yii2-sitemap-generator

Yii2 component for generate sitemap.xml files, _(*1)

Installation

Run, _(*2)

composer require "demi/sitemap-generator" "~1.0"

Configuration

Edit "/console/config/main.php", _(*3)

return [
    'controllerMap' => [
        'sitemap' => [
            'class' => 'demi\sitemap\SitemapController',
            'modelsPath' => '@console/models/sitemap', // Sitemap-data models directory
            'modelsNamespace' => 'console\models\sitemap', // Namespace in [[modelsPath]] files
            'savePathAlias' => '@frontend/web', // Where would be placed the generated sitemap-files
            'sitemapFileName' => 'sitemap.xml', // Name of main sitemap-file in [[savePathAlias]] directory
        ],
    ],
];

Because generator working in console, Yii create absolute url should know site base url, so configure it: "./environments/prod/console/config/main-local.php", _(*4)

'components' => [
    // fix console create url
    'urlManager' => [
        'baseUrl' => 'http://example.com',
    ],
],

"./environments/dev/console/config/main-local.php", _(*5)

'components' => [
    // fix console create url
    'urlManager' => [
        'baseUrl' => 'http://example.local',
    ],
],

The re-init project local config:, _(*6)

php ./init

OR just apply same config to your "/console/config/main-local.php", _(*7)

Also you can merge urlManager rules from frontend(or common) to console config.
Just change "/console/config/main.php" file:, _(*8)

// get config of urlManager from frontend for correctly create urls in console app
$frontend = require(__DIR__ . '/../../frontend/config/main.php');

return [
    'id' => 'app-console',
    'components' => [
        'urlManager' => $frontend['components']['urlManager'],
    ],
];

Also useful append .gitignore for ignore all generated sitemaps files:, _(*9)

# sitemaps
/frontend/web/sitemap*.xml

Sitemap-data models (important!)

You should create special sitemap-models for each your model, that should be in result sitemap.xml.
So let's create a maximal sitemap model extended from you Post model and attach interfaces:
/console/models/sitemap/SitemapPost.php, _(*10)

If you sitemap model doesn't have images or only one site language - just remove interfaces GoogleImage and/or GoogleAlternateLang and it's functions.
