Return Values

Hi all,

When i try to submit a form, and it returns that i forgot a field,

its will now return with

Code:

 header

function,
but then the fields are empty, what im trying to do is, if a field is empty, it will die()

i replaced the die() with header, so the page will open again and is not empty, but then the fields who were filled in, must now also be filled in....

any ideas?

the basic premise is like this (of course classes etc make this kind of thing a bit neater)

Code:

if (isset($_POST['submit'])){
   if (formValid()){
    processForm();
  } else {
    displayForm(true);
  }
} else {
  displayForm(false);
}

function formValid(){
 //check form submission validity
}

function processForm(){
 //process the incoming variables
}
function displayForm($sticky=false){
 $fields = array ('field1', 'field2');
 foreach ($fields as $field){
  if($sticky){
   $$field = '';
  else { 
   $$field = empty($_POST[$field]) ? '' : $_POST[$field];
   } 
 }
 echo <<<HTML
<form>
 <input type="text" name="field1" value="$field1" /><br/>
 <input type="text" name="field2' value="$field2" /><br/>
 <input  name="submit" value="submit" type="submit" />
</form>
HTML;
}

You could use session variables and just set value="<?=_SESSION['blah']?>"
