I am working on saving images from external sites into a folder in my wordpress theme. And I was wondering if its Ok to call curl twice or can it be done with one time.
Example:
$data = get_url('http://www.veoh.com/watch/v19935546Y8hZPgbZ'); // getting the url first curl instance
preg_match('/fullHighResImagePath="(.*?)"/', $data, $thumbnail); // find the image from content
savePhoto($thumbnail, $post->ID); //2nd instance of curl to save the image
function get_url($url) {
$user_agent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2)";
$ytc = curl_init(); // initialize curl handle
curl_setopt($ytc, CURLOPT_URL, $url); // set url to post to
curl_setopt($ytc, CURLOPT_FAILONERROR, 1); // Fail on errors
curl_setopt($ytc, CURLOPT_FOLLOWLOCATION, 1); // allow redirects
curl_setopt($ytc, CURLOPT_RETURNTRANSFER, 1); // return into a variable
curl_setopt($ytc, CURLOPT_PORT, 80); //Set the port number
curl_setopt($ytc, CURLOPT_TIMEOUT, 15); // times out after 15s
curl_setopt($ytc, CURLOPT_HEADER, 1); // include HTTP headers
curl_setopt($ytc, CURLOPT_USERAGENT, $user_agent);
$source = curl_exec($ytc);
curl_close($ytc);
$data = trim( $source );
return $data;
}
function savePhoto($remoteImage, $isbn) {
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $remoteImage);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0);
$fileContents = curl_exec($ch);
curl_close($ch);
if (DIRECTORY_SEPARATOR=='/'){
$absolute_path = dirname(__FILE__).'/';
} else {
$absolute_path = str_replace('\\', '/', dirname(__FILE__)).'/';
}
$newImg = imagecreatefromstring($fileContents);
return imagejpeg($newImg, $absolute_path ."video_images/{$isbn}.jpg",100);
}
