请检查我的错误日志和. htaccess文件。我的C面板不支持MySql代码；它显示内部服务器500错误。我认为问题出在. htaccess文件中。

这里是. htaccess文件：
RewriteEngine On
RewriteCond %{QUERY_STRING} !(?:^|&)test=yes(?:&|$) [NC]
RewriteRule ^foo/(.*)$ bar/$1?test=yes [NC,QSA,L]
您没有将连接实例传递到您的mysql_query（）函数调用。
insert语句的写入方式不正确，在使用带有保留字或某些特殊字符的查询时，必须像这样指定列值，
"INSERT INTO `mycart` (`customr_id`, `category`, `product`, `price`, `qty`, `output`, `status`) VALUES
('0','0','0','0','1','0','0')"
此外，请确保列名正确。
如果这不能解决您的问题，请从cpanel发布错误消息。
根据错误日志，您需要从中删除目录指令。htaccess文件。
查看这篇文章以供参考。
RewriteEngine On
#RewriteCond %{QUERY_STRING} !(?:^|&)test=yes(?:&|$) [NC]
#RewriteRule ^foo/(.*)$ bar/$1?test=yes [NC,QSA,L]
在中使用此代码。htaccess
