 10 | 
 11 | # Version 1.1.3 and below only
 12 | 
 13 | ## Installation 
 14 | 
 15 | **This is not a plugin**, you can just download the `class-katana.php`
 16 | or use composer to add it as a dependency in your website or plugin.
 17 | After you download the file make sure to include the file using `include` function.
 18 | 
 19 | In order to have access to the filters you need to create a new instance
 20 | of the Kata object.
 21 | 
 22 | ```php
 23 | $katana = new Katana();
 24 | ```
 25 | 
 26 | Also makes sure to inclode the file `class-katana.php` into your
 27 | `functions.php` file or in your plugin directory. After that you 
 28 | can add all your custom filters that you may require.
 29 | 
 30 | ## Usage
 31 | 
 32 | This library comes with custom filters that allows edit what sizes are
 33 | generated under some custom post types or under a specific `post_id`. 
 34 | 
 35 | **Note:** The default size of the image is always generated no matter
 36 | if you remove all sizes.  
 37 | 
 38 | ## Filters 
 39 | 
 40 | Each filter allow to return what sizes of images are needed for that
 41 | particular filter, the returned sizes represents the allowed images
 42 | sizes, each size is the name that was registered when you created an
 43 | image size using `add_image_size`.
 44 | 
 45 | ### katana_refine_{post_type}  
 46 | 
 47 | `{post_type}`, can be any post type declared on the site, post page or
 48 | even a custom one, like movies.
 49 | 
 50 | This filter allows to refine the sizes of images for a certain post
 51 | type.
 52 | 
 53 | **Example**
 54 | 
 55 | This example remove all the sizes from all of the pages, so any time you
 56 | add an image on a page it wont create any new size of image. 
 57 | 
 58 | ```php
 59 | add_filter('katana_refine_page', 'remove_all_sizes_from_pages');
 60 | 
 61 | function remove_all_sizes_from_pages( $sizes ){
 62 |   // Clear all the sizes of images
 63 |   $sizes = array();
 64 |   return $sizes;
 65 | }
 66 | ```
 67 | 
 68 | ### katana_refine_{post_id}
 69 | 
 70 | `{post_id}`, is the id of the post, page or custom post type all new
 71 | entries has a `post_id`
 72 | 
 73 | This filter allow you to change the required sizes on a particular
 74 | post_id all posts, pages or custom post types has a post_id than can be
 75 | used for this. 
 76 | 
 77 | **Example**
 78 | 
 79 | Imagine we have previously declared an `author_profile_image` size of
 80 | image, like:
 81 | 
 82 | ```php
 83 | add_image_size( 'author_profile_image', 350, 350, true );
 84 | ```
 85 | 
 86 | We need to creates images of the `author_profile_image` size only in the
 87 | entry with the id: `105`.
 88 | 
 89 | ```php
 90 | add_filter('katana_refine_105', 'allow_only_author_profile_image');
 91 | 
 92 | function allow_only_author_profile_image( $sizes ){
 93 |   $sizes = array( 'author_profile_image' );
 94 |   return $sizes; 
 95 | }
 96 | ```
 97 | 
 98 | ### katana_refine_{template_slug}
 99 | 
100 | `{template_slug}`,  is the slug of the template, the slug is where is
101 | located the template, replacing `-` and `/` by `_` and witout the `.php`
102 | extension. 
103 | 
104 | **Examples**  
105 | 
106 | | Location                    |     Filter name             |
107 | |-----------------------------|-----------------------------| 
108 | | page-templates/full.php     |     page_templates_full     |
109 | | page-templates/shop.php     |     page_templates_shop     |
110 | | portfolio.php               |     portfolio               |
111 | 
112 | **Example** 
113 | 
114 | This filter just allow to create two sizes of images in the
115 | `page-template/full.php`: 
116 | 
117 | - poster
118 | - landscape
119 | 
120 | ```php
121 | add_filter('katana_refine_page_templates_full', 'image_sizes_for_full_page_template');
122 | 
123 | function image_sizes_for_full_page_template( $sizes ){
124 |   $sizes = array( 'poster', 'landscape' );
125 |   return $sizes; 
126 | }
127 | ```

 10 | 
 11 | ## Previous version.
 12 | 
 13 | If you are using a version below 2, please make sure you take a look at
 14 | [the previous docs](readme-1.md) and if you are going to upgrade make
 15 | sure you follow the installation guide.
 16 | 
 17 | ## Installation 
 18 | 
 19 | **This is not a plugin**, rather is a library that can be used with your
 20 | own plugin or your theme. 
 21 | 
 22 | 1. You need to download the library using [composer](https://getcomposer.org/). In order to do this you can run the following command: 
 23 | 
 24 | ```bash
 25 | composer require mitogh/katana
 26 | ```
 27 | 
 28 | This will add the latest version of the library on your installation and
 29 | will create a vendor directory where the files are going to be located.
 30 | 
 31 | 2. If you are using a plugin or `functions.php` from a theme you only
 32 |    need to include the following file: 
 33 | 
 34 | ```php
 35 | include dirname( __FILE__ ) . '/vendor/autoload.php';
 36 | ```
 37 | 
 38 | That will allow you to use any filter from the class from `Katana` or
 39 | any other package installed via composer.  
 40 | 
 41 | That's practically all the process you need to follow in order to
 42 | install the library, since the library automatically creates the object
 43 | that is used for create the post and page filters.
 44 | 
 45 | ## Usage
 46 | 
 47 | This library comes with some filters that allows you edit what sizes of
 48 | images are generated under certain post types, page templates, post ID
 49 | or any other custom conditional.
 50 | 
 51 | ## Default size
 52 | 
 53 | As a note or reminder take into account that the default image size is
 54 | always generated even if you remove all image sizes with the filters.
 55 | 
 56 | ## Filters 
 57 | 
 58 | Each filter allow to return what sizes of images are needed for that
 59 | particular filter, the returned sizes represents the allowed images
 60 | sizes, each size is the name that was registered when you created an
 61 | image size using `add_image_size`.
 62 | 
 63 | By default Katana applies 3 filters in the following order: 
 64 | 
 65 | 1. Filter by post_id - priority 10
 66 | 2. Filter by post type - priority 20
 67 | 3. Filter by template page - priority 30
 68 | 
 69 | About filter priorities: 
 70 | 
 71 | > Used to specify the order in which the functions associated with a particular action are executed. Lower numbers correspond with earlier execution, and functions with the same priority are executed in the order in which they were added to the filter.
 72 | 
 73 | So if you are creating your own filter make sure to take priorities into account.
 74 | 
 75 | ### katana_refine
 76 | 
 77 | This is the filter triggered by Katana and is the one that you can use
 78 | to create custom conditionals or to create new filter names.
 79 | 
 80 | The filter sends two parameters, so you need to explicity specify the
 81 | number of arguments that are send to the filter: 
 82 | 
 83 | - `$sizes` An array with the sizes of the images availables on the site.
 84 | - `$id` The id of the post that triggers the filter.
 85 | 
 86 | For example you want to remove all the image sizes from a page that has
 87 | the title `tomacco`
 88 | 
 89 | ```php
 90 | add_filer( 'katana_refine', function($sizes, $id) {
 91 |     $title = strtolower( get_the_title( $id ) );
 92 |     if ( $title === 'tomacco' ) {
 93 |       return [];
 94 |     } else {
 95 |       return $sizes;
 96 |     }
 97 | }, 10, 2);
 98 | ```
 99 | 
100 | ### katana_refine_{post_type}  
101 | 
102 | `{post_type}`, can be any post type declared on the site, post page or
103 | even a custom one, like movies.
104 | 
105 | This filter allows to refine the sizes of images for a certain post
106 | type.
107 | 
108 | **Example**
109 | 
110 | This example remove all the sizes from all of the pages, so any time you
111 | add an image on a page it won't create a new size of image. 
112 | 
113 | ```php
114 | add_filter('katana_refine_page', '__return_empty_array');
115 | ```
116 | 
117 | The default two filters are: 
118 | 
119 | - `katana_refine_post`: Will allow you to update all the images
120 |   generated in all posts.
121 | - `katana_refine_page`: Allow you to change the default sizes generated
122 |   on all the pages.
123 | 
124 | Every time you create a new post type, you can use a new filter with the
125 | slug of the new post type.
126 | 
127 | ### katana_refine_{post_id}
128 | 
129 | `{post_id}`, is the id of the post, page or custom post type. (all new
130 | entries has a `post_id`)
131 | 
132 | This filter allows you to change the sizes on a particular `post_id`. (All posts, pages or custom post types has a post_id, than can be used with this filter).
133 | 
134 | **Example**
135 | 
136 | Imagine we have previously declared an `author_profile_image` size of an
137 | image, as follows:
138 | 
139 | ```php
140 | add_image_size( 'author_profile_image', 350, 350, true );
141 | ```
142 | 
143 | We need to creates images of the `author_profile_image` size only in the
144 | entry with the id: `105`.
145 | 
146 | ```php
147 | add_filter('katana_refine_105', 'allow_only_author_profile_image');
148 | 
149 | function allow_only_author_profile_image( $sizes ){
150 |   return array( 'author_profile_image' );
151 | }
152 | ```
153 | 
154 | ### katana_refine_{template_slug}
155 | 
156 | `{template_slug}`,  is the slug of the template, the slug is where is
157 | located the template, the template name is generated only with the last
158 | name of the template and removing the `.php` extension of that template
159 | file, some examples below:
160 | 
161 | **Examples**  
162 | 
163 | | Location                    |     Filter name             |
164 | |-----------------------------|-----------------------------| 
165 | | page-templates/full.php     |     katana_refine_full      |
166 | | page-templates/shop-page.php|     katana_refine_shop_page |
167 | | portfolio.php               |     katana_refine_portfolio |
168 | 
169 | **Example** 
170 | 
171 | This filter just allow to create two sizes of images in the
172 | `page-template/full.php`: 
173 | 
174 | - poster
175 | - landscape
176 | 
177 | ```php
178 | add_filter('katana_refine_full', 'image_sizes_for_full_page_template');
179 | 
180 | function image_sizes_for_full_page_template( $sizes ){
181 |   return array( 'poster', 'landscape' );
182 | }
183 | ```
