Fixed a minor Bug when viewing the BBCode Help

Hi @RedEnzian. 

Thank you very much for the plugin!

I think there is a small bug.

When parsing the following code, I obtained an image with a lot of "/div" characters, while with the same code, parsing directly on http://quicklatex.com/ does not have that problem. Could you please check?

Image on my forum:

 

 

Image obtained when parsing directly on http://quicklatex.com/:

Figured it out.

In quickLatex.php find 

$find = array("&#092;", "&amp;", "<br />", "&lt;", "&gt;", 
                      "&quot;", "&#39;", "&#33;", '<p>', '</p>');
        $replace = array("\\", "&", "", "<", ">", '"', "'", "!", "", "");

and replace with

$find = array("&#092;", "&amp;", "<br />", "&lt;", "&gt;", 
                      "&quot;", "&#39;", "&#33;", '<p>', '</p>', '<div>', '</div>');
        $replace = array("\\", "&", "", "<", ">", '"', "'", "!", "", "", "", "");

Are you planning to make the same plugin for IPS 4.0?

[RedEnzian]

Hello ehku,

I'am sorry to say, that i've currently not the time to update this extension ... additionally invision changed a lot in the way how the editor works  (didn't have looked closer but as far as i understand, there are no BBCodes and the plugin has to be integrated into CKEditor ... you can try http://ckeditor.com/addon/eqneditor which is an Latex Plugin for CKEditor)

[ehku]

Thanks for the reply @RedEnzian. I guess that I will have to learn how to create the plugin myself 

you can try http://ckeditor.com/addon/eqneditor which is an Latex Plugin for CKEditor)

Unfortunately this does not support graphics packages such as TikZ, which is important to my forum
