Re: String passed to object constructor turning into an instance of that object?

     }

will parse and execute, but: - the page will contain "missing value!" for each <option> in the <select> this is generating - it will *not* contain "missing name!" - the <option> tags in the final output don't have content or value (they should have both). If I uncomment that else, I get: adding option <name1> with <value1>

     name <value1>

Catchable fatal error: Object of class SelectBoxOption could not be converted to string in <webroot>/includes/classes/core/display/form/input/SelectBoxOption.php on line 12

What's the actual line #12 in the file SelectBoxOption.php? The SelectBoxOption code you presented has 11 lines unless it's a CNP error.

Whups, thought I noted that. I trimmed a couple of blank lines; line 12 in the file is that print in the else. I found trying to print $name triggers the same error anywhere in that function, too; as I noted further down it seems the string that's passed in is getting mutated into an object. (Whose missing toString function is what led me here - but it works fine in PHP 4.3...) -kgd
