Question

Radio box code:

<input
  type  = "radio"
  name  = "choice"
  value = "A" />Apples />

<input
  type  = "radio"
  name  = "choice"
  value = "B" />Oranges<br />

$choice=array("A"=>1.00, "B"=>0.80);
echo $choice["A"]; // will give me the value of 1.00
echo $choice["B"]; // will give me the value of 0.80

Given the code snippet above, is there anything wrong in terms of either the HTML radio box, the array or the choices?

Answer 1

Nope, that looks perfectly fine.
Except for the random /> after your Apples text, but I suspect this is a typo?

You may also want to consider this. Probably what you are heading towards? 🙂

<?php
$choices = array("A"=>1.00, "B"=>0.80);
if(in_array($_REQUEST['choice'], array_keys($choices))) {
    echo $choices[$_REQUEST['choice']];
}
else {
    echo "Invalid choice received!";
}
?>

This would be the code that receives your radio choice. It makes sure the choice is valid and then prints it.
