vBulletin Custom Plugin Options - Changing Carriage Returns!

[Mko]

Hey again all,
I've been developing a plugin, and in the vBulletin Options for this plugin, there's a textarea where users can input a paragraph for their rules.

I have this following contents in my database, which is being called:

a
b

^That is EXACTLY as it is in the database, which causes my plugin not to work.
An image (just to be more clear):


Now, in the database, there is no \r or \n or anything of the sort. It is exactly as I mentioned above.

I'm working primarily with JavaScript (innerHTML), and need to find a way to make carriage returns be interpreted as <br /> tags and NOT as physical carriage returns.

Thanks in advance for any help,
Mark

P.S. If someone needs the .js file, let me know

you'd want to use \n for new line or (and it might be deprocated) \r for return, however \n works for me

I might've not been clear. My apologies.

You might try you using str replace and replace \n (i know what you said but give it a try! or \r), like this:

PHP Code:

var text = "this
is 
some
text "; 
var new_text = text.replace("<br />", "\n"); 
document.write(new_text);

The picture of your database shows that each character is in a seperate row?

Didn't work, sadly. Thanks though!

&no, it's just a cell in the db program I'm using.

in that case do you can split string like this in js

PHP Code:

text=text.split(' ').join('<br />')

Still no success.

I had an idea though. Regarding vB Templates, when they're saved, they don't print each carriage return. So, does anyone know how they do it?

Try this:

PHP Code:

$jsstring = addcslashes(nl2br(htmlspecialchars($option)), "'\\"); 


Where $option is the string from the database, and $string is what you'll use in your template for the js variable, in single quotes, like:

var jsvar = '$jsstring';

This assumes that what's being entered and saved in the db is not html. If it is, you don't want the htmlspecialchars() in there (and then they really should be entering the <br> tags themselves, but that's OK).

Edit: Another thought - you could allow bbcode markup, and then when you pass it through the bbcode compiler it will change \n to <br>.

The templates are html, so you'd have to explicitly use <br> where you wanted them in the output.

So close, but yet it doesn't work. :/
Basically, if I've still been unclear, I'm calling the variable (which I declare in a template):

<script type="text/javascript">
<!--
var RULES = "$vboptions[ishout_rules]";
// -->
</script>

Into my .js file:

InfernoShoutbox.userframe.innerHTML = RULES;

So, my problem is basically how do I manipulate the input in the ACP in JavaScript and not in PHP?

[kh99]

Hmm...well I was thinking you might be able to fix the problem on the php side by changing what value you're giving the RULES var, and that would require another plugin instead of just using $vboptions[ishout_rules] directly in a template. But maybe I don't understand what the issue is. 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?
