如何在laravel中选择特定列

Question

I want to show all values of two specified columns 'first_name' and 'pic' from my 'users' table. I am trying 'pluck' but it showing like json format when echo. But I need to show it, something - 'John pic' for all.Please, someone help me. Here is my sample code in 'index.blade.php' bellow -

<?php
$fName = DB::table('users')->pluck('first_name','pic');

echo $fName;
?>

Answer 1

Use you can simply use select as

$fName = DB::table('users')->select('first_name','pic')->get();

Since, direct access to database from view is not preferred, you can write this query in controller function,

public function getData(){
    $fName = DB::table('users')->select('first_name','pic')->get();
    return view('index',compact('fName'));
}

Now, iterate over loop in view file,

@foreach($fName as $name)
    // access data like {{$name->first_name}} and {{$name->pic}}
@endforeach

Hope you understand.

You can use this code for retrieving specific column value:

//Eloquent: Get specific columns (not all the row). Pluck returns an array.
\App\Model::where('id', 1)->pluck('first_name','pic');
// If you only want to get the result value:
\App\Model::where('id', 1)->value('first_name');

You can get specific columns from a model using get() method, like

PostModel::where('post_status', 'publish')->get(['title', 'content', 'slug', 'image_url'])

pass the list of columns to get([...]) it will retrieve the modal data with specified columns.
