Code: [Select]
$txt = preg_replace( "#\[yt\]http://www.youtube.com/watch?v=(.+?)\[/yt\]#is", '<embed src="http://www.youtube.com/v/\\1" type="application/x-shockwave-flash" wmode="transparent" width="512" height="313" allowfullscreen="true" />', $txt );

Okay this is my code just for inserting it into HTML, the problem is whenever I try to use:

Code: [Select]
[yt]http://www.youtube.com/watch?v=l1G7TJD6Xu0[/yt]
On my form to enter it does not work?  But if I use

Code: [Select]
$txt = preg_replace( "#\[yt\](.+?)\[/yt\]#is", '<embed src="http://www.youtube.com/v/\\1" type="application/x-shockwave-flash" wmode="transparent" width="512" height="313" allowfullscreen="true" />', $txt );
Code: [Select]
[yt]l1G7TJD6Xu0[/yt]
It works.


But I want to use the full URL of the youtube, so I don't want my users to copy/paste just the "l1G7TJD6Xu0" Code , any help? Thank you

Hi there,

This isn't really a bbcode parser problem, but it kind of is. And I am awful at explaining things, as you have noticed.

The problem is that I'd like to allow input for the main page of a site. But the part has this structu
Code: [Select]
<div class='mainheader'>TITLE</div>
<div class='content'> The content of the webpage blabla</div>
I'd like this whole page to be changeable, so also the title and the content. But how can I ensure that people use the content div after the mainheader div?
I would like it if it were possible that they only needed to 'select' the header, how can I do this?

Thanks in advance!

Right now i used the following code to convert bbcode to html/php.
i also need to incorporate QUOTE=name and URLS as well..how do i do that?

Code: [Select]
function bbcode_format ($str) {
$str = htmlentities($str);

$start = array(
'/\[b\](.*?)\[\/b\]/is',
'/\[i\](.*?)\[\/i\]/is',
'/\[u\](.*?)\[\/u\]/is',
'/\[a\=(.*?)\](.*?)\[\/a\]/is',
'/\[color\=(.*?)\](.*?)\[\/color\]/is',
'/\[img\](.*?)\[\/img\]/is',
'/\[header\](.*?)\[\/header\]/is'
);

$finish = array(
'<strong>$1</strong>',
'<em>$1</em>',
'<u>$1</u>',
'<a href="$1">$2</a>',
'<span style="color: $1">$2</span>',
'<img src="$1" />',
'<span class="h3">$1</span>'
);


$str = preg_replace ($start, $finish, $str);

return $str;
}

I was wonder how I could make some BBcode for my messaging system I made for a website. I made some simple ones like just by replace [ red ] with font color etc. I want to know how to do something like this:

[ url = http://google . ca] Google [ / url ] without the spaces.

hi, i have the following which parses the quote tag and replaces it with a span

$bb[] = "#\[quote\](.*?)\[/quote\]#si";
      $html[] = "<span class='quote'>\\1</div>";

what i would like however is for the bbcode to be Quote from: xxxx

where xxxx is the name of the person you are quoting.
so how would i parse this? I also need the same for font color but if someone can provide a solution to this one then i think i could work it out.

I'm trying to work on BBCode for a forum.
Code: [Select]
<?php
$bb_Code = array(
'[ code]' => '<code>',
'[ /code]' => '</code>'
);
foreach ($bb_Code as $value => $replace) {
$text = str_replace($value, $replace, $text);
} ?>

Question is.. how would I get it so when I insert information into the database it gets cleaned (strip_tags, etc.) but doesn't disturb what is in the [ code ] tags?
So basically it makes the html, etc. in the [ code ] tags just plain text?

Thanks in advanced.

I have this function:
    function bbcode($input){
        $input = strip_tags($input);
        $input = htmlentities($input);
        
        $search = array(
                    '/\[b\](.*?)\[\/b\]/is',
                    '/\[i\](.*?)\[\/i\]/is',
                    '/\[u\](.*?)\[\/u\]/is',
                    '/\[img\](.*?)\[\/img\]/is',
                    '/\[url=http://(.*?)\](.*?)\[\/url\]/is',
                    '/\[color=(.*?)\](.*?)\[\/color\]/is',
                    '/\[yt\](.*?)\[\/yt\]/is',
        );
        
        $replace = array(
                    '<b>$1</b>',
                    '<i>$1</i>',
                    '<u>$1</u>',
                    '<img src="$1" style="border:0">',
                    '<a href="$1">$2</a>',
                    '<font style="color:$1">$2</font>',
                    '<object width="660" height="405">
                    <param name="movie" value="'.str_replace("watch?v=", "v/", $1).'" />
                    <param name="allowFullScreen" value="true" />
                    <param name="allowscriptaccess" value="always" /><embed type="application/x-shockwave-flash" width="660" height="405" src="'.str_replace("watch?v=", "v/", $1).'" allowscriptaccess="always" allowfullscreen="true"></embed>
                    </object>',
        );
        
        return nl2br(preg_replace($search,$replace,$input));
    }
There is an error on code:
<param name="movie" value="'.str_replace("watch?v=", "v/", $1).'" />
and on:
<param name="allowscriptaccess" value="always" /><embed type="application/x-shockwave-flash" width="660" height="405" src="'.str_replace("watch?v=", "v/", $1).'" allowscriptaccess="always" allowfullscreen="true">
How can i use str_replace in this situation ? :S

Code: [Select]

[b][i][u]

test test test test test test test test test test test test test test test.

[/b][/i]/[u]


If I need to cut the first five words, the bbcode closing tags will be remove.

Everything works fine, unless I add this stupid thing to get rid of people using HTML
Code: [Select]
$text = pun_htmlspecialchars($text);
Once I add that to my function, no bbcodes work at all?  But I cant use html.. (which is good) but I need to beable to use BBCODE, and parse hackers from using html also, any help?



MY CODE absolutely destroyed the forum page

Hi all,

I've added bbcode to my forum on my website but I don't want users to be able to add javascript (or better put, I only want links to be http, https, ftp type links). How can I do this?

I am trying to replace image code and resize it at the same time
but gave me error.
Warning: getimagesize($1): failed to open stream: No such file or directory in C:\wamp\www\ . . . . .



public function resize_Images($originalImage,$toWidth,$toHeight){
    
    // Get the original geometry and calculate scales
    list($width, $height) = getimagesize($originalImage);
    $xscale=$width/$toWidth;
    $yscale=$height/$toHeight;

public function bhl_bbcodes($str) { 
  
    $simple_search = array(  
                '/\[img\](.*?)\[\/img\]/is', 
    );  
  
    $simple_replace = array(

);
    $str = preg_replace ($simple_search, $simple_replace, $str);   
  
    return $str;
}

I have this function:
    function bbcode($input){
        $input = strip_tags($input);
        $input = htmlentities($input);
        
        $search = array(
                    '/\[b\](.*?)\[\/b\]/is',
                    '/\[i\](.*?)\[\/i\]/is',
                    '/\[u\](.*?)\[\/u\]/is',

                    '/\[url=http://(.*?)\](.*?)\[\/url\]/is',
                    '/\[font color=(.*?) size=(.*?) face=(.*?)\](.*?)\[\/font\]/is',
        );
        
        $replace = array(

                    '<font style="color:$1;font-size:$2;font-face:$3">$4</font>',
        );
        
        return preg_replace($search,$replace,$input);
    }
Now when i use this command($komentar is variable which is loaded from mysql):
echo bbcode($komentar);
it shows me this error:
Warning: preg_replace() [function.preg-replace]: Unknown modifier '/' in /home/dotars/public_html/includes/functions.php on line 212

What is wrong here ? :S
