我试图创建一个WordPress插件，其中将包括一些小的改进，我需要在我的博客块。我不是真的习惯了JSX /React语法，更不用说node.js，所以我试图做它写专门的PHP。
请看看我下面的代码，告诉我，如果我错过了什么，因为插件激活，但块不出现在编辑器中。

// dp_extensions-blocks.php 

include('dp_extensions-functions.php');

// Register a block to display the current time in any timezone

// Render the block
function dp_extensions__block_render__current_time($attributes) {
    $time = dp_extensions__functions__get_current_time($attributes);
    $html = '<p>' . $attributes['message_before'] . $time . $attributes['message_after'] . '</p>';
    return $html;
}

// Render the block in the block editor
function dp_extensions__block_edit__current_time($attributes) {
    $html = '<div class="dp-extensions-block-current-time">';
    $html .= '<label for="timezone">' . __('Timezone', 'dp_extensions') . ':</label>';
    $html .= '<input type="text" id="timezone" value="' . $attributes['timezone'] . '" onBlur="{ (value) => setAttributes({ timezone: value }) }" /><br />';

还有，有没有办法检测当前选择的块样式和其他块属性？get_block_attributes()函数似乎不可用，即使我尝试在设置为编辑回调函数的函数中使用它也是如此。
