Making BBCode

Mew151

I want to do something like this:

reverse_template("That was [b]cool![/b]", "[b]{TEXT}[/b]", "<span class=\"bold\">{TEXT#}</span>");

And have it return something like this:

That was <span class="bold">cool!</span>

I have a good plan on how to do it, but I have no clue on how to keep the "cool!" substring intact. 😕

Basically, it will change the string to something like this:

"That was <span class="bold">{TEXT1}</span>"

And then after changing all the tags, it'll replace "{TEXT1}" to "cool!"

Again, I have no idea how to get that substring...:xbones:

perhaps: BBCode Functions

Well, I wanted to make my own BBCode function, so I can customize it for any needs...

dagon

you can create anything you like with bbcode_create() you define start end and replace. but if its not enough for your preg_replace() is your next stop. There are of course template engines that do a lot of this sort of thing.

Mew151

I already have a plan on how to do everything...
I just want to know how I could get the strings in between the tags.

dagon

no plan survives contact with the enemy :-)

preg_replace() - preg_match()

Mew151

alright, I completely changed my plan... >.>
But now, something is happening...
Here's the string I input:

"[[i][/i]i]This[/i] [[i][/i]b]is[/b] [b[i][/i]]cool![/b]"

However, it outputs as this:

"<span class="italic">This</span> <span class="bold">is[/b] [b]cool!</span>"

and the php your using is?

Mew151

It says 4.4.9, but it also says PHP 5 is installed. :queasy:

dagon

no, i mean the code you used to get the results you are having an issue with.

nevvermind

$pattern = '#\[b\](.+?)\[/b\]#';

Use that. As for the replacement code, it got on my nerves. I was doin' something wrong and it did not replace the matches.

Cna somebody point out a correct preg_replace for op?

johanafm

$r = '<span style="font-weight: bold;">\1</span>';
$s = "[i]This[/i] [b]is[/b] [b]cool![/b]";

$s = preg_replace($pattern, $r, $s);

Mew151

Thanks!
I'm a little confused with the preg_replace regular expressions.
I'm used to the POSIX ones. :o

johanafm

Well, you had the pattern right, and in this case I don't think there would have been any difference between posix and preg, but since I never really used posix, I might be wrong...
All you needed was the \1 back reference to the capturing subpattern (.+?) in the replacement string.
