Create Custom laravel 8 rule to count the word of the request

Let’s use this command to generate a rule which helps to validate word count.

php artisan make: rule wordCount

This command will create the file at App/Rules with the name of wordCount.php and initially, it will contain the following code:

<?php
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
class WordCount implements Rule
{
/**
* Create a new rule instance.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Determine if the validation rule passes.
*
* @param string $attribute
* @param mixed $value
* @return bool
*/
public function passes($attribute, $value)
{
//
}
/**
* Get the validation error message.
*
* @return string
*/
public function message()
{
return “Your message here.”;
}
}

Copy and paste the following code for word count validation:

<?php
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
class wordCount implements Rule
{
/**
* Create a new rule instance.
*
* @return void
*/
private $attribute;
private $expected;
public function __construct(int $expected)
{
$this->expected = $expected;
}
/**
* Determine if the validation rule passes.
*
* @param string $attribute
* @param mixed $value
* @return bool
*/
public function passes($attribute, $value)
{
$this->attribute = $attribute;
$trimmed = trim($value);
$numWords = count(explode(‘ ‘, $trimmed));
return $numWords >= $this->expected;
}
/**
* Get the validation error message.
*
* @return string
*/
public function message()
{
return ‘The ‘.$this->attribute.’ field must have more than ‘.$this->expected.’ words’;
}
}

Now let's import the above rule in controller as :

use App\Rules\wordCount;

And finally used this validation with any request with any minimun length of the request as:

$request->validate([
‘introduction’ => [‘required’, new wordCount(50)],
]);

here the function wordCount accepts the dynamic argument like i used 50 as minimum wordCount for ‘introduction’ request.

Finally, use in blade as:

<textarea type=”text” name=”introduction” class=”form-control” rows=”4" placeholder=”{{translate(‘Introduction’)}}” required>{{ $member->member->introduction }}</textarea>
@error(‘introduction’)
@enderror

All done, now it will display the error if it does not satisfy the wordcount like

The introduction field must have more than 50 words.

Hopes it works for you.

HAPPY CODING!!

If you are a laravel developer you may run into the laraval.log permission error that is **The stream or file "log file location" could not be opened: failed to open stream: Permission denied. I found this error mostly while deploying laravel in VPS (virtual private network) in digitalocean droplet.

To solve this error there is only one command which is:

sudo chown -R www-data:www-data /var/www/{laravel_project_name}

Now your storage permission error must be solved by now.

Happy Coding!!
