Functions Overview#

The Miva Empressa engine powers the core functionality of Miva Merchant, offering a robust suite of functions for string manipulation, file handling, time management, and more. These functions enable developers to extend the capabilities of templates and create dynamic, responsive storefronts.

This section introduces some of the most commonly used functions and their applications.

Key Functions#

gettoken#

The gettoken function splits a string into tokens based on a delimiter and retrieves the specified token.

Example: 

<mvt:assign name="g.list" value="'apples,oranges,bananas'" />
<mvt:assign name="g.first" value="gettoken(g.list, ',', 1)" />
<p>First Item: &mvt:global:first;</p>

Output: 

First Item: apples

glosub#

The glosub function replaces all occurrences of a substring within a string.

Example: 

<mvt:assign name="g.string" value="'Miva Merchant 9 is amazing!'" />
<mvt:assign name="g.new_string" value="glosub(g.string, '9', '10')" />
<p>Updated String: &mvt:global:new_string;</p>

Output: 

Updated String: Miva Merchant 10 is amazing!

substring#

The substring function extracts a part of a string based on a starting position and length.

Example: 

<mvt:assign name="g.full_string" value="'Welcome to Miva!'" />
<mvt:assign name="g.sub" value="substring(g.full_string, 11, 4)" />
<p>Extracted: &mvt:global:sub;</p>

Output: 

Extracted: Miva
