How to do a background check only some of the fields in the form?

for example, there is in the admin panel, a few fields, username, email, password

But if I filled out the field password, then you need to check this field, and if the field is not filled, then no need to update the data in the database

how to do it?

You could write your validation rules with conditional statements:


if( $_POST['form_password'] )
{
    $val->add_field('password', 'Password', 'min_length[8]|max_length[64]');
}

Assuming you're used hand-coded forms, and only use a validation object, you can do it like this. But the if isn't really needed, as long as you don't put a required rule on it, it's ok if the value isn't there.

here is my html form ....

<?=\Form::label('Email', 'email', array('class' => 'control-label'))?>
<div class="controls">
<?=\Form::input('email', $user->email, array('required' => 'required'))?>
</div>
</div>

<div class="control-group">
<?=\Form::label('New password', 'password', array('class' => 'control-label'))?>
<div class="controls">
<?=\Form::input('password', null)?>
</div>

</div>

users controller

$val = Model_User::validate('edit');

if (\Input::method() == 'POST')
{
if ($user->email == \Input::post('email'))
{
$val->field('email')->delete_rule('unique');
}

if ($val->run(null, true))
{ ....

I know that you can do something like so

if ($val->run(array('password' => null), true))
{ ....

but if a lot of fields, may have some ability to disable the audited field

You can just add the field to the validation object. As long as you don't add the rule "required", it will pass if the value isn't posted.

If you have more complex forms, it's worth looking at fieldsets, which allows you to generate the form, and do built-in validation.
