Import Extern Image to Intern Page Image Field

[ocr_a]

Hello,

as mentioned here:

https://processwire.com/talk/topic/296-programmed-page-creation-import-image-from-url/?p=2016

i want to grab an image and save it on my server (for editing it later).

so here is my php. it's pretty easy, pt_embed_youtube is the video ID for a youtube video and i want to use it to grab the videos thumbnail and save it. pt_embed_youtube_pixel is an empty image field, which allows only 1 image. echo the content id is to make sure i am on the right page (this works fine).

if($content->pt_embed_youtube){
  echo $content->id;
  if(!$content->pt_embed_youtube_pixel){
    $content->of(false);
    $content->pt_embed_youtube_pixel = "http://img.youtube.com/vi/{$content->pt_embed_youtube}/1.jpg";
    $content->save();
  }
  echo "<img src='{$content->pt_embed_youtube_pixel->url}' alt=''>";
}

but i get this error and i really donot know what to do with it. is my server misconfigured, or did i miss some code or mixed it up?

Error: Exception: Unable to copy: http://img.youtube.com/vi/QxWbOZjxkA4/1.jpg => /kunden/238982_5020/webseiten/club/dev/site/assets/files/1030/1.jpg (in /kunden/238982_5020/webseiten/club/dev/wire/core/Pagefile.php line 107)

Looks like allow_url_fopen is disabled in your server's php settings, preventing file functions like copy or file_get_contents from working on URLs. If you can't change that setting, you could download the file manually into a temporary folder using curl and then assign the local path to the temp file (making sure the directory in $config->paths->tmp actually exists beforehand). A quick&dirty take:

// ...
        $localPath = download_file($content->pt_embed_youtube, $config->paths->tmp);
        $content->pt_embed_youtube_pixel = $localPath;
// ...

function download_file($url, $tempdir)
{
    $fp = $tempdir . basename(parse_url($url, PHP_URL_PATH));
    $fh = fopen($fp, 'wb');
    
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
    curl_setopt($curl, CURLOPT_FILE, $fh);

    curl_exec($curl);
    curl_close($curl);
    fclose($fh);
    
    return $fp;
}

Assuming BitPoet is correct and that is your problem, then it should work after that. Nothing wrong with doing it manually obviously, but just an FYI - there is a module for grabbing video images from YouTube/Vimeo and populating an images field, along with descriptions:

thanks both, it was the allow_url_fopen which was set to 0 instead of 1.

would be nice to have something like this (the php.ini settings connected to the api) in the documentary?! 

anyways, thanks again
