我只打印部门名称

Question

$dept_name = DB::table('departments')->select('dept_name')->where('id', '=', $request->alloted_dept)->get();
strong text**dd ($dept_name);

我想只打印部门名称，但在浏览器中显示 输出：

array:1 [▼
  0 => {#269 ▼
    +"dept_name": "IPS department"
  }
]

在echo $ dept_name上输出

ErrorException in abcController.php line 34: Array to string conversion

我想只输出“IPS部门”。

Answer 1

你必须循环你的结果

$dept_name = DB::table('departments')->select('dept_name')->where('id', '=', $request->alloted_dept)->get();

控制器

foreach($dept_name as $name) {
   echo $name;
}

视图

@foreach($dept_name as $name)
   {{ $name }}
@endforeach

Answer 2

我是这样做的：

$dept_name = DB::table('departments')->select('dept_name')->where('id', '=', $request->alloted_dept)->get();
$dept = "";
foreach($dept_name as $name) {
    $dept = $name->dept_name;
}
echo $dept;

输出：

IPS department
