Laravel 12.42 Highlights: HTTP Client Attributes, Enum Translator, Schema Index Checks

Laravel Framework 12.42.0 – Key Changes

HTTP client request attributes

Added withAttributes() to PendingRequest. Allows setting custom attributes that can be retrieved via attributes() on the response.

$response = Http::withAttributes(['name' => 'first'])
    ->get('https://example.com/test');

$attributes = $response->attributes(); // ['name' => 'first']

Enum support in Translator replacements

The Translator now accepts PHP enum values when performing placeholder replacements, enabling type‑safe translations.

$t = new Translator($loader, 'en');
echo $t->get('string_backed_enum', ['month' => Month::February]);
// Output: "Laravel 12 was released in February 2025"

Schema builder index helpers

Two new helpers whenTableHasIndex and whenTableDoesntHaveIndex simplify conditional index creation.

// Before
if (!Schema::hasIndex('product', 'name')) {
    Schema::table('product', function (Blueprint $table) {
        $table->index('name', 'index_name');
    });
}

// After
Schema::whenTableHasIndex('product', 'name', function (Blueprint $table) {
    $table->index('name', 'index_name');
});

// Specify index type
Schema::whenTableDoesntHaveIndex('product', 'name', function (Blueprint $table) {
    $table->index('name', 'index_name');
}, 'unique');
