register_uninstall_hook不工作在wordpress插件卸載

Question

嗨，我做了一個插件，現在我想當用戶停用插件，所有的功能和帖子和選項值和元值也被刪除。

我寫了鉤，使文件在那裏我刪除所有的值，但它沒有工作，我用這個鉤子

register_uninstall_hook('foo_uninstall.php', $callback); 

是否有任何其他鉤用於此目的。

這裏是我的foo_uninstall.php代碼

<?php 
global $wpdb; 
$del_prefix = $wpdb->prefix; 

//if uninstall not called from WordPress exit 
if(!defined('WP_UNINSTALL_PLUGIN')) 
    exit(); 

//=========> Delete foo Options 
    delete_option('foo_theme_directory'); 
    delete_option('foo_plugin_slug');

    delete_option('foo_breadcrumbs_setting'); 
    delete_option('foo_sidebar_setting'); 
    delete_option('foo_comments_setting'); 
    delete_option('foo_bgcolor'); 
    delete_option('widget_foo_article_widget'); 
    delete_option('foo_cat_children'); 

//=========> Get and Delete Foo Page 
    $foo_get_page = $wpdb->get_results("SELECT * FROM ".$del_prefix."posts WHERE post_type='page' And 

post_content = '[foo_article]' And post_name = 'article'",ARRAY_A); 

    $fooPageID = $foo_get_page['ID']; 

    $wpdb->query("DELETE FROM ".$del_prefix."postmeta WHERE post_id = '$fooPageID'"); 

    $wpdb->query("DELETE FROM ".$del_prefix."posts WHERE post_title Like '%article%' And post_type =

//=========> Delete foo Terms and Taxonomies 
    $foo_Find_tax = $wpdb->get_results("SELECT term_taxonomy_id FROM ".$del_prefix."term_taxonomy WHERE

    $fooTaxID = $foo_Find_tax[0]['term_taxonomy_id']; 

    foreach($foo_Find_tax as $foo_find_tax){ 
    $fooTaxID = $foo_find_tax['term_taxonomy_id']; 

    $delete_foo_relations = $wpdb->query("DELETE FROM ".$del_prefix."term_relationships WHERE 

term_taxonomy_id='$fooTaxID'"); 
    $delete_foo_tax = $wpdb->query("DELETE FROM ".$del_prefix."term_taxonomy WHERE 

term_taxonomy_id='$fooTaxID'"); 
    $delete_foo_terms = $wpdb->query("DELETE FROM ".$del_prefix."terms WHERE term_id='$fooTaxID'"); 
    } 

//=========> Delete terms_order From wp_terms

//=========> Delete comments of articles 
    $foo_comments = $wpdb->get_results("SELECT ID FROM ".$del_prefix."posts WHERE post_type =

    $foo_comment_id = $foo_comments->ID; 

    foreach($foo_comments as $foo_comment){ 
     $foo_comment_id = $foo_comment->ID; 
     $wpdb->query("DELETE FROM ".$del_prefix."comments WHERE comment_post_ID='$foo_comment_id'"); 
    } 

//=========> Delete All Articles and Attachments 
    $foo_all_articles = new WP_Query('post_type=foo_article&posts_per_page=-1'); 

    if($foo_all_articles){ 
     while($foo_all_articles->have_posts()) : 
      $foo_all_articles->the_post(); 
      $fooID = get_the_id(); 

      $foo_del_args = array('post_parent' => $fooID); 
      $foo_attachments = get_children($foo_del_args); 

      if($foo_attachments){ 
       foreach($foo_attachments as $foo_attachment){ 
        wp_delete_attachment($foo_attachment->ID, true); 
       } 
      } 
      wp_delete_post($fooID, true); 
     endwhile; 
    } 

//=========> Remove all files and images 
    unlink(get_template_directory()."/foo_articles.php");

    unlink(get_template_directory()."/taxonomy-foo_cat.php"); 
    unlink(get_template_directory()."/foo_search.php"); 

?>

嘗試register deactivation hook，而不是寄存器卸載鉤子。請多做refer here。

register_uninstall_hook( __FILE__, 'foo_on_uninstall'); 

function foo_on_uninstall() { 
    // write your uninstall code 
}
