如何将静态古腾堡块转换为使用 PHP 注册的动态块？

我正在尝试将我为 WordPress 创建的静态古腾堡块转换为动态块。我已经寻找其他解决方案，但没有成功。这个问题 （将使用 @wordpress/create-block 创建的静态 gutenberg 块转换为使用 PHP 注册的动态块的正确方法是什么？ https://stackoverflow.com/questions/70944838/what-is-the-correct-way-to-convert-a-static-gutenberg-block-created-using-wordp/71317657）与我正在寻找的非常相似，但我的静态块不是使用 @wordpress/create-block 制作的，在完成所有建议的步骤后，我看到了似乎是弃用问题的内容。

class-hello-tools-custom-blocks.php（注册块）

静态版本如下所示：

register_block_type( 'hello-tools/custom-cta', array(
    'style' => $this->plugin_slug . '-public',
    'editor_style' => 'hello-gutenberg-admin',
    'editor_script' => $this->plugin_slug . '-custom-blocks',
) );

动态变化如下：

register_block_type( __DIR__ . '/src/js/blocks/custom-cta/custom-cta-block.json', array(
    'style' => $this->plugin_slug . '-public',
    'editor_style' => 'hello-gutenberg-admin',
    'editor_script' => $this->plugin_slug . '-custom-blocks',
    'render_callback' => array( $this, 'hello_tools_custom_cta_callback' )
) );

同一插件文件中的回调函数如下所示：

public function hello_tools_custom_cta_callback( $attributes, $content ) {
    ob_start();
    require plugin_dir_path( __DIR__ ) . 'includes/partials/block-callbacks/hello-custom-cta-callback.php';
    $output = ob_get_contents();
    ob_end_clean();
    return $output;
}

custom-cta-block.json（定义块属性）

正如参考文献中所提到的register_block_type()上面，这是 block.json 文件。

我注意到渲染回调中无法在 JavaScript 中完成的主要函数是检查wpml_is_rtl and _icl_lang_duplicate_of。为此，使用 PHP/动态渲染来获取该值是有意义的。虽然，重写你原来的save()将函数导入 PHP，弃用前一个块，然后从 PHP 中的属性重置所有变量似乎并不理想。最终目标是相同的输出：渲染的 HTML。我在将现有插件迁移到 Gutenberg 块时遇到了类似的问题，您实际上只需要一点点 PHP 功能即可在最终标记中获得正确的逻辑。

替代方法：

注册您的块后，可以使用以下方法本地化块 JavaScriptwp_本地化_脚本 https://developer.wordpress.org/reference/functions/wp_localize_script/。这种方法的优点是您可以将值从 PHP 传递到 JavaScriptsave()而不必为了访问 PHP 函数而重写所有标记。

类-hello-tools-custom-blocks.php

// Revert to original static block
register_block_type( 'hello-tools/custom-cta', array(
    'style' => $this->plugin_slug . '-public',
    'editor_style' => 'hello-gutenberg-admin',
    'editor_script' => $this->plugin_slug . '-custom-blocks',
) );

// Localize script with an array (data) containing the values of PHP functions as needed
function hello_tools_localize_scripts()
{
    $id = get_the_ID(); // Changed from $post->ID in this context

    $is_rtl = (apply_filters('wpml_is_rtl', NULL)) ? true : false;

    if (is_object($post) && get_post_meta($id, '_icl_lang_duplicate_of', true)) {
        $is_rtl = false; // if this is on a duplicate page, keep the content LTR
    }

    // Name of script is santized name from block.json
    wp_localize_script('hello-tools-custom-cta', 'data', array(
        'is_rtl' => $is_rtl,
        'is_admin' => is_admin()
    ));
}
add_action('wp_enqueue_scripts', 'hello_tools_localize_scripts');

定制-cta.js

JavaScript 块现在可以访问data并使用其内容来保存所需的标记，例如：

save({ attributes }) {
   ...
   return (
       <div className={blockClasses}>
           {data.is_rtl && (
              // save something different for RTL
           )}
        ...
       </div>
   )
}
...

如果这是最初导致您切换到使用 PHP 渲染的原因，那么希望您可以实现上面的建议，删除hello-custom-cta-callback.php完全，并重用您现有的save()带有附加变量的函数。

另请检查您的先前版本custom-cta-block.json了解之前如何定义您的属性。为了属性 https://developer.wordpress.org/block-editor/reference-guides/block-api/block-attributes/可编辑的<RichText ../>，该值可以来自保存的标记 - 您可以使用类选择器设置源，例如：

"attributes" :{
    ...
    "blurb": {
        "type": "string",
        "source": "text",
        "selector": ".hello-custom-cta__blurb",
        "default": ""
    },
...
}
