Question

In the script below, I’m trying to dynamically set the css width attribute on the .sidebar and .content elements by subtracting the value stored in the ‘my_sidebar_width’ variable from 950

I’m getting an error:

Parse error: syntax error, unexpected
T_DNUMBER

if(get_option('my_sidebar_width') !=='')
    $my_stringData .= 
    ".sidebar{width:".get_option('my_sidebar_width')."}
    .content{width:".950-get_option('my_sidebar_width')."}";

This is my first foray into calculating values in PHP. Do I need to explicitly convert the ‘my_sidebar_width’ variable to an integer? Perhaps more?

Answer 1

Try to put the substraction in parantheses, like this:

( 950-get_option("cb2_sidebar_width") )
