Leaflet Map

Descriere

Add a map generated with LeafletJS: an open-source JavaScript library for mobile-friendly interactive maps. Map tiles are provided by default through OpenStreetMap, or MapQuest (with an app key). Can be set per map with shortcode attributes or through the dashboard settings.

Maps

Simply create a map with:

[leaflet-map]

Lookup an address with:

[leaflet-map address="chicago"]

Know the latitude and longitude of a location? Use them (and a zoom level) with:

[leaflet-map lat=44.67 lng=-63.61 zoom=5]

Add a marker under your map shortcode, like so:

[leaflet-map]
[leaflet-marker]

Want more? Make more (and fit the map to contain all of them):

[leaflet-map fitbounds]
[leaflet-marker address="tokyo"]
[leaflet-marker address="oslo"]
[leaflet-marker address="cairo"]
[leaflet-marker address="toronto"]

You can even add popups (to any shape) with their names:

[leaflet-map fitbounds]
[leaflet-marker address="tokyo"]Tokyo[/leaflet-marker]
[leaflet-marker address="oslo"]Oslo[/leaflet-marker]
...

Add a link to the popup messages the same way you would add any other link with the WordPress editor.

Other Shapes, GeoJSON, and KML

Add a line to the map by adding [leaflet-line]. You can specify the postions with a list separated by semi-colon ; or bar | using lat/lng: [leaflet-line latlngs="41, 29; 44, 18"] or addresses: [leaflet-line addresses="Istanbul; Sarajevo"], or x/y coordinates for image maps.

Add a circle to the map by adding [leaflet-circle]. You can specify the position using lat and lng and the radius in meters using radius. You can also customize the style using Leaflet’s Path options. Example: [leaflet-circle message="max distance" lng=5.117909610271454 lat=52.097914814706094 radius=17500 color="#0DC143" fillOpacity=0.1].

Or you can add a geojson shape via a url (make sure you are allowed to access it if it’s not hosted on your own server): [leaflet-geojson src="https://example.com/path/to.geojson"]. Add custom popups with field names; try out the default src file and fields like so (note fitbounds needs to be on leaflet-geojson (for now)):

[leaflet-map]
[leaflet-geojson fitbounds]{name}[/leaflet-geojson]


name is a property on that GeoJSON, and it can be accessed with curly brackets and the property name.

Image Maps

Alternatively, you could use a plain image for visitors to zoom and pan around with [leaflet-image src="path/to/image/file.jpg"]. See screenshots 3 – 5 for help setting that up.

More

Check out other examples on the Shortcode Helper page in the Leaflet Map admin section.

Check out the source code and more details on GitHub!

Capturi ecran

  • Put the shortcode into the post.
  • See the shortcode play out on the front end.
  • For [leaflet-image] upload an image, and copy the URL from the right-hand side
  • For [leaflet-image] paste that image URL into an attribute titled source: example: src="https://picsum.photos/1000/1000/".
  • See the [leaflet-image] on the front end.
  • If you use [leaflet-marker draggable], then you can drag the marker where you want it, open a developers console, and see the specific shortcode to use.
  • Add geojson via URL: [leaflet-geojson src="https://example.com/path/to.geojson"]
  • MapQuest requires an app key, get it from their website; alternatively, you can use OpenStreetMap as a free tile service (remember to add an attribution where necessary).

Instalare

  1. Choose to add a new plugin, then click upload
  2. Upload the leaflet-map zip
  3. Activează modulul prin meniul ‘Module’ din WordPress
  4. Use the shortcodes in your pages or posts: e.g. [leaflet-map] and [leaflet-marker]

Întrebări frecvente

Can I have an SVG Marker?

Yes! Convert the default marker into an svg with a shortcode like this: [leaflet-marker svg color="white" iconClass="fab fa-wordpress-simple" background="red"] The iconClass is perfect for adding a font-awesome icon.

How do I change the style for lines/geojson?

Pass the style attributes to the respective shortcodes (see all options on LeafletJS):

[leaflet-line color="red" weight=10 dasharray="2,15" addresses="Halifax, NS; Tanzania" classname=marching-ants]
My map now says direct tile access has been discontinued (July 11, 2016); can you fix it?

Yes. Update to the newest plugin version, and reset defaults in settings. You can choose to use MapQuest by signing up and supplying an app key, or use the default OpenStreetMap tiles (with attribution). See Screenshot 8.

Can I add geojson?

Yes, just give it a source URL: [leaflet-geojson src="https://example.com/path/to.geojson"] It will also support leaflet geojson styles or geojson.io styles. Add a popup message with [leaflet-geojson popup_text="hello!"], or add HTML by adding it to the content of the shortcode: [leaflet-geojson]<a href="#">Link here, or use text from a feature property, like {title}</a>[/leaflet-geojson] or identify a geojson property with popup_property, and each shape will use its own popup text if available.

Can I add kml/gpx?

Sure!? Use the same attributes as leaflet-geojson (above), but use the [leaflet-kml] or [leaflet-gpx] shortcode.

Can I add a message to a marker?

Yes: [leaflet-marker message="Hello there!" visible], where visible designates if it is visible on page load. Otherwise it is only visible when clicked.

Can I use your plugin with a picture instead of a map?

Yes: Use [leaflet-image src="path/to/image/file.jpg"]. See screenshots 3 – 5 for help setting that up.

Can I use my own self-hosted Leaflet files?

Yes: It’s been added to the dashboard options!

How can I add a link to a marker?

Use the marker format [leaflet-marker]Click here![/leaflet-marker] and add a hyperlink like you normally would with the WordPress editor.

Can I add a line to the map?

Use the line format [leaflet-line] with attributes latlngs or addresses separated by semi-colons to draw a line: [leaflet-line addresses="Sayulita; Puerto Vallarta"].

Can I add my own attributions to custom tile layers?

Yes: use the keyword attribution in your shortcode (semi-colon separated list of attributions): [leaflet-map attribution="Tiles courtesy of MapBox; Locations contributed by viewers"]

Generating shortcodes is very straightforward, and the ability to use an external geo json file makes it nicely compatable with other tools.

this is one of the best plugins currently to replace google maps. lightweight and hassle-free. only complaint is the setup of the shortcode which could really be improved to be more intuitive and user-friendly.

IT is the best map plugin I have seen. It is so easy to use and we don't need Google Maps. great
