes to the whole marker (not only to the icon) to manipulate it with js (eg. filtering by type/class on a triggered event such as a button click or select change, or hiding from page if an event date is passed, like for exibitions/music lives and so on).

Does anybody have any suggestions to do this?

Thanks in advance.

Hi, is there anybody that knows how to easly disable "scrollWheelZoom" on admin page editing?

Or is there a "module/field" settings development plan for map options in admin?
(an overrideble setting in the field options could be great).


I find a little annoying the zooming in/out of the map on page scroll.

At the moment I put manually a js line of code in InputfieldLeafletMapMarker.js after line 24

// line 24
var map = L.map(mapElement).setView([lat, lng], options.zoom);

// new line
map.scrollWheelZoom.disable();

But I'm not so happy to modify original modules... (on updates the modifications could be lose).

The second approach that I have succesfully tested is to load a js file in admin, but it needs to completely initialize a new map, only with the add of an option in the declaration of the map init:

var map = L.map('_Inputfield_fm_mappa_map', {center: [lat, lng], zoom: parseInt($('#_Inputfield_fm_mappa_zoom').val()), scrollWheelZoom: 0,} );

$(document).ready(function(){

    if ($('form#ProcessPageEdit').hasClass('YOUR_PW_TEMPLETE_NAME_TO_EDIT')) {

        var mapId = '_Inputfield_YOUR_FIELD_MAP_map';

        var lat = $('#_Inputfield_YOUR_FIELD_MAP_lat').val();
        var lng = $('#_Inputfield_YOUR_FIELD_MAP_lng').val();

            scrollWheelZoom: 0,
        }
        
        // var map = $('#_Inputfield_YOUR_FIELD_MAP_map');

Any suggestions?

Let me encourage you to create a PR) I promise to work with it.

OHHH, SORRY! I've replyed from my co-worker account: I'm Cybermano.

Hi @Ivan Gretsky, as promised I made a PR on GitHub: hope it's ok.

Basically I added a new InputfieldCheckbox in the InputfieldLeafletMapMarker.module fields configuration.

Then I setted it in the constructor and also assigned to a variable into the ___render(): if the checkbox is checked, this variable will inoculate an html class ("scrollwheel-disabled") into the div.InputfieldLeafletMapMarkerMap.

At the end, into the InputfieldLeafletMapMarker.js, if the div has this class assigned, map.scrollWheelZoom.disable() will do the work.

 

Sorry, I didn't found a cleaner way 🤫: hope this could be helpful or of inspiration.🙂

I attach the two file here, too.

I had a problem with PHP 8.1.8 an saving pages containing the field. I got this error:

Quote

Fatal Error: Uncaught TypeError: round(): Argument #1 ($num) must be of type int|float, string given in site/modules/FieldtypeMapMarker/InputfieldLeafletMapMarker.module:193

I changed lines 193 and 194 to make sure all values that get rounded are floats:

 if( ((string) round(floatval($lat), $precision)) != ((string) round(floatval($this->defaultLat), $precision)) ||
     ((string) round(floatval($lng), $precision)) != ((string) round(floatval($this->defaultLng), $precision))) {

Maybe this could be included in a future version?

Cheers,

Hi there,

I'm testing a static call with JS to set a new view of the map (I need it on event change without refreshing the page), as found on Github and Stackoverflow:

// frontend
var mymap = L.map($('#mleafletmap1')).setView([45.53, 10.21], 2);

// backend
var mymap = L.map($('#_Inputfield_fm_mappa_map')).setView([45.53, 10.21], 2);

This produces a TypeError: t.className is undefined.

I looking for a solution, but didn't found it (...and I'm not a skilled js coder).

Does anybody have an idea?

I would advice all you that the geocoder API is no longer accessible in the format of the current module.

I have an error geocoding address and the return message from nominatim.openstreetmap is: 
Using the URL /search/ and /reverse/ (with slashes) is no longer supported.
Change url from /search/?q=Berlin in /search?q=Berlin

Also complete addresses are changed, see below:

File not found: API no longer accessible via this URL

Using the URL /search/ and /reverse/ (with slashes) is no longer supported. Please use URLs as given in the documentation.

Examples how to change the URL:

You use: https://nominatim.openstreetmap.org/search/?q=Berlin
Change to: https://nominatim.openstreetmap.org/search?q=Berlin

You use: https://nominatim.openstreetmap.org/search/US/Texas/Huston
Change to: https://nominatim.openstreetmap.org/search?q=Huston, Texas, US

See github issue #3134 for more details.

See github issue #3134 for more details.

 

Maybe editing ControlGeocoder.js fixes partially the problem?

:343 L.Control.Geocoder.jsonp(this.options.serviceUrl + 'search/', L.extend({
change in
L.Control.Geocoder.jsonp(this.options.serviceUrl + 'search', L.extend({

:370 L.Control.Geocoder.jsonp(this.options.serviceUrl + 'reverse/', L.extend({
change in
L.Control.Geocoder.jsonp(this.options.serviceUrl + 'reverse', L.extend({

 

I have tested with simple addresses (italian street, number and city) ad it works fine again, both search and reverse.
