New forms and writing mysql sql statement

1. Create a new form when the canceled check mark id

 

 2.

To user table (user and pass columns) insert data,

$sqI="INSERT INTO user(user,pass) values($user,$pass)";

When we as an int time, sq | executed in the database

insert into user(user,pass) values(001,001);

However, when performing a char type data, SQL statement becomes:

insert into user(user,pass) values(abc,abc);

Now we can see the problem now, because char type to add "symbol.

We will change the SQL statement:

$sq|= "INSERT INTO user(user,pass) values(" .$user.",'" .$pass.")"; 即可。
