why isn't this POST form submitting properly via CURL?

[bitt3n]

I'm trying to submit a POST form in order to input a given location (eg United Kingdom), then visit another page on the same site to obtain price information for this location. (I have permission to use this price data.) I'm pretty sure I'm screwing up submitting the POST form somehow. If I display the output of the first call to curl_exec($ch) I get 'Object moved to here.' with a link to default.aspx. What's the best way to fix this?

 

<?php

// STEP 1. let's create a cookie file
$ckfile = tempnam ("/tmp", "CURLCOOKIE");
// STEP 2. visit the homepage to set the cookie properly
$ch = curl_init ("http://www.pret-a-beaute.com/ChangeSeason.aspx");
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt( $ch, CURLOPT_POSTFIELDS, 'Country="67"');
curl_exec ($ch);

curl_setopt ($ch, CURLOPT_POST, false);

/* STEP 3. visit cookiepage.php */
$ch = curl_init ("http://www.pret-a-beaute.com/Whatsnew.aspx?CategoryId=0&Direction=0&OrderBy=36&ViewAll=1&PageNo=1&TopCatAll=1&TableLookupStr=");
curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($ch);

echo($output);

?>

 

the form in question is

 

<form method="post" action="ChangeSeason.aspx" name="ChangeSeason">

    <table align=center width="100%"  border="0" cellspacing="5" cellpadding="0">

        <tr>

            <td align=left class="MAINTEXTBLACKsmall" style="padding-left:75px;">

                COUNTRY

            </td>

        </tr>

        <tr>

            <td align=center>

                <select name="Country" id="Country" class="selectbox" onchange="ChangeSeason.submit();"><option value=0>CHOOSE YOUR COUNTRY</option>
                    <option  value="67">United Kingdom</option>

                    <option selected value="66">USA</option>
            </select>

            </td>

        </tr>

    </table>
    
</form>

I figured it out, I should have established the second URL via curl_setopt() rather than curl_init(), which resets the cookie location etc
