[SOLVED] BBcode Parsing Problems (preg_replace)

[Grego]

I've stored all my BBcode terms in a MySQL database containing, amongst other things, their patterns and replacements. For example:

 

Pattern: /\[b\](*.?)\[\/b\]/is

Replacement: <strong>$1</strong>

 

There are five of these records: b, i, u, url, img

 

I then have a piece of code which draws out the patterns and replacements and puts them in an array. I use preg_replace to replace all the patterns with their respective replacements. For some reason, I'm getting an error saying: "Warning: preg_replace() [function.preg-replace]: Compilation failed: nothing to repeat at offset 6 in /home/commande/public_html/gregoland/functions_bbcode.php on line 20". I've tried googling this but have only returned examples of it rather than solutions. Does anybody know what's wrong and how I can get rid of this error?

 

This is the code I'm using:

 

  $bb_codes_q = $db->execute('SELECT * FROM `bbcode`');
  $bb_patterns = array();
  $bb_replaces = array();

    while($bb_codes = $bb_codes_q->fetchrow()){
    array_push($bb_patterns,$bb_codes['pattern']);
    array_push($bb_replaces,$bb_codes['replace']);
    }

  $bb_text = preg_replace($bb_patterns,$bb_replaces,$bb_text);
  return $bb_text;

Try a print_r() for both arrays before you do the preg_replace(). Maybe there is an error in your regexp.

I've tried that and I can't see anything wrong with either array. I tried too to replace the arrays with an empty "array()". When I replaced $bbcode_patterns, I found that the error had gone. So I've narrowed it down to that variable being wrong. Here is the print_r for it:

Array
(
    [0] => /\[b\](*.?)\[\/b\]/is
    [1] => /\[i\](*.?)\[\/i\]/is
    [2] => /\[u\](*.?)\[\/u\]/is
    [3] => /\[url\=(*.?)\](*.?)\[\/url\]/is
    [4] => /\[img\](*.?)\[\/img\]/is
)

I don't know If this will help or not, maybe it will be easier???

 

but this is what I use for bbc: http://phpsnips.com/snippet.php?id=41

/\[b\](*.?)\[\/b\]/is

 

 

That's an invalid pattern x.x

 

* means number of occurances >= 0 and . means any character, so I think you mean .*, not *..

[Grego]

You're right Corbin - though I figured it out before you said

 

I replaced all the (*.?)'s with (.*) and it works fine. A really stupid error. :-\

 

But thanks to all anyway.

That's also what the error meant since * meant repeat, and there was nothing before it ;p.
