Converting HTML To BBCode

March 7, 2006 on 9:01 pm | In PHP |

I am currently learning PHP, so I set out to write an application which would convert my HTML-coded tutorials into BBCode suitable for forums. That goes without saying that my code failed miserably.. I was not too far off though; I got the general gist of it. So, I decided to ask the wonderful guys and gals on the ‘General user’ PHP mailing list (which, by the way, means what it says about being of very high volume!), and they came up with a solution.

The solution involved regular expressions (or reg-exp, for the abbreviation fanatics out there) - which I am proud to say I understood none of. Hopefully I’ll soon be onto regular expressions so that I can figure out what it means - I remember the days I thought HTML was cryptic! How naïve I was.. Reg-exp is impossible to understand in my opinion, although I’m sure the more advanced PHP coders among you will say the contrary.

Enough of my rambling - here’s the page you can use if you ever want to translate HTML code into forum-usable BBCode: HTML To BBCode.

Note: Only the following tags (and their closing ones) are currently supported -

<strong>
<b>
<em>
<i>
<ul>
<ol>
<li>
<a>
<img>

It works surprisingly well - although note: outputted BBCode may be different to the BBCode used on some forums. BBCode which is returned by this script is proven to work on vBulletin forums.

Excellent app. I occasionally get sent submissions in HTML that need converting so I may well use and abuse this!

A great app to have. I thought of creating a BBCode parser myself for my CMS although I think HTML is better for a CMS because you’re building a site and you shouldn’t limit yourself to BBCode.

Ray - Hehe, no problem!

Hari - Thanks You’re right, HTML is probably a better choice for the CMS - it gives the user much more freedom than sticking to BBCode tags. Plus, with HTML there’s always room to expand the CMS with new tricks - with BBCode, any new implementations would be a bit more complex. At least that’s MHO

If you want a visual regular expression editor you can use KRegExpEditor. It’s very easy to build regular expressions if you understand the logic behind what you want. You needn’t worry about the syntax. This tool will generate it for you.

Very nice, but why dont u remove the html tags that can’t be converted? such as table and td? Just leave the bbcode with the working ones.

Thank you.

That is a good point.. I think the original idea was that, because there are so many different variations of BBCode, those HTML tags which were not converted were left in the code so that the user could then convert those themself if their forum’s BBCode allowed it.

But, I do see your point - once I’ve furthered my knowledge of reg-exp (or, rather, get to the holidays so I can refresh my memory!), I will add the option to do that.

Thanks for the input!
