# Air helper

[![Packagist](https://img.shields.io/packagist/v/digitoimistodude/air-helper.svg?style=flat-square)](https://packagist.org/packages/digitoimistodude/air-helper) [![Build Status for PHP 8.3](https://github.com/digitoimistodude/air-helper/actions/workflows/php8.3.yml/badge.svg)](https://github.com/digitoimistodude/air-helper/actions/workflows/php8.3.yml) [![Build Status for PHP](https://github.com/digitoimistodude/air-helper/actions/workflows/php.yml/badge.svg)](https://github.com/digitoimistodude/air-helper/actions/workflows/php.yml)

Air helper provides helpful functions and modifications for WordPress projects. All modifications are preferences of [Dude](https://www.dude.fi). The plugin is meant to be used with our [Air light](https://github.com/digitoimistodude/air-light) theme, but works just fine also without it.

## Please note before using

Air helper and Air light are used for **development**, so those update very often. By using these code bases, you agree that the anything can change to a different direction without a prior warning.

## Development workflow

1. Git clone the repository to your local machine
2. Create a fork
3. Create a new branch for each new feature (Height task ID for Dude staff)
4. Push your changes to your fork

### Release cycle workflow

1. Test changes thoroughly in multiple projects by symlinking the dev version of air-helper to the projects:

```bash
  # Project 1
  rm -rf /var/www/project1/content/plugins/air-helper
  ln -s /var/www/air-helper /var/www/project1/content/plugins/

# Project 2
  rm -rf /var/www/project2/content/plugins/air-helper
  ln -s /var/www/air-helper /var/www/project2/content/plugins/

# Project 3
  rm -rf /var/www/project3/content/plugins/air-helper
  ln -s /var/www/air-helper /var/www/project3/content/plugins/
  ```

2. Run `composer validate` to check if the composer.json is valid
3. After verifying that the changes work as expected, send a pull request to the original repository
4. Wait for review and merge

#### For Dude staff

5. Update versions in air-helper.php, package.json and CHANGELOG.md
6. Create a release on GitHub with the same version number as the one in the `air-helper.php` file
7. The release will automatically be published to Packagist

## Features

### Localization and Polylang support

Air helper adds fallbacks for widely used Polylang functions, so you can use those events if there's no Polylang or multilanguage support needed in project at the time. This saves heck lot of a time when client want's multilanguage support later on.

Refer to section below and [functions](#localization) to find out how to use translated strings.

#### Registering your strings

All strings needs to be registered in one `localization.php` file and passed to `air_helper_pll_register_strings` an an array.

Like this.
```php
add_filter( 'air_helper_pll_register_strings', function() {
  return [
    // General
    'General: Read more' => 'Read more',

// Footer
    'Footer: Back to top' => 'Back to top',
  ]
} );
```

#### REST API support for string translations

By default, the string translation functions like `ask__()` does not work as intended when run inside a REST request, because Polylang does not support it. You can enable support by setting a `lang` parameter to your REST request and enabling the feature with hook:

```php
add_filter( 'air_helper_pll_enable_rest', '__return_true' );
```

### Image lazyloading

Air-helper supports [tuupola/lazyload](https://github.com/tuupola/lazyload) (legacy), [vanilla-lazyload](https://github.com/verlok/vanilla-lazyload) (legacy) and [native-lazyload](https://caniuse.com/?search=lazy) (native, current). [Air-light](https://github.com/digitoimistodude/air-light) version prior 6.1.8 (2020-10-20) had support for lazyload.js provided by [tuupola/lazyload](https://github.com/tuupola/lazyload) which is still legacy-supported by air-helper, but no longer provided by [air-light](https://github.com/digitoimistodude/air-light) theme.

Refer to [functions](#image-lazyloading-1) to find out how to use image lazyloading.

### Disabled views

In most of the client projects there's no need for some views that WordPress creates automatically. Instead of caring about those, show 404 page.

Currently disabled views are:
- archives: tag, category, date, author
- other: search

Enable specific view back with filter `add_filter( 'air_helper_disable_views_{VIEW}', '__return_false' );` or all views with `remove_action( 'template_redirect', 'air_helper_disable_views' )`.

### Functions

#### Archive related
* `get_posts_array( $args, $return_key )` Get posts in key=>title array.
* `get_post_years()` Get years where there are posts published.
* `get_post_months_by_year( $year, $post_type )` Get months where there are posts in a specific year. Defaults to current year.

#### Checks
* `post_exists_id( $post_id )` Check if post exists by ID.
* `has_content( $post_id )` Check if post has main content. Defaults to current post id.

Fallback is optional. By default fallback is default featured image from theme settings.

Args is optional. Its an array that contains "fallback", "sizes" and "class". Class can be set to give the image tag a specific class, if not set no class will be given.

If you want to get lazyloading div or tag as a string, you may prefix functions with `get_`.
