The value of name for the submit button is wrong - it should be the same
as the value you gave the isset statement, in this case it should be
<input type="submit" name="name" value="sendit">
Better yet is to use isset($submit) and the value for the submit
statement is also name="submit" -
<input type="submit" name="submit" value="sendit">
of course value is optional. So you end up with this -
<?
if (isset($_GET['submit']))
{
echo "Hallo ".$GET['name'];
}
else
{
echo "<FORM action='test.php' method=get>
<input type='text' name='name'>
<input type='submit' name='submit' value='sendit'>";
}
?>
