Hello, I am the developer of the WordPress mapping plugins Leaflet Maps Marker (https://wordpress.org/plugins/leaflet-maps-marker/) and Maps Marker Pro (https://www.mapsmarker.com). Both plugins include support for different directions providers - one of them is OSRM and directions links are linking directly to map.project-osrm.org <http://map.project-osrm.org> . I noticed that the URL schema I used so far seemed to have changed and the map is now always centered on Washington (example link produced by my plugin currently: http://map.project-osrm.org/?hl=en <http://map.project-osrm.org/?hl=en&loc=48.292787,16.092911&df=0> &loc=48.292787,16.092911&df=0)
I did some research and found that the URL parameters have changed and that new parameters like "center" are required. Anyway I am having issues supporting the new URL scheme, because I only want to set the end point for directions as I do not know where the user wants to start. I tried this by using the following URL for example: http://map.project-osrm.org/?z=13 <http://map.project-osrm.org/?z=13¢er=48.242330%2C16.433030&loc=48.24233 0%2C16.433030&loc=&hl=en&ly=&alt=&df=&srv=> ¢er=48.242330%2C16.433030&loc=48.242330%2C16.433030&loc=&hl=en&ly=&alt=& df=&srv= The main issue is that if only 1 loc parameter is set, the input form field for start point remains empty, resulting in a non usable link for my plugin users. The current workaround for this issue is to set both loc parameters to the same lat+lon values (like http://map.project-osrm.org/?z=13 <http://map.project-osrm.org/?z=13¢er=48.242330%2C16.433030&loc=48.24233 0%2C16.433030&loc=48.242330%2C16.433030&hl=en&ly=&alt=&df=&srv=> ¢er=48.242330%2C16.433030&loc=48.242330%2C16.433030&loc=48.242330%2C16.4 33030&hl=en&ly=&alt=&df=&srv=) - this results in start+end point form fields being populated - anyway this is suboptimal, as the user has to delete the start form field and enter where he wants to start. I searched the wiki but couldnt find a way how this could be solved. Is there a way to use a URL like http://map.project-osrm.org/?z=13 <http://map.project-osrm.org/?z=13¢er=48.242330%2C16.433030&loc=48.24233 0%2C16.433030&loc=&hl=en&ly=&alt=&df=&srv=> ¢er=48.242330%2C16.433030&loc=48.242330%2C16.433030&loc=&hl=en&ly=&alt=& df=&srv= with only 1 loc parameter set which prefills the endpoint for directions so that the user only has to set the start point for directions? If not, is there a chance that the site gets updated to support that? Any help would really be appreciated! best, Robert
