私は何日もこれを理解しようとしてきました。画像をアップロードし、正方形にトリミングし、300x300 にサイズ変更してから、150x150 にサイズ変更し、「uploads/products/$id/」フォルダーにアップロードしてから、ファイルパスを mysql データベースに押し込む必要があります。
ただし、黒い画像が出力され続けます。このスクリプトの何が問題になっていますか?
$ext = explode('.', $_FILES['image1']['name']);
$extension = $ext[1];
$target_path = 'uploads/products/'.$id.'/';

$featured100_full_path = $target_path.$filename;
if(!is_dir('../../../uploads/products/'.$id)){
mkdir('../../../uploads/products/'.$id, 0777);
}

chmod('../../../'.$featured100_full_path, 0755);
