trying to copy wiki code

[ianco]

Hi All

 

I want to use wiki style bold (''') and italic ('') code form my form.

 

So, it would be easy to use str_replace() for the opening tag but if you are using '''hello''' to bold the word hello, how can you differentiate the tags? I guess you would need some code to replace this alternatively but I haven't been able to find anything.

 

I think Wikis are built from php so has anyone got any ideas?

 

Many thanks

You use regular expressions instead.

$bolded = preg_replace("/'''(.*?)'''/", '$1', $text);

$italicized = preg_replace("/''(.*?)''/", '$1', $text);

Bold first, otherwise you'll end up with titles looking like 'this'. (Or you could adjust the expressions.)

thanks a lot. That's a big help.

HI again,

 

I now want to reverse my preg_replace function

 

$content = preg_replace("/(\\\'\\\')(.*?)(\\\'\\\')/", "<em>$2</em>", $content);

 

This doesn't work:

 

$content = preg_replace("/\<\e\m\>(.*?)\<\/\e\m\>/", "\'\'$1\'\'",$content);

 

any ideas?

 

Thanks

Question: why do you need to reverse it?

[ianco]

Well, at the minute the data is stored in a database, I want to edit it in a textarea.

Right. The best thing is to store two versions of the text: one with the wiki code and one converted to HTML.

... | wikitext   | htmltext
----+------------+----------------------
    | '''Bold''' | Bold

One is for editing, which is converted to HTML when it changes, and the other is so that you don't have to convert the wiki markup every time the content is displayed. No reversing necessary.
