Valid condition in blade form input

How to make valid condition for value tag in laravel 5.7 if field was modified and we have to show new value if field was modified ? I tried like that with required condition :

(old('common_settings_site_name') ? old('common_settings_site_name') : ( isset($common_settings_site_name) ?$common_settings_site_name : '' ) ),

it is good, bur not n case when field with existing value was cleared, then original value(not old - clear) is shown.

Like text field had some text “Value” The field was cleared. submitting form original field would be shown not empty string as I exepected ? How to fix it ?

Thanks!

Look at definition of old :

/**
     * Retrieve an old input item.
     *
     * @param  string  $key
     * @param  mixed   $default
     * @return mixed
     */
    function old($key = null, $default = null)
    {
        return app('request')->old($key, $default);
    }

You can use 2nd parameter for old method with your var.
