一直在与一个bug斗争。在已创建的{taxonomy}钩子上，在已编辑的{taxonomy}钩子可以正常工作并上载所需的文件，没有问题。根据以下代码，我添加了自定义字段类型和自定义分类类型。工作正常。

add_action( \'init\', \'addingCustomType\' ); 


function addingCustomType() { 
    register_post_type( \'work\', 
        array( 
            \'labels\' => array( 
                \'name\' => \'Works\', 
                \'singular_name\' => \'work\', 
                \'add_new\' => \'Add New\', 
                \'add_new_item\' => \'Add New Work\', 
                \'edit\' => \'Edit\', 
                \'edit_item\' => \'Edit Work\', 
                \'new_item\' => \'New Work\', 
                \'view\' => \'View\', 
                \'view_item\' => \'View Work\', 
                \'search_items\' => \'Search Works\', 
                \'not_found\' => \'No Works found\', 
                \'not_found_in_trash\' =>  
                    \'No Works found in Trash\', 
                \'parent\' => \'Parent Work\'                     
            ), 
            \'public\' => true, 
            \'show_in_rest\' => true,
            \'rest_base\'    => \'works\',
            \'menu_position\' => 20, 
            \'supports\' => array( \'title\', \'editor\', \'thumbnail\' ), 
            \'taxonomies\' => array( \'work_type\' ), 
            \'menu_icon\' =>  
                plugins_url( \'works.png\', __FILE__ ), 
            \'has_archive\' => true,
            \'exclude_from_search\' => true 
        ) 
    );

    register_taxonomy( 
        \'work_type\',       
        \'work\',                  
        array( 
            \'labels\' => array( 
                \'name\' => \'Work Type\', 
                \'add_new_item\' => \'Add New Work Type\', 
                \'new_item_name\' => \'New Work Type Name\'
            ), 
            \'show_ui\' => true, 
            \'show_tagcloud\' => false, 
            // \'hierarchical\' => true,
            \'public\' => true, 
            // \'show_in_rest\' => true,
            // \'rest_base\'    => \'work_type\',
        )
    ); 
}

根据下面的代码，在编辑和添加（new）到我的自定义分类法（work\\u type）上都添加enctype，效果很好，在这两种形式中都可见。

add_action(\'work_type_term_edit_form_tag\', \'update_edit_form\' );
add_action(\'work_type_term_new_form_tag\', \'update_edit_form\' );

function update_edit_form() {
    echo \' enctype="multipart/form-data"\';
}

根据以下代码，将上传文件输入字段添加到两个场景的管理面板添加（&A）；编辑哪个效果很好。

add_action( \'work_type_edit_form_fields\', \'ch4_br_book_type_new_fields\', 10, 2 );
add_action( \'work_type_add_form_fields\', \'ch4_br_book_type_new_fields\', 10, 2 );


function ch4_br_book_type_new_fields( $tag ) {
    $mode = is_object( $tag ) ? \'edit\' : \'new\';
   

    switch($mode) {
        case \'edit\': 
            // icon
            echo \'<div class="form-field">\';
            echo \'<label for="tag-category-url">Choose an icon</label>\';
            echo \'<input type="file" id="typeIcon" name="typeIcon">\';
            echo \'</div>\';  
      

        break;
        case \'new\':
            // icon
            echo \'<div class="form-field">\';
            echo \'<label for="tag-category-url">Choose an icon</label>\';
            echo \'<input type="file" id="typeIcon" name="typeIcon">\';
            echo \'</div>\';  
        break;
    }
}

根据下面的代码，我试图使用wp upload函数来上传文件，这在编辑的{taxonomy}hook中非常有效。但是，它在created/create{taxonomy}hook&；中不起作用$_文件为空，文件[\'error\']=“quot；指定的文件未能通过上载测试"E；

add_action( \'edited_work_type\', \'ch4_br_save_book_type_new_fields\', 10, 2 );
add_action( \'created_work_type\', \'ch4_br_save_book_type_new_fields\', 10, 2 );
function ch4_br_save_book_type_new_fields( $term_id, $tt_id ) {
   

    if ( !$term_id ) {
        return;
    }

  
    if ( ! function_exists( \'wp_handle_upload\' ) ) {
        require_once( ABSPATH . \'wp-admin/includes/file.php\' );
    }

    $uploadedfile = $_FILES["typeIcon"];
    $upload_overrides = array( \'test_form\' => false );
    $iconFile  = wp_handle_upload( $uploadedfile, $upload_overrides );
    if ($iconFile[\'error\']) { 
        print_r($iconFile[\'error\']);
        // print_r("file", $_FILES);
    }

    $returnvalue =  update_term_meta( $term_id, \'work_type_icon\', $iconFile );
  
}

有人知道这种行为是从哪里来的吗？是否有更好的钩子来触发分类法创建，正如我所认为的那样创建（&P）；是否创建挂钩重置$\\u文件？
