Andrew Spode Miller created COUCHDB-1855:
--------------------------------------------
Summary: POST/GET query is not processing arrays properly
Key: COUCHDB-1855
URL: https://issues.apache.org/jira/browse/COUCHDB-1855
Project: CouchDB
Issue Type: Bug
Components: HTTP Interface
Reporter: Andrew Spode Miller
Sending an array in POST/GET url encoded form is not working correctly.
For example:
?foo[]=bar&foo[]=bar2
OR
?foo[0]=bar&foo[1]=bar2
OR
?foo=bar&foo=bar2
Should be converted to:
foo = ["bar", "bar2"]
Instead, the last element overwrites it. So in the above example, excluding the
2nd variety, you would get:
foo = "bar2"
I can't find a W3C document to back up this behaviour - but certainly in PHP
and Java, this is normal behaviour. jQuery also converts an array into this
format too, so if it's not "standard" it's certainly expected.
According to "rnewson" who I was chatting to on IRC - the reason this is
happening is that the URL query is being converted to a JSON object. Therefore,
two items with the same key name would overwrite each other. He also says the
following:
"yes, I think you'd want to convert "foo=bar&foo=baz" into "foo":["bar","baz"]
instead of [{"foo","bar"},{"foo","baz"}] in couch_httpd_external's
to_json_terms function."
I have put a work around in my own code, so this isn't a priority for me - but
perhaps if someone else already has the relevant bit of code open... :)
