README

This class aims to facilitate the process of obtaining and sanitizing data from the post information (ID or object).

With MYC Getter, is possible to replace this:

$posts = [];
foreach ($query->posts as $post) {
  $genresObjects = get_the_terms($post, 'genre');
  $genres = [];
  if (is_array($genresObjects)) {
    foreach ($genresObjects as $genre) {
      $genres[] = [
        'name'      => esc_html($genre->name),
        'url'       => esc_url(get_term_link($genre)),
      ];
    }
  }

  $posts[] = [
      'title'     => esc_html($post->post_title),
      'url'       => esc_url(get_the_permalink($post)),
      'image'     => get_the_post_thumbnail($post, 'large'),
      'author'    => absint(get_field('author', $post)),
      'genres'    => $genres,
  ];
}

By this:

$args = [
  'acf'         => ['author' => 'string'],
  'taxonomies'  => ['genre' => 'link'],
];
$getter = new MycGetter($args);

$posts = [];
foreach ($query->posts as $post) {
  $posts[] = $getter->escapedContent($post);
}

Requirements

• PHP >= 8.0

Instalattion

composer require radishlab/myc-getter

Usage

use RadishLab\MycGetter\MycGetter;

class MyClass {
  public function MyMethod()
  {
    $getter = new MycGetter();
  }
}

The class accept two parameters:

1. $args
   • An array of arguments, listing the content you want to pull, or a preset name
   • If nothing is passed, the class will use the arguments of the preset default
2. $context
   • A string to identify where the class is being called
   • If nothing is passed, the class will use default

[
  'fields'        => ['title', 'url', 'image'],
  'image_size'    => 'large',
  'image_type'    => 'html',
  'acf'           => false,
  'taxonomies'    => false,
];

To overwrite the default preset, you just need to pass the keys you want to change:

$args = [
  'fields' => ['title'],
];
$getter = new MycGetter($args);

// The arguments used by the class will be:
[
  'fields'        => ['title'],
  'image_size'    => 'large',
  'image_type'    => 'html',
  'acf'           => false,
  'taxonomies'    => false,
];

If you're using the same arguments in multiples places, you can use the filter myc_getter_presets to create a new preset. Presets can also vary depend on $context:

add_filter('myc_getter_presets', function ($presets, $context) {
  $presets['new_preset'] = [
    'fields'    => ['title'],
    'image_size' => 'medium',
  ];

  return $presets;
}, 10, 2);

Then, you can use this new preset when instantiate the class:

$getter = new MycGetter('new_preset');

Modifying Settings After Instantiation

If you need to change the image size after creating the getter instance but before generating the image markup, you can use the setImageSize() method:

$getter = new MycGetter('my_preset');
$getter->setImageSize('thumbnail'); // Change from preset's image_size to 'thumbnail'

This method supports method chaining:

$getter = new MycGetter('my_preset');
$data = $getter->setImageSize('full')->escapedContent($post);
