HTML scripts

How include the HTML-Scripts in my template, with a keyword?

_edit:_

the "html" script named my script: myCode

<?php
echo 'hello';
?>

in "index.php" I added
include("cutenews/snippet.php");

and into my template:

 $snippet = 'myCode'

Greetings

a. The initial purpose of snippets was to give users a possibility to change the content of web pages without using FTP. E.g. let's create a text snippet sandbox:

<?php
   require_once 'cn_api.php';
   $snippet = 'sandbox';
   include 'snippet.php';

On page test.php, for example.

Now, all the changes made by the admin to the data in snippets will will also be made to the contents of the test.php page.

b. If you write a structure in the form of [news|number=5] in the snippet, this will be equivalent to the inclusion of:

  <?php $number = 5; include "show_news.php"; ?> вместо [news|number=5].

Parameters can also be supplemented with, for example, [news | number = 5 | category = 1], and others.
