Answer 1

You can set most attributes by just passing them to the form helper so the following should work:

<?= $this->Form->input('mobile', [
    'class' => 'form-control reg_mobile_input',
    'label' => false,
    'oninvalid' => 'setCustomValidity(\'Without trailing zero\')',
    'pattern' => "^(?!0)[0-9]{10}$",
    'placeholder'=>'without initail zero'
    'required' => true,
]); ?>

See MDN docs on setCustomValidity for more on custom HTML error messages.
