Use index.php instead of index.html in new WebGL template

We used to be able to use index.php files in our WebGL templates instead of just index.html. Right now I get an error "index.html doesn't exist" if I try to use index.php though.

There's an old thread that talks about some workarounds for this, but the .htaccess options I found didn't work for us anymore.

Unity, can you please re-enable .php extensions on WebGL templates?

For now we're just manually renaming index.html to index.php. Anyone have a better idea?

Thanks!

 

Can't use php with Unity 2020.3.0f1.

 

You can have PHP in the .html file then rename it in your build process:

Code (CSharp):

1. using System.IO;
2. // ...
3. if (File.Exists(path + "\\index.html")) File.Move(path + "\\index.html", path + "\\index.php");

I do the same thing and it's been working fine from 2019.x->2022.1

 

@polemical, BOOM--you're a genius. Thank you!!

 

You mean OnPostprocessBuild?
Then it would be a good idea to rename it forth from index.php to index.html OnPreprocessBuild.
Do you have a complete solution for this? If yes, please share.

 

Sure - a quick example for WebGL. Drop this into an Editor folder, customize then hit Tools->Build The Project.

Code (CSharp):

1. using System.IO;
2. using UnityEngine;
3. using UnityEditor;
4.  
5. public class CustomBuildProcessExample : MonoBehaviour
6. {
7. #if UNITY_WEBGL
8.   [MenuItem("Tools/Build The Project")]
9.   static void BuildMyWebGL()
10.   {
11.     // specify the output path, i.e.
12.     string path = "C:\\wamp64\\www\\yoursite\\yourproject\\yourbuildnumber"; // auto-generate your output path however
13.  
14.     // if you need to create a folder you can do it like this..
15.     if (!Directory.Exists(path)) Directory.CreateDirectory(path); // note, CreateDirectory expects the parent folder to exist
16.  
17.     // define the scenes you want to include..
18.     BuildPlayerOptions options = new BuildPlayerOptions
19.     {
20.       locationPathName = path,
21.       scenes = new string[] {
22.         "Assets/Scenes/WhateverScene.unity",
23.         "Assets/Scenes/AnotherSceneToInclude.unity"
24.       },
25.       target = EditorUserBuildSettings.activeBuildTarget
26.     };
27.  
28.     // if you want, pick the WebGL template (which you normally pick in Project Settings->Player->Resolution & Presentation)
29.     // note: templates are in your Unity Editor installation, i.e. \Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\WebGLTemplates\Default\
30.     PlayerSettings.WebGL.template = "APPLICATION:Default"; // for example, replace "Default" with "MyCustomTemplate", to use WebGLTemplates\MyCustomTemplate\
31.  
32.     // if you're using Addressables, you could configure them here, then call:
33.     // AddressableAssetSettings.BuildPlayerContent();
34.  
35.     // build your app/game..
36.     BuildPipeline.BuildPlayer(options);
37.  
38.     // then post-process whatever, i.e.
39.  
40.     // if you're reusing a folder that might still contain previous index.php, you can delete it like this
41.     if (File.Exists(path + "\\index.php")) File.Delete(path + "\\index.php");
42.    
43.     // and as noted in the previous post, rename whatever .html files to .php
44.     if (File.Exists(path + "\\index.html")) File.Move(path + "\\index.html", path + "\\index.php");
45.  
46.     Debug.Log("Result: " + path);
47.   }
48. #endif
49. }

 

@polemical, that's an excellent enhancement and worked perfectly for me. Thank you again!!
