I am hoping someone can spot what is missing here. I am getting null result
from curl-ing a page with json post variables.
I try this url in my Firefox browser -
http://www.targetsite.com/search.php#somevar.someothervar
(#somevar.someothervar are irrelevant, I think, as I get the curl variables
from Firebug below.)
In Firebug, this shows:
POST http://www.targetsite.com/ajax/search.xml
In Firebug, below this link are tabs for: Headers, Post, Response, XML and
Cookies. Post tab shows like:
JSON
VAR1 1
VAR2 "2012-09-12"
VAR3 null
CACHED []
OPTIONS null
To prove there is output, the Firebug Response tab shows:
<?xml version="1.0" encoding="utf-8"?>
<JSON> various JSON encoded stuff </JSON>
The above is what I am trying to curl.
My php code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
//target page from Firebug above:
curl_setopt($ch, CURLOPT_URL,
"http://www.targetsite.com/ajax/search.xml";);
//I was not sure how to represent CACHED [], so set it to null
try "CACHED"=>array()
$data = array(
"VAR1" => 1,
"VAR2" => "2012-09-12",
"VAR3" => null,
"CACHED"=>null,
"OPTIONS"=>null,
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//make the request
$result = curl_exec($ch);
//this returns null
Any ideas where to go with this? Maybe I need to include the Cookies? I use
the above php and curl functions normally so it's all installed on the
server.

It might be that the site is using sessions/cookies. Have a look at
the header data with firebug.
Not sure if that's the problem, to find out what's really going on, call
echo curl_error($ch);
after curl_exec to find out what went wrong exactly.
If you still don't know how to proceed, paste the result of the
curl_error call in your reply.

I added the cookies to the post array. I changed php array to
"CACHED"=>array() for the JSON "CACHED":[], and corrected php's null to
NULL. It is not returning any error. The browser was showing 'resource
not present' before I added the cookies to the post array, now it just
returns null $result. Looks like I am transcribing something incorrectly.
