[SOLVED] regex help

[Renlok]

i have bbcode but i'm having problems with it, half the bbcode doesn't work and ive no idea why and rubbish at using regex and this is the onyl time ive ever used it so its probably just written rubbish but i dunno any hellp would be great

 

..ill just post the bits that don't work.

 

$string = $_POST['message'];

$patterns = array( 
'`\[color=#([0-9]{6})\](.+?)\[/color\]`is', 
'`\[colour=#([0-9]{6})\](.+?)\[/colour\]`is',
'`\[color=([a-z])\](.+?)\[/color\]`is',
'`\[colour=([a-z])\](.+?)\[/colour\]`is',
'`\[img\](.+?)\[/img\]`is', 
'`\[url=([a-z0-9]+://)([\w\-]+\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^ \"\n\r\t<]*?)?)\](.*?)\[/url\]`si', 
'`\[url\]([a-z0-9]+?://){1}([\w\-]+\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^ \"\n\r\t<]*)?)\[/url\]`si', 
'`\[url\]((www|ftp)\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^ \"\n\r\t<]*?)?)\[/url\]`si', 
); 

$replaces =  array( 
'<span style="color:#\1;">\2</span>',
'<span style="color:#\1;">\2</span>', 
'<span style="color:\1;">\2</span>',
'<span style="color:\1;">\2</span>',
'<img src="\1" alt="" style="border:0px;" />', 
'<a href="\1\2">\6</a>', 
'<a href="\1\2">\1\2</a>', 
'<a href="http://\1">\1</a>', 
); 


$string = preg_replace($patterns, $replaces , $string); 

 

i have loads of other parts to the bbcode that work fine i dont know why these bits just dont work

I tested your code, and it work perfectly.  I tried color, img and url tags.

 

Maybe the problem is with the string you are passing in?
