Answer 1

#if (Session::has('currency'))
$value = Session::get('currency');
#if(strcmp($value,"USD") == 0)
<input type="radio" name="currency" value="USD" checked id="usd">USD
<input type="radio" name="currency" value="AED" id="aed">AED
#else if(strcmp($value,"AED") == 0)
<input type="radio" name="currency" value="USD" id="usd">USD
<input type="radio" name="currency" value="AED" checked id="aed">AED
#endif
#else
<input type="radio" name="currency" value="USD" id="usd">USD
<input type="radio" name="currency" value="AED" id="aed">AED
#endif
I haven't used Laravel before, but just looking at a few off-site examples, you could try this. It should replace your current radio buttons.

You could save the states of the checkbox and pass them as POST by php or using javascript to set local storage
https://developer.mozilla.org/es/docs/Web/API/Storage/setItem
javascript:
//set the checkbox state
localStorage.setItem('checkbox_one','true');
localStorage.setItem('checkbox_one','false');
//on page load
if(localStorage.getItem('checkbox_one') == 'true'){
//checkbox was checked
}else{
//checkbox checked not true
}
