如何在我的 laravel 9 項目中捕獲 MySQL/MariaDB 異常？

Question

在我的訂閱表單中，我將 email 字段作為 PK。 我想處理異常錯誤“SQLSTATE [23000]：完整性約束違規：1062 重復條目”。

我該怎么做？ PS：我插入到我的 Controller 內部的數據庫中

詢問：

if (isset($_POST['nom'], $_POST['prenom'], $_POST['email'], $_POST['cities'])) {
    $nom = request('nom');
    $prenom = request('prenom');
    $email = request('email');
    $ville = request('cities');
    DB::insert('insert into newsletter (nom, prenom, email, ville) values (?, ?, ?, ?)', [$nom, $prenom, $email, $ville]);
}

Answer 1

// put these at the top of the file with other imports
use Exception; 
use Illuminate\Support\Facades\Log;

try {
    DB::table('newsletter')->insert([
        'nom' => request('nom'),
        'prenom' => request('prenom'),
        'email' => request('email'),
        'ville' => request('ville'),
    ]);
} catch (Exception $exception) {
    // do whatever you want when exception happens
    Log::info($exception->getMessage());
}
