Php PDO无法将数据插入数据库
我是pdo的新手。在这里,我尝试使用下面的代码将数据插入数据库。但是,我无法将数据插入数据库。我得到以下错误 致命错误:对非对象调用成员函数prepare 我在SO和互联网上搜索了这个错误。有人说加上全球$conn;在代码的顶部。我添加了这些代码,但得到了相同的错误。有人告诉我如果我想清除这个错误该怎么做吗 Config.phpPhp PDO无法将数据插入数据库,php,pdo,Php,Pdo,我是pdo的新手。在这里,我尝试使用下面的代码将数据插入数据库。但是,我无法将数据插入数据库。我得到以下错误 致命错误:对非对象调用成员函数prepare 我在SO和互联网上搜索了这个错误。有人说加上全球$conn;在代码的顶部。我添加了这些代码,但得到了相同的错误。有人告诉我如果我想清除这个错误该怎么做吗 Config.php 您没有打印您的异常。如果你有任何例外,你将得不到它。我认为$conn=null中的问题; $conn=null;这一行使您的连接对象无效,执行这一行后,您的pdo对象无
您没有打印您的异常。如果你有任何例外,你将得不到它。我认为$conn=null中的问题; $conn=null;这一行使您的连接对象无效,执行这一行后,您的pdo对象无效。为此,您在循环中得到了此错误。它应该在执行此行之前执行所有其他查询。只要拆下这条线。并按如下方式打印您的异常消息: 试试这个:
您的$conn声明在哪里?数据是复数且不可数@撤销:复数意思?无法理解config.php中的内容?意味着您不能使用数据:-Dsame错误-致命错误:在非对象上调用成员函数prepare在哪一行?你能给我这行吗?是的,我替换了我的config.php代码。但在59号线上也有同样的错误。第59行是->$stmt=$conn->prepareINSERT到电子发票关税TariffSlNo、TariffDate、TariffDetails、NoOfNights、TariffRate、TariffPrice、TariffTax、TariffNetTotal、TariffAddTotal、TariffFinalTotal、VoucherID_Fk、CreatedOn值:c_slno、:c_date、:c_NoOfNights、:c_rate、:c_price、:c_tax、:c_nettotal、,:c_totalamount,:c_finaltotal,:凭证,现在@user3181207:是否删除了此行$conn=null?你把我的代码粘贴到你的database.php了吗?我又更新了我的问题。我按照您在上述评论中所说的更改了代码。现在,我面临一个奇怪的问题。我可以将数据插入数据库。您可以在编码ebmealplans、ebroomtypes、ebvouchers和EBVOUCHER中看到四个数据库表。EBD凭证表无法将数据插入数据库,其余表是否完全插入数据?我也没有犯任何错误。我很困惑。您可以在下面的代码中看到
