问题是你把mysql\uu
和mysqli\u
搞混了。尝试修复下面的问题
mysqli_connect("localhost","user","password");
mysqli_select_db("towerroa_TRA", $con);
mysqli_query($con, "DELETE FROM `itsnb_phocaguestbook_items` WHERE `content` LIKE '%<a%'")or die ("Couldn't execute query: ".mysqli_error());
mysqli_connect(“本地主机”、“用户”、“密码”);
mysqli_select_db(“towerroa_TRA”$con);
mysqli_query($con,“从`itsnb_phocaguestbook_items`中删除`content`如'%问题是您将mysql\u和mysqli\u
混为一谈。请尝试修复以下问题
mysqli_connect("localhost","user","password");
mysqli_select_db("towerroa_TRA", $con);
mysqli_query($con, "DELETE FROM `itsnb_phocaguestbook_items` WHERE `content` LIKE '%<a%'")or die ("Couldn't execute query: ".mysqli_error());
mysqli_connect(“本地主机”、“用户”、“密码”);
mysqli_select_db(“towerroa_TRA”$con);
mysqli_query($con),从'itsnb_phocaguestbook_items'中删除'content',如“%用mysqli.*
替换所有mysqli.*
函数
mysqli_select_db("towerroa_TRA", $con);
应该是
mysqli_select_db($con,"towerroa_TRA");
应该是
mysqli_select_db($con,"towerroa_TRA");

那么您不能执行查询的错误是什么呢?另外,您到处都在使用不推荐使用的mysql\uu
函数,除了mysqli\u查询
部分。将所有内容都更改为mysql\u*
查询或mysqli\u*
查询。强烈建议使用mysqli\u
函数!有趣的是没有错误,只要t它无法执行查询。请尝试使用$con=mysql\u connect(“localhost”、“user”、“password”)代替$con=mysql\u connect(“localhost”、“user”、“password”)或die(mysql\u error())-这会给您带来任何错误吗?您的代码中的mysqli_查询是要成为mysql_查询吗?您不能执行查询中的错误是什么?此外,您到处都在使用不推荐使用的mysql_
函数,除了mysqli_查询
部分。将所有内容更改为mysql_*
查询或mysqli
查询。强烈建议使用mysqli\u
。有趣的是,没有错误,只是它无法执行查询。请使用$con=mysql\u connect(“localhost”、“user”、“password”);而不是$con=mysql\u connect(“localhost”、“user”、“password”)或die(mysql\u error())-这是否会给您带来任何错误?您的代码中的mysqli_查询是否打算成为mysql_查询?Iv尝试了这一点,但仍然得到“无法执行查询:”错误消息:-(您是否已三次检查了所有数据库名称、表名和用户/密码等?以及:
