	</table>
	</form>

Each form field is filled with errors:

<br /><b>Notice</b>: Undefined variable: event in <b>C:\xampp\htdocs\php_template2\event_manager.php</b> on line <b>173</b><br />

<br /><b>Notice</b>: Undefined variable: tempat in <b>C:\xampp\htdocs\php_template2\event_manager.php</b> on line <b>179</b><br />

Line 173: <input type="text" name="event" value="<?php echo $event; ?>"/>

Line 179: <input type="text" name="tempat" value="<?php echo $tempat; ?>"/></td>

Those are just two of them, there are three more that are alike.

Also why each form field are filled with unnecessary errors, these errors appears before I fill in the form field with data.

Already answered in one of your other threads. The variables did not get a value yet.

I just define the variables. Now this is the new error:

Unknown column 'keterangan' in 'field list'

Sounds like a missing column in your table, or a typo.
