});

Fields hooks

Add custom field support:

add_filter('cpt_available_fields', function ($available_fields) {
    $available_fields['text'] = [
        'label' => __('Text', 'custom-post-types'),
        'fields' => [ // extra fields
            [
                'key' => 'placeholder',
                'label' => __('Placeholder', 'custom-post-types'),
                'info' => false,
                'required' => false,
                'type' => 'text',
                'extra' => [],
                'wrap' => [
                    'width' => '',
                    'class' => '',
                    'id' => '',
                    'layout' => ''
                ]
            ],
        ]
    ];
    return $available_fields;
});

In the example above the “text” field type support is added.

Manipulate the output of a custom field by type:

add_filter("cpt_get_field_type_{FIELD-TYPE}", function($output, $value, $post_type, $post_id){
    //
    // manipulates the $output
    //
    return $output;
}, 10, 4);

Manipulate the output of a custom field by id:

add_filter("cpt_get_field_{FIELD-ID}", function($output, $value, $post_type, $post_id){
    //
    // manipulates the $output
    //
    return $output;
}, 10, 4);

Manipulate the entered value of the custom field before saving:

add_filter("cpt_sanitize_field_{FIELD-TYPE}", function($input){
    //
    // manipulates the $input
    //
    return $input;
});

Templates hooks

Add blank template support to wrap type for your theme:

add_filter('cpt_themes_supports_rules', function ($supports_rules) {
    $supports_rules['twentytwenty'] = [
        'file-name' => 'singular.php',
        'replace-callback' => function ($content_to_replace) {
            $content_to_replace = str_replace("get_template_part( 'template-parts/content', get_post_type() )", 'custom_post_types_get_custom_template()', $content_to_replace);
            return $content_to_replace;
        },
    ];
    return $supports_rules;
});

In the example above the “Twenty Twenty” theme support is added, the necessary data are: theme folder name, path to the single template (file-name), callback to replace the default loop with the plugin function (replace-callback).

Settings fields

To avoid overwriting important settings that could damage your website database, the custom fields on the settings pages are stored by adding a suffix to the key.

For example, if you have created a field in the “Settings > General” page using the “text_field” key, you can retrieve that value using:

$field_value = get_option('general-text_field');

The prefixes to use based on where the custom field group has been assigned:

general–
writing-
reading-
discussion-
media-
