[SOLVED] BBCode Help.

[lszanto]

I'm working on a news system and I've got the bbcode working but I'm working on a function to turn html into bbcode so they can edit news, this is how far I've got and everything works apart from the <img src="imagelink" /> to bit so please help.

 

function unbbcode($post) {
//Make the vars.
$b = "/\<b\>(.*?)\<\/b\>/is";
$i = "/\<i\>(.*?)\<\/i\>/is";
$u = "/\<u\>(.*?)\<\/u\>/is";
$url = "/\<a href=(.*?)\ target=\"_blank\"\>(.*?)\<\/a\>/is";
$img = "/\<img src=(.*?)\ alt=\"image\" \>/is";

//Run preg_replace.
$post = preg_replace($b, "[b]$1[/b]", $post);
$post = preg_replace($i, "[i]$1[/i]", $post);
$post = preg_replace($u, "[u]$1[/u]", $post);
$post = preg_replace($url, "[url=$1]$2[/url]", $post);
$post = preg_replace($img, "[img=$1]", $post);

//Do str_replace loop for smilies.
for($i=0; $i < 23; $i++) {
	$post = str_replace("<img src=\"images/smilies/$i.gif\" alt=\"Smiley$i\" />", ":$i:", $post);
}

//Return results.
return $post;
}

Hi,

 

I use something like:

 

	$BBCode = array(
"<center>" => "
[center]", "</center>" => "[/center]
", 
"<b>" => "[b]", "</b>" => "[/b]", 
"<u>" => "[u]", "</u>" => "[/u]",
"<i>" => "[i]", "</i>" => "[/i]",
"<img src=" => "[img=http://'", "'>" => "]",
"<li>" => "[list][*]", "</li>" => "[/list]",
"<font color='red'>" => "[color=red]",
"</font>" => "[/color]",
);
$value = str_replace(array_keys($BBCode), array_values($BBCode), $value); 
$value = mysql_real_escape_string(strip_tags(trim($value))); 
return $value; 
}

 

Then reverse it for use with editing.

I might try that but is there anyway to do it with preg_replace, I find it easier to use and it does the job better for me.

replace the

[img]
with
<img src="

to
" />

Thanks, that seemed to work for me.
