Top 10 asked question-answer for new Laravel Developer


1. How to run a raw query in Laravel?

Answer: Laravel offers you Eloquent model and query builder to perform database query but sometimes we need to run a raw query because it makes our life easier rather than converting those raw queries into Eloquent query or query builder. To run a raw query in Laravel follow the example given below.

$sql = "select * from users u left join subscriptions s on u.id=s.user_id where s.subs_type='premium'";

$result = \DB::select($sql); 

Note: This example is a simple raw query which can be easily doable with eloquent query or query builder but the actual raw query can be more complex or bigger than it.


2. How to use a custom table name in the eloquent model?

Answer: If our eloquent model name is Post then Laravel will find a table in our database posts (which is plural name of our model name) but sometimes we need to change our table name with prefix name or something like that for security reason or our development strategy. That time we can easily set our table name in our eloquent model so that we don't have to change our model name according to our model name. See the given example below.

// model name Post and table name lp_post

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
   protected $table = 'lp_post';


3. How to disable created_at, updated_at field?

Answer: Laravel by default look for two columns in every table which created_at, updated_at. If these fields are not present in our table then laravel gives an error during data insertion or update. If we don't need these fields in our certain table we can tell laravel to ignore those fields. Let's check the example given below.

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Category extends Model
   public $timestamps = false;


4. How to remove public from URL?

Answer: For removing the public word from URL follow these steps given below.

  1. Move the index.php file from the public directory to root directory.
  2. Now open the index.php file and replace this line  require __DIR__ . '/../bootstrap/autoload.php'; to require __DIR__ . '/bootstrap/autoload.php'; and $app = require_once __DIR__ . '/../bootstrap/app.php'; to $app = require_once __DIR__ . '/bootstrap/app.php';
  3. Save and done! Keep in mind every time when you use any CSS, Js or image you have to add a public word in your asset helper function. Example: asset('public/css/style.css')


5. How to disable CSRF token in specific routes?

For security reason Laravel check CSRF ( Cross-Origin Resource Forgery)  token for every POST request. If you need to disable the CSRF token for specific routes then follow the steps given below.

  1. Open app\Http\Middleware\VerifyCsrfToken.php file.
  2. Now add those route path which you want to whitelist for CSRF token checking in the protected $except = [ ]



namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as Middleware;

class VerifyCsrfToken extends Middleware

    protected $addHttpCookie = true;
    protected $except = [


6. How to insert data by jQuery Ajax?

Answer: To send ajax post request for saving data, updating data or deleting. We need to send the _token field also for Laravel CSRF token checking validation. See the example given below.

In our HTML markup, we have to add a hidden field name with _token

<input type="hidden" name="_token" value="{{csrf_token()}}">

or use only CSRF blade directive


In our javascript part



	 	var _url = $(this).attr('action'),
	 		_type = 'POST',
	 		_data = $(this).serialize();

		    url: _url,
		    type: _type,
