Creare modelli di pagina personalizzati con i plugin?

get_page_template() puòessere sovrascrittotramiteilfiltro page_template. Seiltuoplugin è una directory coni modelli comefile al lorointerno,è solo questione dipassarei nomi di questifile. Se vuoi crearli "al volo" (modificarlinell'area di amministrazionee salvarlinel database?),Potresti volerli scriverein una directory della cachee fare riferimento a loro,o collegarli a template_redirect e fai unpo 'difolle eval() cose.

Un sempliceesempio diplugin che "reindirizza" a unfilenella stessa directory diplugin se un certo criterio è vero:

 add_filter( 'page_template', 'wpa3396_page_template' );
function wpa3396_page_template( $page_template )
{
    if ( is_page( 'my-custom-page-slug' ) ) {
        $page_template = dirname( __FILE__ ) . '/custom-page-template.php';
    }
    return $page_template;
}
 

get_page_template() can be overridden via the page_template filter. If your plugin is a directory with the templates as files in them, it's just a matter of passing the names of these files. If you want to create them "on the fly" (edit them in the admin area and save them in the database?), you might want to write them to a cache directory and refer to them, or hook into template_redirect and do some crazy eval() stuff.

A simple example for a plugin that "redirects" to a file in the same plugin directory if a certain criterium is true:

add_filter( 'page_template', 'wpa3396_page_template' );
function wpa3396_page_template( $page_template )
{
    if ( is_page( 'my-custom-page-slug' ) ) {
        $page_template = dirname( __FILE__ ) . '/custom-page-template.php';
    }
    return $page_template;
}

L'override di get_page_template () è solo un rapidotrucco. Non consente la selezione delmodello dalla schermata di amministrazionee lo slug dellapagina è hardcodednelplug-inin modo che l'utentenon abbiamodo di sapere da doveprovieneilmodello.

La soluzionepreferita sarebbe seguire questotutorial che consente di registrare unmodello dipaginanelback-end dalplug-in. Quindifunziona come qualsiasi altromodello.

        $this- >templates=array ();

        add_filter ('page_attributes_dropdown_pages_args',
            array ($this,'register_project_templates')
        );

//Aggiungi unfiltro almessaggio di salvataggioperinserireilmodellonella cache dellapagina
        add_filter ('wp_insert_post_data',

        );

//Aggiungere unfiltro all'inclusione delmodelloper determinare se lapagina hailnostro

        add_filter ('template_include',
            array ($this,'view_project_template')
        );

//Aggiungii tuoimodelli a questo array.
        $this- >templates=array (
                "goodtobebad-template.php"=> "Èbelloessere cattivi",
        );
}
 

Overriding get_page_template() is just a quick hack. It does not allow the template to be selected from the Admin screen and the page slug is hard-coded into the plugin so the user has no way to know where the template is coming from.

The preferred solution would be to follow this tutorial which allows you to register a page template in the back-end from the plug-in. Then it works like any other template.

 /*
 * Initializes the plugin by setting filters and administration functions.
 */
private function __construct() {
        $this->templates = array();

        // Add a filter to the attributes metabox to inject template into the cache.
        add_filter('page_attributes_dropdown_pages_args',
            array( $this, 'register_project_templates' ) 
        );

        // Add a filter to the save post to inject out template into the page cache
        add_filter('wp_insert_post_data', 
            array( $this, 'register_project_templates' ) 
        );

        // Add a filter to the template include to determine if the page has our 
        // template assigned and return it's path
        add_filter('template_include', 
            array( $this, 'view_project_template') 
        );

        // Add your templates to this array.
        $this->templates = array(
                'goodtobebad-template.php'     => 'It\'s Good to Be Bad',
        );
}

Sì,èpossibile.Hotrovatomolto utile questo plug-in diesempio .

Un altro approccio chemi è venutoin mente è l'utilizzo dell ' API WP Filesystem per creareilfile delmodelloperiltema.Non sono sicuro che sia l'approcciomigliore da adottare,ma sono sicuro chefunzioni!

Yes, it is possible. I found this example plugin very helpful.

Another approach that is come into my head is using WP Filesystem API to create the template file to theme. I am not sure that it is the best approach to take, but I am sure it work!

None of the previous answers was working for mine. Here one where you can choose your template in Wordpress admin. Just put it in your main php plugin file and change template-configurator.php by your template name

//Load template from specific page
add_filter( 'page_template', 'wpa3396_page_template' );
function wpa3396_page_template( $page_template ){

    if ( get_page_template_slug() == 'template-configurator.php' ) {
        $page_template = dirname( __FILE__ ) . '/template-configurator.php';
    }
    return $page_template;
}

/**
 * Add "Custom" template to page attirbute template section.
 */
add_filter( 'theme_page_templates', 'wpse_288589_add_template_to_select', 10, 4 );
function wpse_288589_add_template_to_select( $post_templates, $wp_theme, $post, $post_type ) {

    // Add custom template named template-custom.php to select dropdown 
    $post_templates['template-configurator.php'] = __('Configurator');

    return $post_templates;
}
