How to Insert a value to a hidden input in Laravel Blade?

In Laravel Blade templates, you can insert values into hidden input fields using Blade syntax or Laravel's Form helpers. Hidden fields are commonly used to store data like CSRF tokens, user IDs, or secret keys that need to be submitted with forms but should not be visible to users.

Basic Hidden Input with Blade Syntax

The simplest way is to use standard HTML with Blade template syntax

Route Setup

<?php
Route::get('hello', function () {
   return view('hello', ['mymsg' => 'Welcome to Tutorialspoint']);
});
?>

Basic Blade Template (hello.blade.php)

{{$mymsg}}

Welcome to Tutorialspoint

Adding Hidden Input with Dynamic Values

To add a hidden field with dynamic data, pass the value from your route and use Blade syntax

Updated Route

<?php
Route::get('hello', function () {
   return view('hello', [
       'mymsg' => 'Welcome to Tutorialspoint',
       'secretKey' => '123456'
   ]);
});
?>

Blade Template with Hidden Input

{{$mymsg}}
<form>
    <input type="hidden" value="{{$secretKey}}" name="key">
</form>

Welcome to Tutorialspoint

The hidden input field will be present in the HTML source but invisible to users

<input type="hidden" value="123456" name="key">

Using Laravel Form Helper

Laravel's Form helper provides a cleaner approach for creating hidden fields

<?php echo Form::hidden('secretkey', '878$54509'); ?>

This generates

<input name="secretkey" type="hidden" value="878$54509">

Complete Form Example

{{$mymsg}}

<?php echo Form::open(array('url'=>'/hello')); ?>
<?php echo Form::hidden('secretkey', '878$54509'); ?>
<?php echo Form::close(); ?>

Adding Attributes to Hidden Fields

You can add additional attributes like id or class to hidden fields

<?php echo Form::hidden('secretkey', '878$54509', array('id' => 'key')); ?>

Or using Blade syntax

<input type="hidden" value="{{$secretKey}}" name="key" id="secretField" class="hidden-data">

Conclusion

Hidden inputs in Laravel Blade can be created using standard HTML with Blade syntax or Laravel's Form helpers. Use {{$variable}} to insert dynamic values and always validate hidden field data on the server side for security.
