How to use

You can get and configure the instance of Fenom in any snippet.

For example, snippet Test:

Chunk Test:

And MODX call of snippet with chunk:

You will get Hello World!.

If you use this package as a dependency for your own extra, you can load and configure the instance inside your class and make it shared through all snippets to make the same settings and modifiers.

Template Providers

You have 3 template providers by default:

• MODX Chunk (default, no prefix - just specify id or name)
• MODX Template (template:1, or template:BaseTemplate)
• File (file:name.tpl)

If the MODX element has a static file, it will be used first, without checking the contents of the element in database.

File provider is native for Fenom, it makes no connection to database at all. Use it for maximum Fenom experience.

System Settings

All settings are prefixed with mmx-fenom..

elements-path

The root directory for File provider.

If it is not existing or not readable, provider will be disabled and you will get INFO record in MODX log.

By default, it is not existing core/elements directory.

options

JSON encoded string with options to override defaults of Fenom instance. For example:

See Fenom documentation for more information.

The default setting are:

use-php

You can enable the potentially dangerous use of PHP in templates with {$.php} accessor.

It will allow you to do anything with PHP, including deleting source files!

use-modx

You can enable the potentially dangerous use of MODX instance in templates with {$.modx} accessor.

It will allow you to access to everything in MODX, including deleting resources, elements and directories!

Modifiers

Feel free to use all the standard Fenom modifiers.

There are also 3 additional modifiers:

• print - print escaped variable, {$var | print}
• dump - dump escaped variable, {$var | dump}
• esc - escape MODX tags in variable, {$var | esc}

Accessors

You can access system accessors in your template:

• $.env to access $_ENV
• $.get to access $_GET
• $.post to access $_POST
• $.files to access $_FILES
• $.cookie to access $_COOKIE
• $.server to access $_SERVER
• $.session to access $_SESSION
• $.request to access $_REQUEST

For example {$.server | print}

Database Tables

This extra use 2 additional database table to store time of update of MODX chunks and templates, as they have no this data by default:

• mmx_fenom_chunks_time
• mmx_fenom_templates_time

Also, there is additional table for tracking migrations:

• mmx_fenom_migrations

Caching

When caching is enabled, you will get compiled templates in core/cache/mmx-fenom directory.

This directory will be deleted when you clear MODX cache.
