[OpenLayers-Users] save coordinates of POIs using OpenLayers

[Tobias Wendorff]

Dear OpenLayers-Community,

this is my first post to this list ... I hope, someone could help me
to find a good start into working with OpenLayers :-)

I'm student assistant at the University of Dortmund in Germany.
We've started a project with some students to create a scavenger hunt
("city rallye") with cultural POIs.

Now the students have to insert their collected data into the map.
I think, OpenLayers is a good solution for this.

I've got basic JS skills and I can set up a simple OpenLayers
environment, but I'm looking for something like this:

http://www.openlayers.org/dev/examples/drag-feature.html
That way, the students could easily enter information to the map.

But how can I "grab" the coordinates of the nodes and send it
to a PHP-script (I can script in PHP). Loading data into a
marker-layer isn't a problem for me ... only *saving*.

Could anyone help me please?

Best regards,
Tobias
