Is this the correct way to add to a variable?

[HughbertD]

I want to add 10 to the value startrow in my URL

 

echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow+10).'">Next</a>';

 

Is that correct?

 

It seems like it is simply assigning startrow to be 10 rather than adding anything

Yes, that seems right. Try to echo your $startrow and see what you get.

Make sure you are grabbing the existing value for the URL variable startrow, ge:

$startrow = $_GET['startrow'];

 

Otherwise the startrow variable wont increment.

// grab current startrow value
$startrow = $_GET['startrow'];

// display link and increment startrow by 10
echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow+10).'">Next</a>';
