Help with form

freedom1804

I am working on a registration form. Everything looks fine except for if a person fills out the form and misses something, when it takes them back to the from to complete, some of the information that was already there gets dropped i.e. the number of their address is there but the street address gets dropped.

How can I fix this?

Don't send people back. Instead print the form once again, populating fields with data from $_POST.

Thank you very much!
Now i have a field of the form created through php as ----echo("<input name='address' size='40' type='text' value=$city>");----how do i use the $_post function to make the variables pass through it?

A simple example of what I mean:

<?php
 if (isset($_POST['posted']))
 {
  $correct = true;
  //check if all is right
  if (trim($_POST['city'])=="")
  {
     echo "You haven't filled in City field.<br>";
     $correct = false;
  }
  if (trim($_POST['country'])=="")
  {
     echo "You haven't filled in Country field.<br>";
     $correct = false;
  }

  if (!$correct)
  {
     print_form($_POST['city'],$_POST['country']);
  }
  else
      echo "All data OK!";
 }
 else
     print_form("","");

//function definition
function print_form($city, $country)
{
 echo <<<END
 <FORM ACTION="$_SERVER[PHP_SELF]" METHOD="POST">
 <INPUT TYPE="hidden" NAME="posted" VALUE="posted">
  City: <INPUT TYPE="TEXT" NAME="city" VALUE="$city"><br>
  Country: <INPUT TYPE="TEXT" NAME="country" VALUE="$country"><br>
  <INPUT TYPE="SUBMIT" VALUE="Send">
</FORM>
END;
}
?>
