"wp-scripts build" doesn't copy reneder callback php file from src to build folder if "render" property set in block.json metadata

[realthemes]

Description

I'm developing my custom block plugin using create-block script, when the turn came to render callback file I set "render" metadata in block.json file like it say in documentation: "render": "file:./render.php", I also place file render.php in block folder but when I try to compile plugin whith npm run build command, the render.php file doesn't copied to /build/my-block/ folder, actually rest of plugin are compiling normally the only problem is copying. Currently I forced to use special command to force copy PHP files to build folder

Step-by-step reproduction instructions

1. create block plugin with create-block
2. set "render": "file:./render.php" metadata in block.json
3. compile whith "npm run build"
4. there no render.php file in build folder

@realthemes, thank you for the report. What version of @wordpress/scripts do you have installed? #43917 added support for automatic copying of the file defined in the render field of block.json. As far as I can tell, the version should be greater than 24.0.0.

I see that you noted that you use Windows, so maybe there is something wrong with how paths are handled. @t-hamano, would be so kind to verify that?

@gziolo here is the version - "@wordpress/scripts": "^25.4.0", sorry I was need to say that I make my plugin from single block to multiple block plugin, currently I have src folder and inside it nested my blocks folders, but I'm pretty sure that there no problem, beqause: 1. my plugin are compiling and all blocks are working, 2. If I use $ wp-scripts build --webpack-copy-php command then PHP file are copied correctly.

As long as the PHP file's path is relative to block.json, then it should pick it up. I assume it is because you didn't report issues with JS and CSS.

I didn't know until now that if the path to render.php is defined in block.json, it is automatically copied 😅 I mistakenly thought that we needed to specify the --webpack-copy-php option in order to copy the PHP file containing render.php.

Indeed, on Windows OS, it appears that the PHP file paths defined in block.json are not being copied. Below are the test results. I would like to explore the cause of the problem.

On Windows11

Build a single dynamic block

• ❌ wp-scripts build: render.php file is NOT copied to the build directory
• ✅ wp-scripts build --webpack-copy-php: render.php file and other PHP files are copied to the build directory

Build multiple blocks

• ❌ wp-scripts build: render.php file is NOT copied to the build/{block} directory
• ✅ wp-scripts build --webpack-copy-php: render.php file and other PHP files are copied to the build/{block} directory

On WSL2 (Ubuntu)

Build a single dynamic block

• ✅ wp-scripts build: render.php file is copied to the build directory
• ✅ wp-scripts build --webpack-copy-php: render.php file and other PHP files are copied to the build directory

Build multiple dynamic blocks

• ✅ wp-scripts build: render.php file is copied to the build/{block} directory
• ✅ wp-scripts build --webpack-copy-php: render.php file and other PHP files are copied to the build/{block} directory
