Returning Form Variables

[craigerjs]

Hi, I have a user sign up form.  When some data is incorrect or missing it reloads the form, saving the info the user has already entered and displaying an error message for the parts that are invalid.  For example:

 

      <tr><td width = "300">      
      <label for="email">Email Address:</label></td>
      <td><input type="text" id="email" name="email" value="<?php if (!empty($email)) echo $email; ?>" /><br />
            </td></tr>

 

How can I return the submitted info for a checkbox and a birthdate?  Sorry, the birthdate code is kind of huge.

 

      <tr><td width = "300">      
      <label for="terms">I agree to the <a href = "/TOS.php">Terms of Service</a>.</label></td>
      <td><input type="checkbox" id="terms" name="terms" value = "checked"/><br />
            </td></tr>

To return the submitted in for selectbox, the code is like this.

 

<?php
function post($fieldname, $default = '')
{
  return isset($_POST($fieldname)) ? $_POST[$fieldname]:$default;
}
?>
<select name="DateOfBirth_Month">
  <option <?php echo post('DateOfBirth_Month')==1?'SELECTED':''?> value="1">January</option>
  <option <?php echo post('DateOfBirth_Month')==2?'SELECTED':''?> value="2">February</option>
</select>

<select id = "DateOfBirth_Day" name="DateOfBirth_Day">
   <option>Day</option>
<?php
for($i=1;$i<=31;$i++)
{
?>
	<option <?php echo post('DateOfBirth_Day')==1?'SELECTED':''?>value="<?php echo $i?>"><?php echo $i?></option>
<?php
}
?>
</select>

<select id = "DateOfBirth_Year" name="DateOfBirth_Year">
   <option>Year</option>
   <?php
for($i=2010;$i>=1900;$i--)
{
?>
	<option <?php echo post('DateOfBirth_Year')==1?'SELECTED':''?>value="<?php echo $i?>"><?php echo $i?></option>
<?php
}
?>
</select>
