### FastAdminNet Template Layout and Block Definition

Source: https://github.com/fastadminnet/framework/blob/master/tests/application/views/extend2.html

This snippet demonstrates the basic structure of a FastAdminNet template file. It shows how to define a base layout using the 'layout' tag, create named content blocks with 'block' tags, include other template files using 'include', and use the 'literal' tag to render content without template parsing.

```Template Language
{layout name="layout2" replace="\[__REPLACE__\]" /} {block name="head"}{/block}

{include file="include" name="info" value="$info.value" /} {block name="main"} {block name="side"} side {/block} {block name="mainbody"} {/block} {/block} {literal} {$name} {/literal}
```

### Extending Layout and Defining Head Block in Template

Source: https://github.com/fastadminnet/framework/blob/master/tests/application/views/extend.html

This template snippet demonstrates the fundamental concepts of template inheritance and content block definition. The `extend` tag is used to specify a parent template ('extend2') from which the current template inherits its structure. The `block` tag defines a named section ('head') where specific content ('header') can be placed, allowing for modular and reusable page layouts.

```Template
{extend name="extend2" /} {block name="head"}header{/block}
```

### Including a Template File

Source: https://github.com/fastadminnet/framework/blob/master/tests/application/views/include.html

This snippet demonstrates how to include another template file, 'include2', into the current template. This mechanism is essential for reusing common components like headers, footers, or navigation bars across multiple pages, promoting modularity and maintainability in web development.

```ThinkPHP Template
{include file="include2" /}
```

### Display Variable with Default Value

Source: https://github.com/fastadminnet/framework/blob/master/tests/application/views/display.html

This snippet demonstrates how to safely display a variable's content within a template. It uses a null coalescing-like operator to check if the 'name' variable is set and not null. If 'name' is null or undefined, the string 'default' is rendered instead, preventing errors and ensuring a fallback display.

```Templating Language
{$name??'default'}
```
