}
	
?>

<?=$pagination?>

the ERROR is :

Notice: Use of undefined constant num - assumed 'num'

$total_pages = $total_pages[num];

i dont know what is that mean??

 

[Bruce_KD]

It isn't an error, just a "Notice"

It's really $total_pages['num'] (Note, "num" is a String)
In php, you can definite constants
Variables are prefixed with the $, but constants have no prefix.
Fortunately, php is smart enough to realize that in $total_pages[num], since you have no constant named num, you must mean the string 'num'.

When you do not use quotes:

$var[num]

it is assumed to be an array.

Bruce, you are correct :bingo: Use $total_pages['num'] instead of $total_pages[num]
