Summary:                    [patch] func_uri could use a QSFIELD function to
parse x-www-form-urlencoded data
Description: 
Hi,

I've added a QSFIELD function to func_uri.c to get fields from a
querystring. I thought this would be an acceptable way to read an ordered
dictionary gotten through e.g. func_curl.


[Synopsis]
Gets a single field from a application/x-www-form-urlencoded query string.


[Description]
Returns the URI-decoded content from the <index>-th field with name
<field>
from query string found in variable <varname>.

[Syntax]
QSFIELD(varname,field[,index])


Example:

exten =>
_IDX!,n,Set(qsdata=field1=pe%20%25%40%26%3dna&field1=pe+na2&field2=pena3)
exten => _IDX!,n,NoOp(qsdata is ${qsdata})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field1,-1)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field2,-1)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field1,0)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field2,0)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field1,1)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field2,1)})

Set("qsdata=field1=pe%20%25%40%26%3dna&field1=pe+na2&field2=pena3")
NoOp("qsdata is field1=pe%20%25%40%26%3dna&field1=pe+na2&field2=pena3")
NoOp("qstest pe na2")
NoOp("qstest pena3")
NoOp("qstest pe %@&=na")
NoOp("qstest pena3")
NoOp("qstest pe na2")
NOTICE[4224]: func_uri.c:243 qsfield: Field field2= not found in query
string from qsdata on requested index
NoOp("qstest ")

Do you still want to consider this as something to include, or are you
happy with the way you've solved the problem?

John, Russell, and myself don't quite understand what this is trying to
do. Perhaps we need a "dumbed down" example :D
