Puis-je utiliser des images personnalisées dans un thème wordpress (pas le mien)?

Question

Mon blog est développé par Altervista sur le thème ComicPress.

Je peux personnaliser mon site Web car j'ai acheté le domaine de deuxième niveau (.com).

J'essaie de publier de plus grandes images en suivant le tutoriel ci-dessous->

comment utiliser des images personnalisées dans un thème

Quelque chose a mal tourné depuis que j'ai copypasté le code et j'obtiens ce qui suit:

Erreur d'analyse: erreur de syntaxe, '<' inattendu dans /membri/thekrumbs/wp-content/themes/comicpress/functions.php à la ligne 40

J'ai copié/collé le code ci-dessous, tout comme je l'ai édité dans le fichier functions.php (voir la première partie) ->

<?php

add_action('after_setup_theme', 'comicpress_setup');

add_action( 'after_setup_theme', 'setup' );

    // To enable only for posts:
    //add_theme_support( 'post-thumbnails', array( 'post' ) );
    // To enable only for posts and custom post types:
    //add_theme_support( 'post-thumbnails', array( 'post', 'movie' ) );

    // Register a new image size.
    // This means that WordPress will create a copy of the post image with the specified dimensions
    // when you upload a new image. Register as many as needed.
    // Adding custom image sizes (name, width, height, crop)
    add_image_size( 'featured-image', 620, 200, true );


add_image_size( 'header', 600, 200, true ); // header image
add_image_size( 'custom-size1', 400, 200 ); // 400 pixel wide and 200 p
    add_image_size( 'custom-size2', 400, 200, true ); // 400 pixel wide and 200 pixel tall, cropped

Maintenant, j'ai modifié le fichier tel qu'il a été fourni à l'origine et je peux accéder à mon site à nouveau, mais je me demande pourquoi j'ai une telle erreur, à cause de problèmes de syntaxe ou parce que je suis sur un thème préconfiguré. Je vous demanderais donc:

Puis-je personnaliser complètement le thème de quelqu'un d'autre et modifier les fichiers pour utiliser des images personnalisées?

Answer 1

Erreur d'analyse: erreur de syntaxe, '<' inattendu dans /membri/thekrumbs/wp-content/themes/comicpress/functions.php à la ligne 40

<?php
if ( has_post_thumbnail()):
    the_post_thumbnail( 'featured-image', array( 'class' => 'featured-image' ) );
endif;
?>

Vous avez un bloc de code PHP, c'est-à-dire. <?php...?>, imbriqué dans un bloc de code PHP. Ce code semble hors de propos ici.

Answer 2

Oui, vous pouvez faire ce que vous voulez avec le thème que vous avez. Vous l'avez acheté (ou c'est gratuit).

Tant que vous l'avez acheté ou gratuitement, vous pouvez faire n'importe quoi. Assurez-vous simplement de créer un thème pour enfants à partir de votre thème. (Il existe des tutoriels pour cela sur wordpress community)

En effet, si vous (dans votre exemple) éditez functions.php sans créer de thème enfant, lorsque vous mettez à jour ce thème, votre fichier sera écrasé.
