Adding 1 to value called from DB

[liamloveslearning]

Hi all, im trying to call a value from my DB and add the value of 1 to it, so if my db value was 20, id like it to be outputted in the browser as 21.

 

Im having no luck googling  so i thought id ask, is there a name for this function so I know what im looking for? Thanks

Ive tried this with no luck...

 

<?php $d = $row_gethighestworld['intrajobno']; +1 ?>
<?php echo $d; ?>

echo ($field + 1);

In the above, you have the addition operator outside the line termination. That's why it's giving you problems.

Still no luck, its outputting 1 which is to say the addition isnt working :/

 

 <?php 
echo ($row_gethighestworld['intrajobno'] + 1);
?>

Are you just getting the original value, or nothing at all?

[liamloveslearning]

Im jsut getting the value 1, If i echo my variable however I get the value stored in the db

What does this show if you put it instead of the echo?

 

echo '<pre>';

var_dump($row_gethighestworld['intrajobno']);

echo '</pre>';

[liamloveslearning]

It shows 'null', but

<?php echo $row_gethighestworld['intrajobno']; ?> shows my value

Can you post the relevant code, from the db query through the end of the echo statement?
