Support for POST method

Issue Summary

Thanks for this module.

The only issue I face so far is that with a long list of fields and/or field data, I get a watchdog warning about overlong referer when I submit the new node form. This is because of use of URL parameters passed via the GET method.

Could we add a POST method to give users a choice of submitting the prepopulated fields without encountering the overlong fields/data URL warning ?

I did a quick hack to convert from $_GET to $_POST. Additional, I added a urldecode on data that contains % (which arises when a space was encountered). So far this works with my data which are either alphanumeric+space or decimal numeric.

If there's demand, perhaps, we could incorporate a dual handling for GET and POST methods, whereby if no URL parameters were found, it looks for POST variables. Or alternatively, just a simple GET vs POST priority (whichever has at least one variable); OR even a combination of both method's variables whereupon duplicate variables encountered are resolved via priority of one over the other.

Any interest in this ?

Mine has mainly been to avoid the watchdog warnings clog up my logs.
