HTML to BBCode

[Stu]

Bit of a different one here for you all; I want to go from HTML code to BBCode. Why you ask? I shall explain 🙂

I am co-creating a forum with a mate and would obviously like our members post using different font styles, add hyperlinks, etc. To insert them into a database, we used the following code:

Edit: It would appear that the forum doesn't like my code so here is the link to see it in a text file: http://www.2312.co.uk/code1.txt

With $message being the text that the user is posting. All displays correctly but the problem comes when you wish to edit the post. I need to convert all the HTML code back into HTML code for two reasons:

1. So it's less confusing for my users
2. So I can use the strip_tags() function to prevent any malicious code being used.

I've struggled for a good few hours with this code now and have got virtually nowhere. I have managed to convert the bold, italic and underline tags accordingly but am stuck after that.

Here is the code that I used to convert the bold, italic and underline tags back to HTML:

Edit: It would appear that the forum doesn't like my code so here is the link to see it in a text file: http://www.2312.co.uk/code2.txt

It would therefore seem logical to me that the following code would be correct for converting URLs:

Edit: It would appear that the forum doesn't like my code so here is the link to see it in a text file: http://www.2312.co.uk/code3.txt

But using that code gives the following error:

Warning: REG_BADRPT in /home/.sites/146/site439/web/hh/forum/edit.php on line 46

Line 46 is obviously the code that attempts to convert URLs.

Could you please offer me some pointers as to what I am doing wrong?

Thanks very muchly

its eaisier to use htmlspecialchars() when inserting the text into the database, and when displaying the text use the preg_replace() function to convert the bbcode tags coming from the database.

so when a user edits a post, the bbcode will be there since the actual bbcode is being inserted into the database.

You are a class act 🆒 Thank you ever so much. So simple and there was I looking to do something complicated.

Once again, thanks 🙂
