Laravel Teacher: Laravel

Laravel provides various in built tags to handle HTML forms easily and securely. All the major elements of HTML are generated using Laravel. To support this, we need to add HTML package to Laravel using composer.

Example 1

Step 1 − Execute the following command to proceed with the same.

composer require illuminate/html

Step 2 − This will add HTML package to Laravel as shown in the following image.

Step 3 − Now, we need to add this package to Laravel configuration file which is stored at config/app.php. Open this file and you will see a list of Laravel service providers as shown in the following image. Add HTML service provider as indicated in the outlined box in the following image.

Step 4 − Add aliases in the same file for HTML and Form. Notice the two lines indicated in the outlined box in the following image and add those two lines.

Step 5 − Now everything is setup. Let’s see how we can use various HTML elements using Laravel tags.

Opening a Form

{{ Form::open(array('url' => 'foo/bar')) }}
   //
{{ Form::close() }}

Generating a Label Element

echo Form::label('email', 'E-Mail Address');

Generating a Text Input

echo Form::text('username');

Specifying a Default Value

echo Form::text('email', 'example@gmail.com');

Generating a Password Input

echo Form::password('password');

Generating a File Input

echo Form::file('image');

Generating a Checkbox Or Radio Input

echo Form::checkbox('name', 'value');
echo Form::radio('name', 'value');

Generating a Checkbox Or Radio Input That Is Checked

echo Form::checkbox('name', 'value', true);
echo Form::radio('name', 'value', true);

Generating a Drop-Down List

echo Form::select('size', array('L' => 'Large', 'S' => 'Small'));

Generating A Submit Button

echo Form::submit('Click Me!');

Example 2

Step 1 − Copy the following code to create a view called resources/views/form.php.

resources/views/form.php

<html>
   <body>
      
      <?php
         echo Form::open(array('url' => 'foo/bar'));
            echo Form::text('username','Username');
            echo '<br/>';
            
            echo Form::text('email', 'example@gmail.com');
            echo '<br/>';
     
            echo Form::password('password');
            echo '<br/>';
            
            echo Form::checkbox('name', 'value');
            echo '<br/>';
            
            echo Form::radio('name', 'value');
            echo '<br/>';
            
            echo Form::file('image');
            echo '<br/>';
            
            echo Form::select('size', array('L' => 'Large', 'S' => 'Small'));
            echo '<br/>';
            
            echo Form::submit('Click Me!');
         echo Form::close();
      ?>
   
   </body>
</html>

Step 2 − Add the following line in app/Http/routes.php to add a route for view form.php

app/Http/routes.php

Route::get('/form',function(){
   return view('form');
});

Step 3 − Visit the following URL to see the form.

http://localhost:8000/form

Step 4 − The output will appear as shown in the following image.
