Laravel：如何从控制器传数组到Markdown邮件模板并循环渲染表格

Let's walk through fixing this step by step — the core issue is how you're processing the cart data in your controller and then looping through it in the email template.

Step 1: Fix the Controller's Cart Data Handling #

Your current code incorrectly tries to extract single values from the $panier array (which is a collection of multiple items). Instead, just pass the entire cart array directly to your Mailable class:

public function store(Request $request) {
    $phone = $request->phone;
    $email = $request->email;
    $address = $request->address;
    $panier = $request->panier; // This is already an array of cart items
    $total = $request->total;

    $data = [
        'phone' => $phone,
        'email' => $email,
        'address' => $address,
        'total' => $total
    ];

    if ($request){
        // Pass the full cart array to the Mailable
        Mail::to($email)->send(new SendInvoice($data, $panier));
    }
}

Step 2: Update the Mailable Class (Optional but Cleaner) #

You can adjust the variable name in your Mailable to be more intuitive (though this isn't strictly required):

class SendInvoice extends Mailable{
    use Queueable, SerializesModels;
    public $data, $panier;

    public function __construct($data, $panier) {
        $this->data = $data;
        $this->panier = $panier; // Use $panier instead of $data_panier for clarity
    }

    public function build() {
        return $this->from('noreply@mail.com', 'Mailer')
                    ->subject('New Order Confirmation')
                    ->markdown('mail.send-invoice');
    }
}

Step 3: Loop Through Cart Items in the Markdown Template #

Use Blade's @foreach directive to dynamically render each cart item as a table row. We'll also add a total row for clarity:

@component('mail::message')
# Your Order Confirmation

Hi there, here are the details of your recent order:

@component('mail::table')
| Product Name | Quantity | Price |
| ------------- |:-------------:| --------:|
@foreach($panier as $item)
| {{ $item['name'] }} | {{ $item['quantite'] }} | {{ $item['prix'] }} |
@endforeach
| **Order Total** | | {{ $data['total'] }} |
@endcomponent

@component('mail::button', ['url' => ''])
View Your Order
@endcomponent

Thanks for shopping with us,<br>
{{ config('app.name') }}
@endcomponent

Key Fixes Explained: #

• Controller: We stopped trying to split the cart array into individual fields — instead, we pass the full list of items directly to the email.
• Template: The @foreach loop iterates over each item in the $panier array, creating a table row for every product in the cart.
• Clarity: Renamed variables to be more readable, and added a formatted total row to the table.
