form page layout

[luna_s]

finally got sessions working witout register globals being on - woo yay!

so how can a page be structured so that a single page exists to :-
1) enter data
2) check for omissions
3) reload same page with maybe highlighted missing fields
4) then put completed data into a mysql database

(just need a basic layout really - if else etc...)

currently i have a page that posts the data to a table in another page - i was thinking of trying to keep it all in one page (my form is currently an include btw)

ta much

[_SuperString]

maybe something like this.

// see if the form has been submitted
if(isset($_POST['submit'])) {
 $error = ""; //default value
 // check for errors
  if (isset($_POST['field'])) {
   .. more checking maybe

  } else {
    $error .=" the error here ";
   }

  if ($error != "") {
   // there was an error so show the message
  echo $message;
  } else {
     // no errors so add to database.
  }
} else {
  // show the form
  // with the method of post
  // an action to $PHPSELF
}

hope this helps you.
