What goes wrong with my code?

seaminem

I think there's nothing wrong with my code, but the error message such as 'Please enter your name' does not appear on the screen when I submit the empty form. So...

1.Please help me figure out why the $ErrMsg does not appear on the screen.
2.If I want to join 2 conditions like if the $name and $surname is not empty, how to code it in PHP. I know that I have to use && but I can't write the correct structure.
3.Do I have to assign the new variable to keep the value when I have to use the variable as session_register?
Example: If the value in textbox is $name and I want to use it as session_register, do I have to assign $Newname= $name everytime?

Please....

Thank you so much! --> really mean it

========================================================

Here is my code:

$ErrMsg = ""; //initialized
if (!(empty($Submit)))
{ if (empty($Name))
$ErrMsg = $ErrMsg."Please enter your name. <BR>";
if (empty($Surname))
$ErrMsg = $ErrMsg."Please enter your surname. <BR>";

	if ($ErrMsg == "") //If all textboxes are filled, assign the values.
	{
		$EnterName = $Name;
		$EnterSurname = $Surname;
		include("Form3.php");
		exit;
	}
	else //print error
	{
		print $ErrMsg;
	}
   }

consider this example:

<?php
function form()
{
	$Name = '';
	$Surname = '';

if (isset($_POST['Name'])) {$Name = $_POST['Name'];}
if (isset($_POST['Surname'])) {$Surname = $_POST['Surname'];}

echo '
<form action="" method="POST">
Name: <input type="text" name="Name" value="' . $Name . '"><br>
Surname: <input type="text" name="Surname" value="' . $Surname . '"><br>
<input type="submit" name="submit" value="submit">
</form>
';
}

if (!isset($_POST['submit']))
{
	form();
}
else
{
	$errors = array();

foreach ($_POST as $key => $value)
{
	$value = trim($value);
	$value = stripslashes($value);
	if (!$value) {$errors[] = $key;}
	$_POST[$key] = $value;
}

if ($errors)
{
	echo 'you have the following error(s):<br>';
	foreach ($errors as $value) {echo 'missing ' . $value . '<br>';}
	form();
}
else
{
	echo 'thank you ' . $_POST['Name'] . ' ' . $_POST['Surname'] . ' for filling out my form';
}
}
?>

It's too complex for my first ASM. The teacher will not accept this code. Thanx anyway for your help.
