if statement problem

[ironman32]

I have had a reoccurrence of an if statement problem.

 

This if statement does not work if the user selects the value "yes".

 

if($_POST['medical'] = "yes"){
header("Location: acute.php?msg= Please consult your doctor before carring out these exercises");
die();
}

 

 

I'm not sure why this is because it looks ok to me. Can anyone shed some light on this?

One "=" for assignment, two "==" for comparison.

Also, you probably don't want to have your whole message in your URL, especially with spaces. Do something like "Location: acute.php?msg=3" and then in your page have it check for what the msg is via a switch statement:

 

switch($_GET['msg'])
{
    case 3:
    echo "Please consult your doctor before carring out these exercises";
    break;
}
//...etc
