Php 无法重命名自定义post类型的slug

我一辈子都不能改变我的自定义帖子类型。我尝试过刷新重写并重新保存永久链接。但它仍然显示了老鼻涕虫

My functions.php

register_post_type( 'roofers-peakdistrict',
    array(
        'labels' => array(
            'name' => __( 'Peak District' ),
            'singular_name' => __( 'Roofers Peak District' ),
            'add_new' => 'Add New Peak District Page',
            'add_new_item' => 'Add New Peak District Page',
            'edit' => 'Edit Peak District Page',
            'edit_item' => 'Edit Peak District Page',
            'new_item' => 'New Peak District Page',
            'view' => 'View Peak District Page',
            'view_item' => 'View Peak District Page',
            'search_items' => 'Search Peak District Pages',
            'not_found' => 'No Peak District Pages found',
            'has_archive' => true,
            'slug' => 'roofers-peak-district'
            'hierarchical' => true,
            'not_found_in_trash' => 'No Peak District Pages found in Trash',
            'parent' => 'Parent Peak District Page', ),
            'public' => true,
            'supports' => array(
                'title',
                'editor',
                'thumbnail'
                ),
            'taxonomies' => array('category'),
            )
        );

我的帖子出来的时候就像

---

我需要将其更改为

您使用了错误的数组 用这个代替

register_post_type( 'roofers-peakdistrict',
    array(
        'labels' => array(
            'name' => __( 'Peak District' ),
            'singular_name' => __( 'Roofers Peak District' ),
            'add_new' => 'Add New Peak District Page',
            'add_new_item' => 'Add New Peak District Page',
            'edit' => 'Edit Peak District Page',
            'edit_item' => 'Edit Peak District Page',
            'new_item' => 'New Peak District Page',
            'view' => 'View Peak District Page',
            'view_item' => 'View Peak District Page',
            'search_items' => 'Search Peak District Pages',
            'not_found' => 'No Peak District Pages found', 
           ),
            'has_archive' => true,
            'rewrite' => array(
                  'slug'=>'roofers-peak-district'

                 'title',
                 'editor',
                 'thumbnail'
           ),
           'taxonomies' => array('category'),
    )

))
