Change value of Option

[Capt-Zeanie]

Is there a way to change the value of the option

Example:
I am using SCEditor to create my BBCode. In the editor it has font size which is create a bbcode tag of
[size=4]this is font size 4 ie 18px [/size]

Now I want JBBCode to read the 4 and then validate it, and then return the correct font size value in the validation function which is then placed in the html render.
eg.

style="font-size:18px">this is font size 4 ie 18px

However I keep getting

style="font-size:4px">this is font size 4 ie 18px

How do I change the option value for a new value.

I am using JBBCode to read this size using...
$builder = new CodeDefinitionBuilder('size', '

{param}

');
$builder->setUseOption(true)->setOptionValidator(new \JBBCode\validators\FontValidator());
array_push($this->definitions, $builder->build());

My fontValidator is...
public function validate($input)
{
if (is_numeric($input) && $input <= 7 && $input >= 1) {
switch ($input) {
case 1:
return 10;
break;
case 2:
return 13;
break;
case 3:
return 16;
break;
case 4:
return 18;
break;
case 5:
return 24;
break;
case 6:
return 32;
break;
case 7:
return 48;
break;
}
} else {
return 16;
}
}

Thank you so much if you help me

Please paste the code from your FontValidator and how you are using it. Also please use the Markdown Code Syntax: https://guides.github.com/features/mastering-markdown/

@Capt-Zeanie Actually the method InputValidator::validate() is not supposed to return a value which replaces the current value, so all of your attempts result in converting the value to boolean TRUE.

See interface InputValidator
