Leaflet Map

Description

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

Height, width, latitude, longitude and zoom are the basic attributes:

[leaflet-map height=250 width=250 lat=44.67 lng=-63.61 zoom=5]

However, you can also just give it an address, and Google (by default) will look it up for you:

[leaflet-map address="Oslo, Norway"]

The default URL requires attribution by its terms of use. If you want to change the URL, you may define a new attribution, or remove the attribution. You can define this site-wide in the admin, or you can set this per map in the shortcode (0 for disabled):

[leaflet-map attribution=0]

OR

[leaflet-map attribution="Copyright @bozdoz"]

Look at other examples on the Shortcode Helper in the Leaflet Map admin section.

Markers

Add a marker to any map by adding [leaflet-marker] after any [leaflet-map] shortcode. You can adjust the lat/lng in the same way, as well as some other basic functionality (popup message, draggable, visible on load). Also, if you want to add a link to a marker popup, use this syntax: [leaflet-marker]Message here: click here[/leaflet-marker] and add a link like you normally would with the WordPress editor.

Lines and other Shapes

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.

Or you can add a geojson shape via a url (work in progress): [leaflet-geojson src="https://example.com/path/to.geojson"]

Image Maps

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

Check out the source code on GitHub!

Shoot me a question @bozdoz.

Screenshots

  • 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: source="http://lorempixel.com/1000/1000/".
  • See the [leaflet-image] on the front end.
  • If you use [leaflet-marker draggable=true], 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).

FAQ

Installation Instructions
  1. Choose to add a new plugin, then click upload
  2. Upload the leaflet-map zip
  3. Activate the plugin through the ‘Plugins’ menu in WordPress
  4. Use the shortcodes in your pages or posts: e.g. [leaflet-map] and [leaflet-marker]
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 identify a geojson property with popup_property.

Can I add kml?

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

Can I add a message to a marker?

Yes: [leaflet-marker message="Hello there!" visible="true"], 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 source="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"]

Reviews

Ein tolles Plugin

einfach zu bedienendes Plugin laßt wenig Wünsche offen, eigene Marker Icons funktionieren gut.
Was mir zur Zeit noch fehlen würde wäre wenn die Icons, die in kml definiert sind auch angezeigt würden. Wenn dann noch MarkerCluster gingen, dann wüßte ich nichts mehr was fehlen könnte.
