Hello all,
I've been working on a PHP cURL version of the cURL example that uploads
a ZIP file containing a shapefile and creates a new datastore in Geoserver.
I've been testing it out and have an example that is working for me. I
attached an annotated copy of the script to this email.
This script is based on the POST example in the Geoserver REST Extension
examples and a PHP cURL file upload example from
http://shivakvs.wordpress.com/2009/02/12/file-upload-php/ per Arne
Kepp's suggestion, and the suggestions of the web programmers that I
work with.
Please share any ideas for improvements.
I have a simple web page setup that includes a form with a file input
and a submit button. When that page loads, it also runs a function in
this php file to see if a file is in the request header. If there is,
then the REST Upload script is run.
I think an example similar to this would be nice to have in the REST
Configuration Extension docs.
It's really cool how well these REST tools work.
