使用laravel发送多个图像

Question

我想通过电子邮件发送多张图像。我是laravel的新手，我不知道如何添加多个附件。但是请采取以下方法。

发送电子邮件控制器：

foreach (json_decode($img_files) as $img_file) {
    $imgName = $img_file->name;
    $pathToFile[] = ['path' => public_path() . "\\uploads\\" . $imgName];
}

//send the email to the relevant customer email
Mail::to($customer_email)->send(new SendMail($customer_firstname, $pathToFile), function ($message) {
    // $message->attach($pathToFile);
    foreach ($pathToFile as $path) {
        $pathToFile = $path->path;

        $message->attach($pathToFile);
    }
});

dd（$ pathToFile）的输出

array:2 [
  0 => array:1 [
    "path" => "C:\xampp\htdocs\bit-project\public\uploads\photo_2019-11-08_23-11-50.jpg"
  ]
  1 => array:1 [
    "path" => "C:\xampp\htdocs\bit-project\public\uploads\photo_2019-11-08_23-11-55.jpg"
  ]
]

在电子邮件模板中，这是我添加图像的方式：

<img src="{{ $message->embed($pathToFile) }}" style="width:600px;height:335px">

如上所述，我有一个数组，其中包含上传的图像路径。我如何遍历此数组以将其传递给SendMail。感谢您的帮助！

（编辑）：这是SendMail类的代码

    public function __construct($customer_firstname, $pathToFile)
    {
        $this->customer_firstname = $customer_firstname;
        $this->pathToFile = $pathToFile;
        
    }

    public function build()
    {
       return $this->subject('Thank you! - Advance Car Diagnostics (Pvt.)Ltd')
                   ->view('admin.email_template')
                   ->with('data', $this->customer_firstname);
    }

我这样编辑了构建方法：

    public function build()
    {

        $email = $this->subject('Thank you! - Advance Car Diagnostics (Pvt.)Ltd')
                     ->view('admin.email_template')
                     ->with('data', $this->customer_firstname);

        foreach($this->pathToFile as $filePath){
            $email->attach($filePath);
    
        }
        return $email;
    }

但是它给出了这个错误：basename () expects parameter 1 to be string array

Answer 1

出现basename...错误的原因是在现在传递数组而不是文件名数组之前。

以下内容将帮助您实现所追求的目标：

$files = collect(json_decode($img_files))->map(function ($file) {
    return public_path('uploads' . DIRECTORY_SEPARATOR . $file->name);
})->toArray();

Mail::to($customer_email)->send(new SendMail($customer_firstname, $files));

SendMail类：

public function __construct($customer_firstname, $files)
{
    $this->customer_firstname = $customer_firstname;
    $this->files = $files;
}

public function build()
{
    return $this->subject('Thank you! - Advance Car Diagnostics (Pvt.)Ltd')
        ->view('admin.email_template')
        ->with('data', $this->customer_firstname); //I'm not sure if this line is correct but it's what you had in your question.
        ->with('files', $this->files);
}

admin.email_template：

@foreach($files as $file)
    <img src="{{ $message->embed($file) }}" style="width:600px;height:335px">
@endforeach
