Photogallery

Omschrijving

This plugin is meant primarily for theme developers.

This plugin allows to collect photos from the the Media Manager and arrange them into albums.
These albums can be combined into galleries.
Both albums and galleries can be added to a theme’s navigation menu.

Note that this plugin does not provide any CSS formatting and JavaScript for frontend presentation of galleries and albums. You have to format them yourself and integrate necessary JavaScript libraries, e.g Lightbox, yourself. This plugin merely gives a framework for gallery and album creation via custom post types and registration of designs for a frontend presentation.

If you found a bug or have any questions, complains or suggestions please feel free to contact me.

Theme Integration

You have to write post type template files for your theme in order for an album or gallery to work.
This gives Theme developers the most control over a frontend presentation and users a convenient way to create galleries through the WordPress dashboard.
If you install this plugin, create albums and galleries and include them into your theme’s menu, you will be disappointed, since nothing will happen.

  1. Create two php files inside your theme’s directory: single-photogallery.php and single-photoalbum.php.
    • single-photogallery.php gets called everytime a gallery is about to be viewed
    • single-photoalbum.php gets called everytime a album is about to be viewed
  2. Now you have two options.
    • You can register a custom design inside your theme’s function.php via e.g $kt_Photogallery->register_gallery_design() and call $kt_Photogallery->render() at an appropriated place inside your single-photogallery.php to render it depending on the user’s choice.
    • You fetch albums, images and thumbnail details, and render consistent HTML for all albums and galleries.
  3. Refere to the PHP API section for further details on how to retrieve album IDs, image IDs and thumbnail details.

Example

A basic example for a custom gallery design

# functions.php

$kt_Photogallery->register_gallery_design ('my_gallery_design', array(
  'label' => __('My Gallery Design', 'my-textdomain'),
  'icon' => 'dashicons-format-gallery',
  'title' => __('This is my custom gallery design', 'my-textdomain'),
  'render' => 'render_my_gallery_design'
));

$kt_Photogallery->register_album_design ('my_album_design', array(
  'label' => __('My Album Design', 'my-textdomain'),
  'icon' => 'dashicons-format-image',
  'title' => __('This is my custom album design', 'my-textdomain'),
  'render' => 'render_my_album_design'
));

function render_my_gallery_design ($post) {
  global $kt_Photogallery;
  $album_IDs = $kt_Photogallery->get_albums($post);
  if ($album_IDs) {
    foreach ($album_IDs as $album_ID) {
      $album_thumbnail = $kt_Photogallery->get_thumbnail_src($album_ID);
      echo '<a href="' . get_permalink($album_ID) . '">';
      if ($album_thumbnail) {
        echo '<img src="' . $album_thumbnail[0] . '" alt />';
      }
      echo '</a>';
    }
  } else {
    printf(__('The gallery %s does not contain any albums', 'my-textdomain'), esc_html($post->post_title));
  }
}

function render_my_album_design ($post) {
  global $kt_Photogallery;
  $image_IDs = $kt_Photogallery->get_images($post);
  if ($image_IDs) {
    foreach ($image_IDs as $image_ID) {
      $image = get_post($image_ID);
      if ($image) {
        $image_src = wp_get_attachment_image_src($image_ID, 'medium');
        if (!$image_src) {
          $image_src = wp_get_attachment_image_src($image_ID, 'full');
        }
        echo '<img src="' . $image_src[0] . '" alt />';
      }
    }
  } else {
    printf(__('The album %s does not contain any images', 'my-textdomain'), esc_html($post->post_title));
  }
}

Basic integration into Twenty Fifteen:

# single-photogallery.php or single-photoalbum.php
get_header();
?>
<div id="primary" class="content-area">
  <main id="main" class="site-main" role="main">
  <?php
  while (have_posts()) {
    the_post();
    ?>
    <article class="hentry">
      <header class="entry-header">
      <?php
        the_title('<h1 class="entry-title">', '</h1>');
      ?>
      </header>
      <div class="entry-content">
      <?php
        $kt_Photogallery->render();
      ?>
      </div>
    </article>
    <?php
  }
  ?>
  </main>
</div>
<?php
get_footer();

Language & Translation

This plugin is in English (en_US) by default but comes with a German (de_DE) po-file.
There is also a pot file containing untranslated strings so you can use it if you wish to translate this plugin.
See also Using Localizations.
And especially WordPress – Poedit: Translation Secrets.

If you want your translation included in the next version of Photogallery, don’t hesitate and let me know.

  1. Get Poedit.
  2. Open the the pot file with Poedit and translate it.
  3. Save a copy as e.g kt-photogallery-fr_FR.po in /wp-content/plugins/kt-photogallery/language. The mo-file will be created automatically by Poedit if you ticked the checkbox in the preferences.

PHP API

I have included a number of functions for fetching album, image and thumbnail IDs associated with a gallery or album.
Please note that all methods starting with an underscore are considered internal and are not documented here. Although some are publicly accessible you should not use them directly unless you know what you are doing.

You do not have to create a new kt_Photogallery instance, there is already one in the global namespace.
Access all public methods via $kt_Photogallery.

  • $kt_Photogallery->get_album_count ( [$gallery_ID] )
    Returns the number of albums associated with a gallery
    Argument int|null $gallery_ID Optional – ID of a gallery. Defaults to the current ID if used inside the Loop
    Returns integer|boolean – Returns an integer on success, or false if $gallery_ID yields no gallery

  • $kt_Photogallery->get_albums ( [$gallery_ID] )
    Returns an array of album IDs associated with a gallery.
    Argument int|null $gallery_ID Optional – ID of a gallery. Defaults to the current ID if used inside the Loop

    Argument int|null $album_ID Optional – ID of an album. Defaults to the current ID if used inside the Loop
    Argument boolean $fallback Optional – if true and $album_ID yields no album the method returns the ID of the first image associated with the album. Default is true
    Returns integer|false – Returns an integer on success, false if $album_ID yields no album, no thumbnail is set or a fallback could not been resolved

  • $kt_Photogallery->get_thumbnail_src ( [$album_ID, [$fallback] ] )
    Returns an ordered array with values corresponding to the (0) url, (1) width, (2) height and (3) scale of the thumbnail associated with an album.
    Argument int|null $album_ID Optional – ID of an album. Defaults to the current ID if used inside the Loop

    The design will be available in the Design metabox during editing

    Argument string $key Required – A key used as id inside HTML/CSS and for general identification
    Argument callable|array $options Required – A callback rendering the design on the frontend or an associative array:

The arguments passed are the default options merged with the values from the current request, the default options as second argument and the current post as a WP_Post instance as third. The callback must return an associative array otherwise no options are stored.
  • $kt_Photogallery->render( [$auto_design] )
    Main output method. Depending on the current post type the method prints out a design for a gallery or an album.
    Argument boolean auto_design optional – If set true and no design is found, take the first registered one and proceed. Default is true
    Returns boolean – Returns true on success, false otherwise
