default

This is used to set a default value for a variable. If the variable is unset or an empty string, the given default value is printed instead. Default takes the one argument.

Note: With error_reporting(E_ALL), undeclared variables will always throw an error within the template. This function is useful for replacing null or zero length strings.

Parameter Position	Type	Required	Default	Description
1	string	No	empty	This is the default value to output if the variable is empty.

Example 5-9. default


<?php

$smarty->assign('articleTitle', 'Dealers Will Hear Car Talk at Noon.');
$smarty->assign('email', '');

?>

Where template is:

{$articleTitle|default:'no title'}
{$myTitle|default:'no title'}
{$email|default:'No email address available'}

Will output:

Dealers Will Hear Car Talk at Noon.
no title
No email address available
