当用户在 Laravel 中更新电子邮件地址时发送电子邮件激活（确认）链接

Question

How can I resend my activation account email to my user once the user update the email address.

Email address should not be changed in the db until user click on the confirmation link

following is my update function for an user in my usercontroller(only the function body included)

if($request->hasFile('propic'))
           {
                $this->validate($request, [
                    'name' => ['required', 'alpha','min:2', 'max:255'],
                    'last_name' => ['required', 'alpha','min:5', 'max:255'],
                    'mobile' => ['required', 'numeric','min:9','regex:/\+(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|4[987654310]|3[9643210]|3[70]|7|1)\d{1,14}$/'],
                    'email' => ['required', 'string', 'email', 'max:255', 'unique:users,email,'.$setting->id.''],
                    'propic' => ['required','image','mimes:jpeg,png,jpg,gif,svg','max:2048'],
                ],$request->all());

                $imageName = time().'.'.$request->propic->extension();  
                $request->propic->move(public_path('propics'), $imageName);
                $setting->propic=$imageName;
                $setting->name=$request->input('name');
                $setting->last_name=$request->input('last_name');
                $setting->mobile=$request->input('mobile');
                $setting->email=$request->input('email');
                $setting->update();
                return Redirect::back()->with('success',__('sentence.User updated successfully'));  
           }

and following is my update user form

@endif
                    <img src="/propics/{{$user->propic}}" alt="Profile Pic" id="profile_pic_display" class="mb-3">

Currently i'm sending activation link to user email when the user is registering, but I'm struggling to do it when an existing user is trying to update email address..

Answer 1

Your question isn't entirely clear because you're working in a box here and haven't given us the full picture. If the intention is to ensure that the email cannot unless they've activated , then re-send them the activation email and confirm the new address upon activation, then you're missing some logic here.

Any way that you look at it, you need to store a reference to what the email should be somewhere. Either a column, such as pending_email on the table, or it's own table, such as pending_changes for instance.

In your boot method of your User model you can watch for the updating event and dispatch a job from there to re-send the activation email and halt the change of the email address:

public static function boot() 
{
    parent::boot();

    static::updating(function ($model) {
        if ($model->isDirty('email') && $model->activated_at === null) {
            $model->email = $model->getOriginal('email');
            dispatch (new SendActivationEmail($model));
        }
    });
}

Now you can append to that updating event to see if they're activating and have a pending_email :

static::updating(function ($model) {
    if ($model->isDirty('activated_at') && $model->pending_email) {
        $model->email = $model->pending_email;
        $model->pending_email = null;
    }
});
