vBulletin Custom Plugin Options - Changing Carriage Returns!

Is it all working except that InfernoShoutbox.userframe doesn't show the right value, or does it not work at all because the "var RULES = " line isn't valid js?

Forgive me, I might've been unclear, haha

Basically, here's what I've got (my whole .js code):
http://paste2.org/p/2073301#line-549
As you can see, I'm already modifying the variable RULES on line 549 to change all \n tags to be <br />.

Now, the RULES var is called from an option in a setting on my Forum. In this setting, as you can probably guess, you can input a description of your rules that will display.

I have the following defined in a template:

var RULES = "$vboptions[ishout_rules]";

Before I go on, someone on another forum told me:

A JavaScript error is probably occurring. Based on the limited information that I have, I would guess that this is due to the way you're loading the rules value into JavaScript. You probably have a variable definition that looks like:

var RULES = 'a
b';

...leading me to understand that I'm bringing in invalid js.

So, the contents of the ishout_rules option that are like:

...would in fact not be valid js and cause an error.


So, if I were to design a Plugin, what hook location should I use and what should it contain? Also, how would I get a custom variable to be accessible by a template?
Or, is there a way to fix the js error?


Thanks,

OK, I think this should work: create a plugin using hook parse_templates and code like this:

$ishout_rules = addcslashes($vbulletin->options['ishout_rules'], "\r\n'\\");

Then in your template:

var RULES = "$ishout_rules";

This won't change the newlines to <br>, but if you are allowing html in your rules then the person writing the rules should put <br> where they want a newlines.

By the way, you asked about how to access a variable in the other thread and I'm sorry it didn't occur to me that you might have problems like this with a string.

Figured it out, thanks for your help!
I had to put some PHP code into the cache_templates page then modify the output in my .js file
