Laravel Helper Function: csrf_field

November 20, 2016 —John Koster

csrf_field()

The csrf_field function can be used to generate a hidden HTML element containing the value of the CSRF token. For example, the following HTML code can be greatly simplified using the function:

 1<!DOCTYPE html>
 2<html>
 3<head>
 4    <title>CSRF Token Form Sample</title>
 5</head>
 6<body>
 7    <form>
 8       <input type="hidden" name="_token"
 9              value="<?php echo csrf_token(); ?>">
10 
11       <!-- Other form inputs here -->
12    </form>
13</body>
14</html>

can be simplified to just:

 1<!DOCTYPE html>
 2<html>
 3<head>
 4    <title>CSRF Token Form Sample</title>
 5</head>
 6<body>
 7    <form>
 8       <?php echo csrf_field(); ?>
 9 
10       <!-- Other form inputs here -->
11    </form>
12</body>
13</html>

or with Blade syntax:

 1<!DOCTYPE html>
 2<html>
 3<head>
 4    <title>CSRF Token Form Sample</title>
 5</head>
 6<body>
 7    <form>
 8       {!! csrf_field() !!}
 9 
10       <!-- Other form inputs here -->
11    </form>
12</body>
13</html>
