gutenberg 块中的 setMeta 将元值保存在多行而不是一行

Question

我正在编写一个将数据保存到元字段中的古腾堡块。问题是该值被保存在数据库中的多行而不是一行中。如何保存一行？

例如：'My apple'保存为metakeyname:my和metakeyname:apple存入数据库。我想将它保存为 metakeyname: My apple

下面是我的代码。请帮忙。谢谢！

const { __ } = wp.i18n;
const { registerBlockType } = wp.blocks;
const { RichText, PlainText, MediaUpload, InspectorControls } = wp.editor;
const { TextControl, Tooltip, PanelBody, PanelRow, FormToggle, Button } = wp.components;
const el = wp.element.createElement;

registerBlockType('my/fields', {
    title: 'My Fields',
    description: 'Fill in the required data and press the Update button above',
    icon: 'products',
    category: 'common',
    attributes: {
        sku: {type: 'string'},
        
        pdf: {type: 'string'},
        gallery: {type: 'string'},
        features: {type: 'string'},
        brands: {type: 'string'},
        category: {type: 'string'},
    },
    
    edit: (props) => { 
    const { attributes, setAttributes } = props;
    const [meta, setMeta] = wp.coreData.useEntityProp('postType', 'post', 'meta');

        
return el(
  "div",
  null,
   el(
    "h3",
    null,
    "Please enter Product name above & details below"
  ),
   el(TextControl, {
    label: "SKU:",
    value: attributes.sku,
    onChange: (newtext) => setAttributes({ sku: newtext }) & setMeta({sku: newtext})        
  })
);
        
    },
    
    save: function(props) {
            return props.attributes.sku;
    }
    
})

我终于明白了。我必须定义 single = true 和类型，同时使特定字段在其余部分可用 api.

// Meta in REST API
add_action( 'rest_api_init', 'my_register_meta_fields');
function my_register_meta_fields() {
    register_meta( 'post', 'sku', array(
        'show_in_rest' => true,
        'single' => true,
        'type' => 'string',
    ));
}
