Notice: Use of undefined constant id assumed 'id' in index.php on line

the main reason you are seeing these warnings is because you have a mysql query and there are some variables that are not being used. i know i get it because when i do mysql queries i use the wild card. for example i used this:

$sql = 'SELECT * FROM forums ORDER BY id DESC'

by doing the above query, im selecting all the fields but im not using them all of the arrays variables so thats why i get this display error. so you can do two things. instead of doing a query with wild card, just select the fields you are going to need. for example, i only need the id,name,title of the forums table. so this is how my query would look like:

$sql = 'SELECT id,name,title FROM forums ORDER BY id DESC'

see the difference.. its all about good coding. it also helps your server reduce cpu resources if you stop using the wild card on your queries. or if you dont want to edit your code, you can do this other option to get rid of this error:

edit your php.ini file

go to the shell, login as root and enter these commands:

open php.ini

look for this line:

replace it with this:

saved your changes: Hit Control-x

at the prompt: Do you want to save changes... say YES

now reboot your apache server:

DONE - now you shouldn't be getting these errors. if you still get them, then you did something wrong. make sure you followed these steps carefuly. if you still have problems reply and i will investigate more for you. make sure to enter the errror you are getting.
