Php PDO INSERT PREADED语句，无错误，但未插入数据
我正试图将我的代码重构为PDO就绪，但出现了一些错误，无法理解原因：以下使用PDO准备好的插入查询的代码运行正常，我无法获得任何错误消息（除了“未定义索引”上的一些警告），但没有在人口统计表中插入任何数据。我还检查了MySQL，并且我拥有写入或删除所有内容的正确权限。任何帮助都将不胜感激。我有一个print\r（$\u POST）运行正常，但无法从stmt->execute（）命令中获取任何值（我尝试了print\r（$value=stmt->execute（））；没有错误但没有消息。以下是代码：Php PDO INSERT PREADED语句，无错误，但未插入数据,php,mysql,sql,pdo,Php,Mysql,Sql,Pdo,我正试图将我的代码重构为PDO就绪，但出现了一些错误，无法理解原因：以下使用PDO准备好的插入查询的代码运行正常，我无法获得任何错误消息（除了“未定义索引”上的一些警告），但没有在人口统计表中插入任何数据。我还检查了MySQL，并且我拥有写入或删除所有内容的正确权限。任何帮助都将不胜感激。我有一个print\r（$\u POST）运行正常，但无法从stmt->execute（）命令中获取任何值（我尝试了print\r（$value=stmt->execute（））；没有错误但没有消息。以下是代码
