Hi, All:
I have some information stored in the database.
When I try to show them, sometimes it give me the
following warning:
Warning: printf(): Too few arguments ...
Here is the problematic code:
printf("<textarea COLS=56 ROWS=7 name=\"description\">$des</textarea> <br>");
I figured out that if there are "%" in the
string $des, it will give me this warning. But
I want to show "%" in the textarea. How can
I do that? Further, how to do the input filtering?
Are there any modules that I can use?
Thanks in advance for any help.
