如何修复此 PHP 错误尝试访问 wordpress 中 bool 类型值的数组偏移量？

Question

安装插件后，我的 WordPress 主题中出现此错误。我使用的是 Amy Movies 3.5.2 主题，插件是 Amy Movie Extends 3.5.4。我不知道这是否导致了问题。它在第 145 行显示错误

    $permalinks     = get_option('amy_movie_permalinks');
    $cinema_slug    = ($permalinks['cinema_slug']) ? $permalinks['cinema_slug'] : 'cinema'; //This Line

这是我的完整 PHP 代码：

谁能告诉我如何解决这个错误？

Answer 1

显然$permalinks 是假的，所以你需要确保它在该行中是真实的

$movie_slug     = $permalinks && isset($permalinks['movie_slug']) ? $permalinks['movie_slug'] : 'movie';
