Warning: file_get_contents() alternative with curl

Hi,

we like ur plugin, but since some server security configurations, we have troubles, because

“Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0”

Located in
“File: /wp-content/plugins/fb-comment-share-for-woocommerce/frontend/fbc-class-frontend.php”

Please update to something like below, to look for _getter and prefer if available, the curl _getter:

function fbc_comment_count() {
global $post, $product;

$url = get_permalink($post->ID);
// Produce error:
// $filecontent = file_get_contents(‘https://graph.facebook.com/?ids=’ . $url);
// Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /kunden/506462_20537/webseiten/meine-wilde-wiese.de/wordpress/wp-content/plugins/fb-comment-share-for-woocommerce/frontend/fbc-class-frontend.php on line 142

if(function_exists(‘curl_init’)) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, ‘https://graph.facebook.com/?ids=’ . $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$filecontent = curl_exec($ch);
curl_close($ch);
} elseif(ini_get(‘allow_url_fopen’)) {
$filecontent = file_get_contents(‘https://graph.facebook.com/?ids=’ . $url);
}
// Itdah comments prop missing
$count = 0;
$json = json_decode($filecontent);
if(isset($json->$url->comments)) {
$count = $json->$url->comments; // Error, when no comment entered
}
// END itdah

$wpCount = get_comments_number();
$realCount = $count + $wpCount;
if ($realCount == 0 || !isset($realCount)) {
$realCount = 0;
}
return $realCount;
}

Also nice to have in plugin main file, woocommerce version hints, to compare in wordpress plugins page for compatibility:

Best regards,
Alex
