Correct. I create blocks in my templates for clearing out lists and other
bits of content that are only shown when certain criteria are met. I often
have 2 or 3 blocks in one part of the page when only 1 of them will ever be
shown at a time. To save parsing time, I do not declare the blocks I keep.

Extending upon my recent example:

***** sample.html *****

<!-- BEGIN show_employees -->
<table>
<tr>
	<th>Name</th>
	<th>Email</th>
</tr>
<!-- BEGIN employee -->
<tr>
	<td>{name}</td>
	<td><a href="mailto:{email}">{email}</a></td>
</tr>
<!-- END employee -->
</table>
<!-- END show_employees -->

<!-- BEGIN no_employees -->
I'm sorry, no records could be found.
<!-- END no_employees -->

***** /sample.html *****


***** sample.php *****

$t = new Template;
$t2 = new Template;

$t->set_file("content", "sample.html");
$db = new DB_MySQL;

$db->query("select name, email from employee order by name");

if($db->num_rows()) {
	$t->set_block("content", "employee", "employees");
	$t2->set_var("employee", $t->get_var("employee"));

	while($db->next_record()) {
		$t2->set_var($db->Record);
		$t2->parse("employees", "employee", true);
	}

	$t->set_var("employees", $t2->get_var("employees"));

	$t->set_block("content", "no_employees");
	$t->set_var("no_employees", "");
}
else {
	$t->set_block("content", "show_employees");
	$t->set_var("show_employees", "");
}

$t->parse("out", "content");
$t->pparse("out");

***** /sample.php *****
