Question

urlencode data for CURLOPT_POSTFIELDS in PHP?

Asked by: vkimura2007

Hi,

1) Just wondering if we're supposed to be urlencoding the data before submitting via CURLOPT_POSTFIELDS in PHP?

2) And am I supposed to use CURLOPT_COOKIEJAR option when I've already successfully logged in.

I'm having trouble posting. I can login successfully but I can't seem to post. Any ideas?

$postdata["pass"] = $pass;
        $postdata["id"] = $id;
        $postfields = generate_postfields($postdata);
        curl_setopt($ch, CURLOPT_URL, $url);
        //curl_setopt($ch, CURLOPT_REFERER, $referer);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
        curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // fake to be Internet Explorer 6.0
        //curl_setopt($ch, CURLOPT_COOKIEJAR, "/home/discoup9/public_html/curl/cookieFileName.txt");
        curl_setopt($ch, CURLOPT_COOKIEFILE, "/home/discoup9/public_html/curl/cookieFileName.txt");
        curl_setopt($ch, CURLOPT_POST, 1 );
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
        $result = curl_exec($ch);
        curl_close($ch);

HI,

Answer #1

You can either use array or a string to send the post data ($postfields).  If this $postfields is a query string then you should encode the url using urlencode() function. If its an array then its not required.


Answer #2

I used to set  CURLOPT_COOKIEFILE as well as CURLOPT_COOKIEJAR to maintain session between the pages. The cookie file path should be absolute, it may not work if the path is relative.


Also i got the below information (just i copied and pasted here)  from php.net  User contribution note.  Please give a try if above step not fix ur issue. (http://in.php.net/curl_setopt)

Sometimes you can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE becoz of the server php-settings(They say u may grab any files from server using these options). Here is the solution
1)Don't use CURLOPT_FOLLOWLOCATION
2)Use curl_setopt($ch, CURLOPT_HEADER, 1)
3)Grab from the header cookies like this:
preg_match_all('|Set-Cookie: (.*);|U', $content, $results);  
$cookies = implode(';', $results[1]);
4)Set them using curl_setopt($ch, CURLOPT_COOKIE,  $cookies);
