I tried brunekninja’s suggestion and several other autoload options in composer.json files for Bedrock, Sage, and Soil without success. I finally got this to work by loading the Foundation walker file on its own after Soil modules are loaded (and not including the Foundation walker in the Sage required files array). At the bottom of soil.php the modules are loaded with after_setup_theme, priority 100. So my Sage functions.php file now has this:
/**
* Sage required files
*
* The mapped array determines the code library included in your theme.
* Add or remove files to the array as needed. Supports child theme overrides.
*/
array_map(function ($file) use ($sage_error) {
$file = "../app/{$file}.php";
if (!locate_template($file, true, true)) {
$sage_error(sprintf(__('Error locating <code>%s</code> for inclusion.', 'sage'), $file), 'File not found');
}
}, ['helpers', 'setup', 'filters', 'admin']);
/**
* Foundation Nav Walker
*
* Load the Foundation nav walker after Soil plugin modules are loaded so that Soil's NavWalker class is available.
*/
add_action( 'after_setup_theme', 'add_foundation_nav_walker', 101 );
function add_foundation_nav_walker() {
if ( class_exists('\Roots\Soil\Nav\NavWalker') ) {
require get_template_directory() . '/../app/nav-foundation-walker.php';
}
}
I’m new to psr-4 and namespaces in php, but I gather that the reason for autoloading with psr-4 is to allow classes to be available independently of how they might otherwise be loaded via require, etc. Soil’s compser.json file currently doesn’t autoload anything. Should it include the following?
"autoload": {
"psr-4": { "Roots\\Soil\\Nav": "modules" }
},
When I try that and run composer update in Soil, the generated autoload file at soil/vendor/composer/autoload_psr4.php file correctly shows:
// autoload_psr4.php @generated by Composer
$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);
return array(
'Roots\\Soil\\Nav\\' => array($baseDir . '/modules'),
'Composer\\Installers\\' => array($vendorDir . '/composer/installers/src/Composer/Installers'),
);
But if I then load nav_foundation_walker.php via the Sage required array I still get “Fatal error: Class ‘Roots\Soil\Nav\NavWalker’ not found” when loading the site in my browser. I assume the correct way to do this is with autoloading, but I’m not sure how to make that work.
