Question

$email_ids=  DB::table('users')->pluck('email_id');
$name  = DB::table('users')-> pluck('name');

foreach ($email_ids as $email_id ) {                
   Mail::send('mail', ['user' => $name ] , function ($message) use ($email_id) {
        $message->from('abc@xyz.com', 'ABC');
        $message->to($email_id)->subject("Welcome");
   });    
}

我想通过电子邮件向各个用户发送邮件。我在数组中得到$email_ids和$name。但是当我运行此代码时，我收到错误

htmlentities（）期望参数1为字符串，给定数组

当我用'user' => $name替换'user' => $email_id时。我跑得很成功。

当我发送邮件时，它应该像

Hello , $name(name of user)

谢谢

Answer 1

您的代码应该是： -

$users = DB::table('users')->get(); // get all users
foreach ($users as $user ) { 
   $name =  $user->name; // get user's name
   $email_id =  $user->email_id; // get user's email
   Mail::send('mail', ['user' => $name ] , function ($message) use ($email_id) {
        $message->from('abc@xyz.com', 'ABC');
        $message->to($email_id)->subject("Welcome");
   });    
}

注意： - 您可以通过以下查询从数据库表中获取特定列，

$users = DB::table('users')->select('name', 'email_id')->get();

当视图文件中出现错误时，Laravel会显示htmlentities（）错误。

在您的情况下，您将在不同的阵列中获取姓名和电子邮件，但您只能预告public void attendence() throws SQLException{ employeelist = FXCollections.observableArrayList(); ename.setCellValueFactory(new PropertyValueFactory<Employee,String>("ename")); ecnic.setCellValueFactory(new PropertyValueFactory<Employee,String>("ecnic")); ebalance.setCellValueFactory(new PropertyValueFactory<Employee,Double>("ebalance")); etotalpaid.setCellValueFactory(new PropertyValueFactory<Employee,Double>("etotalpaid")); estatus.setCellValueFactory(new PropertyValueFactory<Employee,String>("estatus")); estatus.setCellFactory(ComboBoxTableCell.forTableColumn(new DefaultStringConverter(), attendenceoptions)); estatus.setOnEditCommit( new EventHandler<CellEditEvent<Employee, String>>() { @Override public void handle(CellEditEvent<Employee, String> t) { ((Employee) t.getTableView().getItems().get(t.getTablePosition().getRow())).setEstatus(t.getNewValue()); }; }); estatus.setEditable(true); stmt = conn.createStatement(); sql = "select * from employe"; rs = stmt.executeQuery(sql); while(rs.next()){ employeelist.add(new Employee(rs.getInt(1),rs.getString(2),rs.getString(3),rs.getDouble(5),rs.getDouble(6),"Present")); employeetable.setItems(employeelist); } stmt.close(); rs.close(); } }而不是$email_ids此行

$name

此

Mail::send('mail', ['user' => $name ] , function ($message) use ($email_id) {

中的

是按查询返回的名称数组，您将其打印为字符串，这就是为什么它会发出错误。

要实现您想要的更改代码

$name

获取错误为htmlentities（）期望参数1为字符串，给定数组
