Add. php file:
$ Conn = mysql_connect ("localhost", "root", "123 ");
Mysql_select_db ("test", $ conn );
If ($ _ POST ['send'])
{
If (mysql_query ("insert into totest (username, usertitle, usercontent, date) values ('$ _ POST [user]', '$ _ POST [title]', '$ _ POST [content]', now () ", $ conn ))
{
Echo "published successfully ";

My Test







Database totest table:

Userid username usertitle usercontent date
1 2011-11-18
2 2011-11-18
3 2011-11-18
............

Why can't POST values be obtained in the middle?

------ Solution --------------------
$ _ POST [title] is $ _ POST ['usertitle']...
Use the name of your input ......
------ Solution --------------------
Your form is name = "username" name = "usertitle" and your php $ _ POST [user] ',' $ _ POST [title] ', '$ _ POST [content] cannot be obtained.
------ Solution --------------------
This is not a shame! Minor omissions
