Any help rep+

 

Execute this code and write here what error it shows:

$sql="INSERT INTO forum_categorys(catname, desc, ffname)
VALUES
('$categorys', '$descc', '$categorys')"; 
$result=mysql_query($sql) or die(mysql_error);

PHP:

 

it prints

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'desc, ffname) VALUES ('yes', 'yes', 'yes')' at line 1

Code (markup):

BTW its mysql_error()

 

Can you write here "forum_categorys" table structure? And write here what the variable $sql prints ( echo($sql); ).

 

Or try this:

$sql="INSERT INTO forum_categorys (`catname`, `desc`, `ffname`)
VALUES
('$categorys', '$descc', '$categorys')";
$result=mysql_query($sql) or die(mysql_error);

PHP:

 

your table structure is not correct that's why that is giving error
