There are several notices when I run category, with few errors. How to fix the errors? I thought I already define category.

Thanks before.

Use $kategori as set on line two, instead of $_REQUEST['kategori'] .

If any of your others threads helped you solve your problem, mark them as solved.

Do you mean: $kategori = $_REQUEST; ?

It only works once, the first time I enter, the next one similar error appears:
Undefined index: kategori in C:\xampp\htdocs\php_template2\news_manager.php on line 74

Also, where is the solved button? How to mark it when it is solved?

Thanks.

No, I mean replace $_REQUEST['kategori'] with $kategori in your code.

The solved button is near the reply box if I remember correctly.
