What potential challenges arise when creating individual templates for different page types in Smarty?

When creating individual templates for different page types in Smarty, a potential challenge is managing a large number of template files, which can become cumbersome to maintain. One way to solve this is by utilizing a template inheritance system, where common elements are included in a base template and specific elements are overridden in child templates.

// Base template file (base.tpl)
<html>
<head>
<title>{block name=title}Default Title{/block}</title>
</head>
<body>
{block name=content}Default Content{/block}
</body>
</html>

// Child template file (child.tpl)
{extends file='base.tpl'}
{block name=title}Child Page Title{/block}
{block name=content}Child Page Content{/block}
