Vdlp.RssFetcher

Fetches RSS/Atom feeds to put on your website. It can be automated using a cronjob or triggered manually.

Installation

composer require vdlp/oc-rssfetcher-plugin

RSS & Atom feeds

The plugin uses the laminas/laminas-feed package to parse the RSS and/or Atom feeds. For more information on this package goto https://docs.laminas.dev/laminas-feed/

Components

The plugin is configured with 4 example sources and has a few components which help you to display items and/or sources on your website.

Items

Shows a list of most recent RSS items limited on the maximum number of items provided by you.

An example of implementation code in your CMS page:

title = "A list of items"
url = "/items"
layout = "default"
is_hidden = 0

[rssItems]
maxItems = 10
==
{% component 'rssItems' %}

PaginatableItems

Shows a list of most recent RSS items with an additional paginator element.

An example of implementation code in your CMS page:

title = "A list of items (paginatable)"
url = "/items"
layout = "default"
is_hidden = 0

[rssPaginatableItems]
itemsPerPage = 3
==
{% component 'rssPaginatableItems' %}

Sources

Shows a list of sources.

An example of implementation code in your CMS page:

title = "A list of sources"
url = "/sources"
layout = "default"
is_hidden = 0

[rssSources]
==
{% component 'rssSources' %}

Events

To manipulate RSS items there are a few events which can be used:

• vdlp.rssfetcher.item.processTitle
• vdlp.rssfetcher.item.processContent
• vdlp.rssfetcher.item.processLink

Use them like this:

Event::listen('vdlp.rssfetcher.item.processTitle', function (&$title) {
    $title = $title . 'A';
});

Event::listen('vdlp.rssfetcher.item.processContent', function (&$content) {
    $content = strip_tags($content);
});

Reporting Widgets

This plugin contains also a RSS Headlines widget to show the latest headlines on your Dashboard. This widget has three configurable properties: maxItems, title and dateFormat.

Cronjob

There are many ways to configure a cronjob. Here's a basic example of cronjob configuration line:

5/* * * * php path/to/artisan vdlp:fetch-rss >> /dev/null 2>&1

The above line takes care of fetching all sources every 5 minutes.

The vdlp:fetch-rss command takes an optional source_id argument. Provide the source ID if you want to fetch only 1 source at that time.

Execute from code

In your plugin code you can also use the following code to execute the Artisan command:

<?php

use Artisan;
// ...

Artisan::call('vdlp:fetch-rss', ['source' => 2]);

Or using the RssFetcher singleton:

RssFetcher::instance()->fetch(2);
