How to get Media URL with custom width and media protection hash using Scriban

Question

I need separate image fields for mobile and desktop and trying to render it using Scriban in picture tag as below.

Current Scriban code:

<picture>
     <source srcset="{{ i_item.MyMobileImage.media_url }}" media="(max-width: 767px)">
     <source srcset="{{ i_item.MyDesktopImage.media_url }}" media="(min-width: 768px)">
</picture>

Is there a OOTB way to get image url with specific width and media protection hash using Scriban? or Writing Scriban extension is the solution?

Answer 1

I don't think there is an ootb way to do this (yet). A small extension could help you here. Something like this (not tested):

public class MediaUrl : IGenerateScribanContextProcessor
{
    private readonly IContext context;

    public MediaUrl(IContext context)
    {
        this.context = context;
    }

    public void Process(GenerateScribanContextPipelineArgs args)
    {
        var url = new GetMediaUrl(GetUrl);
        args.GlobalScriptObject.Import("sc_fullmediaurl", (Delegate)url);
    }

    public string GetUrl(Item item, string field, string width)
    {
        var options = new MediaUrlOptions { ... };
        var url = MediaManager.GetMediaUrl(mediaItem, options);
        return HashingUtils.ProtectAssetUrl(url);
    }

    private delegate string GetMediaUrl(Item item, string field, string width);
}

Another option could be to use sc_execute and a responsive image variant. This way you use the ootb functionality of SXA to get responsive images instead of having 2 image fields.
