wordpress - 防止 wp.hooks.addFilter() 在古腾堡中的某些自定义帖子类型上运行

我的任务是防止 addFilter() 使用新的 Gutenberg API 而不是任何 WP PHP 在某些自定义帖子类型上运行。它当前被输入到 editor.PostFeaturedImage 钩子(Hook)中，这意味着每次古腾堡编辑器加载特色图像框时它都会触发。

过滤器调用一个函数，在特色图像框下方添加一个下拉菜单，以允许用户选择贡献者(它们本身是自定义的帖子类型)以将图像归功于。

过滤器不应在贡献者自定义帖子类型上运行，而应在其他自定义帖子类型上运行。贡献者自定义帖子类型仍然应该有一个特色图片框，但没有下拉菜单。

让钩子(Hook)触发然后在函数内取消是可行的，但函数本身是资源繁重的，指令是完全防止函数被触发。这个想法是内置的钩子(Hook)/函数会触发。

Borrowing from this ticket ，我试图将主函数 setFeaturedImageArtist 放在一个匿名函数中，该函数还将帖子类型打印到 addFilter() 中的控制台。我能够打印帖子类型，但调用 setFeaturedImageArtist 函数没有按预期工作。

wp.hooks.addFilter( 'editor.PostFeaturedImage', 'blocks/featured-image-artist', function() {
    console.log(wp.data.select("core/editor").getCurrentPostType())
    return setFeaturedImageArtist()
});

像这样将 setFeaturedImageArtist 放在包装函数中也不起作用。我假设这是因为它是同一件事。

function checkPostType() {
   console.log(wp.data.select("core/editor").getCurrentPostType())
   return setFeaturedImageArtist()
}

wp.hooks.addFilter( 'editor.PostFeaturedImage', 'blocks/featured-image-artist', checkPostType);

这是过滤器触发的组件:

function setFeaturedImageArtist( OriginalComponent ) {
  return ( props ) => {

    const artistSelect = compose.compose(

        withDispatch( function( dispatch, props ) {
            return {
                setMetaValue: function( metaValue ) {
                    dispatch( 'core/editor' ).editPost(
                        { meta: { 'featured-image-artist': metaValue } }
                    );
                }
            }
        } ),

        withSelect( function( select, props ) {
           let query = {
              per_page    : 20,
              metaKey    : '_author_type',
              metaValue  : 'artist'
            };

            let postType = select("core/editor").getCurrentPostType();
            if ( postType === 'contributor' ) {
                return null
            }

            // Please see below
            // if ( postType === 'contributor' ) {
            //  return {
            //     postType
            //   }
            // }

            return {
                posts: select( 'core' ).getEntityRecords( 'postType', 'contributor', query ),

                metaValue: select( 'core/editor' ).getEditedPostAttribute( 'meta' )[ 'featured-image-artist' ],
            }
        } ) )( function( props ) {
            var options = [];

            // This works in removing the dropdown for authors/artists
            // if (props.postType === 'contributor'){
            //   return null
            // }

            if( props.posts ) {
                options.push( { value: 0, label: __( 'Select an artist', 'blocks' ) } );
                props.posts.forEach((post) => {
                    options.push({value:post.id, label:post.title.rendered});
                });
            } else {
                options.push( { value: 0, label: __( 'Loading artists...', 'blocks' ) } )
            }

            return el( SelectControl,
                {
                    label: __( 'Art Credit:', 'blocks' ),
                    options : options,
                    onChange: ( content ) => {
                        props.setMetaValue( content );
                    },
                    value: props.metaValue,
                }
            );
        }
    );

    return (
      el( 'div', { }, [
        el( OriginalComponent, props ),
        el( artistSelect )
      ] )
    );
  }
}

wp.hooks.addFilter( 'editor.PostFeaturedImage', 'blocks/featured-image-artist', setFeaturedImageArtist  );

这是过滤器触发的编辑组件:

function setFeaturedImageArtist( OriginalComponent ) {
  return ( props ) => {

      const artistSelect = compose.compose(
          ...
      )( function( props ) {
          ... // Cancelling out here works, but resources are loaded by this point.
      });

      return (
          el( 'div', { }, [
              el( OriginalComponent, props ),
              el( artistSelect )
          ])
      );
  }
}

wp.hooks.addFilter( 'editor.PostFeaturedImage', 'blocks/featured-image-artist', setFeaturedImageArtist  );

这是 React error being received :
Element type is invalid: expected a string (for built-in components) or
a class/function (for composite components) but got: undefined.

我不确定最好的方法是什么，并且文档很少/几乎不适用。是否可以创建一个模仿 editor.PostFeaturedImage 但仅触发某些自定义帖子类型的自定义钩子(Hook)？或者有什么方法可以在检查帖子类型的包装器中调用像 setFeaturedImageArtist 这样的函数？

    • 最佳答案

    我尝试重新创建脚本并修复了一些问题:

    const { createElement: el } = wp.element;
const { compose } = wp.compose;
const { withSelect, withDispatch } = wp.data;
const { SelectControl } = wp.components;
const { __ } = wp.i18n;

const ArtistSelect = compose(
    withDispatch(function(dispatch, props) {
        return {
            setMetaValue: function(metaValue) {
                dispatch("core/editor").editPost({
                    meta: { "featured-image-artist": metaValue }
                });
            }
        };
    }),

    withSelect(function(select, props) {
        let query = {
            per_page: 20,
            metaKey: "_author_type",
            metaValue: "artist"
        };

        return {
            postType: select("core/editor").getCurrentPostType(),
            posts: select("core").getEntityRecords("postType", "contributor", query),

            metaValue: select("core/editor").getEditedPostAttribute("meta")[
                "featured-image-artist"
            ]
        };
    })
)(function(props) {
    var options = [];

    // This works in removing the dropdown for authors/artists
    if (props.postType === "contributor") {
        return null;
    }

    if (props.posts) {
        options.push({ value: 0, label: __("Select an artist", "blocks") });
        props.posts.forEach(post => {
            options.push({ value: post.id, label: post.title.rendered });
        });
    } else {
        options.push({ value: 0, label: __("Loading artists...", "blocks") });
    }

    return el(SelectControl, {
        label: __("Art Credit:", "blocks"),
        options: options,
        onChange: content => {
            props.setMetaValue(content);
        },
        value: props.metaValue
    });
});

function setFeaturedImageArtist(OriginalComponent) {
    return props => {
        return el("div", {}, [el(OriginalComponent, props), el(ArtistSelect)]);
    };
}

wp.hooks.addFilter(
    "editor.PostFeaturedImage",
    "blocks/featured-image-artist",
    setFeaturedImageArtist
);
    ArtistSelect 是一个组件，所以我们把它放在 setFeaturedImageArtist 函数之外。 withSelect 对 postType 进行了检查，使其返回 null。取而代之的是，我们传递该变量，然后在组件渲染中返回 null。另一种方法是检查内部 setFeaturedImageArtist 。这是使用 JSX 的固定版本。希望它清楚:
    const { compose } = wp.compose;
const { withSelect, withDispatch, select } = wp.data;
const { SelectControl } = wp.components;
const { __ } = wp.i18n;
const { addFilter } = wp.hooks;

const ArtistSelect = compose(
    withDispatch(dispatch => {
        return {
            setMetaValue: metaValue => {
                dispatch("core/editor").editPost({
                    meta: { "featured-image-artist": metaValue }
                });
            }
        };
    }),
    withSelect(select => {
        const query = {
            per_page: 20,
            metaKey: "_author_type",
            metaValue: "artist"
        };

        return {
            posts: select("core").getEntityRecords("postType", "contributor", query),
            metaValue: select("core/editor").getEditedPostAttribute("meta")[
                "featured-image-artist"
            ]
        };
    })
)(props => {
    const { posts, setMetaValue, metaValue } = props;
    const options = [];

    if (posts) {
        options.push({ value: 0, label: __("Select an artist", "blocks") });

        posts.forEach(post => {
            options.push({ value: post.id, label: post.title.rendered });
        });
    } else {
        options.push({ value: 0, label: __("Loading artists...", "blocks") });
    }

    return (
        <SelectControl
            label={__("Art Credit:", "blocks")}
            options={options}
            onChange={content => setMetaValue(content)}
            value={metaValue}
        />
    );
});

const setFeaturedImageArtist = OriginalComponent => {
    return props => {
        const post_type = select("core/editor").getCurrentPostType();

        if (post_type === "contributor") {
            return <OriginalComponent {...props} />;
        }

        return (
            <div>
                <OriginalComponent {...props} />
                <ArtistSelect />
            </div>
        );
    };
};

wp.hooks.addFilter(
    "editor.PostFeaturedImage",
    "blocks/featured-image-artist",
    setFeaturedImageArtist
);
