Problem with using bracket operator in player statistic

Hi Luko,

From the error it looks like there might be mismatched parentheses, which means that there are not an equal number of “(” and “)”. I’d be happy to assist you further if you could paste in the output of SportsPress > Settings > System Status below, using the “code” button.

Sorry for bumping the topic but I’ll try to explain further what I need.
I have this variables in player performance:
1. unjevig
2. unjevid
3. nastupdoma
4. nastupgost
I want to calculate something like this:
=unjevig + ( unjevid / nastupdoma ) / nastupgost + 1
Only thing that worked with brackets was this formula:
=( unjevig + unjevid) / ( nastupgost + 1 )

Does the nested brackets work?
Everything else is throwing mismatched parentheses error. I updated plugin to version 1.6

Ok. I figured it out …
It looks to me that equation builder isn’t supporting nested brackets. Without that there is no way (as far as I know) to solve this formula. To bad..
??

@lukodp You’re right, the equation is throwing an error even though it should be working. The reason this is happening is because of a zero-denominator check in sp-core-functions.php: line 1091

if ( $eos->solveIF( substr( $equation, $pos + 1 ), $vars ) == 0 )
				return 0;

The check is attempting to solve the equation after the first “÷”, throwing a mismatched parantheses error because the equation being checked is something like:

nastupdoma ) ) / ( nastupgost + 1 )

I’ll need to fix this part of the check so that it looks for a denominator with matching parentheses instead i.e.

0 !== ( nastupgost + 1 )

For now, a temporary solution (if you’re sure that the denominator will not be zero) is to comment out the lines in sp-core-functions.php between 1089-1093.

I’ll add this issue to our GitHub project for fixing in the next update.

A more permanent solution added to core: https://github.com/ThemeBoy/SportsPress/commit/813eb3fe9001195f6f2ebb650c5bf6a261654ca9

This checks each sub-equation by splitting the equations wherever a division occurs, then looks at that equation if the parentheses match and return zero if that sub-equation is zero.

This version of the zero-denominator check also works properly with your equation ??

Hy,

I actually give up from that project because of this issue.
Now I’m starting it again here: https://regijasjever.com.hr/
Can’t describe how thankful I am ??

Best regards,

Luko
