如何在wordpress中保存碳字段的修订？

Question

我们正在使用WordPress网站中的自定义字段的碳域插件，但问题是WordPress不能存储碳自定义字段的修订。有人能帮上忙吗？

Answer 1

有两种方法可以在主题中包含碳场插件。1)在plugin文件夹中添加碳场插件并激活。2)在主题文件夹中添加碳域插件文件夹。

  /* Integrating Carbon Fields Plugin */
  use Carbon_Fields\Container;
  use Carbon_Fields\Field;
  add_action( 'after_setup_theme', 'crb_setup_theme' );
  function crb_setup_theme() {
      // check if Carbon Fields is not already installed
      if ( ! class_exists( "\\Carbon_Fields\\Field\\Field" ) ) {
          require( get_template_directory() . '/carbon-fields/carbon-fields-plugin.php' );
      }
  }
  add_action('carbon_register_fields', 'crb_register_custom_fields');
  function crb_register_custom_fields() {
      require get_template_directory() . '/theme_option/meta_boxes.php';
  }

在meta_boxes.php文件中，您需要创建元字段。像这样

    use Carbon_Fields\Container;
    use Carbon_Fields\Field;


    Container::make('post_meta', 'Date Container')                                                  // New Added
    ->show_on_post_type(array('hotel'))  // Hotel is custom post type
    ->add_fields(array(
            Field::make('complex','hotel_details_page_content', 'Images & Content')
            ->add_fields('Entry Container', array(
            Field::make("separator", "crb_image_options", "Image Entry"),
            Field::make("image", "row_images", "Image"),
            Field::make("text", "row_image_headlines", "Image Headline"),
            Field::make("text", "image_row_subheadlines", "Image Sub Headline"),
            Field::make("separator", "crb_style_options", "Content Entry"),
            Field::make("text", "content_titles", "Title"),
            Field::make("rich_text", "content_datas", "Content"),
        )),
    ));

    Container::make('post_meta', 'Gallery Container')
        ->show_on_post_type('gallery')  // Gallery is custom post type
        ->add_fields(array(
        Field::make('complex','galleryimages', 'Gallery')
            ->add_fields('Gallery Entry', array(
            Field::make("image", "gallery_images", "Upload Image"),
        ))
    ));

通过这种方式，您可以创建多个字段作为中继器，并且还可以保存值。

并在前端获取值。

$carbvalue= carbon_get_post_meta(get_the_ID(), 'hotel_details_page_content', 'complex');

foreach ($carbvalue as $carbonvalues) {
  $herorimageid  = $carbonvalues['row_images'];

  $heroimage = wp_get_attachment_url($herorimageid);
  ?>
    <img src="<?php echo $heroimage; ?>" sizes="100vw" alt="heroimage" />

  <?php 
  echo $carbonvalues['row_image_headlines'];
}
