Anh - I found this code snippet and wondered if this could be modified to work with MB? Turns out that there is a third-party ACF addon that does the same thing...

add_shortcode('ss_screenshot', 'ss_screenshot_shortcode');
 function ss_screenshot_shortcode($atts){
  $width = intval($atts['width']);
  $width = (100 <= $width && $width <= 300) ? $width : 200;
  $site = trim($atts['site']);

if ($site != ''){
 $query_url =  'http://s.wordpress.com/mshots/v1/' . urlencode($site) . '?w=' . $width;
  $image_tag = '<img alt="' . $site . '" width="' . $width . '" src="' . $query_url . '" />';
 echo '<a href="' . $site . '">' . $image_tag . '</a>'; 
}else{

echo 'Bad screenshot URL!';
}
}

My guess is I would first have to create a special field type for this to work, so I would appreciate help with that too if this is possible.

Hi Neil,

This snippet creates a shortcode to include the screenshot of a site. It works anywhere, with any plugin. What do you want to do with that?

Hi Anh - it's been a while since opened this topic so I hope it's not too late to add to the thread...

the goal of the code snippet is to generate a screenshot from a URL entered into a form field.

Scenario - user enters data into a form that populates a custom template. the custom template displays the data collected in the form. one of the form fields is a URL field. in the custom template, instead of displaying only the URL field value (ex - https://google.com) as a text value, an actual screenshot of the URL is captured and displayed in the template.

here is the equivalent feature available for ACF Pro plugin - https://codecanyon.net/item/acf-website-screenshot/6280665

so, I'm hoping that this same feature can be worked into MB. thanks!

Hi Neil,

I think your code snippet in the first reply works pretty well. I modify it a little bit to creates a shortcode for showing website screenshot. It takes URL from a field.
```
add_action( 'init', function() {
    add_shortcode( 'screenshot', function( $atts ) {
        $atts = shortcode_atts( [
            'width'  => 300,
            'height' => 300,
            'field'  => 'website_url',
        ], $atts );
        $url = rwmb_meta( $atts['field'] );
        if ( ! $url ) {
            return '';
        }
        $query_url =  'http://s.wordpress.com/mshots/v1/' . urlencode( $url ) . "?w={$width}&h={$height}";
        $image_tag = "<img width='$width' height='$height' src='$query_url'>";
        return "<a href='$url'>$image_tag</a>";
    } );
} );
```
