Need to put processwire php inside a javascript string - Using Bablyon.js

[gbball]

<script>
//code
// Append glTF model to scene.
            BABYLON.SceneLoader.Append("<?php echo $config->urls->templates?>/glb/", "Silo.glb", scene, function (scene) {
                // Create a default arc rotate camera and light.
                scene.createDefaultCameraOrLight(true, true, true);
//code              
</script>              

I am trying to work with Bablylon.js to make a 3d comic on my Processwire site, but I need to pass a directory to the Bablylon scene loader inside of a string in the Bablylon Javascript function.

How do I tell Babylon to locate the file correctly while referencing Processwire's template directory through php?

Below is the documentation for the Bablylon Append method.

Static Append

Find examples in Playground

• Append(rootUrl: string, sceneFilename?: string | File, scene?: Nullable<Scene>, onSuccess?: Nullable<function>, onProgress?: Nullable<function>, onError?: Nullable<function>, pluginExtension?: Nullable<string>): Nullable<ISceneLoaderPlugin | ISceneLoaderPluginAsync>

<script>
//code  

<?php $glb = echo $config->urls->templates.'/glb' ?>       
            // Append glTF model to scene.
            BABYLON.SceneLoader.Append(<?php $glb?>, "Silo.glb", scene, function (scene) {
                // Create a default arc rotate camera and light.
                scene.createDefaultCameraOrLight(true, true, true);
  
//code
</script>  

Could something like this work?

You are missing an echo: <?php echo $glb?>

No big deal but "/" is not needed as the config value ends in that.

I don't know what the JS code does but generating bits of it with PHP should work ?

Thanks!  I'll give it a try!

Just one more thing I noticed in the code above: you do not need echo in this expression as assigning the ULR to the variable just works without it.

Got it working.  Thanks for the help!  I think I was overthinking it a bit, but since php is resolved first, it's okay to put the processwire tags inside a javascript argument.
