Dropbox nested files download using CURL
Hi Support,
I am downloading files using below function where I am able to download only root files. I am facing issue in downloading files under folder
function dbx_get_file($token, $in_filepath, $out_filepath) { $out_fp = fopen($out_filepath, 'w+'); if ($out_fp === FALSE) { echo "fopen error; can't open $out_filepath\n"; return (NULL); } $url = 'https://content.dropboxapi.com/2/files/download'; $header_array = array( 'Authorization: Bearer ' . $token, 'Content-Type:', 'Dropbox-API-Arg: {"path":"' . $in_filepath . '"}' ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_HTTPHEADER, $header_array); curl_setopt($ch, CURLOPT_FILE, $out_fp); $metadata = null; curl_setopt($ch, CURLOPT_HEADERFUNCTION, function ($ch, $header) use (&$metadata) { $prefix = 'dropbox-api-result:'; if (strtolower(substr($header, 0, strlen($prefix))) === $prefix) { $metadata = json_decode(substr($header, strlen($prefix)), true); } return strlen($header); } ); $output = curl_exec($ch); if ($output === FALSE) { echo "curl error: " . curl_error($ch); } curl_close($ch); fclose($out_fp); return($metadata); } // dbx_get_file() if(isset($_GET['download'])) { $file = $_GET['download']; $metadata = dbx_get_file("token", '/'.$file, $file);
In above code when file under folder is passing for example 'test/abc.png' then it shows error in fopen() + unable to open file/folder.
Please help me to resolve this issue asap

It sounds like that's an issue with using `fopen` and not the Dropbox side of things, so I'm afraid I can't offer much help. You'll need to debug why you can't `fopen` your local file. (E.g., make sure the parent folders exist, that you have permission to access it, etc.)
