Working with formulas

[max_power]

Hi all,

 

I've stored a formula in a mysql db table that is pretty basic. To give an example:

 

IF(x=1)
{
  y = 2;
}

IF(x=2)
{
  y = 3;
}

IF(x>2)
{
  y = 0;
}

 

x represents the value from the input field from while y represents the output value (that will be shown through a span element innerHTML).

 

My question is, how can I firstly retrieve this formula from the table and then secondly adapt the x as the value from the input field and then show the result as the output?

 

Thanks

any reason why you dont use it as a function?

Because the formulas will be changed later on by someone else who won't be coding savvy..
