Not sure how to use curl with this particular variable
Hi,
I have a switch statement and in order for me to get a response, I have to include:
schemaVersion=3.0 in the request when the command is 'trims'. I don't have to when its 'makes' or 'models'. Just trims. The makes and models work just fine. But once I include the schemaVersion as a parameter in the url, it dies. Not sure I'm doing it right at all?
You can see my attempt below. It fails and the message is simply the foreach statement is crapping out.
I'm paranoid about the period in the 3.0, not sure if that is it?

case trims:
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS,"command=$command&year=$year&make=$make&model=$model&account=$account&key=$key&schemaVersion=3.0");
curl_setopt($ch,CURLOPT_RETURNTRANSFER , 1 );
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
$xml = new SimpleXMLElement($result);
foreach ($xml->Response->Trims->Trim as $trim) {
$data[] = $trim;
}
break;

Did you try passing value with single quotes?
I believe it is the 3.0. Even with curl, you should be 'urlencoding' your query parameters. I was just working on a Paypal problem and everything passed to curl gets urlencoded there.
See examples here: http://us3.php.net/manual/en/function.urlencode.php

Your right Ray, I'm not having an issue with 3.0.
I did what you suggested and it returned:
I think where I'm failing is how to iterate through. My foreach loop doesn't work:
$xml = new SimpleXMLElement($result);
foreach ($xml->Response->Trims->Tr
$data[] = $trim;
}
When I put that part of the code back in, the error is:
Warning: Invalid argument supplied for foreach() in /home/halifaxb/public_html
I did what you suggested and it returned:
string(287) "<?xml version="1.0"?>
<cbb xmlns="http://xml.blkbk.com/vehicle/3/0" schemaVersion="3.0">

<trims>
<trim id="213">GL</trim>
<trim id="217">GLS</trim>
<trim id="267">L</trim>
<trim id="281">Limited</trim>
</trims>
</response>

Hi, the var_dump helped me realize what the issue was: urlencode wasnt causing a problem, what was is the response and trims/trim were being returned in lowercase where makes, models and years were coming back capitalized for some bizarre reason.
I adjusted that and voila.

Glad it helped. Var_dump() is really my best friend!
