我已经在 php 中编写了一些用于用户注册的代码，但是如果我单击提交按钮，它没有写入数据库。请帮助我。这是我的代码...

您的问题可能是这一行：

$sql = mysql_query("INSERT INTO users VALUES (``,` $username `,` $password `,` $fname `,` $lname `,` $con1 `,` $address `,` $jobtitle `)");

建议始终在 INSERT 语句中声明列名，如下所示：

$sql = mysql_query("INSERT INTO `users` (`col1` , `col1` , `col3`) VALUES ('val1' , 'val2' , 'val3')");
