How would you check to see if a user selected one radio option over the other using PHP?

I'm a newbie when it comes to PHP and i've been trying to work with a radio button group where if a user selects Yes the form will relay a success message but if a user selects No a user will be redirected to an error page.

Code below:

PHP

//check to see if the child is not enrolled in school
//If the value of enrolled is No
if (isset($_POST["enrolled"]) ) {
  //redirects user to an error page.
  header("Location: /form-error.shtm");
}

HTML

<div>
  <form>
  <fieldset>
    <legend>
      <span>I am currently enrolled in high-school</span> 
    </legend>
    <div>
      <span>
        <input id="Yes" name="enrolled" type="radio" value="Yes" />
        <label>Yes</label>
      </span>
      <span>
        <input id="No" name="enrolled" type="radio" value="No" />
        <label>No</label>
      </span>
    </div>
  </fieldset>
  </form>
</div>

Solution

The issue is that on the PHP page, you are using a condition to see if $_POST["enrollment"] is set, but then you're not checking the value of the variable.

You should do this :

if (isset($_POST["enrollment"]) ) {
    if($_POST["enrollment"]==="Yes"){
         //success message
    }
    else{
      //redirects user to an error page.
      header("Location: /form-error.shtm");
    }
}
