Operand error...

[Karl-Arne Gjersøyen]

$oppdater_lager_med_antall_kg = $kg_pa_lager +
$kg_fra_transportdokument_inn_pa_valgt_lager;


result:
*Fatal error*: Unsupported operand types in *
/Users/karl/Sites/kasen/io/kp/index.php* on line *2970

*I have also tried this:
$kg_pa_lager += $kg_fra_transportdokument_inn_pa_valgt_lager;

Both of them return this Fatal error.
I am using Dreamweaver CS6 and the syntax check in my software say: "No
syntax error"

What am I doing wrong this time?

Thanks for your good advice!

You do a var_dump on each variable to see what type they were defined as.

NULL array(2) { [0]=> string(3) "100" [1]=> string(3) "340" }

That is one var. What is the other var?

Thank you very much!
Now I know the error.. One of those variables are NULL! When I fix it I
think it work!

actually, the null is ok I think. The array is wrong - you can't 'add'
an array to a scalar variable, which an integer or null is.

Yes, it is me and arrays again :D

$resultat = mysql_query($sql, $tilkobling) or die(mysql_error());
$antall = mysql_num_rows($resultat);
for($i = 0; $i < $antall; $i++){
$rad = mysql_fetch_array($resultat, MYSQL_ASSOC);

and write it tis way can perhaps make someting more correct?
For example $variable[$i] ?

Not sure what your question is now. But - $rad will contain a single
row of values here, all in an array such as
$rad['field_name1'],$rad['field_name2'],$rad['field_name3'],.... .
