Long time ago i coded any php so i'm not sure this is valid code, but maybe something like this?
<?php
function has( var , default ) {
if( isset( $_POST[var] )
return $_POST[var];
elseif( isset( $_SESSION[var] )
return $_SESSION[var];
else
return default;
}
?>
<input id="username" name="username" type="text" size="30" value="<?=has('username','Username');?>" />

I prefer heredoc (http://www.php.net/manual/en/language.types.string.php #language.types.string.syntax.heredoc),
You can set all the variables you need in the first part of the script and concentrate on the layout in the second part
without worrying of single or double quotes and using the graph parenthesis to enclose the variables.
<?php
$username = (isset($_POST['username'])) ? $_POST['username'] : (isset($_SESSION['username'])) ? $_SESSION['username'] : 'Username';
echo <<< EXAMPLE
<input id="username" name="username" type="text" size="30" value="{$username}" />
EXAMPLE;
?>

It is easier to perceive error than to find truth, for former lies on the surface and is easily seen, while the latter lies in the depth, where few are willing to search for it.
How can I put the php-code in an function?
