Add the correct HTML attributes to the form helper

Does anyone have time for a little change?
It would be correct for the form helper to set the attributes "required",  "disabled",  "autofocus", "readonly"
Basically it's boolean values output as 

Code:

<input type="text" required disabled autofocus readonly>

I think it's worth adding this feature to parse_form_attributes() function.
What for? It is not possible to easily set these options in form_input(), form_textarea(), etc.
Empty values are inserted. For HTML 5 this is wrong

PHP Code:

form_input([
  'name' => 'datebirth',
  'value' => set_value('datebirth', $dateBirth),
  'class' => 'form-control',
  'type' => 'date',
  'disabled' => empty($dateBirth) ? false : true,
  'required' => false,
  'readonly' => false
])
// <input type="date" name="datebirth" value="" class="form-control" disabled="" required="" readonly="">

I would gladly review a Pull Request from you

I had no experience in open source support 

If no one does it, I'll try it later

It seems this is already fixed.

PHP Code:

<?php

namespace App\Controllers;

class Home extends BaseController
{
    public function index()
    {
        helper('form');
        echo esc(form_input([
            'name'    => 'datebirth',
            'value'    => '',
            'class'    => 'form-control',
            'type'    => 'date',
            'required' => false,
            'readonly' => false,
        ]));
    }
} 


I see

Code:

<input type="date" name="datebirth" value="" class="form-control" required readonly />

Wait, 'required' => false makes outputting required?

It seems no problem as HTML:

PHP Code:

form_input([
  'name' => 'datebirth',
  'value' => set_value('datebirth', $dateBirth),
  'class' => 'form-control',
  'type' => 'date',
  'disabled' => empty($dateBirth) ? false : true,
  'required' => false,
  'readonly' => false
])
// <input type="date" name="datebirth" value="" class="form-control" disabled="" required="" readonly=""> 


Cannot reproduce this.

It seems the feature to show boolean attributes has been since v4.0.0.
