bbcode

[doddsey_65]

ok bare with me if this sounds stupid.

 

How do i get it so that bbcode can be added within a textarea tag? im assuming it is a lot of str_replace. is there a tutorial on this somewhere?

Do you mean add bbcode tags (eg ) when the user clicks a button? For this you'll want to use javascript

 

Or to parse bold to bold?

For parsing bbcode you'd use regex

$str = 'This is some [b]text[/b], bold and [b][u]underlined[/u][/b]

[i]italics[/i], [b]bold[/b], [u]underline[/u]';

$str = preg_replace('~\[b\](.*?)\[/b\]~', '<b>\\1</b>', $str);
$str = preg_replace('~\[i\](.*?)\[/i\]~', '<u>\\1</u>', $str);
$str = preg_replace('~\[u\](.*?)\[/u\]~', '<u>\\1</u>', $str);

echo nl2br($str);
