What hook is your replacement plugin using, is it before or after bbcode replacement?

OK, there may be some more elegant way someone knows to do it (in which case, please post it), but here's what I came up with:

Code:
$word = array(
'google',
'yahoo'
);

$link = array(
'<a href="http://google.com">google</a>',
'<a href="http://yahoo.com">yahoo</a>'
);

$parts = preg_split('#(<a|</a)#i', $this->post['message'], -1, PREG_SPLIT_DELIM_CAPTURE);

$newmsg = '';
$inlink = false;
foreach ($parts as $part)
{
    if (strcasecmp($part, "<a") == 0)
        $inlink = true;
    else if (strcasecmp($part, "</a") == 0)
        $inlink = false;
    else if (!$inlink)
        $part = str_replace($word, $link, $part);
    $newmsg .= $part;
}

$this->post['message'] = $newmsg;
I haven't tested it extensively so if you try it you might want to check a lot of posts to make sure they look OK.

I am sorry,

There is problem on images TAG
I need to exclude images IMG tags inside post's to NOT effected.

I am sorry kh99, please help me to fix it.


Thank you

Yeah, I had a feeling you'd evenutally find a problem with that. It's hard to get stuff like that to be bulletproof (or at least it's hard for me).

Anyway, try this:

Code:
$word = array(
'google',
'yahoo'
);

$link = array(
'<a href="http://google.com">google</a>',
'<a href="http://yahoo.com">yahoo</a>'
);

// Match any HTML tag, this will be the delimiter in preg_split
$regexp = "/(<\/?\w+((\s+(\w|\w[\w-]*\w)(\s*=\s*(?:\".*?\"|'.*?'|[^'\">\s]+))?)+\s*|\s*)\/?>)/i";

// Capture delimiters and offsets. This will also capture things multiple times because of the
// multiple parens used in the pattern, so we'll have to skip them in the loop below
$parts = preg_split($regexp, $this->post['message'], -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_OFFSET_CAPTURE);

$newmsg = '';
$intag = false;
$offset = 0;
foreach ($parts as $part) // $part is array, 0 = string 1 = offset (because of PREG_SPLIT_OFFSET_CAPTURE)
{
    if ($part[1] < $offset) // ignore parts from other parens in regexp
        continue;
    $offset = $part[1] + strlen($part[0]);

    if (strncasecmp($part[0], '<a', 2) == 0 ||
        strncasecmp($part[0], '<img', 4) == 0)
    {
        if (strcasecmp(substr($part[0], -2), '/>') == 0) // check for self-closed tag
            $intag = false;
        else
            $intag = true;
    }
    else if (strncasecmp($part[0], '</a', 3) == 0 ||
            strncasecmp($part[0], '</img', 5) == 0)
        $intag = false;
    else if (!$intag)
        $part[0] = str_replace($word, $link, $part[0]);
    $newmsg .= $part[0];
}

$this->post['message'] = $newmsg;

It's getting ugly now...

Thats IT, :D:D:D:D

Great, I really very appreciate your patience and help,


Thank you so much kh99.

I would have searched for " google" or "google " (note the space) and replaced them with " <a href="http://google.com">google</a> " and the same for yahoo. Requiring the space as part of the string would mean www.google.com or http://google.com wouldn't be effected. The extra space introduced by the replacement is usually ignored anyway.

kh99 10-11-2010 10:09 PM
That's a good idea, that might have solved the OP's problem. I guess since it says "Anchor Text" in the first post I was thinking the problem was the text and not the url. But it might have been a translation thing because it makes more sense that the url would be the problem.

He seems to have edited the first post, I thought this was more in line with what he originally said but now I'm not so sure.
