Undefined index: mod in function_core.php on line 805 New
Notice: Undefined index: mod in D:\www\source\function\function_core.php on line 805805行：
foreach($_G['setting']['navmns'][$_G['basefilename']] as $navmn) { if($navmn == array_intersect_assoc($navmn, $_GET) || (isset($_GET['gid']) && $navmn['mod'] == 'forumdisplay' && $navmn['fid'] == $_GET['gid'])|| ($navmn['mod'] == 'space' && $_GET['mod'] == 'spacecp' && ($navmn['do'] == $_GET['ac'] || $navmn['do'] == 'album' && $_GET['ac'] == 'upload'))) { $mnid = $navmn; } }deepseek 给的修复：
foreach ($_G['setting']['navmns'][$_G['basefilename']] as $navmn) { // 检查 $navmn 是否为数组且 $navmn 存在 if (!is_array($navmn) || !isset($navmn)) { continue; } $navmn0 = $navmn; // 检查 $navmn0 是否为数组且包含关键字段 if (!is_array($navmn0) || !isset($navmn0['mod'])) { continue; } $mod = $navmn0['mod'] ?? ''; // 使用 null 合并运算符提供默认值 $fid = isset($navmn0['fid']) ? $navmn0['fid'] : null; $do = isset($navmn0['do']) ? $navmn0['do'] : null; // 重构条件判断逻辑，逐层检查索引存在性 if ( $navmn0 == array_intersect_assoc($navmn0, $_GET) || ( isset($_GET['gid']) && $mod == 'forumdisplay' && $fid == $_GET['gid'] ) || ( $mod == 'space' && $_GET['mod'] == 'spacecp' && ( $do == $_GET['ac'] || ( $do == 'album' && isset($_GET['ac']) && $_GET['ac'] == 'upload' ) ) ) ) { $mnid = $navmn; }}
