Passing query sum result to php variable

[GFOnyX]

I have the following query that gives me the result i want. In a nutshell it searches two columns to find the max value in each of these two columns and returns the sum of these two values.

 

When i try to pass it to a variable in php it doesn't seem to work. I want to be able to pass the sum in a variable so i can use the variable later into an IF Condition.

For example:   if ($scoremax >= '160') { code here }

 

Here is my query:

select (max(scoreioa) + max(scoreioa2)) from result where username='username'

and here is the php code:

$maxscore = mysql_query("select (max(scoreioa) + max(scoreioa2)) from result where username='username'");
mysql_data_seek($maxscore, $scoremax);
$row = mysql_fetch_row($maxscore);
$scoremax = $row[0];

remove that mysql_data_seek line.

remove that mysql_data_seek line. 

I did but it still doesnt seem to work. Its like the sum is not being stored in the $scoremax variable.

dumb question.. are you sure you are properly connected to the db and all that? 

 

do this:

$maxscore = mysql_query("select (max(scoreioa) + max(scoreioa2)) from result where username='username'") or die(mysql_error());
$row = mysql_fetch_row($maxscore);
echo "<pre>";print_r($row); echo "</pre>";
$scoremax = $row[0];
echo $scoremax;

do you get any errors displayed? what does the print_r show? what is echo'd out? is 'username' really the username?

Yes i am propelry connected to the DB since i can already pass scores to the DB and read data from it.

 

Sorry about the username,it was a mistake from my end.It was supposed to be $username.

 

The result however is still that is not working.

 

By applying the code you wrote i get this:

Array(    [0] => )

[.josh]

okay, are you sure $username has the expected value?  If you run the query directly in mysql (via phpmyadmin or commandline) do you get expected results?

.josh it seems to be working.Thank you very much.

 

I had the code written in wrong position inside the php file. It has many lines of code already in it and i got a little lost. I tried an IF condition using the $scoremax variable and i got the results i wanted.

 

Thanks again!

 

BTW This site is amazing!
