The point submission has been unable to write to the database, if (Isset ($_post[' submit '))) is not executed at all? For advice

------Solution--------------------
It's no problem to test your code, unless you have a page that's not dealadduser.php

PHP code

!--? phpif (isset ($_post[' submit '])) {Mysql_con  Nect ("localhost", "root", "");  mysql_select_db ("soft");  mysql_query ("Set character set GBK");  $username =$_post["username"];  $password =$_post["Password"];  $sql = "INSERT INTO ' users ' (' name ', ' Pass ') VALUES (' $username ', ' $password ')";  Echo $sql;     mysql_query ($sql);     Mysql_close (); }?--> 
------solution--------------------
 isn't your page dealadduser.php? 
 if not, the dealadduser.php page should be 
   
   

    
     PHP code 
    
    
!--? phpif (isset  ($_post[' submit '))  {mysql_connect ("localhost", "root", "");  mysql_select_db ("soft");  mysql_query ("Set character set GBK");  $username =$_post["username"];  $password =$_post["Password"];  $sql = "INSERT INTO ' users ' (' name ', ' Pass ') VALUES (' $username ', ' $password ')";  Echo $sql;     mysql_query ($sql);     Mysql_close (); }?-->
