[RESOLVED] Undefined Index and radio buttons

[focus310]

Hello:

I have a form which contains some radio buttons. For all the radio button fields, I receive an undefined index message.

I have looked and looked and I can't seem to find what is wrong. Can someone lend another pair of eyes and help me out?

Thanks in advance.

This is the code for the form.

<p><label for="mom_relation">Relationship:</label>
    <?php
      if($_SESSION['mom_relation'] == 'natural')
       echo '<input type="radio" name="mom_relation" id="mom_relation" value="natural" checked> Natural&nbsp;';
       else
       echo '<input type="radio" name="mom_relation" id="mom_relation" value="natural">Natural&nbsp;';

  if($_SESSION['mom_relation'] == 'step parent')
   echo '<input type="radio" name="mom_relation" id="mom_relation" value="step parent" checked> Step-Parent&nbsp;';
   else
   echo '<input type="radio" name="mom_relation" id="mom_relation" value="step parent">Step-Parent&nbsp;';

  if($_SESSION['mom_relation'] == 'adoptive')
   echo '<input type="radio" name="mom_relation" id="mom_relation" value="adoptive" checked>Adoptive&nbsp;';
   else
   echo '<input type="radio" name="mom_relation" id="mom_relation" value="adoptive">Adoptive&nbsp;';
 ?>
</p>

This is the code to validate the field.

if (!isset($_POST['mom_relation'])) {
    $errors[] = 'Please select a relation.';
   } else {
    $_SESSION['mom_relation'] = escape_data($_POST['mom_relation']);
   }

My guess is that $SESSION['mom_relation'] is not set, but it might help to see the actual error messages. Assuming that's the case, you would change the "if" lines in the form to something like:

if(!empty($_SESSION['mom_relation']) and $_SESSION['mom_relation'] == 'natural')

Hi,

Thanks for the reply. Apparently that was the problem. I was checking to see if the variable was first set.

Now everything is working as it should be so to speak. I have other issues I'm trying to get through now.🙂
