Sending array within array in PHP cURL CURLOPT_POSTFIELDS

[isfak]

Hello!

 

I am trying to download a CSV file with the following curl:

$arrPostData = array(
'task' => 'download',
'selectedFields' => array('1', '2', '3') );

curl_setopt($ch, CURLOPT_URL, $strURL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($arrPostData));
$strCurlDownload = curl_exec($ch);

This curl unfortunately does not produce anything (nor fails with curl_errno).

Then I modify the $arrPostData array like that:

$arrPostData = array(
'task' => 'download',
'selectedFields' =>'1');

This works, but then I only get field 1 in the output CSV file. How can I modify the curl to be able to get all fields 1,2,3?

 

Thanks!

How does the service expect to receive multiple values of selectedFields? If it's not PHP style as "selectedFields[]=" then it's probably the more traditional style of using multiple "selectedFields=", which you'd have to build by-hand as PHP doesn't have a native function to do it for you.

curl_setopt($ch, CURLOPT_POSTFIELDS, "task=download&selectedFields=1&selectedFields=2&selectedFields=3");
